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 insight speeds, or when gearmotor performance is important. Contact our technical sales personnel for help identifying which gearbox solution is most beneficial 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 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 options providing flexibility when incorporating the reducer into product.
RIGHT ANGLE BEVEL GEARBOX
The proper angle bevel gearbox combines the features of our correct angle worm and planetary inline reducers. With a good and efficient right angle configuration, our correct angle planetary gearboxes provide a robust solution. The right 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 small planetary gearbox configurations supply the smallest footprint and quietest procedure of our acceleration reducers. These gearboxes are designed to manage 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 fit your needs. Our 52 frame size is also available with plastic material gears for noise-delicate applications.
INLINE PLANETARY GEARBOX
Our inline planetary gearbox configurations supply the highest efficiency and best output torque of most our speed reducers. These gearboxes are designed to manage varying loads with little 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 suit your needs.
PARALLEL SHAFT GEARBOX
Parallel shaft gearboxes will be the top choice for continuous duty applications. Their equipment cluster design provides an effective method for dissipating warmth. 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 offer an affordable drop-in substitute solution for most small parallel shaft gearmotors.
Wormwheel gearboxes pass several names, including 90-degree gearboxes, right angle gearboxes, quickness reducers, worm gear reducers and worm drive gearboxes. Gear decrease boxes feature a gear arrangement in which a gear in the kind of a screw, also called a worm, meshes with a worm equipment. These gears are usually created from bronze and the worms are metal or stainless steel.
While worm gears act like a spur equipment, the worm gearboxes are significantly smaller than other equipment reduction boxes. A major benefit of worm equipment reducers is certainly that they create an output that is 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 path of the result, a left-hand thread worm gearbox is required.

Ever-Power EP series triple-reduction worm gear swiftness reducers can be found in ratios from 5000:1 to 175,000:1 and center 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 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 well suited for water/waste-water gear drive applications such as for example 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 power panels, astronomical telescopes, indexing tables, hoists, conveyors, or additional process or materials handling systems where huge torques/slower speeds are needed.
These reducers are also available with a helical worm reduction gearbox principal 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, holds in lubricants, and protects the components from surrounding conditions. Gearboxes can be found in an array of load capacities and quickness ratios.
The purpose of a gearbox is to improve or reduce speed. Because of this, torque output will be the inverse of the function. If the enclosed drive is definitely a velocity reducer, the torque result increase; if the drive improves speed, the torque result will reduce. Gear drive selection elements include: shaft orientation, rate ratio, design type, character 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 decrease ratio in a little package. Referred to as right angle drives, these contain a cylindrical worm with screw threads and a worm. With a single start worm, the worm equipment advances only 1 tooth for every 360-degree convert of the worm. So, whatever the worm’s size, the gear ratio is the ‘size of the worm equipment to 1′. Higher decrease ratios could be created by using double and triple decrease ratios.
Helical Gear Speed Reducers
Provide high-efficiency speed reduction through 1, 2, 3, or 4 models of gears. Power is certainly transmitted from a high-rate pinion to a slower-speed equipment. Helical gears generally operate with their shafts parallel to one another. The two most common types will be the concentric (insight and result shafts are in line) and parallel shaft (input and output shafts are offset). Single-stage helical equipment reducers are typically used for gear ratios up to about 8:1. Where reduce speeds and higher ratios are needed, 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 swiftness pinion or equipment teeth, and the components operate in compression instead of shear. This is because of the design of the cycloidal discs that roll within a band 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 housing.
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, will be the most common.
Shaft-mounted reducers possess 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 essential oil and prevent dirt. The most commonly utilized type, the radial lip seal, consists of a metallic casing that fits in to 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 bands that limit leakage. A breather can be a plug with a hole that’s mounted in the apparatus housing to permit airflow and relieve inner pressure.
Enclosed gears are generally lubricated with oil. The most typical types of essential oil are rust and oxidation inhibiting, intense 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 App:
Worm drives are a compact method of substantially decreasing acceleration 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 could be suitable for, particularly when the worm drive’s compactness is known as.
Worm drives are used in presses, in rolling mills, in conveying engineering, in mining sector devices, and on rudders. Furthermore, milling heads and rotary tables are positioned using high-precision duplex worm drives with adjustable backlash.
