Abstract

The invention relates to a transmission mechanism overload protection device and belongs to the technical field of transmission devices. According to the device, power reflux is implemented through a gear shaft, a housing, a right half coupling, a left half coupling and a drive wheel shaft, and the motor power is returned to the drive wheel shaft through the gear shaft;when the drive wheel load is excessive, the power transmission between the drive wheel shaft and the motor is cut off through safety pin breaking, and the motor and the transmission mechanism are protected effectively. By means of the transmission mechanism overload protection device, transmission mechanism gearbox gears and the motor can be protected effectively, and the transmission system of entire experimental equipment can be protected; meanwhile, the axial size of the overload protection device is small, and occupied space of the experimental equipment is reduced; the transmission torque is large, and the modular design of the drive wheel shaft in the experimental system can be benefited by the power flux manner; the overload protection device is arranged outside the gearbox and is convenient to change, and system overload can be found conveniently.

Description

technical field [0001] The invention relates to the technical field of transmission devices, in particular to an overload protection device for a transmission mechanism. Background technique [0002] Motors, gearboxes, and transmission output shafts are commonly used power input modes in many mechanical structures. In this system, overloading will cause gear damage or motor burnout, which will lead to damage to the entire system, so people use various forms of overload protection. device to prevent damage to the transmission mechanism. Such as the Chinese patent application gear overload protection mechanism (public number: CN201110359Y), mainly consists of the skeleton plate of the gear shaft and the faceplate and snap ring with compression reed; the photoelectric integrated transmission safety protection device (public number: CN202007982U), including Pulley, safety clutch, photoelectric switch and detection block. The photoelectric switch is installed on the machine tool...
