What are the benefits of harmonic drives?
With operating principles and construction that maximize output torque and minimize size and weight, Harmonic Drive® gears offer advantages such as high reduction ratios in a single stage, zero backlash, and high precision that cannot be equaled by conventional gear trains.
Can you Backdrive a harmonic drive?
A high ratio harmonic drive is non-backdrivable because its output shaft cannot be turned by applying a torque on it.
What are the main components of a harmonic drive gear?
This special type of gear has a unique construction that comprises only three essential components: the wave generator, the flex spline and the circular spline. It enables large transmission ratios from high down to low rotational speeds.
How do harmonic drives work and what is the benefit of this system?
Harmonic Drive gears are noted for their ability to deliver precision motion control with very low or even zero backlash and vibration, providing high reduction ratios through concentric shafts in a lightweight yet robust assembly.
Can you run a gear reducer backwards?
Generally yes, if you use the original output shaft as the new input shaft then you would be achieving the opposite (i.e. converting high-torque input to high-speed output).
How does a harmonic drive work?
Harmonic Drive developed a unique gear tooth profile that optimizes the tooth engagement. This tooth profile (the “S tooth”) 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.
Where are harmonic drives used?
Harmonic Drives have been employed in a variety of applications that range from such low-cost consumer applications as vending machines and rotating home-television antennas to sophisticated systems for military and aerospace use.
How does a cycloidal gearbox work?
The motion of the planet gears drives the carrier and transmits the power to the output shaft. In the same way, the motion of the cycloidal discs drives a pin disc, which in turn transmits the power to the output shaft….Cycloidal drive vs. planetary gear.
| Planetary gear | Cycloidal drive | |

Who invented harmonic drive?
C. Walton Musser
The mechanism was the brainchild of the genius American inventor C. Walton Musser. Mr. Musser was a brilliant inventor who was awarded more than 200 patents, in a wide range of fields going even beyond his specialty in mechanical engineering to include also physics, chemistry, and biology.
What are speed increasers?
Rj Link Speed Increasers are manufactured in numerous sizes for a variety of products and markets. These custom built gearboxes are designed and built to accommodate high RPM specific components. All are designed with tapered roller bearings and helical gears. Many incorporate customer specific shafts and connections.
