Solid lubrication precision wave filtering driving device

Abstract

It relates to a solid lubrication fine wave filter drive device. It integrates the design of the decelerator component, output drive mechanism and servo generator to ensure the precision drive on structural basis. The input dual gear can cause offset rotation through the offset cam, generating two teeth missing differential drive by the teething part of the fixed gear and the output gear. It has arc slot rolling movement channel and installed with bearing on the offset cam. The drive sub teething surface is coated with energy absorbing, noise reducing, wear resistant solid lubricant film with proper resilience to get rid of the stiffness of the structure. It has high precision, reliability, durability, big toque, low energy consumption, light weight.

Problems solved by technology

[0002] For a long time, the drive motor and the reduction mechanism have been designed separately in robotics, automation, vehicles, aviation, aerospace, electronics industry, military industry and other mechanical equipment, so it is inevitable to consider the connection design between them and the alignment of the shaft system error, and the transmission mechanism is worn, and the mechanism is prone to jamming

For example, planetary reducers, cycloid reducers and RV reducers have complex structures, and it is difficult to achieve a large transmission ratio. When the mechanism is jammed, the dynamic performance is poor and the mechanical efficiency is reduced. The additional dynamic load is large, especially the transmission is large. High power, vibration and noise

Under the long-term alternating load, the flexible spline of harmonic drive is prone to fatigue wear failure, mechanism jamming, poor workmanship, high manufacturing and processing requirements, and inconvenient maintenance

This directly leads to problems such as poor transmission accuracy, comprehensive performance and reliability caused by the mechanical transmission system, shortened service life of equipment, and problems such as large friction, wear, vibration, noise, and reactive power consumption in mechanical equipment.
