One reduction worm gearing provides high ratio reduction with couple of moving parts in a close-coupled small drive. The proper angle set up of driving-to-driven machine requires a the least space. Input and result 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 slower speed requirements of many industrial machines in one reduction.

The exclusive utilization of the involute Helicoid Thread form (with leaving side contact) on the worm and gear provides for high efficiencies, and long service lifestyle. The hardened ground and polished alloy steel worm develops a clean, work hardened surface on the bronze gear. For this reason worm gears use in and improve with prolonged service while various other gears are deteriorating. EP offers a wide selection of model configurations, sizes, ratios, and components from our standard product line.
Fabricated Designs
If your application involves serious shock loads or feasible 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 that allows the transmitting of higher horsepower amounts than are possible with standard cast iron devices. Extra heavy side plates connect the worm and gear shaft bearing facilitates, assuring proper meshing of the gear under all load conditions. In smaller sized sizes, fabricated metal reducers are interchangeable with EP standard cast iron reducers.
Custom Designs
EP can offer custom quickness and reversed engineered reducers for the application, be it a fresh project or a primary drop-in replacement for a competitor’s acceleration reducer. Fabricated metal reducers enable EP to complement a competitor’s footprint, centerline, and shaft height allowing a direct drop-in substitute saving the client time and money.
Long – Quiet Life
All worm gears in EP reducers are produced from phosphorous bronze. Our style also incorporates a hardened, ground and polished alloy metal worm. This mixture develops a simple, work-hardened mating surface area of the bronze equipment which increases 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 operation and permits the likelihood of large swiftness reductions. These gears can be found from stock in a wide variety of ratios, from as low as 4:1 up to 3600:1. The small design and building allows worm gear reducers to be positioned in a comparatively small space. Thus, high reductions in a restricted package size may be accomplished with this configuration. Our worm equipment features the continuous sliding tooth action between worm and one’s teeth. This escalates the tolerance for heavy 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 utilization 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 type of reduction gear package which consists of a worm pinion insight, an output worm equipment, and includes a right angle result orientation. This kind of reduction gear package is normally used to have a rated motor velocity and create a low speed result with higher torque worth 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 little diameter of its output gear.
worm gear reducerWorm equipment reducers are also a favorite type of speed 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 utilize a worm gear reducer. Some of the most common applications for worm gears can be found in tuning instruments, medical tests equipment, elevators, protection 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 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 of these options are manufactured with durable 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 equipment reducers offer a choice of a solid or hollow output shaft and show an adjustable mounting position. Both SW-1 and the SW-5, however, can endure shock loading better than other reduction gearbox styles, making them well suited for demanding applications.

Worm Gear Reducers also known as worm gearbox or worm speed reducers. Worm gear reducers are utilized for speed decrease and raising the torque for electrical motor drives. You can decide to mount your NEMA 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 observe our coupling section for selecting a coupling. We offer four assemblies left hand and right hand and double output shaft and shaft input and shaft result. Interchangeable with most worm gear manufactures.

EP DDVM series triple-reduction worm gear quickness 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 lbs for the DDVM-200. Mechanical HP input 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 can be found in four configurations: horizontal, vertical, shafted, and shaft mounted.
These reducers are perfect for water/waste-water devices drive applications such as for example thickeners and clarifiers, which need a vertical straight down shaft. Other available configurations also make EP triple decrease reducers perfect for make use of on mixers, elevators, solar power panels, astronomical telescopes, indexing tables, hoists, conveyors, or other process or components handling systems where huge torques/gradual speeds are needed.

Description
The HDR Series worm gear reducers are used 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 mount with either right, remaining or dual output shafts or a hollow bore output. The indirect drive models are shaft input-shaft result boxes for use with sprocket or pulley drive systems. They offer an effective low priced solution to speed reduction and increased torque, with higher tolerances for shock loading than helical equipment reducers.
In order to select a gearbox speed reducer, you will need to determine the mandatory torque and provider factor for the application. Click on “Specs” above for a table that will aid in identifying the service aspect. For service elements above 1.0, multiply the required torque by the service factor.
