Description
Technical Field
The utility model belongs to the technical field of mechanical transmission equipment or device, concretely relates to an elastic coupling for hoist.
Background
The elastic coupling is a common coupling device in the current coupling device, and especially along with the continuous popularization of intelligent manufacturing, intelligent control is a current development trend. The key to intelligent control is to obtain crane parameters, including motion component rotation parameters, such as encoders. The coupler has the advantages of being small in size, small in transmission torque, high in accuracy and capable of finding out that the coupler is high in coaxiality requirement due to the fact that the coupler is integrated in the coupler, the coupler is not convenient to mount and dismount due to the fact that the length of the coupler is fixed, mounting and maintaining efficiency is low, and when the crane is intelligently transformed, the coupler cannot accurately acquire rotating parameters of rotating parts due to the fact that coaxiality is difficult to guarantee. Meanwhile, the integral coupler is rigidly connected, so that external forces influencing the running stability of the coupler, such as axial play, radial run-out and the like generated in the running process of the coupler, lack effective elimination capability, and the service life of the connected rotating parameter acquiring device is seriously influenced.
Therefore, in order to meet the current situation, a new elastic coupling structure for a crane needs to be developed urgently to meet the actual use requirement.
Disclosure of Invention
The utility model aims to solve the technical problem that overcome above-mentioned prior art's shortcoming provides a simple structure, installs convenient, effectual axial float, the elastic coupling for hoist of the radial runout effort that alleviates the production among the power transmission process.
The technical scheme for solving the technical problems is as follows: the left transmission shaft is fixedly connected with the left shaft sleeve through a left positioning piece, the right transmission shaft is fixedly connected with the right shaft sleeve through a right positioning piece, a left groove is formed in one end of the left shaft sleeve, a right groove symmetrical to the left groove is formed in one end of the right shaft sleeve, and an elastic block is arranged between the left groove and the right groove.
The utility model discloses a central line of left side transmission shaft, the central line of right transmission shaft and the central line of elasticity piece are same straight line.
The utility model discloses a left setting element is the bolt.
The utility model discloses a right setting element is the bolt.
The utility model discloses an elastic block is polyurethane elastic block.
