Abstract:
A magnetic disc storage system for rotatably supporting a magnetic storage disc, comprisinga base,a shaft mounted to the base, the shaft including opposed first and second bearing cones each having a crowned bearing surface that at least partially faces the crowned bearing surface of the other bearing cone,a hub rotatably mounted on the shaft for carrying the magnetic storage disc, the hub including a first conical bearing seat for rotatably cooperating with the first bearing cone and a second conical bearing seat for rotatably cooperating with the second bearing cone, the first and second bearing seats being positioned, along the length of the shaft, between the first and second bearing cones, so that the bearing seats hold the hub for rotation about the shaft, andlubricating fluid in a gap between the crowned bearing surface of the first conical bearing and the first bearing seat and in a gap between the crowned bearing surface of the second conical bearing and the second bearing seat.
