One 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 minimum of space. Input and output shafts can be extended in either or both directions in horizontal or vertical plans adaptable to any mounting requirement. Efficient motor speeds are reduced to sluggish speed requirements of many industrial machines in one reduction.

The exclusive usage of the involute Helicoid Thread form (with departing side contact) on the worm and gear offers high efficiencies, and long service lifestyle. The hardened floor and polished alloy steel worm develops a soft, work hardened surface area on the bronze equipment. Because of this worm gears wear in and improve with extented service while additional gears are deteriorating. Ever-Power offers a wide selection of model configurations, sizes, ratios, and accessories from our standard product line.
Fabricated Designs
If your application involves severe shock loads or feasible 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 transmission of higher horsepower amounts than are feasible with standard cast iron units. Extra heavy side plates connect the worm and gear shaft bearing facilitates, assuring proper meshing of the gear 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 acceleration and reversed engineered reducers for the application, be it a new project or a direct drop-in alternative to a competitor’s acceleration reducer. Fabricated metal reducers enable Ever-Power to complement a competitor’s footprint, centerline, and shaft elevation allowing a primary drop-in alternative saving the client time and money.
Long – Quiet Life
All worm gears in Ever-Power reducers are manufactured from phosphorous bronze. Our design also incorporates a hardened, surface and polished alloy metal worm. This mixture develops a soft, work-hardened mating surface of the bronze gear which enhances with prolonged service.
Worm gearing is a course of equipment reducers that utilizes correct angle, nonintersecting shafts. This style of reducer provides soft and quiet procedure and permits the possibility of large acceleration reductions. These gears can be found from share in a wide variety of ratios, from only 4:1 to as much as 3600:1. The compact design and structure allows worm gear reducers to be positioned in a relatively small space. Thus, high reductions in a limited package size may be accomplished with this configuration. Our worm equipment features the constant sliding tooth action between worm and one’s teeth. This increases the tolerance for large 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 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 equipment reducer is one kind of reduction gear container which consists of a worm pinion input, an output worm equipment, and features a right angle result orientation. This kind of reduction gear box is normally used to have a rated motor rate and create a low speed output with higher torque value based on the reduction ratio. They often times can solve space-saving problems since the worm equipment reducer is one of 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 quickness reducer because they offer the greatest speed decrease in the smallest package. With a higher ratio of speed reduction and high torque output multiplier, it’s unsurprising that many power transmission systems make use of a worm gear reducer. Some of the most common applications for worm gears can be found in tuning instruments, medical assessment equipment, elevators, protection gates, and conveyor belts.
SW-1 and SW-5
Torque Transmission offers two sizes of worm gear 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 of these options are produced with durable 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 equipment reducers offer an option of a solid or hollow output shaft and feature an adjustable mounting position. Both SW-1 and the SW-5, however, can withstand shock loading better than other reduction gearbox styles, making them ideal for demanding applications.

Worm Gear Reducers also called worm gearbox or worm speed reducers. Worm equipment reducers are utilized for speed reduction and increasing the torque for electrical motor drives. You can choose to mount your NEMA engine to the reducer by using the NEMA C face flange or make use of a coupling. If you want a coupling for the output or input shaft discover our coupling section for choosing the coupling. We offer four assemblies left hands and right hand and double result shaft and shaft input and shaft output. Interchangeable with most worm gear manufactures. See data sheet in product overview for diamensions. If you don’t see your type, please Contact Us.

Ever-Power DDVM series triple-reduction worm gear quickness reducers are available in ratios from 5000:1 to 175,000:1 and center 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 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 installed.
These reducers are perfect for water/waste-water tools drive applications such as for example thickeners and clarifiers, which require a vertical straight down shaft. Other obtainable configurations also make Ever-Power triple reduction reducers perfect for use on mixers, elevators, solar panels, astronomical telescopes, indexing tables, hoists, conveyors, or additional process or materials handling systems where large torques/slow speeds are needed.
These reducers are also offered with a helical main reduction stage and are termed the HDVM series

Description
The HDR Series worm equipment reducers are found 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 versions are 56C or 145TC flange attach with either right, remaining or dual result shafts or a hollow bore result. The indirect drive versions 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 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 required torque and program factor for the application form. 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 service factor.
