摘要
A tree stump grinding wheel assembly includes a rotor having a plurality of holders distributed about its cutting periphery. Each holder has a neck in which resides a socket adapted to receive the shank of an indexable tooth. A head is attached to one end of the shank and screw threads are formed in its other end. The head has a plurality of flats configured to sequentially register with a forward shoulder on the neck. A hermetic spring is operatively disposed on the shank between a rearward face of the socket and a retention nut. The hermetic spring is made of elastomeric material and has a tapered nose that self-seats in a countersink at the rearward opening of the socket. The hermetic spring has an accordion-like bellows section. The bellows section can have a central annular bulge.
