How does a gear reducer work? Basic principle: When the output speed of the motor is input from the drive shaft, the pinion gear is driven to rotate, and the pinion gear drives the large gear to move.The large gear has more teeth than the small gear, and the speed of the large gear is slower than that of the small gear, and then the output is output from the shaft (output shaft) of the large gear, thus playing the role of output deceleration. Let me talk about the purpose of the reducer first: the reducer is generally used to convert the higher speed output by the motor into a lower speed through the gear set.While reducing speed, torque increases.In the practical application of electric transmission, some equipment or parts have specific speed, torque and output direction, so a reducer is needed to complete this function.According to the output direction, it is divided into: the input shaft is parallel to the output shaft, the input shaft is perpendicular to the output shaft, and the bevel gear reducer belongs to the latter. What is the difference between a gear reducer and a worm gear reducer? Different transmission methods, the gear reducer adopts gear transmission, including straight teeth, helical teeth, herringbone teeth, etc.; the worm gear reducer is decelerated by a worm gear pair (worm gear and worm).The input and output of the gear reducer are parallel (except for bevel gears).The input and output of the worm gear reducer are generally cross (90 degree) gears, which will not lock themselves without external force.When the conditions are met, the worm gear can be self-locking.Other factors include different efficiencies, coefficients of friction, etc.
