たことを特徴とする水中軸受保護装置。A collar fixed to the shaft is disposed facing the hub, a bearing is installed between the sliding surfaces of the hub and the shaft, and a fresh water reservoir is formed in which fresh water is press-fitted or injected into the inner peripheral surface of the knob. In the bearing protection device, a seal plate is attached to the outer peripheral end of the knob or collar, and an annular fresh water pressure pool or hydrostatic pressure pool is surrounded by the seal plate, the outer peripheral surface of the hub, and the outer peripheral surface of the collar. and the lip of the seal plate is brought into contact with the outer peripheral surface of the other collar or knob, and between the sliding surface of the shaft and the bearing surface, and between the end surface of the bearing and the inner surface of the collar. A submersible bearing characterized in that a gap is provided between the end face of the knob and the inner face of the collar, each of which performs a lubricating action and at the same time allows fresh water to form a fluid seal to pass through to the pressure reservoir. Protective device.
