GEARBOX REDUCERS
Correct 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 insight speeds, or when gearmotor performance is important. Get in touch with our technical sales personnel for help determining which gearbox remedy is most beneficial for you.
RIGHT ANGLE REDUCERS
WORM GEAR REDUCER
EP’s worm equipment reducers were created with a hollow bore and invite for a 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 right angle gearboxes were created with five mounting choices providing flexibility when incorporating the reducer into item.
RIGHT ANGLE BEVEL GEARBOX

Our 52 frame size can be available with plastic material gears for noise-sensitive applications.
INLINE PLANETARY GEARBOX
inline-planetary-gearbox
Our inline planetary gearbox configurations provide the highest effectiveness and best result torque of all our rate reducers. These gearboxes are designed 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-gearbox
Parallel shaft gearboxes are the best choice for continuous duty applications. Their gear cluster design provides an effective method for dissipating heat. Parallel shaft gearboxes have the shortest length of our inline equipment reducer options therefore they work well in conditions with limited space. Our parallel shaft equipment reducers offer an affordable drop-in replacement solution for most small parallel shaft gearmotors.
Wormwheel gearboxes go by several names, including 90-degree gearboxes, right angle gearboxes, acceleration reducers, worm equipment reducers and worm drive gearboxes. Gear decrease boxes feature a gear arrangement in which a gear in the type of a screw, also known as a worm, meshes with a worm gear. These gears are typically made 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 equipment reducers is usually that they create an output that is 90° from the insight and can be used to transmit higher torque or decrease rotational speed. Most often, a worm gearbox has right hand threads; to change the direction of the output, a left-hands thread worm gearbox is required.

Ever-Power EP series triple-reduction worm gear rate reducers are available 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 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 can be found in four configurations: horizontal, vertical, shafted, and shaft mounted.

These reducers are ideal for water/waste-water products drive applications such as thickeners and clarifiers, which require a vertical down shaft. Other obtainable configurations also make Ever-Power triple reduction reducers perfect for make use of on mixers, elevators, solar power panels, astronomical telescopes, indexing tables, hoists, conveyors, or additional process or materials handling systems where huge torques/sluggish speeds are needed.

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

Enclosed Gears / Gearboxes
Enclosed gears, also called gearboxes or rate reducers, are open gears contained in a housing. The housing 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 speed ratios.

The purpose of a gearbox is to improve or reduce speed. Consequently, torque output will be the inverse of the function. If the enclosed drive is a acceleration reducer, the torque output increase; if the drive boosts speed, the torque result will reduce. Gear drive selection elements include: shaft orientation, speed 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 quickness reducer can achieve up to a 100:1 decrease ratio in a small package. Referred to as right angle drives, these contain a cylindrical worm with screw threads and a worm. With an individual start worm, the worm gear advances only one tooth for each 360-degree switch of the worm. So, whatever the worm’s size, the apparatus ratio may be the ‘size of the worm gear to 1′. Higher reduction ratios can be created through the use of double and triple reduction ratios.

Helical Gear Speed Reducers
Provide high-efficiency speed reduction through 1, 2, 3, or 4 models of gears. Power is definitely 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 will be the concentric (insight and result shafts are in series) and parallel shaft (insight and result shafts are offset). Single-stage helical equipment reducers are usually used for equipment ratios up to about 8:1. Where decrease speeds and higher ratios are needed, double, triple, and quadruple equipment reduction stages can be used.

Cycloidal Disc Speed Reducers
Different from conventional gearing because they operate with out a high velocity pinion or equipment teeth, and the components operate in compression rather than shear. This is because of the style of the cycloidal discs that roll within a band gear housing, comparable to a planetary style. The primary components are the eccentric cam, the internally flanged result 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, which have feet for bolting, are the most common.

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

A gearmotor combines an enclosed gearset with a motor. A motorized reducer resembles a gearmotor except that it is driven by another NEMA C-face motor.

Seals and Breathers
Seals are used between the gear housing and input and output shafts to retain essential oil and block dirt. The most commonly used type, the radial lip seal, consists of a steel casing that fits in to the casing bore and an elastomeric sealing lip that presses on the shaft. Labyrinth seals are make use of for high-quickness applications, and contain a housing with some bands that limit leakage. A breather is usually a connect with a hole that’s mounted in the apparatus housing allowing airflow and relieve inner pressure.

Lubrication
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 types consist of grease and solid film. Grease can be utilized for worm, planetary, cycloidal, and hypoidal reducers. Common distribution methods are a splash worm reduction gearbox program and a circulating system
Worm Reduction Gearbox App:

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