GEARBOX REDUCERS
Right angle gearboxes (worm and planetary) are durable and built for 90° turns. Inline reducers (parallel shaft and planetary) are a perfect match for motors with high insight speeds, or when gearmotor effectiveness is important. Contact our technical sales personnel for help determining 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 invite 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 correct angle gearboxes were created with five mounting options providing versatility when incorporating the reducer into product.
RIGHT ANGLE BEVEL GEARBOX
bevel-right-angle-gearbox
The right angle bevel gearbox combines the top features of our right angle worm and planetary inline reducers. With a good and efficient right angle configuration, our correct angle planetary gearboxes offer a robust solution. The proper 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 provide the smallest footprint and quietest procedure of our velocity reducers. These gearboxes are made 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 have a solution to fit your needs. Our 52 frame size is also available with plastic-type 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 all our acceleration reducers. These gearboxes are made 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 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 a highly effective method for dissipating high temperature. Parallel shaft gearboxes have the shortest length of our inline equipment reducer options so they work very well in conditions with limited space. Our parallel shaft gear reducers offer an affordable drop-in substitute solution for most small 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 feature a gear arrangement when a equipment in the form of a screw, also called a worm, meshes with a worm equipment. These gears are typically created from bronze and the worms are steel or stainless steel.

While worm gears act like a spur equipment, the worm gearboxes are significantly smaller than other equipment reduction boxes. A primary benefit of worm equipment reducers is usually that they produce an output that’s 90° from the input and can be utilized to transmit higher torque or reduce rotational speed. Most often, a worm gearbox offers 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 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 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 installed.

These reducers are ideal for water/waste-water gear drive applications such as for example thickeners and clarifiers, which require a vertical down shaft. Other obtainable configurations also make Ever-Power triple reduction 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/slower 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 called gearboxes or swiftness reducers, are open gears contained in a housing. The casing supports bearings and shafts, keeps in lubricants, and protects the components from surrounding circumstances. Gearboxes are available in a wide selection of load capacities and rate ratios.

The objective of a gearbox is to improve or reduce speed. Because of this, torque output would be the inverse of the function. If the enclosed drive is usually a acceleration reducer, the torque result increase; if the drive improves speed, the torque output will decrease. Gear drive selection elements include: shaft orientation, swiftness ratio, design type, nature of load, gear ranking, environment, mounting position, working temperature range, and lubrication.

Basic Types of Gearboxes

Worm Gear Speed Reducers
A single reduction speed reducer can achieve up to 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 start worm, the worm gear advances only 1 tooth for every 360-degree change of the worm. So, whatever the worm’s size, the gear ratio is the ‘size of the worm gear to 1′. Higher decrease ratios can be created through the use of double and triple decrease ratios.

Helical Gear Speed Reducers
Provide high-efficiency speed decrease through 1, 2, 3, or 4 units of gears. Power can be transmitted from a high-acceleration pinion to a slower-speed gear. 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 series) and parallel shaft (insight and output shafts are offset). Single-stage helical equipment reducers are typically used for equipment ratios up to about 8:1. Where lower speeds and higher ratios are needed, dual, triple, and quadruple gear reduction stages can be used.

Cycloidal Disc Speed Reducers
Different from conventional gearing because they operate with out a high acceleration 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 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 casing.

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, are the most common.

Shaft-mounted reducers possess a hollow output shaft that slips more than the driven shaft.

A gearmotor combines an enclosed 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 insight and result shafts to retain essential oil and prevent dirt. The most commonly utilized 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 make use of for high-swiftness applications, and contain a housing with a series of bands that limit leakage. A breather is usually a connect with a hole that’s mounted in the apparatus housing to permit airflow and relieve inner 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 styles consist of grease and solid film. Grease can be used for worm, planetary, cycloidal, and hypoidal reducers. Common distribution strategies are a splash system and a circulating system
Worm Reduction Gearbox Software:

Worm drives certainly are a compact means of substantially decreasing swiftness and increasing torque. Small electric motors are usually high-speed and low-torque; the addition of a worm drive increases the selection of applications that it could 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 devices, and on rudders. In addition, milling heads and rotary tables are positioned using high-precision duplex worm drives with adjustable backlash.
