worm gear speed reducer

worm gear speed reducer
Single reduction worm gearing offers high ratio reduction with few shifting parts in a close-coupled compact drive. The right angle arrangement of driving-to-driven machine requires a the least space. Input and result shafts can be extended in either or both directions in horizontal or vertical arrangements adaptable to any installation requirement. Efficient motor speeds are reduced to slower speed requirements of many 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 lengthy service lifestyle. The hardened ground and polished alloy metal worm develops a simple, work hardened surface on the bronze equipment. Because of this worm gears use in and improve with prolonged service while various other gears are wearing out. Ever-Power offers a wide selection of model configurations, sizes, ratios, and components from our standard product line.
Fabricated Designs
If your application involves serious shock loads or possible housing damage from external sources (as in steel mills or mobile products applications) Ever-Power can provide fabricated steel housings with up to 48″ center distances. Fabricated housings provide optimum rigidity and strength that allows the transmission of higher horsepower levels than are feasible with standard cast iron products. Extra heavy side plates connect the worm and equipment shaft bearing supports, assuring proper meshing of the gear under all load circumstances. In smaller sized sizes, fabricated steel reducers are interchangeable with Ever-Power standard cast iron reducers.
Custom Designs
Ever-Power can offer custom velocity and reversed engineered reducers for your application, be it a fresh project or a primary drop-in alternative to a competitor’s speed reducer. Fabricated steel reducers allow Ever-Power to complement a competitor’s footprint, centerline, and shaft elevation allowing a direct drop-in substitute saving the customer time and money.
Long – Quiet Life
All worm gears in Ever-Power reducers are produced from phosphorous bronze. Our design also incorporates a hardened, surface and polished alloy metal worm. This mixture develops a clean, work-hardened mating surface of the bronze gear which improves with prolonged service.
Worm gearing is a class of gear reducers that utilizes correct angle, nonintersecting shafts. This style of reducer provides soft and quiet operation and permits the possibility of large velocity reductions. These gears are available from stock in a wide selection of ratios, from as low as 4:1 up to 3600:1. The compact design and building allows worm gear reducers to be positioned in a relatively small space. Thus, very high reductions in a limited package size may be accomplished with this configuration. Our worm gear features the continuous sliding tooth action between worm and one’s teeth. This increases the tolerance for large loads and shock loads. Worm gear drives provide users high reducing capacity for 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 kind of reduction gear box which contains a worm pinion insight, an output worm gear, and includes a right angle result orientation. This kind of reduction gear package is generally used to take a rated motor rate and create a low speed output with higher torque value based on the reduction ratio. They often times can resolve space-saving problems because the worm equipment reducer is one of the sleekest reduction gearboxes available because of the small diameter of its output gear.
worm gear reducerWorm equipment reducers are also a popular type of acceleration reducer because they provide the greatest speed decrease in the smallest package. With a higher ratio of speed reduction and high torque output multiplier, it’s unsurprising that lots of 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 tests 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 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 tough compression-molded glass-fill polyester housings for a long lasting, long lasting, light weight speed reducer that’s also compact, noncorrosive, and nonmetallic.
Features
Our worm gear reducers offer an option of a good or hollow output shaft and show an adjustable mounting position. Both SW-1 and the SW-5, however, can endure shock loading better than other decrease gearbox designs, making them ideal for demanding applications.

Worm Equipment Reducers also referred to as worm gearbox or worm quickness reducers. Worm equipment reducers are utilized for speed reduction and raising the torque for electric powered motor drives. You can decide to attach your NEMA electric motor to the reducer utilizing the NEMA C encounter flange or make use of a coupling. If you need a coupling for the result or input shaft observe our coupling section for selecting a coupling. You can expect four assemblies left hands and right hand and double result shaft and shaft insight and shaft output. Interchangeable with most worm gear manufactures.

Ever-Power DDVM series triple-reduction worm gear quickness reducers are available in ratios from 5000:1 to 175,000:1 and middle distances from 7” to 20” (larger sizes available on request). Result torque ranges from 33,000 in pounds. for the 7” CD DDVM-70 to 582,900 in pounds 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 equipment drive applications such as thickeners and clarifiers, which require a vertical down shaft. Other offered configurations also make Ever-Power triple reduction reducers perfect for use on mixers, elevators, solar panels, astronomical telescopes, indexing tables, hoists, conveyors, or additional process or components handling systems where huge torques/sluggish speeds are needed.

Description
The HDR Series worm gear reducers are found 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 result. The indirect drive versions are shaft input-shaft result boxes for use with sprocket or pulley drive systems. They offer an effective low cost solution to speed reduction and increased torque, with higher tolerances for shock loading than helical equipment reducers.
In order to select a gearbox speed reducer, you will need to determine the mandatory torque and service factor for the application. Click on “Specs” above for a desk that will aid in identifying the service factor. For service factors above 1.0, multiply the mandatory torque by the support factor.
