Self-adapting damping device of transmission system

Abstract

The invention discloses a drive system self-adaptive damping device, comprising a power output shaft I and a power output shaft II which are coaxially arranged, a lever I and a lever II, a drive gearI and a drive gear II, a driven gear I and a driven gear II which are respectively meshed with the drive gear I and the drive gear II, and the drive ratio of the two gear pairs are the same, wherein,the power output shaft I and the power output shaft II are respectively arranged on two sides of a fulcrum of the lever I and a fulcrum of the lever II; the lever I and the lever II are respectively arranged on two sides radially opposite to the power output shaft I and the power output shaft II, and are fixedly matched with the power output shaft I and the power output shaft II in circumferentialdirection; the driven gear I is fixedly matched with the fulcrum of the lever I and the fulcrum of the lever II in the circumferential direction, and the driven gear II is fixedly matched with the power output shaft II in the circumferential direction. The drive system self-adaptive damping device has a strong self-adaptability to superimposed interference and quick response time, can reduce thereturn difference to a lower value, has long service life and convenient maintenance, and is always in a self-locking state. The drive system can not generate a reverse motion with simple structure and good manufacturability.

Description

technical field [0001] The invention relates to a mechanical transmission device, which is an adaptive damping device of a transmission system. Background technique [0002] Gear transmission is used to transmit motion and power between two shafts. Compared with other mechanical transmissions, gears have the advantages of compact structure, smooth operation, and low noise, so they are widely used in various machines and instruments. [0003] With the development of production technology and the demand for high-quality products, especially the development needs of precision heavy-duty transmissions such as aerospace, aviation, and military industries, higher requirements are placed on transmission accuracy and backlash control. [0004] The main problem in the transmission system is the meshing gap of the gear pair and the movement hysteresis. Damping devices are widely used, and most of the damping devices use gear transmission. In the prior art, there are many structures to...

Problems solved by technology

However, these technologies are still complicated in structure and assembly in terms of structural design or manufacturing process, and the cost is high. They are only suitable for small power systems and cannot completely solve the problem of backlash in gear transmission.

The main thing is that the interference outside the system cannot be overcome. When an external additional torque is applied to the output of the system, it will destroy the motion mode and motion accuracy of the system.
