Harmonic Gearbox Drive Servo Drive Component Sets for Robot Motion Control

The harmonic drive based on metal elasticity consists of only three basic components (wave generator. flexible wheel and rigid wheel),(because of the different shapes,some of them are composed of four basic components,but the driving principleremains unchanged)
Wave aenerator:elliptical cam with a thin ball bearina embedded in the periphery. The inner wheel of the
bearing is fixed on the cam. and the outer ship realizes the elastic deformation through the ball. Usually
mounted on the input shaft
Flexible wheel:thin-walled metal elastomer parts. The outer part of the opening is provided with a gear and is usually mounted on the output shaft.
Rigid wheel:rigid annular parts.The inside is engraved with gears,the number of gears is two more than flexible wheel's usuallv fixed on the shell

Since the flexible wheel will undergo elastic deformation repeatedly, the transmission torque of harmonic drive is determined based on the fatigue strength of the flexible gear bottom.
The values of rated torque and allowable peak torque at start and stop are all within the fatigue limit of flexible gear bottom.
The value of instantaneous allowable maximum torque(impact torque)is the limit value within the fatigue limit of the soft gear bottom. and the fatique failure may occur when the instantaneous allowable maximum torque is exceeded frequently.Therefore,in order to avoid fatigue failure,the number of impact torque should be limited

FAQ

Q: What should I provide when I choose gearbox/speed reducer?

A: The best way is to provide the motor drawing with parameter. Our engineer will check and recommend the most suitable gearbox model for your refer.

Or you can also provide below specification as well:

1) Type, model and torque.

2) Ratio or output speed

3) Working condition and connection method

4) Quality and installed machine name

5) Input mode and input speed

6) Motor brand model or flange and motor shaft size
