The invention discloses an adjustable stern shaft rubber sealing device which comprises a stern shaft, a front end cover, a rear end cover, a sealing assembly, and an adjusting mechanism. The adjusting mechanism is additionally arranged; a driving screw rod is rotated to drive an adjusting block to transversely move, so that the adjusting block abuts against the inner end of an abutting elastic body; and when the adjusting block extrudes the abutting elastic body towards the outer end, the abutting elastic body extrudes a driving ring towards the outer side due to the force transmissibility, so that the abutting sealing ring abuts against the rear end cover more tightly, and therefore the abutting degree can be adjusted.

    本发明公开了一种可调式艉轴橡胶密封装置,包括艉轴、前端盖、后端盖、密封组件、调节机构;本发明增设了调节机构,通过旋转驱动螺杆,进而带动调节块进行横向移动,从而使得调节块对抵接弹性体的内端进行抵接,当调节块向外端挤压抵接弹性体时,由于力的传递性,使得抵接弹性体向外侧挤压驱动环,如此使得抵压密封环抵压的更加紧密于后端盖上,如此实现抵接程度的调节。
