worm gear speed reducer
One reduction worm gearing offers high ratio reduction with few shifting parts in a close-coupled compact drive. The right angle arrangement of driving-to-driven machine takes a the least space. Input and result shafts can be prolonged in either or both directions in horizontal or vertical arrangements adaptable to any mounting requirement. Efficient motor speeds are decreased to slower speed requirements of several industrial machines in one reduction.

The exclusive usage of the involute Helicoid Thread form (with departing side contact) on the worm and gear offers high efficiencies, and lengthy service life. The hardened ground and polished alloy metal worm develops a even, work hardened surface on the bronze equipment. For this reason worm gears use in and improve with prolonged service while additional gears are wearing out. Ever-Power offers a broad collection of model configurations, sizes, ratios, and add-ons from our standard product line.
Fabricated Designs
If the application involves severe shock loads or feasible housing damage from external sources (as in steel mills or mobile equipment applications) Ever-Power can provide fabricated steel housings with up to a 48″ center distances. Fabricated housings provide maximum rigidity and strength that allows the transmitting of higher horsepower levels than are possible with standard cast iron products. Extra heavy part plates connect the worm and gear shaft bearing supports, assuring correct 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 offer custom swiftness and reversed engineered reducers for the application, be it a fresh project or a primary drop-in alternative to a competitor’s quickness reducer. Fabricated steel reducers enable Ever-Power to complement a competitor’s footprint, centerline, and shaft elevation allowing a primary 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 incorporates a hardened, ground and polished alloy metal worm. This mixture develops a smooth, work-hardened mating surface area of the bronze equipment which increases with prolonged service.
Worm gearing is a class of equipment reducers that utilizes correct angle, nonintersecting shafts. This form of reducer provides soft and quiet operation and allows for the probability of large speed reductions. These gears are available from stock in a wide selection of ratios, from only 4:1 to as much as 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 gear features the continuous sliding tooth actions between worm and one’s teeth. This escalates the tolerance for weighty loads and shock loads. Worm gear drives offer users high reducing convenience of relatively low cost when compared to 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.

A worm gear reducer is one kind of reduction gear box which consists of a worm pinion input, an output worm gear, and features a right angle output orientation. This type of reduction gear package is generally used to take a rated motor quickness and create a low speed output with higher torque worth based on the decrease ratio. They often can resolve space-saving problems because the worm equipment reducer is among the sleekest reduction gearboxes available due to the small diameter of its output gear.
worm gear reducerWorm gear reducers are also a popular type of swiftness 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 examining 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 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 produced with rugged compression-molded glass-fill polyester housings for a durable, long lasting, light weight speed reducer that is also compact, non-corrosive, and nonmetallic.
Features
Our worm gear reducers offer an option of a good or hollow output shaft and feature an adjustable mounting position. Both the SW-1 and the SW-5, however, can withstand shock loading much better than other reduction gearbox styles, making them perfect for demanding applications.

Worm Equipment Reducers also known as worm gearbox or worm rate reducers. Worm equipment reducers are utilized for speed reduction and increasing the torque for electric electric motor drives. You can choose to install your NEMA electric motor to the reducer by using the NEMA C face flange or use a coupling. If you need a coupling for the output or input shaft discover our coupling section for selecting a coupling. We offer four assemblies left hand and right hands and double result shaft and shaft input and shaft output. Interchangeable with many worm gear manufactures.

Ever-Power DDVM series triple-reduction worm gear velocity reducers can be found in ratios from 5000:1 to 175,000:1 and middle distances from 7” to 20” (larger sizes 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 devices drive applications such as for example thickeners and clarifiers, which require a vertical down shaft. Other obtainable configurations also make Ever-Power triple reduction reducers perfect for use on mixers, elevators, solar panels, astronomical telescopes, indexing tables, hoists, conveyors, or additional process or components handling systems where huge torques/slower speeds are needed.
These reducers are also available with a helical main reduction stage and are termed the HDVM series

Description
The HDR Series worm equipment reducers are found in low to moderate horsepower applications to lessen 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 result. 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 decrease 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 required torque and program factor for the application. Click on “Specs” above for a table that will assist in identifying the service aspect. For service factors above 1.0, multiply the required torque by the support factor.
