worm gear speed reducer

Single reduction worm gearing provides high ratio reduction with couple of moving parts in a close-coupled compact drive. The proper angle set up of driving-to-driven machine requires a minimum of space. Input and result shafts can be extended in either or both directions in horizontal or vertical arrangements adaptable to any mounting requirement. Efficient motor speeds are decreased to gradual speed requirements of many 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 lengthy service life. The hardened ground and polished alloy metal worm develops a soft, work hardened surface area on the bronze equipment. Because of this worm gears use in and improve with extented service while additional gears are deteriorating. Ever-Power offers a wide selection of model configurations, sizes, ratios, and add-ons from our standard products.
Fabricated Designs
If the application involves serious shock loads or feasible housing damage from external sources (as in steel mills or mobile equipment applications) Ever-Power can provide fabricated steel housings with up to a 48″ center distances. Fabricated housings provide optimum rigidity and strength that allows the tranny of higher horsepower levels than are feasible with regular cast iron systems. Extra heavy side plates connect the worm and equipment shaft bearing facilitates, assuring appropriate meshing of the gear under all load circumstances. In smaller sizes, fabricated steel reducers are interchangeable with Ever-Power regular cast iron reducers.
Custom Designs
Ever-Power can provide custom swiftness and reversed engineered reducers for your application, be it a fresh project or a direct drop-in alternative to a competitor’s swiftness 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 design also includes a hardened, surface and polished alloy steel worm. This combination develops a easy, work-hardened mating surface area of the bronze equipment which improves with prolonged service.
Worm gearing is a class of equipment reducers that utilizes right angle, nonintersecting shafts. This style of reducer provides clean and quiet operation and permits the possibility of large speed reductions. These gears are available from stock in a wide selection of ratios, from only 4:1 up to 3600:1. The compact design and structure allows worm equipment reducers to be positioned in a relatively small space. Thus, very high reductions in a restricted package size can be achieved with this configuration. Our worm equipment features the constant sliding tooth action between worm and one’s teeth. This escalates the tolerance for weighty loads and shock loads. Worm gear drives provide users high reducing convenience of relatively low cost when compared to some 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 equipment reducer is one kind of reduction gear box which includes a worm pinion input, an output worm equipment, and features a right angle result orientation. This type of reduction gear package is generally used to take a rated motor acceleration and create a low speed result with higher torque value based on the reduction ratio. They often can solve space-saving problems because the worm equipment reducer is one of the sleekest reduction gearboxes available due to the little diameter of its result gear.
worm gear reducerWorm gear reducers are also a popular type of speed reducer because they provide 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 tests 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 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 produced with durable compression-molded glass-fill up polyester housings for a durable, long lasting, light-weight speed reducer that is also compact, non-corrosive, and nonmetallic.
Features
Our worm gear reducers offer an option of a solid or hollow output 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 designs, making them ideal for demanding applications.

Worm Equipment Reducers also called worm gearbox or worm quickness reducers. Worm equipment reducers are utilized for speed reduction and raising the torque for electric powered motor drives. You can decide to attach your NEMA engine to the reducer by using the NEMA C face flange or make use of a coupling. If you need a coupling for the output or input shaft see our coupling section for choosing the coupling. We offer four assemblies left hand and right hand and double output shaft and shaft input and shaft output. Interchangeable with many worm gear manufactures.

Description
The HDR Series worm gear reducers are found in low to moderate horsepower applications to worm gear speed reducer lessen speeds and increase torque. Worm gear reducers are available in direct or indirect drive, direct drive models are 56C or 145TC flange install with either right, remaining or dual result shafts or a hollow bore result. 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 priced 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 have to determine the mandatory torque and assistance factor for the application. Click on “Specs” above for a table that will aid in identifying the service element. For service factors above 1.0, multiply the mandatory torque by the program factor.
