[0013] The utility model solves the shortcomings of the existing bearing seat cooling structure. Through the structural setting of the utility model, it has the following advantages: a water-cooling circulation channel is provided on the outside of the bearing to wrap the bearing, so as to cool the bearing that is working continuously. At the same time, the two water circulation chambers are alternately moved to the outside of the bearing to connect the water circulation path, so that the water in the water circulation chamber has sufficient cooling time after heat exchange, ensuring that the temperature of the cooling water does not rise, thereby improving the service life of the bearing, and the structure is simple and easy to use.
