worm gear speed reducer

One reduction worm gearing offers high ratio reduction with couple of shifting parts in a close-coupled compact drive. The right angle set up of driving-to-driven machine takes a minimum of space. Input and output shafts can be prolonged in either or both directions in horizontal or worm gear speed reducer vertical arrangements 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 usage of the involute Helicoid Thread form (with departing side contact) on the worm and gear provides for high efficiencies, and lengthy service life. The hardened surface and polished alloy steel worm develops a easy, work hardened surface on the bronze gear. Because of this worm gears wear in and improve with prolonged service while other gears are wearing out. Ever-Power offers a broad collection of model configurations, sizes, ratios, and accessories from our standard product line.
Fabricated Designs
If the application involves severe shock loads or possible housing damage from external sources (as in steel mills or mobile tools applications) Ever-Power 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 levels than are feasible with regular cast iron units. Extra heavy side plates connect the worm and equipment shaft bearing facilitates, assuring proper meshing of the apparatus under all load circumstances. In smaller sized sizes, fabricated steel reducers are interchangeable with Ever-Power regular cast iron reducers.
Custom Designs
Ever-Power can provide custom rate and reversed engineered reducers for your application, be it a fresh project or a direct drop-in replacement for a competitor’s quickness reducer. Fabricated steel reducers allow Ever-Power to match a competitor’s footprint, centerline, and shaft height allowing a primary drop-in substitute saving the customer time and money.
Long – Quiet Life
All worm gears in Ever-Power reducers are manufactured from phosphorous bronze. Our style also incorporates a hardened, floor and polished alloy steel worm. This mixture develops a smooth, work-hardened mating surface of the bronze gear which increases with prolonged service.
Worm gearing is a course of gear reducers that utilizes right angle, nonintersecting shafts. This form of reducer provides easy and quiet operation and permits the probability of large swiftness reductions. These gears are available from stock in a wide selection of ratios, from only 4:1 up to 3600:1. The compact design and structure allows worm gear reducers to be positioned 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 action between worm and the teeth. This increases the tolerance for weighty loads and shock loads. Worm gear drives offer users high reducing convenience of relatively low cost when compared to 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 make use of worm gearing are: conveyors, mixers and bucket elevators.

A worm gear reducer is one type of reduction gear container which consists of a worm pinion input, an output worm gear, and includes a right angle output orientation. This type of reduction gear box is normally used to take a rated motor quickness and produce a low speed result with higher torque worth based on the decrease ratio. They often can solve space-saving problems because the worm equipment reducer is among the sleekest reduction gearboxes available due to the small diameter of its result gear.
worm gear reducerWorm gear reducers are also a popular type of swiftness reducer because they offer the greatest speed reduction in the tiniest package. With a high ratio of speed decrease and high torque result multiplier, it’s unsurprising that lots of power transmission systems utilize a worm gear reducer. Some of the most common applications for worm gears can be found in tuning instruments, medical examining 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 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 rugged compression-molded glass-fill polyester housings for a long lasting, long lasting, light weight speed reducer that is also compact, noncorrosive, and nonmetallic.
Features
Our worm gear reducers offer a choice of a good or hollow result shaft and feature 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 ideal for demanding applications.

Worm Gear Reducers also referred to as worm gearbox or worm rate reducers. Worm equipment reducers are utilized for speed decrease and raising the torque for electric engine drives. You can choose to install your NEMA electric motor to the reducer by using the NEMA C face flange or make use of a coupling. If you need a coupling for the result or input shaft see our coupling section for choosing the coupling. We offer four assemblies left hand and right hand and double result shaft and shaft input and shaft output. Interchangeable with most worm gear manufactures. See data sheet in item overview for diamensions. Unless you see your type, make sure you Contact Us.

Ever-Power DDVM series triple-reduction worm gear velocity 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 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 ideal for water/waste-water devices drive applications such as for example thickeners and clarifiers, which require a vertical straight down shaft. Other offered configurations also make Ever-Power triple reduction reducers perfect for use on mixers, elevators, solar power panels, astronomical telescopes, indexing tables, hoists, conveyors, or various other process or materials handling systems where large torques/gradual speeds are needed.
These reducers are also available with a helical main reduction stage and so are termed the HDVM series

Description
The HDR Series worm equipment 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 mount with either right, left or dual output shafts or a hollow bore output. The indirect drive versions are shaft input-shaft output boxes for use with sprocket or pulley drive systems. They provide an effective low cost solution to speed decrease and improved 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 required torque and services factor for the application form. Click on “Specs” above for a table that will aid in identifying the service aspect. For service factors above 1.0, multiply the mandatory torque by the provider factor.
Our standard 700 Series – the heart of Ever-Power velocity reducer products – has been serving industry reliably for over 40 years. Its tested modular design has set the sector standard for functionality and may be the most imitated product in the current worm gear rate reducer market. But why settle for a knock-off when you’re able to have the original – from Ever-Power.
