查询词典 power station

The effect of the friction moment of bearings on performance is researched. The forming mechanic and influence factors of the friction moment of ball bearing are analyzed. Suitable clearness and groove radius of ball bearings are obtained by experiment and calculation. The relationship between starting moment of ball bearing and various lubricants is analyzed. The measure for reducing the starting moment of ball bearing is put forward, it is the theory basis and reference for ball bearing design of small power unit system.The system is an unstable system when the 24-station ball pen tip production machine is running because of various interferences. It is too hard to describe the system by linear method, so the nonlinear formulation must be used.
