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 effectiveness is important. Get in touch with our technical sales staff for help identifying which gearbox option is best for you.

These gearboxes are designed to deal with varying loads with small backlash. Planetary gear reducers operate more quietly than parallel shaft reducers. With 18 ratio choices ranging from 5:1 to 1000:1, we’ve a solution to suit your needs.
PARALLEL SHAFT GEARBOX
parallel-shaft-gearbox
Parallel shaft gearboxes are the best choice for continuous duty applications. Their gear cluster design provides an effective method for dissipating warmth. Parallel shaft gearboxes possess the shortest length of our inline equipment reducer options therefore they work well in conditions with limited space. Our parallel shaft gear reducers provide an affordable drop-in substitute solution for most little parallel shaft gearmotors.
Wormwheel gearboxes pass several names, including 90-degree gearboxes, right angle gearboxes, speed reducers, worm equipment reducers and worm drive gearboxes. Gear decrease boxes feature a gear arrangement when a equipment in the kind of a screw, also referred to as a worm, meshes with a worm gear. These gears are typically created from bronze and the worms are steel or stainless steel.

While worm gears act like a spur gear, the worm gearboxes are significantly smaller than other gear reduction boxes. A principal benefit of worm gear reducers is that they create an output that is 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 improve the direction of the output, a left-hands thread worm gearbox is required.

Ever-Power EP series triple-reduction worm gear rate reducers can be found in ratios from 5000:1 to 175,000:1 and center distances from 7” to 20” (larger sizes on request). Result torque ranges from 33,000 in pounds. for the 7” CD EP-70 to 582,900 in pounds 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 perfect for water/waste-water devices drive applications such as for example thickeners and clarifiers, which require a vertical 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 materials handling systems where large torques/slow speeds are needed.

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

Enclosed Gears / Gearboxes
Enclosed gears, also called gearboxes or acceleration reducers, are open gears contained in a housing. The housing facilitates bearings and shafts, retains in lubricants, and protects the parts from surrounding conditions. Gearboxes can be found in an array of load capacities and acceleration ratios.

The purpose of a gearbox is to improve or reduce speed. Consequently, torque output will be the inverse of the function. If the enclosed drive is a swiftness reducer, the torque output increase; if the drive boosts speed, the torque output will reduce. Gear drive selection elements include: shaft orientation, acceleration ratio, design type, character 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 reduction ratio in a little package. Known as right position drives, these consist of a cylindrical worm with screw threads and a worm. With an individual begin worm, the worm equipment advances only 1 tooth for every 360-degree convert of the worm. So, whatever the worm’s size, the gear ratio may be the ‘size of the worm gear to 1′. Higher reduction ratios can be created by using double and triple decrease ratios.

Helical Gear Speed Reducers
Provide high-efficiency speed decrease through 1, 2, 3, or 4 sets of gears. Power is transmitted from a high-velocity pinion to a slower-speed equipment. Helical gears usually operate with their shafts parallel to one another. The two most common types will be the concentric (input and output shafts are in range) and parallel shaft (input and result shafts are offset). Single-stage helical equipment 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 can be used.

Cycloidal Disc Speed Reducers
Not the same as conventional gearing because they operate without a high swiftness pinion or equipment teeth, and the elements operate in compression instead of shear. This is due to the style of the cycloidal discs that roll within a ring gear housing, similar to a planetary style. The primary components are the eccentric cam, the internally flanged result 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, which 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 electric motor. A motorized reducer resembles a gearmotor except that it is driven by another NEMA C-face motor.

Seals and Breathers
Seals are used between your gear housing and insight and result shafts to retain essential oil and prevent dirt. The most commonly utilized type, the radial lip seal, contains 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-quickness applications, and consist of a housing with some rings that limit leakage. A breather can be a connect with a hole that is mounted in the gear housing to permit airflow and relieve inner pressure.

Lubrication
Enclosed gears are usually lubricated with oil. The most typical types of oil are rust and oxidation inhibiting, intense 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 Application:

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

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