GEARBOX REDUCERS
Right angle gearboxes (worm and planetary) are rugged and built for 90° turns. Inline reducers (parallel shaft and planetary) are a perfect match for motors with high insight speeds, or when gearmotor effectiveness is important. Get in touch with our technical sales personnel for help determining which gearbox option 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 turn with optional dual output. 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 right angle gearboxes were created with five mounting options providing versatility when incorporating the reducer into item.

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 are the top choice for constant duty applications. Their equipment cluster design provides an effective method for dissipating warmth. Parallel shaft gearboxes have the shortest amount of our inline gear reducer options therefore they work well in environments with limited space. Our parallel shaft equipment reducers provide an affordable drop-in replacement solution for most small parallel shaft gearmotors.
Wormwheel gearboxes pass several names, including 90-degree gearboxes, right angle gearboxes, rate reducers, worm gear reducers and worm drive gearboxes. Gear decrease boxes include a gear arrangement when a gear in the kind of a screw, also referred to as a worm, meshes with a worm equipment. These gears are typically made from bronze and the worms are steel or stainless steel.
While worm gears act like a spur equipment, the worm gearboxes are significantly smaller than other gear reduction boxes. A primary benefit of worm equipment reducers is that they create an output that’s 90° from the input and can be used to transmit higher torque or decrease rotational speed. Most often, a worm gearbox offers right hand threads; to improve the path of the result, a left-hand thread worm gearbox is required.

These reducers are also offered with a helical primary reduction stage and are termed the HDVM series
Enclosed Gears / Gearboxes
Enclosed gears, also referred to as gearboxes or velocity reducers, are open gears within a housing. The housing facilitates bearings and shafts, keeps in lubricants, and protects the components from surrounding conditions. Gearboxes can be found in a wide range of load capacities and velocity ratios.
The purpose of a gearbox is to increase or reduce speed. Because of this, torque output would be the inverse of the function. If the enclosed drive is certainly a quickness reducer, the torque output will increase; if the drive boosts speed, the torque result will decrease. Gear drive selection elements include: shaft orientation, acceleration ratio, design type, character of load, gear ranking, 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 a 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 begin worm, the worm equipment advances only one tooth for every 360-degree convert of the worm. So, regardless of the worm’s size, the apparatus ratio may be 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 can be transmitted from a high-velocity 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 (input and output shafts are in line) and parallel shaft (input and output shafts are offset). Single-stage helical gear reducers are usually used for gear ratios up to about 8:1. Where reduce speeds and higher ratios are required, double, triple, and quadruple equipment reduction stages may be used.
Cycloidal Disc Speed Reducers
Different from conventional gearing because they operate without a high speed 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 style. The main components will be the eccentric cam, the internally flanged result shaft, the discs, and the ring gear housing.
Three Mounting Options
(L-R) Foundation 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 an enclosed 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 input and output shafts to retain essential oil and block dirt. The most commonly utilized type, the radial lip seal, consists of a metallic casing that fits into the housing bore and an elastomeric sealing lip that presses on the shaft. Labyrinth seals are make use of for high-swiftness applications, and consist of a housing with some bands that limit leakage. A breather is usually a connect 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 essential oil are rust and oxidation inhibiting, extreme pressure, compounded, and synthetic. Other types 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 Program:
Worm drives certainly are a compact means of substantially decreasing speed and increasing torque. Little 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 market devices, and on rudders. In addition, milling heads and rotary tables sit using worm reduction gearbox high-precision duplex worm drives with adjustable backlash.
