RIGHT ANGLE REDUCERS
WORM GEAR REDUCER
EP’s worm gear reducers are designed with a hollow bore and invite for a corner convert 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 are designed with five mounting options providing versatility when incorporating the reducer into product.

PARALLEL SHAFT GEARBOX
Parallel shaft gearboxes will be the top choice for constant duty applications. Their gear cluster design provides a highly effective method for dissipating high temperature. Parallel shaft gearboxes possess the shortest amount of our inline equipment reducer options therefore they work very well in environments with limited space. Our parallel shaft equipment 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, rate reducers, worm equipment reducers and worm drive gearboxes. Gear reduction boxes include a gear arrangement in which a gear in the kind of a screw, also referred to as a worm, meshes with a worm equipment. These gears are usually worm reduction gearbox created from bronze and the worms are metal or stainless steel.
While worm gears are similar to a spur equipment, the worm gearboxes are significantly smaller than other gear reduction boxes. A main benefit of worm gear reducers is definitely that they generate an output that is 90° from the input and can be used to transmit higher torque or decrease rotational speed. Frequently, a worm gearbox has right hand threads; to change the path of the output, a left-hands thread worm gearbox is required.

Ever-Power EP series triple-reduction worm gear acceleration reducers are available in ratios from 5000:1 to 175,000:1 and middle distances from 7” to 20” (larger sizes on request). Output torque ranges from 33,000 in pounds. 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 installed.
These reducers are ideal 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 reduction reducers perfect for make use of on mixers, elevators, solar power panels, astronomical telescopes, indexing tables, hoists, conveyors, or various other process or components handling systems where large torques/gradual 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 acceleration reducers, are open gears contained in a housing. The casing supports bearings and shafts, holds in lubricants, and protects the parts from surrounding circumstances. Gearboxes are available in a wide variety of load capacities and velocity ratios.
The purpose of a gearbox is to improve or reduce speed. Because of this, torque output will be the inverse of the function. If the enclosed drive is definitely a speed reducer, the torque output increase; if the drive boosts speed, the torque result will decrease. Gear drive selection factors include: shaft orientation, velocity ratio, design type, nature of load, gear rating, environment, mounting position, working 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 little 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 1 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 by using double and triple reduction ratios.
Helical Gear Speed Reducers
Provide high-efficiency speed reduction through 1, 2, 3, or 4 pieces of gears. Power is certainly transmitted from a high-rate pinion to a slower-speed equipment. Helical gears generally operate with their shafts parallel to each other. Both most common types are the concentric (insight and output shafts are in range) and parallel shaft (input and output shafts are offset). Single-stage helical gear reducers are usually used for gear ratios up to about 8:1. Where decrease speeds and higher ratios are needed, dual, triple, and quadruple equipment reduction stages may be used.
Cycloidal Disc Speed Reducers
Not the same as conventional gearing because they operate without a high rate pinion or equipment teeth, and the parts operate in compression instead of shear. This is due to the design of the cycloidal discs that roll within a band gear housing, comparable to a planetary design. The primary components will be 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, which have feet for bolting, are the most common.
Shaft-mounted reducers have a hollow output shaft that slips over the driven shaft.
A gearmotor combines an enclosed gearset with a 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 the gear housing and input and result shafts to retain oil and block dirt. The most commonly utilized type, the radial lip seal, consists of a steel casing that fits in to the housing bore and an elastomeric sealing lip that presses on the shaft. Labyrinth seals are use for high-acceleration applications, and consist of a housing with a series of bands that limit leakage. A breather can be a plug with a hole that is mounted in the gear housing to permit airflow and relieve inner pressure.
Enclosed gears are usually 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 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, especially when the worm drive's compactness is considered.
Worm drives are found in presses, in rolling mills, in conveying engineering, in mining sector devices, and on rudders. In addition, milling heads and rotary tables sit using high-precision duplex worm drives with adjustable backlash.
