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. Offered in a number of NEMA C-encounter quill style motor input flange configurations, the “EP” series allows users to quickly locate off-the-shelf NEMA motors instead of custom gear motors with special 1st pinion gears. EP’s bolt hole pattern, base to center line elevation, result shaft diameter and usable shaft duration match the “R” group of the inline market head producing plant retrofitting a breeze.

EP Gear’s 800 Series contains a focused collection of compact, heavy duty helical gear drives that offer long-life performance and simplified maintenance. A broad selection of reduction ratios fit a straight broader range of specifications, while a number of insight shaft configurations maximize versatility. 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 offers a functional interchange for ep and other European manufacturers’ helical gear drives,making it uniquely practical for substitute 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 1 1 5/8″
The typical NEMA C-face design will accept any standard NEMA engine, making it exceptionally versatile.
Ratios up to 70:1 in just two levels means increased effectiveness and reduced case size.
Accessible oil seals simplify schedule product maintenance.
All units could be double sealed on both input and output to withstand the rigors of also 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 units in white-colored or stainless steel epoxy coatings make these gear 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 result in a drive system. They possess a beveled gear which allows the reducer to rotate in both directions and operate with low sound and vibration. They are typically crafted from durable, corrosion-resistant components like stainless steel.
Wide variety 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
Suitable for the heaviest duties

The exclusive utilization of the involute helicoid thread form on the worm and gear provides for high efficiencies and long service existence on draglines and shovels. The hardened,floor and polished alloy steel worm develops a smooth, work hardened surface on the bronze gear. Because of this, the worm gears use in and improve with extented service while other gears are wearing out.
