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 set up of driving-to-driven machine takes a minimum of space. Input and output shafts can be extended in either or both directions in horizontal or vertical arrangements adaptable to any mounting requirement. Efficient motor speeds are reduced to sluggish speed requirements of several industrial machines in one reduction.

The exclusive use of the involute Helicoid Thread form (with leaving side contact) on the worm and gear offers high efficiencies, and long service existence. The hardened ground and polished alloy metal worm develops a even, work hardened surface on the bronze equipment. For this reason worm gears wear in and improve with prolonged service while other gears are deteriorating. Ever-Power offers a wide selection of model configurations, sizes, ratios, and add-ons from our standard product line.
Fabricated Designs
If the application involves severe shock loads or possible housing damage from external sources (as in steel mills or mobile products applications) Ever-Power can provide fabricated steel housings with up to 48″ center distances. Fabricated housings provide maximum rigidity and strength which allows the tranny of higher horsepower amounts than are possible with standard cast iron products. Extra heavy aspect plates connect the worm and equipment shaft bearing supports, assuring proper meshing of the gear under all load conditions. In smaller sizes, fabricated steel reducers are interchangeable with Ever-Power standard cast iron reducers.
Custom Designs
Ever-Power can provide custom acceleration and reversed engineered reducers for your application, be it a new project or a direct drop-in replacement for a competitor’s velocity reducer. Fabricated steel reducers enable Ever-Power to match a competitor’s footprint, centerline, and shaft elevation allowing a primary drop-in alternative saving the customer time and money.
Long – Quiet Life
All worm gears in Ever-Power reducers are produced from phosphorous bronze. Our design also incorporates a hardened, floor and polished alloy metal worm. This combination develops a easy, work-hardened mating surface of the bronze gear which boosts with prolonged service.
Worm gearing is a course of equipment reducers that utilizes correct angle, nonintersecting shafts. This form of reducer provides clean and quiet procedure and allows for the probability of large velocity reductions. These gears are available from stock in a wide variety of ratios, from as low as 4:1 up to 3600:1. The small design and structure allows worm equipment reducers to be positioned in a relatively small space. Thus, very high reductions in a limited package size may be accomplished with this configuration. Our worm equipment features the constant sliding tooth action between worm and the teeth. This escalates the tolerance for large loads and shock loads. Worm gear drives provide users high reducing convenience of relatively low cost when compared to some 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 use worm gearing are: conveyors, mixers and bucket elevators.

A worm equipment reducer is one type of reduction gear container which contains a worm pinion insight, an output worm equipment, and features a right angle output orientation. This kind of reduction gear box is generally used to have a rated motor velocity and create a low speed output with higher torque value based on the decrease 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 output gear.
worm gear reducerWorm gear reducers are also a popular type of rate reducer because they provide the greatest speed reduction in the smallest package. With a high ratio of speed reduction and high torque output multiplier, it’s unsurprising that lots of power transmission systems make use of a worm equipment reducer. Some of the most common applications for worm gears can be found in tuning instruments, medical screening equipment, elevators, security 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 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 durable 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 show an adjustable mounting position. Both the SW-1 and the SW-5, nevertheless, can endure shock loading better than other decrease gearbox styles, making them ideal for demanding applications.

Worm Equipment Reducers also referred to as worm gearbox or worm rate reducers. Worm equipment reducers are used for speed reduction and raising the torque for electrical electric motor drives. You can decide to attach your NEMA motor to the reducer utilizing the NEMA C encounter flange or make use of a coupling. If you need a coupling for the output or input shaft observe our coupling section for choosing the coupling. We offer four assemblies left hand and right hand and double output shaft and shaft insight and shaft result. Interchangeable with the majority of worm gear manufactures.

Description
The HDR Series worm gear reducers are found in low to moderate horsepower applications to reduce 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, still left or dual output 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 priced solution to speed reduction 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 required torque and support factor for the application. Click on “Specs” above for a desk that will assist in determining the service element. For service elements above 1.0, multiply the required torque by the services factor.
