Precise drive differential-type isolating device in reverse motion

Abstract

The invention discloses a precise drive differential-type isolating device in reverse motion. A level I and a level II are arranged in a power input sheath along the axial direction. A drive pin penetrates through the power input sheath, the level I and the level II along radial direction. The drive pin is used as a fulcrum of the level I and the level II and leads the level I and the level II tobe fixedly matched with the power input sheath in circumferential direction. The dynamic points of the level I and the level II are arranged on and fixedly matched with the radial opposite sides of adynamic output shaft I in circumferential direction. The resistance points of the level I and the level II are arranged on and fixedly matched with the radial opposite sides of a dynamic output shaftII in circumferential direction. A balance shaft are matched with the dynamic output shaft I and the dynamic output shaft II through a gear pair I and a gear pair II which has the same transmission ratio. The invention can isolate reverse disturbance motion from positive function motion, and can realize passive autobalance in the balance shaft of another system, eliminates the disturbance to positive function motion, and has strong adaptability to additional disturbance, and also has fast response time. The system is in a self-locking condition all the time; the backlash can be reduced; the service life is long; the maintenance is simple and convenient; the structure is simple; and the manufacturability is good.

Description

technical field [0001] The invention relates to a high-precision mechanical transmission device, which is a precision transmission differential reverse motion isolation device. 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] In the transmission process of the transmission system, there is an additional torque interference from outside the system. The existing structure cannot overcome the interference outside the system. When an external additional torque is applied to the output end of the system, it will destroy the motion mode of the system. and movement precision. In the field of high-tech technology, the precision transmission system requires strict motion mode and motion accuracy, and requires a large load-carrying cap...

[0003] In the transmission process of the transmission system, there is an additional torque interference from outside the system. The existing structure cannot overcome the interference outside the system. When an external additional torque is applied to the output end of the system, it will destroy the motion mode of the system. and motion precision

In the field of high-tech technology, the precision transmission system requires strict motion mode and motion accuracy, and requires a large load-carrying capacity, and the equipment where the transmission system is located is in a relatively harsh environment, and the workload fluctuates greatly, forming an additional interference Torque is applied in reverse to the transmission system, thus destroying the motion mode and motion accuracy of the transmission system, and failing to achieve the preset function of the equipment
