Factors affecting the service life of tractor track shoes
1.Soil abrasive particles and medium The aggravation of wear at each wear part of tractor track shoe is closely related to the characteristics of soil abrasive particles and medium conditions. According to the measurement of energy spectrum probe, the soil is widely distributed on the wear surface, especially in...

Wear types of tractor track shoes
Because the stress state of tractor track shoe is complex and the working conditions have a great influence, the damage of tractor track shoe is the result of the comprehensive action of several different wear types. In the microscopic analysis of the worn parts of tractor track shoes, the...

Micro analysis of tractor track shoe surface wear
The micro analysis of the worn surface of tractor track shoe is of great significance to study its wear characteristics and failure mechanism, reasonably select materials and treatment technology, and improve the service life of tractor track shoe. 1.Research methods Through investigation, the severely worn tractor track shoes were...

Working conditions and macroscopic failure analysis of tractor track shoes
The working conditions of tractor track shoes are relatively poor. The relative motion characteristics and tribological characteristics of the contact parts at the joint are very inconsistent. Therefore, its wear failure type is more complex than other parts such as plough birch, rake blade and so on. The service...

Field wear test of tractor track shoes
In recent years, the track shoe research group has conducted 21 joint loading tests in Guangdong (paddy field), Northeast China and Henan (dry field). Based on these results, we draw the thickness dimension change of the worn part of the track shoe( Δ 50) It is a comparative block...

Abrasive wear characteristics of tractor cast track shoes
The cast track shoe of tractor is the most easily worn part on tractor and bulldozer. Its working conditions are relatively poor. It often has to be in the open air and in direct contact with soil and gravel, and withstand certain stress effects such as impact, tension, extrusion...

Abrasive wear characteristics of tractor parts track shoe
Tractor parts track shoes are the largest number of easily worn parts on tractors and bulldozers. Its working conditions are relatively poor. It often has to be in the open air and in direct contact with soil and gravel, and withstand certain stress effects such as impact, tension, extrusion...

Prospect of finite element method for tractor gearbox shell casting
The finite element analysis and topology optimization design of tractor gearbox shell casting under static conditions are carried out. The shell structure load is simple and does not consider fatigue, durability, reliability and other multi-body dynamics design requirements. Therefore, the optimization results have great limitations: only static analysis and...

Performance verification of improved tractor gearbox shell casting
In order to ensure that the improved structure can meet the requirements of stiffness, strength and dynamic performance, it is necessary to conduct free modal analysis and static structural strength analysis on the tractor gearbox shell casting, and compare the results with the original structural results to test the...
