worm gear speed reducer

Single reduction worm gearing provides high ratio reduction with few 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 plans adaptable to any mounting requirement. Efficient engine speeds are reduced to slow 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 provides for high efficiencies, and long service existence. The hardened floor and polished alloy steel worm develops a easy, work hardened surface area on the bronze equipment. Because of this worm gears put on in and improve with extented service while various other gears are deteriorating. EP offers a wide selection of model configurations, sizes, ratios, and add-ons from our standard products.
Fabricated Designs
If the application involves severe 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 that allows the transmission of higher horsepower levels than are possible with regular cast iron products. Extra heavy part plates connect the worm and equipment shaft bearing facilitates, assuring appropriate meshing of the gear under all load conditions. In smaller sizes, fabricated metal reducers are interchangeable with EP standard cast iron reducers.
Custom Designs
EP can offer custom acceleration and reversed engineered reducers for the application, be it a fresh project or a direct drop-in alternative to a competitor’s speed reducer. Fabricated metal reducers enable EP to complement a competitor’s footprint, centerline, and shaft elevation allowing a primary drop-in alternative saving the client time and money.
Long – Quiet Life
All worm gears in EP reducers are manufactured from phosphorous bronze. Our style also includes a hardened, floor and polished alloy steel worm. This mixture develops a smooth, work-hardened mating surface of the bronze equipment which enhances with prolonged service.
Worm gearing is a course of gear reducers that utilizes right angle, nonintersecting shafts. This form of reducer provides simple and quiet procedure and permits the likelihood of large quickness 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 compact design and building allows worm equipment reducers to be placed in a relatively small space. Thus, very high reductions in a restricted 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 weighty loads and shock loads. Worm gear drives offer 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 equipment reducer is one type of reduction gear container which includes a worm pinion input, an output worm gear, and features a right angle result orientation. This kind of reduction gear container is normally used to have a rated motor velocity and create a low speed result with higher torque worth based on the reduction ratio. They often 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 popular type of rate reducer because they provide the greatest speed decrease in the smallest package. With a high ratio of speed reduction and high torque output multiplier, it’s unsurprising that lots of power transmission systems utilize a worm gear reducer. Some of the most common 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 equipment 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 produced with tough 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 equipment reducers offer a choice of a solid or hollow output shaft and feature an adjustable mounting placement. Both the 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 referred to as worm gearbox or worm velocity reducers. Worm equipment reducers are used for speed decrease and increasing the torque for electrical motor drives. You can choose to mount your NEMA engine to the reducer by using the NEMA C encounter flange or use a coupling. If you want a coupling for the result 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 insight and shaft output. Interchangeable with most worm gear manufactures.

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 models are 56C or 145TC flange attach with either right, left or dual result shafts or a hollow bore result. The indirect drive versions are shaft input-shaft result boxes for make use of 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 gear reducers.
In order to decide on a gearbox speed reducer, you will have to determine the required torque and assistance factor for the application. Click on “Specifications” 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.
