worm gear speed reducer
Solitary reduction worm gearing offers high ratio reduction with few shifting parts in a close-coupled compact drive. The right angle set up of driving-to-driven machine takes a minimum of space. Input and output shafts can be extended in either or both directions in horizontal or vertical plans adaptable to any mounting requirement. Efficient electric motor speeds are reduced to sluggish 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 existence. The hardened floor and polished alloy metal worm develops a clean, work hardened surface area on the bronze equipment. Because of this worm gears wear in and improve with prolonged service while additional gears are deteriorating. Ever-Power offers a broad selection of model configurations, sizes, ratios, and accessories from our standard product line.
Fabricated Designs
If the application involves severe shock loads or possible housing damage from external sources (as in steel mills or mobile devices applications) Ever-Power can provide fabricated steel housings with up to a 48″ center distances. Fabricated housings provide optimum rigidity and strength which allows the tranny of higher horsepower amounts than are feasible with regular cast iron devices. Extra heavy side plates connect the worm and gear shaft bearing facilitates, assuring proper meshing of the gear under all load circumstances. In smaller sized sizes, fabricated metal reducers are interchangeable with Ever-Power regular cast iron reducers.
Custom Designs
Ever-Power can offer custom velocity and reversed engineered reducers for your application, be it a fresh project or a direct drop-in alternative to a competitor’s quickness reducer. Fabricated steel reducers enable Ever-Power to complement a competitor’s footprint, centerline, and shaft height allowing a direct drop-in substitute saving the customer 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 combination develops a soft, work-hardened mating surface of the bronze gear which increases 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 operation and permits the possibility of large speed reductions. These gears can be found from stock in a wide variety of ratios, from only 4:1 to as much as 3600:1. The small design and construction allows worm equipment reducers to be placed in a relatively small space. Thus, very high reductions in a restricted package size can be achieved with this configuration. Our worm gear features the continuous sliding tooth action between worm and one’s teeth. This escalates the tolerance for large loads and shock loads. Worm gear drives provide 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.

A worm gear reducer is one type of reduction gear package which contains a worm pinion input, an output worm equipment, and features a right angle result orientation. This type of reduction gear container is normally used to have a rated motor velocity and create a low speed output with higher torque value based on the reduction ratio. They often can solve space-saving problems because the worm equipment reducer is one of 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 rate reducer because they offer the greatest speed reduction in the tiniest package. With a higher ratio of speed reduction and high torque output multiplier, it’s unsurprising that lots of power transmission systems utilize a worm equipment 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 equipment reducer, the SW-1 and the SW-5 and both can be found 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 tough compression-molded glass-fill polyester housings for a long lasting, long lasting, light weight speed reducer that is also compact, non-corrosive, and nonmetallic.
Features
Our worm equipment reducers offer an option of a solid or hollow result shaft and feature an adjustable mounting position. Both the SW-1 and the SW-5, however, can endure shock loading much better than other reduction gearbox designs, making them well suited for demanding applications.

Worm Gear Reducers also referred to as worm gearbox or worm speed reducers. Worm gear reducers are used for speed reduction and raising the torque for electric motor drives. You can decide to mount your NEMA engine to the reducer utilizing the NEMA C encounter flange or make use of a coupling. If you need a coupling for the output or input shaft discover 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 output. Interchangeable with the majority of 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 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 input 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 are available in four configurations: horizontal, vertical, shafted, and shaft installed.
These reducers are ideal 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 power panels, astronomical telescopes, indexing tables, hoists, conveyors, or various other process or materials handling systems where large torques/slow 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 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 install with either right, remaining or dual result shafts or a hollow bore result. The indirect drive versions 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 have to determine the required torque and services factor for the application form. Click on “Specs” above for a table that will aid in determining the service element. For service elements above 1.0, multiply the mandatory torque by the program factor.
