worm gear speed reducer

Single reduction worm gearing offers high ratio reduction with few shifting parts in a close-coupled compact drive. The proper angle set up of driving-to-driven machine takes a the least space. Input and output shafts can be extended in either or both directions in horizontal or vertical plans adaptable to any installation requirement. Efficient electric motor speeds are reduced to gradual speed requirements of several industrial machines in a single reduction.

The exclusive usage of the involute Helicoid Thread form (with leaving side contact) on the worm and gear offers high efficiencies, and lengthy service existence. The hardened floor and polished alloy steel worm develops a soft, work hardened surface on the bronze gear. For this reason worm gears use in and improve with prolonged service while other gears are wearing out. EP offers a wide selection of model configurations, sizes, ratios, and accessories from our standard products.
Fabricated Designs
If your application involves serious shock loads or feasible housing damage from external sources (as in steel mills or mobile tools 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 amounts than are possible with standard cast iron models. Extra heavy aspect plates connect the worm and equipment shaft bearing facilitates, assuring proper meshing of the gear under all load conditions. In smaller sizes, fabricated steel reducers are interchangeable with EP standard cast iron reducers.
Custom Designs
EP can offer custom acceleration and reversed engineered reducers for your application, be it a new project or a primary drop-in alternative to a competitor’s speed reducer. Fabricated steel reducers enable EP to match a competitor’s footprint, centerline, and shaft height allowing a direct drop-in replacement saving the client time and money.
Long – Quiet Life
All worm gears in EP reducers are produced from phosphorous bronze. Our design also incorporates a hardened, floor and polished alloy steel worm. This mixture develops a smooth, work-hardened mating surface area of the bronze equipment which enhances with prolonged service.
Worm gearing is a class of equipment reducers that utilizes correct angle, nonintersecting shafts. This form of reducer provides simple and quiet procedure and permits the probability of large rate reductions. These gears can be found from stock in a wide variety of ratios, from as low as 4:1 up to 3600:1. The small design and structure allows worm equipment reducers to be placed in a relatively small space. Thus, very high reductions in a restricted package size may be accomplished with this configuration. Our worm equipment features the continuous sliding tooth actions between worm and one’s teeth. This escalates the tolerance for heavy loads and shock loads. Worm gear drives provide users high reducing convenience of relatively low cost in comparison with 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 input, an output worm gear, and includes a right angle output orientation. This type of reduction gear package is generally used to have a rated motor speed and produce a low speed output with higher torque value based on the decrease ratio. They often times can resolve space-saving problems because the worm equipment reducer is among the sleekest decrease gearboxes available due to the small diameter of its result gear.
worm gear reducerWorm gear reducers are also a favorite type of acceleration reducer because they offer the greatest speed decrease in the tiniest package. With a high ratio of speed decrease and high torque result multiplier, it’s unsurprising that many power transmission systems make use of a worm equipment reducer. Some of the most common 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 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 produced with tough compression-molded glass-fill polyester housings for a long lasting, long lasting, light weight speed reducer that’s also compact, non-corrosive, and nonmetallic.
Features
Our worm gear reducers offer an option of a solid or hollow output shaft and feature an adjustable mounting position. Both SW-1 and the SW-5, nevertheless, can withstand shock loading better than other reduction gearbox styles, making them ideal for demanding applications.

Worm Equipment Reducers also known as worm gearbox or worm velocity reducers. Worm equipment reducers are utilized for speed decrease and increasing the torque for electric motor drives. You can choose to mount your NEMA electric motor 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 selecting a coupling. We offer four assemblies left hands and right hand and double output shaft and shaft insight and shaft result. Interchangeable with most 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 found in low to moderate horsepower applications to lessen speeds and increase torque. Worm gear reducers are available in direct or indirect drive, direct drive models are 56C or 145TC flange attach with either right, remaining or dual output shafts or a hollow bore output. The indirect drive models are shaft input-shaft result boxes for use 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 gear reducers.
In order to decide on a gearbox speed reducer, you will need to determine the mandatory torque and assistance factor for the application form. Click on “Specs” above for a desk that will aid in determining the service element. For service elements above 1.0, multiply the required torque by the services factor.
Our standard 700 Series – the heart of EP quickness reducer products – has been serving industry reliably for over 40 years. Its tested modular design has set the market standard for performance and may be the most imitated item in the current worm gear speed reducer marketplace. But why accept a knock-off when you’re able to have the original – from EP.
