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 the least space. Input and output shafts can be prolonged in either or both directions in horizontal or vertical arrangements adaptable to any mounting requirement. Efficient motor speeds are decreased to slower speed requirements of several 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 long service lifestyle. The hardened ground and polished alloy metal worm develops a clean, work hardened surface on the bronze equipment. For this reason worm gears wear in and improve with prolonged service while 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 the application involves serious shock loads or possible housing damage from external sources (as in steel mills or mobile equipment 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 transmission of higher horsepower amounts than are feasible with standard cast iron systems. Extra heavy aspect plates connect the worm and gear shaft bearing supports, assuring correct meshing of the gear under all load circumstances. In smaller sized sizes, fabricated steel reducers are interchangeable with Ever-Power regular cast iron reducers.
Custom Designs
Ever-Power can offer custom speed and reversed engineered reducers for the 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 complement a competitor’s footprint, centerline, and shaft height allowing a direct drop-in substitute saving the customer time and money.
Long – Quiet Life
All worm gears in Ever-Power reducers are produced from phosphorous bronze. Our design also incorporates a hardened, floor and polished alloy metal worm. This combination develops a soft, work-hardened mating surface of the bronze equipment which increases with prolonged service.
Worm gearing is a course of gear reducers that utilizes right angle, nonintersecting shafts. This style of reducer provides soft and quiet procedure and permits the probability of large speed reductions. These gears are available from stock in a wide variety of ratios, from as low as 4:1 up to 3600:1. The small design and construction allows worm equipment reducers to be positioned in a comparatively small space. Thus, very high reductions in a limited package size can be achieved with this configuration. Our worm gear 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 offer users high reducing convenience of 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 consists of a worm pinion input, an output worm equipment, and includes a right angle worm gear speed reducer Result orientation. This type of reduction gear box is normally used to have a rated motor rate and create a low speed result with higher torque value based on the decrease ratio. They often can solve space-saving problems because the worm gear reducer is one of 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 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 lots of power transmission systems utilize a worm gear reducer. Some of the most typical 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 gear 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 of 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 output shaft and feature an adjustable mounting placement. Both SW-1 and the SW-5, however, can endure shock loading much better than other reduction gearbox styles, making them ideal for demanding applications.

Worm Equipment Reducers also referred to as worm gearbox or worm speed reducers. Worm equipment reducers are used for speed decrease and increasing the torque for electric powered electric motor drives. You can choose to attach your NEMA motor to the reducer utilizing the NEMA C encounter flange or make use of a coupling. If you want a coupling for the result 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 many worm gear manufactures.

Description
The HDR Series worm equipment 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 models are 56C or 145TC flange attach with either right, remaining or dual output 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 improved torque, with higher tolerances for shock loading than helical gear reducers.
In order to decide on a gearbox speed reducer, you will have to determine the mandatory torque and service factor for the application. Click on “Specifications” above for a table that will aid in identifying the service factor. For service elements above 1.0, multiply the mandatory torque by the support factor.
