The reduction ratio, also known as the transmission ratio of a speed reduction device, is a type of transmission ratio. It refers to the ratio of the instantaneous input speed to the output speed in a speed reduction mechanism . The maximum reduction ratio for a single-stage WP series speed reducer is 1/60, and for a single-stage RV series speed reducer, it is 1/100. So how are these reduction ratios derived, and how should we calculate them? There are several methods for calculating the reduction ratio of a speed reducer:
1. Definition of calculation method: Reduction ratio = Input speed / Output speed.
2. General calculation method: Reduction ratio = Operating torque / 9550 / Motor power / Input speed / Operating coefficient, MB continuously variable transmission usage precautions.
3. Calculation method for reduction ratio of belts, chains and friction wheels: Reduction ratio = driven wheel diameter / driving wheel diameter. How to add lubricating oil to helical gear reducers and cycloidal pinwheel reducers.
4. Gear system calculation method: Reduction ratio = number of teeth of driven gear / number of teeth of driving gear (If it is a multi-stage gear reduction, then the number of teeth of the driven gears of all meshing pairs of gear sets / the number of teeth of the driving gear, and then multiply the results, NRV reducer).
