worm gear speed reducer

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 arrangement of driving-to-driven machine requires a the least space. Input and output shafts can be extended in either or both directions in horizontal or vertical plans adaptable to any installation requirement. Efficient electric motor speeds are decreased to slower speed requirements of several industrial machines in one reduction.

The exclusive use of the involute Helicoid Thread form (with leaving side contact) on the worm and gear provides for high efficiencies, and lengthy service lifestyle. The hardened surface and polished alloy metal worm develops a smooth, work hardened surface on the bronze gear. Because of this worm gears put on in and improve with extented service while various other gears are deteriorating. Ever-Power offers a broad collection of model configurations, sizes, ratios, and accessories from our standard products.
Fabricated Designs
If the application involves serious shock loads or possible housing damage from external sources (as in steel mills or mobile devices applications) Ever-Power can provide fabricated steel housings with up to a 48″ center distances. Fabricated housings provide optimum rigidity and strength which allows the transmitting of higher horsepower levels than are feasible with standard cast iron devices. Extra heavy aspect plates connect the worm and equipment shaft bearing facilitates, assuring correct meshing of the gear under all load circumstances. In smaller sizes, fabricated steel reducers are interchangeable with Ever-Power standard cast iron reducers.
Custom Designs
Ever-Power can provide custom acceleration and reversed engineered reducers for the application, be it a new project or a direct drop-in replacement for a competitor’s acceleration reducer. Fabricated metal reducers allow Ever-Power to match a competitor’s footprint, centerline, and shaft elevation allowing a direct 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, ground and polished alloy metal worm. This combination develops a soft, work-hardened mating surface area of the bronze equipment which enhances with prolonged service.
Worm gearing is a course of equipment reducers that utilizes correct angle, nonintersecting shafts. This style of reducer provides smooth and quiet procedure and allows for the likelihood of large acceleration reductions. These gears are available from share in a wide selection of ratios, from as low as 4:1 up to 3600:1. The small design and construction allows worm gear reducers to be positioned in a relatively small space. Thus, high reductions in a restricted package size can be achieved with this configuration. Our worm gear features the continuous sliding tooth action between worm and the teeth. This increases the tolerance for weighty loads and shock loads. Worm gear drives provide users high reducing capacity for relatively low cost in comparison with 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 gear reducer is one type of reduction gear box which consists of a worm pinion input, an output worm equipment, and includes a right angle output orientation. This type of reduction gear container is normally used to take a rated motor speed and produce a low speed result with higher torque value based on the decrease ratio. They often times can resolve space-saving problems because the worm equipment reducer is one of the sleekest reduction gearboxes available because of the small diameter of its output gear.
worm gear reducerWorm gear reducers are also a popular type of quickness reducer because they provide the greatest speed reduction in the tiniest package. With a higher ratio of speed reduction and high torque result multiplier, it’s unsurprising that many power transmission systems utilize a worm gear reducer. Some of the most common applications for worm gears can be found in tuning instruments, medical testing equipment, elevators, protection gates, and conveyor belts.
SW-1 and SW-5
Torque Transmission offers two sizes of worm gear 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’s 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 position. Both SW-1 and the SW-5, nevertheless, can withstand shock loading much better than other reduction gearbox designs, making them perfect for demanding applications.

Worm Gear Reducers also known as worm gearbox or worm velocity reducers. Worm equipment reducers are used for speed decrease and increasing the torque for electrical engine drives. You can choose to install your NEMA motor to the reducer utilizing the NEMA C encounter flange or make use of a coupling. If you need a coupling for the result or input shaft observe our coupling section for selecting a coupling. You can expect four assemblies left hands and right hand and double output shaft and shaft input and shaft result. Interchangeable with the majority of worm gear manufactures.

Description
The HDR Series worm gear reducers are used in low to moderate horsepower applications to lessen speeds and increase torque. Worm gear reducers can be found in direct or indirect drive, direct drive versions are 56C or 145TC flange attach with either right, left 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 priced 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 have to determine the mandatory torque and support factor for the application form. Click on “Specs” above for a table that will aid in determining the service aspect. For service factors above 1.0, multiply the mandatory torque by the service factor.
