Gearbox main and auxiliary shaft assembly with lubricating and cooling structures

Abstract

The invention discloses a gearbox main and auxiliary shaft assembly with lubricating and cooling structures. The gearbox main and auxiliary shaft assembly comprises a gearbox box body, a lubricating and cleaning structure and the cooling structure. The lubricating structure is arranged at the upper end of the gearbox box body, an oil storage box is mounted at the lower end of the gearbox box body,the outer side of the oil storage box is connected with an oil guide pipe, a first bevel gear and a second bevel gear are mounted in the gearbox box body, the first bevel gear is located on the outerside of the second bevel gear, the middle position of the first bevel gear is connected with a transmission auxiliary shaft, and a transmission main shaft is mounted at the middle position of the second bevel gear. Through the arrangement of the cooling structure, lubricating oil can be conveniently cooled, when the bevel gears are lubricated through the lubricating oil, heat generated when the bevel gears are engaged can be fully absorbed, thus, the lubricating oil is cooled, and the effect of carrying out lubricating and cooling simultaneously can be achieved.

Description

technical field [0001] The invention relates to the technical field of gearbox devices, in particular to a main and auxiliary shaft assembly of a gearbox with a lubricating and cooling structure. Background technique [0002] The gearbox mainly refers to the gearbox of the car, which is divided into manual and automatic. The manual gearbox is mainly composed of gears and shafts, and the variable speed and torque are generated through different gear combinations; It is composed of torque converter, planetary gear, hydraulic pitch change system and hydraulic control system. Variable speed and torque are achieved through hydraulic transmission and gear combination. Lubrication is an important content of tribology research. It is a technical measure to improve the friction state of the friction pair to reduce the friction resistance and slow down the wear. Lubricants are generally used to achieve the purpose of lubrication. In addition, lubricants also have the functions of ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a gearbox main and auxiliary shaft assembly with a lubricating and cooling structure, which solves the problem that the traditional gearbox main and auxiliary shaft assemblies mostly use ordinary gears for transmission, and ordinary gears have large gear bearing capacity during transmission. Unstable transmission, large impact, easy to generate noise, and inconvenient lubrication, unable to reduce the internal transmission temperature of the gearbox. At the same time, it is not easy to deal with the metal debris generated by the impact of wear and tear between gears
