worm gear speed reducer

Solitary reduction worm gearing provides high ratio reduction with couple of shifting parts in a close-coupled compact drive. The right angle set up of driving-to-driven machine takes a the least 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 decreased to slower speed requirements of many 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 long service lifestyle. The hardened floor and polished alloy metal worm develops a clean, work hardened surface area on the bronze gear. For this reason worm gears use in and improve with extented service while additional gears are deteriorating. EP offers a broad selection of model configurations, sizes, ratios, and components from our standard products.
Fabricated Designs
If the application involves serious shock loads or possible housing damage from external sources (as in steel mills or mobile gear applications) EP can offer fabricated steel housings with up to a 48″ center distances. Fabricated housings provide maximum rigidity and strength that allows the transmission of higher horsepower amounts than are possible with regular cast iron systems. Extra heavy part plates connect the worm and equipment shaft bearing supports, assuring correct meshing of the apparatus under all load conditions. In smaller sized sizes, fabricated steel reducers are interchangeable with EP standard cast iron reducers.
Custom Designs
EP can provide custom velocity and reversed engineered reducers for the application, be it a fresh project or a direct drop-in replacement for a competitor’s velocity reducer. Fabricated metal reducers allow EP to complement a competitor’s footprint, centerline, and shaft height allowing a primary drop-in substitute 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, surface and polished alloy metal worm. This mixture develops a even, work-hardened mating surface area of the bronze gear which boosts with prolonged service.
Worm gearing is a class of equipment reducers that utilizes right angle, nonintersecting shafts. This form of reducer provides simple and quiet procedure and permits the possibility of large swiftness reductions. These gears are available from stock in a wide selection of ratios, from only 4:1 to as much as 3600:1. The small design and structure allows worm gear reducers to be placed in a comparatively small space. Thus, high reductions in a restricted 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 provide 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 make use of worm gearing are: conveyors, mixers and bucket elevators.

A worm gear reducer is one kind of reduction gear box which consists of a worm pinion input, an output worm gear, and includes a right angle result orientation. This kind of reduction gear package is normally used to have a rated motor speed and produce a low speed output with higher torque value based on the decrease ratio. They often times can resolve space-saving problems because 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 favorite type of velocity reducer because they provide the greatest speed decrease 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 make use of a worm equipment reducer. Some of the most typical 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 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 produced with durable 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 gear reducers offer a choice of a solid or hollow output shaft and show an adjustable mounting placement. Both the SW-1 and the SW-5, nevertheless, can endure shock loading much better than other decrease gearbox designs, making them perfect for demanding applications.

Worm Equipment Reducers also referred to as worm gearbox or worm speed reducers. Worm gear reducers are utilized for speed reduction and increasing the torque for electrical engine drives. You can choose to attach your NEMA electric motor to the reducer by using the NEMA C encounter flange or make use of a coupling. If you need a coupling for the output or input shaft find our coupling section for selecting a coupling. We offer four assemblies left hands and right hands and double output shaft and shaft insight 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 can be found in direct or indirect drive, direct drive models are 56C or 145TC flange attach with either right, remaining or dual result shafts or a hollow bore output. The indirect drive models are shaft input-shaft result boxes for make use of with sprocket or pulley drive systems. They provide an effective low priced solution to speed decrease and increased torque, with higher tolerances for shock loading than helical equipment reducers.
In order to decide on a gearbox speed reducer, you will have to determine the mandatory torque and support factor for the application. Click on “Specifications” above for a table that will assist in identifying the service factor. For service elements above 1.0, multiply the required torque by the assistance factor.
