GEARBOX REDUCERS
Right 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 efficiency is important. Contact our technical sales staff for help determining which gearbox option is best for you.
RIGHT ANGLE REDUCERS
WORM GEAR REDUCER
EP’s worm gear reducers are designed with a hollow bore and invite for a corner switch 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 correct 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 best choice for continuous duty applications. Their gear cluster design provides a highly effective method for dissipating high temperature. Parallel shaft gearboxes have the shortest amount of our inline gear reducer options therefore they work well in conditions with limited space. Our parallel shaft gear reducers offer an affordable drop-in substitute solution for most little parallel shaft gearmotors.
Wormwheel gearboxes pass several names, including 90-degree gearboxes, right position gearboxes, speed reducers, worm equipment reducers and worm drive gearboxes. Gear decrease 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 metal or stainless steel.

While worm gears act like a spur gear, the worm gearboxes are significantly smaller than other equipment reduction boxes. A principal benefit of worm gear reducers is definitely that they produce an output that’s 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 necessary.

Ever-Power EP series triple-reduction worm gear acceleration reducers are available in ratios from 5000:1 to 175,000:1 and center distances from 7” to 20” (larger sizes available on request). Output torque ranges from 33,000 in lbs. for the 7” CD EP-70 to 582,900 in lbs 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 require a vertical straight down shaft. Other obtainable configurations also make Ever-Power triple reduction reducers perfect for use on mixers, elevators, solar panels, astronomical telescopes, indexing tables, hoists, conveyors, or other process or components handling systems where huge torques/gradual speeds are needed.

These reducers are also available with a helical main 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 housing supports bearings and shafts, holds in lubricants, and protects the parts from surrounding circumstances. Gearboxes can be found in an array of load capacities and speed 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 can be a quickness reducer, the torque output increase; if the drive boosts speed, the torque result will decrease. Gear drive selection factors 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 velocity reducer can achieve up to a 100:1 decrease ratio in a small package. Known as right position drives, these consist of a cylindrical worm with screw threads and a worm. With a single start worm, the worm gear advances only 1 tooth for each 360-degree turn of the worm. So, whatever the worm’s size, the apparatus ratio is the ‘size of the worm equipment to 1′. Higher reduction 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 sets of gears. Power is certainly transmitted from a high-velocity pinion to a slower-speed gear. Helical gears generally operate with their shafts parallel to each other. Both most common types will be the concentric (insight and result shafts are in series) and parallel shaft (input and result 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, dual, triple, and quadruple gear reduction stages may 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 parts operate in compression rather than shear. This is due to 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, which have feet for bolting, are the most common.

Shaft-mounted reducers possess a hollow output shaft that slips over the driven shaft.

A gearmotor combines a specific gearset with a engine. 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 input and output shafts to retain essential oil and prevent dirt. The most commonly used type, the radial lip seal, consists of 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-rate applications, and consist of a housing with a series of rings that limit leakage. A breather is a connect with a hole that is mounted in the gear housing to permit airflow and relieve inner pressure.

Lubrication
Enclosed gears are usually lubricated with oil. The most common types of oil are rust and oxidation inhibiting, worm reduction gearbox severe pressure, compounded, and synthetic. Other styles 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 method of substantially decreasing rate and increasing torque. Small electric motors are usually high-speed and low-torque; the addition of a worm drive escalates the range of applications that it could be suitable for, specially when the worm drive’s compactness is considered.

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 sit using high-precision duplex worm drives with adjustable backlash.
