Choice of belts and pulleys
2.Choice of belts and pulleys
(1)Choice of belt thickness
- Power transmission belt: Thickness 0.04 to 0.1mm, Width 10 to 40mm
- Conveyor belt for light-weight workpieces: Thickness 0.08 to 0.2mm, Width 10 to 50mm
- Conveyor belt for light-weight workpieces: Thickness 0.1 to 0.5mm, Width 10 to 500mm
- Conveyor belt for heavy-weight workpieces: Thickness 0.6 to 1.2mm, Width 200 to 1500mm
(2)Choice of pulley diameter
- Pulley Diameter for DR type belts =Belt thickness (t) X 400 or more
- Pulley Diameter for DW type belts =Belt thickness (t) X 700 or more
In power transmission choice of pulley diameter is;
- Pulley Diameter for DR and DO type belts = Belt thickness (t) X 400 or more
Please fill in questionnaire for belt stress calculation in power transmission and conveyors.
(3)Edge positioning
(1)Crown pulley
Crown pulley prevents belt wandering.
