Abstract
The utility model relates to a solid lubricative axle sleeve which takes an aluminium plate, a bronze plate, or a copper-steel sintered plate as a substrate. One surface of the utility model is provided with a shallow blind hole arranged regularly; the mixture of graphite, resin, non-ferrous metal powder is inlaid in the blind hole. Plate forms a round tube shape finally through drying, solidifying, sintering, and rolling, and the face of the blind hole towards inward. Every index of a bearing is better than a copper sleeve, and the utility model has the advantages of lubricating with no oil, and low noise.
Description
The utility model belongs to engineering element or parts in International Classification of Patents; For producing and keep the general measure of machine or effective operation of apparatus.Particularly roll formula solid lubrication axle sleeve.
General now axle sleeve is a copper sheathing, and lubricant oil infiltrates between copper sheathing and axle, forms oil film.But in the high capacity slow-speed of revolution, to-and-fro motion, oscillating motion and start under the frequent operating mode, still can produce and sting a phenomenon.
The purpose of this utility model is that design provides a kind of solid lubrication axle sleeve, and it does not sting axle, oil-free lubrication.
Scheme is as follows:
The solid lubrication axle sleeve is a matrix with aluminium sheet, bronze sheet or copper steel sintered plate, the one side of matrix has more shallow and regularly arranged blind hole, and blind hole is embedded with the mixture of graphite, resin, nonferrous metal powder, and is cylindrical through rolling, matrix is at skin, and blind hole is at internal layer.
Press the sample of such scheme trial-production, through the detection of legal detection department, every index all is better than copper sheathing, needn't refuel simultaneously, and noise is little.
Fig. 1 is one of the utility model embodiment's a plan view (broken section); Fig. 2 is the left view (broken section) of Fig. 1.
Below in conjunction with accompanying drawing, embodiment is described.
The solid lubrication axle sleeve is a matrix 1 with aluminium sheet, bronze sheet or copper steel sintered plate, and it simultaneously has more shallow and regularly arranged blind hole, and blind hole is embedded with the mixture 2 of graphite, resin, nonferrous metal powder composition.Sheet material drying, curing, sintering, roll, finally cylindrical, matrix 1 is at skin, the blind hole face just mixture 2 at internal layer.
Set blind hole diamondwise, circle or other shape, axially determining deviation is arranged, and interlacing is staggered; Also can arrange by oblique determining deviation.General matrix 1 thick 1 to 4 millimeter, dark 0.5 to 1 millimeter of blind hole.The 20-30% that blind hole area sum accounts for matrix 1 area is degree, surpasses the influence of upper lower limit value, is not very big.
Claims (3)
1, a kind of solid lubrication axle sleeve is characterized in that with aluminium sheet, bronze sheet or copper steel sintered plate be matrix [1], and the one side of matrix [1] has more shallow and regularly arranged blind hole, and blind hole is embedded with graphite, resin, nonferrous metal powder mixture [2]; Roll the back and cylindrical, matrix [1] is at skin, and the blind hole face is at internal layer.
2, solid lubrication axle sleeve as claimed in claim 1 is characterized in that blind hole is 0.5 to 1 millimeter deeply, and the blind hole mouth assumes diamond in shape or be circular, and oblique determining deviation is arranged, and interlacing is staggered.
