METHOD OF SETTING SEALING RINGS BETWEEN HOUSING AND SHAFT Russian patent published in 1995 - IPC

FIELD: mechanical engineering. SUBSTANCE: sealing rings are fit on the shaft. The internal space of the housing is filled with a neutral liquid. Plugs are set in the openings of the housing from the outer side of the housing. The unit and shaft are set in cooling chamber and conditioned until neutral liquid is frozen. The rod is removed from the housing, and shaft is mounted inside the housing. The plugs are detached and liquid is removed from the housing. After removing the rod from the space of the housing a lubricant is applied on the surface of the opening fitting for the shaft. A mandrel is then set over the whole length of the shaft. The groove made in the mandrel is provided with sealing ring which in size is the same as the sealing ring to be mounted. The mandrel is removed. The shaft with the sealing ring is mounted inside the housing providing integrity of the neutral liquid. The temperature of the housing is maintained at the level defined by an inequality presented in the invention description. EFFECT: enhanced reliability. 4 dwg
