Correct 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. Contact our technical sales personnel for help identifying which gearbox solution is best for you.
RIGHT ANGLE REDUCERS
WORM GEAR REDUCER
EP’s worm gear reducers were created with a hollow bore and allow for a corner change with optional dual result. 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 are designed with five mounting choices providing versatility when incorporating the reducer into item.
RIGHT ANGLE BEVEL GEARBOX
The proper 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 proper angle bevel gearbox will come 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 small planetary gearbox configurations provide the smallest footprint and quietest operation of our quickness reducers. These gearboxes are made to manage varying loads with small backlash. With framework sizes 52cm, 62cm, and 81cm, 12 ratios which range from 5:1 to 308:1, we’ve a solution to fit your needs. Our 52 frame size is also available with plastic-type gears for noise-sensitive applications.
INLINE PLANETARY GEARBOX
Our inline planetary gearbox configurations provide the highest performance and best output torque of all our swiftness reducers. These gearboxes are designed to manage varying loads with little backlash. Planetary gear 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 equipment cluster design provides an effective method for dissipating heat. Parallel shaft gearboxes possess the shortest length of our inline equipment reducer options therefore they work well in conditions with limited space. Our parallel shaft gear reducers offer an affordable drop-in alternative solution for most small parallel shaft gearmotors.
Wormwheel gearboxes go by several names, including 90-degree gearboxes, right position gearboxes, speed reducers, worm gear reducers and worm drive gearboxes. Gear reduction boxes feature a gear arrangement when a equipment in the kind of a screw, also referred to as a worm, meshes with a worm gear. These gears are typically created from bronze and the worms are metal or stainless steel.
While worm gears are similar to a spur equipment, the worm gearboxes are considerably smaller than other equipment reduction boxes. A principal benefit of worm gear reducers is certainly that they produce an output that’s 90° from the input and can be used to transmit higher torque or decrease rotational speed. Frequently, a worm gearbox has right hand threads; to improve the path 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 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 input 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 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 make use of on mixers, elevators, solar panels, astronomical telescopes, indexing tables, hoists, conveyors, or other process or materials handling systems where large torques/gradual speeds are needed.
These reducers are also available with a helical principal reduction stage and so are termed the HDVM series
Enclosed Gears / Gearboxes
Enclosed gears, also known as gearboxes or rate reducers, are open gears within a housing. The casing supports bearings and shafts, holds 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 increase or reduce speed. Because of this, torque output will be the inverse of the function. If the enclosed drive is a quickness reducer, the torque output will increase; if the drive increases speed, the torque output will reduce. Gear drive selection elements include: shaft orientation, rate ratio, design type, character 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 a 100:1 decrease ratio in a small package. Known as right angle drives, these consist of a cylindrical worm with screw threads and a worm. With an individual start worm, the worm gear advances only 1 tooth for every 360-degree switch of the worm. So, whatever the worm’s size, the apparatus ratio may be 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 reduction through 1, 2, 3, or 4 pieces of gears. Power is definitely transmitted from a high-swiftness pinion to a slower-speed gear. Helical gears usually operate with their shafts parallel to one another. The two most common types will be the concentric (input and output shafts are in collection) and parallel shaft (input and output shafts are offset). Single-stage helical gear reducers are usually used for gear ratios up to about 8:1. Where decrease speeds and higher ratios are required, dual, triple, and quadruple gear reduction stages can be used.
Cycloidal Disc Speed Reducers
Different from conventional gearing because they operate without a high swiftness pinion or gear teeth, and the elements operate in compression instead of shear. This is due to the design of the cycloidal discs that roll within a band gear housing, similar to a planetary design. The primary components will be the worm reduction gearbox eccentric cam, the internally flanged output shaft, the discs, and the ring gear housing.
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 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 insight and output shafts to retain oil and block dirt. The mostly utilized type, the radial lip seal, contains a metallic casing that fits in to the casing bore and an elastomeric sealing lip that presses on the shaft. Labyrinth seals are make use of for high-speed applications, and consist of a housing with a series of bands that limit leakage. A breather is certainly a plug with a hole that is mounted in the gear housing allowing airflow and relieve internal pressure.
Enclosed gears are generally lubricated with oil. The most typical types of oil are rust and oxidation inhibiting, extreme 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 program and a circulating system
Worm Reduction Gearbox Program:
Worm drives are a compact means of substantially decreasing rate 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 might be suitable for, specially when the worm drive’s compactness is known as.
Worm drives are used 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.
