worm gear speed reducer

Solitary reduction worm gearing offers high ratio reduction with couple of 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 motor speeds are decreased to slow speed requirements of several industrial machines in one reduction.

The exclusive utilization of the involute Helicoid Thread form (with leaving side contact) on the worm and gear provides for high efficiencies, and lengthy service existence. The hardened ground and polished alloy metal worm develops a even, work hardened surface on the bronze gear. For this reason worm gears put on in and improve with extented service while other gears are wearing out. EP offers a wide collection 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 gear applications) EP can provide fabricated steel housings with up to a 48″ center distances. Fabricated housings provide optimum rigidity and strength that allows the transmitting of higher horsepower amounts than are feasible with regular cast iron devices. Extra heavy part plates connect the worm and gear shaft bearing facilitates, assuring appropriate meshing of the apparatus under all load circumstances. In smaller sized sizes, fabricated metal reducers are interchangeable with EP standard cast iron reducers.
Custom Designs
EP can offer custom velocity and reversed engineered reducers for the application, be it a fresh project or a primary drop-in replacement for a competitor’s quickness reducer. Fabricated metal reducers enable EP to match a competitor’s footprint, centerline, and shaft elevation allowing a primary drop-in alternative saving the customer time and money.
Long – Quiet Life
All worm gears in EP reducers are produced from phosphorous bronze. Our design also includes a hardened, surface and polished alloy steel worm. This mixture develops a clean, work-hardened mating surface area of the bronze gear which increases with prolonged service.
Worm gearing is a course of equipment reducers that utilizes right angle, nonintersecting shafts. This form of reducer provides clean and quiet procedure and allows for the probability 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 small design and structure allows worm equipment reducers to be placed in a relatively small space. Thus, high reductions in a limited package size may be accomplished with this configuration. Our worm gear features the continuous sliding tooth actions between worm and the teeth. This increases the tolerance for heavy loads and shock loads. Worm gear drives offer users high reducing convenience of relatively low cost in comparison with 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 make use of worm gearing are: conveyors, mixers and bucket elevators.

A worm equipment reducer is one kind of reduction gear box which contains a worm pinion input, an output worm equipment, and includes a right angle output orientation. This kind of reduction gear box is normally used to take a rated motor velocity and create a low speed output with higher torque worth based on the reduction ratio. They often can resolve space-saving problems since the worm gear reducer is among the sleekest reduction gearboxes available because of the small diameter of its result gear.
worm gear reducerWorm equipment reducers are also a favorite type of speed reducer because they provide the greatest speed decrease in the tiniest package. With a higher ratio of speed reduction and high torque output multiplier, it’s unsurprising that many power transmission systems make use of a worm gear reducer. Some of the most typical applications for worm gears can be found in tuning instruments, medical testing 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 of these options are manufactured with tough compression-molded glass-fill polyester housings for a long lasting, long lasting, light-weight speed reducer that is also compact, non-corrosive, 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, nevertheless, can endure shock loading better than other decrease gearbox styles, making them perfect for demanding applications.

Worm Equipment Reducers also known as worm gearbox or worm swiftness reducers. Worm gear reducers are used for speed reduction and raising the torque for electrical electric motor drives. You can choose to attach your NEMA electric motor to the reducer utilizing the NEMA C encounter flange or use a coupling. If you want a coupling for the result or input shaft discover our coupling section for choosing the coupling. We offer four assemblies left hand and right hands and double result shaft and shaft input and shaft result. Interchangeable with many worm gear manufactures.

EP DDVM series triple-reduction worm gear rate reducers can be found in ratios from 5000:1 to 175,000:1 and center distances from 7” to 20” (larger sizes available on request). Result torque ranges from 33,000 in lbs. for the 7” CD DDVM-70 to 582,900 in lbs for the DDVM-200. Mechanical HP input requirements are from 0.09 HP for the 175,000:1 7 in CD reducer to 6.25 HP for the 5000:1 20” CD unit. These reducers can be found in four configurations: horizontal, vertical, shafted, and shaft mounted.
These reducers are well suited for water/waste-water apparatus drive applications such as for example thickeners and clarifiers, which require a vertical straight down shaft. Other obtainable configurations also make EP triple reduction reducers perfect for make use of on mixers, elevators, solar power panels, astronomical telescopes, indexing tables, hoists, conveyors, or additional process or components handling systems where large torques/sluggish speeds are needed.

Description
The HDR Series worm gear reducers are used in low to moderate horsepower applications to lessen speeds and increase torque. Worm gear reducers can be found in direct or indirect drive, direct drive models are 56C or 145TC flange install with either right, still left or dual output 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 provide an effective low cost solution to speed reduction and improved 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 provider factor for the application. Click on “Specs” above for a table that will aid in identifying the service aspect. For service elements above 1.0, multiply the mandatory torque by the assistance factor.
