An upper bearing component and a guide rail system

Abstract

The invention discloses an upper bearing component and a guide rail system. The upper bearing component comprises an upper bearing substrate and an embedding plate, wherein the embedding plate is fixed on the upper bearing substrate and extends along the length direction of the upper bearing substrate; the outer side surface of the embedding plate is a contact surface for being contacted with the rolling surfaces of rolling bodies; the hardness of the embedding plate is more than or equal to 65HRC. The upper bearing component and the guide rail system provided by invention have the advantages that the design of adding the embedding plate on the upper bearing substrate is adopted, the hardness of the embedding plate is reasonably arranged, and the contact surface of the embedding plate is contacted with the rolling bodies, so that the conact area between the upper bearing substrate and the rolling body can be reduced, the service life of the upper bearing substrate is prolonged, the bearing capability also can be improved, the processing is also convenient, and the manufacturing cost is conveniently reduced; due to adoption of the design of concave parts and supporting shoulder parts, the friction force between the rolling bodies and an upper rolling track can be reduced, so that the circular resistance of the rolling bodies is reduced; since the design of arc-shaped end parts is adopted on a carrying plate, the rolling smoothness of the rolling bodies is improved, so that the reliability of operation of the guide rail system is improved.

Description

technical field [0001] The invention relates to an upper bearing assembly and a guide rail system. Background technique [0002] At present, the upper bearing plate is often combined with the base, the lower bearing plate, the moving guide rail, and multiple rolling elements to form a guide rail system. Specifically, the lower bearing plate is fixed on the base, the upper bearing plate is located above the lower bearing plate and can slide along the length direction of the lower bearing plate, and a lower mounting groove is formed between the upper bearing plate and the lower bearing plate; The moving guide rail is fixed on the upper bearing plate, and an upper mounting groove is formed between the groove portion of the moving guide rail and the upper bearing plate, and the upper mounting groove communicates with the lower mounting groove to form a closed annular cavity, and the plurality of rolling elements are arranged in on the ring cavity. While the moving guide rail a...

Problems solved by technology

like figure 1 As shown, the existing upper bearing plate is integrally processed with bearing steel with a lower hardness (hardness lower than 63HRC), resulting in a shorter service life of the upper bearing plate
