One reduction worm gearing provides high ratio reduction with few shifting parts in a close-coupled small drive. The proper angle set up of driving-to-driven machine takes a the least space. Input and output shafts can be extended in either or both directions in horizontal or vertical plans adaptable to any mounting requirement. Efficient engine speeds are reduced to slower speed requirements of several industrial machines in a single reduction.

The exclusive utilization of the involute Helicoid Thread form (with leaving side contact) on the worm and gear offers high efficiencies, and lengthy service existence. The hardened ground and polished alloy metal worm develops a simple, work hardened surface area on the bronze equipment. Because of this worm gears use in and improve with prolonged service while other gears are deteriorating. Ever-Power offers a broad selection of model configurations, sizes, ratios, and components 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 equipment applications) Ever-Power can offer fabricated steel housings with up to 48″ center distances. Fabricated housings provide optimum rigidity and strength which allows the transmitting of higher horsepower levels than are feasible with standard cast iron units. Extra heavy side plates connect the worm and gear shaft bearing facilitates, assuring correct meshing of the gear under all load conditions. In smaller sizes, fabricated metal reducers are interchangeable with Ever-Power regular cast iron reducers.
Custom Designs
Ever-Power can provide custom velocity and reversed engineered reducers for the application, be it a fresh project or a direct drop-in replacement for a competitor’s velocity reducer. Fabricated metal reducers enable Ever-Power 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 Ever-Power reducers are produced from phosphorous bronze. Our design also includes a hardened, floor and polished alloy metal worm. This mixture develops a simple, work-hardened mating surface area of the bronze gear which boosts with prolonged service.
Worm gearing is a class of gear reducers that utilizes correct angle, nonintersecting shafts. This form of reducer provides smooth and quiet procedure and permits the likelihood of large velocity reductions. These gears can be found from share in a wide selection of ratios, from only 4:1 to as much as 3600:1. The compact design and building allows worm gear reducers to be placed in a relatively small space. Thus, high reductions in a restricted package size can be achieved with this configuration. Our worm equipment features the constant sliding tooth actions between worm and the teeth. This escalates the tolerance for weighty loads and shock loads. Worm gear drives offer users high reducing capacity for relatively low cost when compared to 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.

-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 kind of reduction gear container which consists of a worm pinion input, an output worm gear, and includes a right angle output orientation. This type of reduction gear package is generally used to take a rated motor speed and produce a low speed output with higher torque value based on the reduction ratio. They often times can solve space-saving problems because the worm equipment reducer is among the sleekest reduction gearboxes available because of the little diameter of its output gear.
worm gear reducerWorm equipment reducers are also a popular 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 output multiplier, it’s unsurprising that many power transmission systems utilize a worm gear reducer. Some of the most typical applications for worm gears are available in tuning instruments, medical assessment 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 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 tough compression-molded glass-fill up polyester housings for a long lasting, long lasting, light weight speed reducer that’s 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 position. Both the SW-1 and the SW-5, however, can withstand shock loading better than other decrease gearbox designs, making them ideal for demanding applications.

Worm Gear Reducers also known as worm gearbox or worm swiftness reducers. Worm gear reducers are utilized for speed decrease and increasing the torque for electric electric motor drives. You can choose to attach your NEMA engine to the reducer utilizing the NEMA C face flange or use a coupling. If you need a coupling for the result or input shaft observe our coupling section for choosing the coupling. You can expect four assemblies left hand and right hand and double output shaft and shaft input and shaft output. Interchangeable with many worm gear manufactures. See data sheet in product overview for diamensions. If you don’t see your type, make sure you Contact Us.

Description
The HDR Series worm gear reducers are found in low to moderate horsepower applications to lessen 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, still left or dual result shafts or a hollow bore result. The indirect drive versions are shaft input-shaft result boxes for use with sprocket or pulley drive systems. They provide 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 have to determine the required torque and assistance factor for the application. Click on “Specifications” above for a desk that will aid in determining the service aspect. For service factors above 1.0, multiply the mandatory torque by the service factor.
