helical speed reducer

“EP series” inline helical gear reducers include 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. Provided in a variety of NEMA C-face quill style motor insight flange configurations, the “EP” series enables users to easily locate off-the-shelf NEMA motors instead of custom gear motors with special first pinion gears. EP’s bolt hole pattern, foundation 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.

EP Gear’s 800 Series contains a focused collection of compact, heavy duty helical gear drives that provide long-life performance and simplified maintenance. A wide range of reduction ratios match a straight broader selection of specifications, while a number of input shaft configurations maximize versatility. 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 provides a functional interchange for ep and other European manufacturers’ helical gear drives,rendering 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 standard NEMA C-face design encourage any standard NEMA engine, which makes it exceptionally versatile.
Ratios up to 70:1 in just two levels means increased efficiency and reduced case size.
Accessible oil seals simplify schedule product maintenance.
All units can be double sealed upon both input and result 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 forever which promotes trouble-free procedure.
Washdown duty products 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 a beveled gear which allows the reducer to rotate in both directions and operate with low noise and vibration. They are typically made out of durable, corrosion-resistant components 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 usage 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,floor and polished alloy metal worm develops a soft, work hardened surface area on the bronze gear. Because of this, the worm gears use in and improve with extented service while other gears are wearing out.
