Designing a Hirth Spline

18 4 Beginner
Solidworks + Excel instruction on how to design a Hirth Spline. Background on Hirth Splines: https://en.wikipedia.org/wiki/Hirth_joint The basic idea of a Hirth spline / Hirth Joint is that the whole geometry is defined from a combination of a single reference point and a grinding/cutting geometry. Two Hirth splines with the same basic tooth geometry will match to form a secure joint that can transfer torque and allows for accurate alignment of parts. Hirth splines and joints are often used in turbomachinery to accurately align various shaft parts and transfer torque.

Designing Axial Static O-ring Grooves to "Industry Standards"

6 1 Intermediate
This Covers 2/3 of everything I know about designing O-ring seals. I frequently used these while designing production tools. Most the design is based on the standards that are put forth by SAE. Personally, I be going over the reiteration by Parker since it's what I learned. Other references include the Apple Rubble Product and Trelleborg for their proprietary O-ring Gland Calculators, and the help they gave me in building my own. Links to their websites are found in Section 5. All design in this lesson is for "Static Axial Design under normal conditions”. Disclaimer: while I have completed a BS in Mechanical Engineering and have passed the FE, I am not a PE. While these calculations are standard, published, and I personally have used these practices to design multiple high-pressure tools, I cannot guarantee that they a perfect. If you are in doubt, in a hazardous environment, or using in an application that could cause harm to life, I would suggest double checking with other sources (engineering) and/or extensive testing. Also, my experience is in Oil and gas, in the continental USA. You may notice my practices being bias to API standards and in English Units, I suggest you take all I say with a grain of salt. Lesson Plan: Step 1: Background and Definitions Step 2: Finding a Published O-ring Gland and incorporating it into a design. Step 3: Designing Custom Groove using the Standards Step 4: Other Design Recommendations and Drafting Example Step 5: References and Useful links A copy of the files can be found at: https://grabcad.com/library/how-to-design-an-o-ring-gland-to-industry-standards-parts-and-photos-1
