Gear reducer principle
Speed reducers are generally used in low-speed, high-torque transmission equipment . They reduce the speed of electric motors, internal combustion engines, or other high-speed power sources by meshing a smaller gear on the input shaft with a larger gear on the output shaft. Ordinary speed reducers may also have several pairs of gears operating on the same principle to achieve the desired speed reduction. The ratio of the number of teeth on the large gear to the number of teeth on the small gear is called the transmission ratio. (This means "reducing speed, increasing torque, and reducing inertia").
A speed reducer is a power transmission mechanism that uses gears to reduce the rotational speed of a motor to a desired speed while providing a larger torque. Speed reducers are widely used in mechanisms for transmitting power and motion.
Function of speed reducer
1. While reducing speed, increase output torque. The torque output ratio is calculated by multiplying the motor output by the reduction ratio, but care must be taken not to exceed the rated torque of the reducer.
2. Deceleration also reduces the load's inertia; the reduction in inertia is the square of the reduction ratio. You can see that most motors have an inertia value.
speed ratio of reducer
Speed ratio = Motor output speed ÷ Reducer output speed ("speed ratio" is also called "transmission ratio")
Formula for calculating the torque of a speed reducer
Gearbox torque = 9550 × motor power ÷ motor power input speed × speed ratio × operating efficiency (60%-96%)
