worm gear speed reducer
Solitary reduction worm gearing provides high ratio reduction with couple of shifting parts in a close-coupled compact drive. The right angle arrangement 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 engine speeds are decreased to slow speed requirements of many industrial machines in a single reduction.

The exclusive usage of the involute Helicoid Thread form (with leaving side contact) on the worm and gear provides for high efficiencies, and lengthy service lifestyle. The hardened floor and polished alloy metal worm develops a smooth, work hardened surface 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 selection of model configurations, sizes, ratios, and components from our standard product line.
Fabricated Designs
If the 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 transmitting of higher horsepower levels than are possible with regular cast iron systems. Extra heavy aspect plates connect the worm and gear shaft bearing facilitates, assuring appropriate 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 speed and reversed engineered reducers for the application, be it a fresh project or a primary drop-in alternative to a competitor’s swiftness reducer. Fabricated steel reducers enable Ever-Power to complement a competitor’s footprint, centerline, and shaft elevation allowing a direct drop-in alternative saving the client time and money.
Long – Quiet Life
All worm gears in Ever-Power reducers are produced from phosphorous bronze. Our style also incorporates a hardened, surface and polished alloy metal worm. This combination develops a smooth, work-hardened mating surface area of the bronze equipment which increases with prolonged service.
Worm gearing is a course of equipment reducers that utilizes correct angle, nonintersecting shafts. This style of reducer provides simple and quiet procedure and allows for the probability of large quickness reductions. These gears are available from stock in a wide selection of ratios, from as low as 4:1 up to 3600:1. The compact design and structure allows worm equipment reducers to be positioned in a comparatively small space. Thus, high reductions in a restricted package size may be accomplished with this configuration. Our worm gear features the constant sliding tooth action between worm and the teeth. This increases 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.

-Housing:Onetime we casting creats great rigidity for serious impacts. Outer cooling fins and inner lubrication essential 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 contains a worm pinion input, an output worm gear, and features a right angle result orientation. This type of reduction gear box is normally used to take a rated motor velocity and create a low speed result with higher torque worth based on the reduction ratio. They often times can solve space-saving problems since the worm equipment reducer is among the sleekest decrease gearboxes available because of the little diameter of its output gear.
worm gear reducerWorm gear reducers are also a favorite type of quickness reducer because they offer the greatest speed reduction in the tiniest package. With a higher ratio of speed reduction and high torque result multiplier, it’s unsurprising that many power transmission systems utilize a worm equipment reducer. Some of the most common 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 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 tough 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 gear reducers offer an option of a solid or hollow result shaft and feature an adjustable mounting placement. Both SW-1 and the SW-5, nevertheless, can withstand shock loading better than other reduction gearbox designs, making them perfect for demanding applications.

Worm Gear Reducers also known as worm gearbox or worm speed reducers. Worm equipment reducers are used for speed reduction and increasing the torque for electrical motor drives. You can choose to mount your NEMA electric motor to the reducer by using the NEMA C encounter flange or make use of a coupling. If you need a coupling for the result or input shaft see our coupling section for choosing the coupling. We offer four assemblies left hands 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 gear reducers are used 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, left or dual output 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 increased torque, with higher tolerances for shock loading than helical equipment reducers.
In order to select a gearbox speed reducer, you will have to determine the required torque and program factor for the application. Click on “Specifications” above for a desk that will aid in identifying the service aspect. For service factors above 1.0, multiply the required torque by the program factor.
