Description
Planetary Gearbox
PG planetary gear units are divided into 21 basic groups depending on the different torques that are to be transmitted to the output shaft, which can vary from 0,05 to 1.280 kNm. In fact, the product modular construction permits the coupling of bevel gears, worm gears, hydraulic brakes and a variety of input shafts to the planetary units, as well as providing for a wide choice of coupling flanges for hydraulic or electric motors. Another advantage offered by the modular construction technique of the planetary gear units is the possibility to mount a series of stages of different sizes in order to obtain a vast range of reduction ratios. The product range provides reduction ratios from 3:1 to 7:1 on a single stage unit up to 10.000:1 and more on a 5 stage unit. The wide selection of output shafts and flanges simplifies the reduction unit mounting operation on industrial machinery or plants.
Features:
– Planetary Gearbox
– Inline & Bevel stages
– Torque range: from 0,05 to 1.280 kNm
– Coupling flanges for hydraulic or electric motors
New hydraulic motors have a higher-rated operating pressure and features a larger and more durable motor-shaft seal.
New integral motor and planetary gearbox housing brings the planetary gear set closer to the motor, increasing efficiency and decreasing stress.
Gearbox has an updated input shaft with a more sturdy design.
Maximum torque rating for PA30B increased from 4,166 to 4,500 ft.-lb. and improved gear reduction. The number of planet gears in the PA30B gearbox increased from three to five.
PA40 bit sizes include 4-36-in. HD, 9-24-in. HD difficult ground, 18-36 in, tree and shrub, and 9- or 12-in. rock to match the application.
