worm gear speed reducer
Solitary reduction worm gearing provides 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 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 electric 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 provides for high efficiencies, and long service lifestyle. The hardened floor and polished alloy steel worm develops a soft, work hardened surface area on the bronze gear. For this reason worm gears wear in and improve with prolonged service while additional gears are wearing out. Ever-Power offers a wide selection of model configurations, sizes, ratios, and add-ons from our standard product line.
Fabricated Designs
If the application involves severe shock loads or feasible housing damage from external sources (as in steel mills or mobile apparatus 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 transmitting of higher horsepower amounts than are feasible with regular cast iron devices. Extra heavy part plates connect the worm and equipment shaft bearing supports, assuring appropriate meshing of the gear under all load circumstances. In smaller sized sizes, fabricated metal reducers are interchangeable with Ever-Power regular cast iron reducers.
Custom Designs
Ever-Power can provide custom rate and reversed engineered reducers for your application, be it a fresh project or a primary drop-in alternative to a competitor’s speed reducer. Fabricated metal reducers enable Ever-Power to complement a competitor’s footprint, centerline, and shaft height allowing a primary drop-in substitute 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, ground and polished alloy metal worm. This combination develops a simple, work-hardened mating surface of the bronze equipment which improves with prolonged service.
Worm gearing is a course of equipment reducers that utilizes correct angle, nonintersecting shafts. This style of reducer provides even and quiet operation and permits the possibility 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 positioned in a relatively small space. Thus, very high reductions in a restricted package size can be achieved with this configuration. Our worm gear features the constant sliding tooth action between worm and one’s teeth. This increases 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 usage of worm gearing extends across many industries including food, beverage and grain and has many applications. Some applications that use worm gearing are: conveyors, mixers and bucket elevators.

A worm gear reducer is one type of reduction gear package which consists of a worm pinion input, an output worm gear, and includes a right angle result orientation. This type of reduction gear container is generally used to have a rated motor rate and produce a low speed output with higher torque value based on the reduction ratio. They often can solve space-saving problems since the worm equipment reducer is one of the sleekest reduction gearboxes available due to the little diameter of its output gear.
worm gear reducerWorm equipment reducers are also a favorite type of acceleration reducer because they offer the greatest speed reduction in the tiniest package. With a higher ratio of speed decrease 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 are available in tuning instruments, medical testing equipment, elevators, security gates, and conveyor belts.
SW-1 and SW-5
Torque Transmission provides two sizes of worm gear 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 of these options are manufactured with rugged 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 gear reducers offer an option of a solid or hollow output shaft and feature an adjustable mounting placement. Both the SW-1 and the SW-5, however, can endure shock loading much better than other reduction gearbox styles, making them well suited for demanding applications.

Worm Gear Reducers also referred to as worm gearbox or worm velocity reducers. Worm gear reducers are used for speed reduction and increasing the torque for electrical engine drives. You can decide to attach your NEMA electric motor to the reducer utilizing the NEMA C encounter flange or make use of a coupling. If you need a coupling for the output or input shaft discover our coupling section for choosing the coupling. You can expect four assemblies left hand and right hands and double result shaft and shaft insight and shaft output. Interchangeable with the majority of worm gear manufactures.

Ever-Power DDVM series triple-reduction worm gear speed reducers are available in ratios from 5000:1 to 175,000:1 and middle distances from 7” to 20” (larger sizes available 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 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 are available in four configurations: horizontal, vertical, shafted, and shaft installed.
These reducers are perfect for water/waste-water apparatus drive applications such as for example thickeners and clarifiers, which need a vertical 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 various 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 versions are 56C or 145TC flange mount with either right, remaining or dual result shafts or a hollow bore output. The indirect drive models are shaft input-shaft output boxes for use with sprocket or pulley drive systems. They offer an effective low cost 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 have to determine the required torque and assistance factor for the application form. Click on “Specs” above for a table that will aid in identifying the service aspect. For service elements above 1.0, multiply the mandatory torque by the provider factor.
