Single reduction worm gearing offers high ratio reduction with couple of shifting parts in a close-coupled small drive. The right angle set up of driving-to-driven machine requires a minimum of space. Input and result shafts can be prolonged in either or both directions in horizontal or vertical plans adaptable to any installation requirement. Efficient electric motor speeds are reduced to slower speed requirements of several industrial machines in a single reduction.

The exclusive utilization of the involute Helicoid Thread form (with departing side contact) on the worm and gear provides for high efficiencies, and long service life. The hardened floor and polished alloy metal worm develops a smooth, work hardened surface on the bronze gear. For this reason worm gears use in and improve with extented service while additional gears are wearing out. Ever-Power offers a wide selection of model configurations, sizes, ratios, and add-ons from our standard products.
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 that allows the transmission of higher horsepower amounts than are feasible with regular cast iron units. Extra heavy side plates connect the worm and gear shaft bearing supports, assuring appropriate meshing of the apparatus under all load circumstances. In smaller sizes, fabricated steel reducers are interchangeable with Ever-Power standard cast iron reducers.
Custom Designs
Ever-Power can offer custom speed and reversed engineered reducers for your application, be it a new project or a direct drop-in replacement for a competitor’s velocity reducer. Fabricated metal reducers enable Ever-Power to match a competitor’s footprint, centerline, and shaft height allowing a primary drop-in replacement saving the client 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 combination develops a smooth, work-hardened mating surface of the bronze gear which boosts with prolonged service.
Worm gearing is a class of equipment reducers that utilizes correct angle, nonintersecting shafts. This form of reducer provides simple and quiet operation and allows for the probability of large acceleration reductions. These gears can be found from stock in a wide variety of ratios, from only 4:1 up to 3600:1. The compact design and building 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 action between worm and the teeth. This increases the tolerance for weighty loads and shock loads. Worm gear drives offer users high reducing capacity for 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 utilize worm gearing are: conveyors, mixers and bucket elevators.

A worm gear reducer is one type of reduction gear package which worm gear speed reducer 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 quickness and produce a low speed output with higher torque value based on the decrease ratio. They often times can solve space-saving problems since the worm gear reducer is among the sleekest reduction gearboxes available because of the little diameter of its output gear.
worm gear reducerWorm gear reducers are also a popular type of swiftness reducer because they provide the greatest speed decrease in the tiniest package. With a higher 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 common applications for worm gears are available in tuning instruments, medical tests equipment, elevators, protection 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 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 durable compression-molded glass-fill up polyester housings for a long lasting, 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 position. Both the SW-1 and the SW-5, nevertheless, can withstand shock loading much better than other reduction gearbox designs, making them well suited for demanding applications.

Worm Equipment Reducers also referred to as worm gearbox or worm swiftness reducers. Worm gear reducers are utilized for speed reduction and increasing the torque for electric engine drives. You can choose to install your NEMA motor to the reducer by using the NEMA C face flange or make use of a coupling. If you need a coupling for the output or input shaft observe our coupling section for choosing the coupling. We offer four assemblies left hand and right hand and double output shaft and shaft insight and shaft result. Interchangeable with many worm gear manufactures.

Ever-Power DDVM series triple-reduction worm gear quickness 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 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 can be found in four configurations: horizontal, vertical, shafted, and shaft mounted.
These reducers are well suited for water/waste-water apparatus drive applications such as thickeners and clarifiers, which require a vertical straight down shaft. Other offered configurations also make Ever-Power triple decrease reducers perfect for use on mixers, elevators, solar power panels, astronomical telescopes, indexing tables, hoists, conveyors, or additional process or materials handling systems where huge torques/slower speeds are needed.
These reducers are also offered with a helical major 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 reduce speeds and increase torque. Worm gear reducers are available in direct or indirect drive, direct drive models are 56C or 145TC flange install with either right, 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 reduction and increased 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 support factor for the application. Click on “Specs” above for a table that will aid in identifying the service factor. For service elements above 1.0, multiply the mandatory torque by the provider factor.
