helical speed reducer

“EP series” inline helical equipment reducers feature a HP range of ¼-100 HP, 37-147 mm box sizes, 2:1-120:1 speed ratios and a cast iron housing for unquestioned strength and reliability. Offered in a number of NEMA C-face quill style motor input flange configurations, the “EP” series enables users to very easily locate off-the-shelf NEMA motors in lieu of custom gear motors with special initial pinion gears. EP’s bolt hole pattern, bottom to center line elevation, output shaft diameter and usable shaft length match the “R” series of the inline market leader making plant retrofitting a breeze.

EP Gear’s 800 Series contains a focused selection of compact, durable helical equipment drives that provide long-existence performance and simplified maintenance. A broad selection of reduction ratios suit an even broader range of specifications, while a number of input shaft configurations maximize flexibility. In addition, the number of products that complement this series of equipment drives make it an ideal choice for today’s commercial distributor.
The 800 Series provides a functional interchange for ep and other European manufacturers’ 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 output flange-mount models available
Output-shaft diameters from 3/4″ to at least one 1 5/8″
The typical NEMA C-face design will accept any standard NEMA electric motor, which makes it exceptionally versatile.
Ratios up to 70:1 in only two phases means increased efficiency and reduced case size.
Accessible oil seals simplify schedule product maintenance.
All units can be double sealed on both input and output 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 for life which promotes trouble-free procedure.
Washdown duty devices in white-colored or stainless steel epoxy coatings make these equipment drives well suited for the most severe Washdown.
Correct angle bevel speed reducers decrease speed and increase torque from the driver end to the driven end in a drive system. They have a beveled gear that allows the reducer to rotate in both directions and operate with low noise and vibration. They are typically crafted from durable, corrosion-resistant materials like stainless steel.
Features
Wide range of accessories and non-standard designs
Single piece housing with high structural stiffness
Benefits
Easy and functional shaft-mounting design
Minimum maintenance requirements
High, reliable and tested performance
Suitable for the heaviest duties
This economical aluminum body helical speed reducer provides highly reliable power transmission for general purpose applications. These gearboxes offer affordable operation and superior performance over similar products.

Torque capacity from 200-6000 inlbs
Ratios from 2.5:1 to 600:1
Output shafts in in . or metric dimensions
Insight adapters for NEMA and IEC motors
Mounting via foot, face or bolt-on flange
The exclusive use of the involute helicoid thread form on the worm and gear provides for high efficiencies and lengthy service lifestyle on draglines and shovels. The hardened,surface and polished alloy metal worm develops a even, work hardened surface area on the bronze gear. Because of this, the worm gears wear in and improve with prolonged service while additional gears are deteriorating.
Hardened, shaved or surface helical gears
Hollow & solid output shafts
Vertical & horizontal mountings
Fan cooled (standard)
Motor mounts
Cast iron or steel housings available
