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 performance is important. Contact our technical sales staff for help identifying which gearbox alternative is best for you.
RIGHT ANGLE REDUCERS
WORM GEAR REDUCER
EP’s worm equipment reducers were created with a hollow bore and allow for a corner convert 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 flexibility when incorporating the reducer into product.
RIGHT ANGLE BEVEL GEARBOX
The proper angle bevel gearbox combines the features of our right angle worm and planetary inline reducers. With a good and efficient right angle configuration, our right angle planetary gearboxes offer a robust solution. The proper angle bevel gearbox comes in 18 ratios which range from 5:1 to 1000:1, in fact it is back-drivable at all ratios.
I-SERIES PLANETARY GEARBOX
Our I-Series little planetary gearbox configurations provide the smallest footprint and quietest procedure of our acceleration reducers. These gearboxes are designed to manage varying loads with small backlash. With framework sizes 52cm, 62cm, and 81cm, 12 ratios ranging from 5:1 to 308:1, we have a solution to fit your needs. Our 52 frame size can be available with plastic-type material gears for noise-sensitive applications.
INLINE PLANETARY GEARBOX
Our inline planetary gearbox configurations supply the highest efficiency and best result torque of all our rate reducers. These gearboxes are created to manage varying loads with little backlash. Planetary gear reducers operate more quietly than parallel shaft reducers. With 18 ratio choices which range from 5:1 to 1000:1, we have a solution to suit your needs.
PARALLEL SHAFT GEARBOX
Parallel shaft gearboxes will be the top choice for constant duty applications. Their gear cluster design provides a highly effective method for dissipating temperature. Parallel shaft gearboxes possess the shortest amount of our inline gear reducer options therefore they work 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 go by several names, including 90-degree gearboxes, right angle gearboxes, swiftness reducers, worm equipment reducers and worm drive gearboxes. Gear decrease boxes include a gear arrangement when a equipment in the type of a screw, also called a worm, meshes with a worm gear. These gears are usually made from bronze and the worms are metal or stainless steel.
While worm gears act like a spur equipment, the worm gearboxes are considerably smaller than other gear reduction boxes. A major benefit of worm gear reducers is certainly that they generate an output that’s 90° from the input and can be utilized to transmit higher torque or decrease rotational speed. Frequently, a worm gearbox has right hand threads; to improve the path of the result, a left-hand thread worm gearbox is necessary.

GEAR RATIO 10:1
Ever-Power EP series triple-reduction worm gear acceleration reducers can be found in ratios from 5000:1 to 175,000:1 and middle 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 insight 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 well suited for water/waste-water gear drive applications such as for example thickeners and clarifiers, which require a vertical down shaft. Other offered configurations also make Ever-Power triple reduction reducers perfect for use on mixers, elevators, solar panels, astronomical telescopes, indexing tables, hoists, conveyors, or other process or components handling systems where huge torques/gradual speeds are needed.
These reducers are also obtainable with a helical major reduction stage and so are termed the HDVM series
Enclosed Gears / Gearboxes
Enclosed gears, also referred to as gearboxes or speed reducers, are open gears contained in a housing. The casing supports bearings and shafts, retains in lubricants, and protects the parts 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 will be the inverse of the function. If the enclosed drive is certainly a speed reducer, the torque result increase; if the drive increases speed, the torque result will reduce. Gear drive selection factors 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 rate reducer can achieve up to 100:1 reduction ratio in a little package. Known as right angle 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 each 360-degree convert of the worm. So, regardless of the worm’s size, the apparatus ratio is the ‘size of the worm equipment to 1′. Higher decrease ratios could be created by using double and triple reduction ratios.
Helical Gear Speed Reducers
Provide high-efficiency speed reduction through 1, 2, 3, or 4 models of gears. Power can be transmitted from a high-swiftness pinion to a slower-speed equipment. Helical gears usually operate with their shafts parallel to each other. The two most common types are the concentric (input and result shafts are in series) and parallel shaft (input and result shafts are offset). Single-stage helical equipment reducers are usually used for gear ratios up to about 8:1. Where reduce speeds and higher ratios are needed, double, triple, and quadruple equipment reduction stages can be used.
Cycloidal Disc Speed Reducers
Not the same as conventional gearing because they operate with out a high velocity pinion or gear teeth, and the parts operate in compression rather than shear. This is due to the style of the cycloidal discs that roll within a ring gear housing, similar to a planetary design. The primary components will be the eccentric cam, the internally worm reduction gearbox 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, which have feet for bolting, will be 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 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 the gear housing and insight and output shafts to retain essential oil and block dirt. The mostly utilized type, the radial lip seal, includes a steel casing that fits into the housing 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 rings that limit leakage. A breather can be a connect with a hole that is mounted in the apparatus housing allowing airflow and relieve internal pressure.
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 include grease and solid film. Grease can be used for worm, planetary, cycloidal, and hypoidal reducers. Common distribution methods are a splash system and a circulating system
Worm Reduction Gearbox App:
Worm drives are a compact means of substantially decreasing acceleration and increasing torque. Small 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, specially when the worm drive’s compactness is known as.
Worm drives are found in presses, in rolling mills, in conveying engineering, in mining industry devices, and on rudders. Furthermore, milling heads and rotary tables are positioned using high-precision duplex worm drives with adjustable backlash.
