[0002] A precision reducer is a power transmission mechanism that uses a gear speed converter to reduce the number of revolutions of the motor to the desired number of revolutions and obtain a larger torque. A precision reducer is a relatively precise machine. Its purpose is to reduce the speed and increase the torque.

[0003] After searching, the existing patent (publication number: CN220523265U) discloses a micro-backlash precision reducer for industrial robots, which relates to the field of precision machinery technology, including a casing, a motor is installed on the side end of the casing, the internal output end of the motor is connected to a shaft, the side end of the shaft is sleeved with a bearing, and the outer sleeve of the shaft is sleeved with a driving gear. The left and right side wall surfaces of the casing are fastened with sound-absorbing panels through elastic rods. Under the action of the rotating shaft, the auxiliary gear is installed and sleeved, and the tooth angle edge of the outer wall surface of the auxiliary gear is meshed with internal teeth, and external teeth are arranged on the outside of the internal teeth, and the external teeth and the driving gear are meshed and connected, so that the structure forms an internal and external gear structure, which is convenient for further reducing the rotation speed of the driving gear, so that the large backlash factor of the overall reducer is reduced, and the performance of the reducer is effectively further improved. At the same time, the overall manufacturing cost is reduced by 30% compared with the conventional reducer, ensuring the service life of the overall device.

[0004] However, there are still some shortcomings in the above structure. The industrial robot uses a micro-backlash precision reducer to transmit information using gears. Due to the gap between the gears, the accuracy will be limited. Using existing high-precision reducers on the robot will greatly increase the cost.

[0005] Therefore, it is necessary to provide a new stable operation robot with precision reducer to solve the above technical problems. Utility Model Content

[0013] As a further solution of the utility model, the material of the twisted rope is polyarylate fiber, and the other end of the twisted rope is fixedly connected to the T-shaped clamp tube.

[0014] Compared with the related art, the stable operation precision reducer for robots provided by the utility model has the following beneficial effects:

[0015] 1. The utility model sets a deceleration mechanism, and starts the servo motor to drive the rope to roll out and drive the reduction wheel and the output wheel to do reciprocating swinging motion, thereby stably driving the operation of the robot.

[0028] like Figure 1 and Figure 4 As shown, the fixing plate 15 is provided with an avoidance groove 17, and the outer surface of the reduction wheel 11 is provided with a limiting groove 18;
