Atlas Gear Co.

Crowned Gears are necessary for applications where noise is a concern. Crowning gear teeth reduces noise by alleviating misalignment through either assembly or thrust problems. We are able to achieve crowning by any one of three means. One is by crown hobbing in one of our CNC gear hobbing machines, without any additional process. We can Also straight hob the gear teeth, then crown shave the teeth, achieving the necessary crown but also an even higher AGMA class level gear, and lastly we can straight hob and crown gear grind the gear to an even higher class level yet, up to AGMA Class 1314.

Straight Bevel Gears, and Mitre Gears can be manufactured from 24DP to 3DP up to 20 inches in diameter and produced to meet AGMA Class 8 levels. These gears can be run in sets and matched together using our Gleason motorized test machines assuring that the tooth contact bearing is correct with, and without loading, backlash between mates is correct to the mounting distance, and that the noise level of the gear doesn't exceed manufacturing requirements. If only one member of the set is being made, it can be tested to a master gear, or a "functional" mating part to insure that it will mate properly in assembly. We produce MitreBevel gears in many types of materials, from plastics to pre hardened alloy's up to 32-35 Rc.

At Atlas gear Company, we manufacture external spur and helical gears from 12" in diameter up to 36" diameter with face lengths up to 40" in length. Depending on the outside diameter and the diametral pitch. Using the latest in CNC gear cutting machinery our Pfauter and Mitsubishi gear hobber's are capable of cutting up to an AGMA class 1011 gear. Without any additional finishing process required. Gears up to 24" diameter can be hobbed and gear ground to an AGMA class 1314, for all those high speed, high accuracy gear requirements. We also have internal and external shaper cutting capabilities up to 36" in diameter with up to a 9" gear face, using our late model Mitsubishi SC 63 CNC gear shaper, also holding up to an AGMA Class 1011. This is one of the largest CNC gear shapers in the Midwest. Do you need gears with high numbers of teeth, or those problem prime numbers of teeth? Well with CNC gear cutting we can make those problems go away with ease. Computer programming for tooth indexing is the fastest , easiest way to handle those as well as many other problematic parts. Let Atlas Gear Company review your next gear program, and show you how we can save you time and money with state of the art processing.

At Atlas Gear China, LLC we produce complete gearboxes of various sizes, for almost any application. Applications include, but are not limited to, the following: Commercial Industrial Wind Energy Agricultural Mining Trucks Motorocycle Automotive In addition to our gearbox capabilities, we produce complete differential gear cases, as well as speed reducers and speed increasers of almost any size.

Always being one step ahead has helped Atlas Gear Company serve our customers just that much better than the next guy. Internal and shoulder type helical gear cutting is one way we do that. Using our new Mitsubishi ST-40 CNC gear shaper, rather than fixed guides, saves our customers months of time, and thousands of dollars to produce prototype, and short run production parts.

Involute and straight sided splines as well as serrations can be produced by hobbing, shaping, broaching, and rolling. Both internal and external splines can be cut using our CNC gear cutting machines, including internal or external helical splines. Hobbed splines can be made in lengths up to 50-60", depending on the diameter. Shorter splines can be cut up to 36" in diameter, either internals with up to 9" face length, or externals with longer lengths. For external, the exact length depends on the diameter of the spline and the configuration of the overall part.
