helical speed reducer

“EP series” inline helical gear reducers feature a HP selection of ¼-100 HP, 37-147 mm box sizes, 2:1-120:1 speed ratios and a cast iron casing for unquestioned strength and reliability. Provided in a variety of NEMA C-encounter quill style motor input flange configurations, the “EP” series enables users to very easily locate off-the-shelf NEMA motors instead of custom equipment motors with special first pinion gears. EP’s bolt hole pattern, bottom to center line height, output shaft diameter and usable shaft size match the “R” series of the inline market innovator making plant retrofitting a breeze.

EP Gear’s 800 Series contains a focused collection of compact, durable helical equipment drives that provide long-existence performance and simplified maintenance. A wide range of reduction ratios suit an even broader range of specifications, while a variety of input shaft configurations maximize versatility. In addition, the amount of products that enhance this series of equipment drives make it an ideal choice for today’s industrial distributor.
The 800 Series provides a functional interchange for ep and other European producers’ helical gear drives,rendering it uniquely practical for alternative applications.
Four basic sizes 1/6 – 10 HP
Over 40 different ratios 1.5:1 – 71:1 double-reduction ratios 36:1 – 250:1 triple-reduction ratios
Non-flanged and NEMA c-face input styles
Base-mount and result flange-mount models available
Output-shaft diameters from 3/4″ to at least one 1 5/8″
The typical NEMA C-face design encourage any standard NEMA motor, making it exceptionally versatile.
Ratios up to 70:1 in only two phases means increased efficiency and reduced case size.
Available oil seals simplify routine product maintenance.
All units can be double sealed upon both the input and result to withstand the rigors of actually the most demanding applications.
800 Series drives come pre-filled with synthetic lubrication for your specific mounting position.
Sizes 3 and 4 are lubricated forever which promotes trouble-free operation.
Washdown duty products in white-colored or stainless epoxy coatings make these equipment drives ideal for the most serious Washdown.
Right angle bevel speed reducers decrease speed and increase torque from the driver end to the driven end in a drive system. They have got a beveled gear that allows the reducer to rotate in both directions and operate with low sound and vibration. They are usually made out of durable, corrosion-resistant materials like stainless steel.
Wide range of accessories and nonstandard designs
Single piece casing with high structural stiffness
Easy and functional shaft-mounting design
Minimum maintenance requirements
High, reliable and tested performance
Suitable for the heaviest duties

The exclusive use of the involute helicoid thread form on the worm and gear offers high efficiencies and lengthy service life on draglines and shovels. The hardened,surface and polished alloy steel worm develops a soft, work hardened surface area on the bronze equipment. For this reason, the worm gears put on in and improve with extented service while various other gears are deteriorating.
Hardened, shaved or ground helical gears
Hollow & solid output shafts
Vertical & horizontal mountings
Fan cooled (standard)
Motor mounts
Cast iron or steel housings available
