Linear guide, also known as line rail, slide rail, linear guide, linear slide, used for linear reciprocating motion occasions, has a higher load rating than linear bearings, while it can bear a certain amount of torque, can be realized in the case of high loads of high precision linear motion. In the mainland called linear guide, Taiwan generally called linear guide, linear slide.
Taiwan HIWIN linear guide role
Qiwei electromechanical on the role of silver linear guide movement is used to support and guide the moving parts, according to the direction of the given reciprocating linear motion. Depending on the nature of the friction, linear motion guide can be divided into sliding friction guide, rolling friction guide, elastic friction guide, fluid friction guide and other types. Linear bearings are mainly used in automated machinery than more, such as German imports of machine tools, bending machines, laser welding machines, etc., of course, linear bearings and linear axes are supporting the use of.
1, automatic centering ability
From the arc groove of the DF (45-°45)° combination, at the time of installation, that is, by the elastic deformation of the steel ball and the transfer of the contact point, even if the mounting surface of the more or less some deviation, but also can be absorbed by the internal line rail slider, resulting in automatic centering ability of the effect of the smooth movement of the high precision and stability.
2, interchangeable
Because of the strict control of manufacturing precision, linear guide size can be maintained at a certain level, and the slider has a keeper design to prevent the ball from falling off, so part of the series of precision with interchangeable, customers can order according to the needs of the guide or the slider, and can also be separated from storing rails and sliders in order to reduce storage space.
3. High rigidity in all directions
The use of four rows of circular grooves, with four rows of steel balls and other 45 degrees of the contact angle, so that the steel ball to achieve the ideal two-point contact structure, to withstand loads from the up and down, and left and right directions; when necessary, can be applied to improve the rigidity of the pre-pressure.
Taiwan on the silver working principle
Can be understood as a kind of rolling guide, is by the steel ball in the slider and the guide rail between the infinite rolling cycle, so that the load platform along the guide rail easy high-precision linear movement, and the friction coefficient will be reduced to one-fiftieth of the usual traditional sliding guide, can easily achieve a high degree of accuracy in positioning. The end system unit design between the slider and the guide rail makes the linear guide rail bear the loads of various directions such as up and down, left and right at the same time, and the patented reflux system and the simplified structural design make HIWIN's linear guide rail have a smoother and low-noise movement.
HIWIN linear guide applications
Linear guide is mainly used in semiconductor manufacturing equipment, surface grinding machines, EDM machines, high-speed handling devices, NC lathes, food machinery, medical machinery, woodworking machinery, laser welding machines, industrial robots and other automation equipment.
