The specific embodiment
Next with reference to Figure of description to a kind of manual hoist of the present utility model, explain below the work.
A kind of manual hoist of the present utility model, structure comprise handwheel 1, stop mechanism 18, hoisting mechanism and pressure rope mechanism 16, and the preceding friction disc of described handwheel and stop mechanism is one by bolted connection and is connected by steep-pitch thread with the back friction disc; The input shaft 10 of described handwheel and hoisting mechanism is connected by key, rotates by input shaft and drives reel 4 motions; Described pressure rope mechanism 16 is fixed on the forward and backward bearing.
Described stop mechanism comprises ratchet 2, back friction disc 11, ratchet 12, preceding friction disc 13; Friction disc and back friction disc before the arranged outside of described pawl-and-gearing.
Described hoisting mechanism comprises reel 4, Cycloidal Wheel 5, eccentric bushing 6; Be provided with the eccentric bushing and the Cycloidal Wheel of mutual matched together between the input shaft of described hoisting mechanism and the reel.Described Cycloidal Wheel connects reel by gear pin.
Transmission principle is shown in (Fig. 1): input shaft 10 and eccentric bushing 6 are together when center 0b cw turns round, Cycloidal Wheel 5 promptly revolves round the sun around center 0b together with eccentric bushing, because the antagonistic force of the bearing pin guide on the anchor shaft makes Cycloidal Wheel around itself center 0c rotation, and by the gear pin pin gear sleeve on the reel 4 its rotation constant speed is passed to reel.So reel just obtains the identical motion that turns to input shaft.Its speed ratio is: i=Zz/ (Zz-Zb)=Zz Zb-Cycloidal Wheel number of teeth Zz-pin wheel housing (reel).
Winch is that the output shaft of standard cycloid speed reducer is fixed, and former fixing pin wheel housing (this structure is a reel) changes output link into, so the integral structure of reductor can all be arranged on the inside of reel, makes structure very compact.
The action principle of drg (referring to Fig. 2): overlapping ratchet 12 in 11 sky of friction disc, back, back friction disc is contained on the input shaft 10 with key, preceding friction disc 13 combines as a whole with handwheel 1 usefulness screw, and with motion thread with the back friction disc be connected, when axial load rises the direction rotation, friction disc is pressed on the ratchet before and after moment on the hand wheel shaft forces down, and at this moment ratchet 2 can not stop ratchet to rotate.When article stop to rise, ratchet stops article to descend, at this moment the friction force of ratchet and two dishes are produced by article deadweight and screw action, load-carrying is descended, hand wheel shaft is rotated to descent direction, and at this moment spiral has the trend that the braking platen is unclamped, and the friction force between dish is reduced, article just can descend, and the speed of article decline always adapts with the speed of hand wheel shaft.
In use, rotation handwheel 1, because the effect of screw thread, friction disc 13 rotates before driving, and at this moment preceding friction disc 13, back friction disc 11 compress ratchet 12, and this moment, ratchet rotated, and ratchet is in the state of getting loose.When rotating handwheel 1, input shaft 10 drives eccentric bushings 6 and rotates, and eccentric bushing 6 drives Cycloidal Wheel 5 and rotates, and before and after anchor shaft 3, back anchor shaft 8 are fixed on before this moment on the bearing, because the mutual action of power, just drive reel 4 and does in the same way and rotatablely move.The handwheel 1 that stops operating, then the ratchet driving surface blocks the ratchet rotation, because weight gravity and screw thread rotation effect, the front and back friction disc compresses ratchet 12, realizes braking at any position.The backward rotation handwheel can be realized the decline of weight.
The built-in winch of cycloidal-pin wheel transmission is for importing, exporting in the same way, and built-in part mainly is the cycloidal-pin wheel reduction gear apparatus, and this mechanism mainly is applicable to the elevator part by manual hoisting 0-2 ton weight hoisting crane.The built-in winch of cycloidal-pin wheel transmission, have that compact conformation, volume are little, in light weight, long load-carrying capacity height of life-span, be convenient to plurality of advantages such as dismounting and maintenance, particularly internal hidden type structure has replaced traditional open architecture, adapts to the new trend of present world winch development.Add advanced person's brake equipment cleverly, the arbitrary aloft position of weight failure-free is stopped.Running part adopts Lubricating Grease for Speed Reducer lubricated, safeguards simple and convenient.
Above-described only is the preferred implementation of a kind of manual hoist of the utility model.Should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, all belong to the protection domain of a kind of manual hoist of the utility model.
