Chain sprocket applications: widely used in chemical, textile machinery , food processing , instrumentation , oil and other industries , such as mechanical transmission .
Chain Model: contains non -standard sprockets ( customized according to customer drawings ), standard sprocket ( American standard and metric ) .
Sprocket commonly used materials : C45
Sprocket teeth should ensure that the material has sufficient strength and wear resistance , the surface of the sprocket teeth are generally heat treated , so as to achieve a certain hardness .
Sprocket common processing methods : quenching, black surface treatment
1 , the tightness of the chain sprocket should be appropriate, too tight will increase power consumption , bearing easy to wear ; too loose off the chain and sprocket easily beating . Tightness of the chain is: lift or pressure from the middle of the chain , the two sprocket center distance of about 2 % -3 %.
2 , sprocket mounted on the shaft should be no wobble and skew . In both end surfaces of the same chain drive assembly to be located in the same plane, the sprocket center distance 0.5 m or less, the deviation 1 mm ; center distance when a chain of more than 0.5 m , the deviation can be 2 mm . But not the phenomenon of friction sprocket side , if two offset too large chains and prone to accelerated wear off . When replacing the sprocket must be careful to check and adjust the offset.
3 , sprocket wear serious , it should also replace the new chain sprockets and new , to ensure good engagement . Not just a single new replacement sprocket or sprockets . Otherwise it will cause bad engagement , accelerate new sprocket or new sprocket wear. Sprocket tooth wear to a certain extent should be promptly turned over to use ( refer to the surface using an adjustable chain ) , to extend the use of time .
4, new or used chain sprocket elongation after long and difficult adjustment , removed the link to see the situation , but it must be an even number. Back through the chain links should the locking plate is inserted on the outside, the opening of the lock piece to be rotated toward the opposite direction.
5 , sprockets at work should be promptly filling oil . Lubricants must enter the roller and the inner sleeve with the gap , to improve working conditions and reduce wear.
6 , the old part of the new chain sprocket can not be mixed with , or prone to shocks in the drive , and pull off the sprocket.
7 , when the machine is long-term storage , remove the chain sprocket should be cleaned with kerosene or diesel oil , then coated with oil or butter stored in a dry place.
