worm gear speed reducer
One reduction worm gearing offers high ratio reduction with few moving parts in a close-coupled compact drive. The proper angle arrangement of driving-to-driven machine takes a the least space. Input and output shafts can be prolonged in either or both directions in horizontal or vertical plans adaptable to any mounting requirement. Efficient electric motor speeds are reduced 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 offers high efficiencies, and lengthy service existence. The hardened ground and polished alloy steel worm develops a clean, work hardened surface on the bronze equipment. Because of this worm gears wear in and improve with prolonged service while various other gears are wearing out. Ever-Power offers a wide selection of model configurations, sizes, ratios, and add-ons from our standard product line.
Fabricated Designs
If your application involves serious shock loads or possible 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 that allows the transmission of higher horsepower levels than are feasible with regular cast iron models. Extra heavy part plates connect the worm and equipment shaft bearing facilitates, assuring appropriate meshing of the apparatus under all load circumstances. In smaller sizes, fabricated metal reducers are interchangeable with Ever-Power standard cast iron reducers.
Custom Designs
Ever-Power can offer custom velocity and reversed engineered reducers for the application, be it a new project or a direct drop-in replacement for a competitor’s swiftness reducer. Fabricated steel reducers enable Ever-Power to complement a competitor’s footprint, centerline, and shaft elevation allowing a primary drop-in substitute saving the client time and money.
Long – Quiet Life
All worm gears in Ever-Power reducers are manufactured from phosphorous bronze. Our style also includes a hardened, surface and polished alloy metal worm. This combination develops a easy, work-hardened mating surface area of the bronze equipment which boosts with prolonged service.
Worm gearing is a course of gear reducers that utilizes right angle, nonintersecting shafts. This form of reducer provides soft and quiet operation and permits the probability of large acceleration reductions. These gears are available from stock in a wide selection of ratios, from only 4:1 to as much as 3600:1. The compact design and structure allows worm gear reducers to be positioned in a relatively small space. Thus, high reductions in a limited package size can be achieved with this configuration. Our worm equipment 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 in comparison with various other types of gearing.
The use 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 equipment reducer is one type of reduction gear box which consists of a worm pinion insight, an output worm gear, and includes a right angle output orientation. This kind of reduction gear container is generally used to take a rated motor velocity and create a low speed result with higher torque worth based on the decrease ratio. They often times can resolve space-saving problems because the worm equipment reducer is one of the sleekest decrease gearboxes available due to the little diameter of its result gear.
worm gear reducerWorm equipment reducers are also a favorite type of velocity reducer because they provide the greatest speed reduction in the smallest package. With a higher ratio of speed decrease and high torque output multiplier, it’s unsurprising that lots of power transmission systems utilize a worm gear 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 offers 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 manufactured with tough 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 equipment reducers offer an option of a solid or hollow output shaft and show an adjustable mounting position. Both the SW-1 and the SW-5, however, can endure shock loading much better than other decrease gearbox designs, making them perfect for demanding applications.

Worm Equipment Reducers also known as worm gearbox or worm acceleration reducers. Worm equipment reducers are used for speed decrease and raising the torque for electrical electric motor drives. You can choose to mount your NEMA motor to the reducer by using the NEMA C encounter flange or make use of a coupling. If you want a coupling for the output or input shaft discover our coupling section for choosing the coupling. We offer four assemblies left hand and right hand and double output shaft and shaft input and shaft result. Interchangeable with the majority of worm gear manufactures.

Description
The HDR Series worm equipment 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 attach with either right, remaining or dual output 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 offer an effective low cost solution to speed reduction and increased 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 service factor for the application form. Click on “Specifications” above for a table that will assist in identifying the service factor. For service factors above 1.0, multiply the mandatory torque by the assistance factor.
