worm gear speed reducer

Single reduction worm gearing offers high ratio reduction with couple of shifting parts in a close-coupled compact drive. The right angle arrangement 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 mounting requirement. Efficient engine speeds are reduced to slow speed requirements of several industrial machines in one reduction.

The exclusive utilization 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 surface and polished alloy metal worm develops a even, work hardened surface on the bronze equipment. Because of this worm gears use in and improve with extented service while additional 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 the 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 48″ center distances. Fabricated housings provide optimum rigidity and strength that allows the transmission of higher horsepower levels than are feasible with standard cast iron models. Extra heavy side plates connect the worm and equipment shaft bearing facilitates, assuring correct meshing of the apparatus under all load conditions. In smaller sizes, fabricated steel reducers are interchangeable with Ever-Power regular cast iron reducers.
Custom Designs
Ever-Power can offer custom acceleration and reversed engineered reducers for your application, be it a fresh project or a primary drop-in alternative to a competitor’s quickness reducer. Fabricated metal reducers enable Ever-Power to match a competitor’s footprint, centerline, and shaft height allowing a primary 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 includes a hardened, ground and polished alloy metal worm. This combination develops a soft, work-hardened mating surface area of the bronze equipment which increases with prolonged service.
Worm gearing is a course of gear reducers that utilizes correct angle, nonintersecting shafts. This form of reducer provides smooth and quiet operation and allows for the probability of large quickness reductions. These gears are available from stock in a wide variety of ratios, from only 4:1 up to 3600:1. The compact design and construction allows worm equipment reducers to be positioned in a relatively 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 large loads and shock loads. Worm gear drives provide users high reducing capacity for relatively low cost in comparison with various other types of gearing.
The usage of worm gearing extends across many industries including food, beverage and grain and has many applications. Some applications that make use of worm gearing are: conveyors, mixers and bucket elevators.

A worm gear reducer is one type of reduction gear package which contains a worm pinion input, an output worm equipment, and includes a right angle result orientation. This type of reduction gear container is generally used to take a rated motor velocity and produce a low speed output with higher torque worth based on the decrease ratio. They often times can solve space-saving problems because the worm equipment reducer is among 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 provide the greatest speed reduction 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 utilize a worm equipment reducer. Some of the most common applications for worm gears are available in tuning instruments, medical assessment equipment, elevators, protection gates, and conveyor belts.
SW-1 and SW-5
Torque Transmission offers 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 these options are produced with rugged compression-molded glass-fill polyester housings for a long lasting, long lasting, light weight speed reducer that is also compact, non-corrosive, and nonmetallic.
Features
Our worm gear reducers offer an option of a solid or hollow output shaft and show an adjustable mounting placement. Both the SW-1 and the SW-5, nevertheless, can endure 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 quickness reducers. Worm gear reducers are used for speed decrease and increasing the torque for electrical electric motor drives. You can decide to install your NEMA electric motor to the reducer by using the NEMA C encounter flange or make use of a coupling. If you want a coupling for the output or input shaft find our coupling section for choosing the coupling. You can expect four assemblies left hand and right hands and double result shaft and shaft insight and shaft result. Interchangeable with most 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 versions are 56C or 145TC flange install with either right, still left or dual output shafts or a hollow bore result. The indirect drive versions are shaft input-shaft result boxes for make use of with sprocket or pulley drive systems. They provide an effective low cost 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 required torque and provider factor for the application form. Click on “Specifications” above for a desk that will aid in identifying the service factor. For service factors above 1.0, multiply the mandatory torque by the service factor.
