Abstract

The invention discloses a shaft flange assembly hole alignment structure and an alignment method thereof. The assembly hole alignment of two connected flanges is realized through matching between a copper taper sleeve and a taper rod; as the taper sleeve adopts a copper material, the plasticity is good; the taper sleeve outwards expands in the radial direction through interference fit installation of the taper rod and the taper sleeve, so that the two flanges can relatively rotate to force alignment of assembly holes of the flanges; as the outer diameter of the taper sleeve is smaller than the aperture of the assembly holes of the flanges, the taper sleeve can be easily inserted in the corresponding assembly holes of the flanges to prevent damage of dowel pins and the flanges caused by direct collision of insertion ends of the copper dowel pins on the end surfaces of the flanges due to no alignment of the assembly holes of the two flanges in a traditional installation structure; and as the assembly holes of the adjacently connected flanges are aligned through an expansion mode of the taper sleeve and the taper rod, the assembly time and labors are saved, the working efficiency is high, and the precise alignment is realized through repeated adjustment without needing manual operations.

Description

A kind of axle system flange pilot hole align structures and alignment methods
Technical field
The present invention relates to marine shafting flange bolt hole align structures and alignment methods.
Background technology
nullIn the boats and ships of conventional tail type,For by jackshaft、The Propulsion Systems that propeller shaft and main frame flywheel are formed,Flange opening (GAP) in shaft and skew (SAG) adjust after examination terminates,Need to be integrated above three parts assembly connection,By adjusting the height of the temporary support below jackshaft,Thus regulate the longitudinally height of jackshaft,Main frame flywheel or propeller shaft is moved subsequently by dish,Make the pilot hole on the flange of the pilot hole on the flange of main frame flywheel end or propeller shaft end turn to the pilot hole on jackshaft corresponding end flange to be directed at,After alignment, copper alignment pin is inserted in the pilot hole of two alignments,Jackshaft is made to be fixed with one with propeller shaft with main frame flywheel and jackshaft in an interference fit,Owing to jackshaft and main frame flywheel and jackshaft are to be connected by interference fit with propeller shaft,Therefore,Required precision to pilot hole is the highest,Once pilot hole precision does not reaches standard,During then causing assembling,Alignment pin inserts the end face of end and withstands on the end face of flange on jackshaft、On the end face of main frame flywheel flange or on the end face of propeller shaft flange,During constantly tapping alignment pin,Alignment pin end face is caused to clash into end face of flange,Cause alignment pin damage and cause the flange on main frame flywheel、Flange on jackshaft or the flange on propeller shaft damage,Cause and need to change parts,And again make alignment pin,Cost is caused drastically to raise;For solving the problems referred to above, need to take time and effort by manually not stopping the flange on adjustment jackshaft and the Aligning degree of the pilot hole on corresponding main frame flywheel flange and propeller shaft flange;Further, since alignment pin outside dimension must be to close according to matching size after pilot hole polish, therefore, this kind of speciality alignment pin cannot recycle, and therefore, causes each sleeve system to need one group of specific assembly tool, causes cost significantly to raise.
Summary of the invention
It is desirable to provide a kind of can alignment flange pilot hole quick, accurate and the axle system flange pilot hole align structures of reusable edible and alignment methods, it is provided that assembly work efficiency, time saving and energy saving, reduce manufacturing cost.
A kind of axle system of the present invention flange pilot hole align structures, including the copper tapered sleeve inserted in two flange pilot holes and the cone rod matched with tapered sleeve, described tapered sleeve is column, tapered sleeve outer surface diameter is less than flange pilot hole aperture, tapered sleeve inner surface is conical through-hole, described cone rod is tapered, and one end of cone rod major diameter is inserted by minor diameter one end of the conical through-hole within tapered sleeve, and the end face of described cone rod minor diameter one end is provided with rotating rod.
A kind of axle system of the present invention flange pilot hole alignment methods, its step is as follows:
1) manual adjustment, makes main frame flywheel flange somewhat be directed at jackshaft corresponding end flange with jackshaft corresponding end flange and propeller shaft flange;
2) copper tapered sleeve is inserted in the pilot hole that adjacent two flanges are corresponding;
3) cone rod major diameter one end is inserted from the conical through-hole minor diameter one end within tapered sleeve;
4) artificial turn rotating rod, makes the conical through-hole surface laminating of cone rod outer surface and tapered sleeve;
5) manually rotate one group of rotating rod of homonymy simultaneously, cone rod is made to axially move relative to the conical through-hole of tapered sleeve, cone rod radially swell tapered sleeve, make tapered sleeve outer surface push against on the inner surface of flange pilot hole, make two flange relative movements of connection, thus the pilot hole on two flanges is directed at.
A kind of axle system flange pilot hole align structures of the present invention and alignment methods thereof, by copper tapered sleeve and excellent the coordinating of cone, realize the pilot hole alignment on two flanges connected, owing to tapered sleeve uses copper material, therefore, plasticity is good, can be installed by the interference fit of cone rod with tapered sleeve, tapered sleeve is made radially to extend out, so that two flanges can relatively rotate, flange pilot hole is forced to be directed at, owing to tapered sleeve external diameter is less than flange pilot hole aperture, therefore, can easily tapered sleeve be inserted in the pilot hole that two flanges are corresponding, avoid in original mounting structure, because the pilot hole of two flanges is not aligned with, and make the insertion end of copper alignment pin directly impinge upon on end face of flange, to damage alignment pin and flange;Owing to making the flange pilot hole of adjacent connection be directed at by the tensioner mode of tapered sleeve with cone rod, therefore, it is time saving and energy saving to assemble, and work efficiency is high, it is not necessary to manually realize precisely being directed at by repeatedly regulating;Owing to tapered sleeve uses copper material, its plasticity is good, therefore, in the case of tapered sleeve is without damaging, for the axle system flange that the aperture of flange pilot hole is close, this align structures can be recycled, further significantly reduce manufacturing cost, and owing to tapered sleeve takes through-hole structure, therefore, making tapered sleeve material few, cost is lower.
Accompanying drawing explanation
