Embodiment Construction

[0030] Figure 1 and figure 2 Shown is a spherical bearing arrangement 1 comprising a bearing housing 2 in which a composite sphere 3 is mounted. The bearing seat 2 is substantially annular and comprises: a cylindrical outer surface 4 ; two axial end faces 5 ; and an inner surface comprising a spherical bearing seat support surface 6 . The bearing housing 2 also has a central axis 7 . The bearing seat 2 has a circumferential, radially extending flange 8 which approaches the axial end face 5 of the bearing seat 2 . The flange 8 has three equally spaced lugs 9 each protruding from the flange 8 . Each equally spaced lug 9 is provided with a hole 10 through which a bolt or the like can pass to fix the bearing housing 2 to another object via the lug 9 .

[0031] The composite sphere 3 is substantially spherical in shape and is provided with: a spherical composite sphere bearing surface 11 ; two axial end faces 12 ; and a hole 13 with a central axis 14 . The combined ball bearing...

Abstract

A spherical bearing arrangement comprising: a bearing housing; a plurality of split-ball portions which are together arranged in the housing to produce a composite ball having a spherical bearing surface, the composite ball having a bore passing therethrough, the bore having a central axis; and a bushing secured in the bore of the composite ball. A method of assembling a spherical bearing arrangement is also disclosed.

Description

technical field [0001] The invention relates to a spherical bearing device and an assembly method thereof. Background technique [0002] Bearings in the field of spherical bearings, and indeed bearings in general, need to provide precisely designed bearing surfaces where tolerances must be strictly adhered to to ensure smooth and efficient operation of the bearing. As a result of securing these tolerances, the manufacturing costs of bearings, and especially spherical bearings, are often high. [0003] It is known to be difficult to fit a ball into a housing of a spherical bearing arrangement, since any method must render the bearing torque substantially zero. The conventional approach is to provide a separate ball and swage the bearing housing around the ball to hold the ball fixedly therein. However, it has been found difficult to ensure that the torque of the bearing is maintained within a predetermined range. [0004] Spherical bearings include a split-ball structure, ...
