GEARBOX REDUCERS
Right angle gearboxes (worm and planetary) are tough and built for 90° turns. Inline reducers (parallel shaft and planetary) are an ideal match for motors with high insight speeds, or when gearmotor performance is important. Contact our technical sales personnel for help determining which gearbox answer is best for you.
RIGHT ANGLE REDUCERS
WORM GEAR REDUCER
EP’s worm gear reducers are designed with a hollow bore and allow for a corner turn with optional dual output. The reducers can be found 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 flexibility when incorporating the reducer into product.
RIGHT ANGLE BEVEL GEARBOX
bevel-right-angle-gearbox
The proper angle bevel gearbox combines the features of our correct angle worm and planetary inline reducers. With a good and efficient right angle configuration, our right angle planetary gearboxes provide a robust solution. The right angle bevel gearbox comes in 18 ratios which range 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 small planetary gearbox configurations provide the smallest footprint and quietest operation of our quickness reducers. These gearboxes are made to deal with varying loads with little backlash. With framework sizes 52cm, 62cm, and 81cm, 12 ratios ranging from 5:1 to 308:1, we have a solution to fit your needs. Our 52 frame size is also available with plastic-type gears for noise-sensitive applications.
INLINE PLANETARY GEARBOX
inline-planetary-gearbox
Our inline planetary gearbox configurations provide the highest efficiency and best result torque of most our speed reducers. These gearboxes are made to deal with varying loads with little backlash. Planetary equipment 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 will be the top choice for continuous duty applications. Their gear cluster design provides a highly effective method for dissipating heat. Parallel shaft gearboxes have the shortest amount of our inline gear reducer options so they work very well in conditions with limited space. Our parallel shaft equipment reducers offer an affordable drop-in alternative solution for most little parallel shaft gearmotors.
Wormwheel gearboxes go by several names, including 90-degree gearboxes, right angle gearboxes, rate reducers, worm gear reducers and worm drive gearboxes. Gear reduction boxes feature a gear arrangement when a equipment in the kind of a screw, also called a worm, meshes with a worm gear. These gears are typically made from bronze and the worms are metal or stainless steel.

While worm gears act like a spur equipment, the worm gearboxes are considerably smaller than other equipment reduction boxes. A major benefit of worm equipment reducers is that they create an output that’s 90° from the input and can be used to transmit higher torque or decrease rotational speed. Most often, a worm gearbox has right hand threads; to improve the direction of the result, a left-hand thread worm gearbox is required.

Ever-Power EP series triple-reduction worm gear acceleration reducers are available in ratios from 5000:1 to 175,000:1 and center distances from 7” to 20” (larger sizes on request). Output torque ranges from 33,000 in lbs. for the 7” CD EP-70 to 582,900 in lbs for the EP-200. Mechanical HP input requirements are from 0.09 HP for the 175,000:1 7 in CD reducer to 6.25 HP for the 5000:1 20” CD unit. These reducers can be found in four configurations: horizontal, vertical, shafted, and shaft installed.

These reducers are ideal for water/waste-water apparatus drive applications such as thickeners and clarifiers, which need a vertical straight down shaft. Other offered configurations also make Ever-Power triple reduction reducers perfect for make use of on mixers, elevators, solar power panels, astronomical telescopes, indexing tables, hoists, conveyors, or various other process or components handling systems where large torques/gradual speeds are needed.

These reducers are also obtainable with a helical major reduction stage and so are termed the HDVM series

Enclosed Gears / Gearboxes
Enclosed gears, also known as gearboxes or quickness reducers, are open gears within a housing. The housing facilitates bearings and shafts, retains in lubricants, and protects the components from surrounding conditions. Gearboxes can be found in a wide range of load capacities and acceleration ratios.

The objective of a gearbox is to increase or reduce speed. As a result, torque output will be the inverse of the function. If the enclosed drive is a rate reducer, the torque output will increase; if the drive improves speed, the torque output will reduce. Gear drive selection factors include: shaft orientation, quickness ratio, design type, nature of load, gear ranking, environment, mounting position, operating temperature range, and lubrication.

Basic Types of Gearboxes

Worm Gear Speed Reducers
A single reduction speed reducer can achieve up to a 100:1 reduction ratio in a small package. Referred to as right position drives, these consist of a cylindrical worm with screw threads and a worm. With a single start worm, the worm equipment advances only 1 tooth for each 360-degree change of the worm. So, regardless of the worm’s size, the gear ratio is the ‘size of the worm equipment to 1′. Higher decrease ratios could be created by using double and triple reduction ratios.

Helical Gear Speed Reducers
Provide high-efficiency speed reduction through 1, 2, 3, or 4 sets of gears. Power is transmitted from a high-quickness pinion to a slower-speed equipment. Helical gears usually operate with their shafts parallel to each other. Both most common types will be the concentric (input and output shafts are in line) and parallel shaft (insight and output shafts are offset). Single-stage helical equipment reducers are usually used for equipment ratios up to about 8:1. Where lower speeds and higher ratios are necessary, double, triple, and quadruple gear reduction stages may be used.
