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

The exclusive usage of the involute Helicoid Thread form (with departing side contact) on the worm and gear provides for high efficiencies, and lengthy service existence. The hardened surface and polished alloy steel worm develops a soft, work hardened surface area on the bronze gear. Because of this worm gears put on in and improve with prolonged service while additional gears are wearing out. Ever-Power offers a broad 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 tranny of higher horsepower amounts than are feasible with regular cast iron models. Extra heavy aspect plates connect the worm and equipment shaft bearing supports, assuring appropriate meshing of the apparatus under all load circumstances. In smaller sized sizes, fabricated steel reducers are interchangeable with Ever-Power standard cast iron reducers.
Custom Designs
Ever-Power can offer custom quickness and reversed engineered reducers for your application, be it a new project or a direct drop-in replacement for a competitor’s velocity reducer. Fabricated steel reducers enable Ever-Power to complement a competitor’s footprint, centerline, and shaft height allowing a direct drop-in substitute saving the client time and money.
Long – Quiet Life
All worm gears in Ever-Power reducers are manufactured from phosphorous bronze. Our style also includes a hardened, ground and polished alloy steel worm. This combination develops a easy, work-hardened mating surface area of the bronze gear which improves with prolonged service.
Worm gearing is a class of gear reducers that utilizes right angle, nonintersecting shafts. This form of reducer provides easy and quiet procedure and permits the possibility of large velocity reductions. These gears can be found 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 positioned in a relatively small space. Thus, very 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 the teeth. This increases the tolerance for heavy loads and shock loads. Worm gear drives provide users high reducing convenience of relatively low cost in comparison with some other types of gearing.
The utilization of worm gearing extends across many industries including food, beverage and grain and has many applications. Some applications that make use of worm gearing are: conveyors, mixers and bucket elevators.

-Worm Shaft: Manufactured with Carbon alloyed Steel S45C or SCM415, precison machined and carburized to HRC45 or HRC60, after that for precision tooth grinding to ensure maximum contacting.
-Worm Wheel: Manufactured with Carbon alloy ALBC2, teeth are machined by precision CNC hobbing machine to sustain high impact.
A worm equipment reducer is one type of reduction gear box which consists of a worm pinion input, an output worm equipment, and includes a right angle output orientation. This type of reduction gear box is normally used to have a rated motor velocity 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 gear reducer is one of the sleekest reduction gearboxes available due to the little diameter of its result gear.
worm gear reducerWorm equipment reducers are also a popular type of swiftness reducer because they provide the greatest speed decrease in the smallest package. With a high ratio of speed decrease and high torque output multiplier, it’s unsurprising that lots of power transmission systems utilize 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 offers 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 is also compact, non-corrosive, and nonmetallic.
Features
Our worm gear reducers offer a choice of a good or hollow output shaft and show an adjustable mounting position. Both SW-1 and the SW-5, however, can withstand shock loading better than other reduction gearbox designs, making them perfect for demanding applications.

Worm Equipment Reducers also known as worm gearbox or worm rate reducers. Worm gear reducers are utilized for speed reduction and raising the torque for electrical engine drives. You can choose to mount your NEMA engine to the reducer utilizing the NEMA C encounter 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 hand and right hand and double result shaft and shaft input and shaft output. Interchangeable with most worm gear manufactures. See data sheet in product overview for diamensions. If you don’t see your type, please Contact Us.

Description
The HDR Series worm equipment reducers are used in low to moderate horsepower applications to lessen 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 output. The indirect drive versions are shaft input-shaft result boxes for use with sprocket or pulley drive systems. They provide an effective low cost solution to speed decrease 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 service factor for the application. Click on “Specs” above for a table that will assist in identifying the service element. For service elements above 1.0, multiply the mandatory torque by the assistance factor.
