GEARBOX REDUCERS
Correct angle 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 input speeds, or when gearmotor effectiveness is important. Contact our technical sales personnel for help determining which gearbox solution 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 output. 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 are designed with five mounting choices providing versatility when incorporating the reducer into product.
RIGHT ANGLE BEVEL GEARBOX

Our 52 frame size can be available with plastic-type gears for noise-sensitive applications.
INLINE PLANETARY GEARBOX
inline-planetary-gearbox
Our inline planetary gearbox configurations provide the highest performance and best result torque of most our quickness reducers. These gearboxes are designed to manage varying loads with small backlash. Planetary equipment reducers operate more quietly than parallel shaft reducers. With 18 ratio choices ranging from 5:1 to 1000:1, we have a solution to suit your needs.
PARALLEL SHAFT GEARBOX
parallel-shaft-gearbox
Parallel shaft gearboxes will be the best choice for constant duty applications. Their gear cluster design provides an effective method for dissipating high temperature. Parallel shaft gearboxes possess the shortest amount of our inline equipment reducer options therefore they work very well in environments with limited space. Our parallel shaft gear reducers offer 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 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 typically created from bronze and the worms are metal or stainless steel.
While worm gears act like a spur equipment, the worm gearboxes are considerably smaller than other equipment reduction boxes. A main benefit of worm gear reducers is certainly that they generate an output that is 90° from the insight and can be used to transmit higher torque or decrease rotational speed. Most often, a worm gearbox offers right hand threads; to change the path of the result, a left-hands 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 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 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 can be found 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 need a vertical straight down shaft. Other offered 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 materials handling systems where large torques/gradual speeds are needed.
These reducers are also offered with a helical primary reduction stage and so are termed the HDVM series
Enclosed Gears / Gearboxes
Enclosed gears, also referred to as gearboxes or quickness reducers, are open gears contained in a housing. The casing facilitates bearings and shafts, keeps in lubricants, and protects the parts from surrounding conditions. Gearboxes are available in a wide variety of load capacities and speed ratios.
The purpose of a gearbox is to increase or reduce speed. Consequently, torque output would be the inverse of the function. If the enclosed drive is a quickness reducer, the torque result increase; if the drive increases speed, the torque output will decrease. Gear drive selection factors include: shaft orientation, rate ratio, design type, nature of load, gear rating, 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 100:1 reduction ratio in a small package. Referred to as right angle drives, these contain a cylindrical worm with screw threads and a worm. With a single begin worm, the worm gear advances only one tooth for each 360-degree convert of the worm. So, whatever the worm’s size, the gear ratio is the ‘size of the worm gear to 1′. Higher reduction ratios can be created through the use of double and triple decrease ratios.
Helical Gear Speed Reducers
Provide high-efficiency speed decrease through 1, 2, 3, or 4 units of gears. Power is certainly transmitted from a high-swiftness pinion to a slower-speed gear. Helical gears usually operate with their shafts parallel to each other. Both most common types are the concentric (input and result shafts are in collection) and parallel shaft (input and output shafts are offset). Single-stage helical gear reducers are typically used for gear ratios up to about 8:1. Where reduce speeds and higher ratios are needed, double, 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 acceleration pinion or equipment teeth, and the components operate in compression instead of shear. This is due to the style of the cycloidal discs that roll within a band gear housing, similar to a planetary design. The main components are the eccentric cam, the internally flanged output shaft, the discs, and the ring gear housing.
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, will be 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 your gear housing and insight and output shafts to retain essential oil and prevent dirt. The mostly used type, the radial lip seal, includes a steel 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 consist of a housing with a series of bands that limit leakage. A breather is usually a plug with a hole that is mounted in the apparatus housing to permit airflow and relieve internal pressure.
Lubrication
Enclosed gears are generally lubricated with oil. The most common types of 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 strategies are a splash system and a circulating system
Worm Reduction Gearbox Software:
Worm drives certainly are a compact means of substantially decreasing rate and increasing torque. Little electric motors are usually high-speed and low-torque; the addition of a worm drive increases the range of applications that it may 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 sector machines, and on rudders. In addition, milling heads and rotary tables are positioned using high-precision duplex worm drives with adjustable backlash.
