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, floor and polished alloy metal worm develops a easy, work hardened surface on the bronze equipment. For this reason, the worm gears wear in and improve with extented service while 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 second stage. The composite units provide the most compact and rigid arrangement for large reduced amount of speed necessary for slow moving machinery. A wide range of ratios up to 4900:1 is obtainable.
Double Reduction Worm Gear Container 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 overall range of Ever-Power Double Reduction Worm Gear Box. Information on other ratios on request.

The worm shafts are made from high quality case hardening steel, accurately generated, ground and super finished. The worm tires comprise of phosphor bronze centrifugally cast rims of considerable sections welded to rigid centers. Considerable flexibility of shaft layout can be permissible with all sorts of Double Reduction systems. The dimension drawing for every double reduction worm gearbox 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 speed reducer products – has been serving industry reliably for over 40 years. Its tested modular design has set the industry standard for efficiency and may be the most imitated item in today’s worm gear quickness reducer market. But why settle for a knock-off when you’re able to have the original – 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 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 casing, 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, 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 are available in our eCatalog.
DOUBLE REDUCTION GEAR
Ever-Power Double Reduction Worm Gear Products are constructed using two one reduction worm gear products. The primary worm gear device is specially designed to mount integrally on a typical single worm gear unit which forms the secondary stage. The entire gear unit becomes small and rigid in set up for slow moving machinery. A wide variety of ratio from 75:1 to 4900:1 is available. These equipment units are particularly ideal for high torque slow-speed drives. Worm gearing conforms to BS-721.
