Regular applications for these reducers include precision rotary axis drives, traveling gantries & columns, materials handling axis drives and digital line shafting. Industries served include Material Managing, Automation, Aerospace, Machine Tool and Robotics.
The servo gearboxes PT complete the complete selection of our servo gearboxes that contain high-end planetary gearboxes, right angle gearboxes, hypoid gearboxes, cycloid gearboxes in addition to various combinations thereof. All common servo motors could be easily set up with all sizes of our gearboxes. Our PT servo planetary gearboxes assure high stiffness and reliable transmission through their particular design. All band gears, planet gears and sunlight pinions are case – hardened and ground. This gives an outstanding transmission quality and allows for precise positioning tasks.

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

Some planetary-geared servo-motors offer additional options. For instance, oil-stream lubrication and cooling lets planetary gearbox for servo motor devices operate continually at up to three times the nominal torque and power rating. Oil-cooling also will keep the actuator great in high-temperature environments. Additional options include explosionproof designs, alternative materials and coatings, custom shafts, nonstandard motor voltages such as 24 or 48 Vdc, special feedback gadgets, and special electrical connectors to operate with most amplifiers.
This standard selection of Precision Planetary Reducers are perfect for use in applications that demand high performance, precise positioning and repeatability. They were specifically developed for use with state-of-the-art servo motor technology, providing tight integration of the engine to the unit. Design features include installation any servo motors (IEC, NEMA, or personalized motors), standard low backlash, high torsional stiffness, 95 to 97% efficiency and quiet running.

Fewer parts also offer small packaging in comparison to bolt-on reducers. Bolt-on gear-heads frequently use right-angle gears to reduce the length a reducer extends beyond a machine. Right-position gears, however, require yet another group of bevel gears to help make the turn. These gears increase the solution’s size, cost, complexity, and total backlash since another system is placed between your load and the engine. Usage of beveled gears defeats the benefit of a planetary gearhead completely.
