GEARBOX REDUCERS
Correct angle gearboxes (worm and planetary) are tough and built for 90° turns. Inline reducers (parallel shaft and planetary) are an ideal match for motors with high input speeds, or when gearmotor performance is important. Get in touch with our technical sales personnel for help determining which gearbox alternative is best for you.
RIGHT ANGLE REDUCERS
WORM GEAR REDUCER
EP’s worm equipment reducers were created with a hollow bore and allow for a corner convert with optional dual result. The reducers can be found in 12 ratios ranging from 5:1 to 100:1, with non-back-drivable ratios 30:1 and higher. Our correct angle gearboxes were created with five mounting choices providing flexibility when incorporating the reducer into product.

These gearboxes are created to handle varying loads with little backlash. Planetary gear reducers operate more quietly than parallel shaft reducers. With 18 ratio options 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 a highly effective method for dissipating heat. Parallel shaft gearboxes have the shortest amount of our inline equipment reducer options so they work very well in conditions with limited space. Our parallel shaft gear reducers offer an affordable drop-in alternative solution for most small parallel shaft gearmotors.
Wormwheel gearboxes pass several names, including 90-degree gearboxes, right angle gearboxes, quickness reducers, worm equipment reducers and worm drive gearboxes. Gear reduction boxes include a gear arrangement in which a gear in the type of a screw, also called a worm, meshes with a worm equipment. These gears are typically created from bronze and the worms are metal or stainless steel.

While worm gears are similar to a spur equipment, the worm gearboxes are considerably smaller than other gear reduction boxes. A major benefit of worm gear reducers can be that they produce an output that’s 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 improve the path of the output, a left-hand thread worm gearbox is required.

Ever-Power EP series triple-reduction worm gear swiftness reducers are available 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 lbs. 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 can be found in four configurations: horizontal, vertical, shafted, and shaft installed.

These reducers are well suited for water/waste-water apparatus drive applications such as thickeners and clarifiers, which need a vertical 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 additional process or materials handling systems where huge torques/sluggish speeds are needed.

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

Enclosed Gears / Gearboxes
Enclosed gears, also referred to as gearboxes or swiftness reducers, are open gears within a housing. The housing facilitates bearings and shafts, retains in lubricants, and protects the elements from surrounding circumstances. Gearboxes are available in a wide range of load capacities and quickness ratios.

The objective 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 quickness reducer, the torque result will increase; if the drive boosts speed, the torque output will reduce. Gear drive selection factors include: shaft orientation, rate 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 rate reducer can achieve up to 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 a single begin worm, the worm equipment advances only one tooth for each 360-degree switch of the worm. So, regardless of the worm’s size, the apparatus ratio may be the ‘size of the worm equipment to 1′. Higher decrease ratios can be created by using double and triple decrease ratios.

Helical Gear Speed Reducers
Provide high-efficiency speed reduction through 1, 2, 3, or 4 sets of gears. Power can be transmitted from a high-speed pinion to a slower-speed equipment. Helical gears usually operate with their shafts parallel to one another. Both most common types will be the concentric (insight and output shafts are in series) and parallel shaft (insight and output shafts are offset). Single-stage helical equipment reducers are typically used for gear ratios up to about 8:1. Where lower speeds and higher ratios are required, dual, triple, and quadruple equipment reduction stages can be used.

worm reduction gearbox cycloidal Disc Speed Reducers
Different from conventional gearing because they operate without a high swiftness pinion or gear teeth, and the elements operate in compression rather than shear. This is because of the style of the cycloidal discs that roll within a ring gear housing, similar to a planetary design. The primary components will be the eccentric cam, the internally flanged result shaft, the discs, and the ring gear casing.

Three Mounting Options
(L-R) Bottom 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 possess a hollow output shaft that slips over the driven shaft.

A gearmotor combines a specific gearset with a engine. 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 insight and output shafts to retain essential oil and block dirt. The most commonly utilized type, the radial lip seal, contains a metal casing that fits in to the casing bore and an elastomeric sealing lip that presses on the shaft. Labyrinth seals are use for high-velocity applications, and contain a housing with some bands that limit leakage. A breather is usually a connect with a hole that is mounted in the apparatus housing allowing airflow and relieve internal pressure.

Lubrication
Enclosed gears are usually lubricated with oil. The most typical types of essential oil are rust and oxidation inhibiting, extreme pressure, compounded, and synthetic. Other styles consist of 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 means of substantially decreasing rate 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, particularly when the worm drive’s compactness is known as.

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