This standard specifies the basic types and dimensions of hobs for integral involute splines with a module of 0.5mm to 10mm and a pressure angle of 30°. This standard applies to hobs for machining cylindrical spur involute splines with basic tooth profiles in accordance with GB/T3478.1 and dimensions in accordance with GB/T3478.2. Hobs are available in three precisions: A, B, and C.

3.1 This type is divided into two types: type and type. Type 1 is a flat top tool, suitable for adding 1 flat tooth external chain type is a tooth top force, suitable for "working round tooth root external chain, 3.2 The required type and size of the involute flower hob are determined by the figure! And table! 3.3 The spline is made into a single head (according to the requirements of the user): the thread is parallel to the straight line of the rolling line, 3.4 The size of the bearing is guided according to the provisions of GB/T6132. 3.5 The diameter of the bearing block is determined by the minimum manufacturing method.
