1. When selecting the sprocket, the model must be selected correctly according to the specifications.

 2. Put the main and driven sprocket devices in place according to the correct method, and tighten the fasteners to reach the regular torque request.

 3. After installing the drive chain and adjusting the tightness, check whether the chain and the sprocket are smoothly matched, coplanar, and there is no interference with the chain cover.

 4. Check whether the position of the transmission sprocket (transmission output countershaft, hub, etc.) of the device is in good condition, otherwise the relevant parts must be overhauled or replaced.

Matters needing attention during the use of sprocket:

 1. The driven sprocket should have anti-loosening measures.

 2. Regularly clean and smooth the transmission chain and transmission sprocket to improve its service life.

 3. The sprocket and chain are changed at the same time. If only one of them is changed, the wear of both will be aggravated.。

 4. After the driven sprocket is loaded into the car, the rear wheel axle should be adjusted with the conditioner and the rear cradle (also called the rear wheel fork). This can prevent the rear wheel from deviating and prevent the sprocket and the chain from deviating. Early wear.

 5. Due to the high speed of the driving sprocket and the small number of teeth, it wears faster than the driven sprocket under the same conditions, which is a normal condition.

The thickness of the sprocket is standardized. If there is no special equipment for my processing, it is very wordy. The electromechanical market can buy ready-made ones. You only need to mention the model and number of teeth. The shaft hole of the ready-made sprocket is not machined to size. , As long as a small pre-hole is convenient for the user to cooperate, it is enough to process the shaft hole and key slot according to the needs of the shaft.

Comparison of sprocket drive and belt drive: chain drive is suitable for places where the two shafts are far apart, the uniform transmission ratio is required to be unchanged, but the requirements for the instant transmission ratio are not strict, and the working environment is harsh (oily, dusty, high temperature) and other places.

Sprocket

Application of sprocket: It is generally used in the mechanical transmission of metallurgy, light industry, chemical industry, machine tool, agriculture, lifting and transportation and various vehicles.

1. The tightness of the sprocket should be suitable. Too tight will increase power consumption and the bearing will be easy to wear; too loose the sprocket will easily jump and fall off the chain.The tightness level of the sprocket is: lifted or pressed down from the middle of the sprocket, about 2%-3% of the center distance between the two sprocket.

2. The sprocket should not swing or tilt when installed on the shaft.In the same transmission assembly, the end faces of the two sprockets should be in the same plane. When the center distance of the sprocket is less than 0.5 meters, it can be biased to 1 mm; when the center distance of the sprocket is more than 0.5 meters, it can be biased to 2 mm.But there can be no friction phenomenon of the sprocket tooth side. If the two wheels offset too much, it will easily cause chain disconnection and accelerated wear.It is necessary to pay attention to check and adjust the offset when changing the sprocket.

3. After the sprocket is severely worn, the new sprocket and the new sprocket should be replaced at the same time to ensure good meshing.It is not possible to just replace a new sprocket or a new sprocket alone.Otherwise it will cause poor meshing and accelerate the wear of the new sprocket or the new sprocket.After the tooth surface of the sprocket wears to a certain level, it should be turned over and used in time (referring to the sprocket with adjustable surface) to extend the use time.

4. The new sprocket is too long or stretched after use, and it is difficult to adjust. You can remove the chain link depending on the situation, but it must be an even number.The chain link should pass through the reverse side of the sprocket, the lock piece should be inserted outside, and the opening teeth of the lock piece should face the opposite direction of rotation.

5. The sprocket should be filled with smooth oil in time during work.The lubricating oil must enter the matching gap between the roller and the inner sleeve to improve working conditions and reduce wear.

6. The old sprocket cannot be mixed with some new sprocket, otherwise it is easy to produce an impact in the transmission and break the sprocket.

7. When the machine is stored for a long time, the sprocket should be removed and cleaned with kerosene or diesel oil, and then coated with oil or butter and stored in a boring center.
