Expansion sleeve type damping coupler

Abstract

The invention provides an expansion sleeve type damping coupler. The expansion sleeve type damping coupler is formed by sequentially arranging a left expansion sleeve, a damping elastic set and a right expansion sleeve. The inner end face of the left expansion sleeve and the inner end face of the right expansion sleeve extend in the axial direction to form two or more metal claws respectively. The metal claws are evenly distributed along the circumferential positions of the end faces. An axial gap is formed between every two adjacent metal claws. The damping elastic set comprises a rigid intermediate body and two soft intermediate bodies, wherein the two soft intermediate bodies are located on the two sides of the rigid intermediate body. The soft intermediate bodies are provided with a plurality of soft grooves in the circumferential direction, wherein the shape of the soft grooves is the same as that of the metal claws. The rigid intermediate body is provided with a plurality of rigid grooves in the circumferential direction, wherein the shape of the rigid grooves is the same as that of the metal claws. The metal claws on the end face of the left expansion sleeve and the metal claws on the end face of the right expansion sleeve are all inserted into the grooves in the intermediate bodies. The expansion sleeve type damping coupler has the advantages that due to the design of the rigid intermediate body and the two soft intermediate bodies, the radial pressure on a mounting shaft is reduced to the maximum degree, the damping effect is obvious, and hazards caused by resonance are effectively restrained.

Description

[0001] technical field [0002] The invention belongs to the technical field of couplings, in particular to an expansion sleeve type damping coupling. Background technique [0003] Couplings are mainly used for connection in mechanical transmission and are the main parts in mechanical transmission. It plays the role of connecting the driving shaft and the driven shaft to transmit motion and torque, and compensates for eccentricity, deflection, and axial displacement caused by manufacturing errors, installation deviation errors, deformation after loading, and temperature changes. [0004] The application number of patent document 1 is CN201320035990.3, which discloses a plum-blossom expansion sleeve type coupling, which is composed of two flange sleeves 7, two flange plates 8 and an elastic body 14, so that the coupling The coupling also has the double excellent performance of the expansion type and the plum blossom type coupling. [0005] The application number of patent...

AI Technical Summary

Problems solved by technology

[0006] Therefore, when the expansion sleeve type coupling in the prior art transmits a large torque, the coupling often adopts the plum blossom petal connection method, which has poor precision and Not able to withstand alternating loads and impact loads, easy to produce backlash; the intermediate body is designed as a rigid body, which has poor ability to absorb resonance and cannot suppress resonance; poor torsional rigidity, long response time, and cannot effectively absorb resonance, eccentricity, and deflection angle
