oil seal tc type installation

Oil seal tc type is a combination of gasket seals used to seal oil mechanically, oil seal tc type transmission parts need to be lubricated parts and output parts isolated, so as not to let the oil leakage.Oil seal tc from the sealing role, characteristics, structural type, working state and sealing mechanism can be divided into a variety of forms and different terms.

Under the action of liquid surface tension, the stiffness of oil film just makes the oil film and air contact end form a crescent surface, prevent the leakage of working medium, so as to achieve the rotating shaft seal.The sealing ability of oil seal, depends on the thickness of the oil film seal, the thickness is too large, oil seal leakage: the thickness is too small, may occur dry friction, causing oil seal and shaft wear;There is no oil film between seal lip and shaft, it is easy to cause heat, wear.Therefore, in the installation, it is necessary to put some oil on the combination washer, while ensuring that the skeleton oil seal and the axis vertical, if not vertical, oil seal lip will drain the oil from the axis, it also causes excessive wear on the oil seal lip. During operation, the lubricant in the shell seeps a little, so that the oil film is formed at the sealing surface of the skeleton oil seal.

*tc seal sealing principle:This is a completely rubber-coated oil seal with self-tightening spring of the double-lip skeleton,because of the oil film controlled by the oil seal edge between the oil seal and the shaft, the oil film has the characteristics of fluid lubrication.
