worm gear speed reducer
Single reduction worm gearing offers high ratio reduction with couple of moving parts in a close-coupled small drive. The proper angle set up of driving-to-driven machine takes a the least space. Input and output shafts can be prolonged in either or both directions in horizontal or vertical plans adaptable to any installation requirement. Efficient electric motor speeds are decreased to sluggish speed requirements of several industrial machines in one reduction.

The exclusive usage of the involute Helicoid Thread form (with departing side contact) on the worm and gear provides for 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. Because of this worm gears use in and improve with extented service while other gears are wearing out. Ever-Power offers a wide selection of model configurations, sizes, ratios, and components from our standard products.
Fabricated Designs
If the 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 that allows the transmitting of higher horsepower levels than are possible with standard cast iron systems. Extra heavy part plates connect the worm and equipment shaft bearing facilitates, assuring appropriate meshing of the apparatus under all load conditions. In smaller sizes, fabricated steel reducers are interchangeable with Ever-Power regular cast iron reducers.
Custom Designs
Ever-Power can provide custom rate and reversed engineered reducers for your application, be it a fresh project or a primary drop-in alternative to a competitor’s rate reducer. Fabricated metal reducers enable Ever-Power to complement a competitor’s footprint, centerline, and shaft elevation allowing a direct drop-in alternative saving the client time and money.
Long – Quiet Life
All worm gears in Ever-Power reducers are produced from phosphorous bronze. Our style also incorporates a hardened, ground and polished alloy metal worm. This mixture develops a clean, work-hardened mating surface area of the bronze equipment which improves with prolonged service.
Worm gearing is a course of gear reducers that utilizes correct angle, nonintersecting shafts. This form of reducer provides soft and quiet procedure and allows for the possibility of large rate reductions. These gears are available from stock in a wide variety of ratios, from only 4:1 up to 3600:1. The small 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 equipment features the continuous sliding tooth actions between worm and one’s teeth. This escalates the tolerance for weighty loads and shock loads. Worm gear drives provide users high reducing capacity for relatively low cost when compared to various 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 utilize worm gearing are: conveyors, mixers and bucket elevators.

A worm gear reducer is one kind of reduction gear package which consists of a worm pinion input, an output worm equipment, and includes a right angle output orientation. This type of reduction gear box is normally used to have a rated motor swiftness and create a low speed result with higher torque value based on the decrease ratio. They often times can solve space-saving problems since the worm equipment reducer is among the sleekest decrease gearboxes available because of the little diameter of its output gear.
worm gear reducerWorm equipment reducers are also a popular type of speed reducer because they provide the greatest speed decrease in the tiniest package. With a higher ratio of speed decrease and high torque result 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 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, noncorrosive, and nonmetallic.
Features
Our worm gear reducers offer an option of a solid or hollow output shaft and feature an adjustable mounting position. Both SW-1 and the SW-5, nevertheless, can withstand shock loading better than other reduction gearbox styles, making them perfect for demanding applications.

Worm Gear Reducers also known as worm gearbox or worm acceleration reducers. Worm equipment reducers are used for speed reduction and increasing the torque for electric electric motor drives. You can choose to install your NEMA engine to the reducer utilizing the NEMA C face flange or make use of a coupling. If you want a coupling for the result or input shaft find 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 many worm gear manufactures.

Description
The HDR Series worm equipment reducers are used 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 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 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 mandatory torque and support factor for the application. Click on “Specifications” above for a table that will assist in identifying the service aspect. For service factors above 1.0, multiply the required torque by the service factor.
