GEARBOX REDUCERS
Right 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 performance is important. Get in touch with our technical sales personnel for help identifying which gearbox alternative is most beneficial for you.
RIGHT ANGLE REDUCERS
WORM GEAR REDUCER
EP’s worm gear reducers are designed with a hollow bore and allow for a corner turn 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 options providing flexibility when incorporating the reducer into product.
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 right angle configuration, our correct angle planetary gearboxes provide a robust solution. The right angle bevel gearbox comes in 18 ratios which range from 5:1 to 1000:1, and it is back-drivable at all ratios.
INLINE REDUCERS

These gearboxes are made to handle varying loads with little backlash. With frame sizes 52cm, 62cm, and 81cm, 12 ratios ranging from 5:1 to 308:1, we have a solution to suit your needs. Our 52 frame size is also available with plastic 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 all our rate reducers. These gearboxes are made to deal with 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 fit your needs.
PARALLEL SHAFT GEARBOX
parallel-shaft-gearbox
Parallel shaft gearboxes will be the best choice for constant duty applications. Their gear cluster design provides an effective method for dissipating warmth. Parallel shaft gearboxes have the shortest length of our inline gear reducer options so they work well in conditions with limited space. Our parallel shaft gear reducers provide an affordable drop-in alternative solution for most small parallel shaft gearmotors.
Wormwheel gearboxes go by several names, including 90-degree gearboxes, right angle gearboxes, acceleration reducers, worm gear reducers and worm drive gearboxes. Gear decrease boxes include a gear arrangement in which a gear in the type of a screw, also called 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 are similar to a spur gear, the worm gearboxes are significantly smaller than other equipment reduction boxes. A principal benefit of worm equipment reducers is definitely that they generate an output that’s 90° from the insight and can be used to transmit higher torque or decrease rotational speed. Most often, a worm gearbox has right hand threads; to change the path of the output, a left-hands thread worm gearbox is necessary.

Ever-Power EP series triple-reduction worm gear acceleration 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 lbs. for the 7” CD EP-70 to 582,900 in lbs 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 products drive applications such as for example thickeners and clarifiers, which need a vertical down shaft. Other offered configurations also make Ever-Power triple reduction reducers perfect for use on mixers, elevators, solar power panels, astronomical telescopes, indexing tables, hoists, conveyors, or various other process or materials handling systems where huge torques/slower speeds are needed.

These reducers are also obtainable with a helical principal reduction stage and so are termed the HDVM series

Enclosed Gears / Gearboxes
Enclosed gears, also called gearboxes or acceleration reducers, are open gears contained in a housing. The housing facilitates bearings and shafts, holds in lubricants, and protects the components from surrounding circumstances. Gearboxes are available in a wide variety of load capacities and velocity ratios.

The purpose of a gearbox is to improve or reduce speed. Consequently, torque output would be the inverse of the function. If the enclosed drive is definitely a swiftness reducer, the torque result will increase; if the drive boosts speed, the torque output will decrease. Gear drive selection factors include: shaft orientation, rate ratio, design type, nature of load, gear ranking, 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 small package. Referred to as right angle drives, these contain a cylindrical worm with screw threads and a worm. With a single start worm, the worm gear advances only one tooth for each 360-degree convert of the worm. So, whatever the worm’s size, the apparatus ratio may be 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 reduction through 1, 2, 3, or 4 pieces of gears. Power is certainly transmitted from a high-quickness pinion to a slower-speed equipment. Helical gears usually operate with their shafts parallel to one another. The two most common types are the concentric (insight and result shafts are in line) and parallel shaft (insight and result shafts are offset). Single-stage helical gear reducers are typically used for equipment ratios up to about 8:1. Where cheaper speeds and higher ratios are necessary, double, triple, and quadruple equipment reduction stages can be used.

Cycloidal Disc Speed Reducers
Different from conventional gearing because they operate with out a high acceleration pinion or equipment teeth, and the parts operate in compression instead of 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) 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 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 input and output shafts to retain essential oil and block dirt. The most commonly utilized type, the radial lip seal, includes a metal casing that fits into 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 some bands that limit leakage. A breather is definitely a connect with a hole that’s mounted in the gear housing to permit airflow and relieve internal pressure.

Lubrication
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 used for worm, planetary, cycloidal, and hypoidal reducers. Common distribution methods are a splash system and a circulating system
Worm Reduction Gearbox Application:

Worm drives 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 escalates the range of applications that it might be suitable for, specially when the worm drive’s compactness is considered.

Worm drives are found in presses, in rolling mills, in conveying engineering, in mining industry devices, and on rudders. In addition, milling heads and rotary tables sit using high-precision duplex worm drives with adjustable backlash.
