worm gear speed reducer
One reduction worm gearing provides high ratio reduction with few shifting parts in a close-coupled small drive. The proper 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 mounting requirement. Efficient electric motor 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 life. The hardened floor and polished alloy steel worm develops a soft, work hardened surface area on the bronze gear. Because of this worm gears use in and improve with extented service while other gears are wearing out. Ever-Power offers a broad selection of model configurations, sizes, ratios, and add-ons from our standard products.
Fabricated Designs
If your application involves serious shock loads or possible housing damage from external sources (as in steel mills or mobile equipment 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 transmitting of higher horsepower levels than are feasible with standard cast iron models. Extra heavy aspect plates connect the worm and equipment shaft bearing facilitates, assuring proper meshing of the gear under all load conditions. In smaller sizes, fabricated steel reducers are interchangeable with Ever-Power regular cast iron reducers.
Custom Designs
Ever-Power can offer custom quickness and reversed engineered reducers for the application, be it a new project or a primary drop-in replacement for a competitor’s velocity reducer. Fabricated steel reducers allow Ever-Power to complement a competitor’s footprint, centerline, and shaft height allowing a primary 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 style also incorporates a hardened, ground and polished alloy steel worm. This mixture develops a easy, work-hardened mating surface of the bronze gear which increases with prolonged service.
Worm gearing is a class of equipment reducers that utilizes correct angle, nonintersecting shafts. This style of reducer provides even and quiet operation and permits the possibility of large acceleration reductions. These gears are available from stock in a wide variety of ratios, from as low as 4:1 to as much as 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 can be achieved with this configuration. Our worm equipment features the constant sliding tooth actions between worm and the teeth. This increases the tolerance for weighty loads and shock loads. Worm gear drives provide users high reducing capacity for relatively low cost in comparison with some 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 make use of worm gearing are: conveyors, mixers and bucket elevators.

A worm equipment reducer is one type of reduction gear package which contains a worm pinion insight, an output worm gear, and includes a right angle output orientation. This type of reduction gear package is generally used to take a rated motor acceleration and produce a low speed result with higher torque value based on the reduction ratio. They often times can solve space-saving problems since the worm gear reducer is among the sleekest decrease gearboxes available due to the little diameter of its output gear.
worm gear reducerWorm equipment reducers are also a favorite type of speed reducer because they offer the greatest speed decrease in the smallest package. With a higher 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 testing equipment, elevators, security 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 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 produced with durable compression-molded glass-fill polyester housings for a long lasting, long lasting, light weight speed reducer that is also compact, non-corrosive, and nonmetallic.
Features
Our worm equipment reducers offer a choice of a good or hollow result shaft and feature an adjustable mounting position. Both the SW-1 and the SW-5, however, can endure shock loading much better than other reduction gearbox styles, making them well suited for demanding applications.

Worm Equipment Reducers also referred to as worm gearbox or worm rate reducers. Worm gear reducers are utilized for speed reduction and increasing the torque for electric powered motor drives. You can decide to mount your NEMA engine to the reducer by using the NEMA C encounter flange or make use of a coupling. If you want a coupling for the output or input shaft find our coupling section for selecting a coupling. You can expect four assemblies left hand and right hand and double output shaft and shaft input and shaft result. Interchangeable with many worm gear manufactures. See data sheet in product overview for diamensions. If you don’t see your type, make sure you Contact Us.

Description
The HDR Series worm gear reducers are used in low to moderate horsepower applications to lessen speeds and increase torque. Worm gear reducers are available 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 versions are shaft input-shaft result boxes for make use of with sprocket or pulley drive systems. They provide an effective low cost solution to speed decrease and increased torque, with higher tolerances for shock loading than helical gear reducers.
In order to decide on a gearbox speed reducer, you will need to determine the mandatory torque and service factor for the application. Click on “Specs” above for a table that will aid in determining the service aspect. For service factors above 1.0, multiply the mandatory torque by the support factor.
