One 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 decreased to slow speed requirements of several industrial machines in one reduction.

The exclusive usage of the involute Helicoid Thread form (with departing side contact) on the worm and gear provides for high efficiencies, and long service existence. The hardened ground and polished alloy steel worm develops a soft, work hardened surface area on the bronze equipment. For this reason worm gears wear in and improve with extented service while additional gears are deteriorating. Ever-Power offers a wide collection of model configurations, sizes, ratios, and add-ons from our standard products.
Fabricated Designs
If your application involves severe shock loads or feasible housing damage from external sources (as in steel mills or mobile apparatus applications) Ever-Power can offer fabricated steel housings with up to a 48″ center distances. Fabricated housings provide maximum rigidity and strength which allows the transmission of higher horsepower levels than are possible with regular cast iron units. Extra heavy part plates connect the worm and gear shaft bearing facilitates, assuring proper meshing of the gear under all load conditions. In smaller sizes, fabricated metal reducers are interchangeable with Ever-Power standard cast iron reducers.
Custom Designs
Ever-Power can offer custom rate and reversed engineered reducers for your application, be it a new project or a primary drop-in replacement for a competitor’s velocity reducer. Fabricated steel reducers enable Ever-Power to match a competitor’s footprint, centerline, and shaft height 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 steel worm. This combination develops a smooth, work-hardened mating surface area of the bronze gear which enhances with prolonged service.
Worm gearing is a class of equipment reducers that utilizes right angle, nonintersecting shafts. This form of reducer provides clean and quiet procedure and permits the likelihood of large speed reductions. These gears are available from stock in a wide selection of ratios, from only 4:1 to as much as 3600:1. The compact design and construction allows worm equipment reducers to be placed in a relatively small space. Thus, high reductions in a limited package size can be achieved with this configuration. Our worm equipment features the continuous sliding tooth actions between worm and one’s teeth. This escalates the tolerance for weighty loads and shock loads. Worm gear drives offer users high reducing capacity for 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 utilize worm gearing are: conveyors, mixers and bucket elevators.

A worm gear reducer is one kind of reduction gear box which includes a worm pinion input, an output worm gear, and includes a right angle output orientation. This kind of reduction gear package is normally used to have a rated motor velocity and create a low speed output with higher torque worth based on the decrease ratio. They often can solve space-saving problems since the worm gear reducer is among the sleekest reduction gearboxes available because of the small diameter of its output gear.
worm gear reducerWorm gear reducers are also a favorite type of speed reducer because they offer the greatest speed reduction in the smallest package. With a higher 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 typical applications for worm gears are available in tuning instruments, medical screening equipment, elevators, protection gates, and conveyor belts.
SW-1 and SW-5
Torque Transmission provides 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 these options are manufactured with durable compression-molded glass-fill polyester housings for a durable, long lasting, light-weight speed reducer that’s also compact, non-corrosive, and nonmetallic.
Features
Our worm equipment reducers offer a choice of a solid 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 ideal for demanding applications.

Worm Equipment Reducers also known as worm gearbox or worm swiftness reducers. Worm equipment reducers are utilized for speed reduction and raising the torque for electric electric motor drives. You can choose to mount your NEMA motor to the reducer by using the NEMA C encounter flange or use a coupling. If you need a coupling for the output or input shaft observe our coupling section for choosing the coupling. You can expect four assemblies left hand and right hand and double result shaft and shaft input and shaft output. Interchangeable with the majority of worm gear manufactures. Observe data sheet in product 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 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 perfect for water/waste-water equipment 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 panels, astronomical telescopes, indexing tables, hoists, conveyors, or other process or components 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, remaining or dual result shafts or a hollow bore result. The indirect drive models are shaft input-shaft output boxes for make use of with sprocket or pulley drive systems. They offer an effective low priced 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 required torque and program factor for the application form. Click on “Specifications” above for a table that will assist in determining the service factor. For service factors above 1.0, multiply the required torque by the provider factor.
