GEARBOX REDUCERS
Correct angle gearboxes (worm and planetary) are tough and built for 90° turns. Inline reducers (parallel shaft and planetary) are a perfect match for motors with high input speeds, or when gearmotor performance is important. Contact our technical sales staff for help identifying which gearbox solution is most beneficial for you.
RIGHT ANGLE REDUCERS

EP’s worm equipment reducers are designed with a hollow bore and invite for a corner turn with optional dual result. The reducers can be found in 12 ratios ranging from 5:1 to 100:1, with non-back-drivable ratios 30:1 and higher. Our right angle gearboxes were created with five mounting options providing flexibility when incorporating the reducer into product.

PARALLEL SHAFT GEARBOX
parallel-shaft-gearbox
Parallel shaft gearboxes will be the top choice for constant duty applications. Their gear cluster design provides a highly effective method for dissipating heat. Parallel shaft gearboxes possess the shortest length of our inline gear reducer options so they work well in environments with limited space. Our parallel shaft equipment reducers offer 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, quickness reducers, worm equipment reducers and worm drive gearboxes. Gear reduction boxes feature a gear arrangement in which a gear in the type of a screw, also referred to as a worm, meshes with a worm equipment. These gears are typically made from bronze and the worms are steel 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 gear reducers is certainly that they generate an output that is 90° from the input and can be used to transmit higher torque or decrease rotational speed. Most often, a worm gearbox provides right hand threads; to improve the direction of the output, a left-hands thread worm gearbox is required.

Ever-Power EP series triple-reduction worm gear speed reducers can be found 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 lbs. for the 7” CD EP-70 to 582,900 in pounds for the EP-200. Mechanical HP insight 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 gear drive applications such as for example thickeners and clarifiers, which need a vertical straight down shaft. Other available configurations also make Ever-Power triple decrease reducers perfect for use on mixers, elevators, solar power panels, astronomical telescopes, indexing tables, hoists, conveyors, or additional process or components handling systems where huge torques/slow speeds are needed.

These reducers are also offered with a helical main 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 conditions. Gearboxes can be found in a wide range of load capacities and velocity ratios.

The purpose of a gearbox is to increase or reduce speed. Because of this, torque output will be the inverse of the function. If the enclosed drive is certainly a acceleration reducer, the torque output will increase; if the drive boosts speed, the torque output will decrease. Gear drive selection elements include: shaft orientation, swiftness ratio, design type, nature of load, gear rating, environment, mounting position, operating temperature range, and lubrication.

Basic Types of Gearboxes

Worm Gear Speed Reducers
A single reduction quickness reducer can achieve up to a 100:1 decrease ratio in a small package. Known as right angle drives, these consist of a cylindrical worm with screw threads and a worm. With a single 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 gear to 1′. Higher decrease ratios could 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 units of gears. Power is certainly transmitted from a high-quickness pinion to a slower-speed gear. Helical gears usually operate with their shafts parallel to each other. 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 gear reducers are usually used for equipment ratios up to about 8:1. Where decrease speeds and higher ratios are necessary, double, triple, and quadruple gear reduction stages can be used.

Cycloidal Disc Speed Reducers
Different from conventional gearing because they operate without a high velocity pinion or equipment teeth, and the parts operate in compression instead of shear. This is because of the design of the cycloidal discs that roll within a ring gear housing, similar to a planetary style. The primary components will be 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 an enclosed gearset with a motor. A motorized reducer resembles a gearmotor except that it’s driven by a separate NEMA C-face motor.

Seals and Breathers
Seals are used between the gear housing and insight and output shafts to retain essential oil and block dirt. The most commonly 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 make use of for high-velocity applications, and contain a housing with a series of rings that limit leakage. A breather is certainly a plug with a hole that’s mounted in the apparatus housing to permit airflow and relieve inner pressure.

Lubrication
Enclosed gears are generally lubricated with oil. The most typical types of essential oil are rust and oxidation inhibiting, extreme pressure, compounded, and synthetic. Other types consist of grease and solid film. Grease can be used for worm, planetary, cycloidal, and hypoidal reducers. Common distribution methods are a splash system and a circulating system
Worm Reduction Gearbox Application:

Worm drives certainly are a compact method of substantially decreasing quickness and increasing torque. Little electric motors are generally high-speed and low-torque; the addition of a worm drive increases the selection of applications that it could be suitable for, particularly when the worm drive’s compactness is known as.

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