Cylindrical gear reducer is a power transmission mechanism. By using the speed converter of gear, the rotation number of motor is reduced to the desired number of turns, and the mechanism with larger torque is obtained. The cylindrical gear reducer is generally used for the transmission equipment with low speed and large torque, which can drive the motor, The power of internal combustion engine or other high-speed operation can reduce speed by engaging the large gear on the output shaft with fewer teeth on the input shaft of the reducer. The common cylindrical gear reducer will also have several pairs of gears with the same principle to achieve the ideal deceleration effect. The ratio of the number of teeth of the large and small gears is the transmission ratio.
Series is the number of sets of cylindrical gear. Because a set of planetary gears cannot meet the larger transmission ratio, sometimes 2 sets or 3 sets are needed to meet the requirements of supporting the larger transmission ratio. Because of the increase of the number of planetary gears, the length of the two or three-stage reducers will increase and the efficiency will decrease. For structural reasons, the single-stage deceleration is 3, and the large gear reduction is generally no more than 10, The common deceleration ratio is: 3, 4, 5, 6, 8, 10. the series of reducers generally does not exceed 3, but some of the large speed reduction ratios have four stages.
