Abstract
A self-lubricating bearing for an automobile door hinge mainly comprises a bearing body formed by adopting a high-quality carbon structure steel plate as a base body. A spherical bronze powder layer is sintered on the base body, and a lead-free plastic working layer consisting of polytef and fillers without lead is rolled and sintered on the spherical bronze powder layer, so that the lead-free bearing body with three layers of compounded materials is formed; and the combined surface between the base body and the spherical bronze powder layer is in a fusion state, and the spherical bronze powder layer is as thick as 0.20mm to 0.35mm, so that the tubular lead-free bearing body with a flange at one end is formed. The automobile door hinge has the advantages of self-lubricating property, maintenance free, low noise and good heat dissipation; in tests without lubricating conditions, the maximum PV value of the self-lubricating bearing can be above 50 N/mm2.m/3, so that the self-lubricating bearing is an ideal upgraded and updated product of an automobile door hinge bearing.
Description
Technical field
The utility model relates to a kind of self oiling bearing, particularly a kind of automotive door hinge self oiling bearing.
Background technique
Be applied in car and process (being commonly called as iron hinge) with steel plate the earliest, generally, when assembling, add lubricating grease with the door hinge on other automobile; In frequent using process; Just do not volatilize for a long time and done,, cause the matching gap of hinge and mandrel to enlarge along with the aggravation of wearing and tearing; Influenced the adaptation of automotive door, causing in the process of moving, car door noise occurs because of vibration.Also used the door hinge of sintered metal powder bearing afterwards, though use condition take a turn for the better to some extent, but still undesirable.So press for a kind of novel automotive door hinge; Not only can bearing radial force; Simultaneously can bear axial force, just bear the weight of vehicle door, for satisfying the needs that frequently open the door and close the door; Should have that PV value height, selflubricating, friction factor are little, good heat dissipation and long characteristics of life-span, become a kind of upgrading regeneration product of desirable automotive door hinge bearing.
Summary of the invention
The purpose of the utility model is to overcome the deficiency that existing technology exists, and provide that a kind of PV value height, selflubricating, friction factor are little, automotive door hinge self oiling bearing that good heat dissipation and life-span are grown.This self oiling bearing has been installed on the automotive door hinge, can have been realized the characteristics of selflubricating, non-maintaining, low noise, good heat dissipation, thereby reached the workmanship that improves automotive door hinge and the requirement in working life.
The purpose of the utility model is accomplished through following technological scheme: it mainly includes the bearing support that a usefulness quality carbon structural steel is processed as matrix; Described substrates sintering has spherical bronze bisque; On this sphere bronze bisque, also apply and roll and unleaded plastic working layer that sintering one deck is formed with teflon and lead-free packing, and constitute a kind of unleaded 3-layer composite material bearing support.
The junction plane of said matrix and spherical bronze bisque is molten state, and the thickness of the bronze bisque of described sphere is at 0.20mm～0.35mm, and processes the unleaded 3-layer composite material bearing support of tubulose that an end has rib.
The thickness of described 3-layer composite material is in 1mm～2.5mm scope, adopt known rolling technology and bearing flanging process process band shelves limit and with the bearing support of tube wall axially open seam.
The described product of the utility model has the characteristics of self-lubricating property, non-maintaining, low noise, good heat dissipation, under unlubricated condition, tests, and its limit PV value reaches 50N/mm
2.m/s more than, become a kind of upgrading regeneration product of desirable automotive door hinge bearing.
