FIELD: chemistry.
SUBSTANCE: invention relates to construction of axial butt end sealing, made with possibility of joint rotation with drive shaft in rotary device, and axial butt end sealing, containing main element (1) and mobile part (2), and main element (1) is made with possibility of connection with drive shaft for joint with it travel, mobile part (2) has sealing butt end surface (3) and has possibility of travel in axial direction relative to main element (1), and is displaced from main element (1) by means of spring (4), and mobile part (2) and main element (1) contain interacting means (14, 15) of transmission of torque for joint rotary travel of mobile part (2) with main element (1), and means of torque transmission contain, at least, one finger (14) for torque transmission and, at least, one corresponding hole (15), into which said finger (14) for torque transmission is inserted with possibility of displacement, and, at least, one finger (18) for protection against wearing is located between said finger (14) for torque transmission and said hole (15) near the border of transmission of power of means (14, 15) of torque transmission.
EFFECT: improvement of construction.
