Definitions

  • the invention relates to a winch for ropes, in particular for running good, such as traps and pods on sailing vessels.
  • winches usually have a rotatable winch drum mounted in a direction Holze, which is mounted on a base part, for example on the deck of a boat, mounted Winschfuß- or -sockel.
  • a winch gear drives the winch drum.
  • US 4,084,793 shows a winch with an electric motor disposed inside the drum, which is flanged to the base and drives the winch drum via a gear arranged on top of the winch drum. It is a winch in which one end of the rope to be retrieved is attached to a flange which rotates together with the winch drum. So you can only get as much rope as the winding capacity of the winch drum. For many purposes aboard a ship, therefore, it is not useful, for example as a Schotwinsch, because there, for example. at a turn, the sheet must be thrown completely. Also disturbs the large, the gear-containing head and it is not possible to manual operation.
  • the object of the invention is to provide a motor winch as compact as possible, in which restrictions with respect to mounting locations are largely eliminated.
  • the winch can be mounted at the point where the trouble-free running of the ropes to be operated by her, such as traps or pods, is guaranteed and where she disturbs the least on deck. It is only necessary to lay the supply lines, which can usually be done between the deck structure and a ceiling panel of the cabin. The attachment to the mast is possible with a standard winch console.
  • a control unit When equipped with an electric motor, a control unit is provided with a starting contactor, which is controlled via a low-current control circuit from an operating switch on the deck.
  • the controller may further include an overcurrent fuse similar to a circuit breaker that serves to limit a maximum pull force in addition to the fuse function. Because of the proportionality between traction and power consumption overloading of the rope or the associated sails can be prevented even if accidentally too long operation.
  • the motor takes place in a tubular support body and can be mounted there with the axis of rotation parallel to the axis of rotation.
  • the tubular support body on which the winch drum can be mounted via needle bearings represents an equally lightweight and stable support structure for the winch drum and transmits the forces acting on the winch considerable rope forces well on the winch.
  • the winch on an additional manual drive which, as in mechanical winches, via a pluggable into the upper winch head winch handle is actuated.
  • the drive shaft for this can protrude eccentrically through the engine compartment and so pass the slightly eccentric motor.
  • a known Disthol 2015 can be used, which forms the head of the winch drum and in the Rope is introduced via a guide.
  • the width of the gripping groove is variable in order to adapt to different rope diameters can, wherein the lower Nutbegrenzung an upper flange of the winch drum may be and the upper Nutbegrenzung a resiliently axially movable annular disc.
  • the motor may be a gear motor with an integrated motor gear, for example a planetary gear, which forms a gear precursor.
  • the motor itself is preferably a DC shunt motor which has a very favorable speed / torque characteristic in the present case, i. its torque increases as the speed decreases. Due to a high idling speed of the order of 14,000 revolutions per minute, it can bring high performance with a small size.
  • the gear pre-stage sets this speed down three to five times, so that the desired winch drum idling speed of about 80 - 100 revolutions per minute is achieved in the downstream winch gear stages with low gear number. With a winch drum diameter in the order of 100 mm, this results in a Seilhol horrin between 25 and 30 meters per minute; for the application on yachts an ideal value.
  • the winch gear and the motor gear are preferably not self-locking spur gear, compared to commonly used worm gears also have a very good efficiency. This is especially true when preferred the winch gear runs in an oil bath, which can be designed maintenance-free by appropriate lubricants for life. This eliminates the time-consuming and difficult on-board periodic winch maintenance.
  • the winch gear can preferably be arranged in the base and contain three gear levels, each forming a gear stage. These can be made up of at least two disks stacked one above the other like a disk be, wherein one of the boards may be formed by the support body for the winch drum.
  • the transmission direction is from bottom to top, ie the motor shaft projects through to the end of the winch socket and the individual gear stages are built on it, so then the last gear with a transmission gear reach the inner edge of the winch drum and can drive this.
  • Freewheel lock prevent one hand, a reverse rotation of the winch drum and on the other hand ensure that the motor drive the manual drive train does not run, so not accidentally plugged winch handle leads to the risk of accidents.
  • a freewheel uncouples the engine during manual operation so that it does not need to be rotated.
  • the winch may be provided with a finning device containing an electrical control device with which the rope under tension can be loosened.
  • the electric motor can be used as a regulated brake.
  • the manual drive is preferably connectable via a manually operable clutch.
  • the winch drum freewheel In order to perform a reverse rotation of the winch drum against the direction Holraum, the winch drum freewheel must be turned off. This can be done by electrical actuation, for example by electromagnets or electric servomotors, which disengage the pawls of the freewheel during the reverse rotation process and hold there. Because the pawls are normally braced when the winch is under the tension of the rope, this tension can be overcome by first driving the engine slightly in the haul direction, for example a fraction of the amount corresponding to a locking pitch, and then the Latches are disengaged. Then, when the winch drum turns back under the pull of the rope, the motor runs backwards.
  • the controller can turn on a braking resistor, which limits the reminding function characterized in that now the engine is running as an engine brake.
  • This electrical braking resistor does not need to be designed too large, since the reversing function is usually limited to a slight release.
  • a resilient retaining lever is preferably provided on the Dhol worn, behind which the rope is placed and the considerable circumferential distance from the guide, i. the guide finger, which lifts the rope from the winch drum in the Selftail groove is arranged.
  • the rope is guided on both sides of the Selftail groove and it is effective in both directions.
  • This novel retention lever is also advantageous for other winches with return function.
  • the rope adheres to the winch on the outer surface of the winch drum by friction with self-reinforcing, ie the applied by the Dihol Published initial cable is amplified over several turns of the rope on the winch drum respectively.
  • Conventional winch drums are roughened or knurled on the outside to increase the friction factor. This is not very rope-friendly and damages its surface. It has also become known to provide the winch drum with numerous uniform distributed over the circumference longitudinal ribs.
  • FIG. 1 shows a winch 11, which is intended for the fetching and enforcement of ropes, such as pods or traps of sailboats. It is attached to a mast with a winch foot or base 12 on the deck 13, cockpit shroud or, usually by means of a console.
  • a cord 15 shown in broken lines is guided in several turns from bottom to top around a winch drum 14.
  • the winch drum consists of a substantially cylindrical or slightly conical winch drum surface 16, on the circumferentially at greater distances from one another groups of two substantially vertical ribs 17 are pronounced outwards. These may also be slightly inclined, in accordance with the inlet and cable guidance properties.
  • a bell-shaped winch drum base 18 which has a substantially larger diameter than the winch drum 16 and the obliquely downward connecting surface between a lower cylindrical portion 19 and the winch drum surface 16 forms an inlet guide surface 20 for the cable 15 ,
  • the cylindrical portion 19 engages over there offset upper portion of the winch base 12 and together with this forms a cylindrical body.
  • the upper free end of the winch is formed by a winch head 21, which includes a Doublehol- (Selftail) device 22.
  • This is formed by a circumferential gripping groove 23, which, as is apparent in particular from FIGS. 7 and 8, is variable in its groove width.
  • the two nutbegrenzenden gripping bodies are on the one hand formed by a flange 24 at the upper end of the winch drum and on the other hand by an annular disc 25 which guided by means of guide pins 26 in the direction of the winch axis 28 and pressed by compression springs 27 in the position shown in Figure 7 with the smallest gripping groove 23 becomes.
  • Winchkurbelnuß 32 provided in a conventional winch handle for manual operation can be inserted. While normally the rope in the gripping groove rotates almost a complete revolution until shortly before the guide 30, where it is deflected out of the groove by an ejector 33, in a later described embodiment with reference to FIGS. 10 to 23 a retaining device 34 with a retaining lever 35 is provided appropriate.
  • This is, as shown in FIG. 23, pivotally mounted in the winch cover about an axis parallel to the winch axis 28 formed by one of the cap screws 45 and resiliently supported by a spring 125 and has a hook 15 extending under the gripping groove cross-hook shape.
  • a retaining lug 36 holds the rope in the gripping groove, while it is peeled off from the gripping groove by the hook opening 37 and the adjoining hook shank 38. This retainer ensures that in later described manner, the rope when firing, ie at a winch drum rotation in Fierides 39 (counterclockwise), is not thrown out of the gripping groove.
  • Fig. 2 shows the internal structure of the winch with its gear 84 in conjunction with Figures 3 to 6, which represent individual transmission levels and levels.
  • the winch base 12 is formed of two superimposed transmission plates 50, 51 which form a closed and sealed to the outside and compared to the rest of the winch interior, two-part gear chamber 40 which receives an oil bath, which provides for the lubrication of the transmission.
  • a winch support body Arranged over the blanks is a winch support body which is in the form of a thin-walled tube having a cylindrical portion 41, a slightly enlarged space 43 for the third gear stage, and a flange 144. At the upper free end, an inner flange is provided in the screws 45 protrude that hold the winch head 29 and end cap.
  • the winch drum 14 On the cylindrical portion 41 of the support body 44, the winch drum 14 is mounted by means of needle bearings 46, in its upper and lower portion. This results in a very good power transmission with low material costs.
  • a plastic friction washer 48 receives the pulling forces of the rope acting down on the winch drum.
  • the tubular cylindrical portion 41 of the support body 44 surrounds a likewise cylindrical engine compartment 47, which extends from the upper transmission plate 51 to the winch head 21.
  • an electric geared motor 52 is arranged in this room. He has an elongated shape and is in the engine compartment 47 with the winch axis 28 parallel motor axis 53, slightly off-center offset, arranged, flanged onto the upper transmission plate 51.
  • the motor 52 is a shunt DC motor that reaches very high speeds of up to 14,000 rpm at idle and this by an internal planetary gear 54 to about 4,000 rev / min. decreases. Under load, the speed goes down under torque increase. This is desirable because both when using as a fall and as a Schotwinsch after initially pulling through the lots, the final Dichtholen should not go too fast.
  • the motor shaft 55 projects through the third gear stage 42 and the upper gear plate 51 into the lower gear board 50 and is stored there and rotatably connected to a drive pinion 56 which engages in a gear 57 of considerable larger diameter (Fig. 3).
  • the gears are indicated only by their dashed circles drawn partial circles.
  • the gear wheel 57 is non-rotatably mounted on the shaft 58, which protrudes from the first gear plane (board 50) into the second gear plane (board 51), which also forms the second gear stage (FIG. 4). There it is rotatably connected to a pinion 59, which in turn drives a gear 60 with a larger diameter.
  • the gear 60 has a toothed outer rim 61 and a hub 62 which is rotatably connected to a shaft 63.
  • a pawl freewheel 64 is provided between outer ring 61 and hub 62.
  • Three spring-loaded pawls 65 arranged in the vicinity of the circumference of the hub and obliquely projecting beyond the circumference thereof engage in reverse sawtooth-like recesses 66 on the inner periphery of the outer rim 61.
  • the shaft 63 projects through the upper surface of the circuit board 67 of the transmission plate 51 sealed and carries there rotatably a pinion 68 which drives an intermediate gear 69 which is mounted on a shaft 70. It engages in an internal ring gear 71 on the inner circumference of the winch drum and drives it (FIG. 5).
  • Fig. 6 shows that on the inner circumference of the winch drum also a sawtooth-like negative toothing 72 is provided, engage in the pawls 73 of the same type as previously described. They are mounted on the support body 44 and thus form a pawl freewheel 75 for the winch drum, which locks them against reverse rotation.
  • a gear 77 driven by a pinion 76 is also mounted.
  • the pinion 76 is rotatably provided with a drive shaft 98 for mechanical actuation, which is connected via a square adapter 99 (FIG. 2) with the winch crank nut 32.
  • the shaft 98 is parallel, but eccentric to the winch axis 28 through the engine compartment 47, close to the Trageniawandung 41, so that in the engine compartment 47 sufficient space for the engine remains.
  • the gear 77 also includes a pawl freewheel 78 and is constructed in the same manner as the freewheel 64 of outer rim 79, hub 80, pawls 81 and inner helical teeth 82.
  • the hub sits on the shaft 70 and also drives the idler gear 69.
  • FIG. 9 The electrical connection of the winch is shown schematically in FIG. 9: Positive and negative supply lines 87, 88 coming from an on-board battery 86, possibly via main switches and fuses, lead to a control unit 89 which contains a contactor 90 and an overcurrent switch 91 in the positive line ,
  • the relay 90 is, optionally via an auxiliary relay, driven by a low power circuit 92 in which a control switch 93 is located for the winch.
  • the control dial 89 may be located below a suitable location and the control switch 93 is preferably a robust and protected against moisture and possibly by a lid against accidental operation button, which is mounted in the vicinity of the winch on deck.
  • the winch operates as follows:
  • the cable 15 is in the manner shown in Fig. 1 around the winch drum and is introduced via the guide nose into the gripping groove 23.
  • the rope can be ridden through, for example, to quickly catch up with a sheet after a turning maneuver.
  • the winch drum can rotate freely in the direction of travel 31, because the pawl freewheel 75 (FIG. 6) runs freely in this direction without the transmission having to follow it.
  • the operation switch 93 is pressed.
  • the contactor 90 is activated via the control circuit 92. This attracts and via the overcurrent switch 91, the motor 52 is set in motion. It drives the shaft 55 (FIG. 2) via the planetary gear 54 and thus the pinion 56 in the first, lower gear stage 50 (FIG. 3).

  • the rope is held taut by the Dihol worn 22 at its expiring end, so that it lays firmly around the winch drum and the rope is obtained with considerable tensile forces.
  • the size of this force depends on the one hand, how often the rope is placed around the winch drum and on the other hand limited by the pulling force of the engine. However, this can be so great because of the engine characteristics that a risk to the Rope or tightly fetched good (sail) could exist if the control button is not released in time. In this case, even in the case of complete blockage, but the motor takes on such a high current that the overcurrent switch 91 triggers and stops the engine. The tension of the rope is maintained. In the case of a permanent engine overload, a thermal motor protection in the form of a bimetallic switch is provided in the motor 52.
  • the motor gear train does not need to be rotated, since with stationary or slower rotating engine Freewheel 64 when driving the hub 62 in the counterclockwise direction, the gear 60 free run.
