The requirements of the oil seal on the assembly shaft:
1. The surface roughness of the shaft is in accordance with the provisions of GB1801. The shaft surface in contact with the oil seal should be ground to a surface roughness Ra0.2 ～ 0.63um and Rmax = 0.8 ~ 2.5um.
2. The diameter tolerance of the shaft shall not exceed h11 according to GB1801.
3. The chamfer width is according to GB13871-92.
4. Surface hardness: The material of the shaft is preferably carbon steel and alloy steel. The recommended hardness is HRC45 or higher. When the medium is dirty and has contaminated impurities from the outside or the linear speed of the shaft is ≥12m / s, the surface hardness of the shaft It should be HRC50 ～ 60, and the depth of quenching layer should be ≥0.3mm.
5. The shaft is chamfered at 30 degrees (maximum). There should be no burrs, sharp corners, and spiral processing marks on the chamfer. The roughness of the chamfered surface Ra ≦ 3.2um. The heat-treated carbonized layer must be polished and removed.
ay attention:
(1) The surface roughness of the shaft is too high, and the oil seal lip is easy to wear and leak oil.
(2) Burrs, sharp corners, and spiral processing marks at the chamfers can easily scratch the oil seal lip and cause the initial seal failure of the oil seal.
(3) Avoid or reduce shaft damage, trachoma, eccentric installation and radial runout.
