Pittman Motors has significantly expanded its gearbox offerings with the introduction of PLG24, PLG42K, PLG42S, PLG52, and PLG63 planetary gearboxes. These gearboxes are now available with Pittman brush and brushless DC motors and complement Pittman's existing spur and planetary gearbox lines.
The new products add 35 standard motor-gearbox family combinations to the Pittman offerings. The PLG planetary gearboxes deliver high torque loads with excellent efficiency and are small, durable, and quiet. These features make them suitable for a variety of OEM precision motion-control applications, including pan/tilt functions, indexing, pumping, conveying, and traction applications.
The gearboxes are particularly useful in designs for medical and laboratory instrumentation, industrial equipment, material handling, and transportation. The new PLG gearboxes come in diameters from 24 to 63 mm and output torques to 100 Nm (74 lb ft).
Reduction ratios range from 4:1 to 710:1 with more than ten standard ratios available in each size. Construction features vary, but typical versions include gears and ball bearings made of steel or engineered polymer.
OEMs can specify custom output-shaft features, lubrication, and reinforced output-shaft assemblies for differentiated solutions tailored to specific application requirements.
