Standard applications for these reducers servo worm reducer include precision rotary axis drives, traveling gantries & columns, materials handling axis drives and electronic line shafting. Industries served include Material Handling, Automation, Aerospace, Machine Tool and Robotics.
The servo gearboxes PT complete the whole selection of our servo gearboxes that contain high-end planetary gearboxes, right angle gearboxes, hypoid gearboxes, cycloid gearboxes and also various combinations thereof. All common servo motors can be easily set up with all sizes of our gearboxes. Our PT servo planetary gearboxes assure high stiffness and reliable transmission through their unique design. All band gears, planet gears and sun pinions are case – hardened and ground. This gives an outstanding transmission quality and permits 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 solid shaft or ISO 9409-1 flange, for mounting to rotary or indexing tables, pinion gears, pulleys or other drive elements with no 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 these reducers are also available.
Some planetary-geared servo-motors offer additional options. For example, oil-circulation lubrication and cooling lets systems operate continuously at up to three times the nominal torque and power rating. Oil-cooling also maintains the actuator cool in high-temperature environments. Additional options include explosionproof designs, alternative components and coatings, custom shafts, nonstandard electric motor voltages such as for example 24 or 48 Vdc, special feedback gadgets, and special 
electric connectors to operate with most amplifiers.
This standard range of Precision Planetary Reducers are ideal for use in applications that demand powerful, precise positioning and repeatability. These were specifically developed for use with state-of-the-art servo motor technology, providing limited integration of the electric motor to the unit. Style features include installation any servo motors (IEC, NEMA, or customized motors), standard low backlash, high torsional stiffness, 95 to 97% efficiency and tranquil running.
Fewer components also offer small packaging compared to bolt-on reducers. Bolt-on gear-heads regularly 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 make the switch. These gears raise the solution’s size, cost, complexity, and total backlash since another system is placed between the load and the motor. Use of beveled gears defeats the advantage of a planetary gearhead completely.
