One reduction worm gearing provides high ratio reduction with few moving parts in a close-coupled compact drive. The proper angle arrangement of driving-to-driven machine requires a minimum of space. Input and output shafts can be extended in either or both directions in horizontal or vertical arrangements adaptable to any installation requirement. Efficient electric motor speeds are reduced 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 offers high efficiencies, and long service life. The hardened ground and polished alloy steel worm develops a smooth, work hardened surface area on the bronze gear. For this reason worm gears put on in and improve with extented service while various other gears are wearing out. Ever-Power offers a wide selection of model configurations, sizes, ratios, and add-ons 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 provide fabricated steel housings with up to a 48″ center distances. Fabricated housings provide optimum rigidity and strength that allows the transmitting of higher horsepower levels than are possible with standard cast iron models. Extra heavy side plates connect the worm and gear shaft bearing supports, assuring proper meshing of the apparatus under all load conditions. In smaller sizes, fabricated steel 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 new project or a primary drop-in alternative to a competitor’s rate reducer. Fabricated steel reducers enable Ever-Power to match a competitor’s footprint, centerline, and shaft height allowing a direct drop-in alternative saving the customer time and money.
Long – Quiet Life
All worm gears in Ever-Power reducers are manufactured from phosphorous bronze. Our design also incorporates a hardened, floor and polished alloy metal worm. This combination develops a soft, work-hardened mating surface area of the bronze equipment which increases with prolonged service.
Worm gearing is a class of equipment reducers that utilizes right angle, nonintersecting shafts. This style of reducer provides easy and quiet procedure and allows for the likelihood of large acceleration reductions. These gears can be found from share in a wide selection of ratios, from as low as 4:1 to as much as 3600:1. The compact design and structure allows worm equipment reducers to be placed in a relatively small space. Thus, very high reductions in a restricted package size may be accomplished with this configuration. Our worm equipment 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 in comparison with various 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 utilize worm gearing are: conveyors, mixers and bucket elevators.

A worm gear reducer is one type of reduction gear package which consists of a worm pinion input, an output worm equipment, and features a right angle result orientation. This type of reduction gear package is normally used to have a rated motor acceleration and produce a low speed result 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 because of the small diameter of its output gear.
worm gear reducerWorm gear reducers are also a favorite type of rate reducer because they provide the greatest speed reduction in the tiniest package. With a high ratio of speed reduction and high torque output multiplier, it’s unsurprising that many power transmission systems utilize a worm equipment reducer. Some of the most typical 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 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 produced with tough compression-molded glass-fill up polyester housings for a long lasting, long lasting, light weight speed reducer that’s also compact, non-corrosive, and nonmetallic.
Features
Our worm gear reducers offer a choice of a good or hollow output shaft and show an adjustable mounting placement. Both the 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 called worm gearbox or worm quickness reducers. Worm equipment reducers are utilized for speed reduction and raising the torque for electric powered electric motor drives. You can choose to mount your NEMA engine to the reducer utilizing the NEMA C face flange or use a coupling. If you need a coupling for the output or input shaft find our coupling section for selecting a coupling. We offer four assemblies left hand and right hand and double result shaft and shaft insight and shaft output. Interchangeable with the majority of 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 models are 56C or 145TC flange attach with either right, left or dual result shafts or a hollow bore output. The indirect drive models are shaft input-shaft result boxes for make use of with sprocket or pulley drive systems. They offer an effective low cost solution to speed reduction and increased torque, with higher tolerances for shock loading than helical equipment reducers.
In order to decide on a gearbox speed reducer, you will need to determine the required torque and assistance factor for the application form. Click on “Specs” above for a table that will aid in identifying the service aspect. For service factors above 1.0, multiply the required torque by the support factor.
