1. The sprocket chain has poor transmission stability, and there will be impact and noise during operation:

2. Sprocket chains are not suitable for high-speed occasions or occasions where the direction of rotation changes frequently.

3. Precautions for assembling sprocket chain:

3.1 The fit between the sprocket and the shaft must meet the design requirements.

3.2 The geometric center planes of the teeth of the driving sprocket and the driven sprocket should coincide, and the offset should not exceed the design requirements. If not specified in the design, it should generally be less than or equal to 0.2% of the center distance between the two wheels.

3.3 When the chain engages with the sprocket, the working edge must be tightened and the engagement must be smooth.

3.4 The sag of the non-working side of the chain should meet the design requirements. If not specified in the design, it should be adjusted to 1% to 2% of the center distance between the two sprockets.

4. Precautions for maintenance of sprocket:

4.1 The tightness of the sprocket should be appropriate: the tightness of the sprocket is: when lifting or pressing down from the middle of the sprocket, the center distance between the two sprockets is about 2%-3%;

4.2 The sprocket should be installed on the shaft without swinging or skewing;

4.3 If the sprocket/chain transmission is severely worn, it is advisable to replace the sprocket and chain at the same time to ensure good meshing.

4.4 If the new sprocket is too long or stretches after use and is difficult to adjust, the chain links may be removed depending on the situation, but the number must be an even number.

4.5 The sprocket/chain should be lubricated in time to improve working conditions and reduce wear;

4.6 New and old sprockets cannot be used together. If necessary, they should be replaced in matching pairs. Otherwise, impact will easily occur during transmission. Mixing new and old sprockets will increase wear.

4.7 When the machine is idle for a long time, the sprockets that are at risk of rusting should be removed, cleaned with kerosene or diesel, and then coated with engine oil or butter and stored in a dry place.
