Double Worm Gearing
The exclusive utilization of the involute helicoid thread form on the worm and gear 
offers high efficiencies and lengthy service existence. The hardened, floor and polished alloy metal 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 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 on a standard single decrease Ever-Power worm gearbox which forms the second stage. The composite models provide the most small and rigid arrangement for large reduced amount of speed necessary for sluggish shifting machinery. A wide selection of ratios up to 4900:1 is obtainable.
Double Decrease Worm Gear Package 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 utilized ratios from the overall range of Ever-Power Double Reduction Worm Gear Box. Details of other ratios available on request.

The worm shafts are made of high 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 certainly 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 be quoted when buying.
Our regular 700 Series – the heart of Ever-Power acceleration reducer products – has been serving industry reliably for over 40 years. Its verified modular design has set the sector standard for overall performance and may be the most imitated item in the current worm gear swiftness reducer market. But why accept a double reduction worm gearbox knock-off when you can have the original – from Ever-Power.

Product Features
The 700 Series’ large 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, best 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, in addition to 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 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 existence.
Both 2D and 3D CAD drawings are available in our eCatalog.
DOUBLE REDUCTION GEAR
Ever-Power Double Decrease Worm Gear Devices are constructed using two one reduction worm gear systems. The principal worm gear device is specially designed to install integrally on a standard single worm gear unit which forms the secondary stage. The entire gear unit becomes small 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-quickness drives. Worm gearing conforms to BS-721.
