Ansi B 92.1 Pdf 38 -
To help you locate your "38," here is a structural breakdown of the classic ANSI B92.1-1970 PDF:
| Section | Typical Content | Approximate Page Range | | :--- | :--- | :--- | | Foreword & Scope | Purpose, definitions, spline types | 1-5 | | Basic Formulas | Tooth thickness, space width, root fillets | 6-12 | | Pressure Angles | 30°, 37.5°, 45° design tables | 13-25 | | Tolerances & Fits | Class 1, 2, 3, 4, 5 fits (loose to close) | 26-37 | | Inspection Data | Measurement over pins formulas, pin diameter selection | 38-45 | | Tooth Thickness Tables | Internal spline space width charts | 46-65 | | Annex (Examples) | Calculations for spline design | 66-85 |
If you need page 38 specifically, you are likely looking at inspection gauging data—how to verify a spline using precision pins.
Some users mistakenly search "38" thinking of the 37.5° pressure angle spline (one of the three standard angles). It is possible the user is searching for "ANSI B 92.1 PDF 37.5" and typo'd "38." The 37.5° pressure angle is common in aerospace and heavy-duty automotive applications. ansi b 92.1 pdf 38
ANSI B92.1 defines fit classes as 4, 5, 6, and 7 (with subclasses like 5P, 6H, etc.). There is no "Class 38." Therefore, the most plausible interpretation is a direct page reference.
ASME sells the same standard. A PDF can be viewed online or downloaded with a watermark.
Imagine you are a machinist programming a wire EDM to cut an internal spline with the following specs: To help you locate your "38," here is
You need to know the pin diameter for over-pin measurement. The formula and reference tables reside on page 38 of ANSI B92.1. Without that data, you cannot QC the part.
Solution: Use the formula from the standard (which is also on page 38) or use a digital spline calculator that references the standard.
The ANSI B92.1 standard runs approximately 90–100 pages (depending on the printing or digital version). Page 38 typically falls within the dimensional data tables or inspection criteria section. Specifically, page 38 in many versions contains: Some users mistakenly search "38" thinking of the 37
If you need the exact content from page 38, you must reference the official 1996 or 2017 reaffirmed edition PDF.
If you cannot find ANSI B 92.1 PDF 38, consider these alternatives:
| Standard | Region | Key Difference | | :--- | :--- | :--- | | ANSI B92.2M | USA (Metric Module) | Uses metric modules (0.5 to 10 mm) instead of English pitch. | | DIN 5480 | Germany | Also metric, but different tooth root design. | | ISO 4156 | International | Harmonized with ANSI B92.1 for 30°, 37.5°, and 45° splines. |
Fact: ISO 4156 is nearly identical to ANSI B92.1. If you have access to ISO 4156, Table 38 will often match what you need from the ANSI version.
Because this is a copyrighted industry standard, you cannot legally download a free full PDF from just any website. However, there are legitimate ways to access the document and specifically page 38:
