GEARBOX REDUCERS
Right angle gearboxes (worm and planetary) are rugged and built for 90° turns. Inline reducers (parallel shaft and planetary) are an ideal match for motors with high insight speeds, or when gearmotor performance is important. Get in touch with our technical sales staff for help determining which gearbox solution is best for you.
RIGHT ANGLE REDUCERS
WORM GEAR REDUCER
EP’s worm gear 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 which range from 5:1 to 100:1, with non-back-drivable ratios 30:1 and higher. Our correct angle gearboxes are designed with five mounting options providing versatility when incorporating the reducer into product.
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 solid and efficient correct angle configuration, our right angle planetary gearboxes offer a robust solution. The proper 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
Our I-Series small planetary gearbox configurations supply the smallest footprint and quietest procedure of our speed reducers. These gearboxes are made to deal with varying loads with little backlash. With body sizes 52cm, 62cm, and 81cm, 12 ratios ranging from 5:1 to 308:1, we’ve a solution to suit your needs. Our 52 frame size is also available with plastic gears for noise-sensitive applications.
INLINE PLANETARY GEARBOX
inline-planetary-gearbox
Our inline planetary gearbox configurations supply the highest efficiency and best output torque of most our speed reducers. These gearboxes are made to deal with varying loads with small backlash. Planetary equipment reducers operate more quietly than parallel shaft reducers. With 18 ratio choices ranging 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 constant duty applications. Their gear cluster design provides a highly effective method for dissipating heat. Parallel shaft gearboxes possess the shortest amount of our inline equipment reducer options therefore they work well in environments with limited space. Our parallel shaft gear reducers provide an affordable drop-in alternative solution for most small parallel shaft gearmotors.
Wormwheel gearboxes pass several names, including 90-degree gearboxes, right angle gearboxes, swiftness reducers, worm equipment reducers and worm drive gearboxes. Gear decrease boxes feature a gear arrangement in which a gear in the form of a screw, also referred to as a worm, meshes with a worm gear. 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 significantly smaller than other gear reduction boxes. A major benefit of worm equipment reducers is that they create an output that is 90° from the insight and can be used to transmit higher torque or decrease rotational speed. Frequently, a worm gearbox offers right hand threads; to change the direction of the output, a left-hand thread worm gearbox is necessary.

Ever-Power EP series triple-reduction worm gear swiftness reducers can be found 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 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 perfect for water/waste-water devices drive applications such as thickeners and clarifiers, which require a vertical down shaft. Other available configurations also make Ever-Power triple reduction reducers perfect for use on mixers, elevators, solar power 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 available with a helical primary reduction stage and so are termed the HDVM series

Enclosed Gears / Gearboxes
Enclosed gears, also called gearboxes or acceleration reducers, are open gears within a housing. The casing facilitates bearings and shafts, retains in lubricants, and protects the elements from surrounding conditions. Gearboxes can be found in an array of load capacities and velocity ratios.

The objective of a gearbox is to improve or reduce speed. As a result, torque output would be the inverse of the function. If the enclosed drive is a acceleration reducer, the torque output will increase; if the drive worm reduction gearbox improves speed, the torque output will reduce. Gear drive selection elements include: shaft orientation, quickness ratio, design type, character 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 position drives, these contain a cylindrical worm with screw threads and a worm. With an individual start worm, the worm equipment advances only 1 tooth for every 360-degree turn 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 through the use of double and triple decrease ratios.

Helical Gear Speed Reducers
Provide high-efficiency speed decrease through 1, 2, 3, or 4 pieces of gears. Power is definitely transmitted from a high-acceleration 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 (input and result shafts are offset). Single-stage helical gear reducers are typically used for equipment ratios up to about 8:1. Where decrease speeds and higher ratios are required, dual, triple, and quadruple equipment reduction stages may be used.

Cycloidal Disc Speed Reducers
Different from conventional gearing because they operate with out a high swiftness pinion or equipment teeth, and the parts operate in compression rather than shear. This is due to the design of the cycloidal discs that roll within a ring gear housing, similar to a planetary style. The main components will be the eccentric cam, the internally flanged output shaft, the discs, and the ring gear casing.

Three Mounting Options
(L-R) Bottom 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 over the driven shaft.

A gearmotor combines an enclosed gearset with a motor. 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 insight and result shafts to retain oil and block dirt. The most commonly utilized type, the radial lip seal, includes a metal casing that fits into the housing bore and an elastomeric sealing lip that presses on the shaft. Labyrinth seals are use for high-acceleration applications, and contain a housing with some rings that limit leakage. A breather is a plug with a hole that is mounted in the gear 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 styles include 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 App:

Worm drives certainly are a compact means of substantially decreasing speed and increasing torque. Little electric motors are generally high-speed and low-torque; the addition of a worm drive increases the selection of applications that it may be suitable for, particularly when the worm drive’s compactness is considered.

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