worm gear speed reducer

Solitary reduction worm gearing provides high ratio reduction with couple of shifting parts in a close-coupled compact drive. The right angle set up 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 motor speeds are decreased to sluggish speed requirements of several industrial machines in a single reduction.

The exclusive usage of the involute Helicoid Thread form (with departing side contact) on the worm and gear offers high efficiencies, and long service existence. The hardened surface and polished alloy steel worm develops a clean, work hardened surface area on the bronze gear. Because of this 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 products.
Fabricated Designs
If your application involves serious shock loads or possible housing damage from external sources (as in steel mills or mobile gear applications) EP can provide fabricated steel housings with up to a 48″ center distances. Fabricated housings provide optimum rigidity and strength that allows the transmission of higher horsepower levels than are possible with regular cast iron devices. Extra heavy side plates connect the worm and gear shaft bearing facilitates, assuring proper meshing of the gear under all load circumstances. In smaller sizes, fabricated metal reducers are interchangeable with EP regular cast iron reducers.
Custom Designs
EP can offer custom quickness and reversed engineered reducers for the application, be it a fresh project or a primary drop-in alternative to a competitor’s velocity reducer. Fabricated metal reducers enable EP to complement a competitor’s footprint, centerline, and shaft elevation allowing a primary drop-in substitute saving the customer time and money.
Long – Quiet Life
All worm gears in EP reducers are produced from phosphorous bronze. Our design also incorporates a hardened, ground and polished alloy metal worm. This combination develops a smooth, work-hardened mating surface area of the bronze gear which enhances with prolonged service.
Worm gearing is a course of equipment reducers that utilizes correct angle, nonintersecting shafts. This style of reducer provides even and quiet operation and permits the likelihood of large acceleration reductions. These gears can be found 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, high reductions in a limited package size may be accomplished with this configuration. Our worm gear features the constant sliding tooth actions between worm and the teeth. This increases the tolerance for weighty 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 utilization 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.

A worm equipment reducer is one type of reduction gear box which consists of a worm pinion insight, an output worm gear, and features a right angle output orientation. This kind of reduction gear box is generally used to take a rated motor swiftness and produce a low speed result with higher torque worth based on the reduction ratio. They often times can solve space-saving problems since the worm gear reducer is among the sleekest reduction gearboxes available due to the small diameter of its output gear.
worm gear reducerWorm gear reducers are also a favorite type of velocity reducer because they provide the greatest speed decrease in the tiniest package. With a higher ratio of speed reduction and high torque output multiplier, it’s unsurprising that lots of power transmission systems utilize a worm equipment reducer. Some of the most common applications for worm gears can be found in tuning instruments, medical assessment equipment, elevators, protection gates, and conveyor belts.
SW-1 and SW-5
Torque Transmission offers two sizes of worm equipment reducer, the SW-1 and the SW-5 and both can be found 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 these options are manufactured with durable compression-molded glass-fill up polyester housings for a long lasting, long lasting, light-weight speed reducer that is also compact, non-corrosive, and nonmetallic.
Features
Our worm gear reducers offer a choice of a solid or hollow output shaft and feature an adjustable mounting placement. Both SW-1 and the SW-5, however, can endure shock loading better than other reduction gearbox styles, making them perfect for demanding applications.

Worm Gear Reducers also called worm gearbox or worm swiftness reducers. Worm equipment reducers are used for speed decrease and increasing the torque for electric engine drives. You can decide to mount your NEMA engine to the reducer utilizing the NEMA C encounter flange or use a coupling. If you need a coupling for the result or input shaft observe our coupling section for choosing the coupling. We offer four assemblies left hands and right hand and double result shaft and shaft insight and shaft result. Interchangeable with many worm gear manufactures.

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 versions are 56C or 145TC flange mount with either right, remaining or dual result shafts or a hollow bore output. The indirect drive versions 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 decide on a gearbox speed reducer, you will need to determine the mandatory torque and service factor for the application. Click on “Specs” above for a table that will aid in identifying the service factor. For service factors above 1.0, multiply the required torque by the program factor.
