worm gear speed reducer

Solitary reduction worm gearing provides high ratio reduction with couple of shifting parts in a close-coupled compact drive. The right angle arrangement of driving-to-driven machine requires a minimum of space. Input and output shafts can be extended in either or both directions in horizontal or vertical arrangements adaptable to any installation requirement. Efficient motor speeds are reduced to sluggish speed requirements of many industrial machines in one reduction.

The exclusive use of the involute Helicoid Thread form (with worm gear speed reducer departing side contact) on the worm and gear offers high efficiencies, and long service life. The hardened floor and polished alloy steel worm develops a easy, work hardened surface area on the bronze equipment. For this reason worm gears put on in and improve with prolonged service while other gears are deteriorating. Ever-Power offers a broad selection of model configurations, sizes, ratios, and add-ons from our standard products.
Fabricated Designs
If the application involves severe shock loads or possible housing damage from external sources (as in steel mills or mobile tools applications) Ever-Power can provide fabricated steel housings with up to a 48″ center distances. Fabricated housings provide maximum rigidity and strength that allows the tranny of higher horsepower amounts than are feasible with regular cast iron systems. Extra heavy aspect plates connect the worm and gear shaft bearing supports, 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 speed and reversed engineered reducers for the application, be it a fresh project or a direct drop-in replacement for a competitor’s speed reducer. Fabricated metal reducers enable Ever-Power to complement 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 manufactured from phosphorous bronze. Our design also includes a hardened, ground and polished alloy metal worm. This mixture develops a simple, work-hardened mating surface area of the bronze equipment which boosts with prolonged service.
Worm gearing is a class of equipment reducers that utilizes correct angle, nonintersecting shafts. This form of reducer provides even and quiet procedure and permits the likelihood of large speed reductions. These gears can be found from share in a wide variety of ratios, from as low as 4:1 up to 3600:1. The compact design and building allows worm equipment reducers to be placed in a comparatively 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 actions between worm and one’s teeth. This escalates the tolerance for heavy loads and shock loads. Worm gear drives provide users high reducing capacity for relatively low cost when compared to some 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 use worm gearing are: conveyors, mixers and bucket elevators.

A worm gear reducer is one kind of reduction gear package which contains a worm pinion insight, an output worm equipment, and includes a right angle output orientation. This kind of reduction gear package is generally used to have a rated motor quickness and produce a low speed result with higher torque worth based on the reduction ratio. They often can resolve space-saving problems because the worm equipment reducer is one of the sleekest reduction gearboxes available due to the small diameter of its result gear.
worm gear reducerWorm equipment reducers are also a favorite type of swiftness reducer because they provide the greatest speed reduction in the tiniest package. With a higher ratio of speed decrease and high torque output multiplier, it’s unsurprising that many power transmission systems utilize a worm gear 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 gear 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 of these options are produced with tough compression-molded glass-fill polyester housings for a durable, long lasting, light weight speed reducer that is also compact, noncorrosive, and nonmetallic.
Features
Our worm equipment reducers offer an option of a solid or hollow output shaft and feature 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 well suited for demanding applications.

Worm Gear Reducers also known as worm gearbox or worm acceleration reducers. Worm equipment reducers are utilized for speed reduction and increasing the torque for electric engine drives. You can choose to mount your NEMA engine to the reducer by using the NEMA C face flange or use a coupling. If you want a coupling for the result or input shaft observe our coupling section for choosing the coupling. You can expect four assemblies left hand and right hands and double output shaft and shaft insight and shaft output. Interchangeable with the majority of worm gear manufactures. See data sheet in product overview for diamensions. If you don’t see your type, make sure you Contact Us.

Description
The HDR Series worm equipment reducers are found in low to moderate horsepower applications to reduce speeds and increase torque. Worm gear reducers are available in direct or indirect drive, direct drive versions are 56C or 145TC flange attach with either right, 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 priced solution to speed decrease and increased torque, with higher tolerances for shock loading than helical equipment reducers.
In order to decide on a gearbox speed reducer, you will have to determine the required torque and services factor for the application form. Click on “Specs” above for a table that will assist in identifying the service element. For service elements above 1.0, multiply the mandatory torque by the provider factor.
