Definitions

  • the invention relates to an adapter device, with which a motor, in particular an electric motor, can be flanged to a textile machine, wherein a shaft of the motor is connected to a shaft of the textile machine.
  • the electric motor In a conventional electric motor driven textile machine, such as a track, the electric motor is associated with a brake unit which acts on a shaft to decelerate it.
  • the brake In an interruption of regular operation, z. B. when a power failure occurs, the brake is disabled, so that by means of the brake unit whose associated shaft is braked.
  • the brake unit In the brake unit, a brake pad connected to the shaft between two brake shoes is arranged and the gap between the brake shoes and the brake pad must be set very accurately, so that on the one hand full braking effect is developed during braking and on the other hand after releasing the brake no friction between the brake shoes and Brake pad occurs.
  • An electromagnet of the brake unit to release the brake must be constantly energized so that the shaft can rotate.
  • the adapter system can be connected by a hydrodynamic coupling with a drive motor, wherein the adapter shaft is assigned a brake unit. Information on the mode of action and application of the brake are not made here.
  • the components are located in a multi-part housing in which the shaft is mounted.
  • this adapter system is not suitable for use in a textile machine due to its structurally complex and massive design.
  • the setting of the gap dimension of the brake unit is independent of the installation of the drive motor, the maintenance and accessibility of the brake unit is, however, complicated due to the structural design of the adapter system.
  • an adapter device is interposed with a brake unit for braking a textile machine between a rotatably mounted element of the textile machine and a shaft of a motor.
  • the rotatably mounted element of the textile machine is preferably a shaft, a gear, a drive wheel or the like.
  • the adapter device has an engine-side flange for flanging to the engine and a machine-side flange for flanging on to the textile machine.
  • the adapter device has both an adjustment function between the Engine and the textile machine as well as a braking function by the brake unit. For maintenance or replacement of the engine this is easily solved by the adapter device and z. B. replaced as a single component cost.
  • the brake unit To service the brake unit, this can be removed and serviced or replaced between the engine and the textile machine. It does not have the brake unit to be completely replaced with the engine and an adjustment of the brake unit after removal of the engine is not necessary. By contrast, the brake unit can be reset, for example, without this affecting the engine.
  • the textile machine can be operated in an unregulated manner by blocking the adapter shaft by means of the braking unit while the engine is replaced while the textile machine is running but unregulated or can be serviced.
  • the adapter flanges are connected to each other only by a web, so that an open construction is available that allows maintenance or adjustment work with built-adapter device. At the same time, the heat dissipation is promoted by radiation and convection.
  • the engine flange and / or the machine flange of the adapter device are exchangeable, a simple adaptation can be made when changing the textile machine or using a different engine type by changing the corresponding adapter flange, without it being absolutely necessary that the other components of the adapter device to be changed. For example, if a motor to be replaced by another engine with modified connection dimensions, so can be made simply and inexpensively by replacing the motor-side adapter flange with the matched to the other motor connection dimensions.
  • the adapter shaft has a brake shaft and a torsionally rigid compensation coupling.
  • the compensating coupling an axial misalignment between the motor shaft and a shaft of the textile machine is compensated, so that no deformation forces occur between the axes.
  • the adapter shaft may be formed integrally with a brake shaft portion and a compensating coupling portion or in two parts of a separate brake shaft and a separate compensating coupling, which are interconnected.
  • the braking force is transmitted in the direction of rotation, while a play of the brake pad between the brake discs or brake plates must not be set on both sides of the brake pad by the axial displaceability of the brake pad.
  • a brake disc can be stored according to the brake shaft, wherein then act plates or discs with brake pad laterally on the so-mounted brake disc.
  • the compensation coupling is arranged between the brake shaft or brake unit and the engine, then on the one hand the heat dissipation from the brake to the engine is reduced. On the other hand, during braking, the compensation clutch is not loaded by the flywheel of the textile machine, so that the compensation clutch only has to absorb the torques that the electric motor can develop.
  • a compensating coupling in which a plurality of axially spaced slots are provided perpendicular to the shaft axis, a compact and inexpensive compensation coupling is provided.
  • one or more of the slots are circumferentially angularly offset from each other.
  • the rotational movement can be coupled to a gear of the textile machine by means of the adapter device.
  • the coupling between the adapter shaft of the adapter device and the motor can then take place in any desired manner, for example with a compensating coupling or a clamping ring.
  • no drive pinion must be provided, which must be squeezed during maintenance of the electric motor of the motor shaft and then pressed again.
  • the use of a standard motor from a large series is facilitated because the electric motor does not have to be provided with a matched for the textile machine pinion.
  • Fig. 1 shows as a first embodiment of an adapter device 1 in an exploded view with a brake module 2 and a flanged to the adapter device 1 electric motor 3.
  • the adapter device 1 has a machine-side adapter flange 10 and a motor-side adapter flange 11, which are connected by stud bolts 12.
  • the machine-side adapter flange 10 is screwed with screws 13 on the stud bolts 12 and the motor-side adapter flange 11 by means of screws 14 on the opposite side of the stud bolts 12.
  • the adapter flange 10 is interchangeable and can thus be adapted to different flange dimensions of different machine types.
  • the motor-side adapter flange 11 is connected by screws 6 with a motor flange 4 of the electric motor 3.
  • the motor-side adapter flange 11 is also interchangeable, so that various types of electric motor can be provided only by replacing the adapter flange.
  • the brake module 2 has a brake module shaft 20, to which a driver 21 is screwed torsionally rigid by means of grub screws.
  • a cam or ring gear is formed on the outer circumference of the driver 21, a cam or ring gear is formed.
  • a brake pad 22 or Bremskerl push is formed on the inner circumference to the sprocket of the driver 21 complementary inner ring gear.
  • the brake pad 22 is slidable in the axial direction on the driver 21, while for braking a torsionally rigid coupling between the brake pad 22 and driver 21 is.
  • an electromagnet 24 of the brake module 2 is attached to the machine-side adapter flange 10.
  • spacers 25 the distance between the machine-side adapter flange 10 and the solenoid 24 is set.
  • the screws 26 are passed through a hole in the spacer bolt 25.
  • the spacer bolts 25 may be rigidly connected to the solenoid 24 or via a screw, so that an adjustment of the distance between the machine-side adapter flange 10 and electromagnets is made possible by screwing the spacer bolts on the electromagnet.
  • the standoffs 25 serve as a guide for a spring plate 23 which is pushed away by means of springs between the spring plate 23 and the electromagnet 24 of the latter. If the electromagnet 24 is energized by current, the spring plate 23 is attracted to the electromagnet. Between the spring plate 23 and the inner surface of the machine-side adapter flange 10, the brake lining 22 is arranged. When energized solenoid 24, ie when the spring plate 23 is attracted to the electromagnet, a clearance for the brake pad 22 is present between the spring plate 23 and adapter flange 10, so that it can rotate freely in the gap.
  • the brake module shaft 20 is sleeve-like design and slotted on the side of the electric motor 3, so that the brake module shaft 20 receives on the side of the electric motor 3, a motor shaft 5 of the electric motor.
  • the brake module shaft 20 is fixed by means of a clamping ring 30 fixed to the motor shaft 5.
  • a clamping ring 32 of a torsionally rigid compensation clutch 31 is pushed and connected torsionally rigid by clamping.
  • the torsionally stiff compensation clutch 31 is provided to compensate for an axial offset between a rotary shaft of the textile machine and the brake module shaft 20 and the electric motor 3.
  • a torsionally rigid coupling between a shaft of the textile machine and the compensating coupling 31 likewise takes place via a clamping ring 33.
  • the openings for the implementation of the brake module shaft 20 in the adapter flanges 10 and 11 and in the spring plate 23 and the electromagnet 24 have a play in the radial direction, so that an axial offset of the motor shaft 5 relative to the axis of symmetry of the flanges 10, 11 by radial displacement of the Brake module shaft 20 can be compensated within the adapter device 1.
  • the brake module shaft 20 or the compensating clutch 31 can be pulled out of the adapter device without further intervention.
  • the brake module 2 is directly connected exclusively to the machine-side adapter flange 10, only torques are transmitted to the machine-side adapter flange 10 when the flywheels of the machine are decelerated.
  • the motor-side adapter flange 11 is completely load-free, so that no torsional forces are transmitted to the electric motor 3.
  • the height of the stud bolts 12 is advantageously chosen so that a gap or air gap between the back of the electromagnet 24 and the motor-side adapter flange 11 is present. As a result, there is no direct heat transfer transition between the electromagnet 24 and adapter flange 11 or electric motor 3 and therefore no appreciable heat transfer from the electromagnet 24 to the electric motor 3.
  • the electric motor 3 can be exchanged without the need to change the Bremsspaltsammlung the brake module.
  • the adapter device 1 can be replaced, wherein the factory preset gap for the brake module when installing and removing does not need to be reset.
  • the torsionally rigid compensation clutch can be omitted or arranged between the brake module shaft 20 and the motor shaft 5. In this case, there is then a rigid coupling between the machine shaft and the brake module shaft 20.
  • the adapter device 1 can also be retrofitted in systems in which so far no deceleration was provided.
  • FIG. 2 shows a second embodiment of an adapter device 1 '.
  • a brake module shaft 40 is provided on the machine side with a pinion 41.
  • the pinion 41 is engaged with a gear of a textile machine, not shown, to drive them by means of the electric motor 3 or to regulate the speed of the textile machine.
  • the brake module shaft 40 is mounted in two bearings 42, 43, wherein the bearings 42, 43 are in turn mounted in a bearing bush 44 of a machine-side adapter flange 10 '.
  • the machine-side adapter flange 10 ' serves as a bearing flange for the brake module shaft 40.
  • a brake module 2 ' is modified relative to the brake module 2 of the first embodiment in that a brake plate 28 is arranged at a distance from the machine-side adapter flange 10'.
  • the brake plate acts on the spring plate 23 opposite to the brake pad 22 a.
  • the rotatably connected to the brake module shaft 40 driver 21 is spaced by a spacer ring 45 of the bearings 42, 43.
  • the spacer ring 45 serves to cover the bearings 42, 43 against contamination by brake abrasion and, conversely, protects the brake lining 22 against lubricant from the bearings 42, 43.
  • the torsionally rigid compensation clutch 31 is arranged between the motor shaft 5 and the motor-side end of the brake module shaft 40.
  • the clamping ring 32 is clamped for connection to the motor shaft 5 on this and the clamping ring 33 is clamped for connection to the brake module shaft 40 on the motor-side end.
