The DIN 5462 profile relies on a straight-sided tooth geometry where torque is transmitted along the flat flanks of the teeth. The standard specifically details dimensions for the internal spline (hub) and the external spline (shaft). 1. The 8x32x36 Profile
If you want to finalize your design or source components, let me know:
Originating in the mid-20th century, DIN 5462 was first published in 1939, with the most widely recognized version, , becoming a cornerstone of German industrial engineering. Its full title, "Spline Shaft Connections with Straight Flanks; Light Series," immediately reveals its scope: it defines the dimensions, tolerances, and design philosophy for straight-sided splines intended for applications with lower to moderate torque requirements. The standard was the brainchild of the German Institute for Standardisation (Deutsches Institut für Normung – DIN) , an organization that has shaped global engineering practices for over a century. din 5462 spline standard pdf exclusive
Do you need the for a sliding fit or a fixed fit? What is the operating torque or RPM of your system? g., Bosch Rexroth, Parker)?
One element often missing from free online calculators is the centering instruction . DIN 5462 requires manufacturers to explicitly state whether centering is on the major diameter (D), minor diameter (d), or flanks (b). The PDF standard contains the exact flowcharts for these designations.
The chart below illustrates the relationship and evolution of these spline standards. If you need further help with this standard,
: Leading fluid power manufacturers (such as Bosch Rexroth, Parker, and Casappa) produce gear pumps and piston pumps featuring DIN 5462 8-tooth drive shafts.
SAE spline standards (such as SAE J744 and SAE J498) are widely used in the automotive and off-highway industries. Many PTO (power take-off) systems combine both standards on a single component. For example, some hydraulic pumps feature a with an SAE spline shaft , or vice versa.
The "exclusive" part of the title wasn't a marketing buzzword. It referred to a specific, non-interchangeable geometry designed for a single purpose: the "Chronos Drive," a failed experimental engine from the late 1950s. Unlike standard splines that used a 30° pressure angle The 8x32x36 Profile If you want to finalize
DIN 5462 is part of a broader family of German spline standards that cover different load capacities. The three main standards are:
The you are trying to calculate (e.g., sliding fit vs. tight fit)
Understanding DIN 5462 is crucial for designers, manufacturers, and maintenance professionals involved with Power Take-Off (PTO) shafts, hydraulic pumps, and gearboxes. 1. What is the DIN 5462 Standard?
The standard specifies the dimensions and tolerances for straight-sided (parallel) metric splines in the "light series". While the original DIN 5462 standard is technically superseded by DIN ISO 14 , it remains the primary industry reference for hydraulic pumps and power take-off (PTO) units, particularly the common 8 x 32 x 36 profile.
