Solitary reduction worm gearing provides high ratio reduction with couple of shifting parts in a close-coupled small drive. The right angle set up of driving-to-driven machine requires a the least space. Input and result shafts can be prolonged in either or both directions in horizontal or vertical arrangements adaptable to any installation requirement. Efficient electric motor speeds are decreased to slow speed requirements of several industrial machines in a single reduction.

The exclusive usage of the involute Helicoid Thread form (with leaving side contact) on the worm and gear provides for high efficiencies, and lengthy service existence. The hardened surface and polished alloy steel worm develops a soft, work hardened surface on the bronze equipment. Because of this worm gears put on in and improve with prolonged service while various other gears are wearing out. Ever-Power offers a broad selection of model configurations, sizes, ratios, and add-ons from our standard product line.
Fabricated Designs
If the application involves serious shock loads or feasible housing damage from external sources (as in steel mills or mobile gear applications) Ever-Power can provide fabricated steel housings with up to 48″ center distances. Fabricated housings provide optimum rigidity and strength that allows the transmission of higher horsepower levels than are feasible with standard cast iron devices. Extra heavy part plates connect the worm and gear shaft bearing facilitates, assuring proper 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 offer custom rate and reversed engineered reducers for the application, be it a fresh project or a primary drop-in replacement for a competitor’s speed reducer. Fabricated metal reducers allow Ever-Power to complement a competitor’s footprint, centerline, and shaft elevation allowing a direct drop-in substitute saving the client time and money.
Long – Quiet Life
All worm gears in Ever-Power reducers are manufactured from phosphorous bronze. Our style also includes a hardened, ground and polished alloy steel worm. This mixture develops a smooth, work-hardened mating surface area of the bronze equipment which improves with prolonged service.
Worm gearing is a course of equipment reducers that utilizes right angle, nonintersecting shafts. This form of reducer provides smooth and quiet procedure and permits the probability of large quickness reductions. These gears are available from share in a wide variety of ratios, from as low as 4:1 up to 3600:1. The compact design and building allows worm gear reducers to be placed in a comparatively small space. Thus, 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 one’s 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 utilization 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 foundation on years of experiences uses designed teeth surface with unsurpassed torque transfer functionality with great performance, efficency and cost.Worm gear program transmits power through sliding contact, leading to extremely low vibration , noise, little backlash and self-locking property

A worm gear reducer is one type of reduction gear package which includes a worm pinion input, an output worm gear, and includes a right angle result orientation. This type of reduction gear package is normally used to take a rated motor swiftness and produce a low speed result with higher torque value based on the decrease ratio. They often can solve space-saving problems because the worm equipment reducer is one of the sleekest decrease gearboxes available due to the little diameter of its result gear.
worm gear reducerWorm equipment reducers are also a favorite type of velocity reducer because they provide the greatest speed decrease in the tiniest package. With a higher 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 typical applications for worm gears are available 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 these options are manufactured with durable compression-molded glass-fill polyester housings for a long lasting, long lasting, light weight speed reducer that is also compact, noncorrosive, and nonmetallic.
Features
Our worm gear reducers offer an option of a solid or hollow result shaft and feature an adjustable mounting placement. Both SW-1 and the SW-5, nevertheless, can withstand shock loading much better than other decrease gearbox designs, making them perfect for demanding applications.

Worm Gear Reducers also known as worm gearbox or worm velocity reducers. Worm equipment reducers are utilized for speed reduction and raising the torque for electric electric motor drives. You can choose to attach your NEMA electric motor to the reducer utilizing the NEMA C face flange or use a coupling. If you want a coupling for the result or input shaft see our coupling section for choosing the coupling. You can expect four assemblies left hand and right hand and double output shaft and shaft insight and shaft result. Interchangeable with many worm gear manufactures. See data sheet in product overview for diamensions. Unless you see your type, please Contact Us.

Description
The HDR Series worm gear reducers are used in low to moderate horsepower applications to lessen speeds and increase torque. Worm gear reducers are available in direct or indirect drive, direct drive versions are 56C or 145TC flange attach with either right, remaining or dual output 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 offer an effective low cost solution to speed decrease 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 provider factor for the application. Click on “Specs” above for a desk that will aid in identifying the service factor. For service factors above 1.0, multiply the mandatory torque by the support factor.
