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 takes a minimum of space. Input and result shafts can be prolonged in either or both directions in horizontal or vertical plans adaptable to any installation requirement. Efficient electric motor speeds are decreased to slow 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 lifestyle. The hardened ground and polished alloy metal worm develops a simple, work hardened surface area on the bronze equipment. For this reason worm gears wear in and improve with prolonged service while other gears are wearing out. Ever-Power offers a broad selection of model configurations, sizes, ratios, and components from our standard product line.
Fabricated Designs
If the application involves serious shock loads or feasible housing damage from external sources (as in steel mills or mobile apparatus applications) Ever-Power can offer fabricated steel housings with up to a 48″ center distances. Fabricated housings provide maximum rigidity and strength which allows the tranny of higher horsepower levels than are feasible with regular cast iron systems. Extra heavy side plates connect the worm and gear shaft bearing supports, assuring correct meshing of the apparatus under all load conditions. In smaller sizes, fabricated steel reducers are interchangeable with Ever-Power standard cast iron reducers.
Custom Designs
Ever-Power can offer custom swiftness and reversed engineered reducers for the application, be it a new project or a direct drop-in replacement for a competitor’s speed reducer. Fabricated steel reducers enable Ever-Power to complement a competitor’s footprint, centerline, and shaft elevation allowing a direct drop-in substitute saving the client time and money.
Long – Quiet Life
All worm gears in Ever-Power reducers are produced from phosphorous bronze. Our design also incorporates a hardened, surface and polished alloy steel worm. This mixture develops a soft, work-hardened mating surface of the bronze gear which increases with prolonged service.
Worm gearing is a class of gear reducers that utilizes correct angle, nonintersecting shafts. This style of reducer provides clean and quiet operation and allows for the likelihood of large acceleration reductions. These gears are available from share in a wide selection of ratios, from as low as 4:1 up to 3600:1. The compact design and structure 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 constant sliding tooth action between worm and one’s teeth. This escalates the tolerance for weighty loads and shock loads. Worm gear drives provide users high reducing convenience of relatively low cost when compared to various 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 make use of 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 equipment, and includes a right angle output orientation. This type of reduction gear package is generally used to take a rated motor acceleration and create a low speed output with higher torque value based on the reduction ratio. They often times can solve space-saving problems since the worm equipment reducer is one of the sleekest reduction gearboxes available due to the small diameter of its output gear.
worm gear reducerWorm equipment reducers are also a popular type of rate reducer because they offer the greatest speed decrease in the tiniest package. With a high ratio of speed reduction and high torque result 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, 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 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 manufactured with tough compression-molded glass-fill up polyester housings for a durable, long lasting, light-weight speed reducer that is also compact, noncorrosive, and nonmetallic.
Features
Our worm equipment reducers offer a choice of a good or hollow output shaft and feature an adjustable mounting position. Both the SW-1 and the SW-5, however, can withstand shock loading much better than other decrease gearbox styles, making them perfect for demanding applications.

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

Description
The HDR Series worm gear reducers are found 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 models are 56C or 145TC flange install with either right, still left or dual result shafts or a hollow bore result. The indirect drive models are shaft input-shaft output boxes for use with sprocket or pulley drive systems. They provide an effective low cost solution to speed decrease and increased torque, with higher tolerances for shock loading than helical equipment reducers.
In order to select a gearbox speed reducer, you will have to determine the mandatory torque and assistance factor for the application form. Click on “Specifications” above for a table that will assist in determining the service element. For service factors above 1.0, multiply the mandatory torque by the provider factor.
