Single reduction worm gearing provides high ratio reduction with couple of moving parts in a close-coupled small drive. The right angle set up of driving-to-driven machine takes a minimum of space. Input and result shafts can be extended in either or both directions in horizontal or vertical plans adaptable to any mounting requirement. Efficient motor speeds are decreased to slow speed requirements of several industrial machines in one reduction.

The exclusive usage of the involute Helicoid Thread form (with leaving side contact) on the worm and gear offers high efficiencies, and long service existence. The hardened surface and polished alloy metal worm develops a clean, work hardened surface on the bronze gear. Because of this worm gears put on in and improve with extented service while additional gears are wearing out. Ever-Power offers a wide selection of model configurations, sizes, ratios, and accessories from our standard product line.
Fabricated Designs
If the worm gear speed reducer 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 maximum rigidity and strength which allows the tranny of higher horsepower levels than are feasible with regular cast iron systems. Extra heavy part plates connect the worm and gear shaft bearing supports, assuring appropriate meshing of the gear under all load conditions. In smaller sized sizes, fabricated steel reducers are interchangeable with Ever-Power standard cast iron reducers.
Custom Designs
Ever-Power can provide custom quickness and reversed engineered reducers for the application, be it a new project or a primary drop-in alternative to a competitor’s rate reducer. Fabricated metal reducers allow Ever-Power to complement a competitor’s footprint, centerline, and shaft height allowing a primary drop-in replacement 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, surface and polished alloy steel worm. This mixture develops a simple, work-hardened mating surface area of the bronze equipment which improves with prolonged service.
Worm gearing is a class of equipment reducers that utilizes correct angle, nonintersecting shafts. This form of reducer provides easy and quiet operation and permits the likelihood of large rate reductions. These gears can be found from share in a wide variety of ratios, from only 4:1 to as much as 3600:1. The compact design and building allows worm gear reducers to be placed in a relatively 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 actions between worm and the 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 utilize worm gearing are: conveyors, mixers and bucket elevators.

A worm equipment reducer is one kind of reduction gear box which contains a worm pinion insight, an output worm gear, and includes a right angle output orientation. This kind of reduction gear package is normally used to have a rated motor speed and create a low speed output with higher torque worth 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 because of the little diameter of its result gear.
worm gear reducerWorm equipment reducers are also a popular type of rate reducer because they offer the greatest speed reduction 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 gear reducer. Some of the most typical applications for worm gears can be found in tuning instruments, medical examining 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 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 manufactured with tough compression-molded glass-fill up 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 a choice of a solid or hollow result shaft and feature an adjustable mounting placement. Both the SW-1 and the SW-5, nevertheless, can endure shock loading much better than other decrease gearbox styles, making them perfect for demanding applications.

Worm Gear Reducers also known as worm gearbox or worm acceleration reducers. Worm equipment reducers are utilized for speed reduction and increasing the torque for electrical electric motor drives. You can decide to mount your NEMA engine to the reducer utilizing the NEMA C face flange or make use of a coupling. If you need a coupling for the output or input shaft find our coupling section for selecting a coupling. We offer four assemblies left hand and right hand and double result shaft and shaft insight and shaft result. Interchangeable with the majority of worm gear manufactures.

Description
The HDR Series worm gear reducers are found 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, remaining or dual output 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 offer an effective low cost solution to speed reduction and increased torque, with higher tolerances for shock loading than helical gear reducers.
In order to select a gearbox speed reducer, you will have to determine the mandatory torque and service factor for the application form. Click on 
“Specifications” above for a desk that will assist in determining the service element. For service factors above 1.0, multiply the mandatory torque by the provider factor.
