Embodiment Construction

[0021] Specific embodiments of the present invention are described with reference to the accompanying drawings.

[0022] as attached figure 2 to attach Image 6 Shown: the double row ball bearing of the present invention, comprises outer ring 1, inner ring 2, steel ball 3, cage 4.

[0023] The outer ring 1 is a circular ring structure, the cross-sectional shape of the raceway is "M" shape, and has a three-curvature raceway, respectively, the curvature of the left channel is 1.1, the curvature of the middle channel is 1.3, and the curvature of the right channel is 1.5. 1 The curvature of the left channel of the three curvatures is 1.1 and the curvature of the right channel is 1.5, which match the curvature of the steel ball 3, and the radius curvature ratio is 1.04~1.08. The ratio of the radius of the curvature 1.5 of the right channel is 1.3~1.37, the curvature of the left channel of the outer ring is 1.1, the curvature of the right channel is 1.5, respectively, and the cur...

Abstract

A two-row ball bearing comprises an outer ring, an inner ring, a steel ball and a retainer. The outer ring is of an annular structure, the section of a roller path is in an M shape, and the outer ring is provided with three-curvature roller paths which are the left side channel curvature, the middle channel curvature and the right side channel curvature. The inner ring is of an annular structure, a roller path is spherical, and the circle center of the roller path of the inner ring and the geometric center of the bearing are gathered into one point. The steel ball is made of bearing steel materials or ceramic materials. The retainer is of an annular structure, is made of nylon or brass, has two sheets and is assembled from the outer sides of the two end surfaces of the bearing. The two-row ball bearing applying the design scheme has the remarkable advantages of high rotating speed, capability of automatically adapting to static and dynamic centering errors, large inclination angle allowing and capability of bearing radial load and bidirectional axial load.

Description

technical field [0001] The invention relates to the technical field of bearings, and mainly relates to a double-row ball bearing. Background technique [0002] In double row ball bearings, self-aligning ball bearings are widely used. The parts include outer ring, inner ring, steel balls, cages, etc. The raceway of the outer ring is spherical, and the inner ring has double deep groove raceways. The cage is usually Made of stamped steel, nylon or brass, it allows self-aligning. Due to structural design constraints, the relative inclination of the inner and outer rings must not exceed 3 degrees, and the limit speed is relatively low. In applications where the relative inclination angle of the inner and outer rings exceeds 3 degrees and the speed requirement is higher, the application requirements cannot be met. Contents of the invention [0003] The object of the present invention is to provide a double row ball bearing, the ultimate relative inclination angle of the inner a...
