worm gear speed reducer

Solitary reduction worm gearing provides high ratio reduction with couple of shifting parts in a close-coupled small drive. The proper angle arrangement of driving-to-driven machine requires a minimum of space. Input and result shafts can be prolonged in either or both directions in horizontal or vertical arrangements adaptable to any installation requirement. Efficient motor speeds are decreased to slow speed requirements of several industrial machines in a single reduction.

The exclusive use of the involute Helicoid Thread form (with departing side contact) on the worm and gear offers high efficiencies, and lengthy service existence. The hardened surface and polished alloy steel worm develops a easy, work hardened surface on the bronze equipment. For this reason worm gears wear in and improve with extented service while additional gears are deteriorating. Ever-Power offers a wide collection of model configurations, sizes, ratios, and add-ons from our standard product line.
Fabricated Designs
If the application involves serious shock loads or feasible housing damage from external sources (as in steel mills or mobile apparatus applications) Ever-Power can offer fabricated steel housings with up to 48″ center distances. Fabricated housings provide optimum rigidity and strength which allows the transmitting of higher horsepower amounts than are possible with standard cast iron products. Extra heavy side plates connect the worm and gear shaft bearing facilitates, assuring proper meshing of the apparatus under all load conditions. In smaller sizes, fabricated metal reducers are interchangeable with Ever-Power regular cast iron reducers.
Custom Designs
Ever-Power can offer custom acceleration and reversed engineered reducers for the application, be it a fresh project or a direct drop-in alternative to a competitor’s speed reducer. Fabricated steel reducers allow Ever-Power to match a competitor’s footprint, centerline, and shaft height 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 incorporates a hardened, ground and polished alloy steel worm. This mixture develops a smooth, work-hardened mating surface of the bronze gear which improves with prolonged service.
Worm gearing is a course of equipment reducers that utilizes correct angle, nonintersecting shafts. This form of reducer provides even and quiet procedure and permits the likelihood of large velocity reductions. These gears can be found from share in a wide selection of ratios, from only 4:1 up to 3600:1. The small design and construction allows worm equipment reducers to be placed in a relatively small space. Thus, high reductions in a restricted package size can be achieved 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 provide users high reducing capacity for 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.

A worm equipment reducer is one kind of reduction gear package which includes a worm pinion input, an output worm gear, and includes a right angle result orientation. This type of reduction gear box is generally used to take a rated motor velocity and produce a low speed result with higher torque worth based on the reduction ratio. They often times can resolve space-saving problems since the worm gear reducer is one of the sleekest reduction gearboxes available due to the little diameter of its result gear.
worm gear reducerWorm equipment reducers are also a popular type of speed 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 many power transmission systems make use of a worm equipment reducer. Some of the most typical 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 offers 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 rugged compression-molded glass-fill polyester housings for a durable, long lasting, light-weight speed reducer that is also compact, noncorrosive, and nonmetallic.
Features
Our worm gear reducers offer a choice of a good or hollow result 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 well suited for demanding applications.

Worm Gear Reducers also referred to as worm gearbox or worm quickness reducers. Worm equipment reducers are used for speed reduction and increasing the torque for electric engine 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 observe our coupling section for selecting a coupling. You can expect four assemblies left hand and right hands and double result shaft and shaft input and shaft output. Interchangeable with the majority of worm gear manufactures.

Description
The HDR Series worm equipment reducers are found 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 versions are 56C or 145TC flange attach with either right, left or dual output shafts or a hollow bore result. The indirect drive models 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 equipment reducers.
In order to select a gearbox speed reducer, you will have to determine the mandatory torque and assistance factor for the application form. Click on “Specifications” above for a desk that will aid in determining the service aspect. For service elements above 1.0, multiply the required torque by the service factor.
