Normal 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 selection of our servo gearboxes that contain high-end servo worm reducer 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 dependable transmission through their particular design. All band gears, world gears and sunlight pinions are case – hardened and ground. This provides an outstanding transmission quality and permits precise positioning tasks.
They are available in nine sizes with decrease ratios from 3:1 to 600:1 and output torque capacities up to 16,227 lb.ft. The output could 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 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-flow lubrication and cooling lets units operate continually at up to 3 x the nominal torque and power rating. Oil-cooling also will keep the actuator awesome in high-temperature environments. Various other options include explosionproof styles, alternative materials and coatings, custom shafts, nonstandard engine voltages such as for example 24 
or 48 Vdc, special feedback gadgets, and special electric connectors to operate with most amplifiers.
This standard selection of Precision Planetary Reducers are ideal for use in applications that demand high performance, precise positioning and repeatability. These were specifically developed for make use of with state-of-the-art servo engine technology, providing tight integration of the motor to the unit. Design features include mounting any servo motors (IEC, NEMA, or customized motors), regular low backlash, high torsional stiffness, 95 to 97% efficiency and noiseless running.
Fewer elements also offer compact packaging compared to bolt-on reducers. Bolt-on gear-heads regularly use right-angle gears to reduce the distance a reducer extends beyond a machine. Right-angle gears, however, require yet another group of bevel gears to make the switch. These gears increase the solution’s size, cost, complexity, and total backlash since another system is placed between your load and the electric motor. Use of beveled gears defeats the advantage of a planetary gearhead completely.
