Double Worm Gearing
The exclusive utilization of the involute helicoid thread form on the worm and gear offers high efficiencies and long service life. The hardened, floor and polished alloy metal worm develops a clean, work hardened surface on the bronze equipment. Because of this, the worm gears put on 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 decrease units.
A specifically designed primary worm decrease unit is integrally mounted upon a standard single decrease Ever-Power worm gearbox which 
forms the second stage. The composite units provide the most small and rigid arrangement for large reduction of speed necessary for slower moving machinery. A wide variety of ratios up to 4900:1 is obtainable.
Double Reduction Worm Gear Container 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 certainly are a typical collection of commonly utilized ratios from the entire range of Ever-Power Double Reduction Worm Gear Box. Information on other ratios available on request.

motor – optional
The worm shafts are made from top 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 definitely permissible with all types of Double Reduction models. The dimension drawing for every series shows the different shaft handing arrangements and the appropriate reference should always be quoted when buying.
Our regular 700 Series – the heart of Ever-Power quickness reducer products – has been serving industry reliably for over 40 years. Its tested modular style has set the market standard for efficiency and is the most imitated item in the current worm gear quickness reducer marketplace. But why accept a knock-off when you’re able to have the original – from Ever-Power.

Product Features
The 700 Series’ huge oil reservoir provides efficient heat dissipation and lubrication for longer operating life.
Its multi-position mounting flexibility allows for 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 maximum durability, and also 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 result shaft assures convenience of 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.
Both 2D and 3D CAD drawings can be found in our eCatalog.
DOUBLE REDUCTION GEAR
Ever-Power Double Decrease Worm Gear Products are constructed using two single reduction worm gear devices. The principal worm gear device is specially made to install integrally on a typical single worm gear unit which forms the secondary stage. The entire gear unit becomes compact and rigid in arrangement for slow shifting machinery. A wide selection of ratio from 75:1 to 4900:1 is available. These gear units are particularly ideal for high torque slow-quickness drives. Worm gearing conforms to BS-721.
