Which assembly method is used for tapered roller bearing of locomotive axle box?
Assembly methods include cold assembly method and hot assembly method.

1. cold assembly method: the cold assembly method is to press the tapered roller bearing on the shaft with a press and an auxiliary device. This method is suitable for large interference. During cold assembly, do not directly hit the bearing end face with tools to avoid damaging the bearing.

2. Hot assembly method: The hot assembly method is to heat the bearing to expand its inner diameter, and then install it on the shaft. This method is suitable for small interference. During hot assembly, the heating temperature should not exceed 120℃.
