Coupling elastic block structure with stress release groove

Abstract

This utility model relates to a coupling elastic block structure with a stress relief groove, including a first coupling housing, a second coupling housing, and an elastic block assembly. The elastic block assembly includes a rubber block, a mating groove, a sleeve, anti-slip texture, a stress groove, a damping plate, a spring, and a lead screw. The mating groove is located in the middle of the rubber block. In this utility model, the elastic block assembly is fixed to the mating ring by mating with the rubber block, and the sleeve is inserted into the mating post for positioning and installation with the first and second coupling housings. During use, when the mating post generates stress on the sleeve, the sleeve will compress the spring backward through the damping plate, thus buffering the generated stress. After the operation is completed, the spring will rebound, causing the damping plate to return to its original position. At this time, the generated stress can be released in the stress groove, thereby effectively preventing stress from affecting the elastic block assembly, the first coupling housing, and the second coupling housing, and avoiding damage.

Description

Technical Field

[0001] This utility model relates to the field of coupling technology, and in particular to a coupling elastic block structure with stress relief groove. Background Technology

[0002] A coupling is a mechanical component that connects two shafts or a shaft and a rotating part to transmit motion and power. It can rotate synchronously during normal operation and provides protection when overloaded. Couplings are widely used in power transmission systems in the industrial field. The selection of a coupling should take into account parameters such as torque, speed, and tolerance for deviation.

[0003] Couplings can be classified into rigid couplings and flexible couplings according to their structure. Flexible couplings are equipped with elastic blocks, which are mechanical connection devices that compensate for shaft misalignment and buffer shocks. They are mainly used to solve the problems of vibration, impact and shaft deviation in the transmission system of mechanical equipment. However, the existing elastic blocks have certain inconveniences in use.

[0004] During operation, the elastic blocks in a flexible coupling will generate stress due to the force applied. If these residual stresses cannot be effectively released after the equipment stops working, they will accumulate over long-term use, leading to a series of problems: not only will the elasticity of the elastic blocks gradually decrease, weakening the original buffering and shock absorption effect of the coupling; it will also increase the contact friction between the elastic blocks and other components of the coupling (such as half couplings, hubs, etc.), causing accelerated wear of parts, and even loosening of the connection, ultimately significantly shortening the service life of the entire coupling and increasing the potential risks of equipment operation;

[0005] Therefore, we propose a coupling elastic block structure with stress relief groove. Utility Model Content

[0006] In the existing technology, the inability to effectively release stress not only leads to the gradual decay of the elastic performance of the elastic block itself, weakening the original buffering and shock absorption effect of the coupling, but also exacerbates the contact friction between it and other components of the coupling (such as half couplings, hubs, etc.), causing accelerated wear of parts, and even causing loosening of the connection, ultimately significantly shortening the service life of the entire coupling and increasing the potential risks of equipment operation. This utility model provides a coupling elastic block structure with stress relief groove.

[0007] The technical solution adopted by this utility model is: a coupling elastic block structure with stress relief groove, including a first coupling housing, a second coupling housing and an elastic block assembly. The elastic block assembly includes a rubber block, a mating groove, a sleeve, anti-slip texture, a stress groove, a damping carrier plate, a spring and a lead screw. The mating groove is disposed in the middle of the rubber block, the sleeve is disposed on the outer surfaces of both ends of the rubber block, the anti-slip texture is disposed on the inner wall of the mating groove, the stress groove is disposed inside the rubber block, the damping carrier plate is disposed in the middle of the stress groove, the spring is fixedly installed between the damping carrier plate and the stress groove, and the lead screw is fixedly installed on the lower outer surface of the sleeve.

[0008] Furthermore, both the first coupling housing and the second coupling housing have a mating ring and a mating post on one end of their outer surface, with the mating post located around the mating ring. Both the first coupling housing and the second coupling housing have a bushing fixedly connected to their other end of their outer surface, with a groove on the inner wall of the bushing and a fixing thread on the outer wall of the bushing.

[0009] Furthermore, the adhesive block and the mating groove are integrally formed, and the adhesive block and the stress groove are integrally formed.

[0010] Furthermore, the stress groove is movably connected to the damping plate via the spring, and the sleeve is threadedly connected to the damping plate via the lead screw.

[0011] Furthermore, the structure of the second coupling housing is the same as that of the first coupling housing, and both the first coupling housing and the second coupling housing are welded to the mating column.

[0012] Furthermore, the bushing and the slot are integrally formed, and the bushing and the mating ring are through-type.

[0013] The beneficial effects of this utility model are:

[0014] In this invention, the elastic block assembly is fixed to the coupling ring by adhesive blocks during use, and the sleeve is inserted into the coupling post for positioning and installation with the first coupling housing and the second coupling housing. During use, when the coupling post exerts stress on the sleeve, the sleeve will compress the spring backward through the damping plate, thus buffering the stress. After the operation is completed, the spring will rebound and reset the damping plate, releasing the stress in the stress groove. This effectively prevents the stress from affecting the elastic block assembly, the first coupling housing, and the second coupling housing, thus avoiding damage. Attached Figure Description

During use, when the docking post 5 generates stress on the sleeve 303, the sleeve 303 will compress the spring 307 backward through the damping plate 306, thereby buffering the stress generated by the spring 307. When the work is finished, the spring 307 will rebound to reset the damping plate 306. At this time, the generated stress can be released in the stress groove 305, thereby effectively avoiding the stress from affecting the elastic block assembly 3, the first coupling housing 1 and the second coupling housing 2, and preventing damage.
