Abstract

The utility model discloses a kind of stern pipe false bearings of plug stern tube shaft：Including bearing body, bearing body sets sector notch, and sector notch inner wall is inlaid with arc copper bar；Bearing body is mounted on the inside of stern pipe, and sector notch is arranged concentrically with stern pipe, and the inner wall of arc copper bar and the outer wall of stern tube shaft match.The arc copper bar of the utility model is directly contacted with stern tube shaft, since there is arc copper bar good self-lubricating property, bearing body not only can play good positioning and supporting role to stern tube shaft, will not also cause to wear to stern tube shaft, and its cost is also very low.

Description

Fill in the stern pipe false bearings of stern tube shaft

Technical field

The utility model is related to shipbuilding technical fields, and in particular to a kind of stern pipe false bearings of plug stern tube shaft.

Background technology

Shafting lifts and propeller installation is important process in shipbuilding, wherein by propeller shaft from cabin toward machine Stern pipe is filled in out of my cabin, i.e., the so-called step filled in stern tube shaft and be more crucial.Usually, during filling in stern tube shaft, stern tube shaft only leans on Hoist cable is suspended in stern pipe, and the bearing between stern pipe and stern tube shaft is also not acted upon, and needs the inside mounting process dummy shaft in stern pipe It holds, be used as to position and support, to ensure being smoothed out for plug stern tube shaft.Therefore the stern pipe dummy shaft bearing structure of reasonable design, to filling in stern Axis, which is smoothed out, to be of great significance.

Utility model content

In order to ensure to make stern tube shaft smoothly to fill in stern pipe, the utility model provides a kind of stern pipe dummy shaft of plug stern tube shaft It holds.

The technical solution adopted in the utility model is as follows：

A kind of stern pipe false bearings of plug stern tube shaft：Including bearing body, the bearing body sets sector notch, the sector notch Inner wall is inlaid with arc copper bar；The bearing body is mounted on the inside of stern pipe, and the sector notch is arranged concentrically with stern pipe, the arc The inner wall of shape copper bar and the outer wall of stern tube shaft match.

The section of the arc copper bar is trapezoidal, the thickness equal in width of the trapezoidal bottom and sector notch.

Two seamed edge rounded corners of the arc copper bar inner wall.

The arc copper bar is fixed on sector notch inner wall using rivet, is uniformly provided on the circumferential wall of the arc copper bar Several counterbores for receiving the rivet.

The bearing body is equipped with several flange holes for being installed with stern pipe.

The bearing body is equipped with positioning convex shoulder close to the end face of stern pipe side, and the positioning convex shoulder is matched with stern pipe grafting It closes.

The central angle of the sector notch is 165 ° ~ 175 °.

The utility model has the beneficial effects that：The arc copper bar of the utility model is directly contacted with stern tube shaft, due to arc copper Item has good self-lubricating property, therefore bearing body not only can play good positioning and supporting role to stern tube shaft, will not also Stern tube shaft is caused to wear, and its cost is also very low.

Description of the drawings

Fig. 1 is the structural schematic diagram of the utility model embodiment.

Fig. 2 is sectional view along A-A in the utility model embodiment.

Fig. 3 is enlarged drawing at B in the utility model embodiment.

Fig. 4 is the usage state diagram of the utility model embodiment.

Stern pipe 01, stern tube shaft 02, bearing body 1, sector notch 2, arc copper bar 3, rounded corner 4, rivet 5, counterbore 6, flange hole 7, convex shoulder 8 is positioned.

Specific implementation mode

The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.

Embodiment as shown in Figure 1 and Figure 2：Its shape of bearing body 1 is one and half flange plates, and the endoporus of half flange plate is to use It is inlayed and arc copper bar 3 in sector notch 2, its inner circumferential wall of support stern tube shaft 02.Arc copper bar 3 has good self lubricity Can, therefore stern tube shaft 02 will not be caused to wear during filling in stern tube shaft 02；The thickness of arc copper bar 3 takes 3mm or so, bearing body 1 is manufactured using common iron, therefore the overall cost of false bearings is relatively low.

Embodiment as shown in Figure 1 and Figure 2：Bolt hole on half flange plate is used to assemble with stern pipe 01, and is leaned on half flange plate The nearly positioning convex shoulder 8 on 01 1 side end face of stern pipe, for being plugged in stern pipe 01.I.e. positioning convex shoulder 8 for position, bolt For fastening, the two cooperates in hole, not only has higher precision, but also can guarantee good intensity, and assemble and also compare side Just.

Embodiment as shown in Figure 3：The section of arc copper bar 3 is trapezoidal, the thickness etc. of trapezoidal bottom and sector notch 2 It is wide；Two seamed edge rounded corners 4 of 3 inner wall of arc copper bar；Arc copper bar 3 is fixed on 2 inner wall of sector notch, arc using rivet 5 Several counterbores 6 for receiving rivet 5 are uniformly provided on the circumferential wall of copper bar 3.Above structure is arc copper bar 3 and bearing body 1 A kind of mode, following requirement can be met：（1）3 fixation of arc copper bar, even if arc copper bar 3 is under the drive of stern tube shaft 02 Generation slightly deviates, and is not in certain a part of hanging situation of arc copper bar 3；（2）The corner angle of arc copper bar 3 itself are avoided to damage Hinder stern tube shaft 02；（3）5 evagination of rivet is avoided to damage stern tube shaft 02.

Embodiment as shown in Figure 1：The central angle of sector notch 2 is 165 ° ~ 175 °, this structure is primarily to facilitate the dress of stern tube shaft 02 It is incorporated in sector notch 2.It is more by controlling 1 height dimension of bearing body but in practical operation（H in Fig. 1）Tolerance, That is H selects negative common difference to realize above-mentioned purpose.

Obviously, above-described embodiment of the utility model is merely to illustrate that the utility model example, and is not Restriction to the embodiment of the utility model.For those of ordinary skill in the art, on the basis of above description On can also make other various forms of variations or variation.There is no need and unable to give poor example to all embodiments. And these connotation changes and variations that derived from for belonging to the utility model still fall within the utility model Protection domain.
