GEARBOX REDUCERS
Correct angle gearboxes (worm and planetary) are tough and built for 90° turns. Inline reducers (worm reduction gearbox parallel shaft and planetary) are an ideal match for motors with high input speeds, or when gearmotor performance is important. Contact our technical sales personnel for help identifying which gearbox answer 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 right angle gearboxes were created with five mounting choices providing flexibility when incorporating the reducer into product.
RIGHT ANGLE BEVEL GEARBOX
bevel-right-angle-gearbox
The proper angle bevel gearbox combines the features of our right angle worm and planetary inline reducers. With a solid and efficient correct angle configuration, our correct angle planetary gearboxes offer a robust solution. The proper angle bevel gearbox comes in 18 ratios which range from 5:1 to 1000:1, and it is back-drivable at all ratios.

INLINE PLANETARY GEARBOX
inline-planetary-gearbox
Our inline planetary gearbox configurations provide the highest effectiveness and best output torque of all our acceleration reducers. These gearboxes are created to manage varying loads with little 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 top choice for continuous duty applications. Their gear cluster design provides a highly effective method for dissipating warmth. Parallel shaft gearboxes have the shortest length of our inline equipment reducer options so they work well in conditions with limited space. Our parallel shaft equipment 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, velocity reducers, worm equipment reducers and worm drive gearboxes. Gear reduction boxes feature a gear arrangement when a equipment in the type 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 gear, the worm gearboxes are significantly smaller than other gear reduction boxes. A primary benefit of worm gear reducers is usually that they produce an output that’s 90° from the input and can be utilized to transmit higher torque or decrease rotational speed. Frequently, a worm gearbox provides right hand threads; to change the direction of the result, a left-hands thread worm gearbox is necessary.

These reducers are also available with a helical main reduction stage and are termed the HDVM series

Enclosed Gears / Gearboxes
Enclosed gears, also called gearboxes or speed reducers, are open gears contained in a housing. The casing facilitates bearings and shafts, keeps in lubricants, and protects the parts from surrounding circumstances. Gearboxes can be found in a wide range of load capacities and rate ratios.

The objective of a gearbox is to increase or reduce speed. As a result, torque output will be the inverse of the function. If the enclosed drive is usually a acceleration reducer, the torque result will increase; if the drive increases speed, the torque output will decrease. Gear drive selection elements include: shaft orientation, speed 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 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 an individual start worm, the worm equipment advances only one tooth for every 360-degree change 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 by using 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-acceleration pinion to a slower-speed equipment. Helical gears generally operate with their shafts parallel to each other. Both most common types will be the concentric (insight and output shafts are in series) 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 reduced speeds and higher ratios are needed, double, triple, and quadruple equipment reduction stages may be used.

Cycloidal Disc Speed Reducers
Not the same as conventional gearing because they operate without a high quickness pinion or gear teeth, and the elements operate in compression rather than shear. This is due to the design of the cycloidal discs that roll within a ring gear housing, comparable to a planetary style. The main components are the eccentric cam, the internally flanged output shaft, the discs, and the ring gear casing.

Three Mounting Options
(L-R) Foundation 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 engine. 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 prevent dirt. The mostly utilized type, the radial lip seal, includes a steel casing that fits in to the casing bore and an elastomeric sealing lip that presses on the shaft. Labyrinth seals are use for high-speed applications, and contain a housing with a series of bands that limit leakage. A breather is definitely 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, severe pressure, compounded, and synthetic. Other types consist of grease and solid film. Grease can be utilized for worm, planetary, cycloidal, and hypoidal reducers. Common distribution methods are a splash system and a circulating system
Worm Reduction Gearbox Program:

Worm drives are a compact means of substantially decreasing speed 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 may 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 machines, and on rudders. In addition, milling heads and rotary tables are positioned using high-precision duplex worm drives with adjustable backlash.
