Right angle gearboxes (worm and planetary) are tough and built for 90° turns. Inline reducers (parallel shaft and planetary) are a perfect 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 alternative is most beneficial for you.
RIGHT ANGLE REDUCERS
WORM GEAR REDUCER
EP’s worm equipment reducers were created with a hollow bore and allow for a corner turn 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 right angle gearboxes are designed with five mounting choices providing flexibility when incorporating the reducer into item.
RIGHT ANGLE BEVEL GEARBOX
The proper angle bevel gearbox combines the top features of our correct angle worm and planetary inline reducers. With a good and efficient right angle configuration, our right angle planetary gearboxes offer 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.
I-SERIES PLANETARY GEARBOX
Our I-Series little planetary gearbox configurations provide the smallest footprint and quietest operation of our acceleration reducers. These gearboxes are created to manage 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 suit your needs. Our 52 frame size can be available with plastic-type gears for noise-sensitive applications.
INLINE PLANETARY GEARBOX
Our inline planetary gearbox configurations provide the highest efficiency and best output torque of all our quickness reducers. These gearboxes are created to deal with varying loads with little backlash. Planetary equipment 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 fit your needs.
PARALLEL SHAFT GEARBOX
Parallel shaft gearboxes will be the top choice for constant duty applications. Their equipment cluster design provides an effective method for dissipating heat. Parallel shaft gearboxes possess the shortest length of our inline gear reducer options therefore they work well in environments with limited space. Our parallel shaft gear reducers provide an affordable drop-in substitute solution for most little parallel shaft gearmotors.
Wormwheel gearboxes go by several names, including 90-degree gearboxes, right position gearboxes, swiftness reducers, worm gear reducers and worm drive gearboxes. Gear decrease boxes feature a gear arrangement when a equipment 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 act like a spur gear, the worm gearboxes are considerably smaller than other equipment reduction boxes. A major benefit of worm equipment reducers is certainly that they produce an output that’s 90° from the insight and can be utilized to transmit higher torque or reduce rotational speed. Frequently, a worm gearbox offers right hand threads; to improve the direction of the result, a left-hands thread worm gearbox is necessary.

Ever-Power EP series triple-reduction worm gear quickness 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 lbs. 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 perfect for water/waste-water gear drive applications such as for example thickeners and clarifiers, which require a vertical straight down shaft. Other offered 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 materials handling systems where huge torques/slow speeds are needed.
These reducers are also obtainable with a helical main reduction stage and so are termed the HDVM series
Enclosed Gears / Gearboxes
Enclosed gears, also called gearboxes or speed reducers, are open gears contained in a housing. The casing facilitates bearings and shafts, retains in lubricants, and protects the elements from surrounding conditions. Gearboxes can be found in an array of load capacities and swiftness ratios.
The objective of a gearbox is to increase or reduce speed. As a result, torque output would be the inverse of the function. If the enclosed drive is certainly a rate reducer, the torque result increase; if the drive increases speed, the torque result will reduce. Gear drive selection elements include: shaft orientation, swiftness ratio, design type, character of load, gear ranking, 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 a 100:1 reduction ratio in a small package. Known as right position drives, these contain a cylindrical worm with screw threads and a worm. With an individual begin worm, the worm gear advances only one tooth for every 360-degree convert of the worm. So, whatever the worm’s size, the apparatus ratio may be the ‘size of the worm equipment to 1′. Higher decrease ratios could be created through the use of double and triple reduction ratios.
Helical Gear Speed Reducers
Provide high-efficiency speed decrease through 1, 2, 3, or 4 sets of gears. Power is usually 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 (input and output shafts are in series) and parallel shaft (input and result 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, dual, triple, and quadruple gear reduction stages may be used.
Cycloidal Disc Speed Reducers
Different from conventional gearing because they operate with out a high swiftness pinion or equipment teeth, and the components operate in compression rather than shear. This is because of the style of the cycloidal discs that roll within a ring gear housing, similar to a planetary style. The primary components are the eccentric cam, the internally flanged output shaft, the discs, and the ring gear housing.
Three Mounting Options
(L-R) Bottom Mounted, Shaft-Mounted, Gearmotor
(L-R) Base-Mounted, Shaft-Mounted, Gearmotor
Base-mounted reducers, that have feet for bolting, will be the most common.
Shaft-mounted reducers possess a hollow output shaft that slips more than the driven shaft.
A gearmotor combines a specific gearset with a engine. A motorized reducer resembles a gearmotor except that it’s driven by a separate NEMA C-face motor.
Seals and Breathers
Seals are used between your gear housing and insight and result shafts to retain essential oil and prevent dirt. The mostly used type, the radial lip seal, includes a metal casing that fits into the casing bore and an elastomeric sealing lip that presses on the shaft. Labyrinth seals are make use of for high-speed applications, and contain a housing with some bands that limit worm reduction gearbox leakage. A breather is a connect with a hole that’s mounted in the apparatus housing allowing airflow and relieve internal pressure.
Enclosed gears are generally lubricated with oil. The most common types of oil are rust and oxidation inhibiting, intense pressure, compounded, and synthetic. Other types include grease and solid film. Grease can be utilized for worm, planetary, cycloidal, and hypoidal reducers. Common distribution methods are a splash program and a circulating system
Worm Reduction Gearbox App:
Worm drives certainly are a compact method of substantially decreasing quickness and increasing torque. Small electric motors are generally high-speed and low-torque; the addition of a worm drive increases the range of applications that it may be suitable for, particularly when the worm drive’s compactness is known as.
Worm drives are found in presses, in rolling mills, in conveying engineering, in mining industry machines, and on rudders. Furthermore, milling heads and rotary tables sit using high-precision duplex worm drives with adjustable backlash.
