<p>A scraping device (13) having one or more scraping edge parts (18) is adapted to scrape ice, oil, sand and other foreign matter from a peripheral surface of a structural member, such as a shaft or a spindel (10) which may be threaded (11). The scraping device may for example have an annular shape and encircle the shaft or spindel, and the end surfaces of the device may form substantially helical surface parts (20), the adjacent ends thereof being connected by a step on which the scraping edge part (18) is formed. One or more scraping edge parts may be formed on one of the end surfaces or on each end surface. For example, at least one of the end surfaces of the scraping device may have two scraping edge parts, one of which being adapted to engage with the top (22) of the thread, the other one being adapted to engage with the bottom (23) of the thread.</p> |
