Correct angle gearboxes (worm and planetary) are tough and built for 90° turns. Inline reducers (parallel shaft and planetary) are a perfect match for motors with high insight 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 equipment reducers were created with a hollow bore and invite for a corner turn with optional dual result. The reducers come in 12 ratios ranging from 5:1 to 100:1, with non-back-drivable ratios 30:1 and higher. Our correct angle gearboxes were created with five mounting options providing versatility when incorporating the reducer into item.
RIGHT ANGLE BEVEL GEARBOX
The right angle bevel gearbox combines the features of our correct angle worm and planetary inline reducers. With a good and efficient correct angle configuration, our right angle planetary gearboxes provide a robust solution. The right angle bevel gearbox comes in 18 ratios which range 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 supply the smallest footprint and quietest procedure of our speed reducers. These gearboxes are created to deal with 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 is also available with plastic gears for noise-sensitive applications.
INLINE PLANETARY GEARBOX
Our inline planetary gearbox configurations provide the highest performance and best output torque of all our velocity reducers. These gearboxes are made to deal with varying loads with small backlash. Planetary gear reducers operate more quietly than parallel shaft reducers. With 18 ratio options which range from 5:1 to 1000:1, we have a solution to fit your needs.
PARALLEL SHAFT GEARBOX
Parallel shaft gearboxes will be the top choice for constant duty applications. Their gear cluster design provides an effective method for dissipating heat. Parallel shaft gearboxes have the shortest amount of our inline equipment reducer options therefore they work very well in conditions with limited space. Our parallel shaft equipment reducers provide an affordable drop-in replacement solution for most small parallel shaft gearmotors.
Wormwheel gearboxes go by several names, including 90-degree gearboxes, right position gearboxes, swiftness reducers, worm equipment reducers and worm drive gearboxes. Gear reduction boxes feature a gear arrangement in which a gear in the form of a screw, also known as a worm, meshes with a worm gear. 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 gear reduction boxes. A major benefit of worm gear reducers is definitely that they produce an output that’s 90° from the insight and can be used to transmit higher torque or decrease rotational speed. Most often, a worm gearbox has right hand threads; to change the direction of the result, a left-hand thread worm gearbox is required.

Ever-Power EP series triple-reduction worm gear velocity 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 lbs. 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 mounted.
These reducers are perfect for water/waste-water gear drive applications such as thickeners and clarifiers, which require a vertical straight down shaft. Other available configurations also make Ever-Power triple decrease reducers perfect for make use of on mixers, elevators, solar panels, astronomical telescopes, indexing tables, hoists, conveyors, or other process or components handling systems where large 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 known as gearboxes or speed 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 are available in an array of load capacities and velocity ratios.
The objective 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 rate reducer, the torque result increase; if the drive improves speed, the torque result will reduce. Gear drive selection factors include: shaft orientation, rate 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 quickness reducer can achieve up to a 100:1 reduction ratio in a little package. Referred to as right position drives, these contain a cylindrical worm with screw threads and a worm. With a single start worm, the worm gear advances only 1 tooth for each 360-degree switch of the worm. So, whatever the worm’s size, the apparatus ratio is the ‘size of the worm gear to 1′. Higher reduction ratios could be created by using double and triple reduction ratios.
Helical Gear Speed Reducers
Provide high-efficiency speed reduction through 1, 2, 3, or 4 models of gears. Power is definitely transmitted from a high-rate pinion to a slower-speed equipment. Helical gears usually operate with their shafts parallel to each other. Both most common types will be the concentric (input and result shafts are in range) and parallel shaft (input and result shafts are offset). Single-stage helical equipment reducers are usually used for equipment ratios up to about 8:1. Where reduce speeds and higher ratios are required, dual, triple, and quadruple gear 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 parts operate in compression instead of 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 will be the eccentric cam, the internally flanged output shaft, the discs, and the ring gear housing.
Three Mounting Options
(L-R) Base 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 over the driven shaft.
A gearmotor combines an enclosed gearset with a 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 your gear housing and input and result shafts to retain oil and block dirt. The most commonly used type, the radial lip seal, contains a steel casing that fits in to the casing bore and an elastomeric sealing lip that presses on the shaft. Labyrinth seals are make use of for high-acceleration applications, and contain a housing with some rings that limit leakage. A breather is definitely a plug with a hole that’s mounted in the apparatus housing allowing airflow and relieve inner pressure.
Enclosed gears are generally lubricated with oil. The most typical types of oil are rust and oxidation inhibiting, extreme pressure, compounded, and synthetic. Other styles consist of grease and solid film. Grease can be used for worm, planetary, cycloidal, and hypoidal reducers. Common distribution strategies are a splash program and a circulating system
Worm Reduction Gearbox Application:
Worm drives are a compact method of substantially decreasing quickness 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 might be suitable for, specially when the worm drive’s compactness is known as.
Worm drives are found in presses, in rolling mills, in conveying engineering, in mining market devices, and on rudders. In addition, milling heads and rotary tables sit using high-precision duplex worm drives with adjustable backlash.
