GEARBOX REDUCERS
Right angle gearboxes (worm and planetary) are tough and built for 90° turns. Inline reducers (parallel shaft and planetary) are a perfect match for motors with high insight speeds, or when gearmotor performance is important. Contact our technical sales personnel for help determining which gearbox solution is most beneficial for you.
RIGHT ANGLE REDUCERS
WORM GEAR REDUCER
EP’s worm equipment reducers are designed with a hollow bore and invite for a corner convert 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 were created with five mounting options providing versatility when incorporating the reducer into product.
RIGHT ANGLE BEVEL GEARBOX
bevel-right-angle-gearbox
The right angle bevel gearbox combines the top features of our correct angle worm and planetary inline reducers. With a good and efficient correct angle configuration, our correct angle planetary gearboxes offer 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.
INLINE REDUCERS
I-SERIES PLANETARY GEARBOX
i-series-planetary-gearbox
Our I-Series small planetary gearbox configurations provide the smallest footprint and quietest procedure of our rate reducers. These gearboxes are designed to handle varying loads with little backlash. With body 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 is also available with plastic-type material gears for noise-delicate applications.
INLINE PLANETARY GEARBOX
inline-planetary-gearbox
Our inline planetary gearbox configurations provide the highest efficiency and best result torque of all our rate reducers. These gearboxes are made 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 will be the best choice for constant duty applications. Their equipment cluster design provides a highly effective method for dissipating heat. Parallel shaft gearboxes have the shortest length of our inline gear reducer options therefore they work very well in conditions with limited space. Our parallel shaft gear reducers provide an affordable drop-in replacement solution for most small 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 decrease boxes feature a gear arrangement when a equipment in the form of a screw, also called a worm, meshes with a worm equipment. These gears are typically created from bronze and the worms are steel or stainless steel.

While worm gears act like a spur equipment, the worm gearboxes are significantly smaller than other equipment reduction boxes. A primary benefit of worm gear reducers is definitely that they produce an output that’s 90° from the input and can be used to transmit higher torque or decrease rotational speed. Most often, a worm gearbox provides right hand threads; to change the direction of the output, a left-hand thread worm gearbox is necessary.

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 available 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 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 equipment drive applications such as for example thickeners and clarifiers, which require a vertical down shaft. Other obtainable configurations also make Ever-Power triple decrease reducers perfect for use on mixers, elevators, solar panels, astronomical telescopes, indexing tables, hoists, conveyors, or other process or worm reduction gearbox materials handling systems where huge torques/slower 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 called gearboxes or quickness reducers, are open gears contained in a housing. The casing supports bearings and shafts, holds in lubricants, and protects the components from surrounding conditions. Gearboxes are available in a wide selection of load capacities and acceleration 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 usually a rate reducer, the torque result increase; if the drive improves speed, the torque output will decrease. Gear drive selection elements include: shaft orientation, quickness ratio, design type, character of load, gear ranking, 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 decrease ratio in a little package. Referred to as right position drives, these contain a cylindrical worm with screw threads and a worm. With a single start worm, the worm gear advances only 1 tooth for every 360-degree turn 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 can be created by using double and triple decrease ratios.

Helical Gear Speed Reducers
Provide high-efficiency speed decrease through 1, 2, 3, or 4 units of gears. Power is certainly transmitted from a high-acceleration 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 (input and output shafts are in range) and parallel shaft (input and output shafts are offset). Single-stage helical equipment reducers are typically used for equipment ratios up to about 8:1. Where reduce speeds and higher ratios are needed, dual, triple, and quadruple equipment reduction stages may be used.

Cycloidal Disc Speed Reducers
Different from conventional gearing because they operate with out a high swiftness pinion or gear teeth, and the parts operate in compression rather than shear. This is due to the design 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 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 motor. A motorized reducer resembles a gearmotor except that it is driven by another NEMA C-face motor.

Seals and Breathers
Seals are used between your gear housing and insight and result shafts to retain essential oil and prevent dirt. The most commonly utilized type, the radial lip seal, consists of a metallic casing that fits into the casing bore and an elastomeric sealing lip that presses on the shaft. Labyrinth seals are make use of for high-quickness applications, and contain a housing with a series of bands that limit leakage. A breather is usually a plug with a hole that’s mounted in the apparatus housing to permit airflow and relieve inner pressure.

Lubrication
Enclosed gears are usually lubricated with oil. The most common types of oil are rust and oxidation inhibiting, intense pressure, compounded, and synthetic. Other styles consist of grease and solid film. Grease can be used for worm, planetary, cycloidal, and hypoidal reducers. Common distribution strategies are a splash system and a circulating system
Worm Reduction Gearbox Software:

Worm drives certainly are a compact method of substantially decreasing quickness and increasing torque. Little electric motors are usually high-speed and low-torque; the addition of a worm drive increases the selection of applications that it could be suitable for, specially 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. In addition, milling heads and rotary tables are positioned using high-precision duplex worm drives with adjustable backlash.
