Abstract

In order to overcome the problem that the stability of a robot is affected by the rotating of an output shaft, which occurs after the existing steering engine is in a power outage state, the invention provides a steering engine. The steering engine comprises a motor, a speed reducing gear unit and a locking structure, wherein the motor is provided with a rotating shaft, and the speed reducing gear unit is connected with the rotating shaft and used for the speed reducing output of the motor; the locking structure limits the rotating of the rotating shaft when the motor is in the power outage state; and the locking structure relieves limitation on the rotating of the rotating shaft when the motor is in an electrified state. At the same time, the invention further discloses a robot with the steering engine. By adopting the technical scheme, the rotating shaft of the motor can be locked after the steering engine is in the power outage state, and the action keeping of the robot is facilitated.

Description

technical field [0001] The invention belongs to the technical field of motor reduction transmission equipment, and in particular relates to a steering gear and a robot. Background technique [0002] The steering gear is an important component to realize the function of the robot joint, which mainly includes basic components such as a motor, a control circuit board, a reduction gear set, an output shaft, and a sensor. The control method is as follows: setting a control signal, the control signal is transmitted to the motor through the control circuit board, the rotating shaft of the motor is controlled to rotate, and the torque is output through the output shaft after being decelerated by the reduction gear set. After the robot stops moving, the existing steering gear maintains the torque generated by the motor through continuous input current, so that the robot maintains the action when the motion stops. In some cases, such as the robot is powered off and the steering gear i...
