Disclosed are a sealing apparatus for a gauge changing wheelset, and a gauge changing wheelset. The sealing apparatus is arranged between a sliding mechanism (3) of the gauge changing wheelset and an axle-box rear cover (2) of an axle-box body (1); the sliding mechanism (3) is axially movable relative to the axle-box body (1) and rotatable relative to the axle-box body (1); the sealing apparatus includes a sliding seal and a rotary seal; the sliding seal includes a sliding ring (4) sleeved outside the sliding mechanism (3) and hermetically connected to the axle-box rear cover (2) ; an inner wall of the sliding ring (4) is axially provided with a through groove (41), and an outer wall of the sliding mechanism (3) is axially provided with a protrusion which is slidably fitted with the through groove (41); the rotating seal includes a sealing baffle (5) fixed on an outer side of the axle-box rear cover (2); an outer wall of the sliding ring (4) is circumferentially provided with an annular groove (42), and a lower end of the sealing baffle (5) extends into the annular groove (42). The described sealing apparatus may seal between the sliding mechanism (3) and the axle-box body (1), thereby improving the sealing environment and enhancing the sealing effects.
