Embodiment Construction

[0030] In order to make the above objects, features and advantages of the present invention more comprehensible, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0031] Such as Figure 4 and Figure 5 As shown, the joint bearing of the first embodiment of the present invention includes:

[0032] an inner ring 10 with an outer spherical surface;

[0033] The outer ring 20 is sleeved on the inner ring 10. The outer ring 20 has an inner spherical surface S1 slidingly fitted with the outer spherical surface of the inner ring 10 and annular end surfaces S2 located on both sides of the inner spherical surface S1 in the axial direction. The annular end surface S2 is provided with a ring An annular groove 200 on the axis of the outer ring 20 .

[0034] Such as Figure 6 As shown, in an application of the spherical plain bearing of this embodiment, the shaft 30 is located in the inner ring 10 and closel...

Abstract

A spherical plain bearing comprises an inner ring with an outer spherical surface and an outer ring which sleeves the inner ring. The outer ring has an inner spherical surface which is in sliding fit with the outer spherical surface of the inner ring and an annular end face which is axially positioned at two sides of the inner spherical surface. The annular end face is provided with a slot. With the application of the spherical plain bearing of the technical scheme, the purpose of reducing edge stress of the outer ring and a bearing pedestal without the use of additional sleeves. Costs are reduced, and the step of installing sleeves is also omitted.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to a spherical plain bearing (Spherical Plain Bearing). Background technique [0002] Joint bearings are mainly composed of an inner ring with an outer spherical surface and an outer ring with an inner spherical surface. Joint bearings are generally used for low-speed swing motion (that is, angular motion). Since the sliding surface is spherical, it can also perform tilting motion (that is, self-aligning motion) within a certain angle range. When the temperature is large, it can still work normally. Joint bearings can withstand large loads, so they are widely used in engineering hydraulic cylinders, forging machine tools, engineering machinery, automation equipment, automobile shock absorbers, water conservancy machinery and other industries. [0003] Such as figure 1 As shown, an existing spherical joint bearing includes: an inner ring 1 with an outer spherical surface; Such a...
