Abstract
The invention discloses multiple bearings of an elongated tailshaft, comprising a screw shaft on which a propeller, a rear bearing, a middle bearing, a front bearing and a screw shaft coupling which are respectively and sequentially arranged, wherein the rear bearing and the front bearing are respectively connected with tail seal oil and front seal oil which are respectively arranged on the screw shaft; bearing steel castings are respectively fixed on the rear bearing, the middle bearing and the front bearing via adjustable bolts; the bearing steel casting on the rear bearing is provided with a protection cover; the rear bearing and the middle bearing are connected via a first shaft tube; the middle bearing and the rear bearing are connected via a second shaft tube; and the rear bearing, the middle bearing and the front bearing are all provided with epoxy pouring holes and breathers. In the invention, the elongated tailshaft is provided with three bearings and the selection of bearing positions and bearing gaps as well as the installation precision in the installation process can be determined by precise calculation, and the design in the invention has profound and lasting significance on design and construction of an elongated shaft ship in the future.
Description
Technical field
The present invention relates to a kind of elongated tailing axle multiple bearing, be used for boats and ships.
Background technology
Adopt the single tail pipes of duplex bearings at present on the domestic and international same tailing axle, three bearings are contained in also not adopting on the tailing axle more.
Summary of the invention
The objective of the invention is in order to overcome above deficiency, a kind of simple in structure, a kind of elongated tailing axle multiple bearing that cost is low is provided.
Purpose of the present invention is achieved through the following technical solutions: a kind of elongated tailing axle multiple bearing; comprise stern tube shaft; screw propeller is installed respectively on the described stern tube shaft successively; rear bearing; centre bearer; front bearing; the stern tube shaft plunging joint; described rear bearing; front bearing is connected with the tail Seal Oil respectively; preceding Seal Oil; described tail Seal Oil and preceding Seal Oil are installed on the stern tube shaft respectively; described tail Seal Oil is between screw propeller and rear bearing; Seal Oil is between front bearing and stern tube shaft plunging joint before described; described rear bearing; centre bearer; all bearing steel castings is arranged on the front bearing by regulating bolt; on the bearing steel castings on the described rear bearing protective case is housed; described rear bearing links to each other by the first stern pipe with centre bearer, and described centre bearer links to each other by the second stern pipe with rear bearing.Described rear bearing, centre bearer, front bearing all have epoxy casting hole and breather hole.
The present invention has the following advantages: be provided with three bearings, and the selection of position of bearings and bearing space choose with installation process in setting accuracy, all pass through accurate calculating, this design will produce profound significance to the design and the construction of later slender axles boats and ships.
Description of drawings:
Fig. 1 is a structural representation of the present invention;
Number in the figure: Seal Oil, 8-bearing steel castings, 9-protective case, the 10-first stern pipe, the 11-second stern pipe, 12-regulate bolt, 13-screw propeller, 14-epoxy casting hole, 15-breather hole before 1-stern tube shaft, 2-rear bearing, 3-centre bearer, 4-front bearing, 5-stern tube shaft plunging joint, 6-tail Seal Oil, the 7-.
The specific embodiment:
In order to deepen the understanding of the present invention, the invention will be further described below in conjunction with embodiment and accompanying drawing, and this embodiment only is used to explain the present invention, does not constitute the qualification to protection domain of the present invention.
Show a kind of elongated tailing axle multiple bearing of the present invention as Fig. 1; comprise stern tube shaft 1; screw propeller 13 is installed respectively on the stern tube shaft 1 successively; rear bearing 2; centre bearer 3; front bearing 4; stern tube shaft plunging joint 5; described rear bearing 2; front bearing 4 is connected with tail Seal Oil 6 respectively; preceding Seal Oil 7; tail Seal Oil 6 and preceding Seal Oil 7 are installed respectively on the stern tube shaft 1; tail Seal Oil 6 is between screw propeller 13 and rear bearing 2; Seal Oil 7 is between front bearing 4 and stern tube shaft plunging joint 5 before described; rear bearing 2; centre bearer 3; all be fixed with bearing steel castings 8 on the front bearing 4 by regulating bolt 12; on the bearing steel castings 8 on the described rear bearing 2 protective case 9 is housed; rear bearing 2 links to each other by the first stern pipe 10 with centre bearer 3, and centre bearer 3 links to each other by the second stern pipe 11 with rear bearing 4.Rear bearing 2, centre bearer 3, front bearing 4 all have epoxy casting hole 14 and breather hole 15.Each bearing when mounted, the centre bearer 3 of stern tube shaft 1 should fully take into account the whirling vibration of axle system along the location of axis direction, should decide the position of centre bearer 3 in conjunction with the distribution condition of bearing load according to the requirement of whirling vibration of shafting calculation sheet.Bearing space is too small, and not only axle system load increases, and can quicken the wearing and tearing of this bearing, but bearing space is excessive, and is little to the whirling vibration effect that reduces axle system.After tail pipe connected, centre bearer 3 was not easily with the straight line degree measurement of front bearing 4 and rear bearing 2, so how require just particularly importantly from designing when guaranteeing to install the right alignment of three bearings, when working out mounting process, must consider this point yet.The present invention is provided with three bearings, and the selection of position of bearings and bearing space choose with installation process in setting accuracy, all pass through accurate calculating, this design will produce profound significance to the design and the construction of later slender axles boats and ships.
