worm gear speed reducer
One reduction worm gearing offers high ratio reduction with few shifting parts in a close-coupled compact drive. The right angle set up of driving-to-driven machine requires a minimum of space. Input and result shafts can be extended in either or both directions in horizontal or vertical plans adaptable to any mounting requirement. Efficient engine speeds are decreased to sluggish speed requirements of several industrial machines in a single reduction.

The exclusive use of the involute Helicoid Thread form (with departing side contact) on the worm and gear provides for high efficiencies, and long service lifestyle. The hardened ground and polished alloy metal worm develops a simple, 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. Ever-Power offers a broad selection of model configurations, sizes, ratios, and accessories from our standard product line.
Fabricated Designs
If your application involves serious shock loads or feasible housing damage from external sources (as in steel mills or mobile equipment applications) Ever-Power can offer 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 systems. Extra heavy aspect plates connect the worm and gear shaft bearing facilitates, assuring appropriate meshing of the apparatus under all load circumstances. In smaller sizes, fabricated metal reducers are interchangeable with Ever-Power regular cast iron reducers.
Custom Designs
Ever-Power can provide custom quickness and reversed engineered reducers for the application, be it a new project or a direct drop-in alternative to a competitor’s speed reducer. Fabricated metal reducers enable Ever-Power to match a competitor’s footprint, centerline, and shaft height allowing a direct drop-in replacement saving the customer time and money.
Long – Quiet Life
All worm gears in Ever-Power reducers are produced from phosphorous bronze. Our design also includes a hardened, ground and polished alloy metal worm. This combination develops a even, work-hardened mating surface of the bronze equipment which enhances with prolonged service.
Worm gearing is a class of gear reducers that utilizes right angle, nonintersecting shafts. This style of reducer provides soft and quiet procedure and allows for the possibility of large velocity 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 compact design and construction allows worm equipment reducers to be positioned in a comparatively small space. Thus, very high reductions in a limited package size can be achieved with this configuration. Our worm gear features the continuous sliding tooth actions between worm and one’s teeth. This increases the tolerance for weighty loads and shock loads. Worm gear drives provide users high reducing convenience of relatively low cost when compared to some 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 equipment reducer is one type of reduction gear package which consists of a worm pinion input, an output worm equipment, and features a right angle output orientation. This kind of reduction gear package is normally used to have a rated motor acceleration and create 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 one of the sleekest decrease gearboxes available due to the little diameter of its result gear.
worm gear reducerWorm gear reducers are also a favorite type of rate reducer because they offer the greatest speed reduction in the smallest package. With a high ratio of speed reduction and high torque output multiplier, it’s unsurprising that many power transmission systems utilize a worm gear reducer. Some of the most typical applications for worm gears can be found in tuning instruments, medical screening 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 these options are manufactured with rugged compression-molded glass-fill up polyester housings for a durable, long lasting, light weight speed reducer that’s also compact, noncorrosive, and nonmetallic.
Features
Our worm gear reducers offer an option of a solid or hollow result shaft and feature an adjustable mounting placement. Both the SW-1 and the SW-5, however, can withstand shock loading better than other reduction gearbox designs, making them well suited for demanding applications.

Worm Gear Reducers also called worm gearbox or worm acceleration reducers. Worm gear reducers are used for speed decrease and increasing the torque for electric powered motor drives. You can choose to attach your NEMA electric motor to the reducer utilizing the NEMA C face flange or use a coupling. If you need a coupling for the result or input shaft see our coupling section for selecting a coupling. You can expect four assemblies left hand and right hand and double result shaft and shaft insight and shaft result. Interchangeable with many worm gear manufactures.

Ever-Power DDVM series triple-reduction worm gear swiftness reducers can be found in ratios from 5000:1 to 175,000:1 and middle distances from 7” to 20” (larger sizes available on request). Output torque ranges from 33,000 in lbs. for the 7” CD DDVM-70 to 582,900 in pounds for the DDVM-200. Mechanical HP insight 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 installed.
These reducers are perfect for water/waste-water tools drive applications such as for example 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 power panels, astronomical telescopes, indexing tables, hoists, conveyors, or other process or materials handling systems where huge torques/sluggish speeds are needed.

Description
The HDR Series worm equipment reducers are used 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, 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 decrease and increased torque, with higher tolerances for shock loading than helical gear reducers.
In order to select a gearbox speed reducer, you will need to determine the mandatory torque and provider factor for the application. Click on “Specifications” above for a table that will aid in identifying the service aspect. For service factors above 1.0, multiply the mandatory torque by the assistance factor.
