Inline reducers (parallel shaft and planetary) are a perfect match for motors with high input speeds, or when gearmotor effectiveness is important. Get in touch with our technical sales staff for help determining which gearbox remedy is most beneficial for you.
RIGHT ANGLE REDUCERS
WORM GEAR REDUCER
EP’s worm gear reducers were created 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 correct angle gearboxes are designed with five mounting choices providing versatility when incorporating the reducer into product.
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 offer a robust solution. The proper angle bevel gearbox will come in 18 ratios ranging from 5:1 to 1000:1, in fact it is back-drivable at all ratios.
I-SERIES PLANETARY GEARBOX
Our I-Series little planetary gearbox configurations provide the smallest footprint and quietest procedure of our rate reducers. These gearboxes are made to handle varying loads with small backlash. With framework sizes 52cm, 62cm, and 81cm, 12 ratios which range from 5:1 to 308:1, we have a solution to suit your needs. Our 52 frame size can be available with plastic-type material gears for noise-delicate applications.
INLINE PLANETARY GEARBOX
Our inline planetary gearbox configurations provide the highest effectiveness and best output torque of all our acceleration reducers. These gearboxes are created to handle varying loads with little backlash. Planetary equipment reducers operate more quietly than parallel shaft reducers. With 18 ratio options ranging from 5:1 to 1000:1, we have a solution to fit your needs.
PARALLEL SHAFT GEARBOX
Parallel shaft gearboxes are the top choice for constant duty applications. Their gear cluster design provides a highly effective method for dissipating temperature. Parallel shaft gearboxes have the shortest length of our inline equipment reducer options so they work well in conditions with limited space. Our parallel shaft equipment reducers provide an affordable drop-in alternative solution for most little parallel shaft gearmotors.
Wormwheel gearboxes pass several names, including 90-degree gearboxes, right position gearboxes, swiftness reducers, worm equipment reducers and worm drive gearboxes. Gear reduction boxes include a gear arrangement in which a equipment in the form of a screw, also referred to as a worm, meshes with a worm gear. These gears are typically made from bronze and the worms are metal or stainless steel.
While worm gears are similar to a spur equipment, the worm gearboxes are considerably smaller than other equipment reduction boxes. A principal benefit of worm equipment reducers is certainly that they produce an output that’s 90° from the insight and can be utilized to transmit higher torque or decrease rotational speed. Most often, a worm gearbox has right hand threads; to improve the path of the result, a left-hands 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 middle distances from 7” to 20” (larger sizes on request). Output torque ranges from 33,000 in pounds. for the 7” CD EP-70 to 582,900 in pounds 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 installed.
These reducers are perfect for water/waste-water tools drive applications such as thickeners and clarifiers, which require a vertical straight down shaft. Other offered configurations also make Ever-Power triple reduction reducers perfect for make use of on mixers, elevators, solar panels, astronomical telescopes, indexing tables, hoists, conveyors, or various other process or materials handling systems where huge 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 swiftness reducers, are open gears contained in a housing. The casing supports bearings and shafts, holds in lubricants, and protects the components from surrounding conditions. Gearboxes can be found in a wide variety of load capacities and speed 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 velocity reducer, the torque result increase; if the drive raises speed, the torque output will decrease. Gear drive selection elements include: shaft orientation, swiftness 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 a 100:1 decrease ratio in a small package. Referred to as right angle drives, these contain a cylindrical worm with screw threads and a worm. With an individual begin worm, the worm equipment advances only one tooth for each 360-degree change of the worm. So, regardless of the worm’s size, the apparatus ratio may be the ‘size of the worm gear to 1′. Higher decrease 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 pieces of gears. Power can be transmitted from a high-rate pinion to a slower-speed equipment. Helical gears usually operate with their shafts parallel to one another. Both most common types are the concentric (insight and result shafts are in range) 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 lower speeds and higher ratios are needed, dual, triple, and quadruple gear reduction stages can be used.
Cycloidal Disc Speed Reducers
Different from conventional gearing because they operate with out a high swiftness pinion or equipment teeth, and the parts operate in compression rather than shear. This is because of the style of the cycloidal discs that roll within a band gear housing, similar to a planetary style. The primary components are 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 over 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 another NEMA C-face motor.
Seals and Breathers
Seals are used between the gear housing and insight and result shafts to retain oil and block dirt. The most commonly used type, the radial lip seal, includes a steel casing that fits in to the housing bore and an elastomeric sealing lip that presses on the shaft. Labyrinth seals are make use of for high-speed applications, and consist of a housing with some rings that limit leakage. A breather is usually a connect with a hole that’s mounted in the gear housing allowing airflow and relieve inner pressure.
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 styles include grease and solid film. Grease can be utilized for worm, planetary, cycloidal, and hypoidal reducers. Common distribution strategies are a splash system and a circulating system
Worm Reduction Gearbox App:
Worm drives are a compact means of substantially decreasing rate and increasing torque. Small electric motors are usually high-speed and low-torque; the addition of a worm drive increases the selection of applications that it might 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 industry devices, and on rudders. In addition, milling heads and rotary tables sit using high-precision duplex worm drives with adjustable backlash.
