worm gear speed reducer

Single reduction worm gearing offers high ratio reduction with few shifting 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 plans adaptable to any mounting requirement. Efficient motor speeds are reduced to slower speed requirements of several industrial machines in one reduction.

The exclusive use of the involute Helicoid Thread form (with departing side contact) on the worm and gear offers high efficiencies, and long service lifestyle. The hardened floor and polished alloy steel worm develops a simple, work hardened surface area on the bronze equipment. Because of this worm gears put on in and worm gear speed reducer improve with prolonged service while additional 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 tools applications) Ever-Power can offer fabricated steel housings with up to a 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 units. Extra heavy part plates connect the worm and gear shaft bearing facilitates, assuring proper meshing of the gear 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 acceleration 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 elevation allowing a primary 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 design also incorporates a hardened, surface and polished alloy metal worm. This mixture develops a simple, 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 acceleration reductions. These gears can be found 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 equipment reducers to be positioned 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 action between worm and the teeth. This escalates the tolerance for large loads and shock loads. Worm gear drives offer users high reducing capacity for relatively low cost when compared to some 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.
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 cost.Worm gear program transmits power through sliding contact, resulting in extremely low vibration , sound, little backlash and self-locking property
-Housing:One time we casting creats great rigidity for severe impacts. Outer cooling fins and internal lubrication oil diversion channel design to improve heat dissipation.
-Worm Shaft: Manufactured with Carbon alloyed Metal S45C or SCM415, precison machined and carburized to HRC45 or HRC60, after that for precision tooth grinding to make sure 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 gear, and includes a right angle result orientation. This kind of reduction gear package is generally used to take a rated motor rate and produce a low speed output with higher torque value based on the reduction ratio. They often times can solve space-saving problems since 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 favorite type of quickness reducer because they offer the greatest speed decrease in the smallest package. With a high ratio of speed reduction and high torque output multiplier, it’s unsurprising that lots of power transmission systems make use of a worm gear reducer. Some of the most typical applications for worm gears can be found in tuning instruments, medical assessment 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 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 manufactured with durable compression-molded glass-fill up polyester housings for a durable, long lasting, light weight speed reducer that’s also compact, noncorrosive, 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, however, can withstand shock loading much better than other reduction gearbox designs, making them perfect for demanding applications.

Worm Gear Reducers also called worm gearbox or worm speed reducers. Worm equipment reducers are utilized for speed reduction and increasing the torque for electrical engine drives. You can choose to attach your NEMA engine to the reducer by using the NEMA C face 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 hand and double result shaft and shaft input and shaft result. Interchangeable with most worm gear manufactures.

Description
The HDR Series worm equipment reducers are found 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 versions are 56C or 145TC flange attach with either right, still left or dual result shafts or a hollow bore result. 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 form. Click on “Specifications” above for a table that will aid in identifying the service factor. For service elements above 1.0, multiply the required torque by the support factor.
