Timing Belt (Toothed belt) Advantages And Disadvantages

Timing Belt Advantages And Disadvantages image
The timing belt is an example of the synchronous drive. They have teeth molded on the inner surface that fit into matching toothed pulleys. This positive drive belt has no slippage. So they are used in timing purpose, stepping motors. They can deliver higher power than a flat belt with speed up to 50 m/s for small pitch belts.

Advantages of timing belt drive

  • High torque carrying capacity.
  • No slipping between the belt and pulleys.
  • Power transmission at a constant speed.
  • Virtually no creep.
  • Low noise and vibration.
  • Lubrication not required.

Disadvantages of timing belt drive

  • They are not economical.
  • Need a sophisticated design of the belt as well as the pulley.
  • Clutch action not possible.
  • No protection against overloading.
