GEARBOX REDUCERS
Right angle gearboxes (worm and planetary) are durable and built for 90° turns. Inline reducers (parallel shaft and planetary) are a perfect match for motors with high input speeds, or when gearmotor performance is important. Get in touch with our technical sales personnel for help identifying which gearbox solution is best 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 which range 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 versatility when incorporating the reducer into item.

Planetary equipment reducers operate more quietly than parallel shaft reducers. With 18 ratio choices which range from 5:1 to 1000:1, we’ve a solution to fit your needs.
PARALLEL SHAFT GEARBOX
parallel-shaft-gearbox
Parallel shaft gearboxes will be the top choice for constant duty applications. Their gear cluster design provides a highly effective method for dissipating warmth. Parallel shaft gearboxes possess the shortest amount of our inline equipment reducer options therefore they work very well in environments with limited space. Our parallel shaft gear reducers offer an affordable drop-in substitute solution for most little parallel shaft gearmotors.
Wormwheel gearboxes go by several names, including 90-degree gearboxes, right angle gearboxes, rate reducers, worm equipment reducers and worm drive gearboxes. Gear decrease boxes include a gear arrangement when a gear in the form of a screw, also known as a worm, meshes with a worm equipment. These gears are usually 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 equipment reduction boxes. A principal benefit of worm gear reducers is definitely that they generate an output that’s 90° from the insight and can be used to transmit higher torque or decrease rotational speed. Most often, a worm gearbox has right hand threads; to change the path of the output, a left-hands thread worm gearbox is necessary.

Ever-Power EP series triple-reduction worm gear rate 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). Result torque ranges from 33,000 in lbs. 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 are available in four configurations: horizontal, vertical, shafted, and shaft installed.

These reducers are well suited for water/waste-water equipment drive applications such as thickeners and clarifiers, which require a vertical straight down shaft. Other obtainable configurations also make Ever-Power triple decrease reducers perfect for use on mixers, elevators, solar power panels, astronomical telescopes, indexing tables, hoists, conveyors, or other process or materials handling systems where huge torques/sluggish speeds are needed.

These reducers are also offered with a helical principal reduction stage and so are termed the HDVM series

Enclosed Gears / Gearboxes
Enclosed gears, also referred to as gearboxes or quickness reducers, are open gears within a housing. The casing facilitates bearings and shafts, holds in lubricants, and protects the elements from surrounding conditions. Gearboxes can be found in a wide selection of load capacities and quickness ratios.

The objective of a gearbox is to increase or reduce speed. Because of this, torque output will be the inverse of the function. If the enclosed drive is a speed reducer, the torque result will increase; if the drive improves speed, the torque result will decrease. Gear drive selection factors include: shaft orientation, quickness ratio, design type, character of load, gear ranking, environment, mounting position, operating 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 little package. Referred to as right position drives, these contain a cylindrical worm with screw threads and a worm. With an individual start worm, the worm equipment advances only 1 tooth for each 360-degree turn of the worm. So, regardless of the worm’s size, the apparatus ratio may be 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 reduction through 1, 2, 3, or 4 units of gears. Power is definitely transmitted from a high-acceleration pinion to a slower-speed equipment. Helical gears generally operate with their shafts parallel to each other. Both most common types will be the concentric (input and result shafts are in range) and parallel shaft (input and output shafts are offset). Single-stage helical gear reducers are typically used for gear ratios up to about 8:1. Where reduce speeds and higher ratios are necessary, dual, triple, and quadruple equipment reduction stages may be used.

worm reduction gearbox cycloidal Disc Speed Reducers
Not the same as conventional gearing because they operate with out a high speed pinion or gear teeth, and the components operate in compression rather than shear. This is because of the style of the cycloidal discs that roll within a band gear housing, similar to a planetary design. The main components are the eccentric cam, the internally flanged output 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 have 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’s driven by another NEMA C-face motor.

Seals and Breathers
Seals are used between the gear housing and insight and output shafts to retain essential oil and block dirt. The mostly used type, the radial lip seal, consists of a metal 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-velocity applications, and contain a housing with some bands that limit leakage. A breather can be a plug with a hole that is 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, intense 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 strategies are a splash program and a circulating system
Worm Reduction Gearbox Software:

Worm drives certainly are a compact method of substantially decreasing rate and increasing torque. Little electric motors are generally high-speed and low-torque; the addition of a worm drive increases the range of applications that it could be suitable for, especially when the worm drive’s compactness is considered.

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 high-precision duplex worm drives with adjustable backlash.
