worm gear speed reducer
Single reduction worm gearing offers high ratio reduction with couple of shifting parts in a close-coupled compact drive. The right angle set up of driving-to-driven machine requires a minimum of space. Input and result shafts can be extended in either or both directions in horizontal or vertical arrangements adaptable to any mounting requirement. Efficient motor speeds are reduced to sluggish speed requirements of several industrial machines in a single 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 life. The hardened ground and polished alloy metal worm develops a even, work hardened surface area on the bronze gear. For this reason worm gears wear in and improve with prolonged service while other gears are wearing out. Ever-Power offers a wide selection of model configurations, sizes, ratios, and components 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 products applications) Ever-Power can offer fabricated steel housings with up to a 48″ center distances. Fabricated housings provide optimum rigidity and strength which allows the tranny of higher horsepower levels than are feasible with standard cast iron models. Extra heavy side plates connect the worm and gear shaft bearing supports, assuring appropriate 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 provide custom rate and reversed engineered reducers for your application, be it a fresh project or a primary drop-in replacement for a competitor’s speed reducer. Fabricated metal reducers enable Ever-Power to match 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 design also incorporates a hardened, ground and polished alloy steel worm. This combination develops a smooth, work-hardened mating surface of the bronze equipment which improves with prolonged service.
Worm gearing is a class of gear reducers that utilizes right angle, nonintersecting shafts. This style of reducer provides smooth and quiet procedure and allows for the likelihood of large swiftness reductions. These gears are available from stock in a wide selection of ratios, from as low as 4:1 to as much as 3600:1. The compact design and building allows worm gear reducers to be placed in a relatively small space. Thus, very high reductions in a restricted package size may be accomplished with this configuration. Our worm equipment features the constant sliding tooth actions between worm and one’s teeth. This escalates the tolerance for heavy loads and shock loads. Worm gear drives provide 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 use worm gearing are: conveyors, mixers and bucket elevators.

A worm equipment reducer is one kind of reduction gear package which includes a worm pinion input, an output worm gear, and features a right angle result orientation. This type of reduction gear box is generally used to have a rated motor acceleration and produce a low speed result with higher torque value based on the reduction ratio. They often times can resolve space-saving problems because the worm equipment reducer is among the sleekest reduction gearboxes available because of 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 reduction in the smallest package. With a higher ratio of speed reduction and high torque result 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 tests 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 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 polyester housings for a long lasting, long lasting, light weight speed reducer that is also compact, non-corrosive, and nonmetallic.
Features
Our worm equipment reducers offer an option of a good 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 styles, making them well suited for demanding applications.

Worm Equipment Reducers also referred to as worm gearbox or worm velocity reducers. Worm equipment reducers are used for speed decrease and raising the torque for electric powered electric 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 need a coupling for the result or input shaft find our coupling section for selecting a coupling. We offer four assemblies left hands and right hands and double result shaft and shaft input and shaft result. Interchangeable with the majority of worm gear manufactures.

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 models are 56C or 145TC flange attach with either right, still left 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 provide an effective low cost solution to speed reduction and increased torque, with higher tolerances for shock loading than helical equipment 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 aid in determining the service element. For service factors above 1.0, multiply the mandatory torque by the service factor.
