Abstract
An apparatus for automatically assembling an inner rotor and an outer rotor substantially applied to an inscribe-type gear pump. Described is the construction and the function of the apparatus for incorporating inner rotors into outer rotors in such a manner that a holding pin which is pressed into a central hole of inner rotor descends together with the inner rotor until the accompanying inner rotor is filled into outer rotor. While the holding pin is lowered together with inner rotor, it is rotated so that gear portions of both rotors can be aligned properly and engage.
Claims10
An apparatus for incorporating an inner rotor having a gear portion around its outer periphery and a central hole provided on the central axis into an outer rotor having a gear portion around its inner periphery, comprising:
- (1) outer rotor holding means for removably holding said outer rotor in at least one predetermined position,
- (2) inner rotor holding means for removably holding said inner rotor approximately coaxially with respect to said outer rotor positioned by said outer rotor holding means,
- (3) inner rotor rotating means provided with a holding pin removably pressed into central hole of said inner rotor held by said inner rotor holding means, and provided with a rotating drive source which rotates said holding pin,
- (4) shifting means for shifting said inner rotor rotating means along the axis of said outer rotor.
