Speed reducer with threshold torque

Abstract

The invention discloses a speed reducer with a threshold torque. A movable mechanism and an output end assembling mechanism are installed on a planet speed reducer. The movable mechanism comprises a thrust bearing, a limiting sleeve and a spring. The thrust bearing, the limiting sleeve and the spring are matched and assembled together with a movable shaft. The output end assembling mechanism comprises an output block and an output shaft, the output shaft is sleeved with the movable shaft, an adapter block is installed on the output block through an adjusting screw, meanwhile, the movable shaftis blocked, and an output shaft of the speed reducer and the movable shaft are engaged or disengaged, the distance between the adapter block and the output block is adjusted through the adjusting screw, the spring is compressed, the friction positive pressure between the movable shaft and the output shaft of the speed reducer is adjusted, and the threshold torque is controlled. According to the speed reducer with the threshold torque, on the basis of the threshold torque, the output shaft of the speed reducer and the movable shaft are constantly engaged or disengaged, a sound and an alarm aregiven, the threshold torque can be adjusted according to the requirement of a client, the torque is read through a pointer, the speed reducer is simple in structure, convenient to operate, low in cost and capable of being used for mechanical transmission, and the problems of broken shafts, damaged teeth and damaged motors caused by the excessively-large torque are avoided.

Description

technical field [0001] The invention belongs to the technical field of mechanical transmission, and in particular relates to a speed reducer with threshold torque. Background technique [0002] With the advancement and development of transmission technology, equipment has more and more stringent requirements for transmission torque, and high torque is almost a necessary condition in the transmission process. After a hundred years of development, the structure of planetary reducers has become increasingly fixed, and rigid transmission must rely on the quality of materials. strength. However, at present, the development of material strength of low-cost steel is stagnant, the structure is fixed, and the limitation of material strength makes the reducer appear in an unexpected situation. Teeth and other phenomena, and the greater the required torque, the larger the reducer, and the greater the cost of replacement parts. In addition, in actual industrial production, due to hars...

Problems solved by technology

However, at present, the development of material strength of low-cost steel is stagnant, the structure is fixed, and the limitation of material strength makes the reducer appear in an unexpected situation. Teeth and other phenomena, and the greater the torque required, the larger the reducer and the greater the cost of replacement parts

In addition, in actual industrial production, due to the harsh production conditions, the reducer is often overloaded. In many cases, the customer is overloaded without knowing it, and there is no preload.
