Harmonic drive developed a unique gear tooth profile that optimizes the tooth engagement. This tooth profile enables up to 30% of the total number of teeth to be engaged simultaneously. Additionally, the large tooth root radius increases the tooth strength compared with an involute tooth. Harmonic Drives have been employed in a variety of applications such as military and aerospace use. Harmonic gearbox is also known as Strain Wave gearbox. Harmonic gearing is a type of mechanical gear system that uses a flexible spline with external teeth, which is deformed by a rotating elliptical plug to engage with the internal gear teeth of an outer spline.
Harmonic gearbox came with its attractive features like compactness and light weight, High gear ratio. It comes with reconfigurable ratios within a standard housing. Harmonic reducer has a high torque capability with coaxial input and output shafts. The one of the main feature of harmonic drive reducer is, it comes with no backlash. It can provide reduction but can be also used to increase rotational speed.
Harmonic drive components
The mechanism of Strain wave drive consists of a toothed mechanism comes with 3 components i.e. Circular spine, Flex spine, Wave Generator.
The circular spline is a solid steel ring with internal teeth. The flex spline is a flexible steel cylinder with external teeth. The drive is executed by the wave generator, It’s a thin-race ball bearing that is fitted onto an elliptical plug. The elliptical shape of the wave generator helps the teeth of the flexspline to engage circular spline at two regions at opposite ends of the major axis of the ellipse.
Applications of Harmonic Gearbox
Harmonic gearbox can be used in any gear reduction application where small size, low weight, zero backlash, very high precision and high reliability are required. Examples include aerospace applications, robotics, electric vehicles, medical x-ray and stereotactic machines, milling and lathe machines, flexo-printing machines, semiconductor equipment, optical measuring machines, woodworking machines and camera head pans and tilt axes. The Harmonic gear box is very useful when the axis moments are required for example in Robot arm.
