The Usage Essentials and Daily Maintenance of Rubber v Belts

Key points for using rubber v belts

1. Installation: before installation, if the Centre-to-centre distance between the two shafts is adjustable, the Centre-to-centre distance should be shortened first, and the Centre-to-centre distance should be adjusted as required after the tape is installed; If the Centre-to-centre distance between the two shafts is not adjustable, put one V-belt into the groove of one pulley, and then rotate the other pulley to install the V-belt. Use the same method to install the remaining triangular tape. During installation, it is prohibited to use tools to forcefully pry or pull the triangular tape to prevent it from being stretched or damaged.

2. Staining prevention: the rubber v belt shall be strictly prevented from being stained with oil and muddy water during use, and shall not contact with Corrosive substance such as acid and alkali, so as to prevent damage caused by slipping and corrosion of the triangular belt.

3. Prevention of slotting: When installing the pulley, the centers of the two pulleys need to be aligned, otherwise it will cause the triangular belt to work unilaterally and accelerate wear, shortening the service life of the triangular belt.

4. Mixing old and new belts: When replacing a group of two or more triangular belts, the same model of triangular tape should be used, and the tightness of each group of triangular belts should be consistent. Mixing old and new belts or reducing the number of belts should not be used. Otherwise, the force on the new and old triangular belts will be uneven, and even the old triangular belts will not work, affecting power transmission and shortening the lifespan of the triangular belts.

5. Suitable tightness: If the triangular belt is too loose, it can easily slip and increase wear, even causing poor power transmission; Being too tight not only causes. The triangular belt is stretched and deformed, which is prone to damage, and may also cause excessive force on the engine main bearings and clutch bearings, accelerating the wear of the triangular belt. The method to check the tightness of the tire is to apply a vertical pressure of about 2kg by hand in the middle of each tape, with a sinking amount of 20-30mm. If it is not suitable, it should be adjusted promptly.

6. Purchase: The triangular belt selected according to the standard model should be compatible with the pulley groove, otherwise, the triangular belt will not work properly in the pulley groove. When replacing with triangular tape, bring the old tape to the agricultural machinery department to purchase to prevent the wrong model.

7. Daily maintenance: When driving agricultural machinery, the operator should master the correct operating skills, follow the technical requirements of the user manual, and try to avoid sudden starting and sudden braking; Frequent overload operations should also be prevented; The triangular belt should be removed and stored separately when the machine is out of use for a long time.

What are the daily maintenance methods for triangular belts?

1. Correct selection

The commonly used joint v belts come in different models. When replacing, it is necessary to ensure that the groove model of the original joint triangular belt or pulley is consistent, and the length of the replaced belt should also be consistent with the original length.

2. Correct installation

When installing the belt, the symmetrical center plane of the groove of the main and secondary pulleys of the unified circuit shall be in the unified plane, and the positional deviation shall not be greater than ± 3% of the Centre-to-centre distance. Otherwise, it will cause the combined triangular belt to twist in the wheel groove, causing early wear on the side and reducing its service life.

3. Daily maintenance

Strictly monitor the operation of the triangular belt during use, check for any abnormal vibrations, and carefully listen for any abnormal noise. After running for a period of time, turn off the machine and check the heating of the bearings and motors.

4. Clean the belt and pulley

Wipe the triangular belt with a cloth dipped in a small amount of non volatile liquid. Do not soak in cleaning agents or use cleaning agents to brush the belt. Do not use sandpaper or sharp objects to scrape the belt.

5. Clean oil stains

After the triangular belt is stained with grease, engine oil, and other oil stains, it is easy to slip and accelerate the damage of the belt. It should be cleaned in a timely manner with gasoline or with cleaning agents such as alkaline water, and oil cannot be used for operation.

Triangle belts are widely used in agricultural machinery. During operation, they are prone to getting stuck in grease, engine oil, and other oil stains, which can lead to slipping and exacerbate belt wear. So, how can dirty triangular belts be cleaned?

1. Do not use gasoline, benzene, Turpentine, etc. for cleaning.

2. Cleaning agents such as alkaline water can be used for cleaning, and attention should be paid not to work with oil.

3. When cleaning the rubber v belt, use warm water instead of cold and hot water.

4. Avoid getting contaminated with mud, water, and oil during the use of triangular belts. Once contaminated with oil, it should be cleaned promptly with soap and water.

5. Alternatively, a mixture of 1:10 glycerol and methylated alcohol can be used for cleaning.

The above are several methods for cleaning triangular belts. I'm not sure if everyone has learned them yet. Also remind everyone to avoid contact with sharp objects, wire brushes, sandpaper, and other objects when using triangular belts, as they may cause damage to the belt.
