worm gear speed reducer

Solitary reduction worm gearing provides high ratio reduction with couple of shifting parts in a close-coupled compact drive. The right angle arrangement of driving-to-driven machine takes 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 electric motor speeds are decreased to sluggish speed requirements of several industrial machines in one reduction.

The exclusive usage of the involute Helicoid Thread form (with leaving side contact) on the worm and gear offers high efficiencies, and long service lifestyle. The hardened ground and polished alloy metal worm develops a smooth, work hardened surface area on the bronze equipment. Because of this worm gears use in and improve with extented service while other gears are deteriorating. EP offers a broad selection of model configurations, sizes, ratios, and accessories 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 equipment applications) EP can provide 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 standard cast iron devices. Extra heavy side plates connect the worm and equipment shaft bearing facilitates, assuring correct meshing of the apparatus under all load circumstances. In smaller sized sizes, fabricated metal reducers are interchangeable with EP regular cast iron reducers.
Custom Designs
EP can provide custom acceleration and reversed engineered reducers for the application, be it a fresh project or a primary drop-in alternative to a competitor’s acceleration reducer. Fabricated steel reducers enable EP to match a competitor’s footprint, centerline, and shaft height 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 style also includes a hardened, ground and polished alloy metal worm. This mixture develops a soft, work-hardened mating surface area of the bronze gear which enhances with prolonged service.
Worm gearing is a class of gear reducers that utilizes right angle, nonintersecting shafts. This style of reducer provides clean and quiet procedure and allows for the likelihood of large swiftness reductions. These gears can be found from stock in a wide selection of ratios, from as low as 4:1 to as much as 3600:1. The compact design and building allows worm gear 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 equipment features the constant 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 use 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 equipment reducer is one type of reduction gear package which consists of a worm pinion input, an output worm equipment, and includes a right angle output orientation. This kind of reduction gear container is generally used to have a rated motor speed and create a low speed result with higher torque value based on the reduction ratio. They often can resolve space-saving problems because 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 velocity reducer because they provide the greatest speed decrease in the tiniest package. With a high ratio of speed decrease and high torque output 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 tests equipment, elevators, security gates, and conveyor belts.
SW-1 and SW-5
Torque Transmission offers two sizes of worm gear 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 rugged compression-molded glass-fill up 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 an option of a good or hollow output shaft and show an adjustable mounting placement. Both the SW-1 and the SW-5, however, can endure shock loading better than other reduction gearbox styles, making them well suited for demanding applications.

Worm Gear Reducers also referred to as worm gearbox or worm rate reducers. Worm equipment reducers are utilized for speed reduction and increasing the torque for electrical motor drives. You can choose to install your NEMA motor to the reducer by using the NEMA C face flange or make use of a coupling. If you want a coupling for the output or input shaft observe our coupling section for choosing the coupling. You can expect four assemblies left hands and right hands and double output shaft and shaft insight and shaft result. Interchangeable with many worm gear manufactures.

EP DDVM series triple-reduction worm gear quickness reducers can be found in ratios from 5000:1 to 175,000:1 and middle distances from 7” to 20” (larger sizes on request). Result torque ranges from 33,000 in pounds. 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 are available in four configurations: horizontal, vertical, shafted, and shaft mounted.
These reducers are ideal for water/waste-water gear drive applications such as for example thickeners and clarifiers, which need a vertical straight down shaft. Other obtainable configurations also make EP triple reduction reducers perfect for use on mixers, elevators, solar panels, astronomical telescopes, indexing tables, hoists, conveyors, or various other process or components handling systems where huge torques/gradual speeds are needed.
These reducers are also obtainable with a helical major reduction stage and so are termed the HDVM series

Description
The HDR Series worm gear 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 attach with either right, left or dual result shafts or a hollow bore result. The indirect drive versions are shaft input-shaft result boxes for make use of with sprocket or pulley drive systems. They provide an effective low priced solution to speed decrease and increased torque, with higher tolerances for shock loading than helical gear reducers.
In order to select a gearbox speed reducer, you will have to determine the mandatory torque and provider factor for the application. Click on “Specs” above for a desk that will aid in determining the service factor. For service elements above 1.0, multiply the mandatory torque by the support factor.
