Correct angle gearboxes (worm and planetary) are rugged and built for 90° turns. Inline reducers (parallel shaft and planetary) are an ideal match for motors with high input speeds, or when gearmotor efficiency is important. Get in touch with our technical sales personnel 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 turn with optional dual output. The reducers come in 12 ratios ranging from 5:1 to 100:1, with non-back-drivable ratios 30:1 and higher. Our right angle gearboxes were created with five mounting choices providing flexibility when incorporating the reducer into item.
RIGHT ANGLE BEVEL GEARBOX
The proper angle bevel gearbox combines the features of our correct angle worm and planetary inline reducers. With a solid and efficient correct angle configuration, our right 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 supply the smallest footprint and quietest operation of our acceleration reducers. These gearboxes are made to manage varying loads with small backlash. With frame sizes 52cm, 62cm, and 81cm, 12 ratios ranging from 5:1 to 308:1, we’ve a solution to suit your needs. Our 52 frame size can be available with plastic gears for noise-sensitive applications.
INLINE PLANETARY GEARBOX
Our inline planetary gearbox configurations supply the highest performance and best output torque of all our quickness 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 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 an effective method for dissipating temperature. Parallel shaft gearboxes have the shortest length of our inline gear reducer options therefore they work well in conditions with limited space. Our parallel shaft equipment reducers provide an affordable drop-in replacement solution for most little parallel shaft gearmotors.
Wormwheel gearboxes go by several names, including 90-degree gearboxes, right angle gearboxes, acceleration reducers, worm equipment reducers and worm drive gearboxes. Gear reduction boxes feature a gear arrangement in which a gear in the kind of a screw, also referred to as a worm, meshes with a worm gear. These gears are usually created from bronze and the worms are metal or stainless steel.
While worm gears are similar to a spur gear, the worm gearboxes are considerably smaller than other gear reduction boxes. A main benefit of worm gear reducers is definitely that they create an output that’s 90° from the insight and can be utilized to transmit higher torque or decrease rotational speed. Frequently, a worm gearbox has right hand threads; to change the direction of the result, a left-hands thread worm gearbox is required.

Ever-Power EP series triple-reduction worm gear acceleration reducers are available in ratios from 5000:1 to 175,000:1 and middle distances from 7” to 20” (larger sizes on request). Result torque ranges from 33,000 in pounds. for the 7” CD EP-70 to 582,900 in lbs 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 tools drive applications such as for example thickeners and clarifiers, which need a vertical straight down shaft. Other offered configurations also make Ever-Power triple reduction reducers perfect for make use of on mixers, elevators, solar power panels, astronomical telescopes, indexing tables, hoists, conveyors, or additional process or materials handling systems where huge torques/slow 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 called gearboxes or rate reducers, are open gears contained in a housing. The casing facilitates bearings and shafts, retains in lubricants, and protects the parts from surrounding circumstances. Gearboxes can be found in an array of load capacities and swiftness 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 definitely a swiftness reducer, the torque output will increase; if the drive raises speed, the torque result will reduce. Gear drive selection factors include: shaft orientation, rate ratio, design type, character of load, gear rating, environment, mounting position, operating temperature range, and lubrication.
Basic Types of Gearboxes
Worm Gear Speed Reducers
A single reduction rate reducer can achieve up to a 100:1 decrease ratio in a little package. Referred to as right position drives, these consist of 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 switch 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 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 is usually transmitted from a high-swiftness pinion to a slower-speed equipment. Helical gears usually operate with their shafts parallel to each other. Both most common types are the concentric (insight and result 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 decrease speeds and higher ratios are necessary, double, triple, and quadruple equipment reduction stages may be used.
Cycloidal Disc Speed Reducers
Not the same as conventional gearing because they operate without a high velocity pinion or equipment teeth, and the components operate in compression instead of shear. This is due to the design of the cycloidal discs that roll within a ring gear housing, comparable to a planetary design. The primary components are the eccentric cam, the internally flanged output shaft, the discs, and the ring gear casing.
Three Mounting Options
(L-R) Bottom 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 have a hollow output shaft that slips over the driven shaft.
A gearmotor combines a specific gearset with a electric 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 input and output shafts to retain oil and prevent dirt. The mostly 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 use for high-velocity applications, and consist of a housing with some bands that limit leakage. A breather can be a plug with a hole that is mounted in the gear housing allowing airflow and relieve internal pressure.
Enclosed gears are generally lubricated with oil. The most common types of oil are rust and oxidation inhibiting, extreme pressure, compounded, and synthetic. Other types 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 are a compact method of substantially decreasing velocity and increasing torque. Little electric motors are generally 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 market machines, and on rudders. Furthermore, milling heads and rotary tables sit using high-precision duplex worm drives with adjustable backlash.
