如何计算Belt Drive
learn.whatIsHeading
Belt drive transmits power between shafts using flexible belt around pulleys. It's simple, quiet, and provides overload protection through slipping.
公式
Calculate: Speed ratio = D_driven / D_driver where D is pulley diameter
- D
- D value — Variable used in the calculation
分步指南
- 1Calculate: Speed ratio = D_driven / D_driver where D is pulley diameter
- 2Torque: T = P / ω (power divided by angular velocity)
- 3Tension and slippage determine power capacity
例题解析
输入
Driver 100 mm diameter at 1800 rpm, driven 200 mm
结果
Output speed = 900 rpm, 2:1 reduction
Torque doubles
常见错误注意事项
- ✕Over-tensioning belts (damages bearings)
- ✕Neglecting wrap angle effects on friction
常见问题
Why slip in belt drives?
Slight slip absorbs shock loads, protects driven equipment. Slip is normal (1-3%) and expected.
How do you prevent excessive slip?
Proper belt tension and friction material selection maintain power transmission.
