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 insight speeds, or when gearmotor efficiency is important. Contact our technical sales staff for help determining which gearbox remedy is most beneficial for you.

Planetary equipment reducers operate more quietly than parallel shaft reducers. With 18 ratio choices which range 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 constant duty applications. Their equipment cluster design provides an effective method for dissipating heat. Parallel shaft gearboxes possess the shortest amount of our inline gear reducer options so they work well in environments with limited space. Our parallel shaft equipment reducers provide an affordable drop-in alternative solution for most small parallel shaft gearmotors.
Wormwheel gearboxes go by several names, including 90-degree gearboxes, right position gearboxes, swiftness reducers, worm gear 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 gear. These gears are typically made from bronze and the worms are steel 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 equipment reducers is certainly that they produce an output that is 90° from the input and can be used to transmit higher torque or decrease rotational speed. Frequently, a worm gearbox provides right hand threads; to change the direction of the output, a left-hands thread worm gearbox is required.

Enclosed Gears / Gearboxes
Enclosed gears, also known as gearboxes or rate reducers, are open gears contained in a housing. The housing supports bearings and shafts, keeps in lubricants, and protects the components from surrounding conditions. Gearboxes are available in an array of load capacities and velocity ratios.

The purpose of a gearbox is to improve or reduce speed. As a result, torque output would be the inverse of the function. If the enclosed drive can be a rate reducer, the torque output increase; if the drive raises speed, the torque output will decrease. Gear drive selection elements 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 acceleration reducer can achieve up to 100:1 reduction ratio in a little package. Referred to as right position 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 every 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 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-speed pinion to a slower-speed gear. 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 collection) 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 decrease speeds and higher ratios are needed, double, triple, and quadruple gear reduction stages may be used.

Cycloidal Disc Speed Reducers
Different from conventional gearing because they operate without a high acceleration pinion or equipment teeth, and the parts operate in compression rather than shear. This is because of the style of the cycloidal discs that roll within a ring gear housing, comparable to a planetary style. The main 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 an enclosed gearset with a engine. A motorized reducer resembles a gearmotor except that it is driven by a separate NEMA C-face motor.

Seals and Breathers
Seals are used between your gear housing and input and result shafts to retain oil and block dirt. The mostly utilized type, the radial lip seal, includes a metallic casing that fits in to the casing 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 rings that limit leakage. A breather is usually a plug with a hole that’s mounted in the gear housing to permit airflow and relieve internal pressure.

Lubrication
Enclosed gears are usually lubricated with oil. The most common types of 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 methods are a splash system and a circulating system
Worm Reduction Gearbox Program:

Worm drives certainly are a compact method of substantially decreasing quickness and increasing torque. Little 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 sector devices, and on rudders. Furthermore, worm reduction gearbox milling heads and rotary tables are positioned using high-precision duplex worm drives with adjustable backlash.
