worm gear speed reducer
One reduction worm gearing provides high ratio reduction with few moving parts in a close-coupled small drive. The proper angle set up 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 slower speed requirements of many industrial machines in one reduction.

The exclusive utilization of the involute Helicoid Thread form (with leaving side contact) on the worm and gear provides for high efficiencies, and long service existence. The hardened floor and polished alloy metal worm develops a clean, work hardened surface on the bronze equipment. Because of this worm gears put on in and improve with extented service while additional gears are wearing out. Ever-Power offers a broad collection of model configurations, sizes, ratios, and add-ons from our standard products.
Fabricated Designs
If your application involves severe shock loads or feasible housing damage from external sources (as in steel mills or mobile equipment applications) Ever-Power can provide fabricated steel housings with up to 48″ center distances. Fabricated housings provide maximum rigidity and strength that allows the transmission of higher horsepower levels than are feasible with regular cast iron devices. Extra heavy part plates connect the worm and equipment shaft bearing facilitates, assuring proper meshing of the apparatus under all load conditions. In smaller sizes, fabricated steel reducers are interchangeable with Ever-Power standard cast iron reducers.
Custom Designs
Ever-Power can provide custom acceleration and reversed engineered reducers for your application, be it a new project or a direct drop-in replacement for a competitor’s rate reducer. Fabricated metal reducers allow Ever-Power to complement a competitor’s footprint, centerline, and shaft elevation allowing a direct drop-in replacement saving the customer time and money.
Long – Quiet Life
All worm gears in Ever-Power reducers are produced from phosphorous bronze. Our style also includes a hardened, surface and polished alloy metal worm. This mixture develops a clean, work-hardened mating surface area of the bronze gear which enhances with prolonged service.
Worm gearing is a class of equipment reducers that utilizes correct angle, nonintersecting shafts. This form of reducer provides simple and quiet operation and allows for the possibility of large speed reductions. These gears can be found from share in a wide variety of ratios, from only 4:1 up to 3600:1. The compact design and construction allows worm equipment reducers to be positioned in a comparatively small space. Thus, very high reductions in a restricted package size can be achieved with this configuration. Our worm gear features the constant sliding tooth action between worm and one’s teeth. This escalates 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 use 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 gear reducer is one type of reduction gear box which consists of a worm pinion insight, an output worm equipment, and includes a right angle result orientation. This kind of reduction gear container is generally used to take a rated motor velocity and produce a low speed output with higher torque worth based on the decrease ratio. They often can resolve space-saving problems because the worm gear reducer is among the sleekest reduction gearboxes available due to the small diameter of its result gear.
worm gear reducerWorm gear reducers are also a favorite type of swiftness reducer because they offer the greatest speed reduction in the tiniest package. With a high ratio of speed decrease and high torque output multiplier, it’s unsurprising that lots of power transmission systems utilize a worm gear reducer. Some of the most typical applications for worm gears can be found in tuning instruments, medical testing 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 are available 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 tough compression-molded glass-fill up 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 good or hollow result shaft and feature an adjustable mounting position. Both SW-1 and the SW-5, nevertheless, can endure shock loading better than other reduction gearbox designs, making them ideal for demanding applications.

Worm Gear Reducers also known as worm gearbox or worm acceleration reducers. Worm gear reducers are used for speed reduction and increasing the torque for electric motor drives. You can decide to mount your NEMA electric motor to the reducer utilizing the NEMA C face flange or use a coupling. If you need a coupling for the output or input shaft see our coupling section for selecting a coupling. You can expect four assemblies left hand and right hand and double output shaft and shaft input and shaft result. Interchangeable with many worm gear manufactures.

Description
The HDR Series worm gear 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 install with either right, remaining or dual output shafts or a hollow bore result. 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 cost solution to speed decrease and improved 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 required torque and assistance factor for the application. Click on “Specs” above for a desk that will assist in identifying the service factor. For service factors above 1.0, multiply the mandatory torque by the assistance factor.
