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 casing for unquestioned strength and reliability. Provided in a number of NEMA C-encounter quill style motor input flange configurations, the “EP” series enables users to easily locate off-the-shelf NEMA motors in lieu of custom equipment motors with special 1st pinion gears. EP’s bolt hole pattern, foundation to center line height, 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 collection of compact, heavy duty helical equipment drives that provide long-existence performance and simplified maintenance. A wide range of reduction ratios suit an even broader selection of specifications, while a variety of input shaft configurations maximize flexibility. In addition, the amount of products that enhance this series of gear drives make it a perfect choice for today’s industrial distributor.
The 800 Series provides a functional interchange for ep and other European producers’ helical gear drives,making 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 1 1 5/8″
The standard NEMA C-face design encourage any standard NEMA electric motor, making it exceptionally versatile.
Ratios up to 70:1 in only two stages means increased efficiency and reduced case size.
Available oil seals simplify regimen product maintenance.
All units can be double sealed upon both input and result to withstand the rigors of even 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 devices in white or stainless epoxy coatings make these gear drives well suited for the most serious Washdown.
Correct angle bevel speed reducers decrease speed and increase torque from the driver end to the driven result in a drive system. They have got a beveled gear that allows the reducer to rotate in both directions and operate with low noise and vibration. They are usually crafted from durable, corrosion-resistant components like stainless steel.
Wide range of accessories and nonstandard designs
Single piece housing with high structural stiffness
Easy and functional shaft-mounting design
Minimum maintenance requirements
High, reliable and tested performance
Ideal for the heaviest duties
This economical aluminum body helical speed reducer provides highly reliable power transmission for general purpose applications. These gearboxes offer cost effective operation and superior efficiency over similar products.
5 sizes with aluminum housings
Torque capacity from 200-6000 inlbs
Ratios from 2.5:1 to 600:1
Output shafts in ” or metric dimensions
Input 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 offers high efficiencies and lengthy service existence on draglines and shovels. The hardened,floor and polished alloy metal worm develops a clean, work hardened surface area on the bronze equipment. Because of this, the worm gears put on in and improve with prolonged service while various other gears are deteriorating.
Hardened, shaved or floor helical gears
Hollow & solid output shafts
Vertical & horizontal mountings
Fan cooled (standard)
Motor mounts
Cast iron or steel housings available
