At this point, the gear only exists in the computer as a set of mathematical parameters, along with data on the desired contact conditions between the two gears and their desired uniformity-of-motion.

The software helps the engineer develop and optimize gear tooth geometry of bevel and hypoid gears based on customer application requirements.Īs part of the design process, the analysis portion of the software predicts how the theoretical gear will mesh with its mating gear, so the engineer can “test” gearset performance before any metal is cut. Using Gleason’s design and analysis software package, called CAGE (Computer-Aided Gear Engineering), the design engineer enters basic gear parameters, such as number of teeth, diametral pitch, and face width. The first step in the closed-loop process is to establish an optimum theoretical gear design. The late ‘80s brought enhancements such as graphic capabilities, and multi-tasking, letting users perform these tasks on desktop workstations. Users could move sequentially through design and analysis programs to calculate machine settings for an optimum gear design. In the early 1980s, The Gleason Works, Rochester, N.Y., developed the software for this closed loop system: a gear design and analysis package that was available to gear manufacturers online, via modem. Gear evaluation, using software to verify that the generated gear matches the design.
Machine settings (CNC program) for the gear-generating machine.Gear design, using software that analyzes the tooth surfaces and their mating contact characteristics before parts are generated.Now, an integrated, closed-loop gear development and manufacturing system brings the three key elements of this process together so gear manufacturers can perform the trial-and-error steps more efficiently, thereby reducing the time from days to hours, and minimizing the potential for human error. But still, this trial-and-error process takes several days. Over the years, advances in computers and software have eliminated much of the tedium involved. And they often must repeat the entire process more than once to obtain a dimensionally acceptable gear. Gear manufacturers must go through a trial-and-error process of design, prototype manufacture, inspection, and adjustment of machine settings to refine the part geometry.

The complex geometry of spiral bevel and hypoid gears makes it a tedious, timeconsuming process to turn a gear design into a finished product that works as intended.
