worm gear speed reducer
Solitary reduction worm gearing provides 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 the least space. Input and output shafts can be prolonged in either or both directions in horizontal or vertical arrangements adaptable to any installation requirement. Efficient engine speeds are decreased 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 offers high efficiencies, and lengthy service lifestyle. The hardened floor and polished alloy steel worm develops a even, work hardened surface area on the bronze equipment. Because of this worm gears wear in and improve with prolonged service while other gears are deteriorating. Ever-Power offers a broad collection of model configurations, sizes, ratios, and add-ons from our standard products.
Fabricated Designs
If your 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 tranny of higher horsepower levels than are feasible with standard cast iron units. Extra heavy side plates connect the worm and equipment shaft bearing supports, assuring correct meshing of the apparatus under all load conditions. In smaller sized sizes, fabricated metal reducers are interchangeable with Ever-Power regular cast iron reducers.
Custom Designs
Ever-Power can offer custom rate and reversed engineered reducers for your application, be it a fresh project or a direct drop-in replacement for a competitor’s quickness reducer. Fabricated steel reducers enable Ever-Power to match 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 style also includes a hardened, ground and polished alloy metal worm. This combination develops a easy, work-hardened mating surface of the bronze gear which boosts with prolonged service.
Worm gearing is a course of gear reducers that utilizes right angle, nonintersecting shafts. This style of reducer provides simple and quiet operation and permits the possibility of large quickness reductions. These gears are available from stock in a wide selection of ratios, from as low as 4:1 up to 3600:1. The small design and structure allows worm equipment reducers to be positioned in a comparatively small space. Thus, high reductions in a restricted package size can be achieved with this configuration. Our worm equipment features the continuous sliding tooth actions between worm and one’s teeth. This escalates the tolerance for large loads and shock loads. Worm gear drives offer users 
high reducing convenience of 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 make use of worm gearing are: conveyors, mixers and bucket elevators.

A worm gear reducer is one type of reduction gear package which contains a worm pinion input, an output worm equipment, and features a right angle result orientation. This kind of reduction gear box is generally used to take a rated motor acceleration and create a low speed result with higher torque value based on the decrease ratio. They often times can solve space-saving problems since the worm equipment reducer is one of the sleekest reduction gearboxes available due to the small diameter of its output gear.
worm gear reducerWorm gear reducers are also a favorite 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 make use of a worm equipment reducer. Some of the most typical applications for worm gears are available in tuning instruments, medical screening 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 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 produced with tough compression-molded glass-fill 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 good or hollow output shaft and show an adjustable mounting placement. Both the SW-1 and the SW-5, nevertheless, can withstand shock loading better than other reduction gearbox designs, making them well suited for demanding applications.

Worm Equipment Reducers also called worm gearbox or worm swiftness reducers. Worm gear reducers are used for speed decrease and raising the torque for electric powered motor drives. You can choose to attach your NEMA engine to the reducer by using the NEMA C encounter flange or make use of a coupling. If you want a coupling for the result or input shaft observe our coupling section for selecting a coupling. You can expect four assemblies left hand and right hands and double output shaft and shaft input and shaft output. Interchangeable with many worm gear manufactures.

Ever-Power DDVM series triple-reduction worm gear swiftness reducers are available 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 pounds 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 installed.
These reducers are ideal for water/waste-water equipment drive applications such as for example thickeners and clarifiers, which need a vertical straight 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 other process or components handling systems where large torques/slower speeds are needed.
These reducers are also obtainable with a helical principal reduction stage and are termed the HDVM series

Description
The HDR Series worm equipment 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 models are 56C or 145TC flange attach with either right, still left or dual result shafts or a hollow bore result. The indirect drive versions 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 improved torque, with higher tolerances for shock loading than helical equipment reducers.
In order to decide on a gearbox speed reducer, you will need 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 element. For service factors above 1.0, multiply the mandatory torque by the services factor.
