Abstract

The electromagnetism harmonic wave drive device relates to harmonic wave drive technique, it includes screw pair, bearing, seat and end cap; it also includes stator, flexible iron core, flexible wheeland steel wheel harmonic wave gear pair; flexible wheel is connected with screw pair; it uses magnetic field constructed by the stator and flexible iron core as drive, uneven function of rotated magnetic field makes flexible wheel and flexible wheel in steel wheel harmonic wave gear pair change with shape of cam, so period mesh is generated between flexible wheel tooth and steel wheel tooth to make flexible wheel rotate to drive screw pair rotate. The invention integrates motor, harmonic wave reducer and screw drive function, because without rotor and mechanical cam, it posseses characters that moment of inertia of system is little, starting current is little, response speed is fast, velocity ratio is big, precision is high, output form is direct line drive.

Description

technical field [0001] The invention relates to the technical field of harmonic drive, and relates to an electromagnetic harmonic drive actuating device. Background technique [0002] The usual actuating devices are hydraulic actuating cylinders, pneumatic actuating cylinders or screw mechanical actuating devices, etc., which need to be driven by motors or motor pressure pumps, or motor pneumatic pumps, which make the structure complex, bulky, and easy to operate. Not very accurate. Contents of the invention [0003] The purpose of the present invention is to disclose an electromagnetic harmonic drive actuating device, which does not use a high-speed rotating rotor and a mechanical cam, but uses a rotating magnetic field as power to perform external work. [0004] Another object of the present invention is to disclose an electromagnetic harmonic drive actuating device, which has the characteristics of small size, simple structure, small system moment of inertia, small sta...
