Radial spherical plain bearing structure and use method thereof

Abstract

The invention discloses a radial spherical plain bearing structure and a use method thereof. An eccentric adjusting sleeve of the radial spherical plain bearing structure is connected to the outer wall of an outer ring, the central axis of the outer wall of the eccentric adjusting sleeve does not coincide with the central axis of the inner wall of the eccentric adjusting sleeve, the central axis of the outer wall of the outer ring does not coincide with the central axis of the inner wall of the outer ring, the central axis of the outer wall of the outer ring coincides with the central axis of the inner wall of the eccentric adjusting sleeve, the central axis of the inner wall of an inner ring coincides with the central axis of the outer wall of the inner ring, when a first stopping part and a second stopping part are not in a stopping fit relationship, the eccentric adjusting sleeve can rotate relatively to the outer ring, and when the first stopping part and the second stopping part produce related stopping cooperation, the eccentric adjusting sleeve and the outer ring are stopped and fixed. The bearing structure can improve bearing aligning amount at a certain aligning dip angle, is free of reduction of width of the outer ring and guarantees a bearing capability. The central axes of the inner and outer walls of the inner ring and the inner wall of the outer ring coincide so that stability of rotation of the inner ring relative to the outer ring is guaranteed and cycloidal motion is not produced.

Description

technical field [0001] The invention relates to a centripetal joint bearing structure and a using method thereof. Background technique [0002] The radial spherical plain bearing is a kind of spherical sliding bearing, the center axis of the outer ring and the center axis of the inner ring are the same axis, and its typical feature is that it can bear heavy loads and has the ability of self-aligning. The self-aligning ability of radial spherical plain bearings is related to the inclination angle of the bearing, and the inclination angle of the bearing depends on the width of the outer ring of the bearing and the width of the inner ring of the bearing. Such as figure 1 As shown, the inner ring 1' is socketed in the outer ring 2', and the outer ring 2' is socketed in the bearing seat 3'. When the two bearings cooperate to fix the shaft 4', the bearing inclination angle is 2α, and its maximum adjustment The amount of heart is u. Under certain working conditions, limited by t...

AI Technical Summary

Problems solved by technology

Under certain working conditions, limited by the assembly space, the width of the inner ring is limited. In order to achieve the specified amount of alignment, the usual practice is to reduce the width of the outer ring. However, in this way, the bearing capacity of the bearing will be greatly reduced. Facilitate the use of bearings
