Right angle gearboxes (worm and planetary) are tough and built for 90° turns. Inline reducers (parallel shaft and planetary) are an ideal match for motors with high input speeds, or when gearmotor efficiency is important. Get in touch with our technical sales personnel for help identifying which gearbox answer is best for you.
RIGHT ANGLE REDUCERS
WORM GEAR REDUCER
EP’s worm equipment reducers are designed with a hollow bore and invite for a corner turn 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 right angle gearboxes were created with five mounting choices 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 good and efficient correct angle configuration, our correct angle planetary gearboxes offer a robust solution. The right 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 small planetary gearbox configurations supply the smallest footprint and quietest operation of our acceleration reducers. These gearboxes are designed 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 have a solution to fit your needs. Our 52 frame size is also available with plastic gears for noise-sensitive applications.
INLINE PLANETARY GEARBOX
Our inline planetary gearbox configurations provide the highest performance and best output torque of most our speed reducers. These gearboxes are created to handle varying loads with little backlash. Planetary gear reducers operate more quietly than parallel shaft reducers. With 18 ratio options which range from 5:1 to 1000:1, we have a solution to suit your needs.
PARALLEL SHAFT GEARBOX
Parallel shaft gearboxes are the top choice for continuous duty applications. Their equipment cluster design provides an effective method for dissipating heat. Parallel shaft gearboxes have the shortest amount of our inline gear reducer options so they work well in conditions with limited space. Our parallel shaft gear reducers offer an affordable drop-in substitute solution for most small parallel shaft gearmotors.
Wormwheel gearboxes pass several names, including 90-degree gearboxes, right angle gearboxes, quickness reducers, worm gear reducers and worm drive gearboxes. Gear decrease boxes feature a gear arrangement in which a gear in the type of a screw, also called 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 significantly smaller than other gear reduction boxes. A principal benefit of worm equipment reducers is that they produce an output that is 90° from the insight and can be utilized to transmit higher torque or reduce rotational speed. Frequently, a worm gearbox has right hand threads; to improve 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). Result torque ranges from 33,000 in lbs. for the 7” CD EP-70 to 582,900 in pounds 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 installed.
These reducers are ideal for water/waste-water equipment drive applications such as for example thickeners and clarifiers, which require a vertical straight down shaft. Other available configurations also make Ever-Power triple reduction reducers perfect for make use of on mixers, elevators, solar panels, astronomical telescopes, indexing tables, hoists, conveyors, or additional process or materials handling systems where huge torques/gradual speeds are needed.
These reducers are also available with a helical major reduction stage and 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 housing facilitates bearings and shafts, holds in lubricants, and protects the elements from surrounding conditions. Gearboxes can be found in a wide variety of load capacities and quickness 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 speed reducer, the torque result increase; if the drive improves speed, the torque result will reduce. Gear drive selection factors include: shaft orientation, acceleration 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 rate reducer can achieve up to 100:1 decrease ratio in a little package. Referred to as right angle drives, these contain a cylindrical worm with screw threads and a worm. With a single start worm, the worm equipment advances only 1 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 decrease ratios can be created by using double and triple decrease ratios.
Helical Gear Speed Reducers
Provide high-efficiency speed reduction through 1, 2, 3, or 4 units of gears. Power is certainly transmitted from a high-velocity pinion to a slower-speed equipment. Helical gears usually operate with their shafts parallel to one another. The two most common types will be the concentric (insight and result shafts are in line) and parallel shaft (insight and output shafts are offset). Single-stage helical equipment reducers are typically used for gear ratios up to about 8:1. Where lower speeds and higher ratios are needed, dual, triple, and quadruple gear reduction stages can be used.
Cycloidal Disc Speed Reducers
Different from conventional gearing because they operate without a high quickness pinion or equipment teeth, and the components operate in compression rather than shear. This is because of 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 casing.
Three Mounting Options
(L-R) Base 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 possess a hollow output shaft that slips over the driven shaft.
A gearmotor combines a specific 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 insight and output shafts to retain essential oil and block dirt. The most commonly used type, the radial lip seal, contains a metal casing that fits into the casing bore and an elastomeric sealing lip that presses on the shaft. Labyrinth seals are use for high-velocity applications, and consist of a housing with some bands that limit leakage. A breather can be a plug with a hole that is mounted in the apparatus housing to permit airflow and relieve inner pressure.
Enclosed gears are generally lubricated with oil. The most typical types of oil are rust and oxidation inhibiting, extreme pressure, compounded, and synthetic. Other types consist of 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 Program:
Worm drives are a compact means of substantially decreasing acceleration and increasing torque. Little electric motors are usually high-speed and low-torque; the addition of a worm drive increases the range of applications that it might 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 sector machines, and on rudders. Furthermore, milling heads and rotary tables are positioned using high-precision duplex worm drives with adjustable backlash.
