worm gear speed reducer

Single reduction worm gearing provides high ratio reduction with couple of shifting parts in a close-coupled compact drive. The right angle set up of driving-to-driven machine takes a minimum of space. Input and result shafts can be extended in either or both directions in horizontal or vertical plans adaptable to any installation requirement. Efficient motor speeds are reduced to sluggish speed requirements of several industrial machines in a single reduction.

The exclusive utilization of the involute Helicoid Thread form (with departing side contact) on the worm and gear provides for high efficiencies, and lengthy service existence. The hardened floor and polished alloy steel worm develops a easy, work hardened surface on the bronze gear. For this reason worm gears use in and improve with extented service while various other gears are deteriorating. Ever-Power offers a broad collection of model configurations, sizes, ratios, and accessories from our standard product line.
Fabricated Designs
If your application involves severe shock loads or feasible housing damage from external sources (as in steel mills or mobile devices applications) Ever-Power can offer fabricated steel housings with up to a 48″ center distances. Fabricated housings provide maximum rigidity and strength which allows the tranny of higher horsepower levels than are possible with standard cast iron devices. Extra heavy aspect plates connect the worm and gear shaft bearing facilitates, 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 provide custom quickness and reversed engineered reducers for the application, be it a new project or a primary drop-in replacement for a competitor’s speed reducer. Fabricated steel reducers allow Ever-Power to complement a competitor’s footprint, centerline, and shaft height allowing a primary drop-in alternative 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, surface and polished alloy metal worm. This mixture develops a smooth, work-hardened mating surface 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 simple and quiet operation and allows for the probability of large rate reductions. These gears can be found from stock in a wide variety of ratios, from as low as 4:1 up to 3600:1. The compact design and construction allows worm gear reducers to be placed in a comparatively small space. Thus, very high reductions in a restricted package size can be achieved with this configuration. Our worm gear features the constant sliding tooth action between worm and the teeth. This escalates the tolerance for weighty loads and shock loads. Worm gear drives offer users high reducing convenience of relatively low cost in comparison with 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 gear reducer is one kind of reduction gear container which contains a worm pinion insight, an output worm gear, and features a right angle result orientation. This kind of reduction gear package is normally used to take a rated motor velocity and produce a low speed result with higher torque worth based on the decrease ratio. They often times can resolve space-saving problems because the worm gear reducer is among the sleekest decrease gearboxes available due to the small diameter of its result gear.
worm gear reducerWorm equipment reducers are also a favorite type of rate reducer because they provide the greatest speed reduction in the smallest package. With a high ratio of speed decrease and high torque output 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 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 of these options are produced with rugged compression-molded glass-fill up polyester housings for a durable, long lasting, light-weight speed reducer that’s also compact, noncorrosive, and nonmetallic.
Features
Our worm equipment reducers offer an option of a good or hollow result shaft and feature an adjustable mounting placement. Both the SW-1 and the SW-5, however, can withstand shock loading better than other decrease gearbox styles, making them ideal for demanding applications.

Worm Equipment Reducers also called worm gearbox or worm quickness reducers. Worm gear reducers are utilized for speed reduction and increasing the torque for electrical engine drives. You can decide to install your NEMA electric 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 see our coupling section for choosing the coupling. We offer four assemblies left hands and right hands and double result shaft and shaft insight and shaft output. Interchangeable with many 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 can be found in direct or indirect drive, direct drive models are 56C or 145TC flange mount with either right, left or dual output shafts or a hollow bore output. The indirect drive models are shaft input-shaft result boxes for make use of with sprocket or pulley drive systems. They offer an effective low priced solution to speed decrease and improved torque, with higher tolerances for shock loading than helical gear reducers.
In order to select a gearbox speed reducer, you will need to determine the required torque and assistance factor for the application form. Click on “Specifications” above for a table that will assist in determining the service element. For service factors above 1.0, multiply the required torque by the services factor.
