Scope

This part of GB/T 3478 specifies all the spline dimensions required for the cylindrical straight splines with 45° standard pressure angle and round tooth root (hereinafter referred to as 45° round tooth root).
This part is applicable to the splines with a pressure angle of 45°, a module of 0.25 mm to 2.5 mm, and a tooth side fit as specified in GB/T 3478.1—2008.
The dimension table in this part is compiled according to the calculation formula in Table 3 of GB/T 3478.1—2008 and adopts the basic inspection method for tooth side fit with H/h.
