GEARBOX REDUCERS
Right angle gearboxes (worm and planetary) are tough and built for 90° turns. Inline reducers (worm reduction gearbox parallel shaft and planetary) are an ideal match for motors with high input speeds, or when gearmotor performance is important. Contact our technical sales staff for help determining which gearbox alternative is best for you.
RIGHT ANGLE REDUCERS
WORM GEAR REDUCER
EP’s worm equipment reducers were created with a hollow bore and allow for a corner switch with optional dual result. 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 choices providing flexibility when incorporating the reducer into item.
RIGHT ANGLE BEVEL GEARBOX
bevel-right-angle-gearbox
The right angle bevel gearbox combines the features of our right 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 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 small planetary gearbox configurations supply the smallest footprint and quietest operation of our acceleration reducers. These gearboxes are designed to deal with varying loads with small backlash. With framework sizes 52cm, 62cm, and 81cm, 12 ratios ranging from 5:1 to 308:1, we’ve a solution to suit your needs. Our 52 frame size can be 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 output torque of all our quickness reducers. These gearboxes are designed 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 are the best choice for continuous duty applications. Their equipment cluster design provides a highly effective method for dissipating warmth. Parallel shaft gearboxes have the shortest amount of our inline gear reducer options so they work very well in conditions 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, quickness reducers, worm gear reducers and worm drive gearboxes. Gear decrease boxes feature a gear arrangement when a gear in the kind of a screw, also known as a worm, meshes with a worm gear. These gears are typically created 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 usually that they create an output that’s 90° from the insight and can be utilized to transmit higher torque or reduce rotational speed. Most often, a worm gearbox provides right hand threads; to improve the path of the result, a left-hands thread worm gearbox is required.

GEAR RATIO 10:1
Ever-Power EP series triple-reduction worm gear quickness 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). Result torque ranges from 33,000 in pounds. 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 installed.
These reducers are perfect for water/waste-water gear drive applications such as thickeners and clarifiers, which need a vertical straight down shaft. Other available 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 huge torques/slower 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 referred to as gearboxes or speed reducers, are open gears within a housing. The housing supports bearings and shafts, holds in lubricants, and protects the components from surrounding circumstances. Gearboxes can be found in an array of load capacities and speed ratios.
The purpose of a gearbox is to improve or reduce speed. As a result, torque output would be the inverse of the function. If the enclosed drive is a swiftness reducer, the torque result will increase; if the drive raises speed, the torque output will reduce. Gear drive selection elements include: shaft orientation, swiftness 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 rate reducer can achieve up to 100:1 reduction ratio in a little 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 1 tooth for every 360-degree convert of the worm. So, whatever the worm’s size, the apparatus ratio is the ‘size of the worm equipment to 1′. Higher decrease ratios could be created by using double and triple decrease ratios.
Helical Gear Speed Reducers
Provide high-efficiency speed decrease through 1, 2, 3, or 4 models of gears. Power is usually transmitted from a high-quickness pinion to a slower-speed gear. Helical gears generally 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 reduced speeds and higher ratios are necessary, double, triple, and quadruple gear reduction stages can be used.
Cycloidal Disc Speed Reducers
Not the same as conventional gearing because they operate with out a high quickness pinion or gear teeth, and the parts operate in compression instead of shear. This is because of the style of the cycloidal discs that roll within a ring gear housing, comparable to a planetary style. The main components will be the eccentric cam, the internally flanged result 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, 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 electric motor. 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 output shafts to retain oil and block dirt. The mostly used type, the radial lip seal, contains a metallic casing that fits into the casing bore and an elastomeric sealing lip that presses on the shaft. Labyrinth seals are use for high-rate applications, and contain a housing with a series of rings that limit leakage. A breather is definitely a connect with a hole that is mounted in the apparatus housing allowing airflow and relieve internal pressure.
Lubrication
Enclosed gears are usually lubricated with oil. The most typical types of oil are rust and oxidation inhibiting, severe pressure, compounded, and synthetic. Other types consist of 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 Application:
Worm drives are a compact means of substantially decreasing velocity and increasing torque. Little electric motors are generally high-speed and low-torque; the addition of a worm drive escalates the range of applications that it might be suitable for, particularly when the worm drive’s compactness is known as.
Worm drives are used in presses, in rolling mills, in conveying engineering, in mining market machines, and on rudders. Furthermore, milling heads and rotary tables are positioned using high-precision duplex worm drives with adjustable backlash.
