Gear quality standards developed and published by the American Gear Manufacturers Association (AGMA), have dominated gear manufacturing in the U.S. market since the 1960s. But in the 1990s, AGMA began working with the International Organization for Standardization (ISO) to update and harmonize gear quality standards, with several versions of both AGMA and ISO standards published […]

NORD adds new gear units with thermally optimized housings
NORD’s new MAXXDRIVE XT series features right-angle gear units with thermally optimized housings, output torques from 132,800 to 663,800 lb-in, ratios from 6.14 to 22.91:1, and 30 to 2,825 hp across seven sizes. The MAXXDRIVE portfolio offers parallel and right-angle industrial gear units with high output torques from 132,800 to 2,301,200 lb-in, ratios from 5.54 […]
Gearbox buyers’ guide from Ondrives
After many years of discussing gearboxes with engineers, we have developed a questionnaire we use to ensure that we have found all the necessary details of an application. We use this even if the engineer specifies our standard part number. The correct gearbox may have been chosen, but: 1.Are there any lower-cost alternatives to consider […]
What are different ways to express a gear ratio?
In motion control systems, gears are used to change the torque and speed delivered by a motor to a driven component. Depending on how the gears are arranged, they can either increase the delivered torque and decrease the output speed (the most common arrangement in motion control applications) or decrease the delivered torque and increase […]
What are multi-stage gearboxes and when are they used?
Gearboxes are commonly used in motion control applications to change the output speed and torque from a motor to a driven component. By using a smaller gear with fewer teeth (commonly referred to as a pinion) to drive a larger gear with a higher number of teeth, the torque delivered to the load is increased while […]
Gears and gearmotor trends — more customized designs
Gearing and mechanical power transmission, in its fundamentals, remains virtually unchanged. However, innovative variations are becoming increasingly common and include more custom gearing, compact designs, and better gearboxes and servo-gear sets. Manufacturers are offering designers more customized solutions via more in-house engineering resources, simplifying the design process. More custom solutions also means greater integration with […]
Miniature gearing and planetary gearing in haptic feedback
Planetary gearsets offer applications advantages over other gearsets, including multiple kinematic combinations, power density, big reductions from compact setups, and pure torsional reactions. Planetary gearboxes also boost overall design efficiency. Losses never exceed 3% per stage, so the sets transmit most energy for productive motion output. In applications driven by servo systems, gearboxes also reduce […]
New large, hollow-shaft gear units from Harmonic Drive
The new FBS-2UH gear unit series from Harmonic Drive features a large, hollow shaft with a compact outer diameter. The extra large hollow shaft is suitable for robots and machines requiring complex cabling to pass through the axis of rotation. The new gear unit design features Harmonic Drive’s “S” tooth profile for optimal tooth engagement […]
