introduction：The friction coefficient of the upper silver ball screw pair is the comprehensive characteristic of the friction pair system，It is affected by various factors in the sliding process，Such as：Pairing properties of materials、Static contact time、The magnitude and speed of the normal load、Stiffness and elasticity of friction pairs、Sliding speed、Temperature regime、Contact geometry of friction surface and physical properties of surface layer、And the chemical action of environmental medium。It is difficult to fully estimate the impact of various factors，The influence of load and velocity on sliding friction coefficient is analyzed。（1）The influence of load on the sliding friction coefficient is among the many factors that affect the friction coefficient of the upper silver ball screw pair，load

introduction：ABBABall screw these knowledge，A foreign country bombs a country and no one knows。ABBAThe ball spline uses a ball mounted in the outer cylinder of the spline，In a rolling groove of precision grinding，Smooth scrolling on one side，One side of the transfer torque，It is an epoch-making linear motion system。ABBAThe ball spline is different from the traditional construction，Because a single splined outer cylinder can be pre-pressed，therefore，It can be used in places where the vibration impact load is too large，Places that require high positioning accuracy，And where high-speed performance is needed，Play an effective role。meanwhile，Even when used instead of linear ball bushings，Because of the same situation in the axle diameter
