GEARBOX REDUCERS
Right 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. Get in touch with our technical sales staff for help determining which gearbox option is best for you.
RIGHT ANGLE REDUCERS
WORM GEAR REDUCER
EP’s worm equipment reducers are designed with a hollow bore and invite for a corner turn with optional dual result. The reducers can be found in 12 ratios which range from 5:1 to 100:1, with non-back-drivable ratios 30:1 and higher. Our right angle gearboxes were created with five mounting options providing versatility when incorporating the reducer into product.
RIGHT ANGLE BEVEL GEARBOX
bevel-right-angle-gearbox
The right angle bevel gearbox combines the features of our right angle worm and planetary inline reducers. With a good and efficient correct angle configuration, our right angle planetary gearboxes offer a robust solution. The right angle bevel gearbox will come in 18 ratios which range from 5:1 to 1000:1, and it is back-drivable at all ratios.
INLINE REDUCERS
I-SERIES PLANETARY GEARBOX
i-series-planetary-gearbox
Our I-Series small planetary gearbox configurations supply the smallest footprint and quietest operation of our rate reducers. These gearboxes are made to handle varying loads with small backlash. With frame 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 can be available with plastic-type gears for noise-delicate applications.
INLINE PLANETARY GEARBOX
inline-planetary-gearbox
Our inline planetary gearbox configurations provide the highest performance and best result torque of most our speed reducers. These gearboxes are designed to deal with varying loads with little backlash. Planetary equipment reducers operate more quietly than parallel shaft reducers. With 18 ratio choices 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 best choice for continuous duty applications. Their gear cluster design provides an effective method for dissipating high temperature. Parallel shaft gearboxes have the shortest amount of our inline equipment reducer options so they work well in conditions with limited space. Our parallel shaft gear reducers provide an affordable drop-in replacement solution for most little parallel shaft gearmotors.
Wormwheel gearboxes pass several names, including 90-degree gearboxes, right angle gearboxes, quickness reducers, worm gear reducers and worm drive gearboxes. Gear decrease boxes feature a gear arrangement in which a gear in the form of a screw, also called a worm, meshes with a worm gear. These gears are typically created from bronze and the worms are metal or stainless steel.

While worm gears are similar to a spur gear, the worm gearboxes are significantly smaller than other equipment reduction boxes. A primary benefit of worm equipment reducers is definitely that they create an output that is 90° from the input and can be utilized to transmit higher torque or decrease rotational speed. Frequently, a worm gearbox has right hand threads; to change the direction of the output, a left-hand thread worm gearbox is necessary.

Ever-Power EP series triple-reduction worm gear velocity reducers can be found in ratios from 5000:1 to 175,000:1 and center distances from 7” to 20” (larger sizes available on request). Result torque ranges from 33,000 in pounds. for the 7” CD EP-70 to 582,900 in lbs for the EP-200. Mechanical HP insight 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 mounted.

These reducers are well suited for water/waste-water products drive applications such as for example thickeners and clarifiers, which require a vertical down shaft. Other available configurations also make Ever-Power triple reduction reducers perfect for use on mixers, elevators, solar panels, astronomical telescopes, indexing tables, hoists, conveyors, or other process or components handling systems where large torques/slower speeds are needed.

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

Enclosed Gears / Gearboxes
Enclosed gears, also known as gearboxes or velocity reducers, are open gears within a housing. The casing facilitates bearings and shafts, keeps in lubricants, and protects the elements from surrounding circumstances. Gearboxes can be found in a wide variety of load capacities and acceleration ratios.

The objective of a gearbox is to increase or reduce speed. Because of this, torque output would be the inverse of the function. If the enclosed drive is definitely a rate reducer, the torque output increase; if the drive increases speed, the torque output will decrease. Gear drive selection elements include: shaft orientation, velocity ratio, design type, nature of load, gear rating, environment, mounting position, operating temperature range, and lubrication.

Basic Types of Gearboxes

Worm Gear Speed Reducers
A single reduction rate reducer can achieve up to a 100:1 decrease ratio in a small package. Referred to as right position drives, these contain a cylindrical worm with screw threads and a worm. With a single begin worm, the worm equipment advances only one tooth for each 360-degree convert of the worm. So, whatever the worm’s size, the apparatus 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 units of gears. Power is transmitted from a high-velocity pinion to a slower-speed equipment. Helical gears generally operate with their shafts parallel to each other. The two most common types will be the concentric (insight and output shafts are in range) and parallel shaft (insight and output shafts are offset). Single-stage helical gear reducers are typically used for gear ratios up to about 8:1. Where reduced speeds and higher ratios are necessary, double, triple, and quadruple gear reduction stages can be used.
