Double Worm Gearing
The exclusive utilization of the involute helicoid thread form on the worm and gear offers high efficiencies and long service lifestyle. The hardened, surface and polished alloy steel worm develops a even, work hardened surface area on the bronze gear. For this reason, the worm gears use in and improve with prolonged service while various other gears are deteriorating.

ouble Reduction Worm Gearbox
Ever-Power Double Decrease Worm Gearboxes are two stage worm reduction units.
A specifically designed primary worm decrease unit is integrally mounted upon a standard single reduction Ever-Power worm gearbox which forms the next stage. The composite models provide the most compact and rigid set up for large reduction of speed necessary for slower moving machinery. A wide range of ratios up to 4900:1 is obtainable.
Double Decrease Worm Gear Box 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 utilized ratios from the entire range of Ever-Power Double Reduction Worm Gear Box. Details of other ratios available on request.

The worm shafts are made from high quality case hardening steel, accurately generated, ground and super finished. The worm wheels comprise of phosphor bronze centrifugally cast rims of substantial sections welded to rigid centers. Considerable flexibility of shaft layout is certainly permissible with all sorts of Double Reduction units. The dimension drawing for every series shows the various shaft 
handing plans and the appropriate reference should always be quoted when purchasing.
Our standard 700 Series – the heart of Ever-Power swiftness reducer products – has been serving industry reliably for over 40 years. Its tested modular style has set the industry standard for performance and may be the most imitated product in today’s worm gear acceleration reducer market. But why settle for a knock-off when you can 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 allows for installation in virtually any position.
Housings are straddle-milled, best and bottom level, 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, in addition to 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 increase 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 up, level, and drain in virtually any mounting position.
The 700 Series’ super-finished oil-seal diameters on both input and output shafts extend seal lifestyle.

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