Single reduction worm gearing provides high ratio reduction with couple of shifting parts in a close-coupled compact drive. The proper angle arrangement of driving-to-driven machine requires a the least space. Input and output shafts can be prolonged in either or both directions in horizontal or vertical plans adaptable to any installation requirement. Efficient motor speeds are decreased to gradual speed worm gear speed reducer requirements of several industrial machines in one reduction.

The exclusive usage of the involute Helicoid Thread form (with leaving side contact) on the worm and gear provides for high efficiencies, and long service life. The hardened floor and polished alloy metal worm develops a clean, work hardened surface on the bronze gear. Because of this 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 add-ons 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 equipment applications) Ever-Power can provide fabricated steel housings with up to 48″ center distances. Fabricated housings provide optimum rigidity and strength that allows the tranny of higher horsepower amounts than are feasible with standard cast iron units. Extra heavy side plates connect the worm and equipment shaft bearing supports, assuring correct meshing of the apparatus under all load conditions. In smaller sized sizes, fabricated steel reducers are interchangeable with Ever-Power standard cast iron reducers.
Custom Designs
Ever-Power can offer custom speed and reversed engineered reducers for your application, be it a new project or a primary drop-in replacement for a competitor’s acceleration reducer. Fabricated metal reducers allow Ever-Power to match a competitor’s footprint, centerline, and shaft elevation allowing a direct drop-in alternative saving the customer time and money.
Long – Quiet Life
All worm gears in Ever-Power reducers are produced from phosphorous bronze. Our style also incorporates a hardened, surface and polished alloy steel worm. This combination develops a clean, work-hardened mating surface 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 even and quiet operation and allows for the probability of large acceleration reductions. These gears are available from share in a wide selection of ratios, from only 4:1 to as much as 3600:1. The compact design and structure allows worm equipment reducers to be positioned in a relatively small space. Thus, very high reductions in a limited package size can be achieved with this configuration. Our worm gear features the constant sliding tooth action between worm and the teeth. This escalates the tolerance for heavy loads and shock loads. Worm gear drives offer users high reducing capacity for relatively low cost when compared to some 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 use worm gearing are: conveyors, mixers and bucket elevators.

A worm gear reducer is one type of reduction gear box which consists of a worm pinion input, an output worm gear, and features a right angle result orientation. This type of reduction gear container is normally used to have a rated motor quickness and produce a low speed output with higher torque worth based on the decrease ratio. They often times can solve space-saving problems because the worm equipment reducer is among the sleekest decrease gearboxes available because of the little diameter of its output gear.
worm gear reducerWorm equipment reducers are also a favorite type of rate reducer because they offer the greatest speed reduction in the tiniest package. With a high ratio of speed reduction 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 common applications for worm gears can be found in tuning instruments, medical tests 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 can be found 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 manufactured with tough compression-molded glass-fill up polyester housings for a durable, long lasting, light-weight speed reducer that’s also compact, noncorrosive, and nonmetallic.
Features
Our worm equipment reducers offer an option of a solid or hollow result shaft and show an adjustable mounting position. Both the SW-1 and the SW-5, however, can withstand shock loading better than other reduction gearbox styles, making them perfect for demanding applications.

Worm Equipment Reducers also referred to as worm gearbox or worm speed reducers. Worm equipment reducers are used for speed reduction and increasing the torque for electric motor drives. You can decide to mount your NEMA motor to the reducer by using the NEMA C face flange or use a coupling. If you want a coupling for the output or input shaft discover our coupling section for choosing the coupling. We offer four assemblies left hand and right hand and double result shaft and shaft insight and shaft result. Interchangeable with many worm gear manufactures.

Description
The HDR Series worm gear 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 install with either right, remaining or dual output 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 priced solution 
to speed reduction and increased torque, with higher tolerances for shock loading than helical equipment 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 desk that will aid in identifying the service element. For service elements above 1.0, multiply the mandatory torque by the service factor.
Our standard 700 Series – the heart of Ever-Power speed reducer products – has been serving industry reliably for over 40 years. Its confirmed modular style has set the market standard for overall performance and may be the most imitated product in today’s worm gear quickness reducer market. But why settle for a knock-off when you can have the initial – from Ever-Power.
