Embodiment Construction

[0012] The specific embodiment of the invention is described with reference to the accompanying drawings.

[0013] as attached Figure 4 , 5 As shown: it is composed of beams 3 and pockets 4, the pockets 4 are evenly distributed on the beam 3, and the pockets 4 basically maintain a spherical shape. The right half of the pocket 4 is a spherical arc, and the bottom of the left half is also a spherical arc, both of which are processed together, collectively called the spherical pocket 1. The upper part of the left half is a semi-cylindrical pocket 2 with an inclination angle, and the inclination angle α is equal to the contact angle of the bearing. Figure 4 Among them, point B is the intersection of semi-cylindrical arc pocket 2 and spherical pocket 1 (the lower part of the left half), point C is the intersection of spherical pocket 1 (right half) and the outer diameter of the cage, and point D is The intersection of the semi-cylindrical arc surface pocket 2 and the outer dia...

Abstract

A metal solid cage for angle contact ball bearings comprises a beam and small holes. The small holes are uniformly distributed on the beam. The right-half part of the small hole is a spherical hole. The lower part of the left-half part of the small holes is a spherical cambered surface and the upper part of the left-half part of the small holes is a half-cylindrical cambered surface hole with a titling angle equal to the contact angle of the bearing.

Description

technical field [0001] The invention belongs to a bearing cage, and mainly relates to a metal solid cage for angular contact ball bearings. Background technique [0002] There are three main types of metal solid cages commonly used in angular contact ball bearings: 1. figure 1 The cylindrical straight pocket cage shown; 2. As attached figure 2 The upper half of the spherical bottom cage shown is cylindrical; 3. As attached image 3 As shown, the cage beams and pockets are inclined cages at a certain angle. The first two cages are suitable for use in the case of external guidance or internal guidance, that is, a certain guiding gap is formed between the outer inner diameter or inner diameter of the ferrule and the outer diameter or inner diameter of the cage. The latter cage can also be guided by rolling elements in the case of spherical pocket bottoms. The three kinds of cages mentioned above do not really form the guiding way of rolling elements, and the guiding way is...
