GEARBOX REDUCERS
Correct 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 efficiency is important. Get in touch with our technical sales personnel for help identifying which gearbox remedy is best for you.

PARALLEL SHAFT GEARBOX
parallel-shaft-gearbox
Parallel shaft gearboxes are the top choice for continuous duty applications. Their equipment cluster design provides an effective method for dissipating temperature. Parallel shaft gearboxes possess the shortest length of our inline gear reducer options so they work very well in conditions with limited space. Our parallel shaft equipment 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 position gearboxes, velocity reducers, worm gear reducers and worm drive gearboxes. Gear reduction boxes include a gear arrangement when a equipment in the kind of a screw, also known as a worm, meshes with a worm gear. These gears are typically made from bronze and the worms are metal or stainless steel.

While worm gears act like a spur gear, the worm gearboxes are considerably smaller than other equipment reduction boxes. A primary benefit of worm gear reducers can be that they generate an output that’s 90° from the input and can be utilized to transmit higher torque or reduce rotational speed. Most often, a worm gearbox provides right hand threads; to change the path of the result, 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 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 insight 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 gear drive applications such as for example thickeners and clarifiers, which need a vertical straight down shaft. Other obtainable configurations also make Ever-Power triple decrease reducers perfect for make use of on mixers, elevators, solar panels, astronomical telescopes, indexing tables, hoists, conveyors, or other process or materials handling systems where large torques/slower speeds are needed.

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

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

The purpose of a gearbox is to increase or reduce speed. Consequently, torque output will be the inverse of the function. If the enclosed drive is definitely a speed reducer, the torque result increase; if the drive raises speed, the torque result will decrease. Gear drive selection factors include: shaft orientation, rate ratio, design type, nature of load, gear ranking, environment, mounting position, operating temperature range, and lubrication.

Basic Types of Gearboxes

Worm Gear Speed Reducers
A single reduction rate reducer can achieve up to 100:1 reduction ratio in a little package. Known as right angle drives, these consist of a cylindrical worm with screw threads and a worm. With a single begin worm, the worm gear 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 equipment to 1′. Higher decrease ratios can be created by using double and triple reduction 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-speed 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 output shafts are in line) and parallel shaft (insight and output shafts are offset). Single-stage helical equipment reducers are usually used for gear ratios up to about 8:1. Where lower speeds and higher ratios are needed, double, triple, and quadruple gear reduction stages can be used.

Cycloidal Disc Speed Reducers
Not the same as conventional gearing because they operate without a high velocity pinion or gear teeth, and the components operate in compression instead of shear. This is because of the style of the cycloidal discs that roll within a ring gear housing, comparable to a planetary design. The primary components are the eccentric cam, the internally flanged output shaft, the discs, and the ring gear housing.

Three Mounting Options
(L-R) Base 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 electric 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 your gear housing and input and output shafts to retain essential oil and prevent dirt. The mostly used type, the radial lip seal, consists of a metallic 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-speed applications, and consist of a housing with some bands that limit leakage. A breather is definitely a connect with a hole that is mounted in the apparatus housing to permit airflow and relieve internal pressure.

Lubrication
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 include grease and solid film. Grease can be utilized for worm, planetary, cycloidal, and hypoidal reducers. Common distribution methods are a splash program and a circulating system
Worm Reduction Gearbox Software:

Worm drives are a compact method of substantially decreasing acceleration and increasing torque. Small electric motors are usually high-speed and low-torque; the addition of a worm drive escalates the range of applications that it could be suitable for, specially when the worm drive’s compactness is known as.

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