worm gear speed reducer

Single reduction worm gearing offers high ratio reduction with couple of shifting parts in a close-coupled small drive. The right angle arrangement of driving-to-driven machine requires a minimum of space. Input and output shafts can be prolonged 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 one reduction.

The exclusive utilization of the involute Helicoid Thread form (with leaving side contact) on the worm and gear offers high efficiencies, and long service life. The hardened ground and polished alloy steel worm develops a easy, work hardened surface on the bronze gear. Because of this worm gears wear in and improve with prolonged service while various other gears are deteriorating. EP offers a wide collection of model configurations, sizes, ratios, and components from our standard product line.
Fabricated Designs
If the application involves severe shock loads or feasible housing damage from external sources (as in steel mills or mobile apparatus applications) EP can provide fabricated steel housings with up to a 48″ center distances. Fabricated housings provide maximum rigidity and strength which allows the tranny of higher horsepower levels than are feasible with standard cast iron products. Extra heavy aspect plates connect the worm and equipment shaft bearing facilitates, assuring proper meshing of the gear under all load circumstances. In smaller sized sizes, fabricated metal reducers are interchangeable with EP standard cast iron reducers.
Custom Designs
EP can provide custom acceleration and reversed engineered reducers for the application, be it a new project or a primary drop-in alternative to a competitor’s quickness reducer. Fabricated metal reducers allow EP to match a competitor’s footprint, centerline, and shaft height allowing a direct drop-in alternative saving the customer time and money.
Long – Quiet Life
All worm gears in EP reducers are manufactured from phosphorous bronze. Our design also includes a hardened, ground and polished alloy steel worm. This combination develops a clean, work-hardened mating surface area of the bronze gear which increases with prolonged service.
Worm gearing is a class of equipment reducers that utilizes correct angle, nonintersecting shafts. This style of reducer provides clean and quiet procedure and allows for the probability of large acceleration reductions. These gears can be found from stock in a wide selection 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 placed in a relatively small space. Thus, very high reductions in a limited package size can be achieved with this configuration. Our worm equipment features the continuous sliding tooth action between worm and the teeth. This escalates the tolerance for large loads and shock loads. Worm gear drives offer users high reducing convenience of 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 equipment reducer is one type of reduction gear package which includes a worm pinion insight, an output worm equipment, and includes a right angle result orientation. This type of reduction gear package is generally used to have a rated motor acceleration and create a low speed output with higher torque worth based on the decrease ratio. They often times can resolve space-saving problems since the worm equipment reducer is one of the sleekest reduction gearboxes available because of the small diameter of its output gear.
worm gear reducerWorm equipment reducers are also a popular type of swiftness reducer because they offer the greatest speed decrease in the smallest package. With a higher ratio of speed decrease and high torque result multiplier, it’s unsurprising that many power transmission systems utilize a worm gear 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 equipment reducer, the SW-1 and the SW-5 and both can be found 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 manufactured with tough compression-molded glass-fill up polyester housings for a durable, long lasting, light weight speed reducer that’s also compact, noncorrosive, and nonmetallic.
Features
Our worm gear reducers offer a choice of a solid or hollow result shaft and show an adjustable mounting placement. Both 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 Equipment Reducers also referred to as worm gearbox or worm swiftness reducers. Worm gear reducers are utilized for speed reduction and increasing the torque for electric powered electric motor drives. You can choose to install your NEMA electric motor to the reducer by using the NEMA C face flange or make use of 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 hands and right hand and double output shaft and shaft input and shaft result. Interchangeable with many worm gear manufactures. See data sheet in item overview for diamensions. Unless you see your type, make sure you Contact Us.

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 models are 56C or 145TC flange attach with either right, left or dual output 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 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 select a gearbox speed reducer, you will have to determine the required torque and provider factor for the application form. Click on “Specs” above for a table that will assist in determining the service element. For service factors above 1.0, multiply the mandatory torque by the support factor.
