Solitary reduction worm gearing offers high ratio reduction with few moving parts in a close-coupled small drive. The proper angle arrangement of driving-to-driven machine takes a the least space. Input and result shafts can be extended in either or both directions in horizontal or vertical plans adaptable to any mounting requirement. Efficient motor 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 offers high efficiencies, and long service existence. The hardened ground and polished alloy metal worm develops a smooth, work hardened surface on the bronze equipment. Because of this worm gears put on in and improve with prolonged service while other gears are wearing out. Ever-Power offers a wide selection of model configurations, sizes, ratios, and components 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 devices applications) Ever-Power can provide 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 standard cast iron models. Extra heavy aspect plates connect the worm and gear shaft bearing supports, assuring proper meshing of the gear 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 velocity and reversed engineered reducers for the application, be it a fresh project or a direct drop-in alternative to a competitor’s speed reducer. Fabricated metal reducers enable Ever-Power to match a competitor’s footprint, centerline, and shaft height allowing a direct drop-in replacement saving the customer time and money.
Long – Quiet Life
All worm gears in Ever-Power reducers are manufactured from phosphorous bronze. Our style also incorporates a hardened, floor and polished alloy metal worm. This mixture develops a even, work-hardened mating surface area of the bronze gear which boosts with prolonged service.
Worm gearing is a course of equipment reducers that utilizes right angle, nonintersecting shafts. This form of reducer provides soft and quiet procedure and allows for the probability of large quickness reductions. These gears can be found from share in a wide variety of ratios, from as low as 4:1 to as much as 3600:1. The compact design and building allows worm gear reducers to be placed in a relatively small space. Thus, high reductions in a limited package size can be achieved with this configuration. Our worm gear features the continuous sliding tooth action between worm and the teeth. This escalates the tolerance for heavy loads and shock loads. Worm gear drives provide users high reducing convenience of relatively low cost when compared to some 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 utilize worm gearing are: conveyors, mixers and bucket elevators.

A worm gear reducer is one type of reduction gear container which contains a worm pinion insight, an output worm equipment, and features a right angle result orientation. This kind of reduction gear container is normally used to take a rated motor velocity and create 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 among the sleekest decrease gearboxes available because of the little diameter of its output gear.
worm gear reducerWorm gear reducers are also a favorite type of speed reducer because they offer the greatest speed reduction in the tiniest package. With a higher ratio of speed decrease and high torque result multiplier, it’s unsurprising that many power transmission systems make use of a worm gear reducer. Some of the most typical applications for worm gears are available in tuning instruments, medical assessment equipment, elevators, security 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 rugged compression-molded glass-fill polyester housings for a long lasting, long lasting, light-weight speed reducer that is also compact, noncorrosive, and nonmetallic.
Features
Our worm gear reducers offer a choice of a solid or hollow result shaft and feature an adjustable mounting placement. Both SW-1 and the SW-5, nevertheless, can endure shock loading much better than other reduction gearbox styles, making them ideal for demanding applications.

Worm Gear Reducers also called worm gearbox or worm quickness reducers. Worm gear reducers are used for speed reduction and raising the torque for electrical motor drives. You can choose to install your NEMA electric motor to the reducer by using the NEMA C face flange or use a coupling. If you want a coupling for the result or input shaft find our coupling section for choosing the coupling. You can expect four assemblies left hands and right hands and double result shaft and shaft input and shaft result. Interchangeable with the majority of worm gear manufactures.

Description
The HDR Series worm gear reducers are found 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, left or dual output shafts or a hollow bore result. The indirect drive versions are shaft input-shaft result boxes for use with sprocket or pulley drive systems. They provide an effective low cost solution to speed reduction and increased torque, with higher tolerances for shock loading than helical equipment 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 “Specs” above for a table that will assist in identifying the service element. For service factors above 1.0, multiply the mandatory torque by the support factor.
