Abstract
A shield machine hobbing cutter with a double sealing structure belongs to the shield machine cutter field and is a significant fitting of a shield machine. The shield machine hobbing cutter is characterized in that two inner end covers are equipped inside step holes on the two ends of a housing through the external diameter; a right end cover is equipped on the right end of a hobbing cutter shaft through an inner hole of the right end cover; a left end cover is equipped on the left end of the hobbing cutter shaft through an inner threaded hole of the left end cover; and a first rubber ring, a second rubber ring, a small special sealing steel ring and a large special sealing steel ring are installed inside conical holes respectively equipped on the inner end covers, the right end cover and the left end cover and correspondingly symmetrical with the right end cover, the left end cover and the inner end covers. By adopting the above-mentioned double sealing structure, the shield machine hobbing cutter which enables sealing stability and deeper underground construction is conducive to improving the service lifetime of a bearing.
Description
Technical field
Having the shield machine roller cutter of double sealing structure to belong to the shield machine cutter field, is the important accessory of shield machine.
