Creation Of A Computational 2d Model Of Harmonic Gearbox

A harmonic drive gear is, in fact, a differential gear with front-wheel drive in which the gear is achieved by elastic deformation of the flexible spline. The spline harmonic drive gear is typical for its unique structure called "strain cam wave generator". The principle of functioning of these gear systems is based on the mechanism of rotationally elliptical deformation of the flexible spline using the elliptical wave generator and subsequent tooth generating. When dealing with these types of gear systems, we come across the term "backslash", which is a surplus clearance between the generating teeth. When designing a harmonic drive gear for robots, it is important that the backslash is as low as possible. This chapter focuses on the preparation of the finite element model of a harmonic drive gear. It provides readers with a complete overview of the functions of these special, really precise and stiff gear systems and their properties. Harmonic drive gearing systems have been widely used in the area of precise control. Precise reduction and positioning have been mainly used in robotics. Its high rate of precision and weight has been used in the aviation industry. The system is also used in the engineering industry for transmission of high torque, conveyor and turbine drives and in many other machine applications.
