Abstract
The utility model discloses a kind of tail shaft nuts locking device, tail shaft nuts locking device is made up of tailing axle, nut, locking plectane, bolt and locking bar, described nut socket is fixed on tail the tip of the axis, described locking plectane is arranged on the terminal surface of described tailing axle, the end of described tailing axle is provided with assembly department, and described locking plectane is provided with the hole relative with described assembly department.The superior effect of the utility model tail shaft nuts locking device is: locking plectane is bolted on the end of tailing axle, and the outer wall of nut is close in bending locking bar one end, and one end is welded on locking plectane.When nut location changes, first can slice off the weld seam between locking plectane and locking bar, weld again after the position of nut is fixing, thus can Reusability, and can installation quality be ensured.This practical tail shaft nuts locking device can reuse locking bar, avoids unnecessary human and material resources, financial resources to waste.
Description
Technical field
The utility model shipbuilding technical field, is specifically related to a kind of tail shaft nuts locking device.
Background technique
The locking of tail shaft nuts is one of key of the no reliably working of ship propulsive shafting performance.Be generally all that locking bar is bolted on axle head in the past, and the two ends of locking bar bend to nut direction, the limit of exchange premium hexagonal or octagon nut, or the groove being adjacent to round nut.But because the separation coupling of propeller cavitation or tailing axle adopts tapering to be connected with tailing axle, compress propeller cavitation or shaft coupling employing tail shaft nuts, assemble each time and all in identical position, thus the tightening degree of locking bar and nut can not be affected, in order to ensure installation quality, often need to change locking bar.
Model utility content
The utility model provides a kind of tail shaft nuts locking device, adopts tail shaft nuts, owing to assembling all at diverse location at every turn, affect the technological deficiency of the tightening degree of locking bar and nut with the compression propeller cavitation or shaft coupling that solve existing ship.
In order to solve above technical problem, the technological scheme that the utility model is taked is:
A kind of tail shaft nuts locking device, tail shaft nuts locking device is by tailing axle, nut, locking plectane, bolt and locking bar are formed, described nut socket is fixed on described tail the tip of the axis, described locking plectane is arranged on the terminal surface of described tailing axle, the end of described tailing axle is provided with assembly department, described locking plectane is provided with the hole relative with described assembly department, described bolt coordinates with described assembly department and hole, described locking bar is made up of the first steel plate and the second steel plate being mutually right angle, described first Plate Welding is on described locking plectane, described second steel plate is close on the outer wall of described nut.
Be preferably, described assembly department and hole respectively have two.
Be preferably, described two assembly departments are relative to the Central Symmetry of described tailing axle.
Be preferably, described two holes are relative to the Central Symmetry of described locking plectane.
Be preferably, described bolt has two, and described two bolt symmetries are fixed on described locking plectane.
After employing technique scheme, locking plectane is bolted on the end of tailing axle, and the outer wall of nut is close in bending locking bar one end, and one end is welded on locking plectane.When nut location changes, first can slice off the weld seam between locking plectane and locking bar, weld again after the position of nut is fixing, thus can Reusability, and can installation quality be ensured.This practical tail shaft nuts locking device can reuse locking bar, avoids unnecessary human and material resources, financial resources to waste.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the topology view of the utility model tail shaft nuts locking device;
Fig. 2 is the plan view of the utility model tail shaft nuts locking device.
Embodiment
For making the object of the utility model embodiment, technological scheme and advantage clearly, below in conjunction with the accompanying drawing in the utility model embodiment, technological scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1 to Figure 2, tail shaft nuts locking device is made up of tailing axle 1, nut 2, locking plectane 3, bolt 4 and locking bar 5.Nut 2 is fixed by socket the end at tailing axle 1, locking plectane 3 is arranged on the terminal surface of tailing axle 1, the end of tailing axle 1 is provided with assembly department, locking plectane 3 is provided with the hole relative with assembly department, and assembly department and hole respectively have two, two assembly departments are relative to the Central Symmetry of tailing axle 1, and two holes are relative to the Central Symmetry of locking plectane 3.Bolt 4 has two, and two bolts 4 pass the hole on locking plectane 3 thus are fixed on the assembly department of tailing axle 1 by locking plectane 3.Locking bar 5 is made up of the first steel plate 51 and the second steel plate 52 being mutually right angle, and the first steel plate 51 is welded on locking plectane 3, and the second steel plate 52 is close on the outer wall of nut 2.
Two bolts 4 are symmetricly set on locking plectane 3, thus locking plectane 3 is firmly fixed on tailing axle 1 by bolt 4, after the position of nut 2 is fixing, is welded on nut 2 by the second steel plate 52, thus can effectively prevents nut 2 from coming off from tailing axle 1.
Locking plectane 3 is fixed on the end of tailing axle 1 by bolt 4, the outer wall of nut 2 is close in bending locking bar 5 one end, and one end is welded on locking plectane 3.When nut 2 change in location, first can slice off the weld seam between locking plectane 3 and locking bar 5, weld again after the position of nut 2 is fixing, thus can Reusability, and can installation quality be ensured.This practical tail shaft nuts locking device can reuse locking bar 5, avoids unnecessary human and material resources, financial resources to waste.
Last it is noted that above embodiment only illustrates the technical solution of the utility model, be not intended to limit; Although be described in detail the utility model with reference to previous embodiment, those of ordinary skill in the art is to be understood that: it still can be modified to the technological scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of each embodiment's technological scheme of the utility model.
