Double Worm Gearing
The exclusive usage 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 simple, work hardened surface on the bronze equipment. For this reason, the worm gears use in and improve with extented service while other gears are deteriorating.

ouble Reduction Worm Gearbox
double reduction worm gearbox Ever-Power Double Reduction Worm Gearboxes are two stage worm decrease units.
A specially designed primary worm decrease unit is integrally mounted on a standard single reduction Ever-Power worm gearbox which forms the next stage. The composite systems provide the most small and rigid set up for large reduction of speed necessary for slow moving machinery. A wide variety of ratios up to 4900:1 is offered.
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 selection of commonly utilized ratios from the overall range of Ever-Power Double Reduction Worm Gear Box. Details of other ratios on request.

The worm shafts are made of high quality case hardening steel, accurately generated, ground and super finished. The worm wheels comprise of phosphor bronze centrifugally cast rims of significant sections welded to rigid centers. Considerable versatility of shaft layout is permissible with all sorts of Double Reduction products. The dimension drawing for each 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 speed reducer product line – has been serving industry reliably for over 40 years. Its tested modular design has set the sector standard for overall performance and may be the most imitated product in the current worm gear quickness reducer marketplace. 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 life.
Its multi-position mounting flexibility permits 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 casing, fabricated of fine-grained, gear-quality cast iron, provides maximum 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 output shaft assures convenience of high torque and overhung loads.
Pipe plugs allow easy fill, level, and drain in 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 Decrease Worm Gear Models are constructed using two solitary reduction worm gear units. The principal worm gear device is specially made to mount integrally on a typical single worm gear unit which forms the secondary stage. The entire 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 ideal for high torque slow-speed drives. Worm gearing conforms to BS-721.
