Double Worm Gearing
The exclusive utilization of the involute helicoid thread form on the worm and gear provides for high efficiencies and lengthy service lifestyle. The hardened, surface and polished alloy steel worm develops a soft, work hardened surface area on the bronze gear. Because of this, the worm gears put on in and improve with prolonged service while various other gears are wearing out.

ouble Reduction Worm Gearbox
Ever-Power Double Decrease Worm Gearboxes are two stage worm decrease units.
A specifically designed primary worm decrease device is integrally mounted on a standard single reduction Ever-Power worm gearbox which forms the second 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 obtainable.
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 collection of commonly used ratios from the entire range of Ever-Power Dual Reduction Worm Gear Box. Details of other ratios on request.

The worm shafts are made of top quality case hardening steel, accurately generated, ground and super 
finished. The worm tires comprise of phosphor bronze centrifugally cast rims of significant sections welded to rigid centers. Considerable flexibility of shaft layout is permissible with all types of Double Reduction models. The dimension drawing for every series shows the different shaft handing plans and the correct reference should always be quoted when buying.
Our standard 700 Series – the heart of Ever-Power velocity reducer products – has been serving industry reliably for over 40 years. Its confirmed modular style has set the industry standard for performance and may be the most imitated item in today’s worm gear acceleration 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 lifestyle.
Its multi-position mounting flexibility permits installation in virtually 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, 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 increase thrust and overhung load capacities, sizes 713-760.
Our 700 Series’ high-strength steel result shaft assures capacity for high torque and overhung loads.
Pipe plugs allow easy fill, level, and drain in virtually 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 can be found in our eCatalog.
DOUBLE REDUCTION GEAR
Ever-Power Double Reduction Worm Gear Units are constructed using two solitary reduction worm gear products. The primary worm gear device is specially made to install integrally on a typical single worm gear unit which forms the secondary stage. The complete 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 suitable for high torque slow-swiftness drives. Worm gearing conforms to BS-721.
