GEARBOX REDUCERS
Right angle gearboxes (worm and planetary) are tough and built for 90° turns. Inline reducers (worm reduction gearbox parallel shaft and planetary) are a perfect match for motors with high insight speeds, or when gearmotor efficiency is important. Get in touch with our technical sales staff for help identifying which gearbox option is best for you.
RIGHT ANGLE REDUCERS
WORM GEAR REDUCER
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 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 options providing versatility when incorporating the reducer into product.

These gearboxes are designed to deal with varying loads with little backlash. Planetary equipment reducers operate more quietly than parallel shaft reducers. With 18 ratio choices ranging from 5:1 to 1000:1, we’ve a solution to suit your needs.
PARALLEL SHAFT GEARBOX
parallel-shaft-gearbox
Parallel shaft gearboxes are the best choice for continuous duty applications. Their gear cluster design provides an effective method for dissipating high temperature. Parallel shaft gearboxes have the shortest amount of our inline equipment reducer options so they work very well in conditions with limited space. Our parallel shaft gear reducers offer an affordable drop-in replacement solution for most little parallel shaft gearmotors.
Wormwheel gearboxes pass several names, including 90-degree gearboxes, right angle gearboxes, quickness reducers, worm gear reducers and worm drive gearboxes. Gear decrease boxes feature a gear arrangement in which a equipment in the form of a screw, also called a worm, meshes with a worm gear. These gears are typically created from bronze and the worms are metal or stainless steel.

While worm gears are similar to a spur equipment, the worm gearboxes are significantly smaller than other equipment reduction boxes. A primary benefit of worm equipment reducers is definitely that they create an output that is 90° from the insight and can be utilized to transmit higher torque or decrease rotational speed. Frequently, a worm gearbox has right hand threads; to change the direction of the output, a left-hand thread worm gearbox is necessary.

Ever-Power EP series triple-reduction worm gear acceleration 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 pounds. for the 7” CD EP-70 to 582,900 in lbs 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 mounted.

These reducers are well suited for water/waste-water products drive applications such as for example thickeners and clarifiers, which require a vertical straight down shaft. Other available configurations also make Ever-Power triple reduction reducers perfect for use on mixers, elevators, solar power panels, astronomical telescopes, indexing tables, hoists, conveyors, or additional process or components handling systems where large torques/slower speeds are needed.

These reducers are also offered with a helical major reduction stage and so are termed the HDVM series

Enclosed Gears / Gearboxes
Enclosed gears, also known as gearboxes or acceleration reducers, are open gears within a housing. The casing facilitates bearings and shafts, keeps in lubricants, and protects the components from surrounding circumstances. Gearboxes can be found in a wide variety of load capacities and acceleration ratios.

The objective of a gearbox is to increase or reduce speed. Because of this, torque output would be the inverse of the function. If the enclosed drive is definitely a rate reducer, the torque output increase; if the drive increases speed, the torque output will decrease. Gear drive selection elements include: shaft orientation, velocity ratio, design type, nature of load, gear ranking, environment, mounting position, operating temperature range, and lubrication.

Basic Types of Gearboxes

Worm Gear Speed Reducers
A single reduction rate reducer can achieve up to a 100:1 decrease ratio in a small package. Referred to as right position drives, these contain a cylindrical worm with screw threads and a worm. With a single begin worm, the worm equipment advances only one tooth for each 360-degree convert of the worm. So, whatever the worm’s size, the apparatus ratio is the ‘size of the worm gear to 1′. Higher decrease ratios could be created by using double and triple decrease ratios.

Helical Gear Speed Reducers
Provide high-efficiency speed reduction 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. The two most common types will be the concentric (insight and output shafts are in series) and parallel shaft (insight and output shafts are offset). Single-stage helical gear reducers are typically used for equipment ratios up to about 8:1. Where reduced speeds and higher ratios are required, double, triple, and quadruple gear reduction stages may be used.

Cycloidal Disc Speed Reducers
Different from conventional gearing because they operate with out a high velocity pinion or equipment teeth, and the elements operate in compression rather than shear. This is due to the design of the cycloidal discs that roll within a band gear housing, comparable to a planetary style. The primary components will be 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, which 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 a specific gearset with a electric 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 your gear housing and input and result shafts to retain essential oil and prevent dirt. The most commonly utilized type, the radial lip seal, contains a steel casing that fits into the casing bore and an elastomeric sealing lip that presses on the shaft. Labyrinth seals are make use of for high-acceleration applications, and consist of a housing with some rings that limit leakage. A breather is definitely a connect with a hole that is 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, severe 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 strategies are a splash system and a circulating system
Worm Reduction Gearbox Software:

Worm drives are a compact method of substantially decreasing acceleration 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 considered.

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.
