Translational gearing motor with improved structure

Abstract

A translational gearing motor with improved structure is a low-speed large-torque motor integrating a motor with a speed reducer. 4 sets of magnetic poles are arranged in the axial direction, each setof magnetic poles consists of a rotor in the middle and stators at two sides, a coil winding is arranged on the stator, and after being electrified, the winding drives the rotor to move left and right so as to form a unidirectional drive magnetic pole. The four sets of magnetic poles are divided into two pairs with the installation directions vertically intersecting. A slide bush and a main shaftof a through hole in the middle of the rotor form a slide revolute joint and the main shaft is connected with a cycloid external gear through a connecting key. By controlling the working status of the windings of the four sets of magnetic poles, the rotor can be driven to drive the main shaft to generate translation of revolution mode in radial direction and to drive the cycloid external gear anda cycloid annular gear fixed on a machine shell to do gearing motion. According to theory of engagement, the cycloid external gear drives the main shaft to output low-speed large-torque motion. The motor is characterized by not only improving the winding fill rate of a single magnetic pole, but also reducing the control difficulty of magnetic field force of distributed windings by arranging a plurality of unidirectional drive magnetic poles in axial direction.

Description

technical field [0001] The present invention relates to a structure-improved translational meshing motor, to be precise, to a structure-improved reluctance change between the stator and the rotor, which converts electrical energy into mechanical energy, and then replaces the original hole pin structure with a cross Under the restraint of the sliding constraint pair of the slider, the rotor makes the translational movement around the stator, and the rotor drives the translational meshing motor of the internal meshing gear reduction mechanism, which belongs to the technical field of electric drive devices in the mechanical equipment system. Background technique [0002] In recent years, good progress has been made in the research on the integration of the new reduction mechanism and the motor at home and abroad. For example, the motor and the harmonic reducer are combined to design and manufacture, so that the output torque is increased, and its structural size is significantl...

Problems solved by technology

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

For this reason, the applicant has developed a translational meshing motor (patent application number: 200810114840.5) that integrates the gear reduction device and the motor driver, which better solves the above-mentioned various defects of the prior art, but later In the process of use, it is found that there are still defects in its structure: its magnetic field is easy to couple and generate a negative power magnetic circuit, the circuit control is relatively complicated, and the precision of machining and assembly of individual parts is high. Therefore, how to improve the above motor to improve and improving its electromechanical comprehensive performance has become a new research topic for the applicant
