GEARBOX REDUCERS
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 identifying which gearbox alternative is most beneficial for you.
RIGHT ANGLE REDUCERS
WORM GEAR REDUCER
EP’s worm equipment reducers are designed with a hollow bore and allow for a corner switch with optional dual output. 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 options providing flexibility when incorporating the reducer into item.
RIGHT ANGLE BEVEL GEARBOX
bevel-right-angle-gearbox
The proper angle bevel gearbox combines the top features of our right angle worm and planetary inline reducers. With a good and efficient correct angle configuration, our right angle planetary gearboxes provide a robust solution. The right angle bevel gearbox comes in 18 ratios ranging from 5:1 to 1000:1, and it is back-drivable at all ratios.
INLINE REDUCERS
I-SERIES PLANETARY GEARBOX
i-series-planetary-gearbox

These gearboxes are made to manage varying loads with little backlash. With frame sizes 52cm, 62cm, and 81cm, 12 ratios ranging from 5:1 to 308:1, we’ve a solution to fit your needs. Our 52 frame size is also available with plastic material gears for noise-sensitive applications.
INLINE PLANETARY GEARBOX
inline-planetary-gearbox
Our inline planetary gearbox configurations supply the highest performance and best result torque of most our quickness reducers. These gearboxes are created to manage varying loads with small backlash. Planetary gear reducers operate more quietly than parallel shaft reducers. With 18 ratio choices which range from 5:1 to 1000:1, we’ve a solution to suit your needs.
PARALLEL SHAFT GEARBOX
parallel-shaft-gearbox
Parallel shaft gearboxes will be the best choice for continuous duty applications. Their equipment cluster design provides an effective method for dissipating heat. Parallel shaft gearboxes possess the shortest amount of our inline gear reducer options therefore they work very well in environments with limited space. Our parallel shaft gear reducers offer 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, rate reducers, worm gear reducers and worm drive gearboxes. Gear decrease boxes include a gear arrangement when 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 steel or stainless steel.

While worm gears are similar to a spur equipment, the worm gearboxes are considerably smaller than other gear reduction boxes. A main benefit of worm gear reducers is definitely that they generate an output that is 90° from the input and can be used to transmit higher torque or reduce rotational speed. Frequently, a worm gearbox provides right hand threads; to change the direction of the result, a left-hand thread worm gearbox is required.

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). Output torque ranges from 33,000 in pounds. for the 7” CD EP-70 to 582,900 in lbs 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 are available in four configurations: horizontal, vertical, shafted, and shaft mounted.

These reducers are ideal for water/waste-water gear drive applications such as for example thickeners and clarifiers, which need a vertical down shaft. Other obtainable 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 large torques/slower speeds are needed.

These reducers are also available with a worm reduction gearbox helical primary reduction stage and are termed the HDVM series

Enclosed Gears / Gearboxes
Enclosed gears, also called gearboxes or speed reducers, are open gears within a housing. The housing supports bearings and shafts, keeps in lubricants, and protects the parts from surrounding circumstances. Gearboxes are available in an array of load capacities and acceleration ratios.

The objective of a gearbox is to improve or reduce speed. As a result, torque output will be the inverse of the function. If the enclosed drive can be a swiftness reducer, the torque output will increase; if the drive improves speed, the torque result will reduce. Gear drive selection factors include: shaft orientation, velocity 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 little package. Known as right angle drives, these consist of a cylindrical worm with screw threads and a worm. With a single start worm, the worm gear advances only 1 tooth for every 360-degree convert of the worm. So, whatever 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 units of gears. Power is transmitted from a high-speed pinion to a slower-speed equipment. Helical gears generally operate with their shafts parallel to each other. Both most common types will be the concentric (insight and result shafts are in collection) and parallel shaft (insight and output shafts are offset). Single-stage helical gear reducers are typically used for equipment ratios up to about 8:1. Where reduced speeds and higher ratios are necessary, dual, triple, and quadruple equipment reduction stages may be used.

Cycloidal Disc Speed Reducers
Not the same as conventional gearing because they operate without a high rate pinion or gear teeth, and the elements operate in compression instead of shear. This is due to the design of the cycloidal discs that roll within a ring gear housing, comparable to a planetary style. The primary 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, 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 is driven by a separate NEMA C-face motor.

Seals and Breathers
Seals are used between your gear housing and input and output shafts to retain oil and prevent 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 make use of for high-rate applications, and contain a housing with some bands that limit leakage. A breather can be a connect with a hole that’s mounted in the apparatus housing to permit airflow and relieve internal pressure.

Lubrication
Enclosed gears are usually lubricated with oil. The most common types of oil are rust and oxidation inhibiting, intense pressure, compounded, and synthetic. Other types consist of grease and solid film. Grease can be used for worm, planetary, cycloidal, and hypoidal reducers. Common distribution methods are a splash program and a circulating system
Worm Reduction Gearbox Program:

Worm drives certainly are a compact means of substantially decreasing quickness 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 may be suitable for, especially when the worm drive’s compactness is considered.

Worm drives are used in presses, in rolling mills, in conveying engineering, in mining sector machines, and on rudders. In addition, milling heads and rotary tables are positioned using high-precision duplex worm drives with adjustable backlash.
