The editor of the three-phase asynchronous motor bearing installation method has been told to everyone in the previous chapter. Today, Dalan Motor Editor will give you a simple summary and summary of the points that need to be controlled during the bearing installation process.
(1) Use special tools as much as possible, and try to avoid using things like cloth and short fibers.
(2) When press-fitting, the assembly sleeve (copper or mild steel) made of soft metal material should be placed on the end face of the inner or outer ring of the bearing
(3) By heating the bearing or bearing sleeve, the thermal expansion is used to transform the tight fit into a loose fit installation method. It is a common and labor-saving installation method, but care should be taken to maintain the cleanliness and heating temperature during bearing heating, which is generally not easy to exceed 120 ° C.
(4) After the motor bearing is installed, it should be inspected to ensure that the bearing is installed in place, rotates flexibly, and has no seizing phenomenon. If the bearing is improperly installed, the temperature of the bearing will rise rapidly and be damaged, or even a major accident such as bearing seizure and fracture will occur.
(5) When installing cylindrical roller bearings, take the NU structure as an example, the inner circle of the bearing should be coated with grease, and the surface of the inner ring raceway should be coated with grease to minimize the installation and sleeve of the bearing. Damage between the ferrule and the roller caused by friction.
(6) When filling the grease on the oil retaining ring, the grease should be collected in the groove of the oil retaining ring against the outer raceway of the bearing as much as possible, so that the grease can be circulated normally under the appropriate amount of grease filling.
(7) When the bearing and the large end cap are about to be installed in place (when the nut is not tightened), rotate the rotor to make the self-adjustment of the possible installation of the bearing, and help to form a lubricant film inside the bearing.
