Double Worm Gearing
The exclusive usage of the involute helicoid thread form on the worm and gear provides for high efficiencies and lengthy service lifestyle. The hardened, ground and polished alloy steel worm develops a simple, work hardened surface area on the bronze equipment. For this reason, the worm gears use in and improve with prolonged service while additional gears are deteriorating.

The worm shafts are made of high quality case hardening steel, accurately generated, ground and super finished. The worm tires include phosphor bronze centrifugally cast rims of substantial sections welded to rigid centers. Considerable versatility of shaft layout is certainly permissible with all sorts of Double Reduction units. The dimension drawing for each series shows the different shaft handing arrangements and the correct reference should be quoted when buying.
Our standard 700 Series – the heart of Ever-Power speed reducer product line – has been serving industry reliably for over 40 years. Its verified modular design has set the industry standard for overall performance and is the most imitated product in today’s worm gear swiftness reducer double reduction worm gearbox marketplace. But why settle for a knock-off when you can have the initial – from Ever-Power.

DOUBLE REDUCTION GEAR
Ever-Power Double Reduction Worm Gear Devices are constructed using two solitary reduction worm gear units. The primary worm gear device is specially made to mount integrally on a standard single worm gear device which forms the secondary stage. The complete gear unit becomes small and rigid in arrangement for slow shifting machinery. A wide range of ratio from 75:1 to 4900:1 is available. These equipment units are particularly suitable for high torque slow-velocity drives. Worm gearing conforms to BS-721.
