worm gear speed reducer

Single reduction worm gearing provides high ratio reduction with few shifting parts in a close-coupled compact drive. The proper angle arrangement of driving-to-driven machine requires a minimum of space. Input and worm gear speed reducer result shafts can be extended in either or both directions in horizontal or vertical plans adaptable to any mounting requirement. Efficient engine speeds are decreased to slower speed requirements of several industrial machines in one reduction.

The exclusive utilization of the involute Helicoid Thread form (with departing side contact) on the worm and gear provides for high efficiencies, and long service lifestyle. The hardened surface and polished alloy steel worm develops a clean, work hardened surface area on the bronze equipment. Because of this worm gears put on in and improve with prolonged service while other gears are wearing out. Ever-Power offers a wide selection of model configurations, sizes, ratios, and accessories from our standard product line.
Fabricated Designs
If the application involves severe shock loads or possible housing damage from external sources (as in steel mills or mobile products applications) Ever-Power can provide fabricated steel housings with up to a 48″ center distances. Fabricated housings provide maximum rigidity and strength that allows the transmission of higher horsepower amounts than are feasible with standard cast iron models. Extra heavy part plates connect the worm and gear shaft bearing supports, assuring appropriate meshing of the apparatus under all load conditions. In smaller sizes, fabricated steel reducers are interchangeable with Ever-Power standard cast iron reducers.
Custom Designs
Ever-Power can offer custom swiftness and reversed engineered reducers for your application, be it a fresh project or a primary drop-in alternative to a competitor’s speed reducer. Fabricated steel reducers enable Ever-Power to match a competitor’s footprint, centerline, and shaft height allowing a direct drop-in alternative saving the client time and money.
Long – Quiet Life
All worm gears in Ever-Power reducers are produced from phosphorous bronze. Our style also includes a hardened, surface and polished alloy metal worm. This combination develops a clean, work-hardened mating surface of the bronze equipment which increases with prolonged service.
Worm gearing is a class of equipment reducers that utilizes right angle, nonintersecting shafts. This form of reducer provides smooth and quiet procedure and permits the possibility of large velocity reductions. These gears are available from share in a wide selection of ratios, from only 4:1 up to 3600:1. The small design and building allows worm gear reducers to be placed in a relatively small space. Thus, high reductions in a limited package size may be accomplished with this configuration. Our worm equipment features the constant sliding tooth actions between worm and one’s teeth. This escalates the tolerance for heavy loads and shock loads. Worm gear drives provide users high reducing convenience of relatively low cost in comparison with various other types of gearing.
The usage of worm gearing extends across many industries including food, beverage and grain and has many applications. Some applications that use worm gearing are: conveyors, mixers and bucket elevators.

A worm equipment reducer is one type of reduction gear box which consists of a worm pinion input, an output worm gear, and includes a right angle output orientation. This type of reduction gear package is normally used to take a rated motor speed and produce a low speed result with higher torque value based on the reduction ratio. They often can solve space-saving problems since the worm equipment reducer is among the sleekest decrease gearboxes available due to the little diameter of its result gear.
worm gear reducerWorm equipment reducers are also a popular type of acceleration reducer because they provide the greatest speed decrease in the tiniest package. With a higher ratio of speed decrease and high torque output multiplier, it’s unsurprising that lots of power transmission systems make use of a worm gear reducer. Some of the most typical applications for worm gears are available in tuning instruments, medical screening equipment, elevators, protection gates, and conveyor belts.
SW-1 and SW-5
Torque Transmission provides two sizes of worm gear reducer, the SW-1 and the SW-5 and both are available in a variety of ratios. The SW-1 ratios include 3.5:1 to 60:1 and the SW-5 ratios include 5:1 to 100:1. Both of these options are produced with durable compression-molded glass-fill polyester housings for a durable, long lasting, light weight speed reducer that’s also compact, noncorrosive, and nonmetallic.
Features
Our worm equipment reducers offer a choice of a good or hollow output shaft and show an adjustable mounting placement. Both SW-1 and the SW-5, however, can withstand shock loading much better than other reduction gearbox designs, making them ideal for demanding applications.

Worm Equipment Reducers also known as worm gearbox or worm acceleration reducers. Worm gear reducers are used for speed decrease and raising the torque for electrical engine drives. You can choose to attach your NEMA engine to the reducer utilizing the NEMA C face flange or use a coupling. If you need a coupling for the output or input shaft see our coupling section for selecting a coupling. You can expect four assemblies left hands and right hand and double result shaft and shaft insight and shaft result. Interchangeable with most worm gear manufactures. See data sheet in product overview for diamensions. If you don’t see your type, make sure you Contact Us.

Description
The HDR Series worm equipment reducers are used in low to moderate horsepower applications to reduce speeds and increase torque. Worm gear reducers can be found in direct or indirect drive, direct drive versions are 56C or 145TC flange attach with either right, remaining or dual result shafts or a hollow bore result. The indirect drive versions are shaft input-shaft output boxes for use with sprocket or pulley drive systems. They provide an effective low cost solution to speed reduction and increased torque, with higher tolerances for shock loading than helical gear reducers.
In order to select a gearbox speed reducer, you will have to determine the required torque and support factor for the application. Click on “Specs” above for a table that will assist in identifying the service factor. For service elements above 1.0, multiply the mandatory torque by the services factor.
