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

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

The worm shafts are made of top quality case hardening steel, accurately generated, ground and super finished. The worm wheels comprise of phosphor bronze centrifugally cast rims of substantial sections welded to rigid centers. Considerable versatility of shaft layout is usually permissible with all sorts of Double Reduction devices. The dimension drawing for every series shows the various shaft handing plans and the correct reference should always be quoted when purchasing.
Our regular 700 Series - the heart of Ever-Power swiftness reducer products - has been serving industry reliably for over 40 years. Its confirmed modular design has set the sector standard for functionality and is the most imitated item in the current worm gear speed reducer marketplace. But why settle for a knock-off when you can have the original - from Ever-Power.

Product Features
The 700 Series' huge oil reservoir provides efficient heat dissipation and lubrication for longer operating life.
Its multi-position mounting flexibility allows for installation in practically 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 optimum 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 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 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 Systems are constructed using two solitary reduction worm gear devices. The principal worm gear unit is specially made to attach integrally on a standard single worm gear unit which forms the secondary stage. The complete gear unit becomes compact and rigid in arrangement for slow moving machinery. A wide variety 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.
