Embodiment 1

[0033] Such as figure 1 As shown, a self-lubricating roller bearing includes: bearing outer ring 1, bearing inner ring 2, cage 3 and self-lubricating roller 4; bearing outer ring 1 is coaxially installed inside bearing inner ring 2, bearing outer ring 1 A cage 3 is installed between the bearing inner ring 2 and a self-lubricating roller 4 is installed on the cage 3 .

[0034] Such as figure 2 As shown, the self-lubricating roller 4 is pasted with a self-lubricating liner 6 through an adhesive 5, and the shape of the self-lubricating roller 4 includes a cylinder or a cone. The self-lubricating liner 6 is made of fiber-reinforced resin polymer composite material, and the surface of the self-lubricating roller 4 is roughened by shot blasting. The self-lubricating liner is compounded by weaving one or more of PTFE fibers, aramid fibers, polyester fibers and glass fibers and impregnating phenolic, epoxy or polyimide resins. Textile textures of fiber-reinforced resin polymer com...

Embodiment 2

[0037] Embodiment 2 is a preferred example of Embodiment 1.

[0038] Such as figure 1 and figure 2 As shown, this embodiment includes bearing outer ring 1, bearing inner ring 2, cage 3 and self-lubricating roller 4, etc. Compared with traditional roller bearings, bearing outer ring 1, bearing inner ring 2 and cage 3, etc. Without special design and processing, after the surface of the self-lubricating roller 4 is roughened by shot peening, the self-lubricating liner 6 is bonded by the adhesive 5 .

[0039] The self-lubricating roller 4 is a cylinder or a cone, and the self-lubricating liner 6 is pasted to have a three-layer structure, which is the self-lubricating roller 4 body, the adhesive 5, and the self-lubricating liner 6 successively from the inside to the outside. The thickness of the self-lubricating liner 6 is usually 0.25mm-1.5mm.

[0040] The surface of the self-lubricating roller 4 does not need to be finely ground during processing, and it is sufficient to car...

Abstract

The invention provides a self-lubricating roller bearing and a machining method. The self-lubricating roller bearing comprises a bearing outer ring, a bearing inner ring, a retainer and a self-lubricating roller; the bearing inner ring is coaxially mounted on the inner side of the bearing outer ring; the retainer is mounted between the bearing outer ring and the bearing inner ring, and the self-lubricating roller is mounted on the retainer; and a self-lubricating gasket is adhered to the outer side of the self-lubricating roller. The self-lubricating liner is adhered to the surface of the self-lubricating roller, so that maintenance is avoided, oil or grease is not required to be added for lubrication, and the maintenance cost is reduced.

Description

technical field [0001] The invention relates to the technical field of roller bearings, in particular to a self-lubricating roller bearing and a processing method. Background technique [0002] Bearings are the basic components of modern industry. Its main function is to support the mechanical rotating body and obtain a low friction coefficient, thereby reducing the energy loss of equipment in transmission. Normally, roller bearings are composed of bearing outer ring, bearing inner ring, cage, rollers, grease, etc., which are separable bearings, and are very convenient to install and disassemble. Lubrication is a key link in its use. Insufficient lubrication will easily lead to bearing wear and energy loss, and reduce the service life of the bearing. However, excessive lubrication will not only cause waste of lubricating grease, but may also affect the normal use of the bearing. And usually, it is necessary to regularly add lubricating oil or grease to the bearing for maint...
