worm gear speed reducer

One reduction worm gearing provides high ratio reduction with couple of shifting parts in a close-coupled small drive. The proper angle arrangement of driving-to-driven machine takes a minimum of space. Input and output shafts can be extended in either or both directions in horizontal or vertical plans adaptable to any mounting requirement. Efficient electric motor speeds are decreased to gradual speed requirements of several industrial machines in a single reduction.

The exclusive utilization of the involute Helicoid Thread form (with departing side contact) on the worm and gear offers high efficiencies, and long service existence. The hardened ground and polished alloy metal worm develops a even, work hardened surface area on the bronze equipment. For this reason 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 add-ons from our standard product line.
Fabricated Designs
If your application involves severe shock loads or feasible housing damage from external sources (as in steel mills or mobile products applications) EP can provide fabricated steel housings with up to a 48″ center distances. Fabricated housings provide optimum rigidity and strength that allows the tranny of higher horsepower amounts than are possible with standard cast iron products. Extra heavy aspect plates connect the worm and gear shaft bearing facilitates, assuring correct meshing of the gear under all load circumstances. In smaller sized sizes, fabricated metal reducers are interchangeable with EP regular cast iron reducers.
Custom Designs
EP can provide custom speed and reversed engineered reducers for the application, be it a new project or a direct drop-in alternative to a competitor’s velocity reducer. Fabricated metal reducers allow EP to match 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 style also incorporates a hardened, floor and polished alloy steel worm. This combination develops a smooth, work-hardened mating surface of the bronze gear which boosts with prolonged service.
Worm gearing is a class of gear reducers that utilizes right angle, nonintersecting shafts. This form of reducer provides clean and quiet procedure and allows for the probability of large speed reductions. These gears are available from stock in a wide variety of ratios, from only 4:1 up to 3600:1. The small design and structure allows worm equipment reducers to be positioned in a comparatively small space. Thus, high reductions in a limited package size can be achieved with this configuration. Our worm gear features the constant sliding tooth actions between worm and one’s 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 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 utilize worm gearing are: conveyors, mixers and bucket elevators.

A worm gear reducer is one kind of reduction gear container which includes a worm pinion input, an output worm gear, and features a right angle result orientation. This type of reduction gear package is generally used to take a rated motor quickness and create a low speed output with higher torque value based on the decrease ratio. They often can solve 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 quickness reducer because they provide the greatest speed decrease in the tiniest package. With a high ratio of speed reduction and high torque output multiplier, it’s unsurprising that many power transmission systems utilize a worm equipment reducer. Some of the most typical applications for worm gears can be found 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 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 of these options are produced with rugged compression-molded glass-fill up polyester housings for a long lasting, long lasting, light weight speed reducer that is also compact, noncorrosive, and nonmetallic.
Features
Our worm gear reducers offer a choice of a solid or hollow result shaft and feature an adjustable mounting position. Both the SW-1 and the SW-5, however, can withstand shock loading better than other reduction gearbox styles, making them ideal for demanding applications.

Worm Equipment Reducers also referred to as worm gearbox or worm speed reducers. Worm gear reducers are used for speed decrease and raising the torque for electric motor drives. You can decide to attach your NEMA motor to the reducer by using the NEMA C encounter flange or make use of a coupling. If you want a coupling for the output or input shaft see 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. See data sheet in product overview for diamensions. If you don’t see your type, please Contact Us.

Description
The HDR Series worm equipment 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, still left or dual result shafts or a hollow bore result. The indirect drive models are shaft input-shaft output boxes for use with sprocket or pulley drive systems. They offer an effective low priced solution to speed decrease and improved torque, with higher tolerances for shock loading than helical equipment reducers.
In order to select a gearbox speed reducer, you will need to determine the required torque and provider factor for the application. Click on “Specs” above for a table that will aid in identifying the service element. For service elements above 1.0, multiply the required torque by the service factor.
