worm gear speed reducer

One 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 takes a minimum of space. Input and output shafts can be prolonged in either or both directions in horizontal or vertical arrangements adaptable to any installation requirement. Efficient motor speeds are reduced to sluggish speed requirements of many industrial machines in a single reduction.

The exclusive use 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 surface and polished alloy metal worm develops a easy, work hardened surface on the bronze gear. For this reason worm gears wear in and improve with extented service while various other gears are deteriorating. EP offers a broad selection of model configurations, sizes, ratios, and components from our standard product line.
Fabricated Designs
If your application involves severe shock loads or possible housing damage from external sources (as in steel mills or mobile tools applications) EP can provide fabricated steel housings with up to 48″ center distances. Fabricated housings provide maximum rigidity and strength which allows the transmission of higher horsepower amounts than are possible with standard cast iron devices. Extra heavy part plates connect the worm and gear shaft bearing supports, assuring proper meshing of the apparatus 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 velocity and reversed engineered reducers for the application, be it a new project or a primary drop-in replacement for a competitor’s velocity reducer. Fabricated steel reducers allow EP to match a competitor’s footprint, centerline, and shaft elevation 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 design also incorporates a hardened, floor and polished alloy metal worm. This mixture develops a even, work-hardened mating surface of the bronze gear which boosts with prolonged service.
Worm gearing is a course of gear reducers that utilizes correct angle, nonintersecting shafts. This style of reducer provides even and quiet procedure and allows for the probability of large acceleration reductions. These gears are available from share 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 placed in a comparatively small space. Thus, high reductions in a limited package size may be accomplished with this configuration. Our worm gear features the continuous sliding tooth actions between worm and the teeth. This increases the tolerance for large loads and shock loads. Worm gear drives offer users high reducing capacity for relatively low cost in comparison with various other types of gearing.
The use 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.

-Housing:Onetime we casting creats great rigidity for severe impacts. Outer cooling fins and inner lubrication essential oil diversion channel design to improve heat dissipation.
-Worm Shaft: Manufactured with Carbon alloyed Steel S45C or SCM415, precison machined and carburized to HRC45 or HRC60, after that for precision tooth grinding to make sure maximum contacting.
-Worm Wheel: Manufactured with Carbon alloy ALBC2, teeth are machined by precision CNC hobbing machine to sustain high impact.
A worm gear reducer is one type of reduction gear container which consists of a worm pinion insight, an output worm gear, and features a right angle output orientation. This kind of reduction gear container is normally used to have a rated motor speed and produce a low speed output with higher torque worth based on the decrease ratio. They often times can resolve space-saving problems since the worm gear reducer is one of the sleekest decrease gearboxes available due to the small diameter of its output gear.
worm gear reducerWorm equipment reducers are also a favorite type of quickness reducer because they provide the greatest speed reduction in the smallest package. With a high ratio of speed reduction and high torque result multiplier, it’s unsurprising that lots of power transmission systems make use of a worm equipment reducer. Some of the most typical applications for worm gears can be found in tuning instruments, medical examining 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 manufactured with tough compression-molded glass-fill polyester housings for a long lasting, long lasting, light weight speed reducer that’s also compact, non-corrosive, and nonmetallic.
Features
Our worm equipment reducers offer a choice of a good or hollow output shaft and show an adjustable mounting position. Both SW-1 and the SW-5, however, can withstand shock loading better than other reduction gearbox styles, making them well suited for demanding applications.

Worm Gear Reducers also referred to as worm gearbox or worm swiftness reducers. Worm gear reducers are used for speed decrease and increasing the torque for electrical engine drives. You can choose to install your NEMA electric motor to the reducer utilizing the NEMA C encounter flange or make use of a coupling. If you want a coupling for the result or input shaft find our coupling section for selecting a coupling. You can expect four assemblies left hands and right hand and double result shaft and shaft insight and shaft result. Interchangeable with most 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 lbs. 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 tools 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 use 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, left or dual output shafts or a hollow bore output. The indirect drive models are shaft input-shaft output boxes for make use of with sprocket or pulley drive systems. They offer an effective low priced solution to speed decrease 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 required torque and service factor for the application form. Click on “Specs” above for a desk that will assist in determining the service factor. For service elements above 1.0, multiply the required torque by the service factor.
