worm gear speed reducer

One reduction worm gearing provides high ratio reduction with few moving parts in a close-coupled small drive. The right angle arrangement of driving-to-driven machine takes a the least space. Input and output shafts can be extended in either or both directions in horizontal or vertical arrangements adaptable to any installation requirement. Efficient engine speeds are decreased to gradual speed requirements of many industrial machines in one reduction.

The exclusive use 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 even, work hardened surface on the bronze equipment. Because of this worm gears put on in and improve with extented service while other gears are wearing out. Ever-Power offers a broad collection of model configurations, sizes, ratios, and components from our standard product line.
Fabricated Designs
If your application involves serious shock loads or feasible housing damage from external sources (as in steel mills or mobile products applications) Ever-Power can offer fabricated steel housings with up to 48″ center distances. Fabricated housings provide maximum rigidity and strength that allows the tranny of higher horsepower amounts than are feasible with regular cast iron products. Extra heavy side plates connect the worm and gear shaft bearing supports, assuring proper meshing of the gear 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 speed and reversed engineered reducers for your application, be it a new project or a primary 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 includes a hardened, surface and polished alloy steel worm. This mixture develops a smooth, work-hardened mating surface area of the bronze gear which enhances with prolonged service.
Worm gearing is a course of gear reducers that utilizes correct angle, nonintersecting shafts. This form of worm gear speed reducer reducer provides even and quiet procedure and allows for the likelihood of large quickness reductions. These gears are available from share in a wide variety of ratios, from only 4:1 up to 3600:1. The small design and structure allows worm gear reducers to be positioned in a comparatively small space. Thus, very high reductions in a limited package size may be accomplished with this configuration. Our worm equipment features the continuous sliding tooth action between worm and the teeth. This escalates the tolerance for large loads and shock loads. Worm gear drives provide users high reducing convenience of relatively low cost in comparison with 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 type of reduction gear box which includes a worm pinion insight, an output worm gear, and includes a right angle output orientation. This kind of reduction gear box is normally used to have a rated motor acceleration and create a low speed result with higher torque value based on the reduction ratio. They often can solve space-saving problems because the worm equipment reducer is among the sleekest decrease gearboxes available due to the small diameter of its output gear.
worm gear reducerWorm equipment reducers are also a favorite type of speed reducer because they offer the greatest speed reduction in the smallest package. With a higher ratio of speed decrease and high torque result 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 examining equipment, elevators, protection 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 can be found 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 these options are manufactured with rugged compression-molded glass-fill up 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 a choice of a solid or hollow output shaft and show an adjustable mounting position. Both the SW-1 and the SW-5, however, can withstand shock loading much better than other decrease gearbox designs, making them perfect for demanding applications.

Worm Equipment Reducers also known as worm gearbox or worm swiftness reducers. Worm equipment reducers are used for speed reduction and increasing the torque for electric powered motor drives. You can choose to install your NEMA motor to the reducer utilizing the NEMA C encounter flange or make use of a coupling. If you want a coupling for the result or input shaft see our coupling section for choosing the coupling. You can expect four assemblies left hands and right hands and double result shaft and shaft input and shaft result. Interchangeable with most worm gear manufactures.

Ever-Power DDVM series triple-reduction worm gear speed reducers can be found 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 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 mounted.
These reducers are well suited for water/waste-water apparatus drive applications such as for example thickeners and clarifiers, which need a vertical down shaft. Other available configurations also make Ever-Power triple decrease reducers perfect for use on mixers, elevators, solar panels, astronomical telescopes, indexing tables, hoists, conveyors, or additional process or components handling systems where large 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 are available in direct or indirect drive, direct drive versions are 56C or 145TC flange attach with either right, still left or dual output shafts or a hollow bore result. The indirect drive versions 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 decrease and improved torque, with higher tolerances for shock loading than helical equipment reducers.
In order to select a gearbox speed reducer, you will need to determine the mandatory torque and program factor for the application. Click on “Specifications” above for a desk that will assist in identifying the service element. For service elements above 1.0, multiply the mandatory torque by the assistance factor.
