Product Description
Product Description
The HMHG-II series harmonic reducer applies a compact structure with through-hole where the input shaft is connected to the inner hole of the wave generator. It can work with the flexspline fixed as input end, while circular spline turns as output end, or vice versa. It’s currently available in production specifications ranging from 14 to 40, this series finds its main applications in 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.

Power Transmission in Farming Equipment with Agricultural Gearboxes
Agricultural gearboxes play a vital role in facilitating power transmission within various types of farming equipment. These gearboxes are integral components that enable the transfer of rotational power from a tractor’s engine to different agricultural implements and machinery. Here’s how agricultural gearboxes contribute to power transmission:
- Speed Reduction: In many farming operations, the engine of a tractor or other power source operates at a higher speed than is suitable for the optimal functioning of agricultural implements. Agricultural gearboxes provide speed reduction by using a combination of gears with different numbers of teeth. This reduction in speed allows the machinery to operate at the required speed for efficient tasks like tilling, planting, or harvesting.
- Power Multiplication: Some agricultural tasks require a significant amount of torque to operate effectively. Gearboxes can multiply the input torque from the engine to generate higher torque at the output shaft. This is crucial for tasks such as plowing, where substantial force is needed to break up the soil.
- Directional Change: Agricultural gearboxes also allow for changes in the direction of power transmission. For instance, a tractor’s power take-off (PTO) shaft may need to transmit power at a right angle to the tractor’s engine. Gearboxes with bevel gears or other arrangements enable this change in direction, ensuring that power is properly directed to the implement.
- Power Distribution: In certain cases, power needs to be distributed to multiple components or implements. Agricultural gearboxes with multiple output shafts can distribute power to different tasks simultaneously, optimizing efficiency and productivity.
- Attachment Operation: Many agricultural implements, such as plows, seed drills, and rotary mowers, require consistent and controlled power to function effectively. Gearboxes provide the necessary power and control to these attachments, ensuring uniform operation and accurate results.
By facilitating speed reduction, power multiplication, directional changes, power distribution, and attachment operation, agricultural gearboxes contribute significantly to the overall efficiency and productivity of farming equipment. They allow farmers to adapt their machinery to various tasks, optimize power usage, and achieve better results in different agricultural operations.
