Ondrives.US Corporation, formerly Rino Mechanical In-Line Gearboxes and Speed Reducers Planetary Servo Gearboxes

Ondrives.US offers standard and customized in-line gearboxes to meet the needs of nearly any motion or power transfer application. Our inline gearboxes are engineered for low backlash performance. They are precision built to provide reliable service in even the most demanding operations. Gearboxes are known by many different names, including gear drives, reducers, gear reducers, speed reducers, and gearmotors. All terms can be used more or less interchangeably. Spur In-Line Gearboxes Ondrives.US offers a full line of compact, lightweight spur gear in-line planetary gearboxes. These gearboxes can be direct mounted to motors or used with shaft coupling. Ratios from 2:1 to 625:1 are available, with torque values ranging from 0.13Nm to 90Nm. Input speed: up to 4,000 RPM Precision machined aluminum housing Dual ball bearings on all shafts Encoder Low Backlash In-Line Gearboxes These compact, lightweight, low backlash gear drives are designed specifically for encoder applications. They have a very low moment of inertia at the shaft input, and are rated for input speeds up to 3,000 RPM. Gear ratios from 4.96:1 to 3600:1 are available, in two frame sizes. Synchro cleats for our encoder gearboxes are available from stock. Output torque: 1 oz.-inch Backlash: 15 arc-minutes (at any ratio) Ratios from 4.96:1 to 3600:1 Input speeds up to 3,000 RPM Diameter: 1-1/16” or 1-3/4” Black anodized aluminum housing 303 stainless steel gears and shafts Ball bearings Low Backlash Inline Taper Gearboxes Our taper gearmotors are inline planetary gear reduction boxes with backlash equal to or better than 8 arc/minute. These inline gearboxes are designed for applications where space is limited, and are available either as a shaft input or mounted to a 24V DC motor. Low backlash: ≤8 arc/min. at input Compact design Shaft input or with mounted motor Ratios from 2:1 to 16:1 Output torque values from 1.14Nm to 12.7Nm Epicyclic (Planetary) Servo Gearboxes The Ondrives.US line of internal epicyclic servo reducers are extremely rugged and compact. These planetary gearboxes have fully-machined housings (aluminum or steel), and are outfitted with ball bearings throughout. Our inline planetary gear reducers offer flexible motor mounting options and can deliver output torques up to 380 Nm. Ratios from 3:1 to 36:1 are available. Low backlash: ≤30 arc/min. at input Input speeds as high as 3,000 RPM Precision machined aluminum housings Dual ball bearings on all shafts Available in ratios from 3:1 to 36:1 Output torques as high as 380 Nm Speed Increaser Gearboxes Our low ratio Encoder gearboxes and inline taper gearboxes can also be used as gear speed increasers, if needed.
