Abstract
The utility model provides a ship stern tube structure, which comprises a front and rear stern shaft seats (5,3) for mounting a stern shaft (2), a sealed cooling water cabin (4) between the front and rear stern shaft seats, and a stern tube (8) sleeved outside the stern shaft, wherein the front and rear ends of the stern tube are respectively connected with the front and rear stern shaft seats via flanges, the outer wall of the stern tube between the front and rear stern shaft seats exposes to the inside of the cooling water cabin, and the front and rear ends of the stern tube are in sealed joint with the front and rear stern shaft seats via epoxy resin and sealant. The utility model breaks the convention of covering a stern tube with an outer casing pipe, saves the outer casing pipe, and enables the stern tube to directly contact with the cooling water in the cooling water cabin. When the stern shaft rotates at high speed, the liquid coolant between the stern tube and the stern shaft plays an important role of cooling, while the cooling water in the stern tube cooling water cabin cools the liquid coolant and plays a helping role. When the outer wall of the stern tube directly contact with the cooling water, cooling of the cooling water to the liquid coolant can be speeded up.
Description
Technical field the utility model relates to a kind of stern tubular construction of boats and ships stern tubular construction, especially large ship, belongs to the technical field of structures of the propulsion system of boats and ships in the transportation.
The marine shafting stern tubular construction that background technology is traditional mainly is made up of stern tube shaft, stern pipe, stern pipe outer tube, stern tube shaft front and rear bushings, oil filling device, stern cooling water tank, front and back stern tube shaft base, floor etc.Before and after particularly being weldingly fixed between the stern tube shaft base, be enclosed within the stern pipe outer tube of stern tube outside, it is considered to be used for increasing the intensity of stern pipe assembly, and protection stern tube shaft, stern pipe institute are indispensable.But find that in actual use the stern guard system sends temperature alarm sometimes.The major cause analysis is, stern tube shaft is in the high speed revolution process, the heat that stern tube shaft and stern tube shaft front and rear bushings cliding friction produce, a part is taken away by the cooling and lubricating circulating system, some then is dispersed into the stern tube outside by the stern pipe, and a stern pipe outer tube has been overlapped in the stern tube outside, make and form an enclosed cavity between stern tube outer surface and the stern pipe outer tube inside face, although stern pipe outer tube outside face has cooling media, but because of this enclosed cavity internal memory has air, it is a bad conductor, so cold and hot exchange effect is relatively poor, has caused the cooling performance of stern tubular construction not good enough.Will send temperature alarm if meet reasons such as stern tube shaft high speed rotating overlong time or coolant temperature uprise a little, untimely elimination, then will cause axle is the badly damaged of propulsion system, or has reduced service life.
Summary of the invention is at above deficiency, and the utility model is exactly the boats and ships stern tubular construction that will improve cooling performance under the prerequisite that guarantees stern pipe intensity.
Boats and ships stern tubular construction of the present utility model has the front and back stern tube shaft seat that stern tube shaft is used is installed, and a leak free cooling water tank is arranged between the stern tube shaft seat of front and back; Have one to be enclosed within the outer stern pipe of stern tube shaft, stern pipe rear and front end connects with front and back stern tube shaft base by flange, wherein is fixedly connected with back stern tube shaft base, with preceding scalable connection of stern tube shaft base; The neck flange of stern pipe rear and front end flange is connected as former and later two linings of plain bearing and stern tube shaft; The refrigerant fluid interlayer is arranged, and the oil filling pipe of stern tube shaft rear end is arranged in this refrigerant fluid interlayer between stern pipe and stern tube shaft; The outer wall of described stern pipe between the stern tube shaft seat of front and back is exposed in the cooling cabin, is tightly connected by epoxy resin and sealant between stern pipe front and back end and the front and back stern tube shaft base.
Boats and ships stern tubular construction of the present utility model overcomes old opinion that stern pipe that prior art thinks also needs to overlap a stern pipe outer tube, has cancelled this stern pipe outer tube, make the stern pipe directly and the interior cooling cooling water expansion tank of cooling cabin contact.When the stern tube shaft high speed rotating, play main cooling effect by the refrigerant fluid between stern pipe and the stern tube shaft, and rise the cooling effect of refrigerant fluid and the cooling effect of assisting with the cooling water expansion tank in the stern pipe cooling water tank.When stern pipe outer wall directly contacts with cooling water expansion tank, just quickened the cooling of cooling water expansion tank to refrigerant fluid.
In addition, in the prior art as the front and back stern tube shaft seat that supports the stern pipe simultaneously, they not only with hull on the floor welding fixing, and need respectively with the tight welding in the two ends of stern pipe outer tube to play an effect of isolating cooling water expansion tank and axle system.In order to reach requirements for qualitys such as welding deformation is little, welding stress is little, the wall thickness of stern tube shaft seat and stern pipe outer tube joint is should gap little, so the stern tube shaft base has a bigger wall thickness change at this place.This not only makes casting process, the metalworking process complications of stern tube shaft base, and the installation of stern pipe unit is made troubles, and welding quality also is difficult to guarantee.After having cancelled stern pipe outer tube, the wall thickness change of said stern tube shaft seat does not just need, and this has not only saved material, the processing of stern pipe outer tube itself, the consumption of installation, also saved to the stern tube shaft base because of required casting, the processing of installation stern pipe outer tube.The utility model stern tubular construction provides a kind of and can guarantee stern tube shaft system normal operation in a word, and have that technology is simple, easy construction, effective, axle system that simultaneously can the saving in material cost-cutting.
Boats and ships stern tubular construction of the present utility model, be lined with epoxy resin between the neck outer wall of stern pipe front and back end and institute's flange connecting and the front and back stern tube shaft base axis hole, before having an epoxy resin layer back-up ring to be installed in fastener, preceding stern tube shaft base front side on the stern tube shaft base, also have a seal ring to be subjected to the back-up ring compressing in the gap between neck flange and the preceding stern tube shaft base axis hole to guarantee leak tightness.
Boats and ships stern tubular construction of the present utility model has a sealing member between the axis hole of one side of front and back stern tube shaft base sensing cooling cabin and the stern pipe front and back end outer wall.
Boats and ships stern tubular construction of the present utility model, front and back stern tube shaft base length is separately crossed over the twice floor with fixing with the welding of twice floor respectively, improved and originally needed the design that a partial floor fixes the stern tube shaft seat, make that (partial floor i.e. floor between two floors because of welding processing difficulties that partial floor caused is eliminated, because of the hypotelorism between partial floor and the floor, relatively more difficult when causing welding, and may influence welding quality), further simplify the installation of stern tube shaft system.
