Not for dentists 🦷

In the past recent months, the material review board (MRB) worked on a part mating problem but not quite sure what the root cause is due to because profiles of gear teeth is no suitable for linear measurement tools or even CMM. The next best equipment is a Go NoGo spline gage thereby the need to look up the reference on gear splines production and inspection.

ANSI B92.1 is a standard published by the American National Standards Institute (ANSI) that focuses on the design, production, and inspection of cylindrical involute gears.

1. Gear Design: ANSI B92.1 provides specific guidelines for gear design, including tooth profiles, dimensions, and tolerances. One must understand these design specifications to ensure that gears are fabricated correctly and the GO-NOGO gages to match them as well.

2. Material Selection: The standard also outlines the acceptable materials for gear manufacturing. It is crucial for ME and PE as well as quality engineers to be aware of these material requirements for the pair of GO-NOGO gages and the importance of using materials that able to withstand the actual splined shaft and levers.

3. Quality Control: ANSI B92.1 sets forth rigorous quality control procedures, including gear inspection and testing. The team need to understand how to generally inspect gears to ensure they meet the standard’s criteria. This may involve measuring tooth profiles, checking for defects, and performing hardness tests.

4. Documentation and Record-Keeping: Keeping accurate records of gear specifications, manufacturing processes, and inspection results is a vital aspect of adhering to ANSI B92.1. The GO, NO-GO gage supplier also has to confirm with the MRB team before making it.

5. Collaboration with Gear Manufacturers: In many cases, control valve assembly plants work in collaboration with gear manufacturers to source the required components. Aside from part drawings of mating parts we to understand how to communicate these requirements to gear manufacturers and ensure that the delivered gears conform to ANSI B92.1.

Back to the real world 🗺️, happy Monday to us all.

Cheers 🥂 MFR
