Problems solved by technology

[0004] figure 1 The problem with the bearing assembly 1 is its assembly defect due to the adjustment force acting on the ball 3 in the direction parallel to the central axis of the bearing housing 2, hereinafter referred to as the axial force
As a result, although the bearing 1 is designed to facilitate the rotation of the ball 3 in the bearing housing 2, when the ball 3 rotates repeatedly below the threshold torque, due to the shearing of the raceway:elastomer and / or sleeve:elastomer interface , bearing 1 is easily damaged

Embodiment Construction

[0041] figure 2 The bearing assembly 10 includes a bearing housing 11 with a partially embedded and rotatably mounted ball 12 inside.

[0042] Preferably, the ball 12 is spherical. However, as noted below, the shape of the sphere 12 may alternatively be a spheroid. expressed in figure 2 The ball 12 of the bearing assembly 10 is a complete sphere. However, only the portion of the ball 12 that engages (ie contacts) the bearing housing 11 needs to be spherical. Therefore, the sphere 12 can be selected as an incomplete sphere or a spheroid, such as image 3 with 5 shown in .

[0043] To the ball 12 is attached a pair of arms 13 , each extending on opposite sides of the ball 12 in a direction away from the bearing housing 11 . Preferably, the ball 12 and the arm 13 are integral so as to form a single part. The arm 13 is used to mount the bearing assembly 10 on other components and may be provided with, for example, threads 26 or bores 27 .

[0044] The ball 12 can be att...

Abstract

A bearing assembly comprising a housing and a ball at least partially housed within the housing. The housing comprises a race having a concave bearing surface,a sleeve surrounding the race, and a resilient member disposed between the race and the sleeve. The surfaces of the race and sleeve adjacent the resilient member and the surfaces of the resilient member preferably include at least one pair of a co-operating protrusion and recess. Alternatively, or additionally, the surfaces of the race and the sleeve adjacent the resilient member have different curvatures.

Description

technical field [0001] The invention relates to a bearing assembly, in particular to a spherical bearing assembly. Background technique [0002] figure 1 Shown is a known type of spherical bearing 1 comprising a housing 2 and a ball 3 partially embedded in the housing 2 . The bearing housing 2 comprises a race 4 with a spherical bearing surface 7 , a sleeve 5 surrounding the race 4 , and an elastomer 6 placed and bonded between the race 4 and the sleeve 5 . The raceway 4 and the sleeve 5 are coaxially arranged according to the central axis of the bearing housing 2 . The ball 3 is mounted in the raceway 4 such that the ball 3 can freely rotate within the raceway 4 preventing any large translational movements. [0003] The elastic body 6 is used to absorb the radial displacement of the sphere 3 relative to the bearing housing 2 , so-called radial direction refers to a direction perpendicular to the central axis of the bearing housing 2 . Thus, the bearing assembly 1 is abl...
