The utility model relates to a heating device for a temperature difference method sleeved bearing, in particular to a construction site bearing heating device which comprises an oil tank, engine oil is contained in the oil tank, two electric heaters and a thermal resistor are installed on the side portion of the oil tank, and a speed reducer, a motor and a stirring shaft are installed on an end cover on the top of the oil tank. The rolling bearing is hung on a bearing hanging ring in the oil tank, engine oil is heated through the electric heater, the bearing is heated through the engine oil, the inner diameter of the bearing is expanded, after the temperature of the engine oil reaches a set value, the automatic temperature control device stops heating the engine oil, the bearing is taken out and arranged on a main shaft of transmission equipment in a sleeving mode, and the bearing sleeving process is completed through a temperature difference method. The bearing assembling tool is simple to operate, safe and
