RIGHT ANGLE REDUCERS
WORM GEAR REDUCER
EP’s worm gear reducers were created with a hollow bore and allow for a corner switch 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 flexibility when incorporating the reducer into product.
RIGHT ANGLE BEVEL GEARBOX
worm reduction gearbox bevel-right-angle-gearbox
The right angle bevel gearbox combines the features of our correct angle worm and planetary inline reducers. With a solid and efficient right angle configuration, our right angle planetary gearboxes offer a robust solution. The proper angle bevel gearbox will come 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 little planetary gearbox configurations provide the smallest footprint and quietest operation of our acceleration reducers. These gearboxes are made to handle varying loads with small backlash. With body 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-sensitive applications.
INLINE PLANETARY GEARBOX
Our inline planetary gearbox configurations supply the highest performance and best output torque of most our quickness reducers. These gearboxes are created to handle 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 gearboxes are the best choice for continuous duty applications. Their gear cluster design provides an effective method for dissipating heat. Parallel shaft gearboxes possess the shortest amount of our inline gear reducer options so they work very well in environments with limited space. Our parallel shaft equipment reducers provide an affordable drop-in substitute solution for most small parallel shaft gearmotors.
Wormwheel gearboxes go by several names, including 90-degree gearboxes, right angle gearboxes, quickness reducers, worm equipment reducers and worm drive gearboxes. Gear reduction boxes feature a gear arrangement when a gear in the type of a screw, also called a worm, meshes with a worm equipment. These gears are usually made from bronze and the worms are steel or stainless steel.
While worm gears are similar to a spur equipment, the worm gearboxes are considerably smaller than other gear reduction boxes. A principal benefit of worm gear reducers can be that they produce 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 has right hand threads; to change the direction of the output, a left-hand thread worm gearbox is necessary.

Ever-Power EP series triple-reduction worm gear acceleration reducers are available in ratios from 5000:1 to 175,000:1 and center distances from 7” to 20” (larger sizes available on request). Result torque ranges from 33,000 in lbs. 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 are available in four configurations: horizontal, vertical, shafted, and shaft installed.
These reducers are ideal for water/waste-water apparatus drive applications such as thickeners and clarifiers, which need a vertical down shaft. Other available 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 offered with a helical primary reduction stage and are termed the HDVM series
Enclosed Gears / Gearboxes
Enclosed gears, also called gearboxes or swiftness reducers, are open gears within a housing. The housing supports bearings and shafts, holds in lubricants, and protects the elements from surrounding circumstances. Gearboxes are available in a wide selection of load capacities and speed ratios.
The objective of a gearbox is to improve or reduce speed. Consequently, torque output would be the inverse of the function. If the enclosed drive is definitely a acceleration reducer, the torque result will increase; if the drive increases speed, the torque output will reduce. Gear drive selection factors include: shaft orientation, velocity ratio, design type, nature of load, gear ranking, 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 small package. Referred to as right angle drives, these consist of a cylindrical worm with screw threads and a worm. With an individual start worm, the worm equipment advances only 1 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 can be created through the use of double and triple reduction ratios.
Helical Gear Speed Reducers
Provide high-efficiency speed decrease through 1, 2, 3, or 4 units of gears. Power is usually transmitted from a high-quickness 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 necessary, double, triple, and quadruple equipment reduction stages can be used.
Cycloidal Disc Speed Reducers
Not the same as conventional gearing because they operate without a high acceleration pinion or gear teeth, and the components 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 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) Base 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 possess a hollow output shaft that slips more than 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 another NEMA C-face motor.
Seals and Breathers
Seals are used between the gear housing and input and result shafts to retain essential oil and block dirt. The mostly utilized type, the radial lip seal, consists of a metal casing that fits in to the casing bore and an elastomeric sealing lip that presses on the shaft. Labyrinth seals are use for high-rate applications, and contain a housing with a series of rings that limit leakage. A breather is certainly a plug with a hole that’s mounted in the gear housing allowing airflow and relieve internal pressure.
Enclosed gears are usually 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 methods are a splash system and a circulating system
Worm Reduction Gearbox Application:
Worm drives are a compact method of substantially decreasing speed and increasing torque. Small electric motors are generally high-speed and low-torque; the addition of a worm drive increases the selection of applications that it could be suitable for, especially when the worm drive’s compactness is considered.
Worm drives are found in presses, in rolling mills, in conveying engineering, in mining industry machines, and on rudders. Furthermore, milling heads and rotary tables are positioned using high-precision duplex worm drives with adjustable backlash.
