Single reduction worm gearing offers high ratio reduction with couple of shifting parts in a close-coupled compact drive. The right angle arrangement of driving-to-driven machine requires 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 engine 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 offers high efficiencies, and long service life. The hardened ground and polished alloy metal worm develops a smooth, work hardened surface on the bronze gear. For this reason worm gears wear 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 the application involves severe shock loads or feasible 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 levels than are feasible with standard cast iron devices. Extra heavy part 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 direct drop-in alternative to a competitor’s quickness reducer. Fabricated metal reducers allow EP to match a competitor’s footprint, centerline, and shaft height allowing a direct 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 includes a hardened, ground and polished alloy steel worm. This combination develops a easy, work-hardened mating surface of the bronze gear which boosts with prolonged service.
Worm gearing is a class of equipment reducers that utilizes correct angle, nonintersecting shafts. This style of reducer provides easy and quiet procedure and allows for the possibility of large rate reductions. These gears can be found from stock in a wide variety 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 comparatively small space. Thus, high reductions in a limited package size can be achieved with this configuration. Our worm equipment features the continuous sliding tooth action between worm and the teeth. This escalates the tolerance for weighty loads and shock loads. Worm gear drives provide users high reducing convenience of relatively low cost in comparison with 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 utilize worm gearing are: conveyors, mixers and bucket elevators.

A worm gear reducer is one kind of reduction gear package which consists of a worm pinion insight, an output worm equipment, and includes a right angle output orientation. This kind of reduction gear package is generally used to have 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 one of the sleekest reduction gearboxes available because of the small diameter of its output gear.
worm gear reducerWorm equipment reducers are also a popular type of acceleration reducer because they offer the greatest speed reduction 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 typical 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 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 of these options are manufactured with durable compression-molded glass-fill polyester housings for a durable, 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 result shaft and show an adjustable mounting placement. Both SW-1 and the SW-5, nevertheless, can endure shock loading much better than other decrease gearbox designs, making them perfect for demanding applications.

Worm Equipment Reducers also referred to as worm gearbox or worm swiftness reducers. Worm gear reducers are utilized for speed reduction and increasing the torque for electric powered electric motor drives. You can choose to install your NEMA electric motor to the reducer by using the NEMA C face flange or make use of a coupling. If you want a coupling for the result or input shaft observe our coupling section for selecting a coupling. We offer four assemblies left hand and right hands and double result shaft and shaft insight and shaft result. Interchangeable with many worm gear manufactures. See data sheet in item overview for diamensions. Unless you see your type, make sure you Contact Us.

Description
The HDR Series worm equipment reducers are found in low to moderate horsepower applications to reduce 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 output. The indirect drive models are shaft input-shaft output 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 have to determine the required torque and program factor for the application. Click on “Specifications” above for a table that will assist in determining the service element. For service factors above 1.0, multiply the mandatory torque by the support factor.
