worm gear speed reducer

Solitary reduction worm gearing provides high ratio reduction with few shifting parts in a close-coupled small drive. The proper angle set up 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 plans adaptable to any mounting requirement. Efficient motor speeds are reduced to gradual speed requirements of many industrial machines in one reduction.

The exclusive utilization of the involute Helicoid Thread form (with leaving side contact) on the worm and gear offers high efficiencies, and long service lifestyle. The hardened surface and polished alloy steel worm develops a clean, work hardened surface area on the bronze gear. For this reason worm gears use in and improve with extented service while other gears are deteriorating. Ever-Power offers a wide selection of model configurations, sizes, ratios, and add-ons from our standard products.
Fabricated Designs
If the application involves severe shock loads or possible housing damage from external sources (as in steel mills or mobile products applications) Ever-Power can provide fabricated steel housings with up to a 48″ center distances. Fabricated housings provide optimum rigidity and strength which allows the tranny of higher horsepower levels than are feasible with regular cast iron units. Extra heavy part plates connect the worm and gear shaft bearing facilitates, assuring correct meshing of the gear under all load conditions. In smaller sized sizes, fabricated steel worm gear speed reducer reducers are interchangeable with Ever-Power regular cast iron reducers.
Custom Designs
Ever-Power can offer custom rate and reversed engineered reducers for your application, be it a fresh project or a primary drop-in alternative to a competitor’s quickness reducer. Fabricated steel reducers allow Ever-Power to complement a competitor’s footprint, centerline, and shaft elevation allowing a primary drop-in substitute saving the client time and money.
Long – Quiet Life
All worm gears in Ever-Power reducers are produced from phosphorous bronze. Our design also incorporates a hardened, floor and polished alloy steel worm. This combination develops a clean, work-hardened mating surface area of the bronze equipment which increases with prolonged service.
Worm gearing is a course of gear reducers that utilizes right angle, nonintersecting shafts. This style of reducer provides even and quiet procedure and permits the possibility of large acceleration reductions. These gears can be found from share in a wide selection of ratios, from only 4:1 up to 3600:1. The compact design and building allows worm equipment reducers to be placed in a relatively small space. Thus, high reductions in a limited package size may be accomplished with this configuration. Our worm gear features the constant sliding tooth action between worm and one’s teeth. This escalates the tolerance for large loads and shock loads. Worm gear drives offer users high reducing convenience of relatively low cost when compared to various 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 utilize worm gearing are: conveyors, mixers and bucket elevators.

A worm equipment reducer is one kind of reduction gear container which consists of a worm pinion insight, an output worm equipment, and features a right angle result orientation. This kind of reduction gear container is generally used to have a rated motor rate and produce a low speed result with higher torque worth based on the reduction ratio. They often times can resolve space-saving problems because the worm gear 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 speed reducer because they provide the greatest speed reduction in the tiniest package. With a higher ratio of speed reduction and high torque result multiplier, it’s unsurprising that lots of power transmission systems utilize a worm gear reducer. Some of the most common applications for worm gears can be found in tuning instruments, medical testing equipment, elevators, security 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 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 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 good or hollow result shaft and show an adjustable mounting position. Both the SW-1 and the SW-5, however, can withstand shock loading better than other decrease gearbox styles, making them well suited for demanding applications.

Worm Equipment Reducers also known as worm gearbox or worm speed reducers. Worm gear reducers are used for speed decrease and increasing the torque for electrical engine drives. You can choose to mount your NEMA engine to the reducer by using the NEMA C face flange or use a coupling. If you want a coupling for the output or input shaft see our coupling section for choosing the coupling. You can expect four assemblies left hand and right hands and double result shaft and shaft input and shaft result. Interchangeable with most 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 can be found in direct or indirect drive, direct drive versions are 56C or 145TC flange mount with either right, remaining 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 provide an effective low priced 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 have to determine the required torque and service factor for the application. Click on “Specs” above for a table that will aid in determining the service element. For service factors above 1.0, multiply the mandatory torque by the program factor.
