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 prolonged in either or both directions in horizontal or vertical arrangements adaptable to any mounting requirement. Efficient electric motor speeds are decreased to gradual speed requirements of many industrial machines in one 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 steel worm develops a clean, work hardened surface on the bronze equipment. For this reason worm gears wear in and improve with prolonged service while various other gears are wearing out. EP offers a wide selection of model configurations, sizes, ratios, and add-ons 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 apparatus applications) EP can offer fabricated steel housings with up to 48″ center distances. Fabricated housings provide maximum rigidity and strength that allows the tranny of higher horsepower levels than are feasible with regular cast iron devices. Extra heavy part plates connect the worm and gear shaft bearing supports, assuring appropriate meshing of the apparatus under all load conditions. In smaller sized sizes, fabricated steel reducers are interchangeable with EP standard cast iron reducers.
Custom Designs
EP can provide custom velocity and reversed engineered reducers for the application, be it a fresh project or a primary drop-in replacement for a competitor’s swiftness reducer. Fabricated metal reducers allow EP to complement a competitor’s footprint, centerline, and shaft height allowing a direct drop-in replacement saving the customer time and money.
Long – Quiet Life
All worm gears in EP reducers are manufactured from phosphorous bronze. Our style also incorporates a hardened, ground and polished alloy steel worm. This combination develops a clean, work-hardened mating surface area of the bronze gear which boosts with prolonged service.
Worm gearing is a course of gear reducers that utilizes right angle, nonintersecting shafts. This style of reducer provides soft and quiet procedure and permits the likelihood 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 compact design and structure allows worm equipment reducers to be positioned in a comparatively small space. Thus, very 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 escalates the tolerance for large loads and shock loads. Worm gear drives provide users 
high reducing capacity for relatively low cost in comparison with various 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 use 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 equipment, and features a right angle output orientation. This kind of reduction gear box is generally used to have a rated motor velocity 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 one of the sleekest decrease gearboxes available because of the small diameter of its output gear.
worm gear reducerWorm gear reducers are also a favorite type of rate reducer because they provide the greatest speed decrease in the smallest package. With a higher ratio of speed reduction and high torque output multiplier, it’s unsurprising that lots of power transmission systems make use of a worm gear reducer. Some of the most common applications for worm gears are available in tuning instruments, medical testing equipment, elevators, protection gates, and conveyor belts.
SW-1 and SW-5
Torque Transmission provides two sizes of worm gear reducer, the SW-1 and the SW-5 and both are available 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 produced with rugged compression-molded glass-fill up polyester housings for a long lasting, long lasting, light weight speed reducer that’s 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 position. Both SW-1 and the SW-5, however, can endure shock loading much better than other reduction gearbox designs, making them perfect for demanding applications.

Worm Equipment Reducers also called worm gearbox or worm acceleration reducers. Worm gear reducers are used for speed decrease and raising the torque for electrical motor drives. You can choose to mount your NEMA motor to the reducer by using the NEMA C encounter flange or use a coupling. If you need a coupling for the result or input shaft see our coupling section for selecting a coupling. We offer four assemblies left hand and right hand and double output shaft and shaft insight and shaft output. Interchangeable with many worm gear manufactures.

EP DDVM series triple-reduction worm gear velocity reducers can be found in ratios from 5000:1 to 175,000:1 and middle 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 lbs 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 ideal for water/waste-water products drive applications such as thickeners and clarifiers, which require a vertical down shaft.

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 attach with either right, remaining 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 offer an effective low cost solution to speed reduction and increased 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 services factor for the application form. Click on “Specifications” above for a desk that will assist in identifying the service element. For service factors above 1.0, multiply the mandatory torque by the provider factor.
