Correct angle gearboxes (worm and planetary) are durable and built for 90° turns. Inline reducers (parallel shaft and planetary) are an ideal match for motors with high input speeds, or when gearmotor efficiency is important. Contact our technical sales staff for help identifying which gearbox alternative is most beneficial for you.
RIGHT ANGLE REDUCERS
WORM GEAR REDUCER
EP’s worm equipment reducers were created with a hollow bore and invite for a corner turn 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 correct angle gearboxes were created with five mounting choices providing flexibility when incorporating the reducer into product.
RIGHT ANGLE BEVEL GEARBOX
The right angle bevel gearbox combines the features of our right angle worm and planetary inline reducers. With a solid and efficient right angle configuration, our right angle planetary gearboxes offer a robust solution. The right angle bevel gearbox will come in 18 ratios which range 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 operation of our acceleration reducers. These gearboxes are designed to manage varying loads with little 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 is also available with plastic gears for noise-delicate applications.
INLINE PLANETARY GEARBOX
Our inline planetary gearbox configurations provide the highest effectiveness and best result torque of most our swiftness reducers. These gearboxes are designed to manage 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 have 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 temperature. Parallel shaft gearboxes have the shortest length of our inline gear reducer options so 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, velocity reducers, worm gear reducers and worm drive gearboxes. Gear reduction boxes include a gear arrangement in which a equipment in the kind of a screw, also called 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 significantly smaller than other gear reduction boxes. A primary benefit of worm gear reducers is definitely that they generate an output that’s 90° from the insight and can be utilized to transmit higher torque or decrease rotational speed. Frequently, a worm gearbox has right hand threads; to improve the direction of the output, a left-hand thread worm gearbox is necessary.

Ever-Power EP series triple-reduction worm gear speed 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 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 perfect for water/waste-water apparatus drive applications such as thickeners and clarifiers, which require a vertical down shaft. Other obtainable 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 materials handling systems where huge torques/slower speeds are needed.
These reducers are also obtainable with a helical principal reduction stage and so are termed the HDVM series
Enclosed Gears / Gearboxes
Enclosed gears, also called gearboxes or swiftness reducers, are open gears within a housing. The casing facilitates bearings and shafts, keeps in lubricants, and protects the components from surrounding circumstances. Gearboxes are available in an array of load capacities and acceleration ratios.
The purpose 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 acceleration reducer, the torque result will increase; if the drive improves speed, the torque result will decrease. Gear drive selection elements include: shaft orientation, speed ratio, design type, nature of load, gear rating, environment, mounting position, operating 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 small package. Known as right position drives, these consist of a cylindrical worm with screw threads and a worm. With an individual start worm, the worm equipment advances only one tooth for every 360-degree change of the worm. So, regardless of the worm’s size, the apparatus ratio may be the ‘size of the worm equipment to 1′. Higher decrease 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 units of gears. Power is definitely transmitted from a high-rate pinion to a slower-speed equipment. Helical gears generally operate with their shafts parallel to one another. Both most common types are the concentric (insight and output shafts are in line) and parallel shaft (insight and result shafts are offset). Single-stage helical gear reducers are usually used for equipment ratios up to about 8:1. Where lower 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 rate pinion or gear teeth, and the elements operate in compression instead of shear. This is because of the style of the cycloidal discs that roll within a band 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 housing.
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, are 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 electric 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 the gear housing and input and result shafts to retain essential oil and block dirt. The most commonly utilized type, the radial lip seal, includes a metallic casing that fits in to the housing bore and an elastomeric sealing lip that presses on the shaft. Labyrinth seals are use for high-velocity applications, and consist of a housing with a series of rings that limit leakage. A breather can be a connect with a hole that’s mounted in the apparatus housing allowing airflow and relieve inner pressure.
Enclosed gears are generally lubricated with oil. The most common types of oil are rust and oxidation inhibiting, extreme pressure, compounded, and synthetic. Other styles consist of grease and solid film. Grease can be utilized for worm, planetary, cycloidal, and hypoidal reducers. Common distribution methods are a splash system and a circulating system
Worm Reduction Gearbox Application:
Worm drives are a compact means of substantially decreasing speed 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 could be suitable for, specially when the worm drive’s compactness is considered.
Worm drives are used in presses, in rolling mills, in conveying engineering, in mining sector machines, and on rudders. Furthermore, milling heads and rotary tables are positioned using high-precision duplex worm drives with adjustable backlash.
