worm gear speed reducer

worm gear speed reducer
Solitary reduction worm gearing offers high ratio reduction with few 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 plans adaptable to any installation requirement. Efficient electric motor speeds are reduced to slower speed requirements of several industrial machines in a single reduction.

The exclusive usage of the involute Helicoid Thread form (with departing side contact) on the worm and gear provides for high efficiencies, and lengthy service life. The hardened ground and polished alloy metal worm develops a clean, work hardened surface area on the bronze equipment. Because of this worm gears wear in and improve with extented service while various other gears are deteriorating. Ever-Power offers a wide collection of model configurations, sizes, ratios, and add-ons 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 gear 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 amounts than are feasible with standard cast iron models. Extra heavy aspect plates connect the worm and gear shaft bearing supports, assuring appropriate meshing of the gear under all load circumstances. In smaller sizes, fabricated steel reducers are interchangeable with Ever-Power standard cast iron reducers.
Custom Designs
Ever-Power can provide custom acceleration and reversed engineered reducers for the application, be it a fresh project or a direct drop-in alternative to a competitor’s swiftness reducer. Fabricated steel reducers allow Ever-Power to match a competitor’s footprint, centerline, and shaft elevation allowing a direct drop-in substitute 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, floor and polished alloy metal worm. This combination develops a easy, work-hardened mating surface of the bronze equipment which improves with prolonged service.
Worm gearing is a course of equipment reducers that utilizes right angle, nonintersecting shafts. This style of reducer provides soft and quiet operation and permits the possibility of large acceleration reductions. These gears can be found from stock in a wide selection of ratios, from as low as 4:1 to as much as 3600:1. The compact design and construction allows worm gear reducers to be placed in a relatively small space. Thus, very high reductions in a limited package size may be accomplished with this configuration. Our worm equipment features the continuous sliding tooth action between worm and the teeth. This escalates the tolerance for heavy loads and shock loads. Worm gear drives provide users high reducing convenience of relatively low cost in comparison with some other types of gearing.
The use 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 foundation on years of experiences uses designed teeth surface with unsurpassed torque transfer performance 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: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 Steel 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 gear reducer is one type of reduction gear package which consists of a worm pinion input, an output worm gear, and includes a right angle output orientation. This type of reduction gear container is normally used to take a rated motor acceleration and create a low speed output with higher torque worth based on the reduction ratio. They often times can solve space-saving problems because the worm gear reducer is one of the sleekest reduction gearboxes available due to the small diameter of its result gear.
worm gear reducerWorm gear reducers are also a favorite type of swiftness reducer because they provide the greatest speed decrease in the smallest package. With a high ratio of speed decrease and high torque result 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 are available 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 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 is also compact, noncorrosive, and nonmetallic.
Features
Our worm gear reducers offer an option of a solid or hollow output shaft and show an adjustable mounting position. Both SW-1 and the SW-5, however, can endure shock loading much better than other decrease gearbox designs, making them well suited for demanding applications.

Worm Equipment Reducers also referred to as worm gearbox or worm acceleration reducers. Worm equipment reducers are used for speed reduction and raising the torque for electric powered motor drives. You can choose to mount your NEMA engine to the reducer by using the NEMA C face flange or make use of a coupling. If you want a coupling for the output or input shaft observe our coupling section for choosing the coupling. You can expect four assemblies left hand and right hands and double output shaft and shaft input and shaft output. Interchangeable with most worm gear manufactures. Observe data sheet in item overview for diamensions. If you don’t see your type, please Contact Us.

Description
The HDR Series worm equipment reducers are used 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 install with either right, remaining or dual result shafts or a hollow bore result. The indirect drive versions are shaft input-shaft output boxes for make use of with sprocket or pulley drive systems. They offer 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. Click on “Specifications” above for a desk that will assist in determining the service factor. For service elements above 1.0, multiply the mandatory torque by the support factor.
