worm gear speed reducer
Single reduction worm gearing provides high ratio reduction with few moving parts in a close-coupled small drive. The proper angle arrangement of driving-to-driven machine takes a the least space. Input and output shafts can be extended in either or both directions in horizontal or vertical plans adaptable to any mounting requirement. Efficient engine speeds are decreased to slow speed requirements of many industrial machines in one reduction.

The exclusive usage of the involute Helicoid Thread form (with leaving side contact) on the worm and gear offers high efficiencies, and long service lifestyle. The hardened surface and polished alloy metal worm develops a easy, work hardened surface area on the bronze gear. For this reason worm gears wear in and improve with prolonged service while other gears are deteriorating. Ever-Power offers a broad selection of model configurations, sizes, ratios, and accessories from our standard product line.
Fabricated Designs
If your application involves serious shock loads or feasible housing damage from external sources (as in steel mills or mobile products 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 units. Extra heavy aspect plates connect the worm and gear shaft bearing facilitates, assuring correct meshing of the gear under all load conditions. In smaller sized sizes, fabricated metal reducers are interchangeable with Ever-Power standard 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 primary drop-in alternative to a competitor’s rate reducer. Fabricated steel reducers enable Ever-Power to match a competitor’s footprint, centerline, and shaft height allowing a primary drop-in replacement 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 steel worm. This mixture develops a simple, work-hardened mating surface of the bronze equipment which enhances with prolonged service.
Worm gearing is a course of gear reducers that utilizes right angle, nonintersecting shafts. This style of reducer provides smooth and quiet procedure and allows for the possibility of large acceleration reductions. These gears are available from share in a wide selection of ratios, from only 4:1 up to 3600:1. The compact design and construction allows worm equipment reducers to be positioned in a comparatively small space. Thus, very high reductions in a restricted package size can be achieved with this configuration. Our worm equipment features the continuous sliding tooth action between worm and one’s teeth. This increases the tolerance for large loads and shock loads. Worm gear drives offer users high reducing capacity for relatively low cost when compared to some 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.

A worm gear reducer is one type of reduction gear container which includes a worm pinion insight, an output worm gear, and features a right angle output orientation. This type of reduction gear box is generally used to have a rated motor rate and produce a low speed output with higher torque worth based on the decrease ratio. They often times can solve space-saving problems since the worm equipment reducer is among the sleekest reduction gearboxes available due to the small diameter of its result gear.
worm gear reducerWorm equipment reducers are also a popular type of velocity reducer because they offer the greatest speed decrease in the smallest package. With a high ratio of speed decrease and high torque output multiplier, it’s unsurprising that many power transmission systems utilize a worm gear reducer. Some of the most typical applications for worm gears are available in tuning instruments, medical assessment equipment, elevators, protection 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 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 of these options are manufactured with durable compression-molded glass-fill up polyester housings for a long lasting, long lasting, light-weight speed reducer that is also compact, non-corrosive, and nonmetallic.
Features
Our worm gear reducers offer a choice of a good or hollow result shaft and show an adjustable mounting position. Both SW-1 and the SW-5, nevertheless, can withstand shock loading better than other decrease gearbox designs, making them ideal for demanding applications.

Worm Gear Reducers also referred to as worm gearbox or worm velocity reducers. Worm equipment reducers are used for speed reduction and raising the torque for electrical electric motor drives. You can decide to install your NEMA electric motor to the reducer by using the NEMA C encounter flange or use a coupling. If you need 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 hands and double output shaft and shaft insight and shaft result. Interchangeable with most worm gear manufactures.

Ever-Power DDVM series triple-reduction worm gear quickness reducers are available in ratios from 5000:1 to 175,000:1 and center 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 pounds 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 ideal for water/waste-water apparatus drive applications such as thickeners and clarifiers, which need a vertical down shaft. Other available configurations also make Ever-Power triple decrease reducers perfect for make use of on mixers, elevators, solar panels, astronomical telescopes, indexing tables, hoists, conveyors, or various other process or components handling systems where large torques/slow speeds are needed.
These reducers are also offered with a helical primary reduction stage and so are termed the HDVM series

Description
The HDR Series worm gear reducers are found 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 install with either right, left or dual result shafts or a hollow bore output. The indirect drive models are shaft input-shaft output boxes for use with sprocket or pulley drive systems. They provide an effective low priced 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 need to determine the mandatory 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 service factor.
