Gear reduction for belt
« on: December 16, 2007, 10:54:36 PM »
If I'm using belt and pulley, does the gear reduction formula apply in this case too?

Note: one pulley is 5cm diameter (connected to the motor)
         The other is 10 cm diameter (connected to the application)

Make sure you measure the diameter of where the belt rides, not the outside diameter of the pully that includes the flange.

offcourse it does, only the direction will be different.

What type of belt (v-belt, timing belt, etc)?

Are there high dynamic loads?

I ask because unlike gears, you may need to account for slip.

kennykck, I noticed a lot of gear related questions from you. Building something interesting? :P

I'm using timing belt. High dynamic load? not sure bout that. So account the slip with how many percent?

So... I gets ur attention. ;D I'm doing this stuff

Timing belts won't have slip, so don't worry about that.

However belts stretch, such as if you have a high load, or high dynamic load (high acceleration).

If you are building a robot arm with this, it will reduce the positional accuracy a bit.
