Abstract
The composite bearing is composed of internal and external layers. Said internal layer is made up of copper powder (40-50%), teflon (40-50%) and gypsum (10-20%) by solidifying at 80-380 deg.C/2th. Said external layer is made up of epoxy resin (30-40%), medlin (20-30%) and non-alkaline glass fibre (40-50%) by solidifying at 80-140 deg.C/1th. Solidified semi-finished product is mechanically processed. It features good chemical stability, high antiwear and anticorrosion nature, low friction resistance and high strength.
Description
The present invention relates to the substitute products of metallic sheath field of bearings.
The applicable surface of metallic sheath bearing is very wide, all selects the metallic sheath bearing for use as workplaces such as rotating, oscillating, reciprocating and sliding.Copper sheathing bearing in the metallic sheath bearing is exactly use always a kind of, also have bearing productss such as nylon jacket and teflon now, because the copper sheathing bearing is crisp, frangible, though antifriction but friction factor height, and nylon jacket and teflon bearing easily are out of shape with the temperature rising, thereby the development of new material bearing is just indispensable.
The object of the invention provides a kind of composite bearing and preparation process thereof of excellent performance, thus alternative metals cover bearing.
Composite bearing of the present invention is internal layer and outer two-layer composition, and represent with weight percentage: internal layer is made up of 40～50% copper powders, 40～50% teflon and 10～20% graphite; The outer non-twist glass fibre of alkali-free by 30～40% epoxy resin, 20～30% polyimide and 40～50% is formed.
The manufacturing process of composite bearing of the present invention is: the inner layer material of hand being stuck with paste preparation evenly is applied on the mould, in baking box, progressively heat under the normal pressure, be warming up to 380 ℃ gradually from 80 ℃ with 2 hour time, twine the glass fibre that soaked with epoxy resin that stirs evenly and polyimide behind the outlet immediately, adopt the spiral canoe, its winding angle is 45～55 °, up to workpiece preliminary dimension thickness, heating from 80 ℃ → 140 ℃ with 1 hour solidifies it, and lathe is processed into finished product on the semi-finished product after the curing.
Mould in the above-mentioned processing technology requires straight qualified, and degree of finish is good, and being coated with must be with hairbrush brush one deck releasing agent (as polyvinyl alcohol) on mould before the inner layer material.
Composite bearing product of the present invention, as follows through its relevant data of test on probation:
Bearing capacity (low speed steady load) 56MPa
Dry friction coefficient 0.06～0.08
Oil lubrication coefficient 0.04～0.07
50～180 ℃ of serviceability temperatures (serviceability temperature during test)
Limit PV value (dry friction) 300
Oil lubrication friction number of times＞30000 time
The inner layer material of composite bearing of the present invention also can be added epoxy resin (as 85# epoxy resin) and curing agent, and then wherein the amount of copper powder and teflon can correspondingly reduce, and cost also will reduce, but the high occasion of usage requirement should not add epoxy resin.
Composite bearing of the present invention is applicable to the oil-free lubrication occasion, have that satisfied chemical stability, surface friction drag are little, antifriction damage, long service life, mechanical strength height, corrosion resistance and good, can be applicable in the various aggressive mediums, applicable to operating modes such as rotating, oscillating, reciprocating and sliding, the occasion of every use metallic sheath bearing, an all available composite bearing substitutes it.
Embodiment:
