Description

Technical Field

[0002] The arc rolling guide is a new type of rolling guide with an arc-shaped track. On this guide, the slider can realize circular motion along the guide. Multiple sections of arc track can be spliced ​​into a complete circular ring to realize the circular motion of the slider. During installation, it is necessary to ensure the radial position of each section of the track is accurate to ensure the accuracy of the motion. The current radial positioning structure usually includes multiple adjustment blocks symmetrically installed on both sides of the arc guide to enhance the radial positioning stiffness and strength of the track and reduce radial deformation under heavy loads. However, most of the radial positioning structures do not have a dustproof structure, which leads to dust and foreign matter easily invading the interior of the positioning structure in harsh working environments, accelerating the wear inside the components, thereby reducing the service life of the guide.
