How do I know the maximum static friction force of sliding rail?
The maximum static friction force of sliding rail is mainly composed of a slider to control, to guide the German Rexroth Rexroth as an example, the factory has designed the slider. Several models such as Rexroth slider standard type 1651-194-20 (gap 10um), R1651-114-20 (slider preload with 0.02C Rexroth (1651-124-20), slider preload with 0.08C Rexroth slider (Rexroth 1651-134-20), guide the pretightening force. With the 0.13C above Shenzhen Yuheng Trade Co. Ltd. has a lot of cash supply, can be achieved within 48 hours to the hands of customers. Welcome your calls
The simplest and most accurate way is to do an experiment. There are many ways you think about it. Calculation requires a lot of arguments.
You need to understand the definition of maximum static friction: the frictional force that occurs in static friction is called static friction. When the tangential force increases gradually, but the two object remains relatively static, the static friction increases with the increase of the tangential external force, but the increase of the static friction force can only reach a maximum. When the magnitude of the tangential force is greater than this maximum, the two object will slip from relative stillness into relative sliding. The maximum of the static friction force is called the maximum static friction force". This limit friction is expressed in terms of F maximum. The maximum static friction force is proportional to the positive pressure N between the contact surfaces of the two bodies:F0max = 0NThe maximum static friction force is expressed by f0max, and N is the positive pressure. The scale constant 0 is called the static friction coefficient. It is a numerical value without a unit. 0 is related to the material, smoothness, roughness and dry wet condition of the contact surface, but it is independent of the size of the contact surface.
