Standard applications for these reducers include precision rotary axis drives, traveling gantries & columns, materials handling axis drives and digital line shafting. Industries served include Material Handling, Automation, Aerospace, Machine Tool and Robotics.
The servo gearboxes PT complete the whole range of our servo gearboxes that contain high-end planetary gearboxes, right angle gearboxes, hypoid gearboxes, cycloid gearboxes along with various combinations thereof. All common servo motors could be easily installed with all sizes of our gearboxes. Our PT servo planetary gearboxes guarantee high stiffness and reliable transmission through their unique design. All band gears, world gears and sunlight pinions are case – hardened and ground. This provides a superb transmission quality and permits precise positioning tasks.

They are available in nine sizes with reduction ratios from 3:1 to 600:1 and result torque capacities up to 16,227 lb.ft. The output can be provided with a solid shaft or ISO 9409-1 flange, for installation to rotary or indexing tables, pinion gears, pulleys or other drive elements without the need for a coupling. For high precision applications, backlash amounts right down to 1 arc-minute can be found. Right-angle and insight shaft versions of the reducers are also offered.

Some planetary-geared servo-motors offer additional options. For example, oil-movement lubrication and cooling lets systems operate consistently at up to three times the nominal torque and power ranking. Oil-cooling also maintains the actuator cool in high-temperature environments. Various other options include explosionproof designs, alternative components and coatings, customized shafts, nonstandard motor voltages such as 24 or 48 Vdc, special feedback devices, and special electric connectors to use with most amplifiers.
This standard range of Precision Planetary Reducers are perfect for use in applications that demand powerful, precise positioning and repeatability. They were specifically developed for use with state-of-the-art servo engine technology, providing tight integration of the electric motor to the unit. Style features include mounting any servo motors (IEC, NEMA, or personalized motors), standard low backlash, high torsional stiffness, 95 to 97% efficiency and calm running.

Fewer components also offer small packaging compared to bolt-on reducers. Bolt-on gear-heads regularly use right-position gears to planetary gearbox for servo motor reduce the space a reducer extends beyond a machine. Right-angle gears, however, require yet another set of bevel gears to help make the turn. These gears increase the solution’s size, cost, complexity, and total backlash since another mechanism is placed between your load and the electric motor. Use of beveled gears defeats the advantage of a planetary gearhead altogether.
