Single reduction worm gearing offers high ratio reduction with couple of moving parts in a close-coupled small 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 plans adaptable to any mounting requirement. Efficient motor speeds are reduced to sluggish speed requirements of many 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 existence. The hardened surface and polished alloy metal worm develops a even, work hardened surface on the bronze gear. Because of this worm gears use in and improve with prolonged service while various other gears are wearing out. EP offers a broad collection of model configurations, sizes, ratios, and add-ons from our standard products.
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 a 48″ center distances. Fabricated housings provide optimum rigidity and strength which allows the transmission of higher horsepower levels than are feasible with regular cast iron devices. Extra heavy aspect plates connect the worm and gear shaft bearing supports, assuring correct meshing of the gear under all load conditions. In smaller sized sizes, fabricated steel reducers are interchangeable with EP standard cast iron reducers.
Custom Designs
EP can offer custom quickness and reversed engineered reducers for your application, be it a fresh project or a direct drop-in replacement for a competitor’s acceleration reducer. Fabricated steel reducers allow EP to complement 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 EP reducers are produced from phosphorous bronze. Our design also includes a hardened, floor and polished alloy metal worm. This mixture develops a easy, work-hardened mating surface area of the bronze gear which increases with prolonged service.
Worm gearing is a course of gear reducers that utilizes right angle, nonintersecting shafts. This form of reducer provides smooth and quiet procedure and allows for the probability of large rate reductions. These gears can be found from share in a wide selection of ratios, from as low as 4:1 to as much as 3600:1. The compact design and construction allows worm equipment reducers to be positioned in a comparatively small space. Thus, high reductions in a restricted package size can be achieved with this configuration. Our worm gear features the constant sliding tooth action between worm and the teeth. This increases the tolerance for large loads and shock loads. Worm gear drives provide users high reducing convenience of relatively low cost in comparison with 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 container 
which consists of a worm pinion insight, an output worm gear, and includes a right angle output orientation. This type of reduction gear box is generally used to have a rated motor quickness and produce a low speed output with higher torque value based on the decrease ratio. They often times can solve space-saving problems because the worm equipment reducer is one of the sleekest reduction gearboxes available because of the small diameter of its result gear.
worm gear reducerWorm equipment reducers are also a favorite type of quickness reducer because they provide the greatest speed decrease in the tiniest package. With a higher ratio of speed reduction and high torque result multiplier, it’s unsurprising that lots of 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 screening 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 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 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 an option of a solid or hollow result shaft and feature an adjustable mounting placement. Both the SW-1 and the SW-5, nevertheless, can endure shock loading better than other decrease gearbox styles, making them well suited for demanding applications.

Worm Equipment Reducers also known as worm gearbox or worm rate reducers. Worm equipment reducers are used for speed decrease and increasing the torque for electric engine drives. You can choose to install your NEMA motor to the reducer utilizing the NEMA C face flange or make use of a coupling. If you need a coupling for the output or input shaft discover our coupling section for choosing the coupling. You can expect four assemblies left hand and right hand and double output shaft and shaft input and shaft output. Interchangeable with most 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 versions are 56C or 145TC flange install with either right, still left or dual output shafts or a hollow bore output. The indirect drive versions are shaft input-shaft result boxes for use with sprocket or pulley drive systems. They offer an effective low cost solution to speed decrease and improved torque, with higher tolerances for shock loading than helical gear reducers.
In order to decide on a gearbox speed reducer, you will have to determine the mandatory torque and assistance factor for the application. Click on “Specs” above for a table that will aid in determining the service factor. For service factors above 1.0, multiply the mandatory torque by the assistance factor.
