worm gear speed reducer
One reduction worm gearing provides high ratio reduction with few moving parts in a close-coupled small drive. The right angle arrangement of driving-to-driven machine takes a the least space. Input and output shafts can be extended in either or both directions in horizontal or vertical arrangements adaptable to any mounting requirement. Efficient electric motor speeds are decreased to slow speed requirements of several industrial machines in a single reduction.

The exclusive utilization 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 floor and polished alloy metal worm develops a even, work hardened surface area on the bronze equipment. Because of this worm gears use in and improve with prolonged service while additional gears are wearing out. Ever-Power offers a broad collection of model configurations, sizes, ratios, and accessories 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 devices 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 transmitting of higher horsepower amounts than are feasible with regular cast iron products. Extra heavy part plates connect the worm and gear shaft bearing supports, assuring proper meshing of the apparatus under all load conditions. In smaller sized sizes, fabricated metal reducers are interchangeable with Ever-Power regular cast iron reducers.
Custom Designs
Ever-Power can offer custom speed and reversed engineered reducers for the application, be it a new project or a primary drop-in alternative to a competitor's acceleration reducer. Fabricated metal reducers enable Ever-Power to complement a competitor's footprint, centerline, and shaft elevation allowing a direct drop-in substitute saving the client time and money.
Long – Quiet Life
All worm gears in Ever-Power reducers are manufactured from phosphorous bronze. Our design also includes a hardened, ground and polished alloy steel worm. This mixture develops a easy, work-hardened mating surface area of the bronze gear which enhances 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 allows for the likelihood of large velocity reductions. These gears are available from stock in a wide variety of ratios, from only 4:1 up to 3600:1. The compact design and construction allows worm gear reducers to be positioned in a comparatively small space. Thus, very high reductions in a limited package size may be accomplished with this configuration. Our worm gear features the continuous 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 convenience of 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 type of reduction gear package which includes a worm pinion insight, an output worm equipment, and includes a right angle result orientation. This kind of reduction gear box is normally used to have a rated motor quickness and produce a low speed output with higher torque worth based on the reduction ratio. They often times can solve space-saving problems because the worm gear reducer is among the sleekest reduction gearboxes available because of the small diameter of its output gear.
worm gear reducerWorm equipment reducers are also a favorite type of rate reducer because they offer the greatest speed reduction in the smallest package. With a higher ratio of speed decrease and high torque output multiplier, it's unsurprising that many power transmission systems make use of a worm gear reducer. Some of the most common applications for worm gears can be found in tuning instruments, medical assessment 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 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 of these options are manufactured with rugged compression-molded glass-fill polyester housings for a long lasting, long lasting, light-weight speed reducer that's also compact, non-corrosive, and nonmetallic.
Features
Our worm gear reducers offer an option of a good or hollow output shaft and feature an adjustable mounting position. Both the SW-1 and the SW-5, however, can withstand shock loading much better than other decrease gearbox designs, making them perfect for demanding applications.

Worm Equipment Reducers also known as worm gearbox or worm swiftness reducers. Worm gear reducers are utilized for speed reduction and increasing the torque for electric engine drives. You can choose to attach your NEMA engine to the reducer utilizing the NEMA C encounter flange or make use of a coupling. If you want a coupling for the output or input shaft observe our coupling section for choosing the coupling. You can expect four assemblies left hands and right hand and double output shaft and shaft insight and shaft result. Interchangeable with the majority of worm gear manufactures. Observe data sheet in item overview for diamensions. If you don't see your type, make sure you Contact Us.

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 versions are 56C or 145TC flange attach with either right, still left or dual result shafts or a hollow bore result. The indirect drive versions are shaft input-shaft result boxes for use with sprocket or pulley drive systems. They provide an effective low cost solution to speed decrease and improved 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 form. Click on “Specifications” above for a table that will assist in determining the service aspect. For service elements above 1.0, multiply the mandatory torque by the assistance factor.
