Single reduction worm gearing provides high ratio reduction with few shifting parts in a close-coupled small drive. The proper angle arrangement of driving-to-driven machine takes a the least space. Input and result shafts can be extended in either or both directions in horizontal or vertical plans adaptable to any installation requirement. Efficient engine speeds are reduced to gradual speed requirements of many 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 lifestyle. The hardened surface and polished alloy metal worm develops a smooth, work hardened surface area on the bronze gear. Because of this worm gears wear in and improve with prolonged service while additional gears are deteriorating. EP offers a broad collection of model configurations, sizes, ratios, and accessories from our standard product line.
Fabricated Designs
If the application involves serious shock loads or feasible housing damage from external sources (as in steel mills or mobile gear applications) EP can provide fabricated steel housings with up to 48″ center distances. Fabricated housings provide maximum 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 gear shaft bearing facilitates, assuring correct meshing of the apparatus under all load conditions. In smaller sized sizes, fabricated metal reducers are interchangeable with EP standard cast iron reducers.
Custom Designs
EP can provide custom speed and reversed engineered reducers for the application, be it a new project or a primary drop-in alternative to a competitor’s velocity reducer. Fabricated metal reducers enable EP to match a competitor’s footprint, centerline, and shaft elevation allowing a direct drop-in replacement 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, floor and polished alloy steel worm. This mixture develops a soft, work-hardened mating surface of the bronze equipment which improves with prolonged service.
Worm gearing is a course of equipment reducers that utilizes right angle, nonintersecting shafts. This form of reducer provides smooth and quiet procedure and allows for the possibility of large swiftness reductions. These gears are available from share in a wide variety of ratios, from as low as 4:1 up to 3600:1. The small design and construction allows worm equipment reducers to be placed in a comparatively small space. Thus, very high reductions in a restricted package size may be accomplished with this configuration. Our worm equipment features the continuous sliding tooth actions between worm and one’s teeth. This escalates the tolerance for weighty loads and shock loads. Worm gear drives offer 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 make use of worm gearing are: conveyors, mixers and bucket elevators.

A worm gear reducer is one kind of reduction gear container which includes a worm pinion insight, an output worm equipment, and features a right angle result orientation. This type of reduction gear container is generally used to have a rated motor velocity and produce a low speed output with higher torque worth based on the reduction ratio. They often times can solve space-saving problems since the worm equipment reducer is among the sleekest decrease gearboxes available due to the little diameter of its result 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 utilize a worm equipment reducer. Some of the most common applications for worm gears can be found in tuning instruments, medical tests equipment, elevators, protection 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 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 of these options are manufactured with durable compression-molded glass-fill polyester housings for a durable, long lasting, light weight speed reducer that’s also compact, non-corrosive, and nonmetallic.
Features
Our worm equipment reducers offer a choice of a good or hollow output shaft and show an adjustable mounting placement. Both the SW-1 and the SW-5, nevertheless, can endure shock loading much better than other decrease gearbox designs, making them ideal for demanding applications.

Worm Gear Reducers also referred to as worm gearbox or worm speed reducers. Worm equipment reducers are used for speed decrease and raising the torque for electrical engine drives. You can choose to install 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 output or input shaft observe our coupling section for choosing the coupling. You can expect four assemblies left hand and right hand and double output shaft and shaft insight and shaft output. Interchangeable with many 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 can be found in direct or indirect drive, direct drive versions are 56C or 145TC flange install with either right, left or dual result shafts or a hollow bore output. 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 gear reducers.
In order to select a gearbox speed reducer, you will have to determine the mandatory torque and assistance factor for the application. Click on “Specs” above for a desk that will assist in identifying the service element. For service factors above 1.0, multiply the mandatory torque by the service factor.
