Linear guides are the main components of our machinery and an indispensable part of our machinery. They are used in almost all machinery industries. So how much do you know about our linear guides? Let us follow the editor to find out!
Linear guides can be divided into three types: roller linear guides, cylindrical linear guides, and ball linear guides. They are used to support and guide the moving parts and perform reciprocating linear motion in a given direction. Depending on the nature of friction, linear motion guides can be divided into sliding friction guides, rolling friction guides, elastic friction guides, fluid friction guides and other types.
effect:
The function of the linear guide motion is to support and guide the moving parts to make a reciprocating linear motion in a given direction. Depending on the nature of friction, linear motion guides can be divided into sliding friction guides, rolling friction guides, elastic friction guides, fluid friction guides and other types. Linear bearings are mainly used in automated machinery, such as machine tools imported from Germany, bending machines, laser welding machines, etc. Of course, linear bearings and linear shafts are matched. Linear guides are mainly used in mechanical structures that require relatively high precision. There is no intermediate medium between the moving elements and fixed elements of the linear guide, but rolling steel balls.
working principle:
It can be understood as a kind of rolling guide, in which the steel ball rolls infinitely between the slider and the guide rail, so that the load platform can easily move with high precision along the guide rail and reduce the friction coefficient to the usual traditional sliding guide. One-fiftieth, high positioning accuracy can be easily achieved. The design of the final unit between the slider and the guide rail enables the linear guide to bear the load in all directions, such as up, down, left, and right. The patented recirculation system and simplified structural design make the linear guide of the linear guide more smooth and low-noise movement.
Slider-the movement is transformed from a curve to a straight line. The new guide rail system enables the machine tool to obtain rapid feed speed. In the case of the same spindle speed, rapid feed is a characteristic of linear guides. Linear guides, like flat guides, have two basic elements; one as a guide is a fixed element, and the other is a moving element. Since the linear guide is a standard component, it is for machine tool manufacturers. The only thing to do is to process the plane of a mounting rail and adjust the parallelism of the rail. Of course, in order to ensure the accuracy of the machine tool, a small amount of scraping of the bed or column is essential. In most cases, the installation is relatively simple. The guide rail as the guide is hardened steel, which is placed on the installation plane after fine grinding. Compared with flat guide rails, the cross-sectional geometry of linear guide rails is more complicated than that of flat guide rails. The reason for the complexity is that grooves need to be machined on the guide rails to facilitate the movement of sliding elements. The shape and number of grooves depend on the machine tool to complete. Function. For example: a guide rail system that bears both linear force and subversive moment is compared with a guide rail that only bears linear force. The design is very different.
The basic function of the fixed element (guide rail) of the linear guide system is like a bearing ring, and the bracket for mounting the steel ball is shaped like a "v". The bracket wraps the top and both sides of the rail. In order to support the working parts of the machine tool, a set of linear guide has at least four supports. Used to support large working parts, the number of brackets can be more than four.
