when the tool is used, the small gear 10 is placed in the small gear positioning surface 13 of the upper plate 1, the small gear 10 is rotated at the same time, the tooth space center line of the small gear 10 is aligned to the tip II 83 of the small gear aligning device 8, the knob II 84 of the small gear aligning device 8 is rotated, the knob II 84 is aligned to the groove of the shell II 81 of the small gear aligning device 8, and therefore the tip II 83 is ejected out and is tightly ejected to the tooth space of the small gear 10. In this state, the mandrel 61 of the tension device 6 is pressed down to expand the expansion sleeve 62 of the tension device 6, the pinion 10 (as shown in fig. 9) is tensioned, and the knob ii 84 of the pinion tooth aligning device 8 is pulled out and rotated to retract the tip ii 83 of the pinion tooth aligning device 8.
Then, the bull gear 9 is placed in the bull gear positioning surface 23 of the lower plate 2, the bull gear 9 is rotated simultaneously, the center line of the tooth space of the bull gear 9 is aligned with the tip of the bull gear tooth aligning device 7, the knob I74 of the bull gear tooth aligning device 7 is rotated, the knob I74 is aligned with the groove of the shell I71 of the bull gear tooth aligning device 7, and therefore the tip I73 is ejected out and tightly pressed into the tooth space of the bull gear 9.
The complete assembly is placed on the press and the press head is pressed against the upper surface of the upper plate and moved downwards, thereby moving the pinion 10 downwards until it is pressed into the middle of the bull gear 9. When the pinion 10 is pressed into the designed position of the bull gear 9, the loosening block of the tensioning device 6 of the lower plate 2 ejects the mandrel 61 of the tensioning device 6, so that the expansion sleeve of the tensioning device 6 is loosened. The pressure head moves upwards, the strut spring 4 fixes the upper plate 1 back to be in contact with the limiting nut 3, and the small gear 10 is separated from the upper plate 1 and is connected with the large gear to form a duplicate gear assembly because the expansion sleeve 62 of the expansion device 6 is already loosened.
