Single-slot self-lubricating oscillating bearing with outer ring provided with composite lining plates and manufacturing method thereof

Abstract

The invention discloses a single-slot self-lubricating oscillating bearing with an outer ring provided with composite lining plates and a manufacturing method thereof. The single-slot self-lubricating oscillating bearing has the advantages of simple structure, low cost, good self-lubricating effect and strong bearing capacity and adopts the structure that at least four steel backing composite lining plates distributed radially along the circumference are adhered on the inner surface of the outer ring. The manufacture method comprises the steps of: processing the outer ring and an inner ring by using bearing steel, wherein the outer ring is provided with an axial seam; manufacturing the at least four steel backing composite lining plates coincident with the inner surface of the outer ring in shape after being spliced radially; hacking the surface of the steel backing of each steel backing composite lining plate, grooving the surface of the steel backing and carrying out running-in on a radial splicing surface; sequentially and radially splicing the steel backing composite lining plates tightly along the circumference direction by taking the axial seam of the outer ring as an initial point and adhering on the inner surface of the outer ring, heating and solidifying an adhering agent under the condition of applying external force on an adhering surface; and directly loading the inner ring into the outer ring.

Description

Technical field: [0001] The invention relates to a single-slit self-lubricating radial joint bearing and a manufacturing method thereof, in particular to a single-slit self-lubricating bearing with a composite liner in the outer ring with simple structure, low cost, good self-lubricating effect and strong bearing capacity Joint bearing and manufacturing method thereof. Background technique: [0002] At present, the known single-slit self-lubricating joint bearings have an outer ring and an inner ring. The inner surface of the outer ring is spherically matched with the outer surface of the inner ring. There is an axial slit on the outer ring. The lubrication methods of the sliding surface are usually as follows: Two forms: one is that the material of the outer ring is bearing steel, and the spherical surface of the inner ring is processed with a blind hole, and a solid lubricant is embedded in the blind hole, which is not only complicated in structure and troublesome in proce...

Problems solved by technology

However, since the outer ring of the single-slit self-lubricating spherical plain bearing is a 360-degree rotator except for the slit, the steel-backed composite liner bonded to the inner surface often falls off due to the deformation of the outer ring slit caused by the installation of the inner ring. For this reason, despite the stated advantages of steel-backed composite liners, they have not been applied to single-slit self-lubricating spherical plain bearings so far.
