The corrugated thrust surface bearing is characterized in that the thrust surface of the bearing takes the shape of a corrugation; the corrugated thrust surface includes alternated arranged wave crests and troughs; the wave crests are plane and in the same plane. The utility model provides a corrugated thrust surface bearing with small friction resistance, low noise and long service life, which improves the work environment, and reduces the energy consumption.
Description
Technical field
The utility model relates to a kind of bearing shell, belongs to technical field of mechanical structures.
Technical background
The axial pressure anti-attrition structure that various internal-combustion engine, compressor, mechanical transmission bore, both can be connected as a single entity with bearing itself, also can make with the equipped thrust plate of bearing be a kind of simple and easy assembly structure the Chinese patent of CN99254822.5 discloses as the patent No..Because the huge load that large power shaft is not only bearing radially carries, axially also there is bigger extruding force in rotating process.The classification of sliding bearing is a lot, and the plain tile that bears radial load is wherein arranged, and bears the thrust plate of thrust load, and the sliding bearing that bears radial and axial load simultaneously is called flanger bearing liner or thrust bearing shell.The patent No. is that the Chinese patent of CN200420017169.X discloses a kind of thrust plate that solves ablation of automobile engine crankshaft thrust plate antifriction alloy layer and fatigue flake problem, a kind of automobile engine crankshaft thrust plate is proposed, it is characterized in that: described thrust plate does not have the thrust plate backing, is single alloy-layer.This thrust plate changes the individual layer antifriction alloy into by the double-level-metal steel band, has not only improved the heat dissipation potential of thrust plate but also solved the fatigue flake problem of thin layer alloy anti-attrition layer, has avoided the generation that the impact fatigue of thin layer antifriction alloy is peeled off and ablated in the bimetallic material.But the life-span of this structure is shorter, and power consumption is high, and the noise of generation is bigger.The thrust working surface of monometallic heavy wall thrust (flange) bearing shell all is that plane adds two oil storage tanks, and this traditional break-in back that exists is still undesirable and be subjected to oil not good, and comparative lifetime is short.
Summary of the invention
The purpose that the utility model is led is to provide that a kind of surface friction drag is little, noise is low, the life-span is long, improves the ripple thrust surface bearing shell of working environment, has solved the problems referred to above that prior art exists.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs:
A kind of ripple thrust surface bearing shell, the thrust surface that it is characterized in that bearing shell is a corrugated, and described corrugated thrust surface comprises alternately arrange crest and trough, and described crest is plane and at grade.The thrust working surface of prior art generally is the plane, because the form and position tolerance after the amount of deflection of bent axle and the assembling, it is a very little face that the thrust working surface contacts with the bent axle plane in early days, need after long time break-in and the break-in also undesirable, the discontinuity of thrust plate, the life-span is low and cause early failue easily.The utility model adopts undulatory working surface, the crest of undulatory thrust surface and trough replace the part on relative bent axle plane, oil-containing is abundanter at the trough place, the crest face is as surface of contact, trough contains also than horn of plenty the contacting point of crest face and bent axle just as covering with paint or varnish in the process of rotation.The utility model can be finished early stage break-in fast, the stressed dispersion of thrust plate after the break-in, the actual receiving area in surface is big, have better conformity and protect functional oil, thrust surface is in the process of work, because crest and trough make that with the bent axle plane structure oil-containing of working surface is very abundant repeatedly, working surface has obtained cooling timely simultaneously, the sufficient friction portion of two metal surfaces or all be converted into the interior friction of flowing between membrane molecule under the lubricating status again, greatly reduce surface friction drag, the wearing and tearing of two metal coverings have been reduced, wash surperficial pollutant and abrasive particle simultaneously, improved energy consumption efficiency, prolonged operating life, improved the anti-fatigue performance of thrust surface, promptly improved working environment and saved the energy.
As preferably, the crest face of described thrust surface and trough are excessively slick and sly.This smooth easier the flowing of lubricant oil of excessively causing in the trough, the lubrication effect that is caused is better.
As preferably, described trough is smooth curved surface.Lubricant oil was difficult when trough was sharp-pointed base angle is taken out of in motion, and trough is got clogged, finally cause the wearing and tearing of surface of contact, adopt smooth curved surface to make the joint of trough and all very fairing of trough, like this lubricant oil excessively very easy between crest and trough.
As preferably, the pairing central angle of described crest be the pairing central angle of trough 0.5-1.5 doubly.Such ratio makes that oil flowing between crest and trough is more smooth and easy.
The height difference of crest and trough is crucial to being in whether lubricant oil in the trough can be brought on the working surface when the motion.As preferably, described height difference is between 0.1 millimeter to 0.5 millimeter.
As preferably, described crest and trough are evenly arranged on the thrust surface.Use uniform crest and trough, preferably crest equates with the pairing central angle of trough, reaches the highest as the crest of working surface with as the efficient of the trough of oil storage face like this, and the cooling and the lubricating efficiency of oil obtain bigger raising simultaneously.
As preferably, described crest is the class fan-shaped plan.Because all crests are all on the same ring plane, trough cuts off the ring plane on some crests, and fan-shaped crest is beneficial to flowing of lubricant oil.
Therefore, the utlity model has surface friction drag, characteristics such as noise is low, the life-span is long, oil-containing is abundant, operating temperature reduction.
Description of drawings
Accompanying drawing 1 is a thrust surface axial arrangement schematic representation of the present utility model;
Accompanying drawing 2 is transverse views of thrust surface shown in Figure 1.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1: a kind of as shown in Figure 1, 2 ripple thrust surface bearing shell, its corrugated thrust surface is relative with the hockey stick axle, described corrugated thrust surface is a ring, even interlaced arrangement has 8 crests 1 and 8 troughs 2 on the ring, crest 1 is a fan-shaped plan, all crests at grade, the height difference of crest plane and trough is 0.1 millimeter, crest institute is 18 degree to central angle, and trough institute is 18 degree to central angle.During work, be rich in lubricant oil in the trough, lubricant oil flows between crest and trough fast, has played the effect of cooling and removal of impurities in lubricated.The utility model has improved 1 times than the life-span of common commercially available thrust bearing shell, and noise is low, and energy consumption is little, has the good commercial prospect.
Embodiment 2: the height difference of crest plane and trough is 0.5 millimeter as different from Example 1, and crest institute is 18 degree to central angle, and trough institute is 12 degree to central angle.
Embodiment 3: the height difference of crest plane and trough is 3 millimeters as different from Example 1, and crest institute is 18 degree to central angle, and trough institute is 36 degree to central angle.
