Provided is a gear shaving
machining tooth form modification method. The method is characterized in that reverse
cutting is conducted on a gear shaving cutter by means of
a diamond dressing wheel, the
tooth surface of the gear shaving cutter is concave, a gear is machined through the gear shaving cutter with the concave
tooth surface, the concave phenomenon can be eliminated; the form modification comprises the steps that 1, the
diamond dressing wheel is customized, the number of teeth of the dressing wheel is selected according to the specific
mode number and
tooth number of the gear product; 2, the dressing wheel is installed on a gear shaving
machine to replace a workpiece gear, the dressing wheel is subjected to
cutting machining by using the gear shaving cutter needing to be modified, and the tooth form surrounding the gear shaving cutter reference circle is concave; 3, nitridation treatment is conducted on the modified gear shaving cutter; the shape of the
diamond dressing wheel is the same as that of the product gear, and the
gear tooth surface of the customized
diamond dressing wheel is coated with
a diamond particle layer. By
machining the gear through the gear shaving cutter modified through the method, the concave phenomenon in the tooth form obtained after gear shaving machining can be effectively solved, the yield of gear parts is guaranteed, and the use efficiency of the gear shaving cutter is improved.
