Double Worm Gearing
The exclusive usage of the involute helicoid thread form on the worm and gear provides for high efficiencies and long service existence. The hardened, floor and polished alloy metal worm develops a smooth, work hardened surface on the bronze gear. For this reason, the worm gears put on in and improve with extented service while various other gears are deteriorating.

ouble Reduction Worm Gearbox
Ever-Power Double Reduction Worm Gearboxes are two stage worm reduction units.
A specially designed primary worm decrease device is integrally mounted on a standard single decrease Ever-Power worm gearbox which forms the second stage. The composite devices provide the most small and rigid arrangement for large reduction of speed necessary for sluggish shifting machinery. A wide range of ratios up to 4900:1 is offered.
Double Decrease Worm Gear Box Sizes Available with us are 40, 50, 60, 75, 85, 100, 125, 150, 175, 200, 250, 300, 350, 430.
Nominal Gear Ratios: 100:1, 150:1, 200:1,300:1, 400:1, 600:1, 750:1, 1000:1, 1200:1, 2000:1, 2800:1
Nominal ratios listed certainly are a typical selection of commonly utilized ratios from the overall range of Ever-Power Dual Reduction Worm Gear Box. Information on other ratios available on request.

The worm shafts are made from high quality case double reduction worm gearbox hardening steel, accurately generated, ground and super finished. The worm tires comprise of phosphor bronze centrifugally cast rims of considerable sections welded to rigid centers. Considerable versatility of shaft layout is definitely permissible with all sorts of Double Reduction systems. The dimension drawing for each series shows the different shaft handing arrangements and the correct reference should always be quoted when buying.
Our regular 700 Series – the heart of Ever-Power acceleration reducer product line – has been serving industry reliably for over 40 years. Its confirmed modular style has set the sector standard for efficiency and is the most imitated product in today’s worm gear speed reducer market. But why accept a knock-off when you can have the original – from Ever-Power.

DOUBLE REDUCTION GEAR
Ever-Power Double Decrease Worm Gear Products are constructed using two single reduction worm gear units. The primary worm gear unit is specially designed to install integrally on a standard single worm gear unit which forms the secondary stage. The entire gear unit becomes compact and rigid in arrangement for slow moving machinery. A wide range of ratio from 75:1 to 4900:1 is available. These gear units are particularly suitable for high torque slow-acceleration drives. Worm gearing conforms to BS-721.
