High performance electromechanical driving mechanism

Abstract

A high-performance electromechanical drive mechanism, including a reducer assembly, an output transmission device, a servo motor and a casing, the servo motor includes a hollow shaft (1), the reducer assembly includes an eccentric cam (7), an input gear (10), a fixed gear (11), output gear (12), the output device comprises a hollow output shaft (22). The driving mechanism integrates the design of the reducer assembly, the output transmission device and the servo motor to ensure its concentricity accuracy in structure, and drives the input gear (10) to produce moderate eccentric rotation through the eccentric cam (7), realizing the precise transmission of deceleration with less tooth difference ;The conical eccentric cam and the arc spiral bevel gear are organically combined into a precision transmission pair to realize backlash-free transmission and self-adaptive tooth surface wear compensation, with high precision, high reliability, long life, high torque, low energy consumption, With the advantages of small size and light weight, it can be widely used in engineering fields such as robotics, automation, aviation, aerospace, and weaponry.

AI Technical Summary

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.
