Right angle worm reduction gearbox 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 efficiency is important. Contact our technical sales personnel for help identifying which gearbox answer is best for you.
RIGHT ANGLE REDUCERS
WORM GEAR REDUCER
EP’s worm equipment reducers are designed with a hollow bore and allow for a corner change with optional dual result. The reducers come in 12 ratios which range 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 top features of our correct angle worm and planetary inline reducers. With a good and efficient correct 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, 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 created to manage varying loads with little backlash. With framework sizes 52cm, 62cm, and 81cm, 12 ratios which range from 5:1 to 308:1, we’ve a solution to fit 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 provide the highest efficiency and best result torque of most our speed reducers. These gearboxes are designed to handle varying loads with small backlash. Planetary gear reducers operate more quietly than parallel shaft reducers. With 18 ratio choices ranging from 5:1 to 1000:1, we’ve a solution to suit your needs.
PARALLEL SHAFT GEARBOX
Parallel shaft gearboxes are the top choice for continuous duty applications. Their equipment cluster design provides a highly effective method for dissipating high temperature. Parallel shaft gearboxes possess the shortest amount of our inline equipment 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 little parallel shaft gearmotors.
Wormwheel gearboxes pass several names, including 90-degree gearboxes, right position gearboxes, speed reducers, worm equipment reducers and worm drive gearboxes. Gear reduction boxes include a gear arrangement when a equipment in the form of a screw, also referred to as a worm, meshes with a worm equipment. These gears are usually made 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 main benefit of worm equipment reducers can be that they create an output that’s 90° from the input and can be utilized to transmit higher torque or reduce rotational speed. Frequently, a worm gearbox provides right hand threads; to improve the direction of the result, a left-hand thread worm gearbox is necessary.

Ever-Power EP series triple-reduction worm gear quickness 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 pounds. 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 installed.
These reducers are well suited for water/waste-water apparatus drive applications such as thickeners and clarifiers, which require a vertical straight down shaft. Other obtainable 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 various other process or components handling systems where large torques/gradual speeds are needed.
These reducers are also available with a helical main reduction stage and are termed the HDVM series
Enclosed Gears / Gearboxes
Enclosed gears, also referred to as gearboxes or speed reducers, are open gears within a housing. The casing supports bearings and shafts, keeps in lubricants, and protects the parts from surrounding conditions. Gearboxes can be found in an array of load capacities and swiftness ratios.
The objective of a gearbox is to increase or reduce speed. Because of this, torque output will be the inverse of the function. If the enclosed drive is certainly a rate reducer, the torque output increase; if the drive increases speed, the torque result will decrease. Gear drive selection factors include: shaft orientation, acceleration 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 reduction 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 1 tooth for every 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 reduction ratios can be created through the use of double and triple reduction ratios.
Helical Gear Speed Reducers
Provide high-efficiency speed reduction through 1, 2, 3, or 4 units of gears. Power is usually transmitted from a high-rate 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 output shafts are in range) and parallel shaft (input and output shafts are offset). Single-stage helical equipment reducers are usually used for gear ratios up to about 8:1. Where reduced speeds and higher ratios are necessary, dual, triple, and quadruple gear reduction stages may be used.
Cycloidal Disc Speed Reducers
Not the same as conventional gearing because they operate without a high swiftness pinion or gear teeth, and the elements operate in compression rather than shear. This is because of the design of the cycloidal discs that roll within a ring gear housing, similar to a planetary style. The main components will be 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, that have feet for bolting, will be the most common.
Shaft-mounted reducers have 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’s driven by a separate NEMA C-face motor.
Seals and Breathers
Seals are used between the gear housing and insight and result shafts to retain oil and prevent dirt. The mostly used type, the radial lip seal, contains a metallic 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 consist of a housing with a series of bands that limit leakage. A breather is certainly a plug with a hole that is mounted in the apparatus housing to permit airflow and relieve internal pressure.
Enclosed gears are generally lubricated with oil. The most typical types of oil are rust and oxidation inhibiting, severe 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 Software:
Worm drives certainly are a compact method of substantially decreasing acceleration and increasing torque. Little 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 known as.
Worm drives are used in presses, in rolling mills, in conveying engineering, in mining sector machines, and on rudders. Furthermore, milling heads and rotary tables sit using high-precision duplex worm drives with adjustable backlash.
