worm gear speed reducer

One reduction worm gearing offers high ratio reduction with few shifting parts in a close-coupled small drive. The right angle set up of driving-to-driven machine takes a minimum of space. Input and result shafts can be prolonged in either or both directions in horizontal or vertical arrangements adaptable to any mounting requirement. Efficient engine speeds are decreased to slow speed requirements of many industrial machines in one 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 life. The hardened surface and polished alloy steel worm develops a even, work hardened surface area on the bronze equipment. For this reason worm gears use in and improve with extented service while additional gears are deteriorating. EP offers a broad collection of model configurations, sizes, ratios, and add-ons from our standard product line.
Fabricated Designs
If your application involves serious shock loads or feasible housing damage from external sources (as in steel mills or mobile gear applications) EP can offer fabricated steel housings with up to a 48″ center distances. Fabricated housings provide optimum rigidity and strength which allows the tranny of higher horsepower amounts than are feasible with standard cast iron models. Extra heavy aspect plates connect the worm and equipment shaft bearing supports, assuring correct meshing of the apparatus under all load conditions. In smaller sizes, fabricated steel reducers are interchangeable with EP regular cast iron reducers.
Custom Designs
EP can offer custom speed and reversed engineered reducers for your application, be it a new project or a primary drop-in replacement for a competitor’s quickness reducer. Fabricated steel reducers enable EP to complement a competitor’s footprint, centerline, and shaft height allowing a direct drop-in replacement 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, surface and polished alloy metal worm. This combination develops a soft, work-hardened mating surface of the bronze equipment which enhances with prolonged service.
Worm gearing is a course of equipment reducers that utilizes correct angle, nonintersecting shafts. This form of reducer provides smooth and quiet procedure and allows for the likelihood of large quickness reductions. These gears can be found from stock in a wide selection of ratios, from only 4:1 up to 3600:1. The compact design and structure allows worm equipment reducers to be positioned in a relatively small space. Thus, high reductions in a limited package size may be accomplished with this configuration. Our worm equipment features the continuous sliding tooth actions between worm and the teeth. This escalates the tolerance for heavy loads and shock loads. Worm gear drives provide users high reducing convenience of relatively low cost in comparison with some 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 use worm gearing are: conveyors, mixers and bucket elevators.
EP worm equipment reducer gearbox series base on years of experiences uses designed teeth surface with unsurpassed torque transfer efficiency with great efficiency, efficency and price.Worm gear system transmits power through sliding contact, leading to extremely low vibration , sound, small backlash and self-locking property
-Housing:One time we casting creats great rigidity for severe impacts. Outer cooling fins and inner lubrication oil diversion channel style to increase 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 ensure 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 box which contains a worm pinion insight, an output worm equipment, and features a right angle result orientation. This kind of reduction gear container is generally used to take a rated motor quickness and produce a low speed result with higher torque worth based on the reduction ratio. They often times can resolve space-saving problems because the worm equipment reducer is one of the sleekest reduction gearboxes available due to the little diameter of its output gear.
worm gear reducerWorm equipment reducers are also a favorite type of speed reducer because they provide the greatest speed decrease in the smallest package. With a higher 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 common applications for worm gears are available in tuning instruments, medical screening equipment, elevators, security 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 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 produced 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 placement. Both SW-1 and the SW-5, nevertheless, can withstand shock loading better than other reduction gearbox designs, making them perfect for demanding applications.

Worm Gear Reducers also referred to as worm gearbox or worm speed reducers. Worm equipment reducers are used for speed reduction and increasing the torque for electric electric motor drives. You can choose to install your NEMA engine to the reducer by using the NEMA C face flange or make use of a coupling. If you need a coupling for the output or input shaft discover our coupling section for choosing the coupling. We offer four assemblies left hand and right hands and double result shaft and shaft input and shaft result. Interchangeable with many worm gear manufactures. Observe data sheet in item overview for diamensions. If you don’t see your type, make sure you Contact Us.

Description
The HDR Series worm equipment reducers are used in low to moderate horsepower applications to reduce speeds and increase torque. Worm gear reducers are available in direct or indirect drive, direct drive versions are 56C or 145TC flange attach with either right, still left or dual result shafts or a hollow bore result. The indirect drive models are shaft input-shaft result boxes for make use of with sprocket or pulley drive systems. They provide an effective low priced solution to speed decrease and improved 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 mandatory torque and provider factor for the application. Click on “Specifications” above for a table that will aid in determining the service element. For service elements above 1.0, multiply the mandatory torque by the services factor.
