worm gear speed reducer
One reduction worm gearing provides high ratio reduction with few moving parts in a close-coupled compact drive. The proper angle set up of driving-to-driven machine takes a the least space. Input and result shafts can be extended in either or both directions in horizontal or vertical plans adaptable to any installation requirement. Efficient motor speeds are decreased to slower speed requirements of several industrial machines in a single reduction.

The exclusive use of the involute Helicoid Thread form (with departing side contact) on the worm and gear provides for high efficiencies, and long service lifestyle. The hardened floor and polished alloy metal worm develops a simple, work hardened surface area on the bronze equipment. For this reason worm gears use in and improve with extented service while additional gears are wearing out. Ever-Power offers a wide 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 devices applications) Ever-Power can offer fabricated steel housings with up to 48″ center distances. Fabricated housings provide optimum rigidity and strength that allows the transmitting of higher horsepower amounts than are possible with standard cast iron models. Extra heavy side plates connect the worm and gear shaft bearing supports, assuring correct 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 offer custom speed and reversed engineered reducers for your application, be it a new project or a direct drop-in alternative to a competitor’s swiftness reducer. Fabricated steel reducers allow Ever-Power to complement a competitor’s footprint, centerline, and shaft height allowing a primary drop-in replacement 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, surface and polished alloy metal worm. This mixture develops a even, work-hardened mating surface of the bronze equipment which enhances with prolonged service.
Worm gearing is a course of equipment reducers that utilizes right angle, nonintersecting shafts. This style of reducer provides even and quiet operation 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 building allows worm equipment reducers to be placed in a comparatively small space. Thus, high reductions in a restricted package size may be accomplished with this configuration. Our worm gear features the continuous sliding tooth action between worm and one’s teeth. This increases the tolerance for heavy loads and shock loads. Worm gear drives provide users high reducing capacity for relatively low cost in comparison with 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 gear reducer is one kind of reduction gear container which contains a worm pinion input, an output worm gear, and features a right angle output orientation. This kind of reduction gear container is normally used to have a rated motor speed and produce a low speed result with higher torque value based on the reduction ratio. They often times can resolve space-saving problems because the worm gear reducer is one of the sleekest decrease gearboxes available due to the little diameter of its result gear.
worm gear reducerWorm gear reducers are also a favorite type of velocity reducer because they offer the greatest speed reduction in the tiniest package. With a high ratio of speed reduction and high torque output multiplier, it’s unsurprising that lots of power transmission systems utilize a worm equipment reducer. Some of the most common applications for worm gears are available in tuning instruments, medical assessment 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 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 these options are produced with rugged compression-molded glass-fill polyester housings for a long lasting, long lasting, light-weight speed reducer that is also compact, noncorrosive, and nonmetallic.
Features
Our worm equipment reducers offer an option of a good or hollow output shaft and show an adjustable mounting placement. Both SW-1 and the SW-5, nevertheless, can withstand shock loading better than other reduction gearbox styles, making them ideal for demanding applications.

Worm Equipment Reducers also called worm gearbox or worm acceleration reducers. Worm equipment reducers are used for speed reduction and raising the 
torque for electrical engine drives. You can decide to attach your NEMA engine to the reducer utilizing the NEMA C encounter 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 output shaft and shaft insight and shaft output. Interchangeable with the majority of 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 can be found in direct or indirect drive, direct drive versions are 56C or 145TC flange install with either right, still left or dual result shafts or a hollow bore result. 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 cost solution to speed reduction 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 services factor for the application form. Click on “Specifications” above for a desk that will aid in identifying the service aspect. For service elements above 1.0, multiply the required torque by the service factor.
