Watertight apparatus for an underwater motor

摘要

The present invention relates to a watertight apparatus for an underwater motor, comprising a double oil jacket for preventing high-pressure water from entering the underwater motor along a rotary shaft of the underwater motor. According to the present invention, high-pressure water is prevented from entering the underwater motor along the rotary shaft of the underwater motor even in the case of mechanical devices which operate in deep water, thereby preventing failure in the operation of or damage to mechanical devices caused by the ingress of water. In addition, the oil jacket can be easily replaced, thereby enabling the effective performance of maintenance and repair of mechanical devices.

主权项

1. An underwater motor watertight apparatus comprising:
an outer oil jacket configured to form a first sealing space surrounding a rotation shaft of a motor; and an inner oil jacket configured to form a second sealing space additionally surrounding the rotation shaft of the motor inside the sealing space, wherein the first and second sealing spaces are filled with oil to prevent inflow of water into a body of the motor, and wherein a screw thread is disposed on an inner wall surface of the outer oil jacket.
