For
the installation of bearings, the most important thing is to correct
the way, especially the sliding bearing for the novice, especially
important. Improper installation, the bearing can not play the best results, but also affect its life. At the same time, bearing maintenance is also a composite bearing is very important, it can also affect the use of results.
installation:
1,
with kerosene to wash the bearing, into the bearing seat, bearing the
outer ring of the roller filled with Shell No. 3 lithium grease to
two-thirds full, with a clean hand evenly, fitted with ntn bearing
gland, with plus Tightening bolts for tightening bolts;
2, the bearing can be separated for the inner and outer cylindrical
roller bearings, bearings should be set in the shaft and in place;
3, the bearing seat mounted on the case, if the grease filling hole,
must be aligned with the bolt with anti-loose fastening bolts to tighten
the bearing;
4, inside and outside the eccentric block mounted on the shaft and in
place, the axis key should be the shaft key into the keyway and then
install the external eccentric block, the shaft with a ring on the
shaft;
5.
Tighten the eccentric block fastening bolts, turn the adjustable
eccentric block so that it reaches the front angular position and
tighten its fastening bolts. After the above assembly is completed, the shaft should have a certain axial chord;
6, on the vibration of the motor at both ends of the protective cover, with screws fastening;
7, running check, is able to work.
maintain:
Roller bearing maintenance, the main thing is to ensure that the
bearing lubrication, and thin oil lubrication in this area has a great
advantage.
Rare
oil lubrication: the advantages of small internal friction coefficient,
so to overcome the friction energy consumption, thin oil flow is good,
easy to enter the lubrication point of the friction surface, has a good
cooling effect, and can be attached to the friction surface Of the impurities and the metal particles produced by the grinding away. The disadvantage is that the oil film can not afford the large unit pressure, the sealing requirements are high. High-speed presses generally use large flow of thin oil lubrication, you can take away the heat generated by the friction.
