Title:
BEARING BLOCK UNIT FOR RAILWAY VEHICLE
Document Type and Number:
WIPO Patent Application WO/2021/056518
Kind Code:
A1
Abstract:
A bearing block unit for a railway vehicle. A concavo-convex structure for expanding the heat dissipation area is formed in at least part of the outer peripheral surface of the bearing block unit. As such, the concavo-convex structure is capable of improving the heat dissipation capacity of the entire bearing block unit, thereby efficiently conducting heat in a bearing block (1) to the external space, and suppressing the degree of temperature rise of a bearing (2) by means of the heat dissipation of the bearing block (1). Therefore, the bearing block unit for a railway vehicle improves the heat dissipation efficiency of the entire bearing block by using a low-cost and simple structure, and inhibits the temperature of the bearing (2) from rising too fast and too high.
