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. Contact our technical sales staff for help determining which gearbox answer 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 turn with optional dual result. 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 right angle gearboxes are designed with five mounting options providing flexibility when incorporating the reducer into item.
RIGHT ANGLE BEVEL GEARBOX
The proper angle bevel gearbox combines the top features of our right angle worm and planetary inline reducers. With a solid and efficient right angle configuration, our correct angle planetary gearboxes offer a robust solution. The right angle bevel gearbox comes in 18 ratios ranging from 5:1 to 1000:1, and 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 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 fit your needs. Our 52 frame size can be available with plastic gears for noise-sensitive applications.
INLINE PLANETARY GEARBOX
Our inline planetary gearbox configurations provide the highest effectiveness and best output torque of most our rate reducers. These gearboxes are made 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’ve a solution to suit your needs.
PARALLEL SHAFT GEARBOX
Parallel shaft gearboxes will be the top choice for continuous duty applications. Their equipment cluster design provides a highly effective method for dissipating warmth. Parallel shaft gearboxes have the shortest amount of our inline gear 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 go by several names, including 90-degree gearboxes, right angle gearboxes, swiftness reducers, worm gear reducers and worm drive gearboxes. Gear reduction boxes include 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 usually that they create an output that is 90° from the input and can be utilized to transmit higher torque or decrease rotational speed. Most often, a worm gearbox offers right hand threads; to improve the path of the output, a left-hand thread worm gearbox is necessary.

GEAR RATIO 10:1
Ever-Power EP series triple-reduction worm gear swiftness reducers are available 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 lbs 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 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 decrease 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/gradual speeds are needed.
These reducers are also obtainable with a helical primary reduction stage and so are termed the HDVM series
Enclosed Gears / Gearboxes
Enclosed gears, also referred to as gearboxes or acceleration reducers, are open gears within a housing. The casing 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 velocity ratios.
The objective of a gearbox is to increase or reduce speed. Consequently, torque output would be the inverse of the function. If the enclosed drive is usually a acceleration reducer, the torque output will increase; if the drive improves speed, the torque result 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 velocity reducer can achieve up to a 100:1 reduction ratio in a small package. Known as right position drives, these consist of a cylindrical worm with screw threads and a worm. With a single start worm, the worm equipment advances only one tooth for every 360-degree change of the worm. So, whatever the worm’s size, the gear 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 sets of gears. Power can be 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 series) 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 cheaper speeds and higher ratios are required, dual, triple, and quadruple equipment reduction stages can be used.
Cycloidal Disc Speed Reducers
Different from conventional gearing because they operate with out a high speed 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 band gear housing, comparable 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) Bottom Mounted, Shaft-Mounted, Gearmotor
(L-R) Base-Mounted, Shaft-Mounted, Gearmotor
Base-mounted reducers, that 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 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 most commonly utilized type, the radial lip seal, contains a metallic 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 a series of rings that limit leakage. A breather is usually a plug with a hole that is mounted in the gear housing allowing airflow and relieve inner pressure.
Enclosed gears are generally lubricated with oil. The most typical types of essential oil are rust and oxidation inhibiting, severe 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 program and a circulating system
Worm Reduction Gearbox App:
Worm drives certainly are a compact means of substantially decreasing speed and increasing torque. Small electric motors are usually high-speed and low-torque; the addition of a worm drive increases the range of applications that it might 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.
