Single reduction worm gearing offers high ratio reduction with few moving parts in a close-coupled small drive. The proper angle set up of driving-to-driven machine requires a minimum of space. Input and output shafts can be prolonged in either or both directions in horizontal or vertical arrangements adaptable to any mounting requirement. Efficient engine speeds are decreased to slow speed requirements of many industrial machines in one reduction.

The exclusive usage of the involute Helicoid Thread form (with departing side contact) on the worm and gear provides for high efficiencies, and lengthy service life. The hardened surface and polished alloy steel worm develops a soft, work hardened surface on the bronze gear. For this reason worm gears put on in and improve with prolonged service while various other gears are wearing out. Ever-Power offers a broad collection of model configurations, sizes, ratios, and add-ons from our standard products.
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 maximum rigidity and strength that allows the tranny of higher horsepower levels than are feasible with regular cast iron systems. Extra heavy aspect plates connect the worm and gear shaft bearing facilitates, assuring appropriate meshing of the gear under all load circumstances. In smaller sizes, fabricated steel reducers are interchangeable with Ever-Power standard cast iron reducers.
Custom Designs
Ever-Power can offer custom speed and reversed engineered reducers for your application, be it a new 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 elevation 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 includes a hardened, floor and polished alloy steel worm. This mixture develops a smooth, work-hardened mating surface of the bronze equipment which increases 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 operation and permits the probability of large acceleration reductions. These gears are available from share in a wide variety of ratios, from only 4:1 up to 3600:1. The small design and structure allows worm equipment reducers to be placed in a relatively small space. Thus, high reductions in a restricted package size may be accomplished with this configuration. Our worm gear features the continuous sliding tooth action between worm and one’s teeth. This escalates the tolerance for weighty 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 equipment reducer is one kind of reduction gear container which includes a worm pinion insight, an output worm gear, and features a right angle result orientation. This type of reduction gear box is normally used to take a rated motor quickness and produce a low speed result with higher torque worth based on the decrease ratio. They often times can solve space-saving problems since the worm equipment reducer is one of the sleekest decrease gearboxes available due to the small diameter of its output gear.
worm gear reducerWorm gear reducers are also a favorite type of swiftness 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 gear reducer. Some of the most common applications for worm gears are available in tuning instruments, medical screening 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 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 tough compression-molded glass-fill polyester housings for a long lasting, long lasting, light weight speed reducer that’s also compact, noncorrosive, and nonmetallic.
Features
Our worm equipment 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, nevertheless, can withstand shock loading much better than other decrease gearbox designs, making them ideal for demanding applications.

Worm Equipment Reducers also called worm gearbox or worm quickness reducers. Worm gear reducers are utilized for speed decrease and raising the torque for electric powered engine drives. You can decide to mount your NEMA electric motor to the reducer utilizing the NEMA C encounter flange or use a coupling. If you need a coupling for the result or input shaft find our coupling section for selecting a coupling. You can expect four assemblies left hand and right hands and double result shaft and shaft input and shaft output. Interchangeable with the majority of worm gear manufactures.

Description
The HDR Series worm equipment reducers are used in low to moderate horsepower applications to lessen speeds and increase torque. Worm gear reducers are available in direct or indirect drive, direct drive versions are 56C or 145TC flange mount with either right, remaining or dual output shafts or a hollow bore output. The indirect drive models are shaft input-shaft output boxes for use with sprocket or pulley drive systems. They offer an effective low cost solution to speed decrease and improved torque, with higher tolerances for shock loading than helical equipment reducers.
In order to decide on a gearbox speed reducer, you will need to determine the required torque and program factor for the application form. Click on “Specifications” above for a table that will assist in identifying the service element. For service factors above 1.0, multiply the mandatory torque by the program factor.
