Cold assembly process of rolling bearings

The bearing must be kept at room temperature, with the method of the pressure in the bearing inner ring end face, the set of parts to the shaft bearing retainer is process called cold assembly process. Parts before assembly, the shaft bearing retainer is coated with some oil, will help to assemble, as shown in figure a. Using a hydraulic press are assembled, should set position sensor or switch, a pressure sensor, such as equipment, to ensure that the pressure equipment in place, and put in place after the pressure will be revoked, in order to prevent the add more pressure on the bearing or shaft damage. As shown in figure b for the use of vertical hydraulic press, bearing a dedicated metal sleeve is placed above, for on the bearing inner ring; Figure c for vertical hydraulic press; Figure d horizontal hydraulic press, for use in the installation of bearing parts for motor rotor, an operation at the same time will be installed on both ends of the bearing. With a hammer strike to push the bearing to the desired location on the top, should be the direction of the attention, when knock is to always maintain and motor axis coincidence as shown in figure e. Figure f is self-aligning bearing with socket installation. In the absence of these conditions, can use copper bar on the bearing inner ring. Struck, with a hammer in circumferential direction with 180 ° on the, left the circulating the beat, don't too hard and hard, as shown in figure g.
