One reduction worm gearing offers high ratio reduction with couple of shifting parts in a close-coupled compact drive. The proper angle arrangement of driving-to-driven machine takes 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 engine speeds are reduced to gradual speed requirements of many industrial machines in a single reduction.

The exclusive use of the involute Helicoid Thread form (with leaving side contact) on the worm and gear provides for high efficiencies, and lengthy service lifestyle. The hardened surface and polished alloy steel worm develops a smooth, work hardened surface area on the bronze equipment. For this reason worm gears use in and improve with prolonged service while various other gears are deteriorating. EP offers a wide collection of model configurations, sizes, ratios, and add-ons from our standard products.
Fabricated Designs
If the application involves severe shock loads or possible housing damage from external sources (as in steel mills or mobile gear applications) EP can offer fabricated steel housings with up to a 48″ center distances. Fabricated housings provide maximum rigidity and strength which allows the tranny of higher horsepower amounts than are possible with regular cast iron units. Extra heavy side plates connect the worm and equipment shaft bearing supports, assuring appropriate meshing of the apparatus under all load conditions. In smaller sizes, fabricated metal reducers are interchangeable with EP regular cast iron reducers.
Custom Designs
EP can provide custom acceleration and reversed engineered reducers for your application, be it a new project or a primary drop-in replacement for a competitor’s speed reducer. Fabricated metal reducers allow EP to complement a competitor’s footprint, centerline, and shaft height allowing a direct drop-in substitute saving the customer time and money.
Long – Quiet Life
All worm gears in EP reducers are produced 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 equipment which improves with prolonged service.
Worm gearing is a class of equipment reducers that utilizes right angle, nonintersecting shafts. This form of reducer provides smooth and quiet operation and allows for the likelihood of large quickness reductions. These gears can be found from stock in a wide variety of ratios, from as low as 4:1 to as much as 3600:1. The small design and structure allows worm equipment reducers to be positioned in a comparatively small space. Thus, very high reductions in a restricted package size may be accomplished with this configuration. Our worm gear features the continuous 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 in comparison with some other types of gearing.
The use 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 container which consists of a worm pinion insight, an output worm gear, and features a right angle output orientation. This type of reduction gear container 
is normally used to take a rated motor velocity and produce a low speed result with higher torque worth based on the reduction ratio. They often can resolve space-saving problems because the worm gear 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 favorite type of swiftness reducer because they provide the greatest speed decrease in the smallest package. With a higher ratio of speed decrease and high torque output multiplier, it’s unsurprising that lots of power transmission systems utilize a worm equipment reducer. Some of the most common applications for worm gears are available in tuning instruments, medical tests equipment, elevators, security gates, and conveyor belts.
SW-1 and SW-5
Torque Transmission offers two sizes of worm equipment 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 these options are manufactured with rugged compression-molded glass-fill up polyester housings for a long lasting, 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 result shaft and feature an adjustable mounting placement. Both SW-1 and the SW-5, however, can endure shock loading much better than other decrease gearbox designs, making them ideal for demanding applications.

Worm Gear Reducers also called worm gearbox or worm rate reducers. Worm equipment reducers are used for speed reduction and increasing the torque for electrical electric motor drives. You can choose to install your NEMA motor to the reducer utilizing the NEMA C face flange or use a coupling. If you want a coupling for the result or input shaft discover our coupling section for selecting a coupling. We offer four assemblies left hand and right hand and double output shaft and shaft input and shaft result. Interchangeable with most worm gear manufactures.

Description
The HDR Series worm gear reducers are used 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 versions are 56C or 145TC flange mount with either right, left or dual result shafts or a hollow bore result. The indirect drive models are shaft input-shaft result boxes for use with sprocket or pulley drive systems. They offer an effective low priced solution to speed reduction and improved torque, with higher tolerances for shock loading than helical equipment reducers.
In order to decide on a gearbox speed reducer, you will have to determine the required torque and support factor for the application. Click on “Specifications” above for a table that will assist in determining the service element. For service elements above 1.0, multiply the required torque by the provider factor.
