RIGHT ANGLE REDUCERS
WORM GEAR REDUCER
EP’s worm gear reducers are worm reduction gearbox designed with a hollow bore and allow for a corner switch with optional dual result. 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 options providing flexibility when incorporating the reducer into product.
RIGHT ANGLE BEVEL GEARBOX
The proper angle bevel gearbox combines the features of our right angle worm and planetary inline reducers. With a solid and efficient right angle configuration, our correct angle planetary gearboxes provide a robust solution. The proper angle bevel gearbox comes in 18 ratios which range from 5:1 to 1000:1, in fact it is back-drivable at all ratios.
I-SERIES PLANETARY GEARBOX
Our I-Series little planetary gearbox configurations provide the smallest footprint and quietest operation of our quickness reducers. These gearboxes are made to deal with varying loads with small backlash. With frame 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 performance and best output torque of most our acceleration 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 options ranging from 5:1 to 1000:1, we have a solution to suit your needs.
PARALLEL SHAFT GEARBOX
Parallel shaft gearboxes are 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 length of our inline gear reducer options so they work well in conditions 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 position gearboxes, quickness reducers, worm gear reducers and worm drive gearboxes. Gear reduction boxes feature a gear arrangement in which a equipment in the kind of a screw, also called a worm, meshes with a worm gear. These gears are typically made from bronze and the worms are steel or stainless steel.
While worm gears are similar to a spur equipment, the worm gearboxes are considerably smaller than other gear reduction boxes. A main benefit of worm equipment reducers is certainly that they produce an output that is 90° from the input and can be utilized to transmit higher torque or reduce rotational speed. Frequently, a worm gearbox offers right hand threads; to improve the direction of the result, a left-hand thread worm gearbox is required.

These reducers are also obtainable with a helical main reduction stage and are termed the HDVM series
Enclosed Gears / Gearboxes
Enclosed gears, also called gearboxes or rate reducers, are open gears contained in a housing. The housing supports bearings and shafts, retains in lubricants, and protects the components from surrounding circumstances. Gearboxes are available in an array of load capacities and rate ratios.
The purpose of a gearbox is to improve or reduce speed. As a result, torque output would be the inverse of the function. If the enclosed drive is definitely a acceleration reducer, the torque output increase; if the drive boosts speed, the torque output will reduce. Gear drive selection elements 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 rate reducer can achieve up to 100:1 reduction ratio in a small package. Known as right angle drives, these consist of a cylindrical worm with screw threads and a worm. With a single begin worm, the worm gear advances only one tooth for every 360-degree switch of the worm. So, whatever the worm’s size, the gear ratio is the ‘size of the worm equipment to 1′. Higher reduction ratios could be created by using double and triple reduction ratios.
Helical Gear Speed Reducers
Provide high-efficiency speed decrease through 1, 2, 3, or 4 pieces of gears. Power is certainly transmitted from a high-speed pinion to a slower-speed gear. Helical gears usually operate with their shafts parallel to one another. The two most common types are the concentric (insight and output shafts are in line) and parallel shaft (insight and result shafts are offset). Single-stage helical equipment reducers are usually used for equipment ratios up to about 8:1. Where decrease 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 without a high acceleration pinion or equipment teeth, and the elements operate in compression instead of shear. This is due to the design of the cycloidal discs that roll within a ring gear housing, comparable to a planetary style. The primary components are the eccentric cam, the internally flanged result 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, 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 an enclosed gearset with a electric 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 your gear housing and input and result shafts to retain oil and prevent dirt. The most commonly utilized type, the radial lip seal, contains a metallic casing that fits in to the casing bore and an elastomeric sealing lip that presses on the shaft. Labyrinth seals are use for high-swiftness applications, and consist of a housing with a series of rings that limit leakage. A breather is usually a connect with a hole that’s mounted in the gear housing to permit airflow and relieve internal pressure.
Enclosed gears are usually lubricated with oil. The most typical types of oil are rust and oxidation inhibiting, extreme 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 system and a circulating system
Worm Reduction Gearbox App:
Worm drives are a compact means of substantially decreasing speed and increasing torque. Small electric motors are usually high-speed and low-torque; the addition of a worm drive escalates the selection of applications that it might be suitable for, particularly when the worm drive’s compactness is known as.
Worm drives are found in presses, in rolling mills, in conveying engineering, in mining industry machines, and on rudders. Furthermore, milling heads and rotary tables are positioned using high-precision duplex worm drives with adjustable backlash.
