Solitary reduction worm gearing offers 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 motor speeds are reduced to gradual speed requirements of several industrial machines in one reduction.

The exclusive use of the involute Helicoid Thread form (with leaving side contact) on the worm and gear offers high efficiencies, and lengthy service lifestyle. The hardened surface and polished alloy steel worm develops a clean, work hardened surface area on the bronze equipment. Because of this worm gears use in and improve with prolonged service while additional gears are wearing out. Ever-Power offers a wide collection of model configurations, sizes, ratios, and components from our standard product line.
Fabricated Designs
If your application involves severe shock loads or possible housing damage from external sources (as in steel mills or mobile gear applications) Ever-Power can provide fabricated steel housings with up to a 48″ center distances. Fabricated housings provide optimum rigidity and strength which allows the tranny of higher horsepower amounts than are feasible with standard cast iron models. Extra heavy side plates connect the worm and gear shaft bearing facilitates, assuring correct meshing of the apparatus under all load conditions. In smaller sizes, fabricated steel reducers are interchangeable with Ever-Power regular cast iron reducers.
Custom Designs
Ever-Power can provide custom velocity and reversed engineered reducers for your application, be it a fresh project or a direct drop-in replacement for a competitor’s speed reducer. Fabricated metal 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 includes a hardened, ground and polished alloy steel worm. This combination develops a soft, work-hardened mating surface of the bronze equipment which enhances with prolonged service.
Worm gearing is a course of equipment reducers that utilizes correct angle, nonintersecting shafts. This form of reducer provides smooth 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 to as much as 3600:1. The small design and structure allows worm equipment reducers to be positioned in a relatively small space. Thus, 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 escalates the tolerance for heavy loads and shock loads. Worm gear drives offer users high reducing capacity for relatively low cost in comparison with various other types of gearing.
The utilization 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 kind of reduction gear package which includes a worm pinion input, an output worm equipment, and includes a right angle result orientation. This kind of reduction gear container is normally used to have a rated motor speed and produce a low speed result with higher torque worth based on the decrease ratio. They often can resolve space-saving problems because the worm equipment reducer is one of the sleekest decrease gearboxes available because of the small diameter of its output gear.
worm gear reducerWorm gear reducers are also a favorite type of acceleration reducer because they provide the greatest speed decrease 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 typical applications for worm gears are available in tuning instruments, medical assessment 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 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 these options are produced with tough compression-molded glass-fill up polyester housings for a long lasting, long lasting, light-weight speed reducer that is also compact, noncorrosive, and nonmetallic.
Features
Our worm equipment reducers offer an option of a solid or hollow result shaft and feature an adjustable mounting position. Both SW-1 and the SW-5, however, can endure shock loading better than other decrease gearbox styles, making them well suited for demanding applications.

Worm Equipment Reducers also referred to as worm gearbox or worm velocity reducers. Worm equipment reducers are used for speed reduction and increasing the torque for electrical electric motor drives. You can decide 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 find our coupling section for selecting a coupling. We offer four assemblies left hands and right hand and double output shaft and shaft insight and shaft result. Interchangeable with many 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 quickness reducers can be found in ratios from 5000:1 to 175,000:1 and center distances from 7” to 20” (larger sizes on request). Output torque ranges from 33,000 in lbs. for the 7” CD DDVM-70 to 582,900 in lbs 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 are available 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 straight 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 various other process or components handling systems where huge torques/gradual 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 versions are 56C or 145TC flange mount with either right, remaining or dual result 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 improved 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 required torque and support factor for the application. Click on “Specs” above for a table that will aid in determining the service element. For service elements above 1.0, multiply the mandatory torque by the support factor.
Our standard 700 Series – the heart of Ever-Power velocity reducer product line – has been serving industry reliably for over 40 years. Its verified modular style has set the sector standard for overall performance and is the most imitated product in the current worm gear speed reducer market. But why settle for a knock-off when you’re able to have the original – from Ever-Power.
