helical speed reducer

“EP series” inline helical equipment reducers include a HP selection 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. Provided in a number of NEMA C-encounter quill style motor input flange configurations, the “EP” series enables users to quickly locate off-the-shelf NEMA motors instead of custom gear motors with special initial pinion gears. EP’s bolt hole pattern, base to center line elevation, result shaft diameter and usable shaft size match the “R” group of the inline market innovator producing plant retrofitting a breeze.

The precision planetary gear units of the EP series with floor helical gearing and preloaded dual taper roller bearings assure low-noise synchronism because of their immense load transporting capacity and rigidity even under high load conditions. The one-piece world carrier and the included needle roller bearings allow the transmission of high torques. The excess shaft sealing band ensures maximum protection against dirt and splash water relative to protection class IP65.

EP Gear’s 800 Series contains a focused collection of compact, durable helical gear drives that provide long-life performance and simplified maintenance. A wide selection of reduction ratios match a straight broader range of specifications, while a variety of input shaft configurations maximize flexibility. In addition, the amount of products that complement this series of equipment drives make it an ideal choice for today’s industrial distributor.
The 800 Series offers 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 output flange-mount models available
Output-shaft diameters from 3/4″ to at least one 1 5/8″
The standard NEMA C-face design encourage any standard NEMA engine, which makes it exceptionally versatile.
Ratios up to 70:1 in just two phases means increased performance and reduced case size.
Available oil seals simplify schedule product maintenance.
All units can be double sealed on both the input and output to withstand the rigors of actually the most demanding applications.
800 Series drives come pre-filled with synthetic lubrication for your unique mounting position.
Sizes 3 and 4 are lubricated for life which promotes trouble-free operation.
Washdown duty products in white or stainless steel epoxy coatings make these gear drives perfect for the most severe Washdown.
Right angle bevel speed reducers decrease speed and increase torque from the driver end to the driven result in a drive system. They have a beveled gear which allows the reducer to rotate in both directions and operate with low sound and vibration. They are typically made out of durable, corrosion-resistant components like stainless steel.
Wide range of accessories and non-standard designs
Single piece casing with high structural stiffness
Easy and functional shaft-mounting design
Minimum maintenance requirements
High, reliable and tested performance
Ideal for the heaviest duties

The exclusive utilization of the involute helicoid thread form on the worm and gear offers high efficiencies and long service lifestyle on draglines and shovels. The hardened,floor and polished alloy metal worm develops a easy, work hardened surface area on the bronze gear. For this reason, the worm gears wear in and improve with extented service while additional gears are deteriorating.

Hollow & solid output shafts
Vertical & horizontal mountings
Fan cooled (standard)
Motor mounts
Cast iron or steel housings available
