Single reduction worm gearing provides high ratio reduction with couple of moving parts in a close-coupled compact drive. The proper angle set up of driving-to-driven machine requires a minimum of space. Input and output shafts can be prolonged in either or both directions in horizontal or vertical arrangements adaptable to any installation requirement. Efficient engine speeds are decreased to slow speed requirements of several industrial machines in one reduction.

The exclusive use of the involute Helicoid Thread form (with leaving 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 soft, work hardened surface area on the bronze gear. Because of this worm gears put on in and improve with extented service while other gears are wearing out. Ever-Power offers a wide selection of model configurations, sizes, ratios, and components from our standard product line.
Fabricated Designs
If your application involves serious shock loads or possible housing damage from external sources (as in steel mills or mobile tools applications) Ever-Power can offer fabricated steel housings with up to 48″ center distances. Fabricated housings provide optimum rigidity and strength which allows the transmission of higher horsepower amounts than are feasible with regular cast iron models. Extra heavy aspect 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 standard cast iron reducers.
Custom Designs
Ever-Power can provide custom rate 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 metal reducers allow Ever-Power to match a competitor’s footprint, centerline, and shaft height 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 design also includes a hardened, floor and polished alloy metal worm. This combination develops a simple, work-hardened mating surface area of the bronze gear which boosts with prolonged service.
Worm gearing is a course of gear reducers that utilizes right angle, nonintersecting shafts. This style of worm gear speed reducer reducer provides even and quiet operation and permits the possibility of large rate reductions. These gears are available from stock in a wide variety of ratios, from as low as 4:1 up to 3600:1. The compact design and building allows worm gear reducers to be positioned in a comparatively small space. Thus, very high reductions in a limited package size may be accomplished with this configuration. Our worm gear features the constant sliding tooth action between worm and the teeth. This escalates the tolerance for large loads and shock loads. Worm gear drives provide users high reducing capacity for relatively low cost when compared to some 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 utilize worm gearing are: conveyors, mixers and bucket elevators.

A worm gear reducer is one type of reduction gear container which includes 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 produce a low speed result with higher torque value based on the reduction ratio. They often times can solve space-saving problems since the worm gear reducer is among the sleekest reduction gearboxes available because of the little diameter of its result gear.
worm gear reducerWorm equipment reducers are also a favorite type of rate reducer because they provide the greatest speed reduction in the smallest package. With a high ratio of speed reduction 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 common applications for worm gears are available in tuning instruments, medical tests equipment, elevators, security gates, and conveyor belts.
SW-1 and SW-5
Torque Transmission offers two sizes of worm equipment reducer, the SW-1 and the SW-5 and both are available in a range 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 manufactured with tough 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 placement. Both the SW-1 and the SW-5, however, can endure shock loading better than other decrease gearbox styles, making them ideal for demanding applications.

Worm Gear Reducers also referred to as worm gearbox or worm quickness reducers. Worm gear reducers are used for speed decrease and increasing the torque for electrical engine drives. You can choose to mount your NEMA engine to the reducer by using the NEMA C face flange or use a coupling. If you need a coupling for the result or input shaft observe our coupling section for choosing the coupling. We offer four assemblies left hands and right hand and double result shaft and shaft input and shaft output. Interchangeable with most worm gear manufactures. Observe data sheet in product overview for diamensions. Unless you see your type, make sure you Contact Us.

Description
The HDR Series worm gear 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 output. The indirect drive versions are shaft input-shaft output boxes for make use of 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 equipment reducers.
In order to select a gearbox speed reducer, you will need to determine the mandatory torque and services factor for the application form. Click on “Specifications” above for a desk that will aid in determining the service factor. For service elements above 1.0, multiply the mandatory torque by the provider factor.
