GEARBOX REDUCERS
Right angle gearboxes (worm and planetary) are durable 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. Contact 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 allow for a corner convert with optional dual result. The reducers come 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 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 good and efficient right angle configuration, our right angle planetary gearboxes offer a robust solution. The right angle bevel gearbox will come 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 acceleration reducers. These gearboxes are created to handle varying loads with small backlash. With framework sizes 52cm, 62cm, and 81cm, 12 ratios which range from 5:1 to 308:1, we’ve a solution to suit your needs. Our 52 frame size can be available with plastic material gears for noise-delicate applications.
INLINE PLANETARY GEARBOX
inline-planetary-gearbox
Our inline planetary gearbox configurations provide the highest efficiency and best result torque of most our velocity reducers. These gearboxes are created to deal with varying loads with little backlash. Planetary gear 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-gearbox
Parallel shaft gearboxes will be the top choice for continuous duty applications. Their equipment cluster design provides an effective method for dissipating high temperature. Parallel shaft gearboxes have the shortest amount of our inline gear reducer options therefore they work very well in conditions with limited space. Our parallel shaft gear reducers offer an affordable drop-in replacement solution for most little parallel shaft worm reduction gearbox gearmotors.
Wormwheel gearboxes go by several names, including 90-degree gearboxes, right angle gearboxes, velocity reducers, worm gear reducers and worm drive gearboxes. Gear decrease boxes feature a gear arrangement in which a gear in the type of a screw, also referred to as a worm, meshes with a worm equipment. These gears are typically made from bronze and the worms are steel or stainless steel.

While worm gears are similar to a spur gear, the worm gearboxes are considerably smaller than other gear reduction boxes. A primary benefit of worm equipment reducers is certainly that they generate an output that is 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 direction of the result, a left-hand thread worm gearbox is necessary.

Ever-Power EP series triple-reduction worm gear velocity reducers can be found 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 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 ideal for water/waste-water tools drive applications such as thickeners and clarifiers, which need a vertical straight 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 additional process or components handling systems where huge torques/slow speeds are needed.

These reducers are also offered with a helical main reduction stage and so are termed the HDVM series

Enclosed Gears / Gearboxes
Enclosed gears, also known as gearboxes or rate reducers, are open gears within a housing. The casing facilitates bearings and shafts, keeps in lubricants, and protects the components from surrounding conditions. Gearboxes are available in a wide variety of load capacities and speed ratios.

The objective of a gearbox is to increase or reduce speed. Consequently, torque output will be the inverse of the function. If the enclosed drive is certainly a velocity reducer, the torque output will increase; if the drive increases speed, the torque result will decrease. Gear drive selection elements include: shaft orientation, rate ratio, design type, nature of load, gear rating, 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 a 100:1 reduction ratio in a little package. Known as right angle drives, these consist of a cylindrical worm with screw threads and a worm. With an individual start worm, the worm equipment advances only one tooth for every 360-degree convert of the worm. So, regardless of the worm’s size, the gear ratio is the ‘size of the worm equipment to 1′. Higher reduction ratios can be created by using double and triple decrease ratios.

Helical Gear Speed Reducers
Provide high-efficiency speed reduction through 1, 2, 3, or 4 pieces of gears. Power is usually transmitted from a high-swiftness pinion to a slower-speed equipment. Helical gears generally operate with their shafts parallel to each other. The two most common types are the concentric (insight and result shafts are in line) and parallel shaft (input and output shafts are offset). Single-stage helical equipment reducers are typically used for gear ratios up to about 8:1. Where decrease speeds and higher ratios are required, double, triple, and quadruple equipment reduction stages can be used.

Cycloidal Disc Speed Reducers
Not the same as conventional gearing because they operate with out a high acceleration pinion or equipment teeth, and the parts operate in compression rather than shear. This is due to the style of the cycloidal discs that roll within a ring gear housing, similar to a planetary style. The primary components will be the eccentric cam, the internally flanged output shaft, the discs, and the ring gear casing.

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, will be the most common.

Shaft-mounted reducers have 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 another NEMA C-face motor.

Seals and Breathers
Seals are used between your gear housing and input and result shafts to retain oil and block dirt. The mostly used type, the radial lip seal, consists of 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 bands that limit leakage. A breather is definitely a connect with a hole that’s mounted in the gear 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, 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 methods are a splash program and a circulating system
Worm Reduction Gearbox Software:

Worm drives are a compact means of substantially decreasing swiftness 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 could 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 sector machines, and on rudders. Furthermore, milling heads and rotary tables sit using high-precision duplex worm drives with adjustable backlash.
