Abstract
The utility model discloses the end face sliding bearings of double rubbing surfaces.It is the round-meshed annular plane sliding bearing of center system, it is characterized in that being steel plate among the plane sliding bearing, being sintered in the tow sides of steel plate has copper alloy layer, on the surface of two copper alloy layers, sintering has polytetrafluoroethylene ethylene layer, there is recessed arcwall face oil groove in the surface rolling of polytetrafluoroethylene ethylene layer, at least two, the arcwall face oil groove, and these arcwall face oil grooves and the center of circular hole of annular plane sliding bearing radially distribute.Since made oil groove is recessed arcwall face, different from common rectangle oil groove, using arcwall face oil groove double rubbing surfaces end face sliding bearing regardless of with friction shaft end be it is opposite rotate clockwise or rotate all be formed counterclockwise facilitate lubricating oil to import the secondary wedge lead-in angle of friction, lubricating oil is enabled to can smoothly enter into friction pair and form oil film, the secondary lubricating condition of friction and heat dissipation performance are improved, the abrasion of parts is reduced.
Description
Technical field
It further comprise the end face sliding bearing of double rubbing surfaces the utility model relates to sliding bearing.
Background technique
It is at present composite material there are many new material for making sliding bearing, which is at one of steel plate
Surface sintered copper powder, then it is sintered one layer of macromolecule antifriction material, then surface treated on the surface of copper powder layer, composite wood is made
Material, the material of oil-free sliding bearing is made of it, the sliding bearing made of this material can be in low speed and short time
It is not added or adds lubricating oil less, but there is still a need for lubricating oil when running at high speed.The shaft sleeve made of composite material is slided
Bearing no matter can form oil film when running at high speed and obtain satisfied effect in bath lubrication, drip lubrication and lubrication of splashing
Fruit, this is mainly that there are gaps between axis, set class, so that forming the lead-in angle of wedge between axis, set, lubricating oil is through lead-in angle energy
It can smoothly enter into friction pair and form oil film, therefore axis, the secondary oil film easy to form of friction for covering class, lubricating status are preferable.But for
It is as shown in Figure 1 and Figure 2, this although on the sliding bearing of end face in use, be formed with oil guide groove on the sliding bearing of end face
Oil guide groove is usually (the rectangle oil guide groove) of straight wall, when end-surface friction pair operates under higher linear velocity environment, as it is desirable that
The lubricating oil of engaging friction pair does not have the lead-in angle of wedge, and lubricating oil just can not be successfully engaging friction pair and form oil film, causes
Fever and the premature abrasion of parts and fail.The ball plain thrust bearing that many occasions can only use size big, at high cost.Especially
It is it is two-sided require be rubbing surface and higher linear velocity environment under, with common composite material and conventional rectangle Oil Guide
Slot production end face sliding bearing is just unable to satisfy requirement.
Utility model content
It is small that the mesh of the utility model is to provide a kind of friction factor, long service life, and structure size is small, low manufacture cost,
The end face sliding bearing of double rubbing surfaces of alternative ball plain thrust bearing.
In order to reach above-mentioned requirements, the end face sliding bearing of double rubbing surfaces of the utility model, it is that center is formed with circular hole
Annular plane sliding bearing, it is equal in the tow sides of steel plate it is characterized in that be steel plate among the plane sliding bearing
Sintering has copper alloy layer, and on the surface of two copper alloy layers, sintering has polytetrafluoroethylene ethylene layer, in the surface rolling of polytetrafluoroethylene ethylene layer
There is a recessed arcwall face oil groove, at least two, the arcwall face oil groove, and these arcwall face oil grooves and annular plane
The center of circular hole of sliding bearing radially distributes.
The front shape of the arcwall face oil groove is fan-shaped surface.
The copper alloy layer with a thickness of 0.2-0.3 millimeters.
According to the end face sliding bearing of double rubbing surfaces of above scheme design, since made oil groove is recessed arc
Face, different from common rectangle oil groove, using arcwall face oil groove double rubbing surfaces end face sliding bearing regardless of with friction shaft end
Be it is opposite rotate clockwise or rotate all be formed counterclockwise facilitate lubricating oil to import the secondary wedge lead-in angle of friction so that
Lubricating oil can smoothly enter into friction pair and form oil film, improve the secondary lubricating condition of friction and heat dissipation performance, reduce parts
Abrasion.In addition, the end face sliding bearing is double rubbing surfaces, it can the opposite sliding for lowering end face sliding bearing and two friction parts
Speed improves the service life of end face sliding bearing.In the forming of arcwall face oil groove, can be used hard cylinder or
Conical pressure head, is suppressed, simple process, high production efficiency.It has axial ruler than common Plane Ball thrust bearing
The advantages of very little small, structure is simple, low manufacture cost, high production efficiency.
Detailed description of the invention
Fig. 1 is the main view of the end face sliding bearing of existing single rubbing surface；
Fig. 2 is A-A profile of Fig. 1；
Fig. 3 is the main view of the end face sliding bearing of double rubbing surfaces；
Fig. 4 is B-B profile of Fig. 3；
Fig. 5 is partial enlarged view of the end face sliding bearing of double rubbing surfaces in use state.
In figure: the end face sliding bearing of 1. pairs of rubbing surfaces；2. circular hole；3. steel plate；4. copper alloy layer；5. polytetrafluoro
Pvdf layer；6. arcwall face oil groove；7. rub shaft end；8. lubricating oil；9. oil film.
Specific embodiment
The utility model will be further described in the following with reference to the drawings and specific embodiments.
Fig. 3, Fig. 4 are the structural schematic diagrams of the end face sliding bearing of double rubbing surfaces.The end face of double rubbing surfaces as seen from the figure
Sliding bearing 1 is the annular plane sliding bearing that center is formed with circular hole 2, the section structure of the plane sliding bearing, in
Between be steel plate 3, be sintered in the tow sides of steel plate 3 has copper alloy layer 4, and the thickness S of copper alloy layer 4 is 0.2-0.3 millimeters.?
The surface sintering of two copper alloy layers 4 has polytetrafluoroethylene ethylene layer 5, has 4 recessed arcs in the surface rolling of polytetrafluoroethylene ethylene layer 5
6,4 arcwall face oil grooves 6 of face oil groove and 2 center of circular hole of annular plane sliding bearing radially distribute.And single arc
The front shape of face oil groove 6 is that fan-shaped surface is as shown in Figure 3.
In use, regardless of friction shaft end 7 rotates clockwise or rotates counterclockwise, the end face sliding of double rubbing surfaces
The tangent line of arcwall face oil groove 6 on bearing 1 and friction shaft end 7, which can all be formed, facilitates lubricating oil 8 to import the secondary wedge importing of friction
Angle K as shown in figure 5, to enable lubricating oil 8 to can smoothly enter into friction secondary and form oil film 9, improve the secondary lubricating condition of friction and
Heat dissipation performance reduces the abrasion of parts.
