Galvanized chain and iron chain precautions

Today, give us a brief introduction to the precautions for galvanized chain and iron chain, let's have a look:

1, sprocket installed on the shaft should not tilt and swing. The end faces of the two sprockets in the same safety chain and transmission component should be located in the same plane, and the sprocket base distance is less than 0.5 meters, allowing an error of 1 mm; When the sprocket base distance is more than 0.5 meters, the error of 2 mm is allowed. However, it is not allowed to have a conflict on the side of the sprocket teeth, if the two wheels are shifted too much, it will simply take off the chain and accelerate the wear. When replacing the sprocket, it is necessary to pay attention to check and adjust the deflection amount.
2, the tightness of the galvanized chain should be suitable, too tight increase decorative chain power consumption, bearing easy to wear; Too loose a chain can jump and break. The tightness of the chain is: lifted or pressed from the middle of the chain, the base distance of the two sprockets is about 2%-3%.
3, the new lifting chain is too long or extended after use, difficult to adjust, can be removed depending on the condition of the chain, but it is necessary to be even. The chain link should pass through the opposite side of the chain, the lock plate is inserted on the outside, and the opening of the lock plate should face the opposite direction of the rolling.
4, after the sprocket wear is severe, the new sprocket and the new chain should be replaced at the same time to ensure outstanding engagement. You can't just replace a new chain or a new sprocket. Otherwise, it will form poor meshing and accelerate the wear of the new chain or new sprocket. Sprocket tooth surface wear to a certain degree should be used in time to turn over (refers to the adjustable surface of the sprocket). To extend the operation time.
5, the old lifting chain can not be mixed with some new chains, otherwise it will simply impact in the transmission and break the chain.
6, galvanized chain in the work to remember to fill lubricating oil in time. The lubricating oil is necessary to enter the cooperation gap between the roller and the inner sleeve in order to improve the working conditions to reduce wear.
