worm gear speed reducer

Single reduction worm gearing provides high ratio reduction with couple of moving parts in a close-coupled compact drive. The proper angle arrangement of driving-to-driven machine takes a minimum of space. Input and output shafts can be prolonged in either or both directions in horizontal or vertical plans 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 lengthy service lifestyle. The hardened surface and polished alloy metal worm develops a simple, work hardened surface area on the bronze gear. Because of this worm gears wear in and improve with prolonged service while additional gears are deteriorating. Ever-Power offers a broad collection of model configurations, sizes, ratios, and add-ons from our standard product line.
Fabricated Designs
If your application involves severe shock loads or feasible housing damage from external sources (as in steel mills or mobile tools applications) Ever-Power can offer fabricated steel housings with up to a 48″ center distances. Fabricated housings provide optimum rigidity and strength that allows the transmitting of higher horsepower levels than are feasible with regular cast iron devices. Extra heavy side plates connect the worm and equipment shaft bearing supports, assuring proper meshing of the apparatus under all load conditions. In smaller sized sizes, fabricated steel reducers are interchangeable with Ever-Power regular cast iron reducers.
Custom Designs
Ever-Power can provide custom acceleration 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 metal reducers allow Ever-Power to match a competitor’s footprint, centerline, and shaft height allowing a direct 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 incorporates a hardened, surface and polished alloy metal worm. This combination develops a easy, work-hardened mating surface area of the bronze gear which enhances with prolonged service.
Worm gearing is a class of gear reducers that utilizes correct angle, nonintersecting shafts. This style of reducer provides smooth and quiet operation and allows for the probability of large swiftness reductions. These gears can be found from stock in a wide selection of ratios, from only 4:1 up to 3600:1. The compact design and construction allows worm equipment reducers to be placed in a comparatively small space. Thus, high reductions in a limited package size may be accomplished with this configuration. Our worm equipment features the continuous sliding tooth actions between worm and one’s teeth. This increases the tolerance for heavy loads and shock loads. Worm gear drives provide users high reducing capacity for 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.

-Worm Wheel: Manufactured with Carbon alloy ALBC2, teeth are machined by precision CNC hobbing machine to sustain high impact.
A worm gear reducer is one kind of reduction gear box which contains a worm pinion input, an output worm equipment, and features a right angle output orientation. This kind of reduction gear container is normally used to take a rated motor speed and produce a low speed output with higher torque value based on the decrease ratio. They often can solve space-saving problems because the worm equipment reducer is among the sleekest reduction gearboxes available due to the small diameter of its result gear.
worm gear reducerWorm gear reducers are also a popular type of acceleration 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 many power transmission systems make use of a worm gear reducer. Some of the most common applications for worm gears are available in tuning instruments, medical examining 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 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 of these options are produced with rugged 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 solid or hollow result shaft and show an adjustable mounting placement. Both SW-1 and the SW-5, however, can withstand shock loading much better than other decrease gearbox styles, making them ideal for demanding applications.

Worm Equipment Reducers also called worm gearbox or worm acceleration reducers. Worm equipment reducers are used for speed decrease and raising the torque for electrical engine drives. You can choose to attach your NEMA motor to the reducer by using the NEMA C face flange or make use of a coupling. If you need a coupling for the output or input shaft observe our coupling section for selecting a coupling. We offer four assemblies left hand and right hands 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 lessen speeds and increase torque. Worm gear reducers can be found in direct or indirect drive, direct drive versions are 56C or 145TC flange install with either right, still left or dual result shafts or a hollow bore output. The indirect drive versions are shaft input-shaft output boxes for use with sprocket or pulley drive systems. They provide an effective low priced 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 required torque and provider factor for the application form. Click on “Specifications” above for a table that will aid in identifying the service aspect. For service factors above 1.0, multiply the mandatory torque by the program factor.
