5、erzahnungen of Section Antriebstechnik of the Normenausschuss Maschinenbau (NAM) (Mechanical Engineering Standards Committee) of DIN. Amendments This standard differs from DIN 5464:1965-09 as follows: a) the title has been changed to “Straight-sided splines Heavy series”; b) the tolerances specified
6、 in the withdrawn standard DIN 5465:1937-02 have been included; c) the designation has been changed. Previous editions DIN 5464: 1937-02, 1939xx-02, 1965-09 DIN 5464:2010-03 4 Introduction This standard applies to straight-sided splines with a flank angle of 0. In comparison to the specifications of
7、 DIN ISO 14, the heavy-duty series has a larger number of splines, resulting in a greater load-bearing capacity. This standard contains specifications for the geometry of these splines and for the corresponding tolerances. The general procedures for gauging and verification as specified in DIN ISO 1
8、4 also apply to the splines covered by this standard and are not included here. DIN 5464:2010-03 5 1 Scope This standard specifies requirements for straight-sided splines for fixed and moving shaft-hub connections. Straight-sided splines are particularly suitable for transmitting high torques via lo
9、w hub wall thicknesses because the flank angle of 0 prevents the hub from expanding by radial components of the flank forces. Such spline connections are normally flank-centered, but they may also be defined by additional diameter centering. 2 Normative references The following referenced documents
