worm gear speed reducer
One reduction worm gearing offers high ratio reduction with couple of moving 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 arrangements adaptable to any installation requirement. Efficient motor speeds are reduced to slow speed requirements of many industrial machines in a single 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 lifestyle. The hardened ground and polished alloy metal worm develops a even, work hardened surface on the bronze equipment. For this reason worm gears use in and improve with extented service while various other gears are deteriorating. Ever-Power offers a broad collection of model configurations, sizes, ratios, and add-ons from our standard products.
Fabricated Designs
If your application involves serious shock loads or possible housing damage from external sources (as in steel mills or mobile devices applications) Ever-Power can offer fabricated steel housings with up to 48″ center distances. Fabricated housings provide optimum rigidity and strength which allows the transmitting of higher horsepower levels than are possible with regular cast iron products. Extra heavy side plates connect the worm and equipment shaft bearing facilitates, assuring proper meshing of the gear under all load circumstances. In smaller sized sizes, fabricated metal reducers are interchangeable with Ever-Power standard cast iron reducers.
Custom Designs
Ever-Power can offer custom rate and reversed engineered reducers for the application, be it a fresh project or a primary drop-in alternative to a competitor’s acceleration reducer. Fabricated metal reducers allow Ever-Power to complement a competitor’s footprint, centerline, and shaft elevation allowing a primary drop-in replacement saving the customer time and money.
Long – Quiet Life
All worm gears in Ever-Power reducers are manufactured from phosphorous bronze. Our style also incorporates a hardened, floor and polished alloy steel worm. This mixture develops a simple, work-hardened mating surface area of the bronze gear which enhances with prolonged service.
Worm gearing is a course of equipment reducers that utilizes correct angle, nonintersecting shafts. This style of reducer provides soft and quiet procedure and allows for the likelihood of large acceleration reductions. These gears are available from share in a wide variety of ratios, from as low as 4:1 to as much as 3600:1. The compact design and structure allows worm equipment reducers to be positioned in a comparatively small space. Thus, high reductions in a restricted package size can be achieved with this configuration. Our worm gear features the continuous sliding tooth action between worm and one’s teeth. This escalates the tolerance for large loads and shock loads. Worm gear drives offer users high reducing capacity for 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 utilize worm gearing are: conveyors, mixers and bucket elevators.

A worm gear reducer is one kind of reduction gear package which includes a worm pinion insight, an output worm gear, and features a right angle result 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 worth based on the decrease ratio. They often times can resolve space-saving problems because the worm gear reducer is one of the sleekest reduction gearboxes available because of the little diameter of its output gear.
worm gear reducerWorm gear reducers are also a favorite type of speed reducer because they offer the greatest speed reduction in the smallest package. With a higher ratio of speed reduction and high torque result multiplier, it’s unsurprising that many power transmission systems utilize a worm equipment reducer. Some of the most common applications for worm gears can be found in tuning instruments, medical assessment equipment, elevators, security 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 can be found in a range 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 rugged compression-molded glass-fill up polyester housings for a long lasting, long lasting, light-weight speed reducer that is also compact, noncorrosive, and nonmetallic.
Features
Our worm gear reducers offer a choice of a solid or hollow result shaft and feature an adjustable mounting placement. Both the SW-1 and the SW-5, nevertheless, can withstand shock loading much better than other decrease gearbox styles, making them well suited for demanding applications.

Worm Gear Reducers also called worm gearbox or worm swiftness reducers. Worm equipment reducers are utilized for speed reduction and increasing the torque for electric powered electric motor drives. You can decide to install your NEMA motor to the reducer by using the NEMA C face flange or make use of a coupling. If you want a coupling for the result or input shaft discover our coupling section for choosing the coupling. We offer four assemblies left hand and right hands and double result shaft and shaft input and shaft output. Interchangeable with many 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 install with either right, still left or dual output shafts or a hollow bore result. The indirect drive models are shaft input-shaft result boxes for make use of with sprocket or pulley drive systems. They offer an effective low priced solution to speed decrease and improved torque, with higher tolerances for shock loading than helical gear reducers.
In order to decide on a gearbox speed reducer, you will need to determine the mandatory torque and services factor for the application form. Click on “Specifications” above for a desk that will aid in determining the service aspect. For service factors above 1.0, multiply the required torque by the provider factor.
