18 years of painstaking research carefully conceived 18 years

Platinum has four main technical parameters that roller cam, roller contact angle of the hardness of their careers, the depth of hardening of the ring and the contact angle of the rollers career hardness, the depth of hardening of the career maturity of these three parameters of the theoretical system, and the curve of roles still empty.

In contact with the arc of race Drawn Cup Needle Roller Bearing oval higher reports of ball raceway relevant, the rise of the raceway ring oval ball guidance, ideas and research results, and is graduate of the structural parameters of elliptical career, processing methods and error analysis of the systematic theoretical study. Then they had a written Qian Weichang complex characters of the “elasticity”, began learning the study of elasticity of knowledge, while the calculation, while research has reached the load elliptical arc professional career high load capacity that the conclusions. However, the rotational branch suffer more than the elastic part of toleration, but no way of experimental verification, the project has only very slowly.

Market to determine whether a product is the key to success. Developed over time, put the number of products Spherical Plain Bearing oval pivot for the market. But the market mechanism is imperfect monitoring, efforts to promote the product is not strong and a number of reasons, the direct result of the market reaction is very low, which greatly slowed the product in research.

Swing-power and technical cooperation, Anhui University, properties pan mechanical co-founder of the project team, the viability of the turntable theoretical calculations and experimental research. To use the advanced modern finite element method, model 010.20.200 elliptical swing down in the finite element model 253 280 420 448 nodes, and finally at the national High Performance Computing Center (Hefei) calculate – and pathturnover compared with circular swivel head, oval track transport capacity by 30% or more, more than double the increases in life expectancy.
