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 identifying which gearbox option is best for you.
RIGHT ANGLE REDUCERS

EP’s worm gear reducers are designed with a hollow bore and allow for a corner switch 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 are designed with five mounting options providing versatility when incorporating the reducer into item.

These gearboxes are designed to deal with varying loads with little 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 fit your needs.
PARALLEL SHAFT GEARBOX
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 have the shortest amount of our inline equipment reducer options so they work 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 go by several names, including 90-degree gearboxes, right position gearboxes, speed 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 known as a worm, meshes with a worm equipment. These gears are usually made from bronze and the worms are steel or stainless steel.
While worm gears act like a spur gear, the worm gearboxes are considerably smaller than other gear reduction boxes. A major benefit of worm equipment reducers is definitely that they generate an output that is 90° from the input and can be used to transmit higher torque or reduce rotational speed. Most often, a worm gearbox has right hand threads; to change the path of the output, a left-hands 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 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 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 mounted.
These reducers are perfect for water/waste-water equipment drive applications such as for example thickeners and clarifiers, which need a vertical down shaft. Other available 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 large torques/slow speeds are needed.
These reducers are also offered with a helical principal 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 supports bearings and shafts, retains in lubricants, and protects the components from surrounding conditions. Gearboxes are available in a wide 
range of load capacities and speed ratios.
The purpose 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 can be a swiftness reducer, the torque result increase; if the drive raises speed, the torque output will reduce. Gear drive selection elements include: shaft orientation, quickness 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 decrease 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 every 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 decrease through 1, 2, 3, or 4 units of gears. Power is certainly transmitted from a high-swiftness pinion to a slower-speed equipment. Helical gears usually operate with their shafts parallel to one another. Both most common types are the concentric (insight and result shafts are in range) and parallel shaft (insight and output shafts are offset). Single-stage helical gear reducers are usually used for equipment ratios up to about 8:1. Where reduce speeds and higher ratios are needed, double, triple, and quadruple gear reduction stages can be used.
Cycloidal Disc Speed Reducers
Different from conventional gearing because they operate with out a high acceleration pinion or equipment teeth, and the parts operate in compression instead of shear. This is because of the design 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 casing.
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 have a hollow output shaft that slips over the driven shaft.
A gearmotor combines a specific gearset with a motor. A motorized reducer resembles a gearmotor except that it’s driven by another 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 mostly utilized type, the radial lip seal, contains a metallic casing that fits into 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 some bands that limit leakage. A breather is certainly a connect with a hole that is mounted in the gear housing to permit airflow and relieve internal pressure.
Lubrication
Enclosed gears are usually lubricated with oil. The most typical types of 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 strategies are a splash program and a circulating system
Worm Reduction Gearbox Program:
Worm drives are a compact method of substantially decreasing velocity and increasing torque. Small electric motors are usually high-speed and low-torque; the addition of a worm drive increases the selection of applications that it might be suitable for, particularly when the worm drive’s compactness is considered.
Worm drives are found in presses, in rolling mills, in conveying engineering, in mining sector devices, and on rudders. In addition, milling heads and rotary tables are positioned using high-precision duplex worm drives with adjustable backlash.
