Correct 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 insight speeds, or when gearmotor efficiency is important. Get in touch with our technical sales personnel for help identifying which gearbox alternative is most beneficial for you.
RIGHT ANGLE REDUCERS
WORM GEAR REDUCER
EP’s worm gear reducers were created with a hollow bore and invite for a worm reduction gearbox corner convert 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 correct angle gearboxes are designed with five mounting choices providing versatility when incorporating the reducer into item.
RIGHT ANGLE BEVEL GEARBOX
The proper angle bevel gearbox combines the features of our right angle worm and planetary inline reducers. With a solid 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 rate reducers. These gearboxes are designed to deal with varying loads with little backlash. With body sizes 52cm, 62cm, and 81cm, 12 ratios which range from 5:1 to 308:1, we have a solution to fit your needs. Our 52 frame size can be available with plastic gears for noise-sensitive applications.
INLINE PLANETARY GEARBOX
Our inline planetary gearbox configurations supply the highest performance and best output torque of all our velocity reducers. These gearboxes are created 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 fit your needs.
PARALLEL SHAFT GEARBOX
Parallel shaft gearboxes are the best choice for continuous duty applications. Their gear cluster design provides an effective method for dissipating temperature. Parallel shaft gearboxes possess the shortest length of our inline gear reducer options therefore they work very well in conditions with limited space. Our parallel shaft equipment reducers provide an affordable drop-in alternative solution for most little parallel shaft gearmotors.
Wormwheel gearboxes pass several names, including 90-degree gearboxes, right position gearboxes, velocity reducers, worm gear reducers and worm drive gearboxes. Gear decrease boxes include a gear arrangement in which a equipment in the kind of a screw, also known as a worm, meshes with a worm equipment. These gears are usually created 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 gear reduction boxes. A main benefit of worm gear reducers is usually that they produce an output that’s 90° from the insight and can be utilized to transmit higher torque or decrease rotational speed. Most often, a worm gearbox offers right hand threads; to change the path of the result, a left-hands thread worm gearbox is necessary.

GEAR RATIO 10:1
Ever-Power EP series triple-reduction worm gear swiftness reducers can be found in ratios from 5000:1 to 175,000:1 and middle distances from 7” to 20” (larger sizes on request). Output torque ranges from 33,000 in pounds. 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 perfect for water/waste-water apparatus drive applications such as for example thickeners and clarifiers, which require a vertical down shaft. Other obtainable configurations also make Ever-Power triple decrease reducers perfect for use on mixers, elevators, solar panels, astronomical telescopes, indexing tables, hoists, conveyors, or various other process or components handling systems where large torques/sluggish speeds are needed.
These reducers are also available with a helical principal 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 within a housing. The casing facilitates bearings and shafts, retains in lubricants, and protects the components from surrounding circumstances. Gearboxes can be found in an array of load capacities and swiftness ratios.
The objective 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 usually a velocity reducer, the torque result increase; if the drive increases speed, the torque result will reduce. Gear drive selection elements include: shaft orientation, speed 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 acceleration reducer can achieve up to a 100:1 reduction ratio in a small package. Known as right angle drives, these consist of a cylindrical worm with screw threads and a worm. With a single begin worm, the worm gear advances only 1 tooth for each 360-degree switch of the worm. So, regardless of the worm’s size, the apparatus ratio is the ‘size of the worm gear to 1′. Higher reduction ratios can be created by using double and triple decrease ratios.
Helical Gear Speed Reducers
Provide high-efficiency speed decrease through 1, 2, 3, or 4 pieces of gears. Power is usually transmitted from a high-velocity pinion to a slower-speed equipment. Helical gears generally operate with their shafts parallel to one another. The two most common types are the concentric (input and output shafts are in range) and parallel shaft (insight and result shafts are offset). Single-stage helical gear reducers are typically used for gear ratios up to about 8:1. Where lower speeds and higher ratios are required, dual, triple, and quadruple equipment reduction stages may be used.
Cycloidal Disc Speed Reducers
Different from conventional gearing because they operate with out a high acceleration pinion or equipment teeth, and the components operate in compression rather than shear. This is because of the design of the cycloidal discs that roll within a band gear housing, comparable to a planetary design. 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) 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 engine. A motorized reducer resembles a gearmotor except that it is driven by another NEMA C-face motor.
Seals and Breathers
Seals are used between your gear housing and input and result shafts to retain oil and prevent dirt. The mostly used type, the radial lip seal, consists of a metal casing that fits in to the housing bore and an elastomeric sealing lip that presses on the shaft. Labyrinth seals are use for high-swiftness applications, and consist of a housing with some bands that limit leakage. A breather can be a connect with a hole that’s mounted in the gear housing allowing airflow and relieve inner pressure.
Enclosed gears are usually lubricated with oil. The most common types of essential oil are rust and oxidation inhibiting, intense pressure, compounded, and synthetic. Other styles include grease and solid film. Grease can be utilized for worm, planetary, cycloidal, and hypoidal reducers. Common distribution strategies are a splash program and a circulating system
Worm Reduction Gearbox Program:
Worm drives are a compact means of substantially decreasing rate 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, specially 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. In addition, milling heads and rotary tables are positioned using high-precision duplex worm drives with adjustable backlash.
