worm gear speed reducer

One reduction worm gearing provides high ratio reduction with couple of shifting parts in a close-coupled small drive. The proper angle set up of driving-to-driven machine requires a the least space. Input and output shafts can be extended in either or both directions in horizontal or vertical arrangements adaptable to any installation requirement. Efficient electric motor speeds are decreased to slower speed requirements of many industrial machines in one 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 lifestyle. The hardened surface and polished alloy steel worm develops a soft, work hardened surface area on the bronze equipment. For this reason worm gears use in and improve with prolonged service while other gears are deteriorating. worm gear speed reducer Ever-Power offers a wide collection of model configurations, sizes, ratios, and add-ons from our standard products.
Fabricated Designs
If your application involves serious shock loads or feasible housing damage from external sources (as in steel mills or mobile tools applications) Ever-Power can provide fabricated steel housings with up to 48″ center distances. Fabricated housings provide maximum rigidity and strength that allows the transmission of higher horsepower levels than are possible with standard cast iron devices. Extra heavy aspect plates connect the worm and gear shaft bearing supports, assuring proper meshing of the apparatus under all load circumstances. In smaller sizes, fabricated steel reducers are interchangeable with Ever-Power regular cast iron reducers.
Custom Designs
Ever-Power can provide custom velocity and reversed engineered reducers for your application, be it a new project or a primary drop-in replacement for a competitor’s speed reducer. Fabricated steel reducers allow Ever-Power to complement a competitor’s footprint, centerline, and shaft elevation allowing a primary drop-in alternative saving the client time and money.
Long – Quiet Life
All worm gears in Ever-Power reducers are produced from phosphorous bronze. Our style also incorporates a hardened, ground and polished alloy metal worm. This combination develops a simple, work-hardened mating surface area of the bronze gear which increases with prolonged service.
Worm gearing is a course of gear reducers that utilizes correct angle, nonintersecting shafts. This form of reducer provides easy and quiet operation and permits the possibility of large acceleration 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 compact design and construction allows worm equipment reducers to be positioned in a relatively small space. Thus, high reductions in a limited package size may be accomplished with this configuration. Our worm gear features the constant sliding tooth action between worm and the teeth. This increases the tolerance for weighty loads and shock loads. Worm gear drives offer users high reducing convenience of relatively low cost in comparison with 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 use worm gearing are: conveyors, mixers and bucket elevators.

A worm gear reducer is one type of reduction gear box which contains a worm pinion input, an output worm gear, and includes a right angle result orientation. This type of reduction gear box is generally used to take a rated motor speed and produce a low speed result with higher torque value based on the reduction ratio. They often times can resolve space-saving problems because the worm equipment reducer is among the sleekest reduction gearboxes available because of the small diameter of its result gear.
worm gear reducerWorm gear reducers are also a popular type of velocity reducer because they offer the greatest speed reduction in the smallest package. With a high ratio of speed decrease and high torque output multiplier, it’s unsurprising that lots of power transmission systems utilize a worm equipment reducer. Some of the most typical applications for worm gears can be found in tuning instruments, medical screening equipment, elevators, protection gates, and conveyor belts.
SW-1 and SW-5
Torque Transmission provides two sizes of worm equipment reducer, the SW-1 and the SW-5 and both are available 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 durable compression-molded glass-fill up polyester housings for a long lasting, 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 position. Both the SW-1 and the SW-5, nevertheless, can withstand shock loading better than other reduction gearbox designs, making them perfect for demanding applications.

Worm Gear Reducers also referred to as worm gearbox or worm acceleration reducers. Worm equipment reducers are used for speed decrease and raising the torque for electrical engine drives. You can decide to attach your NEMA engine to the reducer by using the NEMA C encounter flange or use a coupling. If you want a coupling for the output or input shaft observe our coupling section for selecting a coupling. We offer four assemblies left hand and right hand and double result shaft and shaft input and shaft output. Interchangeable with most 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 center distances from 7” to 20” (larger sizes available on request). Output torque ranges from 33,000 in lbs. for the 7” CD DDVM-70 to 582,900 in pounds 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 can be found in four configurations: horizontal, vertical, shafted, and shaft installed.
These reducers are ideal for water/waste-water equipment drive applications such as for example thickeners and clarifiers, which need a vertical straight down shaft. Other offered configurations also make Ever-Power triple decrease reducers perfect for make use of on mixers, elevators, solar power panels, astronomical telescopes, indexing tables, hoists, conveyors, or additional process or components handling systems where large torques/sluggish speeds are needed.

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 versions are 56C or 145TC flange mount with either right, remaining or dual result 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 provide an effective low priced solution to speed reduction and improved torque, with higher tolerances for shock loading than helical gear reducers.
In order to decide on a gearbox speed reducer, you will need to determine the mandatory torque and program factor for the application form. Click on “Specs” above for a desk that will assist in identifying the service factor. For service factors above 1.0, multiply the required torque by the support factor.
