Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0018] Such as figure 1 Shown is the structural representation of the present invention. It consists of outer ring 1, inner ring 2, roller 4 and triple seals on both sides. The triple seal device is composed of sealing ring 5, lock ring 6 and spring ring 7. The outer diameter of the outer ring 1 has a flange 3. There is a thread on the outer diameter of the other side relative to the flange; a gasket 8 and a lock nut 9 are installed on the thread of the outer diameter of the outer ring 1 .

[0019] A positioning groove 10 is designed at the thread of the outer diameter of the outer ring 1 for the positioning of the gasket 8, and the lock nut 9 is used to adjust the clearance of the bearing installation.

[0020] The raceway of the outer ring of the bearing, the rolling surface of the rolling elements, and the raceway of the inner ring are all...

Abstract

The invention relates to an oscillation bearing provided with a flange and a locking device. The oscillation bearing comprises an outer ring, an inner ring, rollers and triple sealing devices at the two sides. Each triple sealing device is composed of a sealing ring, a locking ring and a spring ring. The outer diameter of the outer ring is provided with a flange, and the outer diameter of the other side opposite to the flange is provided with a thread. A gasket and a locking nut are mounted at the thread position of the outer diameter of the outer ring. Compared with a standard bearing, by means of the oscillation bearing, the bearing assembling problem is well solved; the problem that a bearing in a separated type shell deforms and other problems are eliminated; by means of the integratedbearing design, the bearing weight is reduced, and the weight of a main machine is reduced; and in addition, the cost of an airplane and cost of the bearing are lowered.

Description

technical field [0001] The invention belongs to the field of bearing structure design, in particular to a swing bearing with a flange and a locking device. Background technique [0002] Due to the limited installation space, the swing bearings used in the aircraft body (flaps, slats, etc.) cannot use conventional methods for axial and radial limit. In addition, the maintenance-free issue of the bearings must also be considered. Therefore, there is an urgent need for a A special structural bearing to solve installation and maintenance problems. Contents of the invention [0003] The invention provides a swing bearing with a flange and a locking device to solve the problem of assembly of the swing bearing and the problem of deformation of the bearing in a separable housing. [0004] The technical solution adopted by the present invention to solve the technical problem is to provide a swing bearing with a flange and a locking device. It consists of outer ring, inner ring, r...
