Correct angle gearboxes (worm and planetary) are durable and built for 90° turns. Inline reducers (parallel shaft and planetary) are a perfect match for motors with high insight speeds, or when gearmotor efficiency is important. Get in touch with our technical sales personnel for help determining which gearbox alternative is best for you.
RIGHT ANGLE REDUCERS
WORM GEAR REDUCER
EP’s worm gear reducers are designed with a hollow bore and invite for a corner turn with optional dual result. The reducers can be found in 12 ratios ranging from 5:1 to 100:1, with non-back-drivable ratios 30:1 and higher. Our right angle gearboxes were created with five mounting options providing flexibility when incorporating the reducer into product.
RIGHT ANGLE BEVEL GEARBOX
The proper angle bevel gearbox combines the top features of our right angle worm and planetary inline reducers. With a good 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 provide the smallest footprint and quietest procedure of our quickness 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’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 supply the highest performance and best result torque of all our speed reducers. These gearboxes are designed to handle varying loads with little backlash. Planetary equipment reducers operate more quietly than parallel shaft reducers. With 18 ratio options ranging from 5:1 to 1000:1, we have a solution to fit your needs.
PARALLEL SHAFT GEARBOX
Parallel shaft gearboxes will be the top choice for continuous duty applications. Their gear cluster design provides a highly effective method for dissipating warmth. Parallel shaft gearboxes have the shortest amount of our inline equipment reducer options so they work well in environments with limited space. Our parallel shaft gear reducers provide an affordable drop-in replacement solution for most little parallel shaft gearmotors.
Wormwheel gearboxes go by several names, including 90-degree gearboxes, right angle gearboxes, quickness reducers, worm equipment reducers and worm drive gearboxes. Gear reduction boxes include a gear arrangement when a gear in the kind of a screw, also called a worm, meshes with a worm equipment. These gears are typically made from bronze and the worms are steel or stainless steel.
While worm gears are similar to a spur gear, the worm gearboxes are significantly smaller than other gear reduction boxes. A principal benefit of worm gear reducers can be that they generate an output that’s 90° from the insight and can be used to transmit higher torque or reduce rotational speed. Frequently, a worm gearbox provides right hand threads; to improve the direction of the result, a left-hands thread worm gearbox is necessary.

GEAR RATIO 10:1
Ever-Power EP series triple-reduction worm gear rate reducers are available in ratios from 5000:1 to 175,000:1 and middle 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 pounds 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 can be found in four configurations: horizontal, vertical, shafted, and shaft installed.
These reducers are perfect for water/waste-water tools 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 make use of on mixers, elevators, solar power panels, astronomical telescopes, indexing tables, hoists, conveyors, or other process or materials 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 called gearboxes or rate reducers, are open gears contained in a housing. The casing facilitates bearings and shafts, holds in lubricants, and protects the parts from surrounding circumstances. Gearboxes are available in a wide range of load capacities and velocity ratios.
The purpose of a gearbox is to improve or reduce speed. Because of this, torque output will be the inverse of the function. If the enclosed drive is usually a rate reducer, the torque output increase; if the drive increases speed, the torque result will reduce. Gear drive selection factors include: shaft orientation, velocity ratio, design type, character of load, gear ranking, environment, mounting position, working temperature range, and lubrication.
Basic Types of Gearboxes
Worm Gear Speed Reducers
A single reduction swiftness reducer can achieve up to 100:1 decrease ratio in a little 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 1 tooth for each 360-degree switch of the worm. So, regardless of the worm’s size, the gear ratio is the ‘size of the worm equipment to 1′. Higher decrease ratios could be created by using double and triple decrease ratios.
Helical Gear Speed Reducers
Provide high-efficiency speed decrease through 1, 2, 3, or 4 pieces of gears. Power is transmitted from a high-acceleration pinion to a slower-speed equipment. Helical gears generally operate with their shafts parallel to each other. Both most common types are the concentric (input and result shafts are in collection) and parallel shaft (insight and output shafts are offset). Single-stage helical equipment reducers are typically used for equipment ratios up to about 8:1. Where decrease speeds and higher ratios are needed, double, triple, and quadruple equipment reduction stages can be used.
Cycloidal Disc Speed Reducers
Not the same as conventional gearing because they operate without a high speed pinion or gear teeth, and the components operate in compression instead of shear. This is because of the design of the cycloidal discs that roll within a ring gear housing, similar to a planetary style. The primary 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 have a hollow output shaft that slips more than the driven shaft.
A gearmotor combines an enclosed gearset with a 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 your gear housing and insight and result shafts to retain oil and prevent dirt. The mostly utilized type, the radial lip seal, consists of a metal casing that fits in to the housing bore and an elastomeric sealing lip that presses on the shaft. Labyrinth seals are make use of for high-acceleration applications, and consist of a housing with some bands that limit leakage. A breather is usually a connect with a hole that is mounted in the gear housing to permit airflow and relieve inner pressure.
Enclosed gears are generally lubricated with oil. The most typical types of essential oil are rust and oxidation inhibiting, extreme pressure, compounded, and synthetic. Other types consist of grease and solid film. Grease can be used for worm, planetary, cycloidal, and hypoidal reducers. Common distribution methods are a splash system and a circulating system
Worm Reduction Gearbox Program:
Worm drives certainly are a compact means of substantially decreasing quickness 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, especially when the worm drive’s compactness is considered.
Worm drives are used in presses, in rolling mills, in conveying engineering, in mining market devices, and on rudders. Furthermore, milling heads and rotary tables are positioned using high-precision duplex worm drives with adjustable backlash.
