worm gear speed reducer

Single reduction worm gearing offers high ratio reduction with couple of shifting parts in a close-coupled compact drive. The proper angle arrangement of driving-to-driven machine takes a the least 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 reduced 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 offers high efficiencies, and long service lifestyle. The hardened ground and polished alloy steel worm develops a simple, work hardened surface on the bronze gear. Because of this worm gears put on in and improve with prolonged service while various other gears are deteriorating. EP offers a wide collection of model configurations, sizes, ratios, and accessories 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 tools applications) EP can provide fabricated steel housings with up to 48″ center distances. Fabricated housings provide maximum rigidity and strength which allows the transmitting of higher horsepower levels than are feasible with standard cast iron products. Extra heavy aspect plates connect the worm and gear shaft bearing facilitates, assuring proper meshing of the apparatus under all load circumstances. In smaller sizes, fabricated steel reducers are interchangeable with EP regular cast iron reducers.
Custom Designs
EP can provide custom quickness and reversed engineered reducers for your application, be it a new project or a direct drop-in alternative to a competitor’s quickness reducer. Fabricated metal reducers enable EP to match a competitor’s footprint, centerline, and shaft height allowing a direct drop-in alternative saving the client time and money.
Long – Quiet Life
All worm gears in EP reducers are produced from phosphorous bronze. Our style also includes a hardened, floor and polished alloy steel worm. This mixture develops a easy, work-hardened mating surface of the bronze gear which boosts with prolonged service.
Worm gearing is a course of equipment reducers that utilizes correct angle, nonintersecting shafts. This style of reducer provides clean and quiet operation and allows for the likelihood of large swiftness reductions. These gears are available from share in a wide selection of ratios, from as low as 4:1 up to 3600:1. The small design and structure allows worm gear reducers to be placed in a comparatively small space. Thus, very high reductions in a limited package size may be accomplished with this configuration. Our worm gear features the constant sliding tooth action between worm and one’s teeth. This increases the tolerance for weighty loads and shock loads. Worm gear drives provide users high reducing convenience of relatively low cost when compared to 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 make use of worm gearing are: conveyors, mixers and bucket elevators.
EP worm gear reducer gearbox series base on years of experiences uses designed teeth surface with unsurpassed torque transfer efficiency with great functionality, efficency and cost.Worm gear system transmits power through sliding contact, leading to extremely low vibration , sound, little backlash and self-locking property
-Housing:One time we casting creats great rigidity for serious impacts. Outer cooling fins and internal lubrication oil diversion channel style to increase heat dissipation.
-Worm Shaft: Manufactured with Carbon alloyed Metal 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 equipment reducer is one kind of reduction gear package which contains a worm pinion insight, an output worm gear, and includes a right angle result orientation. This type of reduction gear container is normally used to have a rated motor velocity and create a low speed output with higher torque value based on the reduction 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 little diameter of its result gear.
worm gear reducerWorm equipment reducers are also a popular type of rate reducer because they provide the greatest speed reduction in the tiniest package. With a high ratio of speed decrease and high torque result multiplier, it’s unsurprising that many power transmission systems utilize a worm equipment reducer. Some of the most typical applications for worm gears can be found in tuning instruments, medical testing equipment, elevators, protection 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 these options are manufactured with rugged compression-molded glass-fill polyester housings for a durable, long lasting, light-weight speed reducer that is also compact, noncorrosive, and nonmetallic.
Features
Our worm gear reducers offer a choice of a solid or hollow output shaft and show an adjustable mounting placement. Both SW-1 and the SW-5, however, can withstand shock loading better than other reduction gearbox designs, making them well suited for demanding applications.

Worm Equipment Reducers also known as worm gearbox or worm swiftness reducers. Worm gear reducers are used for speed reduction and increasing the torque for electrical motor drives. You can decide to attach your NEMA motor to the reducer by using the NEMA C face flange or use a coupling. If you need a coupling for the output or input shaft discover our coupling section for selecting a coupling. We offer four assemblies left hand and right hands and double output shaft and shaft insight and shaft result. Interchangeable with most worm gear manufactures.

EP DDVM series triple-reduction worm gear rate reducers can be found 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 input 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 well suited for water/waste-water apparatus drive applications such as thickeners and clarifiers, which require a vertical straight down shaft. Other offered configurations also make EP triple reduction reducers perfect for make use of on mixers, elevators, solar panels, astronomical telescopes, indexing tables, hoists, conveyors, or various other process or components handling systems where large torques/slower speeds are needed.
These reducers are also obtainable with a helical main reduction stage and so are termed the HDVM series

Description
The HDR Series worm equipment reducers are found 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 models are 56C or 145TC flange mount with either right, still left or dual output shafts or a hollow bore output. The indirect drive versions 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 improved torque, with higher tolerances for shock loading than helical gear reducers.
In order to select a gearbox speed reducer, you will have to determine the required torque and provider factor for the application form. Click on “Specs” above for a desk that will assist in determining the service aspect. For service factors above 1.0, multiply the mandatory torque by the services factor.
