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 efficiency is important. Get in touch with our technical sales personnel for help determining which gearbox answer 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 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 correct angle gearboxes are designed with five mounting choices providing versatility when incorporating the reducer into product.
RIGHT ANGLE BEVEL GEARBOX

Our inline planetary gearbox configurations provide the highest efficiency and best output torque of all our velocity reducers. These gearboxes are created to deal with varying loads with small backlash. Planetary equipment 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 fit your needs.
PARALLEL SHAFT GEARBOX
parallel-shaft-gearbox
Parallel shaft gearboxes are the top choice for constant duty applications. Their gear cluster design provides a highly effective method for dissipating warmth. Parallel shaft gearboxes have 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 replacement solution for most little parallel shaft gearmotors.
Wormwheel gearboxes pass several names, including 90-degree gearboxes, right angle gearboxes, acceleration reducers, worm equipment reducers and worm drive gearboxes. Gear reduction boxes include 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 significantly smaller than other equipment reduction boxes. A principal benefit of worm equipment reducers is certainly that they produce an output that is 90° from the insight and can be utilized to transmit higher torque or decrease rotational speed. Most often, 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 speed reducers can be found in ratios from 5000:1 to 175,000:1 and middle distances from 7” to 20” (larger sizes available on request). Output torque ranges from 33,000 in pounds. 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 can be found in four configurations: horizontal, vertical, shafted, and shaft installed.

These reducers are ideal for water/waste-water tools drive applications such as thickeners and clarifiers, which require a vertical straight down shaft. Other offered configurations also make Ever-Power triple decrease reducers perfect for use on mixers, elevators, solar panels, astronomical telescopes, indexing tables, hoists, conveyors, or additional process or materials handling systems where large torques/gradual speeds are needed.

These reducers are also available with a helical main reduction stage and are termed the HDVM series

Enclosed Gears / Gearboxes
Enclosed gears, also referred to as gearboxes or swiftness reducers, are open gears contained in a housing. The casing supports bearings and shafts, retains in lubricants, and protects the elements from surrounding conditions. Gearboxes are available in a wide variety of load capacities and speed ratios.

The objective of a gearbox is to improve or reduce speed. Consequently, torque output will be the inverse of the function. If the enclosed drive is certainly a quickness reducer, the torque result increase; if the drive increases speed, the torque output will decrease. Gear drive selection elements include: shaft orientation, swiftness 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 velocity reducer can achieve up to a 100:1 decrease ratio in a small package. Known as right angle drives, these contain a cylindrical worm with screw threads and a worm. With an individual begin worm, the worm equipment advances only one tooth for every 360-degree change of the worm. So, whatever the worm’s size, the apparatus ratio may be the ‘size of the worm gear to 1′. Higher decrease ratios could 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 pieces of gears. Power is usually transmitted from a high-rate pinion to a slower-speed equipment. Helical gears usually operate with their shafts parallel to each other. Both most common types are the concentric (insight and output shafts are in range) and parallel shaft (input and result shafts are offset). Single-stage helical equipment reducers are usually used for gear ratios up to about 8:1. Where decrease speeds and higher ratios are required, dual, 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 components operate in compression rather than shear. This is due to the style of the cycloidal discs that roll within a band gear housing, similar to a planetary design. The primary components will be 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, that 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 a specific gearset with a engine. 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 insight and result shafts to retain oil and prevent dirt. The mostly utilized type, the radial lip seal, consists of a steel 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 a plug with a hole that’s mounted in the apparatus housing allowing airflow and relieve inner 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 styles include grease and solid film. Grease can be utilized for worm, planetary, cycloidal, and hypoidal reducers. Common distribution strategies are a splash system and a circulating system
Worm Reduction Gearbox App:

Worm drives certainly are a compact method of substantially decreasing speed and increasing torque. Small electric motors are generally 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 found in presses, in rolling mills, in conveying engineering, in mining sector machines, and on rudders. In addition, milling heads and rotary tables sit using high-precision duplex worm drives with adjustable backlash.
