GEARBOX REDUCERS
Right angle gearboxes (worm and planetary) are durable and built for 90° turns. Inline reducers (parallel shaft and planetary) are an ideal match for motors with high insight speeds, or when gearmotor effectiveness is important. Contact our technical sales staff for help identifying which gearbox remedy is best 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 can be found in 12 ratios ranging from 5:1 to 100:1, with non-back-drivable ratios 30:1 and higher. Our correct angle gearboxes are designed with five mounting options providing versatility when incorporating the reducer into product.
RIGHT ANGLE BEVEL GEARBOX

Our inline planetary gearbox configurations provide the highest efficiency and best result torque of all our acceleration reducers. These gearboxes are made to manage varying loads with small backlash. Planetary gear reducers operate more quietly than parallel shaft reducers. With 18 ratio options ranging from 5:1 to 1000:1, we’ve a solution to fit your needs.
PARALLEL SHAFT GEARBOX
parallel-shaft-gearbox
Parallel shaft gearboxes are the best choice for constant duty applications. Their equipment cluster design provides an effective method for dissipating high temperature. Parallel shaft gearboxes have the shortest length 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 substitute solution for most small parallel shaft gearmotors.
Wormwheel gearboxes go by several names, including 90-degree gearboxes, right position gearboxes, rate 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 steel or stainless steel.

While worm gears act like a spur equipment, the worm gearboxes are considerably smaller than other equipment reduction boxes. A main benefit of worm equipment reducers is that they produce an output that’s 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 change the path of the output, a left-hand 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 center distances from 7” to 20” (larger sizes on request). Output 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 are available in four configurations: horizontal, vertical, shafted, and shaft installed.

These reducers are well suited for water/waste-water equipment drive applications such as thickeners and clarifiers, which need 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 additional process or components handling systems where large torques/gradual speeds are needed.

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

Enclosed Gears / Gearboxes
Enclosed gears, also referred to as gearboxes or quickness reducers, are open gears within a housing. The housing facilitates bearings and shafts, holds in lubricants, and protects the elements from surrounding conditions. Gearboxes are available in an array of load capacities and rate ratios.

The objective of a gearbox is to increase or reduce speed. As a result, torque output will be the inverse of the function. If the enclosed drive is definitely a quickness reducer, the torque result will increase; if the drive raises speed, the torque output will decrease. Gear drive selection elements include: shaft orientation, acceleration ratio, design type, nature of load, gear rating, environment, mounting position, working temperature range, and lubrication.

Basic Types of Gearboxes

Worm Gear Speed Reducers
A single reduction quickness reducer can achieve up to 100:1 reduction ratio in a little 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 gear advances only 1 tooth for every 360-degree convert of the worm. So, regardless of the worm’s size, the apparatus ratio is the ‘size of the worm gear to 1′. Higher reduction ratios could be created by using double and triple reduction ratios.

Helical Gear Speed Reducers
Provide high-efficiency speed decrease through 1, 2, 3, or 4 sets of gears. Power is usually transmitted from a high-speed pinion to a slower-speed gear. Helical gears generally operate with their shafts parallel to one another. The two most common types are the concentric (insight and output shafts are in range) and parallel shaft (input and result shafts are offset). Single-stage helical gear reducers are typically used for gear ratios up to about 8:1. Where lower speeds and higher ratios are necessary, 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 acceleration pinion or equipment teeth, and the elements operate in compression rather than shear. This is due to the style of the cycloidal discs that roll within a band gear housing, comparable 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, that have feet for bolting, will be the most common.

Shaft-mounted reducers possess 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 output shafts to retain essential oil and block dirt. The mostly used type, the radial lip seal, consists of a metallic casing that fits into the casing bore and an elastomeric sealing lip that presses on the shaft. Labyrinth seals are use for high-swiftness applications, and contain a housing with a series of rings that limit leakage. A breather is definitely a plug with a hole that is mounted in the gear housing allowing airflow and relieve internal pressure.

Lubrication
Enclosed gears are generally lubricated with oil. The most common types of essential oil are rust and oxidation inhibiting, intense pressure, compounded, and synthetic. Other styles include 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 Application:

Worm drives are a compact method of substantially decreasing rate 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 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 machines, and on rudders. In addition, milling heads and rotary tables are positioned using high-precision duplex worm drives with adjustable backlash.
