Double Worm Gearing
The exclusive use of the involute helicoid thread form on the worm and gear provides for high efficiencies and lengthy service life. The hardened, surface and polished alloy steel worm develops a clean, work hardened surface on the bronze gear. Because of this, the worm gears wear in and improve with extented service while additional gears are deteriorating.

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

The worm shafts are constructed with high quality case hardening steel, accurately generated, ground and super finished. The worm wheels comprise of phosphor bronze centrifugally cast rims of significant sections welded to rigid centers. Considerable flexibility of shaft layout is definitely permissible with all sorts of Double Reduction models. The dimension drawing for each series shows the various shaft handing plans and the correct double reduction worm gearbox reference should be quoted when buying.
Our regular 700 Series – the heart of Ever-Power rate reducer product line – has been serving industry reliably for over 40 years. Its confirmed modular design has set the industry standard for overall performance and may be the most imitated item in the current 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 existence.
Its multi-position mounting flexibility permits installation in virtually any position.
Housings are straddle-milled, top 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 maximum strength for optimum durability, along with greater precision during worm and gear alignment.
Ever-Power’s 700 Series high-strength bronze worm equipment 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 result shaft assures convenience of 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 existence.
Both 2D and 3D CAD drawings are available in our eCatalog.
DOUBLE REDUCTION GEAR
Ever-Power Double Reduction Worm Gear Models are constructed using two solitary reduction worm gear products. The principal worm gear device is specially designed to attach integrally on a standard single worm gear device which forms the secondary stage. The entire gear unit becomes small and rigid in arrangement 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-acceleration drives. Worm gearing conforms to BS-721.
