GEARBOX REDUCERS
Right 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. Get in touch with our technical sales personnel for help determining which gearbox solution is best for you.
RIGHT ANGLE REDUCERS
WORM GEAR REDUCER
EP’s worm gear reducers are designed with a hollow bore and invite for a corner convert with optional dual output. 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 are designed with five mounting options providing flexibility when incorporating the reducer into item.

Our inline planetary gearbox configurations provide the highest performance and best output torque of all our swiftness reducers. These gearboxes are made 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 continuous duty applications. Their equipment cluster design provides an effective method for dissipating high temperature. Parallel shaft gearboxes have the shortest amount of our inline equipment reducer options so they work very well in environments with limited space. Our parallel shaft gear reducers provide an affordable drop-in alternative solution for most small parallel shaft gearmotors.
Wormwheel gearboxes go by several names, including 90-degree gearboxes, right angle gearboxes, velocity reducers, worm equipment reducers and worm drive gearboxes. Gear reduction boxes include a gear arrangement in which a gear in the type of a screw, also known as 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 gear, the worm gearboxes are considerably smaller than other gear reduction boxes. A main benefit of worm equipment reducers can be that they create an output that is 90° from the input and can be utilized to transmit higher torque or reduce rotational speed. Frequently, a worm gearbox has right hand threads; to change the direction of the output, a left-hand thread worm gearbox is required.

Ever-Power EP series triple-reduction worm gear velocity reducers can be found 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 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 can be found in four configurations: horizontal, vertical, shafted, and shaft installed.
These reducers are well suited for water/waste-water devices drive applications such as for example thickeners and clarifiers, which require a vertical down shaft. Other obtainable configurations also make Ever-Power triple reduction reducers perfect for use on mixers, elevators, solar panels, astronomical telescopes, indexing tables, hoists, conveyors, or additional process or components handling systems where huge torques/slower 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 acceleration reducers, are open gears worm reduction gearbox within a housing. The casing facilitates bearings and shafts, keeps in lubricants, and protects the elements from surrounding conditions. Gearboxes can be found in an array of load capacities and acceleration ratios.
The purpose of a gearbox is to improve or reduce speed. As a result, torque output will be the inverse of the function. If the enclosed drive can be a rate reducer, the torque result will increase; if the drive boosts speed, the torque output will reduce. Gear drive selection elements include: shaft orientation, acceleration ratio, design type, character of load, gear ranking, environment, mounting position, operating temperature range, and lubrication.
Basic Types of Gearboxes
Worm Gear Speed Reducers
A single reduction swiftness reducer can achieve up to a 100:1 reduction ratio in a small package. Known 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 turn of the worm. So, regardless of the worm’s size, the apparatus ratio is the ‘size of the worm gear 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 pieces of gears. Power is transmitted from a high-acceleration pinion to a slower-speed equipment. Helical gears generally operate with their shafts parallel to each other. Both most common types will be the concentric (insight and output shafts are in line) and parallel shaft (insight and output shafts are offset). Single-stage helical equipment reducers are usually used for gear ratios up to about 8:1. Where cheaper speeds and higher ratios are necessary, double, triple, and quadruple equipment reduction stages may be used.
Cycloidal Disc Speed Reducers
Different from conventional gearing because they operate without a high swiftness pinion or gear teeth, and the parts operate in compression instead of shear. This is due to the design of the cycloidal discs that roll within a ring gear housing, similar to a planetary design. The main components are the eccentric cam, the internally flanged result 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 have a hollow output shaft that slips more than 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 the gear housing and insight and result shafts to retain oil and block dirt. The most commonly utilized type, the radial lip seal, contains a steel casing that fits into the housing bore and an elastomeric sealing lip that presses on the shaft. Labyrinth seals are use for high-velocity applications, and contain a housing with some bands that limit leakage. A breather is a plug with a hole that is mounted in the gear housing to permit airflow and relieve inner pressure.
Lubrication
Enclosed gears are usually lubricated with oil. The most common types of oil are rust and oxidation inhibiting, severe 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 program and a circulating system
Worm Reduction Gearbox Software:
Worm drives certainly 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 increases the range of applications that it may be suitable for, especially when the worm drive’s compactness is considered.
Worm drives are used in presses, in rolling mills, in conveying engineering, in mining industry devices, and on rudders. Furthermore, milling heads and rotary tables are positioned using high-precision duplex worm drives with adjustable backlash.
