Product Features
The 700 Series’ huge oil reservoir provides efficient heat dissipation and lubrication for longer operating existence.
Its multi-position mounting versatility permits installation in virtually any position.
Housings are straddle-milled, top and bottom level, for precise alignment of horizontal and vertical bases.
Internal baffles assure positive, leak-free venting.
The 700 Series’ rugged casing, fabricated of fine-grained, gear-quality cast iron, provides optimum strength for maximum durability, as well as greater precision during worm and gear alignment.
EP Gear’s 700 Series high-strength bronze worm equipment is straddle mounted between heavy-duty tapered roller bearings to improve thrust and overhung load capacities, sizes 713-760.
Our 700 Series’ high-strength steel output shaft assures convenience of high torque and overhung loads.
Pipe plugs allow easy fill up, level, and drain in any mounting position.
The 700 Series’ super-finished oil-seal diameters on both input and output shafts extend seal lifestyle.
Both 2D and 3D CAD drawings are available in our eCatalog.
GEARBOX REDUCERS
Correct angle gearboxes (worm and planetary) are durable and built for 90° turns. Inline reducers (parallel shaft and planetary) are a perfect match for motors with high insight speeds, or when gearmotor efficiency is important. Contact our technical sales staff for help identifying which gearbox answer is best for you.
RIGHT ANGLE REDUCERS
WORM GEAR REDUCER
EP’s worm equipment reducers were created with a hollow bore and invite for a corner change with optional dual result. The reducers come in 12 ratios ranging from 5:1 to 100:1, with non-back-drivable ratios 30:1 and higher. Our correct angle gearboxes are designed with five mounting options providing versatility when incorporating the reducer into product.
RIGHT ANGLE BEVEL GEARBOX
bevel-right-angle-gearbox
The proper angle bevel gearbox combines the top features of our correct angle worm and planetary inline reducers. With a solid and efficient correct angle configuration, our right angle planetary gearboxes offer a robust solution. The proper angle bevel gearbox will come in 18 ratios ranging from 5:1 to 1000:1, in fact it is back-drivable at all ratios.
INLINE REDUCERS
I-SERIES PLANETARY GEARBOX
i-series-planetary-gearbox
Our I-Series little planetary gearbox configurations supply the smallest footprint and quietest operation of our rate reducers. These gearboxes are created to manage varying loads with small backlash. With framework sizes 52cm, 62cm, and 81cm, 12 ratios which range from 5:1 to 308:1, we’ve a solution to suit your needs. Our 52 frame size can be available with plastic-type material gears for noise-delicate applications.
INLINE PLANETARY GEARBOX
inline-planetary-gearbox
Our inline planetary gearbox configurations supply the highest efficiency and best output torque of most our quickness reducers. These gearboxes are created to handle varying loads with small backlash. Planetary gear reducers operate more quietly than parallel shaft reducers. With 18 ratio options ranging from 5:1 to 1000:1, we’ve a solution to suit your needs.
PARALLEL SHAFT GEARBOX
parallel-shaft-gearbox
Parallel shaft gearboxes are the top choice for continuous duty applications. Their equipment cluster design provides a highly effective method for dissipating temperature. Parallel shaft gearboxes possess the shortest amount of our inline gear reducer options therefore they work very well in environments with limited space. Our parallel shaft equipment reducers offer an affordable drop-in substitute solution for most little parallel shaft gearmotors.
Wormwheel gearboxes pass several names, including 90-degree gearboxes, right position gearboxes, speed reducers, worm equipment reducers and worm drive gearboxes. Gear reduction boxes feature a gear arrangement when a equipment in the kind of a screw, also referred to as a worm, meshes with a worm equipment. These gears are usually made from bronze and the worms are metal or stainless steel.

While worm gears act like a spur gear, the worm gearboxes are significantly smaller than other equipment reduction boxes. A primary benefit of worm gear reducers is certainly that they produce an output that’s 90° from the input and can be utilized to transmit higher torque or decrease rotational speed. Frequently, a worm gearbox provides right hand threads; to improve the path of the result, a left-hand thread worm gearbox is necessary.
