Abstract
An oil-storage type self-lubricating chain includes a plurality of chain links. Each chain link comprises an inner chain plate, an outer chain plate, pin shafts, a shaft sleeve and a roller; and the pin shafts include a long pin shaft and a short pin shaft. The utility model is characterized in that an oil storage cavity with one opening end is arranged axially at one end of each of the long pin shaft and the short pin shaft, and an oil valve is further included and arranged in the opening of each oil storage cavity; and oil storage tanks are arranged on the radial outer surfaces of the long and the short pin shafts, and are communicated with the oil storage cavities through radial oil channels. Due to the adoption of the structure, the oil storage cavities are communicated with the clearance between the long and the short pin shafts, thereby ensuring the lubrication between the long and the short pin shafts and the shaft sleeve; and the oil valve is arranged, so that the oil storage cavities can be replenished with lubricating oil in time conveniently, and the utility model can efficiently prevent the lubricating oil from being washed away by rain and avoid rustiness of a roller chain, dry grinding between the roller and a chain wheel, and influences on the mechanical transmission performance and the service life of the roller chain.
Description
Technical field
The present invention relates to a kind of roller type chain, especially a kind of selflubricating formula chain.
Background technique
Present prior art, roller chain generally is used for mechanical power transmission system, and traditional roller chain often needs roller chain is refueled maintenance, even oil-free chain in the past, along with the lengthening of service time, lubrication effect is not obvious, particularly under outdoor situation more very.In using process for many years, find to have following deficiency aspect main.
1, once the back lubricated time of oiling is short.Conventional chains is behind fatten, because grease is exposed outside, grease is easy to run off, in the time of particularly outdoor, grease is easy to just be fallen by rain wash, causes roller chain to get rusty, roller and sprocket wheel are dry grinded, and influence the life-span of mechanical transmission performance and roller chain.
2. common chain wants frequent chain is refueled to safeguard, has increased man hour of labour and cost of material virtually, befouling environment, and also effect is also undesirable.
3. dustproof and waterproof weak effect.The conventional chains sealing effect is not good, and rainwater enters lubricated face easily, causes that chain gets rusty to cause mechanical wear and produce noise.
Summary of the invention
The objective of the invention is: a kind of oil storage type oil-free chain is provided, and it not only has oil storage, characteristics repeatedly, but also can guarantee axle sleeve and bearing pin sufficient lubrication.
The present invention is achieved in that a kind of oil storage type oil-free chain, comprise some chain links, described chain link is made of inner plate, outer plate, bearing pin, axle sleeve and roller, described bearing pin is divided into have strong market potential axle and short pin shaft, its special way is: an end of described long and short bearing pin has shoe cream room vertically, an end opening, also comprise a fuel tap, fuel tap is arranged in the opening of shoe cream room; On the radially-outer surface of described long and short bearing pin oil storage tank is arranged, oil storage tank is communicated with shoe cream room by radially oily passage.
Described a kind of oil storage type oil-free chain, its special way is: on the internal surface of described axle sleeve spiral chute is arranged, spiral chute cooperates with oil storage tank.
Described a kind of oil storage type oil-free chain, its special way is: described fuel tap is made of valve body, ball and pressure spring, and an axial end of valve body has filler opening, the other end that oil outlet is arranged, and ball cooperates with filler opening; Pressure spring one end cooperates with ball, and the other end cooperates with interior ring platform on the oil outlet.
Described a kind of oil storage type oil-free chain, its special way is: also comprise a seal ring, described seal ring is enclosed within on the axle sleeve between inside and outside carrier bar.
Described a kind of oil storage type oil-free chain, its special way is: circular cone ring and female cone platform shape ring in the annulus, of the radial edges of described seal ring flanging in the center of circle is disposed with a band;
Also comprise a friction washer, friction washer is arranged on the axle sleeve, and friction washer is fixed on the outer plate, between seal washer and outer plate; The flanging of annulus and the sagittal plane of friction washer closely cooperate, and middle truncated cone ring and female cone platform shape ring closely cooperate with the axial vane surface of friction washer.
A kind of oil storage type oil-free chain of the present invention, an end of described long and short bearing pin have shoe cream room vertically, an end opening, also comprise a fuel tap, and fuel tap is arranged in the opening of shoe cream room; On the radially-outer surface of described long and short bearing pin oil storage tank is arranged, oil storage tank is communicated with shoe cream room by radially oily passage.Owing to adopt such structure, shoe cream room communicates with gap between axle sleeve and the long and short bearing pin, can guarantee lubricating of long and short bearing pin and axle sleeve; The setting of fuel tap can make things convenient for make-up oil in shoe cream room in time, can prevent effectively that lubricant oil from being fallen by rain wash, causes roller chain to get rusty, and roller and sprocket wheel are dry grinded, and influences the life-span of mechanical transmission performance and roller chain.
