Abstract: speed ratio of reducer, refers to the use of mechanical reducer, we rated speed nN (r/min) and the speed of the reducer output shaft nL ratio called speed ratio I (also known as transmission ratio), I =nN/nL. Deceleration ratio calculation method: suppose: motor rated work...

Speed ratio of hard gear reducer

Speed ratio of reducer, refers to when the use of mechanical reducer, we rated speed of the motor nN (r/min) and speed of the reducer output shaft nL ratio called speed ratio I (also known as transmission ratio), I =nN/nL.

Calculation method of deceleration ratio:

Suppose: the rated power of the motor is P (kw), the rotation speed is n1 (r/min), the total transmission ratio of the reducer is I, and the transmission efficiency is u. Then: output torque =9550*P*u* I /n1 (N.m)

1. Define calculation method: deceleration ratio = input speed ÷ output speed.

2. General calculation method: deceleration ratio = torque ÷9550÷ motor power input torque ÷ working coefficient,MB stepless variable speed machine

Speed ratio of hard gear reducer

3, gear system calculation method: reduction ratio = the number of driven gear teeth ÷ the number of active gear teeth (if it is a multistage gear reduction, then the number of driven gear teeth ÷ the number of active gear teeth of all the meshing pair of gear sets, and then the result can be multiplied,NRV reducer.

4. Calculation method of reduction ratio of belt, chain and friction wheel: reduction ratio = the diameter of the driving wheel ÷ the diameter of the driving wheel, spiral gear reducer and cycloid needle wheel reducer how to add lubricating oil.
