Abstract
The utility model provides a self-lubricating bearing for an automotive brake. The self-lubricating bearing for the automotive brake comprises a cylindrical bearing body manufactured by using a rolling process, wherein the bearing body takes a good-quality carbon constructional steel plate as a base body; a spherical bronze powder layer is at least sintered on the upper face of the base body; a plastic working layer which takes a polytetrafluoroethylene material as a main material is further at least rolled and sintered on the spherical bronze powder layer, so as to form the bearing body at least made by the three layers of composite materials; an opening gap is arranged on the bearing body, and is made by the three layers of the composite materials, namely the base body, the spherical bronze powder layer and the plastic working layer; a combination face between the base body and the spherical bronze powder layer is at a molten state; the three layers of the composite materials are 1-2.5mm thick; and the spherical bronze powder layer is 0.20-0.35mm thick. The self-lubricating bearing for the automotive brake has the characteristics of good wear resistance, large bearing force, long service life, convenience in repairing and maintenance and the like.
Description
Technical field
The utility model relates to an automotive brake self oiling bearing, belong to a kind of technical field of bearings.
Background technique
The automotive brake self oiling bearing, it is a kind of upgrading regeneration product that is applied on automotive brake; The tradition name of this product is called " automotive brake axle sleeve ", is to adopt Cu alloy material to make, and due to the performance characteristics of material, it is lubricated that it in use must often add oiling agent, the guarantee normal operation, so troublesome maintenance, cost is high.In order effectively to address this problem, more domestic automotive brakes specialty factory is just from this automotive brake self oiling bearing of external import, but the present domestic similar automotive brake self oiling bearing that also do not have.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, can work under dry condition and provide a kind of, have that wear-resisting property is good, long service life, and have self-lubricating property and be convenient to the self oiling bearing that the automotive brake of maintaining is used, it can satisfy the needs of various automobiles frequently braking braking of break flexibility and reliability and various complex road surface operating modes in driving procedure.
The purpose of this utility model is completed by following scheme: it comprises a cylindrical bearing body of being made with rolling technology, it is matrix that this bearing support adopts carbon constructional steel plate, described substrates sintering at least has the spherical bronze bisque of one deck, also apply at least on this spherical bronze bisque roll and sintering one deck take teflon as main plastic working layer, and consist of a kind of bearing support of being made by 3-layer composite material at least.
Be provided with open seam on described bearing support, it is made by matrix, spherical bronze bisque and plastic working layer 3-layer composite material, the junction plane of described matrix and spherical bronze bisque is molten state, the thickness of described 3-layer composite material is 1-2.5mm, and wherein the thickness of spherical bronze bisque is 0.20-0.35mm.
The utility model is tested under DRY SLIDING, and load reaches 3.5N/mm
2, the friction factor during linear velocity 0.4m/s≤0.2, wear extent≤0.03mm, it is good that it has wear resistance, and bearing capacity is large, long service life and be convenient to the characteristics such as maintaining.
