PARALLEL SHAFT GEARBOX
parallel-shaft-gearbox
Parallel shaft gearboxes will be the top choice for constant duty applications. Their gear cluster design provides an effective method for dissipating high temperature. Parallel shaft gearboxes possess the shortest length of our inline equipment reducer options therefore 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, rate reducers, worm gear reducers and worm drive gearboxes. Gear reduction boxes include a gear arrangement in which a equipment in the form of a screw, also referred to as a worm, meshes with a worm gear. These gears are usually made from bronze and the worms are metal or stainless steel.

While worm gears are similar to a spur gear, the worm gearboxes are significantly smaller than other gear reduction boxes. A main benefit of worm equipment reducers is certainly that they produce an output that is 90° from the input and can be used to transmit higher torque or decrease rotational speed. Frequently, a worm gearbox offers right hand threads; to change the direction of the output, a left-hands thread worm gearbox is necessary.

Ever-Power EP series triple-reduction worm gear acceleration reducers can be found in ratios from 5000:1 to 175,000:1 and center 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 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 mounted.

These reducers are ideal for water/waste-water apparatus drive applications such as for example thickeners and clarifiers, which require a vertical straight down shaft. Other offered 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 various other process or materials handling systems where large torques/slow speeds are needed.

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

Enclosed Gears / Gearboxes
Enclosed gears, also known as gearboxes or swiftness reducers, are open gears contained in a housing. The casing facilitates bearings and shafts, keeps in lubricants, and protects the elements from surrounding conditions. Gearboxes are available in an array of load capacities and acceleration 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 can be a rate reducer, the torque result increase; if the drive increases speed, the torque result will decrease. Gear drive selection factors include: shaft orientation, rate ratio, design type, nature of load, gear rating, 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 small package. Referred to as right angle drives, these consist of a cylindrical worm with screw threads and a worm. With a single start worm, the worm equipment advances only one tooth for each 360-degree switch of the worm. So, regardless of the worm’s size, the gear ratio may be the ‘size of the worm gear to 1′. Higher reduction ratios could be created through the use of double and triple reduction ratios.

Helical Gear Speed Reducers
Provide high-efficiency speed reduction through 1, 2, 3, or 4 sets of gears. Power is certainly transmitted from a high-rate pinion to a slower-speed equipment. Helical gears usually operate with their shafts parallel to each other. The two most common types are the concentric (input and output shafts are in range) and parallel shaft (input and output shafts are offset). Single-stage helical gear reducers are usually used for equipment ratios up to about 8:1. Where cheaper speeds and higher ratios are needed, dual, triple, and quadruple equipment reduction stages may be used.

Cycloidal Disc Speed Reducers
Different from conventional gearing because they operate without a high rate pinion or equipment teeth, and the elements operate in compression rather than shear. This is due to the design of the cycloidal discs that roll within a band gear housing, similar to a planetary design. The primary components are the eccentric cam, the internally flanged output shaft, the discs, and the ring gear casing.

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, will be the most common.

Shaft-mounted reducers possess a hollow output shaft that slips more than the driven shaft.

A gearmotor combines an enclosed 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 result shafts to retain essential oil and prevent dirt. The mostly used type, the radial lip seal, consists of a metal casing that fits in to the casing bore and an elastomeric sealing lip that presses on the shaft. Labyrinth seals are make use of for high-quickness applications, and contain a housing with some bands that limit leakage. A breather is a plug with a hole that’s mounted in the gear housing to permit 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 used for worm, planetary, cycloidal, and hypoidal reducers. Common distribution strategies are a splash system and a circulating system
Worm Reduction Gearbox Program:

Worm drives certainly are a compact method of substantially decreasing quickness and increasing torque. Small electric motors are usually 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 known as.

Worm drives are found in presses, in rolling mills, in conveying engineering, in mining industry devices, and on rudders. In addition, milling heads and rotary tables sit using high-precision duplex worm drives with adjustable backlash.
