Solitary reduction worm gearing offers high ratio reduction with couple of shifting parts in a close-coupled small drive. The proper 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 plans adaptable to any mounting requirement. Efficient electric motor speeds are decreased to slow speed requirements of many 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 lifestyle. The hardened floor and polished alloy metal worm develops a soft, work hardened surface area on the bronze gear. Because of this worm gears use in and improve with extented service while other gears are wearing out. EP offers a broad collection of model configurations, sizes, ratios, and add-ons 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) EP can provide fabricated steel housings with up to a 48″ center distances. Fabricated housings provide maximum rigidity and strength that allows the transmitting of higher horsepower levels than are possible with regular cast iron models. Extra heavy part plates connect the worm and equipment shaft bearing supports, assuring proper meshing of the gear under all load conditions. In smaller sizes, fabricated steel reducers are interchangeable with EP regular 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 velocity reducer. Fabricated steel reducers allow EP to complement a competitor’s footprint, centerline, and shaft elevation allowing a primary drop-in alternative 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 combination develops a smooth, work-hardened mating surface 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 operation and permits the possibility of large acceleration reductions. These gears are available from stock in a wide variety of ratios, from as low as 4:1 to as much as 3600:1. The small design and construction allows worm gear reducers to be positioned in a comparatively small space. Thus, high reductions in a limited package size can be achieved with this configuration. Our worm gear features the constant sliding tooth actions 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 when compared to various 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 make use of worm gearing are: conveyors, mixers and bucket elevators.

A worm equipment reducer is one type of reduction gear box which includes a worm pinion insight, an output worm gear, and features a right angle output orientation. This type of reduction gear package is normally used to take a rated motor acceleration and create a low speed result with higher torque worth based on the reduction ratio. They often times can solve space-saving problems because the worm gear reducer is among the sleekest reduction gearboxes available because of the little diameter of its result gear.
worm gear reducerWorm equipment reducers are also a favorite type of speed reducer because they offer the greatest speed reduction in the tiniest package. With a higher ratio of speed reduction and high torque output multiplier, it’s unsurprising that many power transmission systems utilize a worm equipment reducer. Some of the most typical applications for worm gears are available in tuning instruments, medical testing 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 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 these options are produced with durable compression-molded glass-fill polyester housings for a durable, long lasting, light-weight speed reducer that is also compact, non-corrosive, and nonmetallic.
Features
Our worm gear reducers offer a choice of a good or hollow output shaft and show an adjustable mounting position. Both the SW-1 and the SW-5, nevertheless, can endure shock loading better than other decrease gearbox styles, making them perfect for demanding applications.

Worm Equipment Reducers also called worm gearbox or worm rate reducers. Worm gear reducers are utilized for speed reduction and increasing the torque for electrical motor drives. You can decide to mount your NEMA engine 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 find our coupling section for selecting a coupling. You can expect four assemblies left hand and right hand and double output shaft and shaft input and shaft output. Interchangeable with many worm gear manufactures. See data sheet in product overview for diamensions. If you don’t see your type, make sure you Contact Us.

EP DDVM series triple-reduction worm gear rate reducers are available in ratios from 5000:1 to 175,000:1 and center distances from 7” to 20” (larger sizes on request). Result 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 well suited for water/waste-water gear drive applications such as for example thickeners and clarifiers, which require a vertical straight down shaft. Other offered configurations also make EP triple decrease reducers perfect for make use of on mixers, elevators, solar panels, astronomical telescopes, indexing tables, hoists, conveyors, or additional process or materials handling systems where large torques/slower speeds are needed.

Description
The HDR Series worm equipment 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 versions are 56C or 145TC flange install with either right, remaining or dual result 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 provide 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 program factor for the application. Click on “Specs” above for a table that will assist in identifying the service aspect. For service factors above 1.0, multiply the required torque by the provider factor.
