Right angle gearboxes (worm and planetary) are tough and built for 90° turns. Inline reducers (parallel shaft and planetary) are a perfect match for motors with high input speeds, or when gearmotor efficiency is important. Get in touch with our technical sales staff for help determining which gearbox remedy 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 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 correct angle gearboxes are designed with five mounting choices providing versatility when incorporating the reducer into product.
RIGHT ANGLE BEVEL GEARBOX
The proper 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 right angle planetary gearboxes offer a robust solution. The right angle bevel gearbox will come 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 little planetary gearbox configurations provide the smallest footprint and quietest operation of our quickness reducers. These gearboxes are created to deal with varying loads with small backlash. With frame 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-delicate applications.
INLINE PLANETARY GEARBOX
Our inline planetary gearbox configurations supply the highest efficiency and best result torque of most our swiftness reducers. These gearboxes are designed to handle varying loads with small backlash. Planetary gear reducers operate more quietly than parallel shaft reducers. With 18 ratio options which range from 5:1 to 1000:1, we have a solution to suit your needs.
PARALLEL SHAFT GEARBOX
Parallel shaft gearboxes are the top choice for continuous duty applications. Their equipment cluster design provides a highly effective method for dissipating heat. Parallel shaft gearboxes possess the shortest length of our inline equipment reducer options so they work well in conditions with limited space. Our parallel shaft equipment reducers offer an affordable drop-in replacement 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 decrease boxes feature a gear arrangement when a gear in the kind of a screw, also known as a worm, meshes with a worm gear. These gears are typically made from bronze and the worms are metal 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 equipment reducers is usually that they produce an output that is 90° from the insight and can be used to transmit higher torque or reduce rotational speed. Most often, a worm gearbox provides right hand threads; to change the path of the result, a left-hand thread worm gearbox is necessary.

Ever-Power EP series triple-reduction worm gear swiftness reducers are available in ratios from 5000:1 to 175,000:1 and center distances from 7” to 20” (larger sizes available on request). Result torque ranges from 33,000 in pounds. 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 are available in four configurations: horizontal, vertical, shafted, and shaft installed.
These reducers are well suited for water/waste-water products drive applications such as for example thickeners and clarifiers, which need a vertical straight down shaft. Other obtainable configurations also make Ever-Power triple reduction reducers perfect for use on mixers, elevators, solar panels, astronomical telescopes, indexing tables, hoists, conveyors, or various other process or materials handling systems where large torques/sluggish speeds are needed.
These reducers are also obtainable with a helical major reduction stage and are termed the HDVM series
Enclosed Gears / Gearboxes
Enclosed gears, also referred to as gearboxes or velocity reducers, are open gears contained in a housing. The casing supports bearings and shafts, keeps in lubricants, and protects the elements from surrounding conditions. Gearboxes are available in an array of load capacities and quickness ratios.
The purpose of a gearbox is to improve or reduce speed. Consequently, torque output will be the inverse of the function. If the enclosed drive can be a speed reducer, the torque output increase; if the drive increases speed, the torque result will decrease. Gear drive selection factors include: shaft orientation, quickness ratio, design type, nature of load, gear ranking, environment, mounting position, operating temperature range, and lubrication.
Basic Types of Gearboxes
Worm Gear Speed Reducers
A single reduction swiftness reducer can achieve up to 100:1 reduction ratio in a little package. Known as right position drives, these contain a cylindrical worm with screw threads and a worm. With a single start worm, the worm equipment advances only one tooth for each 360-degree turn of the worm. So, whatever the worm’s size, the gear ratio may be the ‘size of the worm gear to 1′. Higher decrease ratios can 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 is certainly transmitted from a high-quickness pinion to a slower-speed equipment. Helical gears generally operate with their shafts parallel to each other. Both most common types will be the concentric (input and output shafts are in collection) and parallel shaft (insight and result shafts are offset). Single-stage helical equipment reducers are usually used for gear ratios up to about 8:1. Where reduced speeds and higher ratios are needed, double, 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 gear teeth, and the elements operate in compression instead of shear. This is because of the design of the cycloidal discs that roll within a ring gear housing, comparable to a planetary design. 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) Base 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 possess a hollow output shaft that slips more than the driven shaft.
A gearmotor combines a specific gearset with a motor. A motorized reducer resembles a gearmotor except that it’s driven by a separate NEMA C-face motor.
Seals and Breathers
Seals are used between your gear housing and input and output shafts to retain oil and block dirt. The mostly used type, the radial lip seal, consists of a metal casing that fits into the casing bore and an elastomeric sealing lip that presses on the shaft. Labyrinth seals are make use of for high-velocity applications, and consist of a housing with some rings that limit leakage. A breather is definitely a connect with a hole that is mounted in the gear housing allowing airflow and relieve inner pressure.
Enclosed gears are usually lubricated with oil. The most typical types of essential oil are rust and oxidation inhibiting, severe pressure, compounded, and synthetic. Other styles include grease and solid film. Grease can be utilized 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 method of substantially decreasing velocity and increasing torque. Little 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, especially when the worm drive’s compactness is considered.
Worm drives are found in presses, in rolling mills, in conveying engineering, in mining industry machines, and on rudders. Furthermore, milling heads and rotary tables sit using high-precision duplex worm drives with adjustable backlash.
