Abstract
The invention discloses a multi-layered composite wear resistant automobile balancing bearing and a manufacturing technique thereof. The multi-layered composite wear resistant automobile balancing bearing is good in wear resistance, long in service life and low in manufacturing cost. The multi-layered composite wear resistant automobile balancing bearing comprises a cylindrical base body, and is characterized in that the base body is a low carbon steel precision pipe; a wear resistant layer is arranged at the inner circumference of the base body and is composed of a steel plate, sintered copper powder on the surface of the steel plate and a teflon layer; the thickness of the sintered copper powder is 0.3-0.5mm; the thickness of the teflon layer is 0.2-0.3mm; pores are formed in the surface of the sintered copper powder and the porosity is 20%-30%. The manufacturing technique comprises the following steps: finely machining inner holes in the low carbon steel precision pipe; pressing sleeve; machining an outer circle and chamfering on two end surfaces, wherein the copper powder contains 5% of tin, 5% of zinc and 5% of lead and the sintering thickness is 0.5mm. The manufacturing technique is suitable for manufacturing the automobile balancing bearing.
Description
Technical field
The present invention relates to a kind of automobile component, relate in particular to a kind of MULTILAYER COMPOSITE wear resistant automobile equalizer bearing and production technology thereof for automobile suspension system.
Background technique
Bearing works to fix and reduce load friction factor in mechanical-force-transmission process, bearing can not only bear the load of axle, and there is the effect of anti-attrition and vibration damping, and for the equalizer bearing using in heavy-load automobile, because vehicle capacity is large, road conditions are complicated, work under hard conditions, thereby the power acting on balance shaft bearing not only has axial force, radial force, and also have various composite force and impact force, especially common equalizer bearing lubricating condition is poor, during work, friction factor is large, bearing inner wall easily weares and teares, thereby cause balance shaft bearing frequent breakage, in addition because the equalizer bearing size of applying on heavy-load automobile is relatively large, and material generally adopts Cuprum alloy, thereby causes manufacture cost higher.
Summary of the invention
The technical problem to be solved in the present invention is to provide that a kind of wear-resisting property is good, long service life, manufacture cost are economized MULTILAYER COMPOSITE wear resistant automobile equalizer bearing and production technology thereof.
In order to solve the problems of the technologies described above, the present invention is achieved through the following technical solutions:
MULTILAYER COMPOSITE wear resistant automobile equalizer bearing of the present invention comprises cylindrical base, described matrix is the accurate pipe of low carbon steel, in described matrix, week be provided with wearing layer, described wearing layer is comprised of sintered copper powder and the polytetrafluoroethylene floor on steel plate and surface thereof, the thickness of described sintered copper powder is 0.3～0.5mm, the thickness of described polytetrafluoroethylene floor is 0.2～0.3mm, and described sintered copper powder surface is provided with hole, and described porosity ratio is 20～30%.
As preferably, the porosity ratio on described sintered copper powder surface is 20%.
As preferably, the porosity ratio on described sintered copper powder surface is 25%.
As preferably, the porosity ratio on described sintered copper powder surface is 30%.
The production technology of MULTILAYER COMPOSITE wear resistant automobile equalizer bearing of the present invention is as follows:
(1) get the accurate pipe of low carbon steel;
(2) finish turning endoporus;
(3) gland; Get 08F steel plate, to its surface through copper powder sintering, the THICKNESS CONTROL of sintered copper powder is at 0.3～0.5mm, Copper Powder Surface porosity ratio is controlled at 20～30%, again teflon paving upside down firing knot is carried out in sintered copper powder surface, the THICKNESS CONTROL of polytetrafluoroethylene floor, at 0.3～0.3mm, is finally carried out trimming and full circle;
(4) finish turning wearing layer endoporus;
(5) cylindrical turning;
