An overload protection transmission device includes a transmission shaft having a mounting element provided at an end thereof, a disc-shaped fixing part rotatably fixed to the transmission shaft via the mounting element, an annular transmission gear, and a locking disc rotatably fixed to the transmission shaft and configured to rotatably couple the transmission shaft with the transmission gear. The transmission gear has an accommodating part and a friction part provided along an inner circumferential surface thereof. The accommodating part is configured to engage the fixing part when the fixing part is inserted into a central opening of the annular transmission gear. The locking disc includes an outer circumferential surface configured to engage the friction part of the transmission gear for transmitting a frictional torque between the locking disc and the transmission gear. |
