GEARBOX REDUCERS
Right 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 performance is important. Contact our technical sales staff for help identifying which gearbox remedy is best 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 output. 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 choices providing flexibility when incorporating the reducer into item.
RIGHT ANGLE BEVEL GEARBOX
bevel-right-angle-gearbox
The right angle bevel gearbox worm reduction gearbox combines the features of our correct angle worm and planetary inline reducers. With a solid and efficient right angle configuration, our right 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, in fact 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 operation of our rate reducers. These gearboxes are made to deal with varying loads with small backlash. With frame 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 is also available with plastic-type gears for noise-delicate applications.
INLINE PLANETARY GEARBOX
inline-planetary-gearbox
Our inline planetary gearbox configurations provide the highest effectiveness and best output torque of most our acceleration reducers. These gearboxes are created to manage varying loads with small backlash. Planetary gear reducers operate more quietly than parallel shaft reducers. With 18 ratio options ranging from 5:1 to 1000:1, we have a solution to suit your needs.
PARALLEL SHAFT GEARBOX
parallel-shaft-gearbox
Parallel shaft gearboxes are the best choice for constant duty applications. Their equipment cluster design provides a highly effective method for dissipating heat. Parallel shaft gearboxes possess the shortest length 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 pass several names, including 90-degree gearboxes, right position gearboxes, rate reducers, worm gear reducers and worm drive gearboxes. Gear decrease boxes feature a gear arrangement in which a equipment in the type 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 act like a spur equipment, the worm gearboxes are considerably smaller than other equipment reduction boxes. A main benefit of worm equipment reducers is usually that they produce an output that is 90° from the input and can be utilized to transmit higher torque or decrease rotational speed. Most often, a worm gearbox has right hand threads; to change the path of the result, a left-hand thread worm gearbox is required.

Ever-Power EP series triple-reduction worm gear speed reducers can be found 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 pounds 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 are available in four configurations: horizontal, vertical, shafted, and shaft installed.

These reducers are well suited for water/waste-water gear drive applications such as thickeners and clarifiers, which need a vertical down shaft. Other offered 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 materials handling systems where huge torques/gradual speeds are needed.

These reducers are also offered with a helical principal reduction stage and 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 housing supports bearings and shafts, keeps in lubricants, and protects the components from surrounding circumstances. Gearboxes are available in an array of load capacities and acceleration ratios.

The objective of a gearbox is to increase or reduce speed. Consequently, torque output will be the inverse of the function. If the enclosed drive is definitely a quickness reducer, the torque result will increase; if the drive raises speed, the torque output will decrease. Gear drive selection elements include: shaft orientation, swiftness 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 velocity reducer can achieve up to a 100:1 reduction ratio in a little package. Referred to as right angle drives, these contain a cylindrical worm with screw threads and a worm. With an individual begin worm, the worm gear advances only one tooth for every 360-degree turn of the worm. So, whatever the worm’s size, the apparatus ratio may be the ‘size of the worm equipment to 1′. Higher reduction ratios can be created through the use of double and triple reduction ratios.

Helical Gear Speed Reducers
Provide high-efficiency speed reduction through 1, 2, 3, or 4 models of gears. Power is definitely transmitted from a high-speed pinion to a slower-speed gear. Helical gears generally operate with their shafts parallel to one another. The two most common types will be the concentric (insight and output shafts are in range) and parallel shaft (input and result 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 required, dual, triple, and quadruple gear reduction stages may be used.

Cycloidal Disc Speed Reducers
Different from conventional gearing because they operate with out a high swiftness pinion or equipment teeth, and the elements operate in compression rather than shear. This is due to the style of the cycloidal discs that roll within a band gear housing, comparable to a planetary design. The main components will be the eccentric cam, the internally flanged result shaft, the discs, and the ring gear housing.

Three Mounting Options
(L-R) Foundation 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 engine. 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 input and output shafts to retain essential oil and block dirt. The most commonly utilized type, the radial lip seal, includes a metallic casing that fits into the casing bore and an elastomeric sealing lip that presses on the shaft. Labyrinth seals are use for high-quickness applications, and contain a housing with a series of rings that limit leakage. A breather can be a plug with a hole that is mounted in the apparatus housing allowing airflow and relieve internal pressure.

Lubrication
Enclosed gears are generally lubricated with oil. The most common types of oil are rust and oxidation inhibiting, severe pressure, compounded, and synthetic. Other styles include grease and solid film. Grease can be utilized for worm, planetary, cycloidal, and hypoidal reducers. Common distribution methods are a splash program and a circulating system
Worm Reduction Gearbox Application:

Worm drives are a compact method of substantially decreasing rate and increasing torque. Small electric motors are generally 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 known as.

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 are positioned using high-precision duplex worm drives with adjustable backlash.
