Worm Gear Reducers, Aluminium Housing

Worm gear reducers with cost iron housing were in existence for almost half a century. The recent trend is to use aluminium alloy housing in small worm gear reducers. Power Pack aluminium housings are aesthetically very attractive and the housing construction is such that it gets rigidity and strength, whereby they have an edge over the cast iron housing. There is no oil vent, which allows the gear reducer to be mounted in any position on equipment without concerns for vent leaks. The gearbox is supplied with factory filled synthetic lubricant, which avoids frequent oil change. In addition, the housing has a heat sink design, which is said to provide greater surface area for higher thermal capacity. The worm gear reducers come in sizes as 44, 50, 63 centre distance (mm); ratios from 7.5:1 to 60:1 are available. The gears totally conform to IS 33734/1966 for worm gearing. Advantages: lightweight, rigidity, no oil leakage, ease of assembly disassembly; and hollow input shaft with motor flange and hollow output shaft as standard. These units are available in many sizes and input kilowatt or output torque. The ratings are based on unity factor of 12 hours continuous running under uniform load subject to recommended lubrication and temperature limitation of 90?C.
