Single reduction worm gearing offers high ratio reduction with couple of shifting parts in a close-coupled small drive. The right angle arrangement of driving-to-driven machine requires a minimum of space. Input and output shafts can be extended in either or both directions in horizontal or vertical plans adaptable to any mounting 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 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 smooth, work hardened surface on the bronze equipment. Because of this worm gears wear in and improve with prolonged service while other gears are deteriorating. EP offers a wide collection of model configurations, sizes, ratios, and components from our standard product line.
Fabricated Designs
If the application involves severe shock loads or possible housing damage from external sources (as in steel mills or mobile equipment applications) EP can offer fabricated steel housings with up to a 48″ center distances. Fabricated housings provide maximum rigidity and strength which allows the tranny of higher horsepower amounts than are feasible with standard cast iron systems. Extra heavy aspect plates connect the worm and equipment shaft bearing facilitates, assuring proper meshing of the gear under all load circumstances. In smaller sized sizes, fabricated metal reducers are interchangeable with EP standard cast iron reducers.
Custom Designs
EP can provide custom swiftness and reversed engineered reducers for the application, be it a new project or a primary drop-in alternative to a competitor’s speed reducer. Fabricated metal reducers allow EP to complement a competitor’s footprint, centerline, and shaft elevation allowing a primary drop-in substitute saving the customer time and money.
Long – Quiet Life
All worm gears in EP reducers are manufactured from phosphorous bronze. Our design also incorporates a hardened, ground and polished alloy steel worm. This mixture develops a soft, 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 soft and quiet procedure and allows for the probability of large quickness reductions. These gears can be found from stock in a wide selection of ratios, from as low as 4:1 to as much as 3600:1. The small design and structure allows worm gear reducers to be positioned in a relatively small space. Thus, high reductions in a limited 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 weighty loads and shock loads. Worm gear drives offer users high reducing convenience of 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 equipment reducer is one type of reduction gear package which includes a worm pinion insight, an output worm equipment, and includes a right angle result orientation. This type of reduction gear package is generally used to take a rated motor swiftness and create a low speed result with higher torque worth based on the decrease ratio. They often times can solve space-saving problems since the worm equipment reducer is among the sleekest decrease gearboxes available due to the small diameter of its output gear.
worm gear reducerWorm equipment reducers are also a popular type of quickness reducer because they offer the greatest speed decrease in the tiniest package. With a higher ratio of speed decrease 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 can be found in tuning instruments, medical screening equipment, elevators, security 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 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 manufactured with tough compression-molded glass-fill up polyester housings for a durable, long lasting, light weight speed reducer that is also compact, non-corrosive, 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 much better than other decrease gearbox designs, making them well suited for demanding applications.

Worm Equipment Reducers also known as worm gearbox or worm quickness reducers. Worm gear reducers are utilized for speed decrease and increasing the torque for electric electric motor drives. You can choose to mount 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 discover our coupling section for selecting a coupling. You can expect four assemblies left hands and right hand and double result shaft and shaft input and shaft result. Interchangeable with many worm gear manufactures.

EP DDVM series triple-reduction worm gear acceleration reducers can be found in ratios from 5000:1 to 175,000:1 and middle distances from 7” to 20” (larger sizes on request). Output torque ranges from 33,000 in pounds. 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 can be found in four configurations: horizontal, vertical, shafted, and shaft installed.
These reducers are perfect for water/waste-water devices drive applications such as thickeners and clarifiers, which require a vertical straight down shaft. Other offered configurations also make EP triple decrease reducers perfect for use on mixers, elevators, solar panels, astronomical telescopes, indexing tables, hoists, conveyors, or other process or materials handling systems where large torques/slow speeds are needed.

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 attach with either right, left or dual output shafts or a hollow bore result. The indirect drive versions are shaft input-shaft output boxes for use with sprocket or pulley drive systems. They provide an effective low priced solution to speed reduction and improved torque, with higher tolerances for shock loading than helical equipment reducers.
In order to select a gearbox speed reducer, you will have to determine the required torque and service factor for the application. Click on “Specifications” above for a table that will assist in determining the service element. For service elements above 1.0, multiply the mandatory torque by the services factor.
