Description
Technical Field
The utility model relates to an automobile gear, in particular to lubricated shock attenuation automobile gear.
Background
Gears are wheel-like mechanical parts that transmit torque by virtue of meshing of teeth. The gear can realize the functions of changing the rotating speed and the torque, changing the moving direction, changing the moving form and the like through being matched with other toothed mechanical parts (such as another gear, a rack and a worm). Because of the advantages of high transmission efficiency, accurate transmission ratio, large power range and the like, the gear mechanism is widely applied to industrial products, and the design and manufacturing level of the gear mechanism can directly influence the quality of the industrial products. Gears are the main basic transmission elements in the automobile industry, and the quality of the gears directly influences the noise, the stability and the service life of automobiles. Transmission gears are important components of automotive engines for changing the speed ratio of the engine crankshaft and the driveshaft. In the working process of the gear of the gearbox, power is transmitted through the contact of the tooth surfaces, and the two tooth surfaces roll and slide in the meshing contact process, so that larger pressure stress and friction force exist. The rotating speed of the existing gear is high, and when the gear teeth and the wheel rim are subjected to external acting force, the gear teeth are likely to break due to the fact that a common gear has no buffer area, and subsequent normal use is affected.
