Double Worm Gearing
The exclusive usage of the involute helicoid thread form on the worm and gear offers high efficiencies and lengthy service lifestyle. The hardened, surface and polished alloy metal worm develops a clean, work hardened surface on the bronze gear. For this reason, the worm gears wear in and improve with prolonged service while additional gears are deteriorating.

ouble Reduction Worm Gearbox
Ever-Power Double Reduction Worm Gearboxes are two stage worm decrease units.
A specifically designed primary worm decrease device is integrally mounted upon a standard single decrease Ever-Power worm gearbox which forms the next stage. The composite units provide the most small and rigid set up for large reduced amount of speed necessary for sluggish shifting machinery. A wide range of ratios up to 4900:1 is available.
Double Decrease Worm Gear Package Sizes Available around 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 are a typical collection of commonly used ratios from the entire range of Ever-Power Dual Reduction Worm Gear Box. Information on other ratios on request.

The worm double reduction worm gearbox shafts are made of high quality case hardening steel, accurately generated, ground and super finished. The worm wheels comprise of phosphor bronze centrifugally cast rims of considerable sections welded to rigid centers. Considerable versatility of shaft layout is usually permissible with all types of Double Reduction models. The dimension drawing for every series shows the various shaft handing arrangements and the appropriate reference should be quoted when ordering.
Our standard 700 Series – the heart of Ever-Power rate reducer product line – has been serving industry reliably for over 40 years. Its tested modular design has set the industry standard for functionality and is the most imitated item in the current worm gear swiftness reducer market. But why accept a knock-off when you’re able to have the initial – from Ever-Power.

Product Features
The 700 Series’ large oil reservoir provides efficient heat dissipation and lubrication for longer operating life.
Its multi-position mounting flexibility permits installation in practically any position.
Housings are straddle-milled, top and bottom, for precise alignment of horizontal and vertical bases.
Internal baffles assure positive, leak-free venting.
The 700 Series’ rugged housing, fabricated of fine-grained, gear-quality cast iron, provides optimum strength for optimum durability, as well as greater precision during worm and gear alignment.
Ever-Power’s 700 Series high-strength bronze worm gear is straddle mounted between heavy-duty tapered roller bearings to improve thrust and overhung load capacities, sizes 713-760.
Our 700 Series’ high-strength steel output shaft assures capacity for high torque and overhung loads.
Pipe plugs allow easy fill, level, and drain in any mounting position.
The 700 Series’ super-finished oil-seal diameters on both input and output shafts extend seal lifestyle.
Both 2D and 3D CAD drawings are available in our eCatalog.
DOUBLE REDUCTION GEAR
Ever-Power Double Reduction Worm Gear Systems are constructed using two single reduction worm gear devices. The principal worm gear device is specially designed to attach integrally on a typical single worm gear device which forms the secondary stage. The complete gear unit becomes compact and rigid in set up for slow moving machinery. A wide selection of ratio from 75:1 to 4900:1 is available. These equipment units are particularly suitable for high torque slow-quickness drives. Worm gearing conforms to BS-721.
