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 requires a minimum of space. Input and result shafts can be extended in either or both directions in horizontal or vertical arrangements adaptable to any installation requirement. Efficient motor speeds are decreased to sluggish speed requirements of several industrial machines in a single reduction.

The exclusive utilization of the involute Helicoid Thread form (with departing side contact) on the worm and gear offers high efficiencies, and long service lifestyle. The hardened ground and polished alloy steel worm develops a smooth, work hardened surface on the bronze equipment. Because of this worm gears wear in and improve with prolonged service while other gears are deteriorating. Ever-Power offers a wide collection of model configurations, sizes, ratios, and accessories 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 products applications) Ever-Power can offer fabricated steel housings with up to 48″ center distances. Fabricated housings provide optimum rigidity and strength that allows the transmitting of higher horsepower amounts than are feasible with regular cast iron models. Extra heavy aspect plates connect the worm and gear shaft bearing facilitates, assuring correct meshing of the apparatus under all load circumstances. In smaller sizes, fabricated metal reducers are interchangeable with Ever-Power standard cast iron reducers.
Custom Designs
Ever-Power can provide custom speed and reversed engineered reducers for the application, be it a new project or a primary drop-in alternative to a competitor’s speed reducer. Fabricated steel reducers enable Ever-Power to complement a competitor’s footprint, centerline, and shaft elevation allowing a direct drop-in substitute 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 easy, work-hardened mating surface area of the bronze equipment which increases with prolonged service.
Worm gearing is a class of gear reducers that utilizes correct angle, nonintersecting shafts. This form of reducer provides clean and quiet procedure and allows for the likelihood of large swiftness reductions. These gears are available from stock in a wide variety of ratios, from only 4:1 up to 3600:1. The small design and construction allows worm equipment reducers to be positioned in a relatively small space. Thus, high reductions in a restricted package size can be achieved with this configuration. Our worm gear features the continuous sliding tooth action between worm and the teeth. This increases the tolerance for large loads and shock loads. Worm gear drives provide 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.
Ever-Power worm gear reducer gearbox series base on years of experiences uses designed teeth surface area with unsurpassed torque transfer functionality with great efficiency, efficency and cost.Worm gear system transmits power through sliding contact, resulting in extremely low vibration , noise, little backlash and self-locking property
-Housing:One time we casting creats great rigidity for serious impacts. Outer cooling fins and inner lubrication oil diversion channel design to improve 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 make sure 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 kind of reduction gear box which contains a worm pinion input, an output worm equipment, and features a right angle output orientation. This type of reduction gear package is generally used to have a rated motor velocity and create a low speed result with higher torque worth based on the decrease ratio. They often can solve space-saving problems since the worm equipment reducer is among the sleekest reduction gearboxes available due to the little diameter of its result gear.
worm gear reducerWorm gear reducers are also a favorite type of swiftness reducer because they provide the greatest speed decrease in the smallest package. With a higher ratio of speed decrease and high torque output multiplier, it’s unsurprising that lots of power transmission systems make use of a worm gear reducer. Some of the most common applications for worm gears are available in tuning instruments, medical testing equipment, elevators, security gates, and conveyor belts.
SW-1 and SW-5
Torque Transmission offers 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 these options are manufactured with rugged compression-molded glass-fill up polyester housings for a durable, long lasting, light weight speed reducer that’s also compact, non-corrosive, and nonmetallic.
Features
Our worm gear reducers offer a choice of a good or hollow output shaft and show an adjustable mounting position. Both the SW-1 and the SW-5, nevertheless, can endure shock loading much better than other decrease gearbox styles, making them perfect for demanding applications.

Worm Equipment Reducers also known as worm gearbox or worm acceleration reducers. Worm gear reducers are utilized for speed reduction and raising the torque for electrical electric motor drives. You can decide to install your NEMA motor to the reducer by using the NEMA C encounter flange or make use of a coupling. If you want a coupling for the output or input shaft observe our coupling section for selecting a coupling. You can expect four assemblies left hands and right hands and double result shaft and shaft input and shaft output. Interchangeable with most 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 can be found in direct or indirect drive, direct drive models are 56C or 145TC flange mount with either right, left or dual output shafts or a hollow bore result. The indirect drive versions are shaft input-shaft output boxes for use with sprocket or pulley drive systems. They provide an effective low priced solution to speed reduction and improved torque, with higher tolerances for shock loading than helical gear 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 “Specifications” above for a desk that will aid in identifying the service aspect. For service elements above 1.0, multiply the mandatory torque by the program factor.
