Abstract

The invention discloses a worm gear reducer which comprises an upper cover plate, a lower cover plate, a worm gear, a worm, an inner cam and an output sleeve. The upper cover plate and the lower cover plate are fixedly connected through a screw and a hexagon bolt. The worm gear and the worm are located in a containing space defined by the upper cover plate and the lower cover plate. An output shaft is arranged in the center of the worm gear. The worm is fixedly arranged above the worm gear. The worm gear and the worm are meshed. The two ends of the worm are fixedly provided with bearings respectively. One end of the worm is connected with a first connector and a second connector through one bearing. The inner cam is fixedly arranged on the worm wheel. The center of the inner cam is provided with the output sleeve. The output sleeve is matched with the output shaft. The output sleeve is provided with two pawls and a cam. The pawls are symmetrically arranged on the two sides of the cam. The output shaft is sleeved with the cam. The worm gear reducer is simple in structural principle, small in size, low in cost and capable of achieving output at the larger transmission ration, and the speed reduction efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of reducers, in particular to a worm gear reducer. Background technique [0002] The speed reducer plays the role of matching speed and transmitting torque between the prime mover and the working machine or the actuator. The speed reducer is a relatively precise machine. The purpose of using it is to reduce the speed and increase the torque. It is often used as a reduction transmission device between the prime mover and the working machine. It plays the role of matching the speed and transmitting torque between the prime mover and the working machine or the actuator to meet the work needs. It is also used for speeding up in some occasions. It is called a speed increaser. When selecting a reducer, it should be based on the selection conditions of the working machine, technical parameters, performance of the power machine, economy and other factors, and compare the outer dimensions, transmission efficiency, ca...
