A compression-resistant structure of a deep-water propulsion motor

Abstract

The invention discloses a compression-resistant structure of a deep-water propulsion motor, which solves the problem that the seal structure of the existing deep-water motor is not scientific and reasonable and cannot meet the working requirements of the deep-water motor. The compression-resistant structure comprises a motor end cover (1) fixedly connected to the left and right end faces of the frame (2), A shielding cylinder (4) is arranged in the inner cavity of the stator (3), An annular groove (10) is provided on the inner surfaces of both motor end caps (1) on the outer side of the motorshaft, the left end of the shield cylinder (4) is fitted into an annular groove on the inner side of the left end cover, The right end of the shielding cylinder is embedded in an annular groove on theinner side of the right end cover, and the two motor end covers, the frame (2) and the shielding cylinder form a closed space (6). A tubing adapter (8) is arranged on the right end cover of the motor, an oil injection hole in the tubing adapter is communicated with the closed space (6), and a pressure-adjustable oil injection pump is connected to the tubing adapter. The compression resistance ofthe motor frame is further strengthened.

Description

technical field [0001] The invention relates to a deep-water propulsion motor, in particular to a water pressure-resistant structure of the deep-water propulsion motor. Background technique [0002] Motors for propulsion in deep water usually require the ability to resist water pressure and water seepage. At present, there are two conventional structural methods used by motors with the above functions: one is to fill the special resin into the deep water propulsion stator to fill the cavity and gap between the inside of the stator winding, the end and the frame, to achieve The role of the sealed stator makes the motor stator a solid entity to balance the hydraulic pressure outside the motor; the second is to directly fill the motor with pressure oil, and balance the deep water pressure outside the motor by adjusting the compensating oil pressure. For the first structural form, special equipment and special resin are required for potting, and the potting should be dense with...
