GEARBOX REDUCERS
Right angle gearboxes (worm and planetary) are rugged 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 personnel for help determining which gearbox alternative is most beneficial for you.
RIGHT ANGLE REDUCERS
WORM GEAR REDUCER
EP’s worm equipment reducers are designed with a hollow bore and allow for a corner convert with optional dual output. The reducers come 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 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 provide a robust solution. The right angle bevel gearbox comes in 18 ratios ranging 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 little planetary gearbox configurations supply the smallest footprint and quietest operation of our velocity reducers. These gearboxes are made to deal with varying loads with small backlash. With frame sizes 52cm, 62cm, and 81cm, 12 ratios ranging from 5:1 to 308:1, we’ve 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 supply the highest performance and best result torque of most our quickness reducers. These gearboxes are created to deal with varying loads with small backlash. Planetary gear reducers operate more quietly than parallel shaft reducers. With 18 ratio choices which range from 5:1 to 1000:1, we have a solution to suit your needs.
PARALLEL SHAFT GEARBOX
parallel-shaft-gearbox
Parallel shaft gearboxes will be the best choice for continuous duty applications. Their equipment cluster design provides an effective method for dissipating warmth. Parallel shaft gearboxes have the shortest amount of our inline gear reducer options so they work very well in environments with limited space. Our parallel shaft gear reducers offer an affordable drop-in substitute solution for most little parallel shaft gearmotors.
Wormwheel gearboxes pass several names, including 90-degree gearboxes, right angle gearboxes, rate reducers, worm equipment reducers and worm drive gearboxes. Gear reduction boxes include a gear arrangement in which a equipment in the kind of a screw, also known as a worm, meshes with a worm equipment. These gears are usually created from bronze and the worms are steel or stainless steel.

While worm gears are similar to a spur equipment, the worm gearboxes are significantly smaller than other gear reduction boxes. A major benefit of worm gear reducers can be that they produce an output that is 90° from the input and can be used to transmit higher torque or decrease rotational speed. Most often, a worm gearbox provides right hand threads; to change the path of the output, a left-hand thread worm gearbox is necessary.

Ever-Power EP series triple-reduction worm gear speed 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). Output torque ranges from 33,000 in pounds. 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 are available in four configurations: horizontal, vertical, shafted, and shaft installed.

These reducers are ideal for water/waste-water gear drive applications such as thickeners and clarifiers, which need a vertical down shaft. Other offered configurations also make Ever-Power triple decrease reducers perfect for use on mixers, elevators, solar power 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 available with a helical primary reduction stage and are termed the HDVM series

Enclosed Gears / Gearboxes
Enclosed gears, also called gearboxes or rate reducers, are open gears within a housing. The housing facilitates bearings and shafts, retains in lubricants, and protects the elements from surrounding conditions. Gearboxes are available in an array of load capacities and swiftness ratios.

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

Basic Types of Gearboxes

Worm Gear Speed Reducers
A single reduction velocity reducer can achieve up to a 100:1 reduction ratio in a little package. Known as right angle drives, these consist of a cylindrical worm with screw threads and a worm. With an individual begin worm, the worm gear advances only 1 tooth for every 360-degree turn of the worm. So, whatever the worm’s size, the gear ratio is the ‘size of the worm equipment to 1′. Higher reduction ratios can be created through the use of double and triple decrease ratios.

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