High performance electromechanical driving mechanism

Abstract

Provided is an electro mechanical driving mechanism with high performance comprising a speed reducer component, an output driving device, a servo motor and a casing. The servo motor includes a hollow rotating shaft (1). The speed reducer component includes an eccentric cam (7), an input gear (10), a fixed gear (11), an output gear (12). The output device includes a hollow output shaft (22). The driving mechanism integration designs the speed reducer component, the output driving device and the servo motor to ensure concentricity precision from structure, the eccentric cam (7) drives the input gear (10) to generate appropriate eccentric rotation so as to realize few teeth difference speed reducing precise driving, the taper shaped eccentric cam organically combines with a round arc spiral bevel gear to form a precise drive pair so as to realize none side clearance driving and self-adaptive teeth surface wearing compensation. The present invention has advantages of high precision, long service life, large torque, low engergy consumption and light weight, can be widely applied in engineering field such as robot, automatization, avigation, spaceflight, and weapon equipment.

Problems solved by technology

[0002] For a long time, the driving motor and the reduction mechanism in mechanical equipment have been designed separately, so it is inevitable to consider the connection design between them, and the shaft alignment error. When the transmission mechanism is worn, automatic compensation cannot be realized, and a large backlash transmission, and the transmission torque is small, the weight is heavy, and the structure is complex

For example, planetary reducers, cycloid reducers and RV reducers have complex structures, poor manufacturability, increased structural size, high manufacturing and processing requirements, high production costs, difficult installation and debugging, large additional dynamic loads, especially large transmission High power, vibration and noise

Under the long-term alternating load, the flexible spline in the harmonic drive is prone to fatigue wear failure, and cannot realize automatic wear compensation, and the size of the positioning center hole of the harmonic reducer is difficult to be consistent with the joint design, which restricts the use of this transmission mode Application on integrated intelligent joints

As a result, there are relatively large friction, wear, vibration, noise, reactive power consumption and other problems in mechanical equipment, as well as major problems in vibration and noise reduction in weapons and equipment; on the other hand, it also causes the comprehensive performance and reliability of mechanical transmission systems Poor performance, shortened service life of equipment, etc.
