One reduction worm gearing offers high ratio reduction with couple of shifting parts in a close-coupled compact drive. The proper angle set up 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 motor speeds are reduced to sluggish speed requirements of several industrial machines in a single reduction.

The exclusive use of the involute Helicoid Thread form (with leaving side contact) on the worm and gear offers high efficiencies, and long service existence. The hardened surface and polished alloy steel worm develops a clean, work hardened surface area on the bronze equipment. For this reason worm gears put on in and improve with prolonged service while other gears are deteriorating. EP offers a wide selection of model configurations, sizes, ratios, and add-ons 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 devices applications) EP can provide fabricated steel housings with up to 48″ center distances. Fabricated housings provide maximum rigidity and strength that allows the transmitting of higher horsepower levels than are feasible with standard cast iron systems. Extra heavy aspect plates connect the worm and gear shaft bearing supports, assuring correct meshing of the gear under all load circumstances. In smaller sizes, fabricated steel reducers are interchangeable with EP standard cast iron reducers.
Custom Designs
EP can offer custom quickness and reversed engineered reducers for the application, be it a fresh project or a direct drop-in replacement for a competitor’s speed reducer. Fabricated metal reducers enable EP to complement a competitor’s footprint, centerline, and shaft elevation allowing a primary drop-in alternative saving the customer time and money.
Long – Quiet Life
All worm gears in EP reducers are produced from phosphorous bronze. Our design also incorporates a hardened, floor and polished alloy metal worm. This mixture develops a even, work-hardened mating surface area of the bronze gear which enhances with prolonged service.
Worm gearing is a class of gear reducers that utilizes correct angle, nonintersecting shafts. This form of reducer provides smooth and quiet procedure and permits the possibility of large quickness reductions. These gears can be found from share in a wide variety of ratios, from as low as 4:1 up to 3600:1. The compact design and construction allows worm equipment reducers to be placed in a comparatively small space. Thus, very high reductions in a restricted package size can be achieved with this configuration. Our worm equipment features the constant sliding tooth actions between worm and the 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 make use of worm gearing are: conveyors, mixers and bucket elevators.

A worm gear reducer is one kind of reduction gear container which consists of a worm pinion insight, an output worm equipment, and includes a right angle output orientation. This kind of reduction gear package is generally used to take a rated motor swiftness and produce a low speed output with higher torque worth based on the reduction ratio. They often can resolve space-saving problems since the worm equipment reducer is among the sleekest reduction gearboxes available due to the little diameter of its output gear.
worm gear reducerWorm equipment reducers are also a popular type of acceleration reducer because they provide the greatest speed reduction in the tiniest package. With a higher ratio of speed decrease and high torque output multiplier, it’s unsurprising that many power transmission systems utilize a worm gear reducer. Some of the most common 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 offers two sizes of worm gear 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 tough compression-molded glass-fill polyester housings for a long lasting, long lasting, light weight speed reducer that is also compact, noncorrosive, and nonmetallic.
Features
Our worm equipment reducers offer a choice of a solid or hollow output shaft and feature an adjustable mounting position. Both the SW-1 and the SW-5, nevertheless, can endure shock loading much better than other decrease gearbox designs, making them well suited for demanding applications.

Worm Gear Reducers also known as worm gearbox or worm acceleration reducers. Worm gear reducers are utilized for speed reduction and increasing the torque for electric engine drives. You can choose to mount your NEMA engine to the reducer utilizing the NEMA C face 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 hand and right hands and double output shaft and shaft insight and shaft output. Interchangeable with the majority of 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 versions are 56C or 145TC flange attach with either right, remaining 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 provide an effective low priced 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 required torque and support factor for the application form. Click on “Specs” above for a desk that will assist in identifying the service aspect. For service factors above 1.0, multiply the mandatory torque by the service factor.
