worm gear speed reducer

Single reduction worm gearing offers high ratio reduction with few moving parts in a close-coupled compact drive. The right angle set up 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 arrangements adaptable to any mounting requirement. Efficient electric motor speeds are reduced to gradual 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 offers high efficiencies, and lengthy service existence. The hardened floor and polished alloy steel worm develops a smooth, work hardened surface area on the bronze equipment. For this reason worm gears put on in and improve with extented service while additional gears are wearing out. EP offers a wide collection of model configurations, sizes, ratios, and add-ons 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 apparatus applications) EP can offer fabricated steel housings with up to 48″ center distances. Fabricated housings provide optimum rigidity and strength that allows the transmission of higher horsepower levels than are possible with regular cast iron systems. Extra heavy side plates connect the worm and equipment shaft bearing supports, assuring correct meshing of the gear under all load circumstances. In smaller sized sizes, fabricated steel reducers are interchangeable with EP standard cast iron reducers.
Custom Designs
EP can provide custom swiftness and reversed engineered reducers for the application, be it a fresh project or a primary drop-in alternative to a competitor’s rate reducer. Fabricated steel reducers allow EP to match a competitor’s footprint, centerline, and shaft elevation allowing a direct drop-in alternative saving the client time and money.
Long – Quiet Life
All worm gears in EP reducers are produced from phosphorous bronze. Our style also incorporates a hardened, floor and polished alloy steel worm. This mixture develops a simple, work-hardened mating surface area of the bronze equipment which increases with prolonged service.
Worm gearing is a course of equipment reducers that utilizes right angle, nonintersecting shafts. This form of reducer provides simple and quiet operation and allows for the likelihood of large speed reductions. These gears are available from share in a wide variety of ratios, from only 4:1 to as much as 3600:1. The compact design and structure allows worm equipment reducers to be positioned in a comparatively small space. Thus, 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 the teeth. This increases the tolerance for weighty loads and shock loads. Worm gear drives provide 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 use worm gearing are: conveyors, mixers and bucket elevators.

A worm equipment reducer is one type of reduction gear package which includes a worm pinion input, an output worm equipment, and includes a right angle output orientation. This kind of reduction gear container is generally used to take a rated motor swiftness and produce a low speed result with higher torque worth based on the reduction ratio. They often can solve space-saving problems since the worm equipment reducer is among the sleekest decrease gearboxes available because of the small diameter of its result gear.
worm gear reducerWorm equipment reducers are also a favorite type of velocity reducer because they offer the greatest speed decrease in the smallest package. With a high 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 typical applications for worm gears can be found in tuning instruments, medical tests 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 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 produced with tough 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 a choice of a good or hollow output shaft and show an adjustable mounting placement. Both SW-1 and the SW-5, however, can withstand shock loading better than other reduction gearbox styles, making them well suited for demanding applications.

Worm Gear Reducers also known as worm gearbox or worm acceleration reducers. Worm gear reducers are used for speed reduction and increasing the torque for electric engine drives. You can decide to install your NEMA engine to the reducer utilizing the NEMA C encounter flange or use a coupling. If you want a coupling for the output or input shaft discover our coupling section for selecting a coupling. You can expect four assemblies left hand and right hand and double output shaft and shaft insight and shaft output. Interchangeable with the majority of worm gear manufactures.

EP DDVM series triple-reduction worm gear swiftness 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 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 are available in four configurations: horizontal, vertical, shafted, and shaft installed.
These reducers are perfect for water/waste-water gear drive applications such as thickeners and clarifiers, which require a vertical down shaft. Other available configurations also make EP triple reduction reducers perfect for use on mixers, elevators, solar power panels, astronomical telescopes, indexing tables, hoists, conveyors, or other process or materials handling systems where huge torques/sluggish speeds are needed.

Description
The HDR Series worm gear 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 mount with either right, left or dual result shafts or a hollow bore result. The indirect drive models are shaft input-shaft result boxes for make use of with sprocket or pulley drive systems. They offer an effective low cost solution to speed reduction and improved 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 assistance factor for the application form. Click on “Specifications” above for a desk that will aid in identifying the service factor. For service factors above 1.0, multiply the required torque by the provider factor.
