Embodiment Construction

[0030] The present invention will be further described in detail below in conjunction with the accompanying drawings and through specific embodiments. The following embodiments are only descriptive, not restrictive, and cannot limit the protection scope of the present invention.

[0031] A double-sided lip-shaped sealing ring for a marine rudder stock, comprising a sealing ring body 1, an inner hole 9 of the sealing ring is provided at the center of the sealing ring body, the rudder stock is inserted in the inner hole of the sealing ring, the middle part of the sealing ring body is closed, and the seal The upper end and the lower end 11 of the ring body are respectively coaxial, back-symmetrical, and obliquely extended to the outside. An upper inner lip 3, an upper outer lip 2, a lower inner lip 18, and a lower outer lip 16 are integrally formed. The sealing surface where the sealing ends of the upper outer lip and the upper outer lip are located is perpendicular to the centerl...

Abstract

The invention relates to a marine rudderstock double-sided lip seal ring which comprises a seal ring body. An upper inner side lip and an upper outer side lip as well as a lower inner side lip and a lower outer side lip are integrally arranged at the upper end and the lower end of the seal ring body in a coaxial opposite-symmetrical outwards-inclined extending way; a sealing surface on which the lip sealing end between the upper inner side lip and the upper outer side lip is located is perpendicular to a seal ring inner hole, and a sealing surface on which the lip sealing end between the lowerinner side lip and the lower outer side lip is located is perpendicular to the seal ring inner hole, so that a double-sided end surface sealing structure is formed; sloping bench ring surfaces are integrally arranged on one sides, close to the seal ring inner hole, of the top parts and the bottom parts of the upper and lower inner side lips; a stainless steel strengthened ring is arranged in themiddle of the peripheral rubber of the seal ring body; and polytetrafluoroethylene seal rings are arranged in the sloping bench ring surfaces. The marine rudderstock double-sided lip seal ring provided by the invention adopts a double-sided lip sealing structure so as to be good in rudderstock sealing effect, less in vibration sensitivity, and less in rudderstock surface wear.

Description

technical field [0001] The invention belongs to the field of ship rudder systems, and relates to a seal ring, in particular to a double-sided lip-shaped seal ring for a ship rudder stock. Background technique [0002] The rudder stock is the vertical shaft for the rotation of the rudder blades, and is an important structural part of the ship's rudder system; it is used to bear and transmit the force acting on the rudder blades and the force that the rudder gives to the rudder steering device. Therefore, the rudder stock not only transmits the rotational moment of the rudder blade from the steering gear, but also bears the reaction force of the water body on it, as well as the impact and additional force of waves and inclined gravity on it. The rudder stock seal mainly prevents seawater from entering the hull through the rudder stock through the position of the hull, so as to prevent damage to the structural components of the cabin device, and also to prevent the double funct...
