Correct angle gearboxes (worm and planetary) are rugged and built for 90° turns. Inline reducers (parallel shaft and planetary) are an ideal match for motors with high input speeds, or when gearmotor effectiveness is important. Contact our technical sales personnel for help determining 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 allow for a corner change 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 right 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 right angle worm and planetary inline reducers. With a good and efficient right angle configuration, our correct angle planetary gearboxes provide a robust solution. The proper 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 small planetary gearbox configurations supply the smallest footprint and quietest operation of our velocity 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 have a solution to fit your needs. Our 52 frame size can be available with plastic material gears for noise-sensitive applications.
INLINE PLANETARY GEARBOX
Our inline planetary gearbox configurations supply the highest effectiveness and best result torque of most our swiftness reducers. These gearboxes are made to manage varying loads with little backlash. Planetary gear reducers operate more quietly than parallel shaft reducers. With 18 ratio choices which range from 5:1 to 1000:1, we have a solution to suit your needs.
PARALLEL SHAFT GEARBOX
Parallel shaft gearboxes will be the best choice for continuous duty applications. Their gear cluster design provides a highly effective method for dissipating warmth. Parallel shaft gearboxes possess the shortest amount of our inline equipment reducer options therefore they work very well in conditions with limited space. Our parallel shaft equipment reducers offer an affordable drop-in substitute solution for most small parallel shaft gearmotors.
Wormwheel gearboxes go by several names, including 90-degree gearboxes, right position gearboxes, quickness reducers, worm equipment reducers and worm drive gearboxes. Gear reduction boxes include a gear arrangement in which a gear in the form of a screw, also referred to as 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 act like a spur equipment, the worm gearboxes are considerably smaller than other equipment reduction boxes. A major benefit of worm gear reducers is definitely that they generate an output that is 90° from the insight and can be utilized to transmit higher torque or decrease rotational speed. Frequently, a worm gearbox provides right hand threads; to improve the direction of the result, a left-hand thread worm gearbox is required.

GEAR RATIO 10:1
Ever-Power EP series triple-reduction worm gear swiftness reducers can be found in ratios from 5000:1 to 175,000:1 and middle 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 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 mounted.
These reducers are ideal for water/waste-water gear drive applications such as thickeners and clarifiers, which need a vertical straight down shaft. Other available configurations also make Ever-Power triple reduction reducers perfect for use on mixers, elevators, solar power panels, astronomical telescopes, indexing tables, hoists, conveyors, or additional process or materials handling systems where large torques/gradual speeds are needed.
These reducers are also available with a helical main reduction stage and so are termed the HDVM series
Enclosed Gears / Gearboxes
Enclosed gears, also called gearboxes or speed reducers, are open gears within a housing. The casing facilitates bearings and shafts, holds in lubricants, and protects the elements from surrounding circumstances. Gearboxes can be found in an array of load capacities and quickness ratios.
The objective 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 certainly a velocity reducer, the torque result will increase; if the drive increases speed, the torque output will reduce. Gear drive selection factors include: shaft orientation, speed ratio, design type, character of load, gear rating, environment, mounting position, operating temperature range, and lubrication.
Basic Types of Gearboxes
Worm Gear Speed Reducers
A single reduction speed reducer can achieve up to a 100:1 decrease ratio in a little 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 each 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 reduction ratios could be created by using double and triple reduction ratios.
Helical Gear Speed Reducers
Provide high-efficiency speed decrease through 1, 2, 3, or 4 models of gears. Power can be transmitted from a high-swiftness pinion to a slower-speed gear. 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 (input and output shafts are offset). Single-stage helical equipment reducers are usually used for gear ratios up to about 8:1. Where lower speeds and higher ratios are required, double, triple, and quadruple gear reduction stages can be used.
Cycloidal Disc Speed Reducers
Different from conventional gearing because they operate with out a high speed pinion or equipment teeth, and the elements operate in compression instead of shear. This is due to the design of the cycloidal discs that roll within a ring 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) 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 have a hollow output shaft that slips over the driven shaft.
A gearmotor combines a specific 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 input and result shafts to retain essential oil and block dirt. The mostly used 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 use for high-velocity applications, and contain a housing with a series of bands that limit leakage. A breather is usually a connect with a hole that’s mounted in the apparatus housing allowing airflow and relieve internal pressure.
Enclosed gears are generally lubricated with oil. The most typical types of essential oil are rust and oxidation inhibiting, severe pressure, compounded, and synthetic. Other types 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 means of substantially decreasing swiftness 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 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 sector machines, and on rudders. In addition, milling heads and rotary tables sit using high-precision duplex worm drives with adjustable backlash.
