Abstract

The utility model discloses a plum coupling type hoist which is capable of adapting to frequent starting, is good in elasticity and flexibility and small in shock. An output shaft of a motor is connected with an input shaft of a speed reducer through a plum coupler; the plum coupler is provided with a left semi-coupler and a right semi-coupler; a plurality of same bulge blocks are arranged on the shaft end parts of the left semi-coupler and the right semi-coupler; the bulge blocks are respectively, uniformly and rotationally distributed along the external edges of the shaft end parts of the left semi-coupler and the right semi-coupler by using the central axial lines of the left semi-coupler and the right semi-coupler as centers. According to the plum coupling type hoist provided by the utility model, as an elastic block is embedded in the gap which is formed by inserting the bulge blocks on the left semi-coupler and the right semi-coupler in an opposite way, the elastic block is radially squeezed to transfer torque, and the elasticity of the elastic block is utilized to compensate the opposite offset of the two shafts, so that the coupler can adapt to frequent forward and reverse starting better.

Description

A kind of plum blossom coupling type headstock gear

Technical field

The utility model relates to the headstock gear technical field, especially a kind of plum blossom coupling type headstock gear.

Background technology

In the technique known field, rolling open and close machine is to drive the device that reel, coiling rope are finished traction work by manpower or mechanical power, it can vertical-lift, level or inclination are dragged and drawn weight, existing generally based on motor-driven rolling open and close machine, rolling open and close machine have can adapt to certain lifting altitude, loading and unloading load big, can adapt to characteristics such as frequently keying, can be used for the situations such as opening and closing, lifting moving heavy object of gate.

In the use of reality, headstock gear need start or stop to realize the ascending, descending action of gate or goods frequently, corresponding with it, the drive motor of headstock gear and reductor also need to rotate frequently or stop, so just need bearing torque frequently, the coupler between the output shaft of drive motor and the input shaft of reductor changes, so coupler not only is very easy to owing to wearing and tearing cause damaging, the coupler flexibility of existing fixed formula is relatively poor simultaneously, causes the vibrations between the axial region also bigger.

The utility model content

The technical problems to be solved in the utility model is: provide a kind of and can adapt to that starting is frequent, elasticity and better flexible and shake less headstock gear.

The technical scheme that its technical matters that solves the utility model adopts is: a kind of plum blossom coupling type headstock gear, comprise the lifting frame, be provided with motor and speed reducer in described lifting frame, the output shaft of described motor links to each other with the input shaft of reductor by the plum blossom coupler, described plum blossom coupler has left half a coupler and right half a coupler, and described left half a coupler and right half a coupler are sheathed on respectively on the input shaft of the output shaft of motor and reductor, be equipped with a plurality of identical protruding blocks at described left half a coupler with shaft end on the right half a coupler, described protruding block centered by the central axis of left half a coupler and right half a coupler and respectively rotates distribution equably along the outward flange of the shaft end on left half a coupler and the right half a coupler, and form a plurality of mutual to inserting between the protruding block on left half a coupler and the right half a coupler, in plugging each other formed a plurality of gap, described protruding block all is inlaid with the Elastic Cylindrical piece, between described left half a coupler and right half a coupler, also be provided with annular resilient collar, the setting that is connected as a single entity of described annular resilient collar and Elastic Cylindrical piece.

Further, as a kind of concrete manifestation, all have four protruding blocks on left half a coupler described in the utility model and the right half a coupler, four protruding blocks on described left half a coupler and the right half a coupler form eight gaps to inserting the back, all are inlaid with the Elastic Cylindrical piece in described eight gaps.

The beneficial effects of the utility model are: the utility model is by inlaying elastomer block at the protruding block on left half a coupler and the right half a coupler to inserting between the formed gap, bear radial compression to transmit moment of torsion by elastomer block, utilize the elastic compensating diaxon relativity shift of elastomer block, make coupler can adapt to frequently forward and backward preferably and start, also make vibrations between the input shaft of the output shaft that greatly reduces motor and reductor.
