Common applications for these reducers include precision rotary axis drives, traveling gantries & columns, materials handling axis drives and digital line shafting. Industries offered include Material Managing, Automation, Aerospace, Machine Tool and Robotics.
The servo gearboxes PT complete the complete selection of our servo gearboxes that consist of planetary gearbox for servo motor high-end planetary gearboxes, right angle gearboxes, hypoid gearboxes, cycloid gearboxes along with various combinations thereof. All common servo motors can be easily set up with all sizes of our gearboxes. Our PT servo planetary gearboxes ensure high stiffness and reliable transmission through their particular design. All band gears, planet gears and sun pinions are case – hardened and ground. This gives a superb transmission quality and allows for 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 mounting to rotary or indexing tables, pinion gears, pulleys or other drive components without the need for a coupling. For high precision applications, backlash amounts right down to 1 arc-minute are available. Right-angle and input shaft versions of the reducers are also obtainable.
Some planetary-geared servo-motors offer additional options. For example, oil-flow lubrication and cooling lets models operate continually at up to 3 x the nominal torque and power ranking. Oil-cooling also maintains the actuator cool in high-temperature environments. Other options include explosionproof designs, alternative materials and coatings, customized shafts, nonstandard electric motor voltages such as for example 24 or 48 Vdc, special feedback products, and special electrical connectors to use with most amplifiers.
This standard range 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 limited integration of the engine to the unit. Design features include mounting any servo motors (IEC, NEMA, or customized motors), standard low backlash, high torsional stiffness, 95 to 97% efficiency and quiet running.
Fewer components also offer compact packaging compared to bolt-on reducers. Bolt-on gear-heads often use right-angle gears to reduce the space a reducer extends beyond a machine. Right-position gears, however, require an additional set of bevel gears to make the switch. These gears raise the solution’s size, price, complexity, and total backlash since another system is placed between your load and the engine. Use of beveled gears defeats the benefit of a planetary gearhead altogether.
