GEARBOX REDUCERS
Right angle gearboxes (worm and planetary) are rugged and built for 90° turns. Inline reducers (parallel shaft and planetary) are an ideal match for motors with high input speeds, or when gearmotor performance is important. Get in touch with our technical sales personnel for help determining which gearbox option 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 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 choices providing flexibility when incorporating the reducer into item.
RIGHT ANGLE BEVEL GEARBOX
bevel-right-angle-gearbox
The proper angle bevel gearbox combines the features of our right 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, 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 provide the smallest footprint and quietest procedure of our quickness reducers. These gearboxes are made to deal with varying loads with little backlash. With body sizes 52cm, 62cm, and 81cm, 12 ratios ranging from 5:1 to 308:1, we have a solution to suit 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 effectiveness and best result torque of all our acceleration reducers. These gearboxes are made to manage varying loads with small backlash. Planetary equipment reducers operate more quietly than parallel shaft reducers. With 18 ratio options ranging 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 constant duty applications. Their gear cluster design provides an effective method for dissipating warmth. Parallel shaft gearboxes have the shortest length of our inline equipment reducer options therefore they work well in conditions with limited space. Our parallel shaft equipment reducers offer an affordable drop-in replacement solution for most small parallel shaft gearmotors.
Wormwheel gearboxes go by several names, including 90-degree gearboxes, right angle gearboxes, swiftness reducers, worm equipment reducers and worm drive gearboxes. Gear decrease boxes include a gear arrangement in which a gear in the type of a screw, also known as a worm, meshes with a worm gear. These gears are usually made from bronze and the worms are steel or stainless steel.

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

Ever-Power EP series triple-reduction worm gear rate reducers are available 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 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 mounted.

These reducers are ideal for water/waste-water tools drive applications such as thickeners and clarifiers, which require a vertical 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 additional process or materials handling systems where huge torques/slower speeds are needed.

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

Enclosed Gears / Gearboxes
Enclosed gears, also called gearboxes or rate reducers, are open gears contained in a housing. The housing facilitates bearings and shafts, retains in lubricants, and protects the components from surrounding circumstances. Gearboxes are available in a wide variety of load capacities and speed ratios.

The purpose of a gearbox is to improve or reduce speed. Consequently, torque output will be the inverse of the function. If the enclosed drive is usually a acceleration reducer, the torque result will increase; if the drive boosts speed, the torque result will decrease. Gear drive selection elements include: shaft orientation, velocity 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 quickness reducer can achieve up to a 100:1 decrease ratio in a small package. Referred to as right angle drives, these contain a cylindrical worm with screw threads and a worm. With an individual start worm, the worm gear advances only one tooth for each 360-degree switch of the worm. So, whatever the worm’s size, the apparatus ratio may be the ‘size of the worm gear to 1′. Higher reduction ratios could be created by using double and triple decrease ratios.

Helical Gear Speed Reducers
Provide high-efficiency speed reduction through 1, 2, 3, or 4 models of gears. Power can be transmitted from a high-swiftness pinion to a slower-speed equipment. Helical gears usually operate with their shafts parallel to one another. The two most common types will be the concentric (insight and result shafts are in line) and parallel shaft (insight and result 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 needed, double, triple, and quadruple equipment reduction stages can be used.
