Abstract
A self-lubricating sliding bearing includes a bearing seat, a bearing bush and an outer shaft sleeve; an annular bearing bush is nested in an inner chamber of the bearing seat; a plurality of uniformly-distributed through holes which are perpendicular to the inner surface are arranged on the inner surface of the bearing bush; a ring of annular sealing ring positioning slots are provided on the inner wall of the bearing seat on the other side of the bearing bush; and a wear resistant sleeve in interference fit with a shaft journal is assembled on the shaft journal portion of a rotating shaft on the position of the outer shaft sleeve. The utility model has the beneficial effects that the bearing bush part adopts the Ni-Cr-W-MoS2-graphite-Fe alloy bearing bush; a plurality of uniformly-distributed through holes which are perpendicular to the surface are arranged on the inner surface of the bearing bush, thereby allowing to store the abrasive dusts, the bug dusts, and the lubricating oil, such that the bearing under a low friction coefficient is convenient to start at low speed and low temperature; a sealing structure disposed on the end part of the bearing prevents wearing due to abrasive particles such as the bug dusts or the like; and the sliding bearing with a good lubricating property is applied to the metallurgic heavy-duty machine equipment in the operation state of high temperature, low speed and heavy duty.
Description
Technical field
The utility model relates to the powder metallurgical sintering process technology, relates in particular to a kind of self-lubricating plain bearing.
Background technique
Generally speaking, the mechanical transmission middle (center) bearing of procedure for steel rolling in metallurgical industry, smelting equipment is operated in the rugged environment such as high temperature, impact, dust, and lubricant grease is all easily evaporations and make serious wear under hot environment.Component material requirements intensity such as the oil-less self-lubricating bearing that turns round under high temperature, high speed load, seal ring are good, self-lubricating property is good, corrosion-resistant, damping noise reduction, running-in characteristic are good, and general powder metallurgy sintered oil-containing bearing shell is difficult to satisfy above requirement because of intensity is low.For example, certain class sliding bearing applies lead, tin, Cuprum alloy antifriction layer at the bore area of acieral antifriction material matrix, can be worn pressure break very soon under the high temperature heavy load and loses efficacy; In addition in use,, can cause steel backing to contact, cause the badly damaged of axle journal matching surface with the direct of axle journal in case the antifriction layer is destroyed.In addition, a lot of self-lubricating plain bearings adopt and fill the composite lubricated filler rod of solid-liquid that is made of solid lubricant, liquid phase lubricant oil and anti-wear additive on the bearing shell skeleton, its bearing capacity height, greasy property are good, but be not suitable for high temperature condition, be subjected to that high-temperature baking, lubricated filler rod are easily dry and astringent, carbonization was lost efficacy the bearing length time.
The model utility content
At above defective, the purpose of this utility model provide a kind of high temperature resistant, friction factor is low, abrasion resistance properties good, can increase the service life, help the self-lubricating plain bearing of selflubricating, to solve many deficiencies of prior art.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of self-lubricating plain bearing, comprise bearing support, bearing shell and external axle sleeve, some even distributions are set for nested one annular bearing shell in the described bearing support inner chamber, described inner surface of bearing bush and perpendicular to the through hole of internal surface, external axle sleeve is installed in the bearing support end in this bearing shell outside.The seal ring locating slot of offering a circle annular on the bearing support inwall of described bearing shell opposite side is used to be provided with sealing configuration, the axle journal position assembling that is positioned at the rotating shaft of external axle sleeve position to the mill sleeve and with the axle journal interference fit.
The beneficial effect of self-lubricating plain bearing described in the utility model is: its bearing shell partly adopts Ni-Cr-W-MoS2-graphite-Fe alloy bearing shell to form, inner surface of bearing bush is provided with some equally distributed through holes perpendicular to the surface, stored abrasive dust, dust thereby both can hold, also can store lubricant oil, fat, so that the startup when low speed, low temperature reduces friction factor; By sealing configuration being set in the bearing end, can prevent the abrasive wear that dust etc. causes, also the location to axle system plays a key effect; Can be applicable to metallurgical heavy duty equipment in the running state that is in high temperature, low speed, heavy duty, the greasy property of bearing is preferable.

According to embodiment and accompanying drawing the utility model is described in further detail below.
Fig. 1 is the perspective view of the described self-lubricating plain bearing of the utility model embodiment;
Fig. 2 is the application state schematic representation of the described self-lubricating plain bearing of the utility model embodiment;
Fig. 3 is the bearing shell part schematic representation of the described self-lubricating plain bearing of the utility model embodiment.
Among the figure:
1, bearing support; 2, bearing shell; 3, external axle sleeve; 4, axis hole; 5, through hole; 6, seal ring locating slot.
Embodiment
As Figure 1-3, self-lubricating plain bearing described in the utility model, comprise bearing support 1, bearing shell 2 and external axle sleeve 3, nested one annular bearing shell 2 in described bearing support 1 inner chamber, this bearing shell 2 parts adopt Ni-Cr-W-MoS2-graphite-Fe alloy bearing shell to form, and described bearing shell 2 internal surfaces are provided with some even distributions and perpendicular to the through hole 5 of internal surface, stored abrasive dust, dust thereby both can hold, also can store lubricant oil, fat, so that the startup when low speed, low temperature reduces friction factor; The external axle sleeve 3 that has axis hole 4 is installed in bearing support 1 end in described bearing shell 2 outsides, offer the seal ring locating slot 6 of a circle annular on bearing support 1 inwall of these bearing shell 2 opposite sides and by sealing configuration being set in the bearing end, can prevent the abrasive wear that dust etc. causes, also the location to axle system plays a key effect.In addition, the axle journal position between rotating shaft and external axle sleeve 3 assembling by Bearing Steel forms to grind sleeve and with the axle journal interference fit.
