Abstract
A kind of axle system flange pilot hole align structures, 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.
Description
Technical field
This utility model relates to marine shafting flange bolt hole align structures.
Background technology
In the boats and ships of conventional tail type, for the Propulsion Systems formed by jackshaft, propeller shaft and main frame flywheel,
Flange opening (GAP) in shaft and skew (SAG) adjust after examination terminates, need by above three parts assembly connection be
Integrally, by adjusting the height of the temporary support below jackshaft, thus regulate the longitudinally height of jackshaft, pass through dish subsequently
Dynamic main frame flywheel or propeller shaft, make the dress on the flange of the pilot hole on the flange of main frame flywheel end or propeller shaft end
Distribution turns to be directed at the pilot hole on jackshaft corresponding end flange, and copper alignment pin inserts after alignment the assembling of two alignments
In hole, make jackshaft be fixed with one with propeller shaft with main frame flywheel and jackshaft in an interference fit, due in
Countershaft and main frame flywheel and jackshaft are to be connected by interference fit with propeller shaft, and therefore, the required precision to pilot hole is non-
Chang Gao, once pilot hole precision does not reaches standard, then, during causing assembling, alignment pin inserts the end face of end and withstands on jackshaft
On end face of flange on, on the end face of main frame flywheel flange or on the end face of propeller shaft flange, constantly tapping location
During pin, cause alignment pin end face and end face of flange to clash into, cause alignment pin damage and cause the flange on main frame flywheel, in
Flange on countershaft or the flange on propeller shaft damage, and cause and need to change parts, and again make alignment pin, cause
Cost drastically raises；For solving the problems referred to above, need to be by manually not stopping the flange on adjustment jackshaft and corresponding main frame flywheel
The Aligning degree of the pilot hole on flange and propeller shaft flange, takes time and effort；Further, since alignment pin outside dimension must be root
Closing according to matching size after pilot hole polish, therefore, this kind of speciality alignment pin cannot recycle, and therefore, causes each sleeve
System needs one group of specific assembly tool, causes cost significantly to raise.
Utility model content
This utility model aim to provide a kind of can alignment flange pilot hole quick, accurate and the axle system flange of reusable edible
Pilot hole align structures, it is provided that assembly work efficiency, time saving and energy saving, reduce manufacturing cost.
A kind of axle system described in the utility model flange pilot hole align structures, including the copper inserted in two flange pilot holes
Matter tapered sleeve and the cone rod matched with tapered sleeve, described tapered sleeve is column, and tapered sleeve outer surface diameter is less than flange pilot hole aperture, cone
Set inner surface is conical through-hole, and described cone rod is tapered, cone rod major diameter one end by the conical through-hole within tapered sleeve little directly
One end, footpath is inserted, and the end face of described cone rod minor diameter one end is provided with rotating rod.
A kind of axle system described in the utility model flange pilot hole align structures, by copper tapered sleeve and excellent the coordinating of cone,
Realizing the pilot hole alignment on two flanges connected, owing to tapered sleeve uses copper material, therefore, plasticity is good, can be by cone rod and cone
The interference fit of set is installed, and makes tapered sleeve radially extend out, so that two flanges can relatively rotate, forces flange pilot hole to be directed at, by
In tapered sleeve external diameter less than flange pilot hole aperture, therefore, can easily tapered sleeve be inserted in the pilot hole that two flanges are corresponding, it is to avoid former
Have in 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 flange end
On face, to damage alignment pin and flange；Owing to being made the flange pilot hole pair of adjacent connection by the tensioner mode of tapered sleeve with cone rod
Standard, 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 is adopted
With 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, and further significantly reduces manufacturing cost, and owing to tapered sleeve takes through-hole structure, because of
This, make tapered sleeve material few, and cost is lower.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation
Fig. 2 is Fig. 1 part A partial enlarged drawing.
Detailed description of the invention
A kind of axle system flange pilot hole align structures, as depicted in figs. 1 and 2, including the copper inserted in two flange 1 pilot holes
Matter tapered sleeve 2 and the cone rod 3 matched with tapered sleeve 2, described tapered sleeve 2 is in column, and tapered sleeve 2 outer surface diameter is less than flange 1 pilot hole
Aperture, tapered sleeve 2 inner surface is conical through-hole, and described cone rod 3 is tapered, bores one end of excellent 3 major diameters by the taper within tapered sleeve 2
Minor diameter one end of through hole is inserted, and the end face of the excellent 3 minor diameter one end of described cone is provided with rotating rod 4.
The range of taper of the conical through-hole of described tapered sleeve 2 is 1:15 ~ 1:25, such as 1:15,1:18,1:20,1:22,1:25
Deng, preferably 1:20；Range of taper 1:15 ~ the 1:25 of described cone rod 3, such as 1:15,1:18,1:20,1:22,1:25 etc., preferably 1:
20.Under this tapering, the alignment of the flange pilot hole that this align structures is widely used in marine shafting can be made, improve alignment knot
The cyclic utilization rate of structure, reduces manufacturing cost.
Described rotating rod 4 is threaded bar, and nut 5 is tightened in threaded bar, by arranging nut 5, it is simple to manually rotate rotation
Transfer rod 4, simple to operate, time saving and energy saving, meanwhile, by arranging nut 5, it is also possible to make the flange of two connections be fastened as a whole, keep away
Exempt from boats and ships in running, produce vibration, and make align structures loosen, make the flange 1 of two connections depart from.
Described tapered sleeve 2 length thickness sum less than two flanges 1 and the thickness more than single flange 1, described threaded bar
On nut 5 and tapered sleeve 2 end face between threaded bar on be arranged with copper stop washer 6, described stop washer 6 is in T shape, logical
Crossing tightening nut 5, major diameter one end end face of stop washer 6 pushes against in flange 1 surface, and minor diameter one end of stop washer 6 is stretched
Entering in flange 1 pilot hole, its end face pushes against in tapered sleeve 2 end face, thus flange 1 of avoiding wearing and tearing in nut 5 rotation process, the most also
Tapered sleeve 2 is avoided to move axially.
Excellent 3 materials of described cone are steel, owing to cone rod 3 can bear certain puller system extruding force during assembling, because of
This, the cone rod 3 made by steel, its intensity is high, and stress is good.
