Abstract
The utility model discloses a self-lubricating bearing and particularly relates to a high-bearing and high-wear-resistance multiple-layer sintering self-lubricating shaft type bearing and a plate type bearing. The high-bearing and high-wear-resistance multiple-layer sintering self-lubricating shaft type bearing comprises a steel sleeve or a steel plate; one layer of a porous sintering alloy lubricating layer is sintered on an inner hole face of the steel sleeve or one layer of the porous sintering alloy lubricating layer is sintered on a single face of the steel plate. According to the high-bearing and high-wear-resistance multiple-layer sintering self-lubricating shaft type bearing and the plate type bearing disclosed by the utility model, the technical disadvantages of poor bearing capability and poor wear resistance of an existing self-lubricating bearing are solved; the high-bearing and high-wear-resistance multiple-layer sintering self-lubricating shaft type bearing and the plate type bearing can be widely applied to mechanical shaft transmission parts including a guide plate and a guide sleeve of a car covering piece mould, a guide plate of a car meridian tire mould, a Green column guide sleeve of an injection molding machine, a joint connection shaft sleeve of an excavator oil cylinder and the like, and have the advantages of high bearing capability, strong wear resistance and small friction coefficient.
Description
Technical field
The utility model relates to a kind of self-lubricating bearing, and particularly the multiple layer of a kind of high-mechanic high abrasion sintering is from moistening shaft type bearing and board-like bearing.
Background technique
Need to rotate in many mechanisms, the position of turn, usually all bearing can be set, rotation with assisting agency is more smooth and easy, simultaneously can carry out spacing to mechanism, effect with support, just bearing can produce friction after long-time running, the phenomenon of heating, need filling lubricant oil or Lubricants to come lubrication assistant, it is smooth and easy to supply the bearing rotation to operate, and avoids bearing rotation heating, so bearing will proper functioning rotate, must there be the medium that provides lubricated to exist, general institute often use lubricant medium as water or lubricant oil, and in the bearing using process, need often to add additional, not only suitable trouble also causes staff's inconvenience.
A kind of self-lubricating bearing has appearred in the market, self-lubricating bearing is in operation process, provide lubricant medium outside need not, having solved above-mentioned plain bearing in use needs often to add the supplemental lubrication agent, and not only suitable trouble also causes the technology drawback of staff's inconvenience.But still there is tangible not enough point in it, it wherein the most significantly is exactly the multiple layer sintering sheet material that existing self-lubricating bearing adopts, be to roll certain thickness at milling train again by sintering earlier, such sheet material length can be extended, be rolled into cylindric again, can increase the compressive force of alloy-layer again, greatly influence the adhesive strength of alloy-layer and steel plate, thereby the bearing capacity of the self oiling bearing of making by above-mentioned material is poor.Also have, the alloy-layer material was made up of phosphor bronze in the past, and wear resistance is general, did not have from moistening antifriction function.
The model utility content
The purpose of this utility model is to provide a kind of bearing capacity height, the multiple layer of wear resistance is strong and friction factor is little high-mechanic high abrasion sintering from moistening shaft type bearing and board-like bearing in order to solve above-mentioned the deficiencies in the prior art.
To achieve these goals, the designed multiple layer of the high-mechanic high abrasion sintering of the utility model moistens the shaft type bearing certainly, comprises steel bushing, and sintering has one deck porous sintering alloy lubricating layer on the inner hole surface of described steel bushing.
Also provide the multiple layer of a kind of high-mechanic high abrasion sintering from damping formula bearing in the utility model, comprised steel plate, sintering has one deck porous sintering alloy lubricating layer on the single face of described steel plate.
Steel plate in above-mentioned or steel bushing preferentially adopt structural carbon steel.
The composition of porous sintering alloy lubricating layer is preferentially selected for use in above-mentioned: the alloy that is mixed by the cemented carbide of the Cu of the Fe of the P of the Ni of the Sn of 8-15% proportion, 20-30% proportion, 4-8% proportion, 15-25% proportion, 45-55% proportion and 1-5% proportion adds solid lubricant and forms the preferred flake graphite of wherein said solid lubricant.
The multiple layer of the high-mechanic high abrasion that the utility model obtains sintering is from moistening shaft type bearing and board-like bearing, it adopts steel plate or steel bushing as matrix, sintering, diffusion, joint porous sintering alloy lubricating layer on matrix, porous sintering alloy lubricating layer and base steel can engage firmly, make the utility model can carry higher heavy burden, no matter be the single face porous sintering alloy lubricating layer of board-like bearing or the porous sintering alloy lubricating layer of the bore area of shaft type bearing simultaneously, its rub resistance is strong, and relative friction coefficient is little.
