Introduce the working principle and characteristics of linear sliding unit:
The linear sliding unit can be understood as a rolling guide, which is an infinite rolling cycle of steel balls between the slider and the guide rail, so that the load platform can easily move along the guide rail with high precision and linearity, and reduce the friction coefficient to the usual traditional sliding One fiftieth of the guidance can easily achieve high positioning accuracy. The design of the final unit between the slider and the guide rail allows the linear guide rail to withstand the load in all directions such as up, down, left and right. The patented recirculation system and simplified structure design make HIWIN's linear guide rail have smoother and lower noise movement.
Linear sliding unit features
(1) Self-aligning ability
The combination of DF (45- ° 45) ° from the arc groove, during installation, due to the elastic deformation of the steel ball and the transfer of the contact point, even if there is some deviation in the installation surface, it can be absorbed by the inside of the rail slider. Produce the effect of self-aligning ability and get high precision and stable smooth movement.
Due to strict control of manufacturing accuracy, the size of the linear sliding unit can be maintained within a certain level, and the slider has a retainer design to prevent the steel ball from falling off, so some series of accuracy are interchangeable, and customers can order guide rails as needed Or the slider can also store the guide rail and the slider separately to reduce the storage space.
(3) High rigidity in all directions
The use of four-row arc grooves, combined with a four-row steel ball and other 45-degree contact angle, allows the steel ball to reach the ideal two-point contact structure and can withstand the load from the up and down and left and right directions; when necessary, preload can be applied to improve rigidity.
