worm gear speed reducer

Single reduction worm gearing offers 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 extended in either or both directions in horizontal or vertical arrangements adaptable to any mounting requirement. Efficient engine speeds are reduced to slow speed requirements of many industrial machines in a single 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 ground and polished alloy metal worm develops a simple, work hardened surface on the bronze gear. Because of this worm gears put on in and improve with prolonged service while additional gears are deteriorating. Ever-Power offers a wide selection of model configurations, sizes, ratios, and accessories from our standard product line.
Fabricated Designs
If the application involves serious shock loads or possible housing damage from external sources (as in steel mills or mobile tools applications) Ever-Power can offer fabricated steel housings with up to 48″ center distances. Fabricated housings provide optimum rigidity and strength which allows the tranny of higher horsepower levels than are possible with standard cast iron devices. Extra heavy part plates connect the worm and equipment shaft bearing facilitates, assuring correct meshing of the apparatus under all load circumstances. In smaller sizes, fabricated steel reducers are interchangeable with Ever-Power standard cast iron reducers.
Custom Designs
Ever-Power can offer custom quickness and reversed engineered reducers for your application, be it a new project or a direct drop-in alternative to a competitor’s quickness reducer. Fabricated metal reducers enable Ever-Power to match a competitor’s footprint, centerline, and shaft height allowing a direct drop-in substitute saving the client time and money.
Long – Quiet Life
All worm gears in Ever-Power reducers are produced from phosphorous bronze. Our style also includes a hardened, floor and polished alloy steel worm. This combination develops a even, work-hardened mating surface of the bronze gear which enhances with prolonged service.
Worm gearing is a course of equipment reducers that utilizes right angle, nonintersecting shafts. This form of reducer provides clean and quiet operation and permits the likelihood of large rate reductions. These gears can be found from share in a wide selection of ratios, from only 4:1 up to 3600:1. The small design and building allows worm gear reducers to be placed in a comparatively small space. Thus, very high reductions in a limited package size may be accomplished with this configuration. Our worm gear features the constant sliding tooth action between worm and the teeth. This escalates the tolerance for weighty loads and shock loads. Worm gear drives provide users high reducing capacity for 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 use worm gearing are: conveyors, mixers and bucket elevators.
Ever-Power worm gear reducer gearbox series base on years of experiences uses designed teeth surface with unsurpassed torque transfer overall performance with great efficiency, efficency and cost.Worm gear system transmits power through sliding contact, leading to extremely low vibration , noise, little worm gear speed reducer backlash and self-locking property
-Housing:One time we casting creats great rigidity for serious impacts. Outer cooling fins and internal lubrication oil diversion channel design to increase heat dissipation.
-Worm Shaft: Manufactured with Carbon alloyed Metal 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 equipment reducer is one kind of reduction gear container which includes a worm pinion insight, an output worm gear, and includes 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 output with higher torque value based on the decrease ratio. They often times can solve space-saving problems since the worm equipment reducer is one of the sleekest reduction gearboxes available because of the little diameter of its result gear.
worm gear reducerWorm gear reducers are also a favorite type of rate reducer because they offer the greatest speed decrease in the tiniest package. With a higher ratio of speed decrease and high torque result multiplier, it’s unsurprising that many power transmission systems utilize a worm equipment reducer. Some of the most typical applications for worm gears can be found in tuning instruments, medical testing 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 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 of these options are produced with rugged compression-molded glass-fill polyester housings for a durable, long lasting, light weight speed reducer that’s also compact, noncorrosive, and nonmetallic.
Features
Our worm gear reducers offer an option of a good 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 swiftness reducers. Worm gear reducers are used for speed reduction and increasing the torque for electrical electric motor drives. You can decide to attach your NEMA motor to the reducer by using the NEMA C encounter flange or use a coupling. If you need a coupling for the output or input shaft observe our coupling section for selecting a coupling. We offer four assemblies left hands and right hands and double output shaft and shaft input and shaft result. Interchangeable with most 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, still left or dual output shafts or a hollow bore output. 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 increased torque, with higher tolerances for shock loading than helical gear reducers.
In order to select a gearbox speed reducer, you will have to determine the mandatory torque and service factor for the application form. Click on “Specifications” above for a desk that will aid in determining the service element. For service factors above 1.0, multiply the required torque by the support factor.
