Solitary reduction worm gearing provides high ratio reduction with few shifting parts in a close-coupled small drive. The proper angle arrangement of driving-to-driven machine takes a minimum of space. Input and output shafts can be extended in either or both directions in horizontal or vertical arrangements adaptable to any mounting requirement. Efficient engine speeds are decreased to slow speed requirements of many industrial machines in one reduction.

The exclusive usage of the involute Helicoid Thread form (with leaving side contact) on the worm and gear provides for high efficiencies, and long service life. The hardened floor and polished alloy metal worm develops a clean, work hardened surface on the bronze gear. For this reason worm gears use in and improve with prolonged service while various other gears are deteriorating. Ever-Power offers a wide selection of model configurations, sizes, ratios, and components from our standard products.

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

Custom Designs
Ever-Power can offer custom quickness and reversed engineered reducers for your application, be it a fresh project or a direct drop-in alternative to a competitor’s rate reducer. Fabricated metal reducers enable Ever-Power to match a competitor’s footprint, centerline, and shaft height allowing a primary drop-in replacement saving the customer time and money.
