Good day all,
I am a student doing a design project on timing belt and pulley with design considerations.
I need to achieve a position accuracy of 1mm. Initially, i thought that a 1mm pitch will do the job, but apparenatly, the pitch and the position accuracy is two different issue. I am very confused of how to achieve it.
Do i need to find a smaller pitch size pulley? (I tried searching but to novalid.)
My current design
Given Centre Distance = 1500mm
Calculated Minimum Diameter of pulley = 3.074mm
Ideally Gear ratio: 1:1
Would apperciate if someone would give me some light about it. Thanks
Surely the position accuracy is not so much a function of the belt but more to do with the stepper motor angular movement ? or whatever is driving the belt.
Also you don't say where the required accuracy has to be measured ? belt position, driven ball screw, item connected to ball screw via ball nut, etc.
