worm gear speed reducer
One reduction worm gearing offers high ratio reduction with few moving parts in a close-coupled small drive. The right angle arrangement 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 motor speeds are decreased to slower speed requirements of many industrial machines in a single reduction.

The exclusive use of the involute Helicoid Thread form (with departing side contact) on the worm and gear provides for high efficiencies, and long service life. The hardened floor and polished alloy steel worm develops a even, work hardened surface on the bronze equipment. Because of this worm gears put on in and improve with extented service while other gears are wearing out. Ever-Power offers a broad collection of model configurations, sizes, ratios, and components 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 gear applications) Ever-Power can offer fabricated steel housings with up to 48″ center distances. Fabricated housings provide optimum rigidity and strength that allows the tranny of higher horsepower amounts than are feasible with regular cast iron products. Extra heavy side plates connect the worm and gear shaft bearing supports, assuring correct meshing of the gear under all load conditions. In smaller sizes, fabricated metal reducers are interchangeable with Ever-Power regular cast iron reducers.
Custom Designs
Ever-Power can provide custom quickness and reversed engineered reducers for your application, be it a new project or a primary drop-in replacement for a competitor’s rate reducer. Fabricated metal reducers allow Ever-Power to match 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 manufactured from phosphorous bronze. Our design also includes a hardened, surface and polished alloy steel worm. This mixture develops a even, work-hardened mating surface area of the bronze gear which enhances with prolonged service.
Worm gearing is a course of gear reducers that utilizes correct angle, nonintersecting shafts. This style of reducer provides simple and quiet operation and permits the probability of large swiftness reductions. These gears can be found from share in a wide variety of ratios, from as low as 4:1 up to 3600:1. The small design and structure allows worm gear 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 equipment features the continuous sliding tooth action between worm and the teeth. This escalates the tolerance for weighty loads and shock loads. Worm gear drives provide 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 kind of reduction gear box which includes a worm pinion insight, an output worm gear, and includes a right angle output orientation. This kind of reduction gear container is normally used to have a rated motor acceleration and create a low speed result with higher torque value based on the decrease ratio. They often can solve space-saving problems because the worm gear reducer is among the sleekest decrease gearboxes available due to the small diameter of its output gear.
worm gear reducerWorm equipment reducers are also a popular type of speed 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 lots of power transmission systems utilize a worm equipment 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 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 tough compression-molded glass-fill up 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 solid or hollow output shaft and show an adjustable mounting position. Both the SW-1 and the SW-5, nevertheless, can endure shock loading much better than other reduction gearbox styles, making them perfect for demanding applications.

Worm Equipment Reducers also referred to as worm gearbox or worm acceleration reducers. Worm equipment reducers are used for speed decrease and raising the torque for electric powered motor drives. You can choose to attach your NEMA electric motor to the reducer by using the NEMA C encounter flange or use a coupling. If you want a coupling for the result or input shaft see our coupling section for selecting a coupling. We offer four assemblies left hands and right hands and double result shaft and shaft input and shaft result. Interchangeable with many worm gear manufactures.

Ever-Power DDVM series triple-reduction worm gear speed reducers can be found 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 pounds. 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 mounted.
These reducers are perfect for water/waste-water apparatus drive applications such as for example thickeners and clarifiers, which require a vertical down shaft. Other available configurations also make Ever-Power triple decrease reducers perfect for use on mixers, elevators, solar 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 reduce speeds and increase torque. Worm gear reducers are available in direct or indirect drive, direct drive models are 56C or 145TC flange attach with either right, still left or dual output shafts or a hollow bore result. The indirect drive versions are shaft input-shaft result boxes for make use of with sprocket or pulley drive systems. They provide 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 need to determine the mandatory torque and program factor for the application. Click on “Specifications” above for a desk that will aid in identifying the service element. For service elements above 1.0, multiply the mandatory torque by the assistance factor.
