Double Worm Gearing
The exclusive utilization of the involute helicoid thread form on the worm and gear offers high efficiencies and long service existence. The hardened, ground and polished alloy steel worm develops a easy, work hardened surface on the bronze equipment. Because of this, the worm gears use in and improve with extented service while various other gears are deteriorating.

Ever-Power Double Reduction Worm Gearboxes are two stage worm decrease units.
A specifically designed primary worm decrease device is integrally mounted on a standard single decrease Ever-Power worm gearbox which forms the second stage. The composite units provide the most small and rigid set up for large reduction of speed necessary for slower shifting machinery. A wide range of ratios up to 4900:1 is available.
Double Decrease 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 are a typical collection of commonly used ratios from the overall range of Ever-Power Dual Reduction Worm Gear Box. Information on other ratios on request.

The worm shafts are constructed with top quality case hardening steel, accurately generated, ground and super finished. The worm tires comprise of phosphor bronze centrifugally cast rims of substantial sections welded to rigid centers. Considerable versatility of shaft layout is certainly permissible with all types of Double Reduction models. The dimension drawing for each series shows the different shaft handing plans and the appropriate reference should always be quoted when ordering.
Our standard 700 Series – the heart of Ever-Power quickness reducer products – has been serving industry reliably for over 40 years. Its confirmed modular design has set the sector standard for overall performance and is the most imitated item in today’s worm gear speed reducer market. But why settle for a knock-off when you can have the original – from Ever-Power.

The 700 Series’ huge oil reservoir double reduction worm gearbox provides efficient heat dissipation and lubrication for longer operating lifestyle.
Its multi-position mounting flexibility allows for installation in practically 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 maximum strength for maximum durability, along with 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 output shaft assures capacity for 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 life.
Both 2D and 3D CAD drawings are available in our eCatalog.
DOUBLE REDUCTION GEAR
Ever-Power Double Decrease Worm Gear Models are constructed using two solitary reduction worm gear products. The primary worm gear unit is specially designed to mount integrally on a standard single worm gear unit which forms the secondary stage. The entire gear unit becomes small and rigid in set up for slow shifting machinery. A wide selection of ratio from 75:1 to 4900:1 is available. These equipment units are particularly suitable for high torque slow-velocity drives. Worm gearing conforms to BS-721.
