Tooth width is usually regarded as an effective measure to improve gear strength, but in the actual design process, when changing the tooth width, the parameters such as the quality of the gear system, the moment of inertia and the gear fit eccentricity will also change, and the change...
As the end of the gear transmission chain, the load of each accessory directly affects the strength, connection reliability, lubrication and other dynamic characteristics of the gear system. During the working process, affected by the working state and actual working demand, the load of the water pump, fuel injection...
The dynamic characteristics of the gear system mainly include gear strength, connection reliability, lubrication characteristics, etc. Among them, the gear strength is mainly evaluated by the dynamic inter-tooth force, the connection reliability is mainly evaluated by the radial force of the bushing, and the lubrication characteristics are mainly evaluated...

Reliability is one of the key points in the engine development process, and the reliability of gear system plays an important role in the engine reliability. The gear structure is complex, and the operating conditions are variable. There are many factors that affect the reliability of the gear system....
With the emergence of new technologies, the processing technology of parts requires higher efficiency, higher quality and higher accuracy. Therefore, it is difficult for typical mechanical processing technology to meet the new process requirements, especially for the emergence of new energy machinery and equipment to bring new challenges to...
The technological process represents the technological level of gear processing. It should be carried out according to the relevant standards in combination with the processing plan. Each process should be strictly controlled, and the operation should be carried out according to the operating standards to improve the processing safety....
The analysis of gear processing technology must be carried out before processing, including the working conditions of the gear, the function of the gear and the change of the load it bears. The corresponding process route should be formulated according to the actual situation of the gear service, and...
Automobile is one of the most important technological achievements in modern industry. The rapidly developing automobile industry and other related industries are pushing mankind to move towards a more civilized industrial kingdom. However, the use of a large number of cars has had a very significant impact on human...
The gear material was sampled, and its chemical composition was analyzed by three testing institutions. The chemical composition index was shown in Table 1. The American standard trademark 3310 was found in the domestic and foreign steel grade manuals. Inspection organization C Si Mn P S Cu Ni Cr...
