Abstract
The utility model relates to a center-transmission mud scraper overload protection device for preventing torque from overload in a mode of torque value monitoring, namely an automatic control device of a torque value. The aim is to prevent excessive loads to damage a transmission mechanism. In order to realize the purpose, a torque measuring device (4) is installed between a motor (6) and a speed changer (3), and a torque signal is sent to a programmable controller (5) to control the turning on/off of the motor (6). In working, working resistance torque is first transferred to a rotary fulcrum bearing (1), is transferred to the speed changer (3) by the rotary fulcrum bearing (1) and then is transferred to the torque measuring device (4). The resistance torque is output to the programmable controller (5) by a torque sensor (42), and the rated load of the speed changer (3) is set in the programmable controller (5) to control the motor (6), so that a driving device is prevented from overloading, and a mud scraper is protected. The torque sensor (42) is connected with the speed changer (3) by an involute spline pair (44), and power is transferred smoothly.
