GEARBOX REDUCERS
Correct 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 input speeds, or when gearmotor effectiveness is important. Get in touch with our technical sales staff for help determining which gearbox solution is most beneficial for you.
RIGHT ANGLE REDUCERS
WORM GEAR REDUCER
EP’s worm equipment reducers were created with a hollow bore and invite for a corner switch with optional dual output. 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 item.
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 correct angle planetary gearboxes provide a robust solution. The right angle bevel gearbox will come 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 little planetary gearbox configurations supply the smallest footprint and quietest procedure of our acceleration 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’ve a solution to fit your needs. Our 52 frame size can be available with plastic material 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 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 have a solution to fit 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 warmth. Parallel shaft gearboxes have the shortest length of our inline equipment reducer options so they work 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 position gearboxes, swiftness reducers, worm equipment reducers and worm drive gearboxes. Gear decrease 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 are similar to a spur gear, the worm gearboxes are considerably smaller than other equipment reduction boxes. A primary benefit of worm equipment reducers is certainly that they produce an output that is 90° from the insight and can be utilized to transmit higher torque or decrease rotational speed. Most often, a worm gearbox provides right hand threads; to change the direction of the result, a left-hands thread worm gearbox is necessary.

Ever-Power EP series triple-reduction worm gear rate reducers can be found in ratios from 5000:1 to 175,000:1 and middle 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 can be found in four configurations: horizontal, vertical, shafted, and shaft mounted.

These reducers are ideal for water/waste-water gear drive applications such as thickeners and clarifiers, which require 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 various other process or components handling systems where large torques/slow speeds are needed.

These reducers are also available with a helical primary reduction stage and so are termed the HDVM series

Enclosed Gears / Gearboxes
Enclosed gears, also referred to as gearboxes or swiftness reducers, are open gears contained in a housing. The housing supports bearings and shafts, keeps in lubricants, and protects the components from surrounding conditions. Gearboxes are available in a wide variety of load capacities and speed ratios.

The purpose of a gearbox is to improve or reduce speed. Because of this, torque output will be the inverse of the function. If the enclosed drive is definitely a swiftness reducer, the torque output increase; if the drive increases speed, the torque result will decrease. Gear drive selection elements include: shaft orientation, speed 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 velocity reducer can achieve up to 100:1 reduction ratio in a little package. Referred to as right position drives, these contain 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 turn of the worm. So, regardless of the worm’s size, the apparatus ratio may be the ‘size of the worm gear to 1′. Higher reduction ratios could 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 units of gears. Power is usually transmitted from a high-velocity pinion to a slower-speed gear. Helical gears usually operate with their shafts parallel to each other. The two most common types will be the concentric (input and output shafts are in collection) and parallel shaft (input and output shafts are offset). Single-stage helical gear reducers are usually used for gear ratios up to about 8:1. Where decrease speeds and higher ratios are necessary, double, triple, and quadruple gear reduction stages may be used.
