worm gear speed reducer

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

The exclusive utilization of the involute Helicoid Thread form (with departing side contact) on the worm and gear offers high efficiencies, and lengthy service life. The hardened ground and polished alloy metal worm develops a clean, work hardened surface area on the bronze equipment. For this reason worm gears put on in and improve with extented service while various other gears are wearing out. Ever-Power offers a broad selection of model configurations, sizes, ratios, and accessories from our standard products.
Fabricated Designs
If the application involves severe shock loads or feasible housing damage from external sources (as in steel mills or mobile equipment 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 tranny of higher horsepower amounts than are feasible with regular cast iron devices. Extra heavy aspect plates connect the worm and equipment shaft bearing facilitates, assuring proper meshing of the apparatus under all load conditions. In smaller 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 direct drop-in replacement for a competitor’s swiftness reducer. Fabricated metal reducers allow Ever-Power to match a competitor’s footprint, centerline, and shaft height allowing a primary drop-in substitute 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, floor and polished alloy metal worm. This combination develops a soft, work-hardened mating surface area of the bronze equipment which boosts with prolonged service.
Worm gearing is a course of equipment reducers that utilizes right angle, nonintersecting shafts. This form of reducer provides easy and quiet operation and permits the probability of large quickness reductions. These gears can be found from share in a wide selection of ratios, from as low as 4:1 up to 3600:1. The small design and building allows worm gear reducers to be placed 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 continuous sliding tooth actions between worm and one’s teeth. This escalates the tolerance for large loads and shock loads. Worm gear drives provide users high reducing convenience of relatively low cost in comparison with some other types of gearing.
The use 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 contains a worm pinion input, an output worm equipment, and includes a right angle result orientation. This kind of reduction gear box is normally used to take a rated motor quickness and produce a low speed output with higher torque value based on the decrease ratio. They often can solve space-saving problems since the worm gear 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 swiftness reducer because they offer the greatest speed decrease in the tiniest 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 equipment reducer. Some of the most common applications for worm gears can be found in tuning instruments, medical assessment equipment, elevators, security gates, and conveyor belts.
SW-1 and SW-5
Torque Transmission provides 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 these options are manufactured with durable 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 equipment reducers offer an option of a solid or hollow result shaft and show an adjustable mounting placement. Both the SW-1 and the SW-5, however, can withstand shock loading better than other reduction gearbox designs, making them well suited for demanding applications.

Worm Equipment Reducers also referred to as worm gearbox or worm velocity reducers. Worm gear reducers are used for speed reduction and raising the torque for electric powered electric motor drives. You can decide to mount your NEMA motor to the reducer utilizing the NEMA C face flange or use a coupling. If you want a coupling for the result or input shaft see our coupling section for selecting a coupling. We offer four assemblies left hands and right hand and double result shaft and shaft insight and shaft output. Interchangeable with many worm gear manufactures. Observe data sheet in product overview for diamensions. If you don’t see your type, make sure you Contact Us.

Description
The HDR Series worm equipment reducers are found in low to moderate horsepower applications to 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 models 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 decrease 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 required torque and assistance factor for the application. Click on “Specifications” above for a table that will assist in identifying the service element. For service elements above 1.0, multiply the mandatory torque by the provider factor.
