Solitary reduction worm gearing offers high ratio reduction with few moving parts in a close-coupled small 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 sluggish speed requirements of many industrial machines in a single 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 life. The hardened surface and polished alloy steel worm develops a even, work hardened surface area on the bronze gear. For this reason worm gears put on in and improve with prolonged service while other gears are deteriorating. Ever-Power offers a wide selection of model configurations, sizes, ratios, and accessories from our standard products.
Fabricated Designs
If the application involves severe shock loads or possible housing damage from external sources (as in steel mills or mobile apparatus applications) Ever-Power can offer fabricated steel housings with up to 48″ center distances. Fabricated housings provide optimum rigidity and strength which allows the tranny of higher horsepower amounts than are feasible with regular cast iron models. Extra heavy side plates connect the worm and equipment shaft bearing facilitates, assuring appropriate meshing of the apparatus under all load circumstances. In smaller sizes, fabricated metal reducers are interchangeable with Ever-Power regular cast iron reducers.
Custom Designs
Ever-Power can offer custom swiftness and reversed engineered reducers for the application, be it a fresh project or a direct drop-in replacement for a competitor’s acceleration reducer. Fabricated steel reducers allow Ever-Power to match a competitor’s footprint, centerline, and shaft elevation allowing a primary 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 design also incorporates a hardened, surface and polished alloy metal worm. This mixture develops a smooth, work-hardened mating surface area of the bronze equipment which increases with prolonged service.
Worm gearing is a course of equipment reducers that utilizes correct angle, nonintersecting shafts. This style of reducer provides easy and quiet procedure and permits the possibility of large swiftness reductions. These gears are available from share in a wide variety of ratios, from only 4:1 to as much as 3600:1. The small design and structure allows worm equipment reducers to be positioned in a comparatively small space. Thus, very high reductions in a restricted package size may be accomplished with this configuration. Our worm gear features the continuous sliding tooth action between worm and one’s teeth. This escalates the tolerance for heavy loads and shock loads. Worm gear drives offer users high reducing capacity for relatively low cost in comparison with various other types of gearing.
The use of worm gearing extends across many industries including food, beverage and grain and has many applications. Some applications that utilize worm gearing are: conveyors, mixers and bucket elevators.

A worm equipment reducer is one type of reduction gear box which contains a worm pinion insight, an output worm gear, and includes a right angle result orientation. This kind of reduction gear box is normally used to have a rated motor acceleration and create a low speed output with higher torque value based on the decrease ratio. They often can solve space-saving problems because the worm equipment reducer is among the sleekest reduction gearboxes available because of the little diameter of its result gear.
worm gear reducerWorm gear reducers are also a favorite type of rate reducer because they offer the greatest speed reduction in the smallest package. With a high ratio of speed decrease and high torque result 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 assessment equipment, elevators, security 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 these options are produced with rugged compression-molded glass-fill polyester housings for a durable, long lasting, light weight speed reducer that is also compact, noncorrosive, and nonmetallic.
Features
Our worm equipment reducers offer a choice of a solid or hollow result shaft and show an adjustable mounting position. Both the SW-1 and the SW-5, however, can endure shock loading better than other reduction gearbox styles, making them ideal for demanding applications.

Worm Gear Reducers also known as worm gearbox or worm speed reducers. Worm gear reducers are used for speed reduction and increasing the torque for electric powered engine drives. You can choose to attach your NEMA electric motor to the reducer by using the NEMA C encounter flange or use a coupling. If you want a coupling for the result or input shaft worm gear speed reducer observe our coupling section for selecting a coupling. We offer four assemblies left hand and right hand and double output shaft and shaft insight and shaft output. Interchangeable with the majority of worm gear manufactures.

Description
The HDR Series worm equipment reducers are used in low to moderate horsepower applications to reduce speeds and increase torque. Worm gear reducers are available in direct or indirect drive, direct drive versions are 56C or 145TC flange attach with either right, still left or dual result shafts or a hollow bore output. The indirect drive models are shaft input-shaft output boxes for use with sprocket or pulley drive systems. They provide an effective low priced solution to speed reduction and increased torque, with higher tolerances for shock loading than helical gear reducers.
In order to decide on a gearbox speed reducer, you will have to determine the required torque and services factor for the application form. Click on “Specifications” above for a desk that will aid in determining the service element. For service elements above 1.0, multiply the mandatory torque by the provider factor.
