GEARBOX REDUCERS
Correct angle gearboxes (worm and planetary) are tough and built for 90° turns. Inline reducers (parallel shaft and planetary) are a perfect match for motors with high input speeds, or when gearmotor performance is important. Get in touch with our technical sales personnel for help identifying which gearbox solution is best for you.
RIGHT ANGLE REDUCERS
WORM GEAR REDUCER
EP’s worm equipment reducers are designed with a hollow bore and allow for a corner turn with optional dual output. 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 item.
RIGHT ANGLE BEVEL GEARBOX

Our inline planetary gearbox configurations supply the highest performance and best result torque of all our quickness reducers. These gearboxes are created to deal with varying loads with little 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 top choice for constant duty applications. Their gear cluster design provides an effective method for dissipating heat. Parallel shaft gearboxes have the shortest length of our inline gear reducer options so they work very well in conditions with limited space. Our parallel shaft gear reducers offer an affordable drop-in substitute solution for most small parallel shaft gearmotors.
Wormwheel gearboxes pass several names, including 90-degree gearboxes, right angle gearboxes, swiftness reducers, worm equipment reducers and worm drive gearboxes. Gear reduction boxes feature a gear arrangement in which a equipment in the type of a screw, also known as 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 act like a spur equipment, the worm gearboxes are considerably smaller than other gear reduction boxes. A major benefit of worm equipment reducers is certainly that they produce an output that’s 90° from the input 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 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 well suited for water/waste-water apparatus drive applications such as thickeners and clarifiers, which require a vertical down shaft. Other available 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/slower speeds are needed.
These reducers are also available with a helical main 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 swiftness ratios.
The objective of a gearbox is to increase or reduce speed. Because of this, torque output would be the inverse of the function. If the enclosed drive is a quickness reducer, the torque result increase; if the drive boosts speed, the torque result will reduce. 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 velocity reducer can achieve up to 100:1 decrease ratio in a little package. Referred to as right angle drives, these consist of a cylindrical worm with screw threads and a worm. With a single begin worm, the worm equipment advances only 1 tooth for every 360-degree switch of the worm. So, whatever 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 decrease 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. The two most common types will be the concentric (insight and result shafts are in series) 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 required, dual, triple, and quadruple equipment reduction stages can be used.
Cycloidal Disc Speed Reducers
Different from conventional gearing because they operate without a high acceleration pinion or equipment teeth, and the components 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, will be 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, includes 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-speed applications, and contain a housing with some bands that limit leakage. A breather is definitely a plug 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 common 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 program and a circulating system
Worm Reduction Gearbox Software:
Worm drives 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 may 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 market machines, and on rudders. In addition, milling heads and rotary tables are positioned using high-precision duplex worm drives with adjustable backlash.
