Friction power consumption of stainless steel needle

The needle roller bearing clutch of special pin manufacturer is a new friction type overrunning clutch. Compared with the present overrunning clutch, it has high bearing capacity, long service life, reliable clamping spectrum, etc. it is very possible to develop and design products suitable for different fields according to its basic principle according to changing some variable values. In this paper, the basic principle of the clutch posture is introduced in detail, and the analysis of fitness movement and support condition is carried out. In this paper, the relevant basic theory of solid mechanics is used to carry out analytical scientific research on the output power consumption caused by the rolling friction of this clutch, which provides the basis for further analysis report and thermal analysis.

It is generally believed that the rolling friction torque of the special-shaped cotter pin is related to the surface roughness of the contact surface, the backward ductility, the adhesion effect and the differential protection drag. Songyuanqing stressed that when the surface roughness of the two pieces touching the surface is less than 1 μ m, there is no harm to the friction torque basically, so the production of special-shaped pin can ignore the harm of surface roughness. It is considered that the key of rolling friction torque in overrunning clutch is the backward ductility and adhesion effect, while the harm of backward external economic drag and plastic deformation is relatively small and can be ignored. Therefore, only the output power consumption caused by the backward ductility and adhesion effect is studied analytically and scientifically, and the harm of the surface roughness of the touch surface and the drag of differential protection is not noted
