GEARBOX REDUCERS
Right angle gearboxes (worm and planetary) are durable and built for 90° turns. Inline reducers (parallel shaft and planetary) are an ideal match for motors with high insight speeds, or when gearmotor efficiency is important. Contact our technical sales personnel for help determining which gearbox solution is best for you.
RIGHT ANGLE REDUCERS
WORM GEAR REDUCER
EP’s worm gear reducers are designed with a hollow bore and allow for a corner convert with optional dual output. 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 choices providing flexibility when incorporating the reducer into product.

These gearboxes are created to manage varying loads with little backlash. Planetary equipment reducers operate more quietly than parallel shaft reducers. With 18 ratio choices which range from 5:1 to 1000:1, we’ve a solution to fit your needs.
PARALLEL SHAFT GEARBOX
worm reduction gearbox parallel-shaft-gearbox
Parallel shaft gearboxes are the best choice for constant duty applications. Their gear cluster design provides an effective method for dissipating warmth. Parallel shaft gearboxes possess 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 little parallel shaft gearmotors.
Wormwheel gearboxes go by several names, including 90-degree gearboxes, right position gearboxes, rate reducers, worm equipment reducers and worm drive gearboxes. Gear decrease boxes include a gear arrangement in which a equipment in the type of a screw, also called a worm, meshes with a worm equipment. These gears are usually created from bronze and the worms are metal or stainless steel.

While worm gears are similar to a spur gear, the worm gearboxes are considerably smaller than other equipment reduction boxes. A primary benefit of worm equipment reducers is that they generate an output that is 90° from the insight and can be utilized to transmit higher torque or decrease rotational speed. Frequently, a worm gearbox offers right hand threads; to improve the path of the output, a left-hands thread worm gearbox is required.

Ever-Power EP series triple-reduction worm gear swiftness 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 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 mounted.

These reducers are well suited for water/waste-water devices 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 make use of 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 offered with a helical primary reduction stage and so are termed the HDVM series

Enclosed Gears / Gearboxes
Enclosed gears, also referred to as gearboxes or acceleration reducers, are open gears contained in a housing. The casing supports bearings and shafts, keeps in lubricants, and protects the elements from surrounding conditions. Gearboxes can be found in a wide variety of load capacities and acceleration ratios.

The purpose of a gearbox is to improve or reduce speed. Because of this, torque output would be the inverse of the function. If the enclosed drive is a quickness reducer, the torque output increase; if the drive raises speed, the torque output will decrease. Gear drive selection elements include: shaft orientation, acceleration ratio, design type, character of load, gear rating, 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 100:1 decrease ratio in a small package. Referred to as right position drives, these consist of a cylindrical worm with screw threads and a worm. With an individual begin worm, the worm gear advances only 1 tooth for every 360-degree turn of the worm. So, regardless of the worm’s size, the gear ratio may be the ‘size of the worm equipment to 1′. Higher decrease ratios can be created through the use of double and triple decrease ratios.

Helical Gear Speed Reducers
Provide high-efficiency speed reduction through 1, 2, 3, or 4 sets of gears. Power is transmitted from a high-quickness pinion to a slower-speed gear. Helical gears generally operate with their shafts parallel to one another. The two most common types will be the concentric (input and output shafts are in series) and parallel shaft (input and output shafts are offset). Single-stage helical equipment reducers are usually used for gear ratios up to about 8:1. Where cheaper speeds and higher ratios are needed, double, triple, and quadruple equipment reduction stages may be used.

Cycloidal Disc Speed Reducers
Different from conventional gearing because they operate with out a high speed pinion or equipment teeth, and the elements operate in compression rather than shear. This is because of the design of the cycloidal discs that roll within a ring gear housing, similar to a planetary design. The primary components are the eccentric cam, the internally flanged result 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, will be the most common.

Shaft-mounted reducers have a hollow output shaft that slips more than 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 your gear housing and insight and output shafts to retain essential oil and prevent dirt. The mostly utilized type, the radial lip seal, consists of a metallic casing that fits into the housing bore and an elastomeric sealing lip that presses on the shaft. Labyrinth seals are use for high-quickness applications, and consist of a housing with a series of bands that limit leakage. A breather is a plug with a hole that is mounted in the gear housing to permit airflow and relieve internal pressure.

Lubrication
Enclosed gears are usually lubricated with oil. The most common types of essential oil are rust and oxidation inhibiting, intense pressure, compounded, and synthetic. Other types include 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 certainly are a compact means of substantially decreasing rate and increasing torque. Little electric motors are usually high-speed and low-torque; the addition of a worm drive escalates the selection of applications that it could be suitable for, particularly when the worm drive’s compactness is known as.

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