worm gear speed reducer

Single reduction worm gearing provides high ratio reduction with few moving parts in a close-coupled compact drive. The right angle arrangement of driving-to-driven machine requires a minimum of space. Input and output shafts can be prolonged in either or both directions in horizontal or vertical arrangements adaptable to any mounting requirement. Efficient motor speeds are reduced to sluggish speed requirements of many industrial machines in a single reduction.

The exclusive utilization of the involute Helicoid Thread form (with departing side contact) on the worm and gear provides for high efficiencies, and lengthy service existence. The hardened floor and polished alloy metal worm develops a simple, work hardened surface on the bronze gear. For this reason worm gears use in and improve with prolonged service while various other gears are wearing out. Ever-Power offers a wide selection of model configurations, sizes, ratios, and add-ons from our standard product line.
Fabricated Designs
If your application involves serious shock loads or possible housing damage from external sources (as in steel mills or mobile products applications) Ever-Power can provide fabricated steel housings with up to 48″ center distances. Fabricated housings provide optimum rigidity and strength which allows the tranny of higher horsepower amounts than are possible with regular cast iron models. Extra heavy side plates connect the worm and equipment shaft bearing facilitates, assuring correct meshing of the gear under all load conditions. In smaller sizes, fabricated metal reducers are interchangeable with Ever-Power standard cast iron reducers.
Custom Designs
Ever-Power can provide custom quickness and reversed engineered reducers for your application, be it a new project or a primary drop-in alternative to a competitor’s swiftness reducer. Fabricated metal reducers enable Ever-Power to complement a competitor’s footprint, centerline, and shaft elevation allowing a direct drop-in alternative saving the customer time and money.
Long – Quiet Life
All worm gears in Ever-Power reducers are manufactured from phosphorous bronze. Our design also includes a hardened, surface and polished alloy metal worm. This mixture develops a smooth, work-hardened mating surface 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 soft and quiet procedure and allows for the probability of large swiftness reductions. These gears can be found from stock in a wide selection of ratios, from as low as 4:1 to as much as 3600:1. The small design and building allows worm equipment reducers to be placed in a comparatively small space. Thus, very high reductions in a restricted package size may be accomplished with this configuration. Our worm equipment features the constant sliding tooth actions between worm and the teeth. This escalates the tolerance for heavy loads and shock loads. Worm gear drives offer users high reducing capacity for relatively low cost when compared to 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.

-Housing:One time we casting creats great rigidity for severe impacts. Outer cooling fins and internal lubrication oil diversion channel style to improve heat dissipation.
-Worm Shaft: Manufactured with Carbon alloyed Metal S45C or SCM415, precison machined and carburized to HRC45 or HRC60, then 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 box which consists of a worm pinion insight, an output worm gear, and includes a right angle result orientation. This type of reduction gear container is normally used to take a rated motor quickness and create a low speed output with higher torque value based on the decrease ratio. They often can resolve space-saving problems since the worm gear reducer is one of the sleekest decrease gearboxes available due to the small diameter of its output gear.
worm gear reducerWorm equipment reducers are also a favorite type of rate reducer because they provide the greatest speed reduction in the tiniest package. With a high ratio of speed decrease and high torque output multiplier, it’s unsurprising that many 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 examining 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 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 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, noncorrosive, and nonmetallic.
Features
Our worm gear reducers offer an option of a solid or hollow output shaft and feature an adjustable mounting placement. Both the SW-1 and the SW-5, however, can withstand shock loading much better than other decrease gearbox designs, making them ideal for demanding applications.

Worm Gear Reducers also known as worm gearbox or worm acceleration reducers. Worm equipment reducers are used for speed decrease and increasing the torque for electric motor drives. You can choose to attach your NEMA motor to the reducer by using the NEMA C encounter flange or make use of a coupling. If you need a coupling for the result or input shaft find our coupling section for selecting a coupling. You can expect four assemblies left hand and right hands and double output shaft and shaft input and shaft output. Interchangeable with most worm gear manufactures. See data sheet in product overview for diamensions. If you don’t see your type, make sure you Contact Us.

Description
The HDR Series worm equipment reducers are used in low to moderate horsepower applications to lessen speeds and increase torque. Worm gear reducers can be found in direct or indirect drive, direct drive models are 56C or 145TC flange attach with either right, still left or dual output shafts or a hollow bore output. The indirect drive models are shaft input-shaft result boxes for use with sprocket or pulley drive systems. They offer an effective low cost 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 need to determine the mandatory torque and services factor for the application. Click on “Specs” above for a desk that will aid in determining the service element. For service elements above 1.0, multiply the required torque by the provider factor.
