Horizontal moving type engaging motor

Abstract

The invention provides a translatory engaging motor, comprising a rotor fastened with two cycloid internal ring gears, wherein, four pins in large gaps are perforated into four through holes on the rotor; two ends of the pins are fixedly connected with a casing, the rotor and the cycloid internal ring gears fixedly connected with the rotor can move in a certain range of radial direction relative to the pins, thereby forming a parallel four-bar motion constraining mechanism. A stator is coaxial with an output shaft, and four coil windings of the stator are electrified according to the predetermined sequence to generate electromagnetic force, thereby driving the stator to translate around the output shaft, driving the fixedly connected cycloid internal ring gears and cycloid external gears fixedly arranged on the output shaft to generate engaging motion, and outputting the autorotation of the cycloid external gears; and the rotation of the external gears are transferred to the output shaft through a connecting key to output the rotation with low rotary speed and large torque. The translatory engaging motor has the characteristics that an acceptance range between the stator and the rotor is shortened, and the acting force is increased through the engagement between the cycloid internal ring gears on the rotor and the cycloid external gears on the stator under the action of electromagnetic driving force, so that a reducer and a motor of a low-speed motor are integrated into a whole.

Description

technical field [0001] The invention relates to a motor with a novel structure, to be precise, it relates to a translational meshing motor composed of two parts: a component driven by electromagnetic force for translational movement of a magnet and a gear internal meshing reduction mechanism, which belongs to the driving force in a mechanical system. Component technology field. Background technique [0002] In recent years, some new progress has been made in the domestic research on the integration of the new reduction mechanism and the motor. For example, combining the design and manufacture of the motor and the harmonic reducer not only increases the output torque, but also significantly reduces its structural size. In foreign countries, especially in Japan, a variety of motors with different structures have been developed based on the principle of gear meshing reduction transmission. For example: a piezoelectric cycloidal motor, which converts the telescopic motion of t...

Moreover, the motors used in low-speed driving and heavy load situations need to be equipped with reducers and related components or devices, which naturally increases the weight of the driving device and the difficulty of installation.
