Daily Maintenance Guide for Double Row Sprockets

The daily maintenance guide for double row sprockets should take into account their structural features, usage environment, and relevant maintenance requirements. It starts from aspects such as cleaning, lubrication, inspection, and adjustment to ensure the normal operation of the equipment and extend its service life. The following is a detailed explanation:

1. Cleaning and Inspection

Regular cleaning: During use, regularly clean the dirt, dust, and impurities on the surface of the sprocket to avoid increased wear or poor lubrication caused by contamination. You can use a neutral cleaner to wipe the tooth surface of the sprocket and then dry it with a clean cloth.

Check the wear condition: Regularly inspect the wear degree of the tooth surface of the sprocket, especially the tooth tips. If excessive wear or deformation is found, replace the sprocket in time.

Check the tightness: Ensure that the tightness of the sprocket is appropriate. Being too tight will increase power consumption and accelerate bearing wear, while being too loose may cause the chain to skip and accelerate wear. Usually, you can check the tightness by lifting or pressing the middle of the sprocket, keeping it within 2% - 3% of the center - to - center distance between the two sprockets.

2. Lubrication and Maintenance

Timely lubrication: During operation, add lubricating oil in a timely manner. In particular, the lubricating oil should enter the matching gap between the rollers and the inner sleeve to reduce friction and wear.

Choose the right lubricant: Select dry or liquid lubricants according to the working environment and equipment type to ensure that all chain and sprocket components are covered. Avoid using oils with too high viscosity to prevent clogging of the friction surface.

Regularly replace the lubricating oil: For newly - started equipment, it is recommended to replace the lubricating oil every 250 hours. Then, adjust the replacement cycle according to the operating status of the equipment.

3. Installation and Adjustment

Correct installation: The sprocket should be installed smoothly on the shaft. The end faces of the two sprockets in the same transmission assembly should be in the same plane, and the deviation should be controlled within a reasonable range (for example, the deviation should not exceed 1 mm when the distance is less than 0.5 meters). Avoid skewing or swinging, as this will affect meshing and accelerate wear.

Adjust the tension: After using a new chain, it needs to be evenly stretched. Ensure that after the connecting rod passes through the chain, the locking tabs are inserted into the outside and the opening directions are opposite. At the same time, regularly check the tension of the chain to avoid it being loose or too tight.

4. Replacement and Maintenance

Replace old parts in time: When the sprocket is severely worn, replace it with a new one in time. Do not mix old and new sprockets, as this will generate impact forces, to unstable transmission and even damage.

Precautions for long-term storage: If the equipment is not used for a long time, disassemble and clean the sprocket, apply engine oil or butter, and store it in a dry place.

5. Other Precautions

Avoid excessive impact: Prevent the sprocket from bearing excessive impact and vibration, as this will accelerate wear and shorten its service life.

Prevent corrosion: Avoid direct sunlight, rain, and contact with corrosive chemicals, especially for stainless-steel sprockets.

Regular maintenance plan: It is recommended to formulate a regular maintenance plan, such as checking the appearance daily, cleaning and lubricating weekly, and inspecting the wear condition monthly.

Through the above measures, the service life of the double row sprocket can be effectively extended, and the operating efficiency and stability of the equipment can be improved. At the same time, you should strictly operate according to the requirements of the equipment manual and adjust the maintenance frequency and methods according to the actual usage situation.
