worm gear speed reducer
Solitary reduction worm gearing offers high ratio reduction with few shifting parts in a close-coupled small drive. The proper angle arrangement of driving-to-driven machine takes a the least space. Input and output shafts can be extended in either or both directions in horizontal or vertical plans adaptable to any installation requirement. Efficient motor speeds are decreased to slow speed requirements of several 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 surface and polished alloy steel worm develops a clean, work hardened surface on the bronze gear. Because of this worm gears use in and improve with prolonged service while additional gears are deteriorating. 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 possible housing damage from external sources (as in steel mills or mobile apparatus applications) Ever-Power 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 feasible with regular cast iron products. Extra heavy side plates connect the worm and gear shaft bearing facilitates, assuring appropriate meshing of the apparatus under all load conditions. In smaller sized sizes, fabricated steel reducers are interchangeable with Ever-Power regular cast iron reducers.
Custom Designs
Ever-Power can provide custom rate and reversed engineered reducers for the application, be it a fresh project or a primary drop-in replacement for a competitor’s velocity reducer. Fabricated steel reducers allow Ever-Power to match a competitor’s footprint, centerline, and shaft height allowing a primary drop-in replacement saving the client time and money.
Long – Quiet Life
All worm gears in Ever-Power reducers are manufactured from phosphorous bronze. Our style also incorporates a hardened, ground and polished alloy steel worm. This combination develops a soft, work-hardened mating surface of the bronze equipment which enhances with prolonged service.
Worm gearing is a class of gear reducers that utilizes correct angle, nonintersecting shafts. This style of reducer provides easy and quiet operation and permits the probability of large rate reductions. These gears are available from share in a wide variety of ratios, from only 4:1 to as much as 3600:1. The compact design and structure allows worm gear reducers to be placed in a relatively small space. Thus, high reductions in a limited package size can be achieved with this configuration. Our worm gear features the constant sliding tooth action 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 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 equipment reducer gearbox series base on years of experiences uses designed teeth surface with unsurpassed torque transfer efficiency with great performance, efficency and cost.Worm gear program transmits power through sliding contact, resulting in extremely low vibration , sound, little backlash and self-locking property
-Housing:Onetime we casting creats great rigidity for serious impacts. Outer cooling fins and inner lubrication essential oil diversion channel design to increase heat dissipation.
-Worm Shaft: Manufactured with Carbon alloyed Steel S45C or SCM415, precison machined and carburized to HRC45 or HRC60, after that 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 gear reducer is one kind of reduction gear package which includes a worm pinion input, an output worm equipment, and features a right angle output orientation. This kind of reduction gear package is normally used to have a rated motor rate and create 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 gear reducers are also a popular type of quickness reducer because they offer the greatest speed decrease in the tiniest 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 tests equipment, elevators, protection 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 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 manufactured with rugged compression-molded glass-fill up polyester housings for a durable, long lasting, light weight speed reducer that is also compact, non-corrosive, 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 much better than other decrease gearbox styles, making them well suited for demanding applications.

Worm Gear Reducers also called worm gearbox or worm rate reducers. Worm gear reducers are utilized for speed decrease and increasing the torque for electric powered electric motor drives. You can choose to mount your NEMA electric motor to the reducer utilizing the NEMA C face flange or use a coupling. If you want a coupling for the output or input shaft observe our coupling section for choosing the coupling. We offer four assemblies left hands and right hand and double result shaft and shaft input and shaft result. Interchangeable with many worm gear manufactures.

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 versions are 56C or 145TC flange mount with either right, remaining or dual output shafts or a hollow bore output. The indirect drive versions are shaft input-shaft result boxes for use with sprocket or pulley drive systems. They provide an effective low priced 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 service factor for the application form. Click on “Specifications” above for a table that will assist in identifying the service factor. For service elements above 1.0, multiply the mandatory torque by the assistance factor.
