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 personnel for help identifying which gearbox option is best for you.
RIGHT ANGLE REDUCERS
WORM GEAR REDUCER
EP’s worm gear reducers are designed with a hollow bore and allow for a corner switch with optional dual result. 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 are designed with five mounting options providing flexibility when incorporating the reducer into product.
RIGHT ANGLE BEVEL GEARBOX
The right angle bevel gearbox combines the top features of our correct angle worm and planetary inline reducers. With a solid and efficient correct angle configuration, our correct angle planetary gearboxes offer a robust solution. The proper angle bevel gearbox will come in 18 ratios ranging from 5:1 to 1000:1, in fact it is back-drivable at all ratios.
I-SERIES PLANETARY GEARBOX
Our I-Series small planetary gearbox configurations supply the smallest footprint and quietest procedure of our rate reducers. These gearboxes are created to handle varying loads with little backlash. With framework sizes 52cm, 62cm, and 81cm, 12 ratios ranging from 5:1 to 308:1, we’ve a solution to fit your needs. Our 52 frame size can be available with plastic-type gears for noise-sensitive applications.
INLINE PLANETARY GEARBOX
Our inline planetary gearbox configurations supply the highest efficiency and best output torque of most our rate reducers. These gearboxes are created to handle varying loads with little 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 gearboxes will be the best choice for continuous duty applications. Their gear cluster design provides an effective method for dissipating warmth. Parallel shaft gearboxes possess the shortest length of our inline gear reducer options so they work very well in environments with limited space. Our parallel shaft gear reducers provide an affordable drop-in alternative solution for most little parallel shaft gearmotors.
Wormwheel gearboxes go by several names, including 90-degree gearboxes, right position gearboxes, speed reducers, worm equipment reducers and worm drive gearboxes. Gear decrease boxes feature a gear arrangement in which a equipment in the type of a screw, also called a worm, meshes with a worm equipment. These gears are usually made from bronze and the worms are metal or stainless steel.
While worm gears are similar to a spur gear, the worm gearboxes are considerably smaller than other equipment reduction boxes. A principal benefit of worm equipment reducers is certainly that they create an output that’s 90° from the input and can be utilized to transmit higher torque or reduce rotational speed. Frequently, a worm gearbox offers right hand threads; to improve the direction of the result, a left-hands thread worm gearbox is necessary.

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 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 tools drive applications such as for example thickeners and clarifiers, which require a vertical straight down shaft. Other obtainable 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/sluggish speeds are needed.
These reducers are also offered with a helical principal 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 casing supports bearings and shafts, holds in lubricants, and protects the elements from surrounding conditions. Gearboxes can be found in a wide range of load capacities and acceleration ratios.
The objective of a gearbox is to improve or reduce speed. Consequently, torque output will be the inverse of the function. If the enclosed drive is certainly a swiftness reducer, the torque output increase; if the drive increases speed, the torque output will decrease. Gear drive selection factors include: shaft orientation, swiftness ratio, design type, character of load, gear rating, environment, mounting position, operating temperature range, and lubrication.
Basic Types of Gearboxes
Worm Gear Speed Reducers
A single reduction velocity reducer can achieve up to 100:1 reduction ratio in a little package. Known as right position drives, these consist of a cylindrical worm with screw threads and a worm. With a single begin worm, the worm gear advances only 1 tooth for each 360-degree convert of the worm. So, whatever the worm’s size, the apparatus ratio may be the ‘size of the worm equipment to 1′. Higher decrease ratios can be created through the use of double and triple reduction ratios.
Helical Gear Speed Reducers
Provide high-efficiency speed decrease through 1, 2, 3, or 4 pieces of gears. Power is certainly transmitted from a high-swiftness pinion to a slower-speed gear. Helical gears generally operate with their shafts parallel to each other. The two most common types will be the concentric (insight and output shafts are in series) and parallel shaft (insight and output shafts are offset). Single-stage helical gear reducers are usually used for equipment ratios up to about 8:1. Where decrease speeds and higher ratios are needed, dual, triple, and quadruple gear reduction stages may be used.
Cycloidal Disc Speed Reducers
Not the same as conventional gearing because they operate with out a high quickness pinion or equipment teeth, and the parts operate in compression rather than shear. This is because of the style of the cycloidal discs that roll within a band gear housing, similar to a planetary design. 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 have a hollow output shaft that slips over the driven shaft.
A gearmotor combines an enclosed gearset with a engine. A motorized reducer resembles a gearmotor except that it’s driven by another NEMA C-face motor.
Seals and Breathers
Seals are used between the gear housing and insight and result shafts to retain oil and prevent dirt. The mostly used type, the radial lip seal, contains 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-quickness applications, and contain a housing with some bands that limit leakage. A breather can be a connect with a hole that is mounted in the gear housing to permit airflow and relieve internal pressure.
Enclosed gears are usually lubricated with oil. The most typical types of essential 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 Software:
Worm drives certainly are a compact method of substantially decreasing velocity 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, especially when the worm drive’s compactness is known as.
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.
