Background technology
Bearing is that part that is fixed and reducing load coefficient of friction is played in mechanical transmission course.It may also be said that when other
When parts produce relative motion each other on axle, for reducing coefficient of friction and the holding shaft center in power transmission process
Fixed parts.Bearing is a kind of very important parts in contemporary plant equipment.Its major function is support machinery rotation
Swivel, to reduce mechanical load coefficient of friction of the equipment in transmission process.By the difference of motor element frictional property, bearing
Rolling bearing and the class of sliding bearing two can be divided into.
The mechanical property of polyethylene is general, and tensile strength is relatively low, and creep resistance is bad, and impact resistance is good.Impact strength
LDPE>LLDPE>HDPE, other mechanical properties LDPE<LLDPE<HDPE.Mainly by density, crystallinity and relative molecular mass
Influence, with the raising of this several indexs, the increase of its mechanical property.Environmental stress crack resistance is bad, but when average molecular matter
During amount increase, make moderate progress.Paracentesis resistance is good, and wherein LLDPE is best.Using forming methods such as injection, blowing, extrusion molding, rotational moulding,
Production film article, commodity and industrial all size hollow container, tubing, the calendering band and ligation band being packed for, rope
Cable, fishnet and braiding fiber, electric wire etc..Although polyethylene can be molded into bearing parts, in high-mechanic occasion
The intensity of middle polyethylene bearing and anti-wear energy performance are not enough, and service condition is greatly restricted.
The content of the invention
The present invention for the present invention in order to solve in above-mentioned technology in high-mechanic occasion the intensity of polyethylene bearing and
It is anti-wear can performance it is not enough, service condition is greatly restricted etc., and not enough there is provided a kind of poly- second with high-mechanic performance
Alkene bearing, under conditions of extra manufacturing procedure and processing cost is not increased, but polyethylene bearing obtains higher resistance to
Mill property and high-mechanic performance, can meet the use of high request occasion.
The technical scheme is that：A kind of polyethylene bearing with high-mechanic performance, it is characterised in that by weighing as follows
The raw material of amount part, which is constituted, is：80 portions of ultra-high molecular weight polyethylenes, 20~40 parts of nitrile rubbers, 10~30 parts of self-lubricating agent, 0.1~
1 part of zinc oxide, 0.1~1 part of stearic acid, 0.1~2 part of crosslinking agent, 0.2~1.6 part of antioxidant, 20 parts of EVA modified resins, 0.4
~1.0 parts of di-sec-octyl phthalates, 1.5~3 parts of zinc oxide, 2~3.5 parts of foaming agents, 0.3~1 part of lead stearate, 12~
16 parts of carbon fibers, 5~10 parts of Nano graphite powders.
The foaming agent is AC foaming agents.
The di-sec-octyl phthalate is plasticizer.
The nitrile rubber is common nitrile rubber, hydrogenated nitrile-butadiene rubber or XNBR.
The self-lubricating agent is the one or two in graphite, molybdenum disulfide.
Beneficial effects of the present invention are：A kind of polyethylene bearing with high-mechanic performance proposed by the present invention, component is new
Grain husk, the present invention is while ultra-high molecular weight polyethylene self lubricity, the advantage of anti-wear performance is kept, by introducing self-lubricating agent
Further improve its anti-wear performance；By introducing rubber components, material is also improved while its water lubrication frictional behaviour is improved
The pliability of material, impact resistance is damping；And from PVvalue testing experimental result, super high molecular weight of the invention
The water lubrication coefficient of friction of composite polyethylene material is much smaller compared with ultra-high molecular weight polyethylene, is suitable as water lubrication shaft
Hold materials'use.
