| 摘要 |
A milling drum adapted to be rotated in a cutting direction about an axis defined by the cylindrical surface of the drum. A plurality of pairs of overlapping recesses in the cylindrical surface of the drum. A tooth or cutting bit with a base configuration matching a first of the pair of the overlapping recesses, and a lower portion of a side surface including a retainer engagement feature. A retainer has a base configuration matching a second of the pair of overlapping recesses, and a side surface including a tooth engagement feature. A fastener secures the retainer in the second of the overlapping recesses so that the tooth engagement feature of the retainer engages the retainer engagement feature of the tooth or cutting bit to hold the tooth or cutting bit in the first of the overlapping recesses. |
