worm gear speed reducer

worm gear speed reducer
Single reduction worm gearing offers high ratio reduction with few moving parts in a close-coupled compact drive. The proper angle arrangement 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 engine speeds are decreased to gradual speed requirements of several industrial machines in a single reduction.

The exclusive utilization of the involute Helicoid Thread form (with departing side contact) on the worm and gear provides for high efficiencies, and long service life. The hardened floor and polished alloy steel worm develops a easy, work hardened surface area on the bronze equipment. For this reason worm gears put on in and improve with extented service while additional gears are wearing out. Ever-Power offers a broad collection of model configurations, sizes, ratios, and accessories from our standard product line.
Fabricated Designs
If your application involves severe 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 maximum rigidity and strength which allows the transmitting of higher horsepower levels than are feasible with regular cast iron models. Extra heavy side plates connect the worm and equipment shaft bearing facilitates, assuring correct meshing of the apparatus under all load circumstances. In smaller sized sizes, fabricated metal reducers are interchangeable with Ever-Power standard 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 primary drop-in alternative to 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 alternative saving the client time and money.
Long – Quiet Life
All worm gears in Ever-Power reducers are manufactured from phosphorous bronze. Our style also includes a hardened, surface and polished alloy steel worm. This mixture develops a simple, work-hardened mating surface area of the bronze gear which increases with prolonged service.
Worm gearing is a class of gear reducers that utilizes correct angle, nonintersecting shafts. This style of reducer provides simple and quiet operation and permits the possibility of large acceleration 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 small design and construction allows worm gear reducers to be placed 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 actions 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 when compared to 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 make use of worm gearing are: conveyors, mixers and bucket elevators.

A worm equipment reducer is one type of reduction gear box which consists of a worm pinion insight, an output worm gear, and includes a right angle result orientation. This type of reduction gear box is normally used to take a rated motor rate and produce a low speed result with higher torque worth based on the reduction ratio. They often times can solve space-saving problems since the worm gear reducer is one of the sleekest reduction gearboxes available due to the small diameter of its output gear.
worm gear reducerWorm gear reducers are also a favorite type of quickness reducer because they offer the greatest speed reduction in the smallest package. With a higher ratio of speed reduction and high torque result multiplier, it’s unsurprising that lots of power transmission systems utilize a worm gear reducer. Some of the most common applications for worm gears are available in tuning instruments, medical examining 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 are available 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 of 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, 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 SW-1 and the SW-5, however, can withstand shock loading better than other reduction gearbox designs, making them ideal for demanding applications.

Worm Gear Reducers also referred to as worm gearbox or worm quickness reducers. Worm gear reducers are utilized for speed decrease and increasing the torque for electric powered engine drives. You can decide to mount your NEMA engine to the reducer by using the NEMA C face flange or use a coupling. If you need a coupling for the output or input shaft find our coupling section for selecting a coupling. You can expect four assemblies left hands and right hands and double result shaft and shaft input and shaft output. Interchangeable with many 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 are available in direct or indirect drive, direct drive models are 56C or 145TC flange mount with either right, left or dual result shafts or a hollow bore result. The indirect drive models are shaft input-shaft output boxes for make use of with sprocket or pulley drive systems. They offer an effective low cost solution to speed decrease and improved torque, with higher tolerances for shock loading than helical gear reducers.
In order to select a gearbox speed reducer, you will need to determine the required torque and assistance factor for the application. Click on “Specs” above for a table that will assist in determining the service aspect. For service factors above 1.0, multiply the mandatory torque by the provider factor.
