Correct angle gearboxes (worm and planetary) are tough and built for 90° turns. Inline reducers (parallel shaft and planetary) are an ideal match for motors with high insight speeds, or when gearmotor effectiveness is important. Get in touch with our technical sales personnel for help identifying which gearbox alternative is best for you.
RIGHT ANGLE REDUCERS
WORM GEAR REDUCER
EP’s worm equipment reducers are designed with a hollow bore and allow for a corner convert with optional dual result. The reducers come 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 options worm reduction gearbox 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 correct angle planetary gearboxes provide a robust solution. The proper 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 little planetary gearbox configurations supply the smallest footprint and quietest procedure of our velocity 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 can be available with plastic gears for noise-sensitive applications.
INLINE PLANETARY GEARBOX
Our inline planetary gearbox configurations provide the highest effectiveness and best result torque of most our rate reducers. These gearboxes are made 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 have a solution to fit 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 amount of our inline equipment reducer options so they work well in environments with limited space. Our parallel shaft gear reducers offer an affordable drop-in substitute solution for most little parallel shaft gearmotors.
Wormwheel gearboxes go by several names, including 90-degree gearboxes, right angle gearboxes, speed reducers, worm equipment reducers and worm drive gearboxes. Gear reduction boxes feature a gear arrangement in which a gear in the form of a screw, also known as a worm, meshes with a worm equipment. These gears are usually made from bronze and the worms are steel or stainless steel.
While worm gears act like a spur gear, the worm gearboxes are considerably smaller than other gear reduction boxes. A major benefit of worm gear reducers is definitely that they produce an output that is 90° from the input and can be utilized to transmit higher torque or reduce rotational speed. Frequently, a worm gearbox has right hand threads; to improve the path of the result, a left-hands thread worm gearbox is required.

GEAR RATIO 10:1
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). 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 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 perfect for water/waste-water gear drive applications such as for example thickeners and clarifiers, which need a vertical down shaft. Other available configurations also make Ever-Power triple decrease reducers perfect for use on mixers, elevators, solar panels, astronomical telescopes, indexing tables, hoists, conveyors, or additional process or components handling systems where large torques/sluggish speeds are needed.
These reducers are also available with a helical primary reduction stage and so are termed the HDVM series
Enclosed Gears / Gearboxes
Enclosed gears, also referred to as gearboxes or speed reducers, are open gears within a housing. The casing facilitates bearings and shafts, holds in lubricants, and protects the parts from surrounding circumstances. Gearboxes are available in an array of load capacities and velocity ratios.
The objective of a gearbox is to improve or reduce speed. Because of this, torque output would be the inverse of the function. If the enclosed drive is certainly a quickness reducer, the torque result will increase; if the drive raises speed, the torque output will reduce. Gear drive selection elements include: shaft orientation, speed 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 speed reducer can achieve up to 100:1 decrease ratio in a small package. Known as right angle drives, these contain a cylindrical worm with screw threads and a worm. With an individual begin worm, the worm equipment advances only 1 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 gear 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 models of gears. Power is transmitted from a high-swiftness pinion to a slower-speed equipment. Helical gears generally operate with their shafts parallel to one another. Both most common types will be the concentric (insight and output shafts are in range) and parallel shaft (insight and output shafts are offset). Single-stage helical gear reducers are usually used for gear ratios up to about 8:1. Where reduce speeds and higher ratios are needed, double, triple, and quadruple equipment reduction stages can be used.
Cycloidal Disc Speed Reducers
Different from conventional gearing because they operate with out a high swiftness pinion or equipment teeth, and the parts operate in compression instead of shear. This is because of the design of the cycloidal discs that roll within a band gear housing, similar to a planetary design. The main components are 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, which 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 engine. 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 the gear housing and input and output shafts to retain essential oil and prevent dirt. The mostly utilized type, the radial lip seal, consists of a steel casing that fits in to the casing bore and an elastomeric sealing lip that presses on the shaft. Labyrinth seals are use for high-acceleration applications, and contain a housing with some bands that limit leakage. A breather is certainly a connect with a hole that is mounted in the apparatus housing to permit airflow and relieve internal pressure.
Enclosed gears are usually lubricated with oil. The most typical types of oil are rust and oxidation inhibiting, severe pressure, compounded, and synthetic. Other styles include grease and solid film. Grease can be used for worm, planetary, cycloidal, and hypoidal reducers. Common distribution strategies are a splash program and a circulating system
Worm Reduction Gearbox App:
Worm drives are a compact means of substantially decreasing rate and increasing torque. Small electric motors are usually high-speed and low-torque; the addition of a worm drive escalates the selection of applications that it could be suitable for, specially when the worm drive’s compactness is considered.
Worm drives are found in presses, in rolling mills, in conveying engineering, in mining sector devices, and on rudders. In addition, milling heads and rotary tables are positioned using high-precision duplex worm drives with adjustable backlash.
