worm gear speed reducer
One reduction worm gearing offers high ratio reduction with couple of shifting parts in a close-coupled compact drive. The right 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 mounting requirement. Efficient electric motor speeds are decreased to slower speed requirements of several industrial machines in a single reduction.

The exclusive use of the involute Helicoid Thread form (with departing side contact) on the worm and gear provides for high efficiencies, and long service life. 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 extented service while other gears are wearing out. Ever-Power offers a wide selection of model configurations, sizes, ratios, and add-ons 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 apparatus applications) Ever-Power can offer fabricated steel housings with up to a 48″ center distances. Fabricated housings provide optimum rigidity and strength that allows the transmitting of higher horsepower levels than are feasible with regular cast iron systems. Extra heavy aspect plates connect the worm and gear shaft bearing facilitates, assuring appropriate meshing of the apparatus under all load conditions. In smaller sizes, fabricated steel reducers are interchangeable with Ever-Power regular 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 direct drop-in replacement for a competitor’s speed reducer. Fabricated metal reducers enable Ever-Power to match a competitor’s footprint, centerline, and shaft height allowing a primary 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, ground and polished alloy steel worm. This combination develops a even, work-hardened mating surface of the bronze gear which boosts with prolonged service.
Worm gearing is a class of equipment reducers that utilizes correct angle, nonintersecting shafts. This form of reducer provides simple and quiet procedure and allows for the probability of large acceleration reductions. These gears can be found from share in a wide selection of ratios, from as low as 4:1 up to 3600:1. The compact design and building allows worm equipment reducers to be positioned in a comparatively small space. Thus, very high reductions in a limited package size can be achieved with this configuration. Our worm gear features the continuous sliding tooth action between worm and one’s 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 use 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 type of reduction gear package which consists of a worm pinion input, an output worm gear, and includes a right angle result orientation. This kind of reduction gear package is normally used to have a rated motor acceleration and create a low speed output with higher torque value based on the decrease ratio. They often times can resolve space-saving problems because the worm gear reducer is among the sleekest decrease gearboxes available due to the little diameter of its result gear.
worm gear reducerWorm gear reducers are also a favorite type of rate 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 many power transmission systems utilize a worm gear reducer. Some of the most common applications for worm gears are available in tuning instruments, medical tests equipment, elevators, protection gates, and conveyor belts.
SW-1 and SW-5
Torque Transmission offers two sizes of worm equipment 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 up polyester housings for a durable, long lasting, light-weight speed reducer that’s also compact, noncorrosive, and nonmetallic.
Features
Our worm gear reducers offer a choice of a solid or hollow output shaft and show an adjustable 
mounting placement. Both the SW-1 and the SW-5, nevertheless, can withstand shock loading much better than other reduction gearbox designs, making them well suited for demanding applications.

Worm Equipment Reducers also referred to as worm gearbox or worm acceleration reducers. Worm equipment reducers are utilized for speed decrease and raising the torque for electric powered motor drives. You can choose to install your NEMA electric motor to the reducer utilizing the NEMA C face flange or make use of a coupling. If you need a coupling for the output 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.

Ever-Power DDVM series triple-reduction worm gear acceleration reducers can be found in ratios from 5000:1 to 175,000:1 and middle distances from 7” to 20” (larger sizes available on request). Result torque ranges from 33,000 in lbs. for the 7” CD DDVM-70 to 582,900 in lbs for the DDVM-200. Mechanical HP insight requirements are from 0.09 HP for the 175,000:1 7 in CD reducer to 6.25 HP for the 5000:1 20” CD unit. These reducers can be found in four configurations: horizontal, vertical, shafted, and shaft installed.
These reducers are well suited for water/waste-water tools drive applications such as for example thickeners and clarifiers, which require a vertical straight down shaft. Other offered configurations also make Ever-Power triple reduction reducers perfect for use on mixers, elevators, solar panels, astronomical telescopes, indexing tables, hoists, conveyors, or other process or materials handling systems where huge torques/sluggish speeds are needed.
These reducers are also offered with a helical main reduction stage and so are termed the HDVM series

Description
The HDR Series worm equipment reducers are used in low to moderate horsepower applications to reduce speeds and increase torque. Worm gear reducers are available 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 models are shaft input-shaft result boxes for make use of with sprocket or pulley drive systems. They provide an effective low cost solution to speed reduction and increased torque, with higher tolerances for shock loading than helical equipment reducers.
In order to decide on a gearbox speed reducer, you will need to determine the required torque and provider factor for the application form. Click on “Specifications” above for a table that will aid in identifying the service aspect. For service factors above 1.0, multiply the mandatory torque by the assistance factor.
