Abstract
The invention relates to an expansion bearing remover. The expansion bearing remover comprises an end face supporting base and a plurality of clamping jaws arranged on the end face supporting base in an annular array. The clamping jaws are rotationally connected with the end face supporting base. A supporting plate is arranged in the middle of the end face supporting base. A pull rod is arranged on the supporting plate through a through hole and is a threaded rod. One end of the pull rod is provided with a pulling head with the diameter larger than that of the through hole. The threaded rod is further sequentially provided with a push ring, a push ring ejector block, a bearing pushing mechanism and a bearing pushing mechanism ejector block. The side, corresponding to the interior of the end face supporting base, of each clamping jaw is provided with a push arm. The periphery of the push ring is provided with an annular push face. The bearing pushing mechanism comprises a supporting block connected with the pull rod in a sliding mode. The supporting block is rotationally connected with an ejector rod. The pull rod is further provided with a sliding sleeve. The sliding sleeve is provided with a rack. The rotary connection end of the ejector rod is provided with a plurality of tooth grooves. The rack is matched with the tooth grooves to drive the ejector rod to rotate.
