Product Description
The HMHG-IV series harmonic reducer features a standard structure and the wave generator comes with an input shaft, The reducer is designed with supporting bearings and a fully sealed structure, making it easy to install. It is very suitable for situations where umbrella gears or synchronous belts need to be installed at the input end for rotation. Currently available in production specifications ranging from 14 to 40, this series is primarily used in high precision fields such as aerospace, robotics, semiconductors, power inspection, and automation equipment.
Principle of harmonic gear transmission
The harmonic gear drive was invented by the American inventor C.W.Musser in 1955. It is a new transmission mode using the elastic deformation of flexible working components to carry out movement or power transmission. It breaks through the mode of mechanical transmission using rigid components and uses a flexible component to achieve mechanical transmission. Thus, a series of special functions that are difficult to achieve with other drives are obtained. Because the deformation process of the intermediate flexible component is basically a symmetrical harmonic, it is named. In addition to the Soviet Union called this transmission waveform drive or flexible wheel drive, the United States, Britain, Germany, Japan and other countries are called “harmonic drive”.
Harmonic deceleration principle
The deceleration principle of harmonic gear transmission refers to the use of the relative motion of the flexwheel, rigid wheel and wave generator, mainly the controllable elastic deformation of the flexwheel to achieve motion and power transmission. The elliptic CAM in the wave generator rotates in the flexwheel so that the flexwheel deforms. When the flexwheel teeth and rigid wheel teeth at both ends of the long axis of the elliptic CAM of the wave generator are engaged, the flexwheel teeth at both ends of the short axis are detached from the rigid wheel teeth. The teeth between the long axis and the short axis of the wave generator are in a semi-meshing state that gradually enters the snapping along different sections of the perimeter of the flexwheel and the rigid wheel, which is called the snapping; In a semi-meshing state that gradually withdraws from engagement, it is called snapping out. When the wave generator continuously rotates, the flexwheel constantly deforms, so that the 2 wheel teeth in the biting, meshing, biting out and disengaging 4 kinds of motion constantly change their original working state, resulting in the wrong tooth movement, to achieve the active wave generator to the flexwheel movement transmission.
