Abstract

The utility model relates to a chain, particularly a chain which can meet the requirements of high driving performance and is capable of rub resistance. The utility model discloses a self-lubricating chain, which comprises a pin shaft which is sheathed with a sleeve barrel, and the sleeve barrel is sheathed with a roller; both sides of the pin shaft are respectively connected with an inner chain plate and an outer chain plate; the position between the sleeve barrel and the pin shaft is sheathed with bearings which are made of plastics; a layer of bearings which are made of plastic are additionally arranged between the sleeve barrel and the pin shaft so as to achieve the self-lubricating purpose without adding any lubricating oil and meanwhile provide the self-lubricating chain which is characterized in that under the condition of a long working time, the chain is hard to generate heat and the friction surface is hardly burnt to be clamped due to gluing besides other characteristics of small vibration and low noise.

Description

Oil-free chain
Technical field
The utility model relates to a kind of chain, especially relates to a kind ofly being used for that transmission performance is had relatively high expectations and the chain of rub resistance.
Background technique
Advantages such as chain-driven and belt pulley velocity ratio have the stable advantage of transmission, and sprocket tooth is stressed less, and it is also lighter to wear and tear, and better buffering is arranged, and absorbing is strong, and the accommodation of centre distance is big are widely used in the various machinery.But chain-driven needs enough lubricating under normal conditions, guarantee the usability of chain, but also there is a large amount of application examples to show, chain greasisng is insufficient maybe can not to be lubricated, the reason that produces this situation is because the characteristics of chain structure own, or chain-driven is in the working condition decision of sealing, can't carry out sufficient lubrication from the external world, also may greasing can influence institute's product processed thereby can not lubricate.If any people design " frustoconic shape bearing pin die chain " (Chinese patent notice of authorization number: CN 2581754Y), it is by outer plate with existing, inner plate, the chain roller, the die of the bearing pin of the chain that axle sleeve and bearing pin constitute is made frustoconic shape, it has riveted joint firmly, advantages such as the twisting resistance of chain is strong, but the defective that has the conventional chains design, promptly need from external world's interpolation lubricant oil, can not self oiling, if and do not having under the lubricated situation about maybe can not lubricate, the technical problem that the life-span of chain will shorten greatly, if exist the operating time of chain long simultaneously, chain will generate heat, friction surface is burnt easily, can glue together stuckly, and also has the big technical problem such as noise that forms easily of vibration.
Summary of the invention
The utility model solves that prior art is existing can not self-lubricated technical problem, and providing can self-lubricated oil-free chain.
The utility model also solves the existing operating time reel chain of prior art and will generate heat, friction surface is burnt easily, gummed is stuck easily, and technical problems such as the big formation easily of vibration noise, provide at long situation lower chain of operating time and be not easy heating, friction surface is not easy burn, and it is stuck to be difficult for gummed, and vibrates the little oil-free chain of little noise.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: oil-free chain, comprise bearing pin, be with sleeve on bearing pin, roller sleeve is on sleeve, connect inner plate and outer plate respectively in the bearing pin both sides, between sleeve and bearing pin, be with the bearing that plastics are made.Between sleeve and bearing pin, increase the bearing that one deck plastics are made, can add lubricant oil, reach self-lubricated purpose.
As preferably, bearing is the hollow circular tubular structure.
As preferably, between sleeve and bearing pin, be with the bearing that fluoro-containing plastic is made.The bearing that fluoro-containing plastic is made has resistance to heat, decay resistance, and have not viscosity, rub resistance, ageing-resistant, need not add lubricant oil in addition during chain work, play self-lubricated purpose, the situation lower chain long in the operating time is not easy heating, and friction surface is not easy burn, it is stuck to be difficult for gummed, and it is little to vibrate little noise
As preferably, between sleeve and bearing pin, be with the bearing that teflon is made.The bearing that teflon is made has excellent high temperature performance and chemical stability, can bear alkali metal, fluorinated dielectric and the effect that is higher than all strong acid (comprising chloroazotic acid), strong oxidizer, reducing agent and various organic solvents outside 300 ℃ of sodium hydroxide except fusion; Well electrical insulating property, be not subjected to the influence of environment and frequency, volume resistance can reach 1018 ohmcms, relative permitivity is little, wears the voltage height; Non-adhesive, heat resistance, warm territory scope is wide, but 260 ℃ of serviceability temperature-190 ∽; Very little friction factor does not burn and good unique self lubricity-has; Excellent resistance to weathering, radiation-resistant property and lower permeability-long term exposure are in atmosphere, and surface and property retention are constant.
As preferably, between sleeve and bearing pin, be with the bearing that nylon is made.The bearing that nylon is made also has heat-resisting, decay resistance, and has not viscosity, and rub resistance is ageing-resistant, need not add lubricant oil in addition during chain work, plays self-lubricated purpose.
As preferably, between sleeve and bearing pin, be with the bearing that oil-containing nylon is made.The bearing that oil-containing nylon is made has very big accommodation, 200 ℃ of heat distortion temperatures, and working environment can arrive 180 ℃ of high temperature, and low temperature-40 ℃ its performance is constant; Have good self lubricity, reduce friction ractor, oil-free lubrication in the work reduces and pollutes, and is beneficial to environmental protection, prolongs the working life of parts; The modular ratio metal is little, and the vibration attenuation rate is bigger tens times than metal, has the function of shock-absorbing noise abatement; Anti-various soda acid salt corrosion, 50 years working life of normal temperature, anti-insulation, nontoxic, tasteless, pollution-free.
As preferably, described bearing and bearing pin have certain interval, are that rolling friction cooperates bearing and sleeve interference fit between the two.Bearing and bearing pin are rolling friction, do not have relative movement between bearing and the sleeve substantially.
