In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", "positive", "negative", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present invention.
Please refer to the description of the present invention shown in fig. 1 to 5.
The ship shafting comprises a transmission shaft, bearings, shafting accessories and the like, wherein the transmission shaft is generally long and can be divided into a thrust shaft, an intermediate shaft, a stern shaft or a propeller shaft, the bearings are correspondingly divided into a thrust bearing, an intermediate bearing and a stern bearing, and the shafting accessories comprise a lubricating device, a cooling device, a stern shaft sealing device and the like. Fig. 1 shows a multi-bearing transmission shaft, which is generally divided into several sections, and the sections are connected and combined by a coupling, and each section is divided into a thrust shaft, an intermediate shaft, a stern shaft or a propeller shaft according to different bearing tasks, and the sections are supported by corresponding bearings. The total length of the propeller shaft, the number of shaft sections and the arrangement of their attachments are dependent on factors such as the size of the ship, the shape of the ship, the line type of the hull, the location of the engine room, the form of the power plant, etc. For small ships with short axial lines, in order to shorten the shafting, only one propeller shaft can be used for directly connecting the propeller with the output flange of the gear box. The present invention is described in detail with reference to a stern shaft which generates thrust.
The first embodiment is as follows: as shown in fig. 2 and 3, the stern shaft 100 (fixed shaft) includes a stern shaft bearing 30, a nacelle 10 installed at the distal end of the stern shaft 100, and a blade assembly 20 installed between the stern shaft bearing 30 and the nacelle 10. Blade assembly 20 includes a blade 201 and a hub 202 integrally formed with blade 201; the air guide sleeve 10 is fixedly connected with the hub 202 through a first bolt 103; the gap formed between the guide sleeve 10 and the tail end of the stern shaft 100 is a lubricating area 102, grease can be injected inwards from an injection hole 101 at the side of the lubricating area 102, so that the lubricating effect is achieved, and the seawater infiltration is effectively isolated and the corrosion is avoided by utilizing the water-oil incompatibility principle.
Specifically, in the present embodiment, the arrangement of the air guide sleeve 10 not only can improve the wake flow of the fixed blade and avoid the influence of the accelerated water flow during the ship advance, but also can improve the stability of the fixed blade operation. In addition, the front end of the air guide sleeve 10 is fixedly connected with the stern shaft 100 through a plurality of bolts, so that the fixing effect of the air guide sleeve 10 on the tail end of the stern shaft 100 is strengthened, and meanwhile, the water is prevented from infiltrating and corroding the stern shaft during operation in water. The injection hole 101 is arranged at the concave part of the guide cover 10 towards the stern shaft 100, when grease is injected through the injection hole 101, the injection hole 101 is firstly sealed by a cock 111, and then the injection hole 101 is further sealed by quick-drying cement or other quick-drying materials, so that the grease in the lubricating area 102 is prevented from leaking and external water is prevented from permeating. Particularly, the lower part of the cock 111 is provided with the measuring column 121, so that an assembler can plug the cock 111 with the measuring column 121 in due time when injecting the grease, confirm the grease injection condition, avoid insufficient injection and achieve the grease injection effect; or overfill and overflow, wasting material and increasing cleaning procedures. In this embodiment, the cock 111 with the measuring column 121 is an integrally formed structure, and has a shape that is wide at the top and narrow at the bottom.
Example two: a difference from the exemplary embodiment is that the lubricating region 102 can also be filled with other lubricating materials or combinations of lubricating materials.
Example three: a difference from the embodiment is that the pod 10 may take on different shapes and configurations, and may be a cone or other regular or irregular shaped closure.
Example four: the difference from the embodiment is that, as shown in fig. 4-5, the measuring column 121 and the cock 111 are separate structures, a clamping groove is formed at the lower part of the cock 111, the measuring column 121 is provided with a clamping plate 131, and the clamping plate 131 is clamped in the clamping groove at the lower part of the cock 111 during assembly. Therefore, the measuring column 121 can be clamped on the cock 111 according to actual requirements, and the measuring column 121 can be detached from the cock 111 under the condition that the lubricant injection is confirmed to be completed through the measuring column 121, so that the measuring column 121 can be recycled conveniently.
Example five: the difference between the first and fourth embodiments is that the magnet is arranged on the card board 131 above the measuring column 121, and when in use, the lower part of the cock 111 and the card board 131 are wiped clean, and the card board 131 with the magnet is adsorbed below the cock 111. Such a measuring column 121 has a stronger applicability, does not require to change the structure of the original cock 111, and is also applicable to different cocks 111, which is more convenient for actual assembly.
The above list of details is only for the practical implementation of the present invention, and they are not intended to limit the scope of the present invention, and all equivalent implementations or modifications that do not depart from the technical spirit of the present invention should be included in the scope of the present invention.
Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
