Planetary gearboxes provide winch solution
Working very closely with winch manufacturers, GSM Power Transmissions has supplied compact planetary gearboxes which fit inside a winch drum and provides the necessary torque and speed to deliver the line speed required at the designated line pull.
The planetary gearbox offers winch manufacturers a great deal of flexibility within their design. Because of the modular design ratios from 3:1 to 15,000:1 are possible. The compactness is a feature due to the torque being transmitted from the sun-pinion to the planet carrier via three and sometimes up to five points of contact with the planet gears - all encompassed within a planet ring.
Each planet gear is mounted on needle roller bearings which make for an extremely efficient gearbox. Typically planetary gearboxes can be 98% efficient per stage of reduction and on a three-stage reduction the ratio achieved can be approximately 350:1 and still 94% efficient.
The planetary gearbox also employs the use of taper roller bearings at the low speed output shaft which have a capacity to cater for high radial loads associated with lifting loads by winches.
GSM offers a wide range of products to the UK market, including bevel helical and parallel helical gearboxes with ratios from 1.11:1 to 801:1 and torques to 692.000Nm.
