worm gear speed reducer

Single reduction worm gearing offers high ratio reduction with couple of moving parts in a close-coupled small drive. The proper angle set up 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 arrangements adaptable to any mounting requirement. Efficient motor speeds are decreased to slower speed requirements of several industrial machines in a single reduction.

The exclusive use of the involute Helicoid Thread form (with departing side contact) on the worm and gear offers high efficiencies, and lengthy service lifestyle. The hardened floor and polished alloy metal worm develops a even, work hardened surface on the bronze gear. Because of this worm gears put on in and improve with prolonged service while various other gears are wearing out. Ever-Power offers a wide collection of model configurations, sizes, ratios, and accessories from our standard products.
Fabricated Designs
If your application involves severe shock loads or feasible housing damage from external sources (as in steel mills or mobile products applications) Ever-Power can offer fabricated steel housings with up to 48″ center distances. Fabricated housings provide optimum rigidity and strength that allows the transmission of higher horsepower amounts than are possible with standard cast iron systems. Extra heavy side plates connect the worm and equipment shaft bearing facilitates, assuring proper meshing of the apparatus under all load conditions. In smaller sized sizes, fabricated metal reducers are interchangeable with Ever-Power standard cast iron reducers.
Custom Designs
Ever-Power can provide custom swiftness and reversed engineered reducers for your application, be it a new project or a direct drop-in replacement for a competitor’s swiftness reducer. Fabricated metal reducers enable Ever-Power to complement a competitor’s footprint, centerline, and shaft height allowing a direct drop-in alternative saving the client time and money.
Long – Quiet Life
All worm gears in Ever-Power reducers are manufactured from phosphorous bronze. Our style also includes a hardened, surface and polished alloy metal worm. This combination develops a even, work-hardened mating surface of the bronze equipment which enhances with prolonged service.
Worm gearing is a class of equipment reducers that utilizes correct angle, nonintersecting shafts. This style of reducer provides simple and quiet procedure and allows for the possibility of large swiftness reductions. These gears are available from share in a wide selection of ratios, from as low as 4:1 to as much as 3600:1. The compact design and structure allows worm gear reducers to be positioned in a relatively small space. Thus, high reductions in a limited package size may be accomplished with this configuration. Our worm equipment features the constant sliding tooth action between worm and one’s teeth. This increases the tolerance for heavy loads and shock loads. Worm gear drives offer 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.

-Worm Shaft: Manufactured with Carbon alloyed Metal S45C or SCM415, precison machined and carburized to HRC45 or HRC60, then for precision tooth grinding to ensure maximum contacting.
-Worm Wheel: Manufactured with Carbon alloy ALBC2, teeth are machined by precision CNC hobbing machine to sustain high impact.
A worm equipment reducer is one kind of reduction gear box which consists of a worm pinion input, an output worm equipment, and features a right angle result orientation. This kind of reduction gear package is generally used to have a rated motor velocity and produce a low speed result with higher torque value based on the reduction ratio. They often can solve space-saving problems since the worm equipment reducer is one of the sleekest decrease gearboxes available because of the small diameter of its result gear.
worm gear reducerWorm gear reducers are also a favorite type of speed reducer because they offer the greatest speed reduction in the smallest package. With a higher ratio of speed reduction 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 are available in tuning instruments, medical examining 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 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 up polyester housings for a durable, long lasting, light weight speed reducer that’s also compact, non-corrosive, and nonmetallic.
Features
Our worm equipment reducers offer an option of a solid or hollow output shaft and feature an adjustable mounting position. Both the SW-1 and the SW-5, nevertheless, can withstand shock loading much better than other reduction gearbox styles, making them ideal for demanding applications.

Worm Gear Reducers also referred to as worm gearbox or worm velocity reducers. Worm equipment 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 face flange or use a coupling. If you want a coupling for the output or input shaft find 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 the majority of worm gear manufactures.

Description
The HDR Series worm equipment reducers are found 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 models are 56C or 145TC flange attach with either right, still 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 cost solution to speed reduction and improved torque, with higher tolerances for shock loading than helical gear reducers.
In order to decide on a gearbox speed reducer, you will need to determine the required torque and provider factor for the application. Click on “Specifications” above for a desk that will aid in identifying the service factor. For service elements above 1.0, multiply the required torque by the service factor.
