Calculation method of reduction ratio of reducer 　　The concept of reduction ratio: the transmission ratio of the reduction device, which is a kind of transmission ratio, refers to the ratio of the instantaneous input speed to the output speed in the reduction mechanism, which is represented by the symbol "i".If the input speed is 1500r/min and the output speed is 25r/min, then the reduction ratio is: i=60:1.Generally, the reduction ratio of the reduction mechanism is marked with the actual reduction ratio, but some special reducers such as cycloid reducers or harmonic reducers are sometimes rounded up without the denominator. For example, the actual reduction ratio may be 28.13. When labeling, it is generally labeled 28.
　　Calculation method of reduction ratio
　　1. Define the calculation method: reduction ratio = input speed ÷ output speed.
　　2. General calculation method: reduction ratio = use torque ÷ 9550 ÷ motor power × motor power input revolutions ÷ use coefficient.
　　3. Gear system calculation method: reduction ratio = number of driven gear teeth ÷ number of driving gear teeth (if it is a multi-stage gear reduction, then the number of driven gear teeth of all meshing pairs of gear sets ÷ the number of driving gear teeth, and then the result will be obtained Just multiply. 
　　4. Calculation method of reduction ratio of belt, chain and friction wheel: reduction ratio = driven wheel diameter ÷ driving wheel diameter. 
　　For the selection of miniature and small gear reducers, customers only need to inform the required operating speed, and our professionals will select the appropriate speed ratio according to the customer's working conditions.
