Friction-type overload protection device of new servo system

Abstract

The invention discloses a friction-type overload protection device of a new servo system. The friction-type overload protection device comprises a turning box cover, a turning box and reducer box; one side of the turning box is provided with a turbine end cover, a steel wire guide wheel and a worm end cover, and the bottom of the turning box is fixedly connected with a reducer base; a turbine shaft is horizontally arranged in the turning box, one end of the turbine shaft is fixedly connected with a turbine, and the outer ring of the turbine shaft is provided with a turbine shaft sleeve; one side wall of the turning box is provided with a first deep groove ball bearing, and the turbine shaft is rotatably connected with the first deep groove ball bearing; the turning box is internally provided with a worm, the worm is in transmission connection with the turbine, and the end, extending out of the turning box, of the worm is fixedly connected with the reducer. The friction-type overload protection device is simple in design and convenient to operate, and the heat dissipation of the reducer can be well conducted, so that it is ensured that heat can be dissipated timely; when the steel wire guide wheel is subjected to larger resistance, the movement of the turbine and the worm can be stopped, and therefore the rotation of the steel wire guide wheel is stopped.

Description

technical field [0001] The invention relates to the technical field of protection devices, in particular to a frictional overload protection device for a new servo system. Background technique [0002] The servo system, also known as the servo system, is a feedback control system used to accurately follow or reproduce a certain process. The servo system is an automatic control system that enables the output controlled quantity of the object's position, orientation, state, etc. to follow any change of the input target (or given value). Its main task is to amplify, transform and regulate the power according to the requirements of the control command, so that the output torque, speed and position control of the drive device are very flexible and convenient. In machinery, when the shaft exceeds the load it can bear, the overload protection can prevent the damage of the equipment caused by overload.

Problems solved by technology

[0003] In the traditional structure, the wire guide wheel is driven to run through the worm gear transmission, and when the wire guide wheel is subjected to a large resistance, the motor will still drive the worm gear to move, thereby driving the wire guide wheel to run, which will make the wire guide Wheels and worm gears are subject to greater wear and tear during operation, reducing their service life, and the traditional worm gear generally only drives a wire guide wheel to run, which will lead to low work efficiency, high manpower and material resources, and the motor is working. At the same time, a lot of heat is generated. If it cannot be dissipated in time, it will cause a certain degree of damage to the motor and other components in the long run. For this reason, we need a new servo system friction overload protection device
