Abstract

The invention relates to a preparation method of a bearing retainer with a cooling and wear-resistant structure for a robot, and belongs to the technical field of mechanical basic parts and manufacture. A first retainer body, a second retainer body and a group of inner hexagon countersunk head screws are included, the first retainer body and the second retainer body are each provided with a groupof roller pockets, the end face, close to the first retainer body, of the second retainer body is provided with a first boss, the outer wall of the first boss is provided with a group of pawls, one end, close to the first retainer body, of the second retainer body is provided with a first groove, the inner wall of the first groove is provided with a group of wedge-shaped grooves, the first boss isarranged in the first groove, and the group of pawls are clamped in the group of wedge-shaped grooves. According to the preparation method, the design of a split structure is adopted, so that the replacement of the retainer part is facilitated, the pawls and the wedge-shaped grooves are arranged for radial rotation, the first retainer body and the second retainer body form a structurally stable whole through the group of inner hexagon countersunk head screws, and the service life of a bearing is prolonged.

Description

technical field [0001] The invention belongs to the technical field of robots, and in particular relates to a method for preparing a bearing cage for a robot with a cooling and wear-resistant structure. Background technique [0002] As an important bearing part, the cage is used to separate the rolling elements at equal distances and evenly distribute them on the circumference of the raceway to prevent the rolling elements from colliding and rubbing against each other during operation. Guide and drive the rolling elements to roll on the correct raceway. Its manufacturing precision and quality directly affect the service life of the bearing. [0003] Spherical roller bearings have two rows of rollers, which mainly bear radial loads and can also bear axial loads in either direction. Two rows of symmetrical spherical rollers, the outer ring has a common spherical raceway, and the inner ring has two raceways inclined at an angle to the bearing axis, which has good self-alignin...
