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 input speeds, or when gearmotor efficiency is important. Get in touch with our technical sales staff for help identifying which gearbox answer 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 correct angle gearboxes were created with five mounting choices 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 correct angle planetary gearboxes provide a robust solution. The right angle bevel gearbox will come in 18 ratios ranging from 5:1 to 1000:1, and it is back-drivable at all ratios.

Our 52 frame size can be available with plastic material gears for noise-sensitive applications.
INLINE PLANETARY GEARBOX
inline-planetary-gearbox
Our inline planetary gearbox configurations supply the highest effectiveness and best result torque of most our swiftness reducers. These gearboxes are designed to deal with varying loads with small backlash. Planetary equipment reducers operate more quietly than parallel shaft reducers. With 18 ratio options ranging from 5:1 to 1000:1, we’ve a solution to suit your needs.
PARALLEL SHAFT GEARBOX
parallel-shaft-gearbox
Parallel shaft gearboxes are the top choice for continuous duty applications. Their gear 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 environments with limited space. Our parallel shaft gear reducers offer an affordable drop-in alternative solution for most small parallel shaft gearmotors.
Wormwheel gearboxes pass several names, including 90-degree gearboxes, right angle gearboxes, speed 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 equipment. These gears are usually 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 usually that they produce 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 has right hand threads; to improve the direction of the result, a left-hands thread worm gearbox is required.

Ever-Power EP series triple-reduction worm gear swiftness reducers are available in ratios from 5000:1 to 175,000:1 and center distances from 7” to 20” (larger sizes available on request). Result torque ranges from 33,000 in pounds. 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 installed.

These reducers are ideal for water/waste-water products drive applications such as for example thickeners and clarifiers, which need a vertical straight down shaft. Other available configurations also make Ever-Power triple reduction reducers perfect for use on mixers, elevators, solar panels, astronomical telescopes, indexing tables, hoists, conveyors, or other process or materials handling systems where large torques/sluggish speeds are needed.

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

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

The purpose of a gearbox is to increase or reduce speed. Consequently, torque output would be the inverse of the function. If the enclosed drive is usually a velocity reducer, the torque output will increase; if the drive boosts speed, the torque result will reduce. Gear drive selection elements include: shaft orientation, quickness 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 acceleration reducer can achieve up to a 100:1 reduction ratio in a small package. Known as right angle drives, these contain a cylindrical worm with screw threads and a worm. With an individual begin worm, the worm equipment advances only 1 tooth for every 360-degree change of the worm. So, regardless of 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 decrease ratios.

Helical Gear Speed Reducers
Provide high-efficiency speed decrease through 1, 2, 3, or 4 models of gears. Power is transmitted from a high-velocity 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 (insight and output shafts are in line) and parallel shaft (input and result 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 needed, 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 swiftness pinion or gear teeth, and the elements 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 style. The main components are 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, 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 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 oil and prevent dirt. The most commonly used 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 use for high-speed applications, and consist of a housing with some rings that limit leakage. A breather is certainly a plug 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 worm reduction gearbox styles consist of grease and solid film. Grease can be utilized 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 usually high-speed and low-torque; the addition of a worm drive escalates the range of applications that it might be suitable for, particularly when the worm drive’s compactness is considered.

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