One reduction worm gearing provides high ratio reduction with couple of moving parts in a close-coupled compact drive. The proper angle set up of driving-to-driven machine requires a the least space. Input and output shafts can be prolonged in either or both directions in horizontal or vertical plans adaptable to any mounting requirement. Efficient engine speeds are decreased to sluggish speed requirements of several industrial machines in one reduction.

The exclusive usage of the involute Helicoid Thread form (with leaving side contact) on the worm and gear provides for high efficiencies, and long service existence. The hardened floor and polished alloy steel worm develops a even, work hardened surface on the bronze gear. Because of this worm gears put on in and improve with prolonged service while various other gears are wearing out. Ever-Power offers a wide collection of model configurations, sizes, ratios, and components from our standard product line.
Fabricated Designs
If the application involves severe shock loads or possible housing damage from external sources (as in steel mills or mobile tools applications) Ever-Power can provide fabricated steel housings with up to 48″ center distances. Fabricated housings provide optimum rigidity and strength which allows the tranny of higher horsepower levels than are possible with regular cast iron models. Extra heavy part plates connect the worm and gear shaft bearing facilitates, assuring correct meshing of the gear under all load circumstances. In smaller sizes, fabricated metal 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 new project or a primary drop-in replacement for a competitor’s rate reducer. Fabricated steel reducers enable Ever-Power to complement a competitor’s footprint, centerline, and shaft elevation allowing a primary drop-in replacement saving the customer time and money.
Long – Quiet Life
All worm gears in Ever-Power reducers are manufactured from phosphorous bronze. Our style also includes a hardened, surface and polished alloy metal worm. This mixture develops a clean, work-hardened mating surface of the bronze equipment which improves with prolonged service.
Worm gearing is a class of gear reducers that utilizes correct angle, nonintersecting shafts. This form of reducer provides even and quiet procedure and allows for the probability of large rate reductions. These gears are available from share in a wide selection of ratios, from as low as 4:1 up to 3600:1. The small design and construction allows worm equipment reducers to be positioned in a comparatively small space. Thus, very high reductions in a limited package size may be accomplished with this configuration. Our worm gear features the continuous sliding tooth actions between worm and the teeth. This escalates the tolerance for heavy loads and shock loads. Worm gear drives provide users high reducing capacity for relatively low cost in comparison with various 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.

A worm equipment reducer is one kind of reduction gear container which contains a worm pinion insight, an output worm equipment, and includes a right angle result orientation. This type of reduction gear container is normally used to take a rated motor quickness and create a low speed result with higher torque value based on the decrease ratio. They often can solve space-saving problems because the worm equipment reducer is one of the sleekest decrease gearboxes available because of the small diameter of its output gear.
worm gear reducerWorm equipment reducers are also a favorite type of swiftness reducer because they provide the greatest speed reduction in the smallest 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 are available in tuning instruments, medical examining equipment, elevators, protection 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 range 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 produced with durable 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 an option of a good or hollow output shaft and show an adjustable mounting position. Both the SW-1 and the SW-5, nevertheless, can endure shock loading much better than other reduction gearbox designs, making them ideal for demanding applications.

Worm Equipment Reducers also referred to as worm gearbox or worm quickness reducers. Worm equipment reducers are used for speed decrease and increasing the torque for electric motor drives. You can choose to attach your NEMA motor to the reducer utilizing the NEMA C face flange or use a coupling. If you need a coupling for the output or input shaft observe 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 used 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 attach with either right, still left or dual output shafts or a hollow bore output. 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 equipment reducers.
In order to select a gearbox speed reducer, you will have to determine the required torque and service factor for the application form. Click on “Specs” above for a desk that will aid in determining the service element. For service factors above 1.0, multiply the required torque by the program factor.
