Abstract:
The present invention relates to an indexing apparatus characterized by comprising: a driving part that is driven by a motor; and at least one driven part that rotates by engaging with the driving part. The driving part includes: a driving shaft rotated by the motor; a driving gear that is installed on the driving shaft and has driving gear teeth formed in some sections in the circumferential direction; and a driving part cam that is installed in the driving shaft so as to be on one side of the driving gear. The driven part includes: a driven shaft that is spaced apart from the driving shaft and parallel to the driving shaft; a driven gear that is installed on the driven shaft and has driven gear teeth that engage the driving gear teeth; and a driven part cam that is installed in the driven shaft so as to be on one side of the driven gear. The driving part cam has: a driving cam contact portion that contacts a driven cam contact portion while rotating; and a driving cam noncontact portion that is provided in the remaining section in the circumferential direction. The driven part cam has: the driven cam contact portion that is formed in a concave arc shape; and a driven cam noncontact portion that is provided in the remaining section in the circumferential direction. The driving gear teeth are provided in a section of the driving cam noncontact portion in the circumferential direction. Accordingly, the driven part cam and the driving part cam are not in contact with each other in a section in which the driving gear teeth are engaged with the driven gear teeth, and the driving cam contact portion and the driven cam contact portion are in sliding contact with each other in a section in which the driving gear teeth and the driven gear teeth are disengaged.
