double reduction worm gearbox

Double Worm Gearing
The exclusive utilization of the involute helicoid thread form on the worm and gear offers high efficiencies and long service lifestyle. The hardened, floor and polished alloy metal worm develops a easy, work hardened double reduction worm gearbox surface area on the bronze equipment. Because of this, 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 specially designed primary worm reduction unit is integrally mounted upon 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 reduction of speed necessary for slower moving machinery. A wide range of ratios up to 4900:1 is offered.
Double Decrease 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 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 types of Double Reduction systems. The dimension drawing for each series shows the different shaft handing arrangements and the appropriate reference should be quoted when buying.
Our standard 700 Series – the heart of Ever-Power rate reducer products – has been serving industry reliably for over 40 years. Its proven modular style has set the industry standard for efficiency and is the most imitated product in today’s worm gear quickness reducer marketplace. But why settle for a knock-off when you can have the initial – from Ever-Power.

Product Features
The 700 Series’ huge oil reservoir provides efficient heat dissipation and lubrication for longer operating existence.
Its multi-position mounting flexibility allows for installation in practically any position.
Housings are straddle-milled, top and bottom, 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 maximum durability, as well as 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 improve thrust and overhung load capacities, sizes 713-760.
Our 700 Series’ high-strength steel result shaft assures capacity for 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 life.
Both 2D and 3D CAD drawings can be found in our eCatalog.
DOUBLE REDUCTION GEAR
Ever-Power Double Reduction Worm Gear Products are constructed using two single reduction worm gear models. The primary worm gear device is specially made to mount integrally on a standard single worm gear device which forms the secondary stage. The complete gear unit becomes compact and rigid in set up 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-acceleration drives. Worm gearing conforms to BS-721.
