worm gear speed reducer

Single reduction worm gearing offers 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 the least space. Input and result shafts can be prolonged in either or both directions in horizontal or vertical arrangements adaptable to any mounting requirement. Efficient engine speeds are reduced to sluggish speed requirements of many industrial machines in a single reduction.

The exclusive utilization of the involute Helicoid Thread form (with leaving side contact) on the worm and gear provides for high efficiencies, and long service lifestyle. The hardened floor and polished alloy metal worm develops a even, work hardened surface area 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 collection of model configurations, sizes, ratios, and accessories from our standard product line.
Fabricated Designs
If the application involves severe shock loads or feasible 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 that allows the tranny of higher horsepower amounts than are feasible with standard cast iron products. Extra heavy side plates connect the worm and gear shaft bearing facilitates, assuring proper 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 acceleration and reversed engineered reducers for your application, be it a new project or a primary drop-in replacement for a competitor’s velocity reducer. Fabricated steel reducers allow Ever-Power to complement a competitor’s footprint, centerline, and shaft elevation allowing a primary drop-in substitute saving the customer time and money.
Long – Quiet Life
All worm gears in Ever-Power reducers are manufactured from phosphorous bronze. Our style also includes a hardened, floor and polished alloy metal worm. This mixture develops a even, work-hardened mating surface area of the bronze gear which increases with prolonged service.
Worm gearing is a class of equipment reducers that utilizes right angle, nonintersecting shafts. This style of reducer provides simple and quiet procedure and allows for the likelihood of large quickness reductions. These gears are available from stock in a wide selection of ratios, from as low as 4:1 up to 3600:1. The small design and construction allows worm gear reducers to be placed in a comparatively small space. Thus, very high reductions in a restricted worm gear speed reducer package size can be achieved with this configuration. Our worm equipment features the continuous sliding tooth actions between worm and the 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 utilize worm gearing are: conveyors, mixers and bucket elevators.

A worm equipment reducer is one type of reduction gear package which contains a worm pinion insight, an output worm gear, and features a right angle output orientation. This kind of reduction gear package is normally used to have a rated motor rate and produce a low speed result with higher torque value based on the reduction ratio. They often times can solve space-saving problems because the worm gear reducer is one of the sleekest decrease gearboxes available because of the small diameter of its result gear.
worm gear reducerWorm equipment reducers are also a popular type of swiftness reducer because they offer the greatest speed decrease 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 gear reducer. Some of the most typical applications for worm gears can be found in tuning instruments, medical tests equipment, elevators, protection 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 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 produced with tough compression-molded glass-fill polyester housings for a long lasting, long lasting, light weight speed reducer that’s also compact, non-corrosive, and nonmetallic.
Features
Our worm gear reducers offer a choice of a solid or hollow result shaft and feature an adjustable mounting position. Both the SW-1 and the SW-5, however, can withstand shock loading better than other decrease gearbox designs, making them well suited for demanding applications.

Worm Gear Reducers also known as worm gearbox or worm rate reducers. Worm gear reducers are utilized for speed reduction and raising the torque for electrical engine drives. You can choose to attach your NEMA engine to the reducer by using the NEMA C encounter flange or make use of a coupling. If you need a coupling for the output or input shaft see our coupling section for choosing the coupling. We offer four assemblies left hands and right hand and double output shaft and shaft input and shaft output. Interchangeable with most worm gear manufactures. See data sheet in item overview for diamensions. If you don’t see your type, please Contact Us.

Description
The HDR Series worm gear reducers are used 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 versions are 56C or 145TC flange attach with either right, still left or dual result 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 improved torque, with higher tolerances for shock loading than helical gear reducers.
In order to select a gearbox speed reducer, you will have to determine the required torque and assistance factor for the application. Click on “Specs” above for a desk that will assist in identifying the service element. For service elements above 1.0, multiply the mandatory torque by the support factor.
