GEARBOX REDUCERS
Correct angle gearboxes (worm and planetary) are tough and built for 90° turns. Inline reducers (parallel shaft and planetary) are an ideal match for motors with high insight speeds, or when gearmotor performance is important. Contact our technical sales personnel for help identifying which gearbox remedy is best for you.
RIGHT ANGLE REDUCERS
WORM GEAR REDUCER
EP’s worm gear reducers were created with a hollow bore and allow for a corner turn with optional dual output. The reducers can be found 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 options providing flexibility when incorporating the reducer into product.
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 correct angle configuration, our right angle planetary gearboxes provide a robust solution. The proper angle bevel gearbox comes 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 operation of our speed reducers. These gearboxes are made to deal with 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 fit your needs. Our 52 frame size is also available with plastic-type material gears for noise-delicate applications.
INLINE PLANETARY GEARBOX
inline-planetary-gearbox
Our inline planetary gearbox configurations provide the highest effectiveness and best result torque of most our speed reducers. These gearboxes are made to deal with varying loads with little backlash. Planetary gear reducers operate more quietly than parallel shaft reducers. With 18 ratio options ranging from 5:1 to 1000:1, we’ve a solution to fit your needs.
PARALLEL SHAFT GEARBOX
parallel-shaft-gearbox
Parallel shaft gearboxes are the top choice for continuous duty applications. Their gear cluster design provides a highly effective method for dissipating heat. Parallel shaft gearboxes possess the shortest amount of our inline gear reducer options so they work very well in conditions with limited space. Our parallel shaft equipment 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, acceleration reducers, worm gear reducers and worm drive gearboxes. Gear reduction boxes feature a gear arrangement when a equipment in the kind of a screw, also called a worm, meshes with a worm gear. These gears are typically made from bronze and the worms are metal or stainless steel.
While worm gears act like a spur equipment, the worm gearboxes are significantly smaller than other equipment reduction boxes. A major benefit of worm equipment reducers is that they create an output that’s 90° from the insight and can be used to transmit higher torque or decrease rotational speed. Most often, a worm gearbox has 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 acceleration reducers are available in ratios from 5000:1 to 175,000:1 and center distances from 7” to 20” (larger sizes on request). Output torque ranges from 33,000 in lbs. for the 7” CD EP-70 to 582,900 in pounds 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 equipment drive applications such as thickeners and clarifiers, which need a vertical straight 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 other process or materials handling systems where large torques/gradual speeds are needed.
These reducers are also obtainable with a helical major reduction stage and so are termed the HDVM series
Enclosed Gears / Gearboxes
Enclosed gears, also known as gearboxes or quickness reducers, are open gears within a housing. The housing facilitates bearings and shafts, holds in lubricants, and protects the components from surrounding conditions. Gearboxes can be found in an array of load capacities and acceleration 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 a rate reducer, the torque output increase; if the drive improves speed, the torque output will reduce. Gear drive selection factors 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 speed reducer can achieve up to a 100:1 reduction ratio in a small package. Referred to as right position drives, these consist of a cylindrical worm with screw threads and a worm. With a single start worm, the worm equipment advances only one tooth for each 360-degree switch of the worm. So, whatever the worm’s size, the gear 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 sets of gears. Power is usually transmitted from a high-quickness pinion to a slower-speed gear. Helical gears usually operate with their shafts parallel to one another. The two most common types are the concentric (input and output shafts are in line) and parallel shaft (input and result shafts are offset). Single-stage helical gear reducers are usually used for equipment ratios up to about 8:1. Where reduce speeds and higher ratios are required, double, triple, and quadruple gear reduction stages can be used.
Cycloidal Disc Speed Reducers
Different from conventional gearing worm reduction gearbox because they operate with out a high velocity pinion or gear teeth, and the elements operate in compression instead of shear. This is due to the style of the cycloidal discs that roll within a band gear housing, similar to a planetary style. The main components will be the eccentric cam, the internally flanged output shaft, the discs, and the ring gear housing.
Three Mounting Options
(L-R) Base Mounted, Shaft-Mounted, Gearmotor
(L-R) Base-Mounted, Shaft-Mounted, Gearmotor
Base-mounted reducers, which have feet for bolting, are the most common.
Shaft-mounted reducers have a hollow output shaft that slips over the driven shaft.
A gearmotor combines a specific gearset with a engine. A motorized reducer resembles a gearmotor except that it’s driven by another NEMA C-face motor.
Seals and Breathers
Seals are used between your gear housing and insight and output shafts to retain oil and prevent dirt. The mostly utilized type, the radial lip seal, includes a metal casing that fits in to the casing bore and an elastomeric sealing lip that presses on the shaft. Labyrinth seals are use for high-acceleration applications, and contain a housing with a series of bands that limit leakage. A breather is definitely a plug with a hole that is mounted in the gear housing allowing airflow and relieve internal pressure.
Lubrication
Enclosed gears are generally lubricated with oil. The most common types of essential oil are rust and oxidation inhibiting, intense pressure, compounded, and synthetic. Other types include grease and solid film. Grease can be used for worm, planetary, cycloidal, and hypoidal reducers. Common distribution methods are a splash system and a circulating system
Worm Reduction Gearbox App:
Worm drives are a compact method of substantially decreasing acceleration and increasing torque. Little electric motors are generally high-speed and low-torque; the addition of a worm drive escalates the selection of applications that it might 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 market machines, and on rudders. In addition, milling heads and rotary tables sit using high-precision duplex worm drives with adjustable backlash.
