no. 2 Embodiment approach
[0185] Hereinafter, a second embodiment of the present invention will be described based on the drawings. The tooth cutter attachment 1 of the second embodiment differs from the first embodiment only in the structure of the transmission mechanism 7 .
[0186] Figure 10 It is a transverse sectional view showing the incisor attachment 1 of the second embodiment. The transfer mechanism 7 of the second embodiment does not include the second transfer system, Figure 10 The portion shown on the left side of the middle cutter 6 is only the rotating member 73 on which the cutter 6 is mounted and supported by the cutter holder 52 via bearings.
[0187] Even the tooth cutting attachment 1 configured in this way can be mounted on the horizontal boring machine 10 and operated in the same manner as the first embodiment.
[0188] According to such a tooth cutting attachment 1 , substantially the same functions and effects as those of the first embodiment can be exhibited, and further re...
no. 3 Embodiment approach
[0190] Hereinafter, a third embodiment of the present invention will be described based on the drawings. The tooth cutter attachment 1 of the third embodiment differs from the first embodiment only in the configuration of the transmission mechanism 7 .
[0191] Figure 11 It is a transverse sectional view showing the incisor attachment 1 of the third embodiment. In this tooth cutting attachment 1, the second transmission system of the transmission mechanism 7 replaces the above-mentioned planetary gear mechanism 751, and constitutes a phase adjustment mechanism 75 with a simpler structure.
[0192] The spur gear 742C of the second rotating member 743 is formed separately from the shaft portion 742A. The spur gear 742C is coaxially inserted through the shaft portion 742A and fixed to each other by fastening a set screw 743A to the bushing portion. In such a spur gear 742C and a shaft portion 742A, by loosening the fixing screw 743A, the relative angle of the spur gear 742C wi...
