GEARBOX REDUCERS
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 efficiency is important. Get in touch with our technical sales staff for help identifying which gearbox solution 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 switch with optional dual output. 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 are designed with five mounting options providing versatility when incorporating the reducer into item.
RIGHT ANGLE BEVEL GEARBOX
bevel-right-angle-gearbox
The right angle bevel gearbox combines the features of our right angle worm and planetary inline reducers. With a good and efficient correct angle configuration, our right angle planetary gearboxes offer 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.
INLINE REDUCERS
I-SERIES PLANETARY GEARBOX
i-series-planetary-gearbox
Our I-Series small planetary gearbox configurations supply the smallest footprint and quietest procedure of our swiftness reducers. These gearboxes are created to deal with varying loads with small backlash. With body sizes 52cm, 62cm, and 81cm, 12 ratios which range from 5:1 to 308:1, we have a solution to suit your needs. Our 52 frame size can be available with plastic-type material gears for noise-delicate applications.
INLINE PLANETARY GEARBOX
inline-planetary-gearbox
Our inline planetary gearbox configurations supply the highest performance and best output torque of most our velocity reducers. These gearboxes are designed to deal with varying loads with small 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 fit your needs.
PARALLEL SHAFT GEARBOX
parallel-shaft-gearbox
Parallel shaft gearboxes will be the best choice for constant duty applications. Their equipment cluster design provides an effective method for dissipating warmth. Parallel shaft gearboxes possess the shortest length of our inline gear reducer options so they work very well in conditions 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, rate reducers, worm gear reducers and worm drive gearboxes. Gear reduction boxes feature a gear arrangement in which 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 steel or stainless steel.
While worm gears act like a spur gear, the worm gearboxes are considerably smaller than other gear reduction boxes. A main benefit of worm equipment reducers is certainly that they create an output that is 90° from the input and can be used to transmit higher torque or reduce rotational speed. Most often, a worm gearbox provides 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 swiftness reducers are available in ratios from 5000:1 to 175,000:1 and middle distances from 7” to 20” (larger sizes on request). Output 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 can be found in four configurations: horizontal, vertical, shafted, and shaft mounted.
These reducers are ideal for water/waste-water equipment drive applications such as thickeners and clarifiers, which require a vertical down shaft. Other offered configurations also make Ever-Power triple reduction reducers perfect for make use of on mixers, elevators, solar power panels, astronomical telescopes, indexing tables, hoists, conveyors, or various other process or components handling systems where huge torques/sluggish speeds are needed.
These reducers are also offered with a helical major reduction stage and so are termed the HDVM series
Enclosed Gears / Gearboxes
Enclosed gears, also known as gearboxes or quickness reducers, are open gears within a housing. The casing supports bearings and shafts, keeps in lubricants, and protects the elements from surrounding circumstances. Gearboxes can be found in an array of load capacities and rate ratios.
The purpose of a gearbox is to increase or reduce speed. Consequently, torque output will be the inverse of the function. If the enclosed drive is a velocity reducer, the torque result will increase; if the drive increases speed, the torque output will decrease. Gear drive selection factors include: shaft orientation, velocity 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 acceleration reducer can achieve up to a 100:1 reduction ratio in a little package. Known as right angle drives, these contain a cylindrical worm with screw threads and a worm. With an individual start worm, the worm equipment advances only one tooth for each 360-degree switch of the worm. So, whatever the worm's size, the apparatus ratio is the ‘size of the worm gear to 1′. Higher reduction ratios can be created by using double and triple decrease ratios.
Helical Gear Speed Reducers
Provide high-efficiency speed reduction through 1, 2, 3, or 4 units of gears. Power is usually transmitted from a high-swiftness pinion to a slower-speed equipment. Helical gears usually operate with their shafts parallel to one another. Both most common types will be the concentric (insight and result 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 reduce speeds and higher ratios are necessary, dual, triple, and quadruple equipment reduction stages may be used.
Cycloidal Disc Speed Reducers
Different from conventional gearing because they operate without a high quickness pinion or equipment teeth, and the elements operate in compression instead of shear. This is because of the style of the cycloidal discs that roll within a ring gear housing, similar to a planetary style. The main components are the eccentric cam, the internally flanged output shaft, the discs, and the ring gear casing.
Three Mounting Options
(L-R) Bottom Mounted, Shaft-Mounted, Gearmotor
(L-R) Base-Mounted, Shaft-Mounted, Gearmotor
Base-mounted reducers, that have feet for bolting, will be the most common.
Shaft-mounted reducers have 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's driven by another NEMA C-face motor.
Seals and Breathers
Seals are used between the gear housing and insight and result shafts to retain essential oil and prevent dirt. The mostly utilized type, the radial lip seal, consists of a metal casing that fits in to the casing bore and an elastomeric sealing lip that presses on the shaft. Labyrinth seals are use for high-swiftness applications, and consist of a housing with some rings that limit leakage. A breather is definitely a plug with a hole that's mounted in the apparatus housing allowing airflow and relieve internal pressure.
Lubrication
Enclosed gears are usually lubricated with oil. The most common types of essential oil are rust and oxidation inhibiting, extreme pressure, compounded, and synthetic. Other types 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 Application:
Worm drives are a compact means of substantially decreasing swiftness and increasing torque. Little electric motors are generally high-speed and low-torque; the addition of a worm drive increases the selection of applications that it could be suitable for, particularly when the worm drive's compactness is considered.
Worm drives are used in presses, in rolling mills, in conveying engineering, in mining sector devices, and on rudders. Furthermore, milling heads and rotary tables sit using high-precision duplex worm drives with adjustable backlash.
