Worm Gear Reducer

Single reduction worm gearing offers high ratio reduction with couple of moving parts in a close-coupled compact drive. The right angle arrangement of driving-to-driven machine requires a minimum of space. Input and result shafts can be extended in either or both directions in horizontal or vertical plans adaptable to any installation requirement. Efficient engine speeds are reduced to slower speed requirements of many industrial machines in one reduction.

The exclusive use of the involute Helicoid Thread form (with leaving side contact) on the worm and gear provides for high efficiencies, and long service existence. The hardened surface and polished alloy metal worm develops a soft, work hardened surface area on the bronze gear. Because of this worm gears wear in and improve with extented service while other gears are wearing out. Ever-Power offers a wide selection of model configurations, sizes, ratios, and add-ons from our standard products.

Fabricated Designs
If the application involves serious shock loads or possible housing damage from external sources (as in steel mills or mobile apparatus applications) Ever-Power can provide fabricated steel housings with up to 48″ center distances. Fabricated housings provide maximum rigidity and strength which allows the transmission of higher horsepower levels than are possible with worm gear reduer regular cast iron devices. Extra heavy aspect plates connect the worm and equipment shaft bearing facilitates, assuring proper meshing of the gear under all load conditions. In smaller sized sizes, fabricated metal reducers are interchangeable with Ever-Power regular cast iron reducers.

Custom Designs
Ever-Power can provide custom quickness and reversed engineered reducers for the application, be it a fresh project or a primary drop-in alternative to a competitor's speed reducer. Fabricated steel reducers allow Ever-Power to complement a competitor's footprint, centerline, and shaft elevation allowing a primary drop-in alternative saving the customer time and money.
