1, sprocket installed on the shaft should not skew and swing. In the same transmission component of the two sprocket end face should be located in the same plane, sprocket center distance in 0, 5 meters below, allowable deviation of 1 mm; Sprocket center distance in 0, 5 meters above, allowable deviation of 2 mm. But do not allow friction sprocket tooth side phenomenon, if the two wheels offset too easy to produce chain and accelerated wear. The offset must be checked and adjusted when replacing the sprocket.
2, the tightness of the chain should be appropriate, too tight to increase power consumption, bearing easy to wear; Too loose chain easily jump and unchain. The tightness of the chain is: lifted or pressed down from the middle of the chain, and the center distance between the two sprockets is about 2-3cm.
3. The new chain is too long or elongated after use, which is difficult to adjust. It can be removed according to the situation, but it must be even. The link shall pass through the back of the chain, the lock piece is inserted on the outside, and the opening of the lock piece shall face the opposite direction of rotation.
4, sprocket wear serious, should be replaced at the same time with a new sprocket and new chain, to ensure good engagement. You can't just replace a new chain or a new sprocket separately. Otherwise, it will cause poor meshing and accelerate the wear of the new chain or sprocket. Sprocket tooth surface wear to a certain degree should be timely turned over to use (refers to adjustable surface used sprocket). To extend the use time.
5, the old chain can not be mixed with part of the new chain, otherwise it is easy to have impact in the transmission, pull the chain.
6. The chain should be filled with lubricating oil in time during the work. Lubricating oil must enter the matching gap between the roller and the inner sleeve to improve working conditions and reduce wear.
7. When the machine is stored for a long time, the chain should be removed and cleaned with kerosene or diesel oil, and then coated with oil or butter and stored in a dry place to prevent corrosion
