Product Description

Harmonic drive gearbox T-CSG-2A-G High Precision Cup type Harmonic drive Gear Speed Reducer

The principle of gear transmission

The harmonic gear transmission is invented by the American inventor C.W.Musser in 1955. It is a new

type of transmission mode which usesstrain wave gearto move into motion or power by

elastic deformation. It breaks through the mode of mechanical transmission with rigid component

mechanism and uses a flexible component to realize mechanical transmission. Thus, a series of special

functions which are difficult to achieve by other transmission are obtained. Because the deformation

process of the intermediate flexible member is basically a symmetrical harmonic, it is named.

The composition of the gear transmission

Rigid spline:

It is a part of rigid round ring carrying internal tooth circle, in general, it holds 2 more gear teeth than those of flexspline. The rigid spline is usually fixed on the body of reducer machine.

Flexibinele spline:

It is a part of thin-walled elastomer carrying external tooth circle,which is generally equipped at output end of reducer.

Wave generator:

It is composed of flexible bearing and oval cam. Wave generator is generally equipped at the input end of reducer with internal circle of flexible bearing fixed on the cam and elastic deformation of external circle to oval shape realized by means of roll balls.

The principle of gear transmission deceleration

When harmonic wave is used as reducer, wave generator is active, rigid spline is fixed, and flexspline takes output form.

When wave generator is loaded into internal circle of flexspline, flexspline is deformed to oval shape due to elasticity, then flexspline teeth at long axis place are inserted into rigid spline trough, thus complete meshing status is realized. At this time, two wheels of gear teeth at short axis place do not contact completely, in other words, at the disconnected position. In the process from meshing to disconnection, the harmonic gear drive is at the status of meshing out or meshing in.

When wave generator rotates continuously, flexspline is deformed unceasingly, two wheels of gear teeth will change their own working status from meshing in, meshing, meshing out to disconnection, thus the so-called wrong tooth movement happens, finally movement transmission from active wave generator to flexspline is achieved
