Method for preparing a lip type shaft seal for a shaft for underwater use, method for installing a lip type shaft seal on a shaft for underwater use and lip type shaft seal for a shaft for underwater use

摘要

The present invention relates to a method for preparing a lip type shaft seal (20, 40, 50) for a shaft for underwater use, a method for installing a lip type shaft seal on a shaft for underwater use, and a lip type for a shaft for underwater use. It relates to a shaft seal. The present invention includes a discontinuous point having a foam lock element (246, 266) such that the use of the foam lock element (246, 266) without the use of habitat can actually place a seal around the shaft in water. It is particularly advantageous to provide a lip type shaft seal.
