The embodiment of the invention provides a journal box. The journal box comprises a journal box bearing mounting part, and a vehicle body bearing plate fixed on the journal box bearing mounting part,wherein the vehicle body bearing plate is provided with a ventilation through hole, the ventilation through hole comprises an air inlet and an air outlet, and the air inlet and the air outlet are bothlocated in the side surface of the vehicle body bearing plate. Therefore, when a train runs at high speed, flowing air can enter the interior of the vehicle body bearing plate through the ventilationthrough hole, so that heat in the journal box is taken away, and the heat dissipation efficiency of a journal box bearing is improved.

    本发明实施例提供一种轴箱,包括:轴箱轴承安装部;车体承载板,固定于所述轴箱轴承安装部,所述车体承载板开设有通风通孔,所述通风通孔包括进风口和出风口,所述进风口和所述出风口均位于所述车体承载板的侧表面。如此,在列车高速行驶时,流动的空气可以通过通风通孔进入车体承载板内部,从而将轴箱内部的热量带走,提高轴箱轴承的散热效率。
