Timing belt is a special kind of belt (with teeth) which is used to transfer rotary motion from one shaft to another.

We know that there are several methods by which we can transfer rotary motion of one shaft to another. For example, Gears, ropes, belts (without teeth) etc.

Timing belt is generally taken as a sub-type of belts. Timing belts carry accuracy of gears and cheapness of belts.

As we can see in above picture it contains teeth like gears which provides positive engagement with the pulley. Timing belts are used with special types of toothed pulleys which are specially designed for a particular timing belt.

Timing belt got its name from from its ability to transfer motion at the exact preset timing.

Advantages of timing belt

• Delivers precise motion with accurate timing
• Almost no vibrations produced
• No slip problem
• No noise generation which transferring g power
• Very high mechanical efficiency up to 98%
• No need of lubrication as compared with gears
• Very cheap as compared to gears
• No problem of rusting or corrosion
• Weight is less
• Safe to use

Applications of timing belt

• They are used with encoders
• They are used in cars, treadmills, sewing machines
