Micro-cultivator V-belt

Possible causes:
1. V-belt use time is too long, the material aging
2. The transmission device design is unreasonable, resulting in the V-belt to bear too much tension
3. Improper installation, resulting in partial wear or vibration during operation

Possible causes:

1. Excessive tension
2. The mechanical equipment speeds up instantly to reach the transmission peak, causing the shaft to be pulled off, the  active and passive wheels are not parallel, and the transmission Angle is generated
3. Mechanical installation error leads to the main and passive wheels are not parallel
4. The section Angle of the belt groove is wrong and asymmetrical

Solution:

1. Readjust the tension force to the recommended conforming value
2. Mechanical equipment is strictly prohibited from speeding up initially, and uniform speed is adopted
3. Control the installation error and correct the parallel of the active and passive wheels
4. Measure the pulley groove Angle and replace the faulty pulley

Possible causes:

1. Use tools to pry, causing damage to the cord
2. There is foreign body intrusion during operation, resulting in instant collapse
3. The transmission system of the device is stuck
4 Belts are not installed according to the designed number
5. Severe impact load or sudden excessive load

Solution:

1. Loosen the fixing bolts of the power end to reduce the center distance, and install in the state of no forced force
2. Install protective cover to prevent foreign matter from entering
3. Stop the device to rectify the fault
4. Install the belt according to the design number
5. Redesign according to impact load; Balanced start equipment to prevent sudden load

Possible causes:

1. Tension is too low
2.The environment is too high or too low
3. Contaminated by chemicals
4. Pulley diameter is less than recommended value

Solution:

1. Readjust the tension force to reach the conforming value
2. Eliminate or block heat sources, improve ventilation and cooling, and use anti-high temperature and anti-low temperature V-belts
3. Protect the V-belt from chemical pollution, using special structure triangle belt
4. Replace the belt wheel with the required diameter

Different models, length of the V-belt length deviation range is different, the implementation standard for the national standard GB/T11544, round mold (below 2700 length) production can meet the use of the matching group, plate (above 2701 length) production needs to be clear matching requirements, measuring the length of the matching group after delivery.

Possible causes:

During the initial installation of the new equipment, pulley finish is too low, causing the V-belt and the belt pulley to rub off the black powder

Solution:

Need to improve pulley finish

Possible causes:

1. The adhesive strength of the production of immature vulcanized cloth and bottom adhesive is not enough
2. The performance of the V-belt does not match the requirements of the equipment and cannot meet the requirements of the equipment transmission

Solution:

1. Replace the qualified product
2. Re-select the product whose v-belt performance matches the equipment requirements

Possible causes:

1. The wheel groove is invaded by foreign bodies
2. Belt wheels are not aligned
3. Large tolerance and inconsistent length
4. The tension force is too low, the force is uneven and partial wear
5. Uneven force caused by uneven distribution of wire and rope in the production process leads to overturning
6. The belt wheel does not match the V-belt
7. Pulley diameter is less than the recommended value

Solution:

1. Add protective cover to clear foreign bodies
2. Recalibrate the alignment of the pulley
3. Measure and confirm the matching before installation to ensure that the length of the V-belt is consistent
4. Repair the tensioning device components and re-tensioning
5. Replace the triangle belt
6. Re-select belt and pulley
7. Replace the pulley with the proper diameter

Possible causes:

The tension force of the V-belt is insufficient, the surface of the belt groove is worn or polluted, and the transmission ratio is not matched.

Solution:

Adjust the tension of the V-belt to make it reach the specified value; Detect and replace worn or contaminated pulley grooves; adjust or replace the transmission system to match the transmission ratio.

Possible causes:

It is usually caused by the friction between the V-belt and the belt groove, the transmission system imbalance or improper installation.

Solution:

Detect and replace the V-belt and pulley groove with serious friction damage; Adjusting the balance of the belt; Follow the correct method of installation to ensure that the clearance between the V-belt and the wheel groove is appropriate.

Belt selection needs to include the power of the equipment, speed, diameter of the main/passive wheel, startup frequency, and whether there is a tension wheel.

Trademark specifications, smells

The temperature range of the belt is determined by the belt rubber type natural rubber (-30~70℃), neoprene rubber (-40~85℃), EPDM rubber (-40~120℃)
