Right angle gearboxes (worm and planetary) are tough and built for 90° turns. Inline reducers (parallel shaft and planetary) are an ideal 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 answer is most beneficial for you.
RIGHT ANGLE REDUCERS
WORM GEAR REDUCER
EP’s worm gear reducers are designed with a hollow bore and allow for a corner change with optional dual output. 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 are designed with five mounting options providing flexibility when incorporating the reducer into item.
RIGHT ANGLE BEVEL GEARBOX
The proper angle bevel gearbox combines the features of our right angle worm and planetary inline reducers. With a solid and efficient right angle configuration, our correct angle planetary gearboxes provide a robust solution. The proper angle bevel gearbox comes in 18 ratios ranging from 5:1 to 1000:1, and it is back-drivable at all ratios.
I-SERIES PLANETARY GEARBOX
Our I-Series small planetary gearbox configurations provide the smallest footprint and quietest procedure of our quickness reducers. These gearboxes are designed to manage varying loads with small backlash. With body sizes 52cm, 62cm, and 81cm, 12 ratios ranging from 5:1 to 308:1, we have a solution to fit your needs. Our 52 frame size can be available with plastic material gears for noise-delicate applications.
INLINE PLANETARY GEARBOX
Our inline planetary gearbox configurations supply the highest effectiveness and best output torque of most our velocity reducers. These gearboxes are designed to deal with varying loads with little 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 suit your needs.
PARALLEL SHAFT GEARBOX
Parallel shaft gearboxes are the best choice for constant duty applications. Their gear cluster design provides a highly effective method for dissipating warmth. Parallel shaft gearboxes possess the shortest length of our inline gear reducer options so they work well in conditions with limited space. Our parallel shaft gear reducers provide an affordable drop-in substitute solution for most small parallel shaft gearmotors.
Wormwheel gearboxes pass several names, including 90-degree gearboxes, right position gearboxes, acceleration reducers, worm equipment reducers and worm drive gearboxes. Gear reduction boxes feature a gear arrangement when a equipment in the kind of a screw, also known as a worm, meshes with a worm equipment. 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 significantly smaller than other equipment reduction boxes. A main benefit of worm gear reducers is usually that they produce an output that is 90° from the input and can be utilized to transmit higher torque or reduce rotational speed. Frequently, a worm gearbox has right hand threads; to improve the direction of the output, a left-hand thread worm gearbox is required.

Ever-Power EP series triple-reduction worm gear rate 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 pounds. 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 are available in four configurations: horizontal, vertical, shafted, and shaft installed.
These reducers are perfect for water/waste-water apparatus drive applications such as thickeners and clarifiers, which need a vertical straight 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 components handling systems where large torques/sluggish speeds are needed.
These reducers are also available with a helical principal reduction stage and are termed the HDVM series
Enclosed Gears / Gearboxes
Enclosed gears, also called gearboxes or swiftness reducers, are open gears contained in a housing. The housing facilitates bearings and shafts, keeps in lubricants, and protects the parts from surrounding circumstances. Gearboxes can be found in a wide selection of load capacities and rate ratios.
The purpose 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 usually a acceleration reducer, the torque result increase; if the drive boosts speed, the torque output will decrease. Gear drive selection factors include: shaft orientation, quickness ratio, design type, character of load, gear ranking, environment, mounting position, working temperature range, and lubrication.
Basic Types of Gearboxes
Worm Gear Speed Reducers
A single reduction acceleration reducer can achieve up to 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 begin worm, the worm gear advances only one tooth for each 360-degree change of the worm. So, whatever 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 decrease through 1, 2, 3, or 4 units of gears. Power can be 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 (input and result shafts are in line) and parallel shaft (insight and result shafts are offset). Single-stage helical gear reducers are typically used for equipment ratios up to about 8:1. Where lower speeds and higher ratios are required, double, 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 quickness pinion or gear teeth, and the parts operate in compression instead of shear. This is because of the design of the cycloidal discs that roll within a band 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 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 more than the driven shaft.
A gearmotor combines an enclosed 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 the gear housing and insight and output shafts to retain essential oil and prevent dirt. The most commonly used type, the radial lip seal, includes a metal 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 consist of a housing with some rings that limit leakage. A breather is certainly a plug with a hole that’s mounted in the gear housing to permit airflow and relieve internal pressure.
Enclosed gears are generally lubricated with oil. The most common types of essential oil are rust and oxidation inhibiting, severe pressure, compounded, and synthetic. Other types include grease and solid film. Grease can be used for worm, planetary, cycloidal, and hypoidal reducers. Common distribution methods are a splash program and a circulating system
Worm Reduction Gearbox App:
Worm drives are a compact means of substantially decreasing speed and increasing torque. Small electric motors are usually high-speed and low-torque; the addition of a worm drive escalates the selection of applications that it may be suitable for, especially when the worm drive’s compactness is considered.
Worm drives are used in presses, in rolling mills, in conveying engineering, in mining industry devices, and on rudders. Furthermore, milling heads and rotary tables are positioned using high-precision duplex worm drives with adjustable backlash.
