Solitary reduction worm gearing offers high ratio reduction with few moving parts in a close-coupled small 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 mounting requirement. Efficient electric motor speeds are reduced to gradual speed requirements of many industrial machines in a single reduction.

The exclusive use of the involute Helicoid Thread form (with leaving side contact) on the worm and gear provides for high efficiencies, and lengthy service life. The hardened surface and polished alloy metal worm develops a soft, work hardened surface area on the bronze gear. For this reason worm gears use in and improve with extented service while various other gears are wearing out. EP offers a wide collection of model configurations, sizes, ratios, and add-ons from our standard product line.
Fabricated Designs
If the application involves serious shock loads or feasible housing damage from external sources (as in steel mills or mobile devices applications) EP can provide fabricated steel housings with up to 48″ center distances. Fabricated housings provide optimum rigidity and strength which allows the tranny of higher horsepower levels than are possible with standard cast iron systems. Extra heavy side plates connect the worm and gear shaft bearing supports, assuring appropriate meshing of the apparatus under all load conditions. In smaller sized sizes, fabricated steel reducers are interchangeable with EP standard cast iron reducers.
Custom Designs
EP can offer custom rate and reversed engineered reducers for your application, be it a fresh project or a direct drop-in replacement for a competitor’s swiftness reducer. Fabricated metal reducers allow EP to complement a competitor’s footprint, centerline, and shaft height allowing a direct drop-in alternative saving the client time and money.
Long – Quiet Life
All worm gears in EP reducers are produced from phosphorous bronze. Our style also includes a hardened, floor and polished alloy metal worm. This combination develops a simple, work-hardened mating surface of the bronze equipment which enhances with prolonged service.
Worm gearing is a course of gear reducers that utilizes correct angle, nonintersecting shafts. This form of reducer provides simple and quiet procedure and permits the possibility of large rate reductions. These gears can be found from share in a wide selection of ratios, from as low as 4:1 to as much as 3600:1. The compact design and structure allows worm equipment reducers to be positioned in a comparatively small space. Thus, very high reductions in a limited package size can be achieved with this configuration. Our worm equipment features the constant sliding tooth actions between worm and one’s teeth. This escalates the tolerance for weighty loads and shock loads. Worm gear drives offer 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.

A worm equipment reducer is one type of reduction gear container which consists of a worm pinion insight, an output worm equipment, and includes a right angle result orientation. This type of reduction gear container is normally used to take a rated motor quickness and produce a low speed output with higher torque value based on the reduction ratio. They often times can resolve space-saving problems because the worm gear reducer is one of the sleekest decrease gearboxes available due to the little diameter of its output gear.
worm gear reducerWorm equipment reducers are also a popular type of rate 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 utilize a worm equipment reducer. Some of the most typical applications for worm gears can be found in tuning instruments, medical assessment equipment, elevators, security gates, and conveyor belts.
SW-1 and SW-5
Torque Transmission provides two sizes of worm equipment 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 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, noncorrosive, and nonmetallic.
Features
Our worm equipment reducers offer an option of a solid or hollow result shaft and show an adjustable mounting placement. Both the SW-1 and the SW-5, nevertheless, can withstand shock loading much better than other decrease gearbox styles, making them well suited for demanding applications.

Worm Gear Reducers also referred to as worm gearbox or worm quickness reducers. Worm equipment reducers are used for speed reduction and raising the torque for electric powered engine drives. You can decide to attach your NEMA electric motor to the reducer utilizing the NEMA C face flange or use a coupling. If you need a coupling for the result or input shaft find our coupling section for choosing the coupling. We offer four assemblies left hands and right hands and double output shaft and shaft insight and shaft result. Interchangeable with the majority of 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 gear reducers are used in low to moderate horsepower applications to lessen 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, remaining or dual result shafts or a hollow bore output. The indirect drive models are shaft input-shaft result boxes for make use of with sprocket or pulley drive systems. They offer an effective low cost solution to speed reduction and improved 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 mandatory torque and provider factor for the application form. Click on “Specs” above for a desk that will aid in determining the service element. For service factors above 1.0, multiply the required torque by the support factor.
