Description

Technical Field

[0001] The utility model relates to the technical field of bearing guide rails, and more specifically, to an auxiliary structure for preventing the separation of a bearing guide rail. Background Technique

[0002] A guide rail is a basic device used to control the moving direction, position, and angle of an object, and is usually composed of a guide rail itself and a guide rail slider (also called a guide rail sliding pair). Guide rails are mainly used in linear motion systems of various equipment and machines. A bearing is a part used to reduce the friction of mechanical equipment and is usually composed of an inner ring, an outer ring, rolling elements, and a cage.

[0003] After retrieval, a new type of guide rail bearing with the publication number of CN214274246U includes an outer bearing ring, an inner bearing ring, a plurality of steel balls, a cage, and a dust cover; the outer bearing ring is sleeved on the outside of the inner bearing ring, and annular guide rail grooves are provided on the circumferential surfaces of the outer bearing ring and the inner bearing ring facing each other, and the steel balls are arranged in the annular guide rail grooves; the cage is sleeved on the steel balls to separate the steel balls; clamping grooves are provided at both ends of the bearing, and the dust cover is clamped in the clamping grooves; the upper and lower end surfaces of the bearing are of equal size, the diameter of the upper and lower end surfaces is 30.81 mm, the height of the bearing is 11.00 mm, and the diameter of the steel balls is 5.556 mm; the front view direction of the outer bearing ring includes three straight lines, namely straight line segment A, straight line segment B, and straight line segment C; the radius of curvature of straight line segment A is 24.9, the radius of curvature of straight line segment B is 25.1, the radius of curvature of straight line segment C is 25.0, and the maximum difference in the radius of curvature is the radius of curvature of straight line segment B - the radius of curvature of straight line segment A = 25.1 - 24.9 = 0.2. The groove curvature is optimized and the bearing runs more smoothly.

[0004] For common bearing guide rails, during the process of the transmission seat sliding relative to the guide rail, due to the relatively simple structure of the transmission seat, displacement and deviation are likely to occur during the transmission process, affecting the accuracy of transmission. Therefore, we propose an auxiliary structure for preventing the separation of a bearing guide rail to solve the above existing problems. Content of the Utility Model
