The term Gear Ratio is used to calculate the speed and torque of output gear when torque is applied to the input gear. In this guideline the torque … A gear is made up of toothed wheels ("teeth") connected to shafts. To calculate speed ratio, otherwise known as gear ratio, you divide the number of teeth of the input gear by the number of teeth of the output gear. Torque can be defined asthe tendency of a force to rotate an object about an axis and is estimated by multiplying the distance (the distance from the pivot point to the area where force is applied) and that force applied. There are two torque parameters used to define a BLDC motor, peak torque (T P) and rated torque (T R). If any two of the three variables are known, the other can be calculated. The gear ratio expresses the ratio of the output torque to the input torque. Torque - Horsepower (hp) conversion is a method of converting one unit from other and vice versa. and also if speed of input pneumatic motor varies +-300rpm. Formula. GR is the gear reduction ratio.
