worm gear speed reducer
One reduction worm gearing offers high ratio reduction with couple of moving parts in a close-coupled compact drive. The right angle arrangement of driving-to-driven machine requires a the least space. Input and result shafts can be prolonged in either or both directions in horizontal or vertical arrangements adaptable to any mounting requirement. Efficient engine speeds are reduced to slower speed requirements of many industrial machines in a single reduction.

The exclusive utilization of the involute Helicoid Thread form (with departing 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 equipment. Because of this 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 components from our standard product line.
Fabricated Designs
If your application involves serious shock loads or possible housing damage from external sources (as in steel mills or mobile gear applications) Ever-Power can offer fabricated steel housings with up to a 48″ center distances. Fabricated housings provide maximum rigidity and strength which allows the transmission of higher horsepower levels than are possible with standard cast iron systems. 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 velocity and reversed engineered reducers for your application, be it a new project or a direct drop-in replacement for a competitor’s swiftness reducer. Fabricated steel reducers enable Ever-Power to complement a competitor’s footprint, centerline, and shaft elevation allowing a primary drop-in substitute saving the customer time and money.
Long – Quiet Life
All worm gears in Ever-Power reducers are produced from phosphorous bronze. Our style also includes a hardened, ground and polished alloy metal worm. This mixture develops a simple, work-hardened mating surface of the bronze equipment which increases with prolonged service.
Worm gearing is a course of equipment reducers that utilizes right angle, nonintersecting shafts. This style of reducer provides clean and quiet operation and allows for the possibility of large speed reductions. These gears are available from share in a wide variety of ratios, from as low as 4:1 to as much as 3600:1. The compact design and building allows worm gear reducers to be positioned in a relatively small space. Thus, high reductions in a restricted package size can be achieved with this configuration. Our worm gear features the constant sliding tooth action between worm and the teeth. This escalates the tolerance for large loads and shock loads. Worm gear drives offer users high reducing capacity for relatively low cost when compared to 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 make use of worm gearing are: conveyors, mixers and bucket elevators.

A worm equipment reducer is one kind of reduction gear package which consists of a worm pinion insight, an output worm equipment, and features a right angle result orientation. This kind of reduction gear box is normally used to have a rated motor swiftness and create a low speed result with higher torque worth based on the reduction ratio. They often can resolve space-saving problems because the worm gear reducer is one of the sleekest decrease gearboxes available because of the little diameter of its result gear.
worm gear reducerWorm gear reducers are also a popular type of velocity reducer because they provide the greatest speed decrease in the tiniest package. With a high ratio of speed decrease and high torque result multiplier, it’s unsurprising that lots of power transmission systems utilize a worm equipment reducer. Some of the most typical applications for worm gears can be found in tuning instruments, medical screening equipment, elevators, protection gates, and conveyor belts.
SW-1 and SW-5
Torque Transmission provides 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 these options are manufactured with durable compression-molded glass-fill polyester housings for a long lasting, long lasting, light-weight speed reducer that’s also compact, noncorrosive, and nonmetallic.
Features
Our worm equipment reducers offer an option of a good or hollow result shaft and feature an adjustable mounting position. Both the SW-1 and the SW-5, nevertheless, can endure shock loading 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 gear reducers are used for speed reduction and raising the torque for electric powered electric motor drives. You can decide to install your NEMA engine to the reducer utilizing the NEMA C encounter flange or use a coupling. If you want a coupling for the result or input shaft find our coupling section for choosing the coupling. You can expect four assemblies left hands and right hand and double result shaft and shaft input and shaft output. Interchangeable with many worm gear manufactures.

Description
The HDR Series worm equipment 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 mount with either right, left or dual result shafts or a hollow bore result. The indirect drive versions are shaft input-shaft output 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 select a gearbox speed reducer, you will need to determine the mandatory torque and support factor for the application. Click on “Specifications” above for a table that will assist in determining the service factor. For service factors above 1.0, multiply the required torque by the service factor.
