introduction：Through heating bearing[bearing:bearing（“Bearing”，Japanese person“Axial receptor”）It is a part that holds and reduces the friction coefficient of load during mechanical transmission。Can also be said，When other parts move relative to each other on the shaft，A device used to reduce the coefficient of friction during power transmission and to keep the center of the shaft fixed。]Or bearing seat，An installation method using thermal expansion to convert a tight fit into a loose fit。It is a common and labor-saving installation method。This method is suitable for the installation of cylindrical roller bearings with large interference，The bearing or separable bearing ring is evenly heated in the oil tank before hot loading80-1
