| 摘要 |
The present invention relates to a disk section (1) for use in the construction of a grinding disk (10) such as may be used in wood hogging, chipping, or grinding apparatus. The disk section (1) is associated with a substantially wedge shaped retaining segment (30) which is positioned near the circumference of the assembled grinding disk(10), and preferentially overlaps at least part of two adjacent disk sections (1) thereon. The arrangement is such that tangential type impacts acting on a disk section (1) results in at least partial energy transmission to the retaining segment (30) and its connection (38, 39) to a hub (9).
