⚠️ : While some websites (e.g., idoc.pub, guifanku.com, 99jianzhu.com) may offer free uploads or shared copies of what they claim to be the "DIN5480 渐开线花键标准(中文版).pdf" (Chinese version), these are almost always unauthorized third-party uploads . We strongly advise against relying on these sources, as they often contain missing pages, contain outdated information, or include scanning errors. As an engineer, using an incorrect version of the standard could lead to costly manufacturing mistakes. Always purchase standards directly from authorized vendors.
The price for a DIN standard PDF varies by vendor and usually ranges from around €70 to €150 per part. Here are some official distributors:
Designated with lowercase letters (e.g., 7g, 8f, 9a).
Because measuring involute teeth directly is incredibly difficult, inspectors place precision pins or balls into the tooth spaces and measure the distance across them. The DIN 5480 tables provide the exact theoretical values for these measurements based on your chosen tolerance class. Din 5480 Pdf
The DIN 5480 standard defines two types of splined connections:
DIN 5480 is a widely used standard for involute splines, which are used to transmit rotational motion and torque between two shafts. The standard specifies the dimensions, tolerances, and testing methods for involute splines with a metric module.
By following these recommendations and using the DIN 5480 standard as a guide, designers and manufacturers can create high-quality splined connections that meet the required standards and regulations. ⚠️ : While some websites (e
Unlike straight-sided splines, involute splines feature curved tooth flanks similar to standard gear teeth. This profile offers several distinct engineering advantages:
Defines the basic geometric shapes, modules, reference diameters, and the 30° pressure angle. It establishes the combinations of modules and numbers of teeth.

Tolerances dictate the quality and precision of the spline profile, ranging from . Class 9 is the standard default for most industrial machinery. Tolerance Positions
DIN 5480 is a German standard for splined connections with parallel straight splines, which are used to transmit torque and rotational motion between two shafts. The standard specifies the dimensions, tolerances, and testing requirements for splined connections.
