FAQ

  • In the early stage of design, what parameters need to be provided for selection?
    Need to provide: diameter range of large and small pulleys, speed ratio, small pulley speed, motor power or load, etc.
  • Choose a rubber timing belt or a polyurethane timing belt?
    Both have advantages, but the temperature resistance of rubber timing belts has better advantages, -40℃-90℃, wear resistance and other characteristics. Polyurethane material, no chipping, oil resistance, etc.
  • Can a special tooth shape be customized?
    This is possible. Generally, your company needs to provide detailed tooth profile drawings or samples for reference. You can apply for the production of tools and molds to meet the requirements of completing special tooth profiles.
  • Can OEM?
    Yes, you need to provide a copy of the valid trademark certificate with official seal, a copy of the business license with official seal and the original legal person authorization.
  • The belt is easy to slip, what should I do?
    You can check whether the center distance is too large, and adjust and reduce the center distance.
  • The belt is noisy, what should I do?
    Check the frame itself, check whether the belt is too tight.
  • Early rupture of synchronous belt
    1. The inertial force of the passive wheel and passive load is not considered.
    2. The load is too large or the passive wheel stops due to an accident. This greatly increases the load capacity.
    3. The pulley is too small. The belt is forcibly bent.
    Solution:1. Improve the design. 2. Check the design and replace it with a pulley with a smaller number of teeth than the original one. 3. Full attention and caution should be exercised during handling, storage and installation.
  • Timing belt edge wear
    1. The parallelism of the wheel is inaccurate.
    2. Insufficient bearing rigidity.
    3. The pulley rib is bent.
    4. The diameter of the pulley is smaller than the width of the belt.
    Solution: 1. Correct the positioning of the pulley. 2. Increase the rigidity of the bearing and fix it firmly. 3. Correct the rib or replace. 4. Check the design.
  • Timing belt tooth surface wear
    1. Excessive load.
    2. Excessive belt tension.
    3. Incorporates abrasive powder.
    4. Coarse teeth.
    Solution: 1. Improve the design. 2. Adjust the belt tension. 3. Improve the environment and increase the protective cover. 4. Trim the gear teeth or replace the pulley.
  • Timing belt teeth broken
    1. Jump teeth.
    2. Passive mechanical accident load increases.
    Solution: 1. Check the design. 2. Adjust the proper tension. 3. Increase the pulley diameter. Increase the number of meshing teeth. 4. Troubleshoot passive machinery
  • Timing belt with adhesive wear and cracks
    1. The rotation of the outer tensioner is blocked.
    2. The positioning of the outer tensioner is out of alignment.
    3. Touch the frame of the machine.
    4. Long-term low temperature.
    Solution: 1. Repair or replace the tensioner bearing. 2. Correct the tensioner position. 3. Check and correct mechanical parts. 4. Improve the ambient temperature.
  • Softened with adhesive
    1. High temperature.
    2. Tension pulley stopped.
    3. Stick with oil.
    Solution:1. Improve the ambient temperature. 2. Check and adjust the tensioner. 3. Do not stick to oil or change the oil-resistant timing belt.
  • Longitudinal cracks in the belt
    1. The timing belt runs beyond the edge of the pulley.
    2. The timing belt is wrapped around the rib of the pulley.
    Solution; 1. Adjust the position of the pulley. 2. Strengthen the bearing rigidity and fix it firmly.
  • Fragmentation of the tensile body part
    1. Improperly loading or unloading the timing belt.
    2. Incorporating foreign matter or sharp and sharp residues.
    Solution:1. Correctly install and remove the timing belt. 2. Improve the environment. Add protective cover.
  • Excessive noise during operation
    1. The tension of the timing belt is too high.
    2. Parallel misalignment of the two axes.
    3. The width of the timing belt is larger than the diameter of the pulley.
    4. The load is too large.
    5. The timing belt and pulley teeth do not fit properly.
    Solution:1. Reduce the tensioning wheel (no jumping teeth shall prevail). 2. Adjust the positioning of the pulley. 3. Improve the design. 4. Improve the design. 5. Check the timing belt and pulley.
  • Pulley tooth wear
    1. The load is too large.
    2. The tension of the synchronous belt is too large.
    3. The material of the pulley is not good.
    4. Incorporates abrasive dust.
    Solution:1. Improve the design. 2. Reduce the tension. 3. Use materials with high hardness, and the surface is hardened. 4. Improve the environment and increase the protective cover.
  • Maintenance of timing belt
    1. Inspection before use: Before using the synchronous belt, it is necessary to do a good job of inspection, and take corresponding measures for existing problems. This can effectively avoid the occurrence of failures caused by other problems during use, and the maintenance effect is very good.
    2. Avoid overload use: The synchronous belt should strictly follow the specified requirements during use, and try to avoid overload, otherwise it will easily lead to fracture and affect the service life.
    3. Do a good job of cleaning: When the synchronous belt is in use or not in use, you should actively do a good job in cleaning, otherwise the existing impurities or other stains will easily cause problems. This will also greatly shorten the service life.
    Although it is necessary to use the timing belt for maintenance work, the implementation of maintenance work needs to ensure that the method is correct, so that the expected effect can be achieved.
    The above is an introduction to the correct measures to maintain the synchronous belt, which will help to extend the service life of the belt better.
  • How to choose synchronous pulley?
    In the selection of synchronous pulleys, the material requires some high-speed home appliance industries. The selection of small pulleys is generally iron and other metal parts, and plastic and other materials are selected, which are easy to be damaged and cause the impact of transmission parts.
