GEARBOX REDUCERS
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 input speeds, or when gearmotor effectiveness is important. Get in touch with our technical sales personnel for help determining which gearbox remedy is best for you.

PARALLEL SHAFT GEARBOX
parallel-shaft-gearbox
Parallel shaft gearboxes will be the best choice for constant duty applications. Their equipment cluster design provides an effective method for dissipating heat. Parallel shaft gearboxes possess the shortest amount of our inline equipment reducer options so they work very well in conditions 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 position gearboxes, rate reducers, worm gear reducers and worm drive gearboxes. Gear reduction boxes feature a gear arrangement in which a gear in the form of a screw, also known as 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 are similar to a spur gear, the worm gearboxes are significantly smaller than other equipment reduction boxes. A main benefit of worm equipment reducers can be that they create an output that is 90° from the insight and can be utilized to transmit higher torque or reduce rotational speed. Frequently, a worm gearbox provides right hand threads; to change the direction of the output, a left-hands thread worm gearbox is required.

Ever-Power EP series triple-reduction worm gear velocity reducers are available in ratios from 5000:1 to 175,000:1 and middle 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 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 mounted.

These reducers are perfect for water/waste-water apparatus 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 make use of on mixers, elevators, solar power panels, astronomical telescopes, indexing tables, hoists, conveyors, or various other process or components handling systems where large torques/slower 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 called gearboxes or swiftness reducers, are open gears within a housing. The casing supports bearings and shafts, keeps in lubricants, and protects the components from surrounding circumstances. Gearboxes can be found in a wide variety of load capacities and speed ratios.

The objective of a gearbox is to improve or reduce speed. Because of this, torque output will be the inverse of the function. If the enclosed drive is definitely a swiftness reducer, the torque result will increase; if the drive improves speed, the torque output will decrease. Gear drive selection elements include: shaft orientation, rate 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 speed reducer can achieve up to 100:1 decrease ratio in a little package. Referred to as right position drives, these consist of a cylindrical worm with screw threads and a worm. With an individual 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 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 sets of gears. Power is usually transmitted from a high-rate pinion to a slower-speed gear. Helical gears generally operate with their shafts parallel to each other. The two most common types are the concentric (input and result shafts are in range) and parallel shaft (insight and output shafts are offset). Single-stage helical equipment reducers are usually used for equipment ratios up to about 8:1. Where lower speeds and higher ratios are required, dual, triple, and quadruple gear reduction stages may be used.

Cycloidal Disc Speed Reducers
Not the same as conventional gearing because they operate without a high quickness pinion or equipment teeth, and the parts operate in compression instead of shear. This is because of the design of the cycloidal discs that roll within a ring gear housing, comparable to a planetary design. The primary components will be 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, which have feet for bolting, are the most common.

Shaft-mounted reducers have 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 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 block dirt. The most commonly used type, the radial lip seal, includes a metallic casing that fits in to the housing bore and an elastomeric sealing lip that presses on the shaft. Labyrinth seals are use for high-rate applications, and contain a housing with some bands that limit leakage. A breather is definitely a connect with a hole that is mounted in the gear housing allowing airflow and relieve inner pressure.

Lubrication
Enclosed gears are usually lubricated with oil. The most common types of oil are rust and oxidation inhibiting, extreme 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 method of substantially decreasing velocity 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 may 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. In addition, milling heads and rotary tables are positioned using high-precision duplex worm drives with adjustable backlash.
