No intermediate medium is used between the moving element and the fixing element of the linear guide rail, but rolling steel balls are used. Because rolling steel ball is suitable for high-speed movement, small friction coefficient and high sensitivity, it can meet the working requirements of moving parts, such as tool rest and carriage of machine tools. The basic function of the fixing element (guide rail) of the linear guide rail system is like a bearing ring, a support for installing steel balls, and the shape is V-shaped. The bracket covers the top and both sides of the guide rail. In order to support the working parts of the machine tool, a set of linear guide rails has at least four supports. For supporting large working parts, the number of supports can be more than four. When the working parts of the machine tool move, the steel balls circulate in the groove of the bracket, distributing the wear amount of the bracket to each steel ball, thus prolonging the service life of the linear guide rail. In order to eliminate the gap between the bracket and the guide rail, preload can improve the stability of the guide rail system and obtain preload. An oversize steel ball is installed between the guide rail and the bracket. The diameter tolerance of steel balls is 20 microns, and the steel balls are screened and classified in increments of 0.5 microns. The steel balls are respectively installed on guide rails. The magnitude of preload depends on the acting force on the steel balls. If the force acting on the steel ball is too large, the steel ball will be subjected to preload for too long, resulting in an increase in the movement resistance of the support. There is a problem of balancing effect. In order to improve the sensitivity of the system and reduce the motion resistance, the preload should be reduced accordingly. However, in order to improve the motion accuracy and the retention of accuracy, sufficient preload negative numbers are required, which are two contradictory aspects. If the working time is too long, the steel ball will begin to wear out, and the preload acting on the steel ball will begin to weaken, resulting in a decrease in the movement accuracy of the machine tool's working parts. If the initial accuracy is to be maintained, the guide rail bracket must be replaced or even the guide rail must be replaced. If the guide rail system has been preloaded. The accuracy of the system has been lost, and the only way is to replace the rolling elements. The guide rail system is designed to maximize the contact area between the fixed element and the moving element, which not only can improve the bearing capacity of the system, but also the system can bear the impact force generated by intermittent cutting or gravity cutting, which can spread the acting force widely and enlarge the bearing area.
