Embodiment 1

[0106] figure 1 It is a structural schematic diagram of the reduction gear transmission according to Embodiment 1 of the present invention. Such as figure 1 As shown, the deceleration device includes a servo controller 1, a servo motor 2 and a deceleration mechanism connected thereto. The deceleration mechanism is composed of a driving part and a driven part that cooperate with each other. In this embodiment, the driving part refers to the worm 4, and the driven part is The worm gear 8, the servo motor is connected with the worm 4 through the coupling 3, and the worm 4 cooperates with the worm gear 8 to input the power of the servo motor 2 and output it after deceleration. The input shaft of the servo motor 2 and the output shaft of the reduction mechanism are the worm shaft 7 A first position detection device 5 and a second position detection device 6 are respectively provided, and the first position detection device 5 and the second position detection device 6 input signals...

Abstract

The invention relates to a reduction gear and a control method thereof. The reduction gear comprises a servo motor and a reducing mechanism connected with the servo motor, the reducing mechanism comprises a driving part and a driven part mutually matched, and the servo motor is connected with the driving part through a coupler. The driving part and the driven part are matched to input the power of the servo motor and output the power after reduction. An input shaft of the servo motor and an output shaft of the reducing mechanism are respectively provided with a first detecting device and a second detecting device, the first detecting device and the second detecting device input signals to a servo controller, the servo controller controls the servo motor to drive the reducing mechanism so as to input the power of the servo motor and output the power after reduction. The reduction gear has low cost, high control precision and quick response; the torque and the rotating speed are controllable; networked and integrated control is conveniently realized; and instructions of a main controller can be received, and the operation of a mechanical arm is controlled in a closed loop mode.

Description

technical field [0001] The invention relates to a deceleration device and a control method of the deceleration device. Background technique [0002] The reducer is a power transmission mechanism that uses the speed converter of the gear to reduce the number of revolutions of the motor to the desired number of revolutions and obtain a larger torque mechanism. Reduce the speed and increase the output torque at the same time. The torque output ratio is the motor output multiplied by the reduction ratio, but attention should be paid not to exceed the rated torque of the reducer. The speed reduces the inertia of the load at the same time, and the reduction of the inertia is the square of the reduction ratio. You can look at the general motor has an inertia value. General reducers include helical gear reducers, including parallel shaft helical gear reducers, worm gear reducers, bevel gear reducers, planetary gear reducers, cycloidal pin wheel reducers, worm gear reducers, planet...
