Shock absorption gear assembly

Abstract

The invention provides a shock absorption gear assembly, which comprises a first gear and a second gear with the identical tooth profile parameters, wherein the first gear is a driving gear, the second gear is coaxially arranged at the outer side of the first gear through a connecting element, one end of the connecting element matched with the second gear is provided with a rubber coating, and in the initial positions of the first gear and the second gear, the gear tooth symmetric centerline of the first gear and the gear tooth symmetric centerline of the second gear form an acute angle alpha, so a crankshaft gear of an output torque can be enabled to firstly drive the first gear to rotate, after the first gear rotates for the acute angle alpha, the tooth profiles of the first gear and the second gear are coincident, and in the process, the rubber coating can effectively buffer the impact force during the gear contact, so the vibration and the noise during the gear transmission are reduced, the gear abrasion is retarded, the service life of the gear is prolonged, and the engine quality is improved.

Description

technical field [0001] The invention relates to a damping gear assembly, which belongs to the technical field of auto parts. Background technique [0002] Gears are wheel-shaped mechanical parts that transmit torque by the meshing of teeth. The gear can achieve functions such as changing the speed and torque, changing the direction of motion, and changing the form of motion through transmission with other toothed mechanical parts (such as another gear, rack, and worm). Due to the advantages of high transmission efficiency, accurate transmission ratio, and large power range, gear mechanisms are widely used in industrial products, and their design and manufacturing levels directly affect the quality of industrial products. [0003] The noise of engine gear transmission is one of the main sources of engine noise. At present, gears are generally made of steel. The torque of the engine is basically transmitted through the gear train. There will be impact, and because both are ...

AI Technical Summary

Problems solved by technology

At present, gears are generally made of steel. The torque of the engine is basically transmitted through the gear train. There will be impact, and because both are made of steel, especially when the engine speed changes, this impact will produce a lot of vibration and noise, which will lead to increased engine noise and wear of gear parts, shortening the engine speed. lifespan, which is the shortcoming of existing technology
