GEARBOX REDUCERS
Correct angle gearboxes (worm and planetary) are tough and built for 90° turns. Inline reducers (parallel shaft and planetary) are an ideal match for motors with high input speeds, or when gearmotor effectiveness is important. Get in touch with our technical sales personnel for help identifying which gearbox answer 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 output. The reducers come in 12 ratios ranging from 5:1 to 100:1, with non-back-drivable ratios 30:1 and higher. Our right angle gearboxes are designed with five mounting options providing versatility when incorporating the reducer into item.
RIGHT ANGLE BEVEL GEARBOX

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 supply the highest efficiency and best result torque of all our quickness reducers. These gearboxes are designed to manage varying loads with little 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 are the best choice for constant duty applications. Their equipment cluster design provides a highly effective method for dissipating heat. Parallel shaft gearboxes have the shortest amount of our inline equipment reducer options therefore they work well in environments with limited space. Our parallel shaft equipment reducers offer an affordable drop-in replacement solution for most little parallel shaft gearmotors.
Wormwheel gearboxes pass several names, including 90-degree gearboxes, right position gearboxes, swiftness reducers, worm gear reducers and worm drive gearboxes. Gear decrease boxes include a gear arrangement in which a equipment in the form of a screw, also known as a worm, meshes with a worm gear. These gears are usually 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 principal benefit of worm gear reducers is that they generate an output that is 90° from the input 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 required.

Ever-Power EP series triple-reduction worm gear swiftness reducers are available in ratios from 5000:1 to 175,000:1 and center distances from 7” to 20” (larger sizes on request). Result 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 installed.

These reducers are well suited for water/waste-water tools drive applications such as for example thickeners and clarifiers, which require a vertical down shaft. Other available configurations also make Ever-Power triple decrease reducers perfect for make use of on mixers, elevators, solar power panels, astronomical telescopes, indexing tables, hoists, conveyors, or additional process or components handling systems where large torques/sluggish speeds are needed.

These reducers are also obtainable with a helical principal reduction stage and are termed the HDVM series

Enclosed Gears / Gearboxes
Enclosed gears, also called gearboxes or swiftness reducers, are open gears within a housing. The casing supports bearings and shafts, retains in lubricants, and protects the parts from surrounding conditions. Gearboxes are available in a wide selection of load capacities and rate ratios.

The objective of a gearbox is to improve or reduce speed. Consequently, torque output would be the inverse of the function. If the enclosed drive is certainly a acceleration reducer, the torque result will increase; if the drive raises speed, the torque result will decrease. Gear drive selection factors include: shaft orientation, quickness ratio, design type, nature of load, gear ranking, environment, mounting position, operating temperature range, and lubrication.

Basic Types of Gearboxes

Worm Gear Speed Reducers
A single reduction acceleration reducer can achieve up to 100:1 decrease ratio in a little package. Known as right position drives, these contain a cylindrical worm with screw threads and a worm. With a single begin worm, the worm gear advances only one tooth for every 360-degree change of the worm. So, whatever the worm’s size, the apparatus ratio is the ‘size of the worm gear to 1′. Higher reduction ratios could 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 transmitted from a high-rate pinion to a slower-speed equipment. Helical gears usually operate with their shafts parallel to one another. Both most common types will be the concentric (insight and result shafts are in range) and parallel shaft (insight and result shafts are offset). Single-stage helical gear reducers are usually used for gear ratios up to about 8:1. Where cheaper speeds and higher ratios are necessary, dual, triple, and quadruple equipment reduction stages can be used.

Cycloidal Disc Speed Reducers
Not the same as conventional gearing because they operate without a high speed pinion or gear teeth, and the elements operate in compression rather than shear. This is because of 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) Foundation 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 electric 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 your gear housing and insight and output shafts to retain oil and prevent dirt. The mostly used type, the radial lip seal, includes a metallic casing that fits in to the casing bore and an elastomeric sealing lip that presses on the shaft. Labyrinth seals are use for high-rate applications, and consist of a housing with some bands that limit leakage. A breather can be a plug 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 common types of oil are rust and oxidation inhibiting, extreme pressure, compounded, and synthetic. Other types include grease and solid film. Grease can be used for worm, planetary, cycloidal, and hypoidal reducers. Common distribution strategies are a splash program and a circulating system
Worm Reduction Gearbox App:

Worm drives certainly are a compact method 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 might be suitable for, specially when the worm drive’s compactness is known as.

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