Solitary reduction worm gearing provides high ratio reduction with few moving parts in a close-coupled compact drive. The proper angle arrangement of driving-to-driven machine requires a the least space. Input and result shafts can be prolonged in either or both directions in horizontal or vertical plans adaptable to any installation requirement. Efficient motor speeds are reduced to gradual 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 offers high efficiencies, and long service lifestyle. The hardened ground and polished alloy steel worm develops a simple, work hardened surface area on the bronze gear. Because of this worm gears wear in and improve with extented service while other gears are wearing out. Ever-Power offers a broad selection of model configurations, sizes, ratios, and add-ons from our standard products.
Fabricated Designs
If the application involves serious shock loads or possible housing damage from external sources (as in steel mills or mobile devices applications) Ever-Power can offer fabricated steel housings with up to a 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 units. Extra heavy part plates connect the worm and gear shaft bearing supports, assuring proper meshing of the apparatus under all load circumstances. 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 the application, be it a fresh project or a primary drop-in replacement for a competitor’s acceleration reducer. Fabricated metal reducers allow Ever-Power to complement a competitor’s footprint, centerline, and shaft elevation allowing a primary 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 design also includes a hardened, ground and polished alloy steel worm. This mixture develops a soft, work-hardened mating surface area of the bronze equipment which boosts with prolonged service.
Worm gearing is a course of gear reducers that utilizes correct angle, nonintersecting shafts. This form of reducer provides clean and quiet operation and allows for the possibility of large rate reductions. These gears can be found from stock in a wide selection of ratios, from as low as 4:1 up to 3600:1. The small design and structure allows worm equipment reducers to be positioned in a comparatively small space. Thus, high reductions in a limited package size can be achieved with this configuration. Our worm gear features the continuous sliding tooth action between worm and the teeth. This escalates the tolerance for large loads and shock loads. Worm gear drives offer users high reducing capacity for relatively low cost when compared to various 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 utilize worm gearing are: conveyors, mixers and bucket elevators.

A worm gear reducer is one kind of reduction gear package which consists of a worm pinion input, an output worm equipment, and features a right angle output orientation. This kind of reduction gear box is generally used to take a rated motor speed and create a low speed result with higher torque value based on the reduction ratio. They often times can solve space-saving problems since the worm equipment reducer is among the sleekest decrease gearboxes available due to the small diameter of its output gear.
worm gear reducerWorm equipment reducers are also a popular type of velocity reducer because they provide the greatest speed reduction in the tiniest package. With a higher ratio of speed decrease and high torque result multiplier, it’s unsurprising that lots of power transmission systems make use of a worm equipment reducer. Some of the most typical applications for worm gears are available in tuning instruments, medical examining equipment, elevators, protection 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 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 solid or hollow result shaft and show an adjustable mounting placement. Both the SW-1 and the SW-5, however, can withstand shock loading better than other decrease gearbox styles, making them well suited for demanding applications.

Worm Gear Reducers also called worm gearbox or worm speed reducers. Worm gear reducers are utilized for speed decrease and increasing the torque for electrical motor drives. You can decide to attach your NEMA electric motor to the reducer utilizing the NEMA C face flange or make use of a coupling. If you need a coupling for the output or input shaft see 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 the majority of worm gear manufactures.

Description
The HDR Series worm equipment reducers are found 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 models are 56C or 145TC flange mount with either right, still left 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 decrease and increased torque, with higher tolerances for shock loading than helical equipment reducers.
In order to decide on a gearbox speed reducer, you will have to determine the mandatory torque and service factor for the application form. Click on “Specifications” above for a table that will aid in determining the service element. For service elements above 1.0, multiply the mandatory torque by the provider factor.
