GEARBOX REDUCERS
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 efficiency is important. Contact our technical sales staff for help identifying which gearbox answer 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 switch with optional dual result. The reducers come in 12 ratios which range from 5:1 to 100:1, with non-back-drivable ratios 30:1 and higher. Our right angle gearboxes were created 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 solid and efficient correct 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, 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 quickness reducers. These gearboxes are made to handle varying loads with small backlash. With body sizes 52cm, 62cm, and 81cm, 12 ratios which range from 5:1 to 308:1, we’ve a solution to suit 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 effectiveness and best output torque of most our velocity reducers. These gearboxes are designed to handle 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 continuous duty applications. Their equipment cluster design provides a highly effective method for dissipating temperature. Parallel shaft gearboxes have the shortest amount of our inline equipment reducer options so they work very well in conditions with limited space. Our parallel shaft equipment reducers offer an affordable drop-in replacement solution for most small parallel shaft gearmotors.
Wormwheel gearboxes pass several names, including 90-degree gearboxes, right position gearboxes, velocity reducers, worm gear reducers and worm drive gearboxes. Gear reduction boxes feature a gear arrangement in which a gear in the kind of a screw, also called 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 are similar to a spur equipment, the worm gearboxes are significantly smaller than other gear reduction boxes. A primary benefit of worm gear reducers is usually 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 change the path of the result, a left-hand thread worm gearbox is required.

Ever-Power EP series triple-reduction worm gear velocity reducers can be found 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 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 tools drive applications such as thickeners and clarifiers, which need a vertical down shaft. Other available configurations also make Ever-Power triple decrease reducers perfect for use on mixers, elevators, solar power panels, astronomical telescopes, indexing tables, hoists, conveyors, or additional process or components handling systems where large torques/slower speeds are needed.

These reducers are also offered with a helical major reduction stage and are termed the HDVM series

Enclosed Gears / Gearboxes
Enclosed gears, also referred to as gearboxes or rate reducers, are open gears within a housing. The housing supports bearings and shafts, holds in lubricants, and protects the components from surrounding circumstances. Gearboxes can be found in a wide variety of load capacities and speed ratios.

The purpose of a gearbox is to improve or reduce speed. Consequently, torque output will be the inverse of the function. If the enclosed drive is usually a quickness reducer, the torque output will increase; if the drive boosts speed, the torque output will reduce. Gear drive selection factors include: shaft orientation, speed ratio, design type, nature of load, gear rating, environment, mounting position, working temperature range, and lubrication.

Basic Types of Gearboxes

Worm Gear Speed Reducers
A single reduction swiftness reducer can achieve up to 100:1 reduction ratio in a little package. Referred to as right angle drives, these consist of a cylindrical worm with screw threads and a worm. With a single begin worm, the worm gear advances only 1 tooth for each 360-degree change of the worm. So, whatever the worm’s size, the gear ratio is the ‘size of the worm equipment 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 models of gears. Power can be transmitted from a high-velocity pinion to a slower-speed gear. Helical gears generally operate with their shafts parallel to each other. Both most common types are the concentric (insight and result shafts are in collection) and parallel shaft (insight and output shafts are offset). Single-stage helical gear reducers are typically used for gear ratios up to about 8:1. Where reduced speeds and higher ratios are required, double, triple, and quadruple gear reduction stages can be used.

Cycloidal Disc Speed Reducers
Not the same as conventional gearing because they operate with out a high velocity pinion or gear 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 casing.

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 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 another NEMA C-face motor.

Seals and Breathers
Seals are used between the gear housing and input and output shafts to retain oil and block dirt. The most commonly utilized type, the radial lip seal, consists of a metallic casing that fits in to the housing bore and an elastomeric sealing lip that presses on the shaft. Labyrinth seals are use for high-rate applications, and consist of a housing with a series of rings that limit leakage. A breather is definitely a plug with a hole that is mounted in the apparatus housing allowing airflow and relieve internal pressure.

Lubrication
Enclosed gears are usually lubricated with oil. The most typical types of oil are rust and oxidation inhibiting, severe pressure, compounded, and synthetic. Other types consist of 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 rate and increasing torque. Little 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 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 are positioned using high-precision duplex worm drives with adjustable backlash.
