Problems solved by technology

[0006] This solution only considers the instantaneous sealing effect of the lip seal ring on the end face, without further consideration that when the silicone is aging, the outer lip cannot be sealed due to the lack of upward supplementary support force, and at the same time, due to the shaking of the rudder stock, the upper end face will be damaged. The sealing effect is not good, and the vibration transmitted to the rudder stock is not slowed down by the impact of waves, inclined gravity and additional force, which can easily cause the lubricating oil in the lip seal ring to overflow

Embodiment Construction

[0027] 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.

[0028] A kind of sucker-type end face lip-shaped marine rudder stock seal, comprising a seal ring seat 7 set on the rudder stock 8, a static seal 4 is fixedly connected to the seal ring seat, and a pressure seal is pressed between the seal ring seat and the static seal. A suction cup lip seal is installed; the rudder stock passes through the rudder stock hole in the center of the static seal and seal seat, so that the static seal and seal seat are set on the rudder stock, and the center hole diameter of the static seal and seal seat is larger than that of the rudder Therefore, there is a gap between the rudder stock and the static seal and seal seat, which allows the rudder stock to swing without cont...

Abstract

The invention relates to a suction cup type end face marine rudderstock lip seal. The suction cup type end face marine rudderstock lip seal comprises a seal ring seat arranged on a rudderstock in a sleeving mode. A static seal part is fixedly connected to the seal ring seat. A suction cup type lid seal ring is pressed between the seal ring seat and the static seal part. The suction cup type lid seal ring comprises a seal ring body. The upper end of the seal ring body is integrally provided with a first lip groove and a second lip groove from inside to outside in sequence. An annular buffer squeeze groove is integrally formed in the seal ring body between the first lip groove and the second lip groove. A plurality of springs are uniformly inlaid in the annular buffer squeeze groove at intervals. The suction cup type end face marine rudderstock lip seal is provided with a suction cup type sealing vibration reduction end face and has the advantages of greatly improving the sealing effecton the rudderstock, reducing vibration sensitivity and protecting the surface of the rudderstock against abrasion.

Description

technical field [0001] The invention belongs to the field of ship rudder systems, and relates to a rudder stock rudder bearing sealing technology, in particular to a sucker-type lip-shaped marine rudder stock seal. 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 ...
