Abstract

The invention relates to an abrasion-resistant gear for a high-speed gear box. The abrasion-resistant gear comprises C, Cr, Si, Mn, Zn, Cu, Ag, Au, Pt, Ni, W, Mo, Nd, Ce, Eu, Lu, Ti, AlN, S, P, talc powder, magnesium oxide, tungsten carbide, montmorillonite and Fe. The abrasion-resistant gear for the high-speed gear box has the advantages that raw materials for the abrasion-resistant gear contain the Zn, the Ni and the W, and accordingly the heat resistance and the corrosion resistance of the gear can be improved.

Description

technical field [0001] The invention relates to a wear-resistant gear for a high-speed gearbox, belonging to the technical field of auto parts. Background technique [0002] The gearbox mainly refers to the gearbox of the car. It is divided into manual and automatic. The manual transmission is mainly composed of gears and shafts, and the variable speed and torque are generated through different gear combinations; while the automatic transmission AT is composed of a hydraulic torque converter, a planetary gear and a hydraulic control system. Variable speed and torque are achieved through hydraulic transmission and gear combination. However, whether it is a manual transmission or an automatic transmission, transmission gears are required. [0003] Transmission gears often work at high speeds, high loads, and constant alternation of speeds and loads. In addition to the normal wear and tear of the gears, the quality of the lubricating oil, poor lubrication conditions, imprope...
