Embodiment 1

[0023] like Figure 1-2 As shown, the split bearing cage includes a cylindrical cage body 1. The cage body 1 is circumferentially provided with a plurality of retaining grooves 11 extending along the axial direction of the cage body 1. The retaining grooves 11 are evenly arranged in the circumferential direction. And the holding grooves 11 are arranged parallel to the center line of the cage body 1. The cage body 1 is composed of at least two arc-shaped plates 2 distributed in the circumferential direction and made of rigid materials. The slot 21 extends axially on the shaped plate 2, and the slot width of the slot 21 gradually increases to the width of the slot bottom. The positioning protruding strips 22 are matched with the card grooves 21 on the board 2 , and two adjacent arc-shaped plates 2 are connected to each other through the positioning protruding strips 22 and the card grooves 21 . The cage body 1 is formed by snapping and splicing at least two arc-shaped plates 2 ...

Embodiment 2

[0027] like image 3 As shown in the figure, the structure, principle and implementation steps of this embodiment are similar to those of the first embodiment. The difference is that the cross-section of the positioning protruding strips 22 in this embodiment is a right-angled trapezoid, and the short parallel sides of the positioning protruding strips 22 are The ratio between the length of 221 , the length of the short parallel side 221 to the long parallel side 222 and the length of the long parallel side 222 is 1:0.5-1:1.5-2.

Abstract

The invention belongs to the technical field of auto parts, in particular to a split bearing cage. It solves the technical problems such as the difficulty in processing the existing bearing cage. It includes a cylindrical cage body, and the cage body is provided with a number of retaining grooves extending axially along the cage body. The cage body is composed of at least two arc-shaped plates distributed in the circumferential direction and made of rigid materials. One side of the arc-shaped plate has a slot extending axially along the arc-shaped plate, and the width of the slot from the notch to the bottom of the slot gradually increases, and the other side of the arc-shaped plate has a slot extending axially along the arc-shaped plate and corresponding The positioning convex strip matched with the card slot on the adjacent arc-shaped plate, and the two adjacent arc-shaped plates are connected to each other through the positioning convex strip and the card slot. The advantages are: simple structure, a plurality of arc-shaped plates joined together to form a cage reduces processing difficulty, good stability, firm connection, and no need to replace the entire cage if some parts are damaged, and the cost is low.

Description

technical field [0001] The invention belongs to the technical field of auto parts, and in particular relates to a split bearing cage. Background technique [0002] The cage is a bearing cage, also known as a bearing retainer, which refers to a bearing part that partially wraps all or part of the rolling body and moves with it to isolate the rolling body, usually guide the rolling body and keep it in the bearing. The main function of the cage is to separate the rolling elements, reduce the friction between the rolling elements and maintain the stability of the rolling elements, keep the distance between the rolling elements equal, and distribute the load evenly. Existing cages, such as needle roller bearing cages, are difficult to process and require multiple steps, such as rough turning and finishing, which are costly. After partial damage, the entire cage needs to be replaced, which undoubtedly results in a waste of resources. Huge waste. [0003] In order to solve the pr...
