(Summary description)The tightness of the JIS sprocket should be appropriate. Too tight will increase power consumption and the bearings will wear out; too loose will easily jump and fall off the chain. Its tightness is: lifted or pressed down from its middle, about 2%-3% of the middle distance between two JIS sprockets.

Information

Do you know how to operate the maintenance knowledge of JIS sprocket? Let’s take a look at it with the editor below!
1. The tightness of the JIS sprocket should be appropriate. Too tight will increase power consumption and the bearing will be easy to wear; too loose is easy to jump and fall off the chain. Its tightness is: lifted or pressed down from its middle, about 2%-3% of the middle distance between two JIS sprockets.
2. There should be no swing and skew when installed on the shaft. In the same transmission assembly, the end faces of two JIS sprockets should be in the same plane. When the center distance is less than 0.5 meters, the deviation can be 1 mm; when the center distance is more than 0.5 meters, the deviation can be 2 mm. However, there must be no friction on the sides of the teeth. If the two wheels offset too much, it will easily cause chain disconnection and accelerated wear. When replacing, you must pay attention to check and adjust the offset.
3. After severe wear, a new JIS sprocket should be replaced at the same time to ensure good meshing. Only one end cannot be replaced, otherwise it will cause poor meshing and accelerate the wear of the new JIS sprocket. After the tooth surface is worn to a certain degree, it should be turned over and used in time (referring to the sprocket used with the adjustable surface) to extend the use time.
4. The new one is too long or stretches after use and 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 back of it, the locking piece should be inserted outside, and the opening of the locking piece should face the opposite direction of rotation.
5. JIS sprocket should be filled with lubricating oil in time during work. Lubricating oil must enter the matching gap between the roller and the inner sleeve to improve working conditions and reduce wear.
6. The old one cannot be mixed with some new ones, otherwise it is easy to produce shock in the transmission and break the JIS sprocket.
7. When the machine is stored for a long time, the JIS sprocket should be removed and cleaned with kerosene or diesel oil, and then coated with oil or butter and stored in a dry place.
The above is about its maintenance knowledge, I hope you can learn more.
