Description
The present invention relates to structural type and the manufacture method thereof of radial sliding bearing with axial sleeve of bushing.Be suitable for adopting and make the bearing axial sleeve of bushing, be particularly suitable for adopting laminated composite material sheet material to make heavy wall bearing axial sleeve of bushing than precious materials sheet material.
For the axial sleeve of bushing that the radial sliding bearing on the machine is used, technique known has: with the bearing bush axle sleeve of copper base alloy manufacturing; Adopt the steel-copper compound structure bearing of centrifugal casting or the bearing or the axial sleeve of bushing of axial sleeve of bushing and the manufacturing of employing steel back composite sheet material.The latter mainly divides steel backing multi-layer metal composite material class and steel backing polymer composites class, and they all are the layered laminate composite material.Because their more preceding two kinds of materials have a series of superiority, it is widely used in mechanical engineering.Wherein the steel backing multi-layer metal composite material is widely used at ic engine industry.And Britain invents at first and " DU " (steel backing ptfe composite) of once patenting.The axial sleeve of bushing of these two kinds of materials of " DX " (steel backing polyformaldehyde composite material) also is widely used in the mechanical engineering.In addition, also adopt the laminated composite material sheet material (band) of some other pattern to make axial sleeve of bushing in the technique known.Japan Patent JP58-77916 for example, it is that the one side that is used in sheet metal is bonded with and is arranged side by side with the laminated composite material sheet material of fluoridizing resin at regular intervals and will makes a kind of plain bearing bush along fluoridizing mode of structure and the manufacture method that the resin bar vertically directly bends to cylinder type after this sheet material processing, the blanking to disclose a kind of " plain bearing arrangement and manufacture method ".Now, the industrial stacked composite board of polytype anti-friction wear-resistant of having produced.And the multiple method that laminated composite material plate (band) section bar is rolled into radial sliding bearing arranged.B. P. GB2101233A discloses a kind of method that rolls radial sliding bearing and axial sleeve of bushing and has designed the process step that processes V-groove before the final blanking of laminated composite material plate (band) section bar that is used to make rolling bearing at the cutting of material position in advance especially in the technique known, quality problems such as delamination occur to avoid the cutting of material position.Better through its end material shape quality of radial sliding bearing that such blanking directly rolls.Although but the laminated composite material advantage is very big, good but the advantage of expensive bearing metal of cheap steel and friction and wear behavior although steel back composite has fully utilized good mechanical property, have the strong point of bringing into play different materials effectively, improve the advantage of the service behaviour of sliding bearing.But for many years owing to be confined to directly sheet bending be become the manufacture method of cylinder type, therefore be subjected to the restriction of laminated composite material anisotropy characteristics and the restriction of existing manufacturing technology, the axial sleeve of bushing goods that use laminated composite material sheet material to adopt traditional structural type and stamping technology directly to produce often are difficult to control its Forming Quality.In addition, the relatively poor sheet metal bending part of its formed precision also is unsuitable for as blank and is processed as the bearing shell product through big surplus machine cut.Because so still can take place such as product bearing material layer thickness inequality, the quality problems of local serious attenuate and so on.Just because said structure, production problem, produce wall thickness below 4 millimeters for therefore at present industrial general, the bearing material layer is also thin to adopt traditional stamping process manufacturing, the thin-walled steel backing composite shaft watt axle sleeve of quality more easy to control.Because the bearing shell wall is thin, the bearing material layer is also thin, should not be used in heavy duty, and the service condition harshness requires on all thicker machine of bearing shell wall bearing material layer.Steel back composite sheet material can not made the present situation of the good thick walled half bearing axle sleeve of practicability in view of still having ready-made structure and technological method, influence the Application and Development of this material in heavy machinery thick walled half bearing axle sleeve scope commonly used.
Purpose of the present invention is exactly in order to overcome above-mentioned defective, design a kind of radial sliding bearing with axial sleeve of bushing new structure and manufacture method thereof, realize with heavy wall plate (band) section bar (as follows) particularly heavy wall composite panel (band) section bar make the purpose of radial sliding bearing usefulness axial sleeve of bushing few cutting, that Forming Quality is good.
The object of the present invention is achieved like this: be furnished with on the composite board that the manufacturing bearing of using by design is used and a series ofly running through plate (band) section bar just or the groove structure that generally is straight shape or the subdivision structure of the surperficial length and width profile of reverse side (it is the front with the one side that the friction reducing abrasion resistant material layer is arranged), these groove structures or subdivision structure make sheet material produce a series of thin-walleds structure, cause the intensity of sheet material to weaken at the thin-wall configuration place and are easy to bending forming.Is the polyhedron blank of regular polygon with this sheet material bending for the cross section perpendicular to center line, groove structure or subdivision (combination) structure of sealing, connecting on it with conventional welding, gluing, mounting technology makes it typing again, just can produce the formal blank of the high polyhedron of formed precision, thereby available few bite is processed into axial sleeve of bushing.Have on the axial sleeve of bushing of making a series of self-existent, circumferentially along its axial direction or solid of rotation revolution bus that distribute with above-mentioned sheet material.Corresponding groove structure of the relevant structure of blank or combinating face structure, or connect the sealing of material or mounting technology with welding, viscose glue and stop up ditch, groove structure or the combinating face structure that connects.Be generally used for welding, viscose glue connects.The groove structure on the assembling sealing obstruction axial sleeve of bushing or the material of combinating face structure are common mechanical engineering material.When the relevant structure of axial sleeve of bushing slip working surface adopted the material that contains solid lubricant, self lubricating material sealing, filling, axial sleeve of bushing promptly had self-lubricating property and can form the selflubricating axial sleeve of bushing.
The axial sleeve of bushing new structure can be divided into four fundamental types by the position distribution of groove combination face structure and the design that runs through the position: 1, have respectively on its solid of rotation internal structure external structure a series of circumferentially, move towards the groove structure or the combinating face structure that distribute along solid of rotation revolution generatrix direction, or with welding, viscose glue connect material, mounting technology seals ditch, groove, the combinating face class formation of connection.2, its solid of rotation away from have on the axial direction external structure a series of circumferentially, move towards the groove structure or the combinating face structure that distribute along the revolution bus, or with welding, viscose glue connect material, mounting technology seals ditch, groove, the combinating face class formation of connection.Inner turning surface adopts sheet material continuous material layer to form.3, its solid of rotation is near having a series of groove structure or combinating face structures that circumferentially, distribute along the revolution bus on the internal structure of axial direction, or connects ditch, groove, the combinating face class formation of material, mounting technology sealing connection with welding, viscose glue.Outside turning surface adopts sheet material continuous material layer to form.4, have circumferentially a series ofly on the solid of rotation, the combinating face structure that runs through inner and outer surface that distributes along the revolution bus forms the sector unit composite structure.
When design one is made, can select the structure such as groove structure, combinating face structure on said structure type, each structure type should run through an one end face as required to another end face, being beneficial to adopt the sheet material bending forming with groove structure or subdivision structure is that the cross section is a polygonal, and there is the polyhedron blank of a series of flangings the side.The axial sleeve of bushing blank is designed to the polyhedron pattern, and its cross section perpendicular to axis generally is designed to normally regular polygon pattern of polygonal.A series of groove structures corresponding with the side flanging or combinating face structure are arranged on the blank of moulding, or tie the structure of the ditch of material, mounting technology sealing connection, groove, combination Noodles with welding viscose glue.Adopt the geometrical shape cylindrical or the inner circular part position in its cross section of this blank to produce the design that can estimate in advance one manufacturing form variations △ ' and △ ", the formed precision of this deviation effects blank and the materials consumption of course of working.When adopting laminated composite material sheet material to make blank, also to influence the accuracy of manufacturing and the materials consumption thereof of its useful materials layer." must design the number of blank side flanging or the number of cross section regular polygon more for reducing this deviation △ ' and △.According to the relation of respective graphical generally with axial sleeve of bushing cross section cylindrical or interior circle be as the criterion design circumscribed or in meet design one manufacture deviation △ ' and the △ that regular polygon is a design configuration control blank ".Be the number on regular polygon limit, blank cross section that is the number of the corresponding flanging in blank side according to the limit number of the regular polygon of above-mentioned requirements design.That is on the blank, corresponding groove structure or combinating face structure on the axial sleeve of bushing, or connect the groove that the sealing of material mounting technology connects, the number of combinating face class formation, regulation calculating in the following relationship in the present invention with welding, viscose glue:
