worm gear speed reducer

One reduction worm gearing offers high ratio reduction with couple of moving parts in a close-coupled compact drive. The right angle arrangement of driving-to-driven machine takes a minimum of space. Input and output shafts can be prolonged in either or both directions in horizontal or vertical arrangements adaptable to any installation requirement. Efficient electric 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 long service lifestyle. The hardened floor and polished alloy steel worm develops a even, work hardened surface on the bronze equipment. For this reason worm gears wear in and improve with prolonged service while other gears are wearing out. EP offers a wide collection of model configurations, sizes, ratios, and accessories from our standard products.
Fabricated Designs
If your application involves serious shock loads or possible housing damage from external sources (as in steel mills or mobile gear applications) EP 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 amounts than are possible with standard cast iron products. Extra heavy part plates connect the worm and gear shaft bearing facilitates, assuring correct meshing of the gear under all load conditions. In smaller sizes, fabricated metal reducers are interchangeable with EP standard cast iron reducers.
Custom Designs
EP can offer custom speed and reversed engineered reducers for your application, be it a new project or a direct drop-in replacement for a competitor’s speed reducer. Fabricated metal reducers allow EP 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 EP reducers are manufactured from phosphorous bronze. Our style also includes a hardened, surface and polished alloy steel worm. This combination develops a clean, work-hardened mating surface area of the bronze equipment which improves with prolonged service.
Worm gearing is a class of gear reducers that utilizes correct angle, nonintersecting shafts. This style of reducer provides clean and quiet procedure and allows for the possibility of large quickness reductions. These gears are available from share in a wide selection of ratios, from only 4:1 up to 3600:1. The compact design and construction allows worm gear reducers to be placed in a relatively small space. Thus, very high reductions in a restricted package size may be accomplished with this configuration. Our worm equipment features the constant sliding tooth action between worm and the teeth. This increases 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 utilization 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 gear reducer is one type of reduction gear container which consists of a worm pinion insight, an output worm equipment, and features a right angle result orientation. This type of reduction gear package is normally used to take a rated motor speed and create a low speed output with higher torque value based on the reduction ratio. They often can resolve space-saving problems since the worm equipment reducer is among the sleekest reduction gearboxes available due to the little diameter of its result gear.
worm gear reducerWorm gear reducers are also a favorite type of acceleration reducer because they provide the greatest speed decrease in the smallest package. With a higher ratio of speed reduction and high torque result multiplier, it’s unsurprising that many power transmission systems make use of a worm equipment 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 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 rugged compression-molded glass-fill polyester housings for a durable, long lasting, light-weight speed reducer that is also compact, noncorrosive, and nonmetallic.
Features
Our worm gear reducers offer a choice of a solid or hollow result shaft and show an adjustable mounting placement. Both the SW-1 and the SW-5, nevertheless, can withstand shock loading better than other reduction gearbox designs, making them ideal for demanding applications.

Worm Gear Reducers also known as worm gearbox or worm velocity reducers. Worm gear reducers are utilized for speed decrease and increasing the torque for electrical motor drives. You can choose to attach your NEMA electric motor to the reducer by using the NEMA C face flange or use a coupling. If you need a coupling for the result or input shaft see our coupling section for choosing the coupling. You can expect four assemblies left hand and right hand and double result shaft and shaft insight and shaft output. Interchangeable with most worm gear manufactures. See data sheet in item overview for diamensions. If you don’t see your type, make sure you Contact Us.

EP DDVM series triple-reduction worm gear speed reducers can be found in ratios from 5000:1 to 175,000:1 and center distances from 7” to 20” (larger sizes available on request). Output torque ranges from 33,000 in lbs. for the 7” CD DDVM-70 to 582,900 in pounds for the DDVM-200. Mechanical HP insight requirements are from 0.09 HP for the 175,000:1 7 in CD reducer to 6.25 HP for the 5000:1 20” CD unit. These reducers are available in four configurations: horizontal, vertical, shafted, and shaft installed.
These reducers are well suited for water/waste-water gear drive applications such as for example thickeners and clarifiers, which require a vertical straight down shaft. Other available configurations also make EP triple reduction reducers perfect for use on mixers, elevators, solar panels, astronomical telescopes, indexing tables, hoists, conveyors, or various other process or materials handling systems where large torques/slower speeds are needed.
These reducers are also obtainable with a helical major reduction stage and so are termed the HDVM series

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 models are 56C or 145TC flange attach with either right, still left or dual output shafts or a hollow bore result. The indirect drive models are shaft input-shaft output boxes for use with sprocket or pulley drive systems. They provide an effective low cost solution to speed reduction and improved torque, with higher tolerances for shock loading than helical gear reducers.
In order to decide on a gearbox speed reducer, you will need to determine the mandatory torque and support factor for the application. Click on “Specs” above for a table that will aid in determining the service aspect. For service elements above 1.0, multiply the required torque by the support factor.
