GEARBOX REDUCERS
Correct angle gearboxes (worm and planetary) are durable and built for 90° turns. Inline reducers (parallel shaft and planetary) are a perfect match for motors with high input speeds, or when gearmotor efficiency is important. Contact our technical sales personnel for help determining which gearbox answer is most beneficial for you.

EP’s worm equipment reducers were created with a hollow bore and allow 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 item.

PARALLEL SHAFT GEARBOX
parallel-shaft-gearbox
Parallel shaft gearboxes are the top choice for constant 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 well in conditions with limited space. Our parallel shaft equipment reducers offer an affordable drop-in alternative solution for most little parallel shaft gearmotors.
Wormwheel gearboxes pass several names, including 90-degree gearboxes, right angle gearboxes, acceleration reducers, worm gear reducers and worm drive gearboxes. Gear reduction boxes include a gear arrangement when a equipment in the kind of a screw, also called a worm, meshes with a worm equipment. These gears are typically created from bronze and the worms are metal or stainless steel.

While worm gears are similar to a spur gear, the worm gearboxes are significantly smaller than other gear reduction boxes. A main benefit of worm equipment reducers is usually 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 quickness reducers can be found in ratios from 5000:1 to 175,000:1 and middle 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 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 installed.

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

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

Enclosed Gears / Gearboxes
Enclosed gears, also known as gearboxes or swiftness reducers, are open gears within a housing. The housing supports bearings and shafts, retains in lubricants, and protects the components from surrounding circumstances. Gearboxes can be found in an array of load capacities and swiftness 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 usually a velocity reducer, the torque result 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, working temperature range, and lubrication.

Basic Types of Gearboxes

Worm Gear Speed Reducers
A single reduction swiftness reducer can achieve up to 100:1 decrease ratio in a small package. Referred to as right angle drives, these consist of a cylindrical worm with screw threads and a worm. With an individual begin worm, the worm equipment advances only one tooth for every 360-degree change of the worm. So, regardless of the worm’s size, the gear ratio is the ‘size of the worm equipment to 1′. Higher reduction ratios could 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 units of gears. Power is usually transmitted from a high-velocity pinion to a slower-speed equipment. Helical gears generally operate with their shafts parallel to one another. Both most common types are the concentric (input and result shafts are in line) and parallel shaft (input and result shafts are offset). Single-stage helical equipment reducers are typically used for gear ratios up to about 8:1. Where lower speeds and higher ratios are necessary, 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 velocity pinion or gear teeth, and the components operate in compression instead of shear. This is due to the design of the cycloidal discs that roll within a ring gear housing, comparable to a planetary style. The primary components are the eccentric cam, the internally flanged result 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, that have feet for bolting, are the most common.

Shaft-mounted reducers have a hollow output shaft that slips more than the driven shaft.

A gearmotor combines a specific gearset with a electric 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 your gear housing and insight and output shafts to retain essential oil and prevent dirt. The most commonly utilized type, the radial lip seal, includes a metallic casing that fits in to the casing bore and an elastomeric sealing lip that presses on the shaft. Labyrinth seals are make use of for high-speed applications, and consist of a housing with a series of bands that limit leakage. A breather is usually a plug with a hole that’s mounted in the apparatus housing allowing airflow and relieve internal 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 program and a circulating system
Worm Reduction Gearbox App:

Worm drives certainly are a compact means of substantially decreasing swiftness and increasing torque. Small electric motors are generally high-speed and low-torque; the addition of a worm drive escalates the selection of applications that it may 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 industry machines, and on rudders. Furthermore, milling heads and rotary tables are positioned using high-precision duplex worm drives with adjustable backlash.
