Abstract (en)
Provided are a new-type easily replaceable hob cutter system and a mounting method therefor. The system comprises a cutter holder (1) and a hob (4), the hob (4) being connected to the cutter holder (1) by means of a cutter shaft holder (2), and the cutter shaft holder (2) being fixedly connected to the cutter holder (1) by means of a telescopic tensioning mechanism (3) or a locking mechanism (5). The hob cutter system is designed to have three parts including the cutter holder, the cutter shaft holder, and the locking mechanism or the telescopic tensioning mechanism, so as to change the structure of a conventional cutter system, which makes the hob mounting, locking and removal process simpler, facilitates the automation of cutter replacement, and provides technical support for the efficient and safe "substituting labor with machine" operation mode for the cutter detection and cutter replacement operations.
