Flexible shock-absorption and noise-reduction gear

Abstract

The invention provides a flexible shock-absorption and noise-reduction gear. The flexible shock-absorption and noise-reduction gear comprises a gear body, a rubber shock-absorption disc and a twisting press disc, wherein the rubber shock-absorption disc is arranged between the gear body and the twisting press disc and is respectively fixedly connected with the gear body and the twisting press disc, and power or torque is input through the twisting press disc or the gear body, passes through the rubber shock-absorption disc and then is output through the gear body or the twisting press disc. The power or torque is output through the gear body or the twisting press disc after being subjected to the shock absorption and isolation action of the rubber shock-absorption disc, the design that the gear body and power input and output components are separated is adopted, the power or torque input and output components are separated, and the flexible shock-absorption and noise-reduction gear has good noise-reduction and shock-absorption functions, is obvious in effect of twisting vibration noise reduction, and improves transmission stability.

Description

technical field [0001] The invention belongs to the field of mechanical transmission, and relates to a gear structure, in particular to a flexible vibration-damping and noise-reducing gear. Background technique [0002] With the improvement of everyone's awareness of environmental protection, the vibration of mechanical equipment and the comfort of use have become one of the important indicators for evaluating its performance. Vibration and impact not only cause loud noise, but also seriously affect the safety and service life of equipment. In the field of mechanical transmission, gears are widely used in various transmission equipment, such as transmissions, reducers and other equipment, which use a large number of gear systems. Designing a gear structure that can reduce vibration, shock and noise during gear transmission is extremely important for low-noise quality equipment. [0003] At present, most of the gears are mostly one-piece structure, which is directly processe...

AI Technical Summary

Problems solved by technology

[0003] At present, most of the gears are mostly one-piece structure, which is directly processed from steel or billet, and is rigidly connected with the transmission shaft. The gear system has small damping, and the gear itself has vibration (such as gear knocking or torsional vibration) during the transmission process. The vibration energy cannot be consumed by itself, and there is a large shock and vibration when accelerating or decelerating.

[0004] The patent of Chinese patent "ZL200920161428.9" provides a kind of vibration reduction and noise reduction gear. In this patent, an annular groove is set on the gear body. The elimination effect of vibration is not obvious; the patent of Chinese patent "ZL200810088009.7" provides a low-noise gear, which is provided with damping rubber on both sides of the gear spokes, and the gear damping rubber cannot absorb and reduce or isolate the torsional vibration of the gear; China The patent "ZL200720187833.9" provides a vibration-damping gear. The gear body consists of an outer ring and an inner gear ring. The inner and outer rings are provided with grooves, and the grooves are equipped with vibration-damping springs. The gear can reduce vibration and noise. Effect, can consume the energy of torsional vibration, but its processing and assembly is complicated, the service life and bearing capacity of the spring are limited
