Correct angle gearboxes (worm and planetary) are rugged and built for 90° turns. Inline reducers (parallel shaft and planetary) are an ideal match for motors with high insight speeds, or when gearmotor performance is important. Get in touch with our technical sales staff for help determining which gearbox remedy is most beneficial for you.
RIGHT ANGLE REDUCERS
WORM GEAR REDUCER
EP’s worm equipment reducers were created with a hollow bore and invite for a corner turn with optional dual result. 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 are designed with five mounting choices providing flexibility when incorporating the reducer into product.
RIGHT ANGLE BEVEL GEARBOX
The right angle bevel gearbox combines the top features of our right angle worm and planetary inline reducers. With a solid and efficient right angle configuration, our right angle planetary gearboxes provide a robust solution. The right angle bevel gearbox will come in 18 ratios ranging 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 supply the smallest footprint and quietest operation of our swiftness reducers. These gearboxes are made to manage varying loads with small backlash. With body 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 is also available with plastic-type gears for noise-delicate applications.
INLINE PLANETARY GEARBOX
Our inline planetary gearbox configurations provide the highest effectiveness and best output torque of all our velocity reducers. These gearboxes are designed to deal with varying loads with small backlash. Planetary gear reducers operate more quietly than parallel shaft reducers. With 18 ratio options which range from 5:1 to 1000:1, we’ve a solution to fit your needs.
PARALLEL SHAFT GEARBOX
Parallel shaft gearboxes will be the top choice for continuous duty applications. Their gear cluster design provides an effective method for dissipating warmth. Parallel shaft gearboxes possess the shortest length of our inline gear reducer options so they work well in environments with limited space. Our parallel shaft equipment reducers provide an affordable drop-in alternative solution for most little parallel shaft gearmotors.
Wormwheel gearboxes go by several names, including 90-degree gearboxes, right angle gearboxes, quickness reducers, worm equipment reducers and worm drive gearboxes. Gear decrease boxes include a gear arrangement when a equipment in the type of a screw, also called 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 considerably smaller than other equipment reduction boxes. A primary benefit of worm gear reducers is usually that they generate an output that’s 90° from the insight and can be used to transmit higher torque or decrease rotational speed. Frequently, a worm gearbox provides right hand threads; to change the path of the result, a left-hands thread worm gearbox is required.

GEAR RATIO 10:1
Ever-Power EP series triple-reduction worm gear speed reducers are available in ratios from 5000:1 to 175,000:1 and middle 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 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 mounted.
These reducers are ideal for water/waste-water apparatus drive applications such as thickeners and clarifiers, which require a vertical straight down shaft. Other available configurations also make Ever-Power triple decrease reducers perfect for use on mixers, elevators, solar panels, astronomical telescopes, indexing tables, hoists, conveyors, or other process or materials handling systems where huge torques/slower speeds are needed.
These reducers are also offered with a helical main reduction stage and so are termed the HDVM series
Enclosed Gears / Gearboxes
Enclosed gears, also referred to as gearboxes or speed reducers, are open gears contained in a housing. The housing facilitates bearings and shafts, keeps in lubricants, and protects the elements from surrounding circumstances. Gearboxes are available in a wide selection of load capacities and speed 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 is usually a quickness reducer, the torque output increase; if the drive boosts speed, the torque output will decrease. Gear drive selection elements include: shaft orientation, speed ratio, design type, character 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 a 100:1 decrease 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 start 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 gear to 1′. Higher decrease 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 sets of gears. Power is usually transmitted from a high-swiftness pinion to a slower-speed equipment. Helical gears generally operate with their shafts parallel to each other. The two most common types are the concentric (input and output shafts are in series) and parallel shaft (input and output shafts are offset). Single-stage helical equipment reducers are typically used for gear ratios up to about 8:1. Where reduce speeds and higher ratios are required, double, triple, and quadruple gear reduction stages may be used.
Cycloidal Disc Speed Reducers
Different from conventional gearing because they operate with out a high acceleration pinion or gear teeth, and the components operate in compression rather than shear. This is due to the design of the cycloidal discs that roll within a ring gear housing, comparable to a planetary design. 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, are the most common.
Shaft-mounted reducers possess 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 is driven by a separate NEMA C-face motor.
Seals and Breathers
Seals are used between the gear housing and input and output shafts to retain oil and prevent dirt. The most commonly utilized type, the radial lip seal, contains a steel casing that fits in to the housing bore and an elastomeric sealing lip that presses on the shaft. Labyrinth seals are use for high-swiftness applications, and contain a housing with some rings that limit leakage. A breather is a connect with a hole that’s mounted in the apparatus housing allowing airflow and relieve inner pressure.
Enclosed gears are generally lubricated with oil. The most typical types of essential oil are rust and oxidation inhibiting, intense pressure, compounded, and synthetic. Other types include grease and solid film. Grease can be utilized for worm, planetary, cycloidal, and hypoidal reducers. Common distribution methods are a splash system and a circulating system
Worm Reduction Gearbox Software:
Worm drives certainly are a compact means of substantially decreasing speed and increasing torque. Small electric motors are generally 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 found in presses, in rolling mills, in conveying engineering, in mining market machines, and on rudders. Furthermore, milling heads and rotary tables sit using high-precision duplex worm drives with adjustable backlash.
