Details about the maintenance and definition of sprocket & ndash;
Sprocket machining a, sprocket & ndash;
Sprocket maintenance: 1, appropriate to the looseness of the chain pulley, too tight will increase power consumption, bearing wear and tear;
Too loose chain easy to beat and take off the chain.
Tightness of sprocket: filed or under pressure from the central part of the chain wheel, chain wheel center distance of about two 2% to 3%.
2, chain wheel mounted on a shaft should not swing and skew.
Two sprockets face in the same transmission components should be located on the same plane, the sprocket center distance in 0.
5 meters, can be deviation of 1 mm;
Sprocket center distance in 0.
More than 5 meters, can be deviation of 2 mm.
But you can't have friction sprocket profile phenomenon, if the two rounds of offset too prone to take off the chain and accelerated wear and tear.
When replacing sprocket must pay attention to check and adjust the offset.
3, after the sprocket wheel wear serious, should replace new sprocket and chain wheel at the same time, to ensure good mesh.
Can not only replace new sprocket or sprocket alone.
Otherwise it will cause bad meshing speed new sprocket or new sprocket wheel wear.
Sprocket tooth surface wear to a certain degree to flip timely after using (
Adjustable surface using sprocket)
To extend the use time.
4, new chain wheel is too long, or elongation after use, it is difficult to adjust, can see things down link, but must be even.
Through the link from the chain wheel on the back of the lock plate inserted in the outside, lock piece of opening should be toward the rotation in the opposite direction.
5, sprocket in the work should be timely filling lubricating oil.
Lubricating oil must be into the roller and the inner sleeve fit clearance, to improve working conditions, reduce wear and tear.
6, old cannot be used mixed with part of the new chain sprocket, otherwise easy to impact in the transmission, snap sprocket.
7, machine long stored, chain wheel should be removed with kerosene or diesel clean, then coated with oil or butter in a dry place.
Second, the sprocket processing & ndash;
Sprocket: the definition of chain wheel is with embedded tooth buckle sprocket wheels, to link and section or pitch accurate block on cable mesh [
: a solid or with the spokes of the gear, and (
Chain mesh to pass motion.
The sprocket tooth profile sprocket tooth profile must ensure that the chain energy saving mesh smooth entry and exit freely, minimize the impact of the meshing of link and contact stress, and is easy to be processed.
