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 insight speeds, or when gearmotor performance is important. Contact our technical sales personnel for help identifying which gearbox remedy is most beneficial for you.
RIGHT ANGLE REDUCERS
WORM GEAR REDUCER
EP’s worm gear reducers were created with a hollow bore and allow for a corner change with optional dual output. The reducers come in 12 ratios ranging 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 item.

Planetary gear 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
parallel-shaft-gearbox
Parallel shaft gearboxes will be the best choice for continuous duty applications. Their equipment cluster design provides a highly effective method for dissipating temperature. Parallel shaft gearboxes possess the shortest length of our inline equipment reducer options therefore they work very well in environments 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 position gearboxes, acceleration reducers, worm gear reducers and worm drive gearboxes. Gear reduction boxes include a gear arrangement when a gear in the type of a screw, also referred to as a worm, meshes with a worm gear. These gears are typically made 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 main benefit of worm gear reducers is certainly that they produce an output that’s 90° from the insight and can be used to transmit higher torque or reduce rotational speed. Frequently, a worm gearbox offers right hand threads; to improve the path of the result, a left-hands thread worm gearbox is necessary.

Ever-Power EP series triple-reduction worm gear quickness reducers are available 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 are available in four configurations: horizontal, vertical, shafted, and shaft installed.

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

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

Enclosed Gears / Gearboxes
Enclosed gears, also called gearboxes or quickness reducers, are open gears contained in a housing. The housing supports bearings and shafts, retains in lubricants, and protects the parts from surrounding conditions. Gearboxes are available in an array of load capacities and velocity ratios.

The purpose of a gearbox is to increase or reduce speed. As a result, torque output would be the inverse of the function. If the enclosed drive is a speed reducer, the torque output will increase; if the drive boosts speed, the torque result will reduce. Gear drive selection factors include: shaft orientation, swiftness 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 speed reducer can achieve up to 100:1 reduction ratio in a little package. Referred to as right angle 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 turn of the worm. So, whatever the worm’s size, the gear ratio may be the ‘size of the worm equipment to 1′. Higher reduction ratios can be created through the use of double and triple reduction ratios.

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

Cycloidal Disc Speed Reducers
Not the same as conventional gearing because they operate with out a high acceleration pinion or gear teeth, and the components operate in compression instead of shear. This is because of the style of the cycloidal discs that roll within a ring gear housing, similar to a planetary design. 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, 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 an enclosed gearset with a motor. A motorized reducer resembles a gearmotor except that it is driven by a separate NEMA C-face motor.

Seals and Breathers
Seals are used between the gear housing and insight and result shafts to retain oil and block dirt. The most commonly used type, the radial lip seal, consists of a metal casing that fits in to the housing bore and an elastomeric sealing lip that presses on the shaft. Labyrinth seals are use for high-quickness applications, and contain a housing with a series of bands that limit leakage. A breather is certainly a plug with a hole that’s mounted in the gear housing allowing airflow and relieve internal pressure.

Lubrication
Enclosed gears are generally lubricated with oil. The most common types of oil are rust and oxidation inhibiting, extreme 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 worm reduction gearbox splash program and a circulating system
Worm Reduction Gearbox App:

Worm drives certainly are a compact method of substantially decreasing velocity and increasing torque. Small electric motors are usually high-speed and low-torque; the addition of a worm drive escalates the selection of applications that it might be suitable for, specially when the worm drive’s compactness is known as.

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