A kind of automobile gearbox gear cleaning device

Abstract

The invention relates to the technical field of gear machining, in particular to a cleaning device for an automobile transmission gear. The cleaning device comprises a base, a vertical plate, a liquid cavity and an inclined plate. The inclined plate is arranged at the edge of the base, and inclines inwards; the vertical plate is arranged on the periphery of the base, and the liquid cavity is formed by the vertical plate and the inclined plate; and a fixed bolt is arranged at the upper end of the inclined plate, and the gear is arranged between the lower end of the fixed bolt and the inclined plate and inclines along the inclined plate to go deep into the liquid cavity. The base is provided with the liquid cavity and the inclined plate connected with the liquid cavity, the gear is fixed through the inclined plate, and the gear is cleaned through the liquid cavity, so that the cleaning effect is achieved; meanwhile, due to the immersed cleaning manner, the good oil contamination cleaning effect is achieved; and the cleaning device has the beneficial effects of being convenient to use, easy to operate, simple in structure, good in practicability and the like.

Description

technical field [0001] The invention relates to the technical field of gear processing, in particular to an automotive transmission gear cleaning device. Background technique [0002] Generally, gears with variable speed are collectively referred to as transmission gears. The commonly used material for transmission gears is forged steel. Transmission gears often work under conditions of high speed, high load, and constant alternation of speed and load. The speed change gears rely on their own structural dimensions. And the strength of the material to bear the external load, which requires the material to have high strength, toughness and wear resistance. Due to the complex shape of the transmission gear, high gear precision requirements, and good material method, the current manufacturing method of automobile transmission gears has the following technical problems: [0003] 1. The existing manufacturing methods of automobile gearbox gears are simple, the quality of the prod...

AI Technical Summary

Problems solved by technology

[0003] 1. The existing manufacturing methods of automobile gearbox gears are simple, the quality of the produced products is average, and the general service life is not long;

[0004] 2. At present, most automotive gearbox gear blanks are turned by ordinary lathes, and all turning processes cannot be completed in one clamping, and it is difficult to ensure the coaxiality of the inner hole and the side surface, as well as the verticality of the end surface and the hole axis;

[0005] 3. Most of the existing gears of automobile transmission gears are hobbed by ordinary hobbing machines, the machining accuracy is low, and the surface roughness does not meet the requirements;

[0006] 4. Most of the existing automobile gearbox gears use the solid carburizing method, which is low in cost, but takes too long, and the thickness of the carburized layer is relatively thin;

[0007] 5. Most of the existing automobile transmission gears only use the heat treatment method of quenching, the effect is average, and the gear life is not long

[0008] After the gear processing is completed, further cleaning is required. The cleaning effect directly affects the later practical effect and affects the effect of paint, etc., and the process is relatively complicated.
