Harmonic Drive Reducer Working Principle
As a reducer, the harmonic drive gear reducer is often in status as the wave generator drives, the circular spline is fixed, and the flex spline is output end.
When the harmonic wave generator is put inside of the flex spline, the flex spline is forced into an elliptical shape causing the flex spline teeth to engage with the tooth profile of the circular
spline along the major axis of the ellipse, with the teeth completely disengaged across the minor axis of the ellipse.
The rotation of the wave generator makes the flex spline deform continuously, the teeth change operating state in the process of engagement and disengagement, thus the power harmonic drive
transmission between wave generator and flex spline is realized.
Characteristics of Harmonic Gear Reducer
High accuracy
A good percentage of harmonic gear reducer's teeth are meshed at all times and are engaged at two zones 180 degrees apart. This means influences of tooth pitch errors and accumulated pitch errors
on rotational accuracy are neutralized, which assures high positional and rotational accuracy.
High speed reduction ratio
A harmonic gear reducer has high single-stage reduction ratios also known as harmonic drive gear ratio or harmonic drive ratio of 1/30-1/500. Three basic components along same axle without complex
structures can provide high reduction ratios.
High torque capacity
Each tooth subjected to a negligible amount of force yet provides a high torque capacity because of the way the teeth come into contact with each other and because a good percentage of the teeth in
the flex spline is engaged at all times.
Small-sized and light weight
While being less the size of conventional gearing mechanisms and less the weight, the strain wave reducer provides the same levels of torque and speed reduction ratios as its conventional
counterparts enabling machinery and equipment to be made smaller and lighter.
Superior efficiency and long life time
As a professional harmonic drive gearbox company and strain wave gear manufacturer in China, Laifual Drive produces harmonic drive reducers with superior harmonic drive efficiency and long service
time.
Quiet and minimal vibration operation
Laifual Drive's harmonic drive reducers also operate with quiet and minimal vibration.
Harmonic Drives Uses
Harmonic drive reducers (also known as strain wave gearbox/reducer) are increasingly widely used in aviation, aerospace, energy, navigation, shipbuilding, bionic machinery, commonly used ordnance,
machine tools, instruments, electronic equipment, mining and metallurgy, transportation, lifting machinery, petrochemical machinery, textile machinery, agricultural machinery and medical equipment
and other aspects, especially in the servo system with high dynamic performance, the superiority of harmonic gear drive transmission is better showed.
Cycloidal vs Harmonic Drives
Cycloidal reducer:
Cycloidal reducer is used for the three joints of the robot with large torque: leg, waist and elbow and for the industrial robot with large load where cycloidal reducer is used in one, two and
three axes. Compared with the harmonic gear drive, the key of the cycloidal reducer lies in the processing technology and assembly technology. Cycloidal reducer has higher fatigue strength, better
rigidity and longer life. Its motion accuracy will not be significantly reduced with the increase of usage time. The disadvantage is that it is heavy in weight and large in size.
Harmonic drives:
Harmonic drives are usually used for industrial robots with small loads or several axes at the end of large robots. Harmonic drive gearbox is a kind of harmonic drives, which includes harmonic
accelerator and harmonic gear reduction. The harmonic reducers mainly includes: rigid wheel, flexible wheel, bearing and wave generator, all of them are indispensable. The characteristics of
harmonic drive gearbox used in small robots are small size, light weight, large carrying capacity, high motion accuracy, and large single-stage transmission ratio.
Both cycloidal reducer and harmonic reducers are internal gearing with small tooth number difference. The difference is that a key gear in the harmonic is flexible. The key gear needs to be
repeatedly deformed with high speed, so it is relatively fragile, and its bearing capacity and life are limited. Cycloidal reducer usually uses cycloidal pinwheels. Harmonics used to use involute
tooth shape. Now some harmonic gearbox manufacturers use double arc tooth shape, which is much more advanced than involute tooth shape.
Thanks to years of R&D experience, the precision harmonic drives produced by our company have made major breakthroughs in various special properties. Our harmonic drive gearboxs have the
characteristics of low temperature rise, low starting torque, high reliability, high precision, high torque, high rigidity, light weight, long life, large speed ratio and small volume. They can be
used in batches in industrial robots, service robots, medical equipment, high-precision automation equipment and other fields. What's more, we also provide custom services, so feel free to contact
us if you have any need.
Composition of Harmonic Gear Reducer
Harmonic gear reducer has three basic components：a wave generator,a flexspline and a circular spline.
01Wave Generator
Harmonic gear reducer is made up of a ball bearing and an elliptical cam. The harmonic drive wave generator is usually attached to the input end, the inner ring of the harmonic drive bearing is
fixed around the cam causing the outer ring of the bearing deforms to an elliptical shape.
02Flex Spline
It is an elastic thin-walled component with gear teeth on the outer surface. Harmonic gear reducer is usually fitted to the output end.
03Circular Spline
It is a rigid steel ring with internal teeth. Harmonic gear reducer usually has two more teeth than the flex spline, and generally mounted onto a housing.
