Solitary reduction worm gearing offers high ratio reduction with few shifting parts in a close-coupled small drive. The right angle set up of driving-to-driven machine takes a minimum of space. Input and output shafts can be prolonged in either or both directions in horizontal or vertical plans adaptable to any installation requirement. Efficient engine speeds are decreased to sluggish speed requirements of many 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 lengthy service lifestyle. The hardened surface and polished alloy steel worm develops a smooth, work hardened surface on the bronze equipment. For this reason worm gears wear in and improve with prolonged service while additional gears are deteriorating. Ever-Power offers a broad selection of model configurations, sizes, ratios, and accessories from our standard product line.
Fabricated Designs
If the application involves serious shock loads or possible housing damage from external sources (as in steel mills or mobile gear applications) Ever-Power can offer fabricated steel housings with up to a 48″ center distances. Fabricated housings provide maximum rigidity and strength that allows the transmission of higher horsepower amounts than are possible with standard cast iron units. Extra heavy side plates connect the worm and equipment shaft bearing facilitates, assuring correct meshing of the gear under all load circumstances. In smaller sized sizes, fabricated steel reducers are interchangeable with Ever-Power standard cast iron reducers.
Custom Designs
Ever-Power can provide custom quickness and reversed engineered reducers for your application, be it a fresh project or a primary drop-in replacement for a competitor’s quickness reducer. Fabricated steel reducers allow Ever-Power to complement a competitor’s footprint, centerline, and shaft height allowing a direct 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 includes a hardened, ground and polished alloy steel worm. This mixture develops a smooth, work-hardened mating surface area of the bronze gear which boosts with prolonged service.
Worm gearing is a course of gear reducers that utilizes correct angle, nonintersecting shafts. This style of reducer provides smooth and quiet operation and allows for the probability of large velocity reductions. These gears are available from share in a wide variety of ratios, from only 4:1 up to 3600:1. The compact design and building allows worm gear 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 gear features the continuous sliding tooth actions between worm and one’s teeth. This escalates the tolerance for heavy 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 usage 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 equipment reducer is one kind of reduction gear package which contains a worm pinion insight, an output worm gear, and includes a right angle output orientation. This kind of reduction gear box is generally used to take a rated motor velocity and produce a low speed output with higher torque value based on the decrease ratio. They often can resolve space-saving problems since the worm equipment reducer is among the sleekest reduction gearboxes available due to the little diameter of its result gear.
worm gear reducerWorm equipment reducers are also a popular type of speed 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 lots of power transmission systems utilize a worm gear reducer. Some of the most common applications for worm gears can be found in tuning instruments, medical tests equipment, elevators, security 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 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 of these options are manufactured with durable compression-molded glass-fill up polyester housings for a durable, long lasting, light-weight speed reducer that is also compact, noncorrosive, and nonmetallic.
Features
Our worm equipment reducers offer a choice of a solid or hollow result shaft and show an adjustable mounting position. Both SW-1 and the SW-5, nevertheless, can endure shock loading much better than other reduction gearbox designs, making them perfect for demanding applications.

Worm Equipment Reducers also known as worm gearbox or worm rate reducers. Worm gear reducers are used for speed decrease and raising the torque for electrical engine drives. You can decide to install your NEMA motor to the reducer utilizing the NEMA C face flange or use 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 input and shaft result. Interchangeable with most 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 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 can be found in four configurations: horizontal, vertical, shafted, and shaft installed.
These reducers are well suited for water/waste-water equipment drive applications such as thickeners and clarifiers, which require a vertical down shaft. Other obtainable configurations also make Ever-Power triple decrease reducers perfect for use on mixers, elevators, solar power panels, astronomical telescopes, indexing tables, hoists, conveyors, or various other process or materials handling systems where large torques/slower speeds are needed.
These reducers are also offered with a helical major reduction stage and are termed the HDVM series

Description
The HDR Series worm equipment reducers are used 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, left or dual output shafts or a hollow bore result. The indirect drive models are shaft input-shaft output boxes for use with sprocket or pulley drive systems. They provide an effective low priced 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 have to determine the mandatory torque and support factor for the application. Click on “Specifications” above for a table that will assist in identifying the service factor. For service elements above 1.0, multiply the required torque by the service factor.
