worm gear speed reducer

Single reduction worm gearing offers high ratio reduction with couple of moving parts in a close-coupled compact drive. The proper angle arrangement 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 plans adaptable to any installation requirement. Efficient engine speeds are reduced to slower speed requirements of several 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 lifestyle. The hardened surface and polished alloy steel worm develops a simple, work hardened surface on the worm gear speed reducer bronze equipment. For this reason worm gears put on in and improve with extented service while additional gears are wearing out. Ever-Power offers a wide collection of model configurations, sizes, ratios, and add-ons 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 apparatus applications) Ever-Power can provide fabricated steel housings with up to 48″ center distances. Fabricated housings provide optimum rigidity and strength that allows the transmitting of higher horsepower levels than are feasible with standard cast iron systems. Extra heavy side plates connect the worm and equipment shaft bearing facilitates, assuring proper meshing of the gear under all load conditions. In smaller sized sizes, fabricated metal reducers are interchangeable with Ever-Power regular cast iron reducers.
Custom Designs
Ever-Power can offer custom swiftness and reversed engineered reducers for your application, be it a new project or a direct drop-in replacement for a competitor’s acceleration reducer. Fabricated steel reducers enable Ever-Power to complement a competitor’s footprint, centerline, and shaft elevation allowing a primary drop-in replacement 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, floor and polished alloy steel worm. This mixture develops a soft, work-hardened mating surface area of the bronze gear which increases with prolonged service.
Worm gearing is a course of equipment reducers that utilizes right angle, nonintersecting shafts. This form of reducer provides easy and quiet operation and permits the probability of large swiftness reductions. These gears are available from share in a wide variety of ratios, from only 4:1 up to 3600:1. The small design and structure allows worm equipment reducers to be placed in a comparatively small space. Thus, very high reductions in a limited package size can be achieved with this configuration. Our worm equipment features the constant sliding tooth actions between worm and the teeth. This increases the tolerance for weighty loads and shock loads. Worm gear drives provide users high reducing convenience of relatively low cost when compared to some 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.

A worm gear reducer is one kind of reduction gear container which consists of a worm pinion insight, an output worm equipment, and features a right angle output orientation. This kind of reduction gear box is normally used to have a rated motor speed and create a low speed result with higher torque value based on the decrease ratio. They often can resolve space-saving problems since the worm gear reducer is among the sleekest reduction gearboxes available because of the small diameter of its output gear.
worm gear reducerWorm equipment reducers are also a popular type of acceleration reducer because they offer the greatest speed reduction in the tiniest package. With a higher ratio of speed reduction 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 tests equipment, elevators, security gates, and conveyor belts.
SW-1 and SW-5
Torque Transmission provides two sizes of worm equipment 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 of these options are manufactured with durable compression-molded glass-fill polyester housings for a durable, long lasting, light-weight speed reducer that’s also compact, non-corrosive, and nonmetallic.
Features
Our worm equipment reducers offer a choice of a good or hollow output shaft and feature an adjustable mounting position. Both the SW-1 and the SW-5, nevertheless, can endure shock loading much better than other decrease gearbox designs, making them ideal for demanding applications.

Worm Gear Reducers also called worm gearbox or worm rate reducers. Worm gear reducers are used for speed decrease and raising the torque for electrical engine drives. You can decide to attach your NEMA electric motor to the reducer by using the NEMA C encounter flange or use 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 hand and right hands and double output shaft and shaft insight and shaft result. Interchangeable with the majority of 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 versions are 56C or 145TC flange mount with either right, still left or dual output shafts or a hollow bore result. The indirect drive models are shaft input-shaft output boxes for make use of with sprocket or pulley drive systems. They provide an effective low cost solution to speed reduction and improved 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 mandatory torque and service factor for the application form. Click on “Specs” above for a desk that will aid in identifying the service aspect. For service factors above 1.0, multiply the mandatory torque by the support factor.
