Description
Technical field
The utility model relates to a kind of boats and ships separation coupling, belongs to technical field of ships.
Background technique
Separable coupling is the critical piece for connecting stern tube shaft in screw shaft of ship.The separable coupling used at present mainly establishes a stern tube shaft pilot hole in shaft coupling one end, assembling hole wall is provided with a spline matched with stern tube shaft, be provided with for fixing stern tube shaft bolt hole at the other end, mainly there is following problem in this type of shaft coupling: 1. spline is arranged for radial, when transmission, also diametrically, torque force is little for the active force of moment of torsion; 2. and creep easy to wear at the lower spline that to run up for a long time, often need change shaft coupling, working life is short; 3. the bolt of fastening stern tube shaft easily loosens; In view of above-mentioned problems, be badly in need of a kind of high performance shaft coupling.
Model utility content
For solving the problem, the utility model proposes a kind of torque force, life-span long, the boats and ships separation coupling of bolt looseness can be prevented.
The technological scheme that the utility model adopts is: a kind of boats and ships separation coupling, comprise shaft coupling body, the right side of shaft coupling body has a flange disk, on flange disk, radial equipartition has multiple attachment hole, the left end of described shaft coupling body interior is provided with stern tube shaft attachment hole, the right-hand member of shaft coupling body interior is provided with bolt hole, and is interconnected between stern tube shaft attachment hole and bolt hole; On the sidewall of stern tube shaft attachment hole, radial equipartition has multiple radial spline, the uniform multiple axial splines of annular on the step wall inside stern tube shaft attachment hole; Described bolt hole is polygonal counterbore, and its inside is provided with associated bolt fixed cover.
Further, described radial spline and axial splines are equipped with four, and mutual alignment is crossbar architectures.
Further, described stern tube shaft attachment hole is cone shape hole, and its tapering mates with stern tube shaft tapering.
Further, described bolt fixed cover right flank also have two annulus.
Compared with prior art, it has following beneficial effect to the utility model:
Radial and axial in stern tube shaft attachment hole of boats and ships separation coupling of the present utility model is provided with multiple spline simultaneously, torsional interaction power can simultaneously from the radial and axial transmission of stern tube shaft, effectively increase torque force, when the wherein wearing and tearing of certain spline or creep, all the other splines also can continue normal use, without the need to changing shaft coupling immediately, improve working life, set bolt fixed cover can prevent bolt looseness effectively; It has the advantages such as rational in infrastructure, torque force, life-span length and usability are good.

Embodiment
A kind of boats and ships separation coupling as shown in Figure 1 to Figure 3, comprise shaft coupling body 1, the right side of shaft coupling body 1 has a flange disk 2, on flange disk 2, radial equipartition has multiple attachment hole 3, the left end of described shaft coupling body 1 inside is provided with stern tube shaft attachment hole 4, the right-hand member of shaft coupling body 1 inside is provided with bolt hole 5, and is interconnected between stern tube shaft attachment hole 4 and bolt hole 5; On the sidewall of stern tube shaft attachment hole 4, radial equipartition has multiple radial spline 6, the uniform multiple axial splines 7 of annular on the step wall inside stern tube shaft attachment hole 4, and stern tube shaft during installation also needs to arrange the keyway matched with radial spline 6 and axial splines 7; Described bolt hole 5 is polygonal counterbore, and its inside is provided with associated bolt fixed cover 8, needs first to take out this bolt fixed cover 8 before stern tube shaft is installed, again bolt fixed cover 8 is inserted in after stern tube shaft bolt fixes, bolt head can be fixed by firmly, loosens to prevent it.
Wherein, described radial spline 6 and axial splines 7 are equipped with four, and mutual alignment is crossbar architectures; Described stern tube shaft attachment hole 4 is cone shape hole, and its tapering mates with stern tube shaft tapering; Described bolt fixed cover 8 right flank also have two annulus 9, so that take out bolt fixed cover 8 during dismounting.
Radial and axial in stern tube shaft attachment hole of boats and ships separation coupling of the present utility model is provided with multiple spline simultaneously, torsional interaction power can simultaneously from the radial and axial transmission of stern tube shaft, effectively increase torque force, when the wherein wearing and tearing of certain spline or creep, all the other splines also can continue normal use, without the need to changing shaft coupling immediately, improve working life, set bolt fixed cover can prevent bolt looseness effectively; It has the advantages such as rational in infrastructure, torque force, life-span length and usability are good.
Embodiment recited above is described preferred implementation of the present utility model, not limits design of the present utility model and scope.Under the prerequisite not departing from the utility model design concept; the various modification that related domain ordinary person makes the technical solution of the utility model and improvement; protection domain of the present utility model all should be dropped into; the technology contents of the utility model request protection, all records in detail in the claims.
