worm gear speed reducer
Single reduction worm gearing offers high ratio reduction with couple of moving parts in a close-coupled compact drive. The proper angle arrangement of driving-to-driven machine requires a the least space. Input and result shafts can be prolonged in either or both directions in horizontal or vertical arrangements adaptable to any mounting requirement. Efficient engine speeds are decreased to gradual speed requirements of several industrial machines in a single reduction.

The exclusive use of the involute Helicoid Thread form (with leaving side contact) on the worm and gear offers high efficiencies, and lengthy service life. The hardened ground and polished alloy metal worm develops a even, work hardened surface on the bronze equipment. Because of this worm gears use in and improve with extented service while other gears are wearing out. Ever-Power offers a broad collection of model configurations, sizes, ratios, and components from our standard products.
Fabricated Designs
If your application involves serious shock loads or possible 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 maximum rigidity and strength which allows the transmission of higher horsepower levels than are possible with standard cast iron units. Extra heavy aspect plates connect the worm and gear shaft bearing facilitates, assuring correct meshing of the apparatus under all load conditions. In smaller sizes, fabricated steel reducers are interchangeable with Ever-Power standard cast iron reducers.
Custom Designs
Ever-Power can offer custom quickness and reversed engineered reducers for the application, be it a new project or a direct drop-in replacement for a competitor’s acceleration reducer. Fabricated steel reducers allow Ever-Power to match a competitor’s footprint, centerline, and shaft elevation allowing a direct drop-in replacement saving the customer time and money.
Long – Quiet Life
All worm gears in Ever-Power reducers are produced from phosphorous bronze. Our design also includes a hardened, surface and polished alloy steel worm. This mixture develops a easy, work-hardened mating surface area 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 likelihood of large acceleration reductions. These 
gears can be found from share in a wide variety of ratios, from as low as 4:1 up to 3600:1. The small design and structure allows worm gear reducers to be placed in a comparatively small space. Thus, high reductions in a limited package size may be accomplished with this configuration. Our worm equipment features the constant sliding tooth actions between worm and the teeth. This escalates the tolerance for weighty loads and shock loads. Worm gear drives provide users high reducing convenience of relatively low cost when compared to some other types of gearing.
The utilization 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.
Ever-Power worm gear reducer gearbox series base on years of experiences uses designed teeth surface area with unsurpassed torque transfer efficiency with great overall performance, efficency and price.Worm gear system transmits power through sliding contact, leading to extremely low vibration , noise, little backlash and self-locking property
-Housing:Onetime we casting creats great rigidity for severe impacts. Outer cooling fins and internal lubrication essential oil diversion channel style to increase heat dissipation.
-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 includes a worm pinion insight, an output worm equipment, and features a right angle output orientation. This kind of reduction gear package is normally used to take a rated motor swiftness and create a low speed result with higher torque worth based on the decrease ratio. They often times can resolve space-saving problems because the worm gear reducer is among 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 provide the greatest speed decrease in the smallest package. With a high ratio of speed reduction and high torque result multiplier, it’s unsurprising that lots of power transmission systems utilize a worm equipment reducer. Some of the most typical applications for worm gears can be found in tuning instruments, medical tests equipment, elevators, protection 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 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 these options are produced with durable 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 good or hollow result shaft and show an adjustable mounting position. Both SW-1 and the SW-5, nevertheless, can withstand shock loading better than other decrease gearbox designs, making them perfect for demanding applications.

Worm Equipment Reducers also called worm gearbox or worm swiftness reducers. Worm equipment reducers are utilized for speed decrease and raising the torque for electric powered electric motor drives. You can choose to install your NEMA motor to the reducer by using the NEMA C face flange or use a coupling. If you want a coupling for the result or input shaft see 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 most worm gear manufactures.

Description
The HDR Series worm gear reducers are found in low to moderate horsepower applications to lessen 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, still left or dual output shafts or a hollow bore result. The indirect drive versions are shaft input-shaft result boxes for make use of with sprocket or pulley drive systems. They provide an effective low cost solution to speed decrease and improved torque, with higher tolerances for shock loading than helical equipment reducers.
In order to decide on a gearbox speed reducer, you will need to determine the mandatory torque and service factor for the application. Click on “Specifications” above for a desk that will assist in determining the service factor. For service factors above 1.0, multiply the required torque by the support factor.
