One reduction worm gearing offers high ratio reduction with few moving parts in a close-coupled compact drive. The proper angle set up of driving-to-driven machine takes a minimum of space. Input and result shafts can be prolonged in either or both directions in horizontal or vertical arrangements adaptable to any mounting requirement. Efficient motor speeds are decreased to sluggish speed requirements of several industrial machines in a single reduction.

The exclusive usage of the involute Helicoid Thread form (with leaving side contact) on the worm and gear offers high efficiencies, and long service life. The hardened ground and polished alloy metal worm develops a smooth, work hardened surface area on the bronze equipment. For this reason worm gears wear in and improve with extented service while other gears are wearing out. worm gear speed reducer Ever-Power offers a wide collection of model configurations, sizes, ratios, and components from our standard product line.
Fabricated Designs
If the application involves severe shock loads or possible housing damage from external sources (as in steel mills or mobile products 
applications) Ever-Power can provide fabricated steel housings with up to a 48″ center distances. Fabricated housings provide maximum rigidity and strength which allows the tranny of higher horsepower levels than are feasible with regular cast iron models. Extra heavy part plates connect the worm and gear shaft bearing facilitates, assuring proper meshing of the apparatus 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 offer custom swiftness and reversed engineered reducers for the application, be it a new project or a direct drop-in replacement for a competitor’s speed reducer. Fabricated steel reducers enable Ever-Power to match a competitor’s footprint, centerline, and shaft height allowing a primary drop-in replacement saving the customer 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 metal worm. This combination develops a soft, work-hardened mating surface area of the bronze gear which improves with prolonged service.
Worm gearing is a class of gear reducers that utilizes right angle, nonintersecting shafts. This style of reducer provides soft and quiet operation and allows for the likelihood of large quickness reductions. These gears are available from share in a wide selection of ratios, from as low as 4:1 up to 3600:1. The compact design and structure allows worm gear reducers to be placed in a relatively small space. Thus, very high reductions in a limited package size can be achieved with this configuration. Our worm gear features the constant sliding tooth action between worm and one’s teeth. This escalates the tolerance for large loads and shock loads. Worm gear drives provide users high reducing capacity for relatively low cost when compared to 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 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 includes a right angle result orientation. This type of reduction gear container is normally used to take a rated motor acceleration and create a low speed result with higher torque worth based on the reduction ratio. They often can resolve space-saving problems since the worm gear reducer is one of the sleekest reduction gearboxes available due to the small diameter of its output gear.
worm gear reducerWorm equipment reducers are also a favorite type of rate reducer because they offer the greatest speed decrease in the tiniest package. With a high 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 are available in tuning instruments, medical testing 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 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 of these options are produced with tough compression-molded glass-fill polyester housings for a durable, long lasting, light-weight speed reducer that’s also compact, noncorrosive, and nonmetallic.
Features
Our worm equipment reducers offer a choice of a good or hollow result shaft and feature an adjustable mounting placement. Both the SW-1 and the SW-5, however, can withstand shock loading much better than other decrease gearbox styles, making them perfect for demanding applications.

Worm Gear Reducers also referred to as worm gearbox or worm acceleration reducers. Worm equipment reducers are used for speed decrease and raising the torque for electric powered motor drives. You can decide to install your NEMA engine to the reducer by using the NEMA C encounter flange or use a coupling. If you need a coupling for the result or input shaft observe our coupling section for choosing the coupling. You can expect four assemblies left hands and right hand and double result shaft and shaft insight and shaft result. Interchangeable with most worm gear manufactures.

Description
The HDR Series worm gear reducers are found 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 install with either right, left or dual result shafts or a hollow bore result. The indirect drive models are shaft input-shaft output boxes for make use of with sprocket or pulley drive systems. They provide an effective low cost solution to speed reduction and improved 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 required torque and service factor for the application. Click on “Specs” above for a table that will assist in determining the service element. For service factors above 1.0, multiply the mandatory torque by the provider factor.
