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 performance is important. Contact our technical sales staff for help determining which gearbox remedy 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 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 correct angle gearboxes are designed with five mounting options providing flexibility when incorporating the reducer into product.
RIGHT ANGLE BEVEL GEARBOX
The right angle bevel gearbox combines the top 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 right angle bevel gearbox comes 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 small planetary gearbox configurations provide the smallest footprint and quietest procedure of our acceleration reducers. These gearboxes are designed to handle varying loads with little backlash. With frame sizes 52cm, 62cm, and 81cm, 12 ratios ranging from 5:1 to 308:1, we have a solution to suit your needs. Our 52 frame size is also available with plastic gears for noise-delicate applications.
INLINE PLANETARY GEARBOX
Our inline planetary gearbox configurations supply the highest effectiveness and best result torque of most our rate reducers. These gearboxes are created 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 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 high temperature. Parallel shaft gearboxes possess the shortest amount of our inline gear reducer options so they work very well in conditions with limited space. Our parallel shaft equipment reducers provide an affordable drop-in substitute solution for most little parallel shaft gearmotors.
Wormwheel gearboxes pass several names, including 90-degree gearboxes, right angle gearboxes, acceleration reducers, worm equipment reducers and worm drive gearboxes. Gear reduction boxes include a gear arrangement when a gear in the type of a screw, also called a worm, meshes with a worm gear. These gears are typically made from bronze and the worms are steel or stainless steel.
While worm gears act like a spur gear, the worm gearboxes are significantly smaller than other gear reduction boxes. A main benefit of worm gear reducers is usually that they generate an output that is 90° from the insight and can be utilized to transmit higher torque or decrease rotational speed. Most often, a worm gearbox provides right hand threads; to improve the direction of the result, a left-hands thread worm gearbox is required.

Ever-Power EP series triple-reduction worm gear rate 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 mounted.
These reducers are perfect for water/waste-water gear drive applications such as for example thickeners and clarifiers, which require a vertical straight down shaft. Other offered 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 huge torques/slower speeds are needed.
These reducers are also offered with a helical major reduction stage and are termed the HDVM series
Enclosed Gears / Gearboxes
Enclosed gears, also called gearboxes or speed reducers, are open gears contained in a housing. The housing facilitates bearings and shafts, retains in lubricants, and protects the elements from surrounding circumstances. Gearboxes are available in a wide variety of load capacities and velocity ratios.
The objective of a gearbox is to improve or reduce speed. Consequently, torque output will be the inverse of the function. If the enclosed drive is definitely a swiftness reducer, the torque result will increase; if the drive boosts speed, the torque result will reduce. Gear drive selection factors include: shaft orientation, swiftness 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 rate reducer can achieve up to 100:1 reduction ratio in a little package. Known as right position 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 gear ratio is the ‘size of the worm equipment to 1′. Higher decrease ratios can be created by using double and triple reduction ratios.
Helical Gear Speed Reducers
Provide high-efficiency speed decrease through 1, 2, 3, or 4 models of gears. Power is transmitted from a high-velocity pinion to a slower-speed equipment. Helical gears usually operate with their shafts parallel to each other. The two most common types are the concentric (insight and output shafts are in line) and parallel shaft (input and output shafts are offset). Single-stage helical equipment reducers are usually used for equipment ratios up to about 8:1. Where reduced speeds and higher ratios are necessary, dual, triple, and quadruple equipment reduction stages can be used.
Cycloidal Disc Speed Reducers
Different from conventional gearing because they operate with out a high rate 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 ring gear housing, comparable to a planetary style. The main 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, are the most common.
Shaft-mounted reducers have a hollow output shaft that slips more than the driven shaft.
A gearmotor combines an enclosed gearset with a engine. A motorized reducer resembles a gearmotor except that it is driven by another NEMA C-face motor.
Seals and Breathers
Seals are used between your gear housing and input and result shafts to retain oil and prevent dirt. The most commonly utilized type, the radial lip seal, includes a metal casing that fits into the housing bore and an elastomeric sealing lip that presses on the shaft. Labyrinth seals are use for high-acceleration applications, and contain a housing with a series of rings that limit leakage. A breather is usually a connect with a hole that is mounted in the apparatus housing to permit airflow and relieve inner pressure.
Enclosed gears are worm reduction gearbox generally lubricated with oil. The most common types of essential oil are rust and oxidation inhibiting, severe pressure, compounded, and synthetic. Other styles include grease and solid film. Grease can be used for worm, planetary, cycloidal, and hypoidal reducers. Common distribution methods are a splash system and a circulating system
Worm Reduction Gearbox Application:
Worm drives certainly 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 range of applications that it may be suitable for, especially when the worm drive’s compactness is known as.
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.
