worm gear speed reducer

One reduction worm gearing provides high ratio reduction with few moving parts in a close-coupled compact drive. The proper angle arrangement of driving-to-driven machine requires a minimum of space. Input and result shafts can be extended in either or both directions in horizontal or vertical arrangements adaptable to any installation requirement. Efficient engine speeds are reduced 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 provides for high efficiencies, and lengthy service existence. The hardened surface and polished alloy metal worm develops a even, work hardened surface area on the bronze gear. Because of this 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 components from our standard product line.
Fabricated Designs
If your application involves severe shock loads or possible housing damage from external sources (as in steel mills or mobile devices applications) EP can offer fabricated steel housings with up to a 48″ center distances. Fabricated housings provide maximum rigidity and strength that allows the transmitting of higher horsepower amounts than are feasible with regular cast iron products. Extra heavy side plates connect the worm and gear shaft bearing facilitates, 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 acceleration and reversed engineered reducers for the application, be it a fresh project or a direct drop-in alternative to a competitor’s acceleration reducer. Fabricated metal reducers enable 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 style also incorporates a hardened, ground and polished alloy steel worm. This combination develops a easy, work-hardened mating surface of the bronze gear which increases with prolonged service.
Worm gearing is a class of equipment reducers that utilizes correct angle, nonintersecting shafts. This form of reducer provides easy and quiet operation and allows for the possibility of large acceleration reductions. These gears can be found from share in a wide variety of ratios, from as low as 4:1 to as much as 3600:1. The small design and construction allows worm gear reducers to be placed in a comparatively 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 actions between worm and one’s teeth. This increases 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 use 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 package which includes a worm pinion insight, an output worm equipment, and includes a right angle output orientation. This type of reduction gear package is normally used to take a rated motor velocity and produce a low speed result with higher torque worth based on the reduction 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 rate reducer because they provide the greatest speed reduction in the smallest package. With a higher ratio of speed decrease and high torque output multiplier, it’s unsurprising that lots of power transmission systems utilize a worm equipment reducer. Some of the most common applications for worm gears can be found in tuning instruments, medical examining equipment, elevators, security gates, and conveyor belts.
SW-1 and SW-5
Torque Transmission provides 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 these options are produced with tough 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 equipment 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, nevertheless, can endure shock loading better than other reduction gearbox designs, making them well suited for demanding applications.

Worm Equipment Reducers also referred to as worm gearbox or worm rate reducers. Worm equipment reducers are utilized for speed reduction and raising the torque for electrical electric motor drives. You can decide to install your NEMA engine to the reducer utilizing the NEMA C encounter flange or use a coupling. If you need a coupling for the result or input shaft discover our coupling section for choosing the coupling. You can expect four assemblies left hands and right hands and double output shaft and shaft insight and shaft result. Interchangeable with the majority of worm gear manufactures.

Description
The HDR Series worm equipment reducers are used in low to moderate horsepower applications to lessen 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, still 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 reduction and increased 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 service factor for the application form. Click on “Specifications” above for a table that will assist in identifying the service aspect. For service elements above 1.0, multiply the mandatory torque by the program factor.
