Abstract
The utility model discloses an assembling labyrinth contact type oil seal for a water pump. The assembling labyrinth contact type oil seal comprises a pump shaft and a bearing body. A moving ring is fixedly arranged at the front end of the pump shaft, an outer seal ring is arranged between the moving ring and the pump shaft, a static ring is fixedly arranged at the front end of the bearing body, an inner sealing ring is arranged between the static ring and the bearing body, and annular grooves are formed in the inner side of the moving ring and the outer side of the static ring respectively. The inner side of the moving ring stretches into the annular groove in the outer side of the static ring, the outer side of the static ring stretches into the annular groove in the inner side of the moving ring, and an annular labyrinth shape groove is formed. A middle sealing ring is arranged between the moving ring and the static ring. The assembling labyrinth contact type oil seal is reasonable in structure, the moving ring and the pump shaft rotate together, the pump shaft is sealed through the outer sealing ring, the static ring and the bearing body are static, the bearing body is sealed through the inner sealing ring, and the middle ring is clamped in the gap between the moving ring and the static ring and makes close contact with the moving ring and the static ring. The assembling labyrinth contact type oil seal has the advantages of being free of leakage, long in service life, easy to assemble, low in cost and suitable for low pressure sealing of various cantilevered water pumps and other similar mechanical structures.
Description
Technical field
