Detailed description of the invention
Summary of the invention feature and effect for further appreciating that the present invention is hereby illustrated following example, and coordinates accompanying drawing detailed
It is described as follows, refers to Fig. 1, Fig. 2.
As shown in Figure 1 and Figure 2: the shaft of hydraulic motor 1 is connected with axle 3 by shaft coupling 2, shaft coupling 2 and axle 3
With bonded, the other end of axle 3 is fixed with impeller 4, and impeller 4 is fixed with axle 3 end by A pressing plate 5 and bolt, axle
The outside of 3 is fixed with A housing 6, and two bearings 7 are fixed at the two ends in A housing 6 respectively, and two bearings 7 are supported on A
In housing 6, and compressed by A, B bearing gland 8,8-1 respectively, ends A, B bearing gland 8,8-1 Yu A shell
All with zero RunddichtringO A 9 in the middle of body 6, between A, B bearing gland 8,8-1 and axle 3, it is respectively provided with zero RunddichtringO G 21,
With groove 10 on B bearing gland 8-1, B bearing gland 8-1 is fixed with floating sealing ring 12 by zero RunddichtringO B 11
Half, second half of floating sealing ring 12 is fixed on B pressing plate 14 by zero RunddichtringO C 13, described floating sealing ring 12
The contact surface of two halves is facet；Being fixed with zero RunddichtringO D 15 between B pressing plate 14 and axle, the side of B pressing plate 14 leads to
Crossing the plate 16 being inserted in axial trough to fix with axle 3, A housing 6 is welded together with B housing 17, B housing 17 and C shell
Body 18 is connected with by flange, and the centre of B housing 17 and C housing 18 is with zero RunddichtringO E 19, C housing
18 is middle with hydraulic motor 1 with zero RunddichtringO F 20, and C housing 18 is connected with by flange with hydraulic motor 1；
When axle 3 rotates, right bearing gland 8-1 because fixing with A housing 6, A housing 6 and B housing 17 and C housing 18
Fixing, therefore right bearing gland 8-1 is motionless, the zero RunddichtringO B 11 and the one of floating sealing ring 12 contacted with bearing gland 8-1
Half does not turns under the effect of frictional force, rotates under the drive of axle 3 in the B pressing plate 14 groove 10 on right bearing gland 8-1,
The zero RunddichtringO C 13 contacted with B pressing plate 14 and the half of floating sealing ring 12 under the effect of frictional force with B pressing plate 14
Rotating, the two halves phase mutual friction of floating sealing ring 12, axle 3 rotates impeller 4 and rotates.
During operation, connecting the underwater hydraulic motor 1 being fixed on ditcher, the shaft of hydraulic motor 1 passes through shaft coupling 2
Rotating together with axle 3, A housing 6, B housing 17 and C housing 18 are fixed together, and are fixed with two in A housing 6
Bearing 7, A, B two bearing glands 8,8-1 compress respectively, with groove 10 on B bearing gland 8-1, B bearing gland
The upper half being fixed with floating sealing ring 12 by zero RunddichtringO B 11 of 8-1, second half of floating sealing ring 12 is by zero RunddichtringO
C 13 is fixed on B pressing plate 14, and the contact surface of two halves floating sealing ring 12 is facet；Its pressing plate 14 under the drive of axle 3
Rotating in groove 10 on B bearing gland 8-1, the two halves phase mutual friction of floating sealing ring 12, axle 3 rotates impeller 4 and revolves
Turn；Because adding multiple zero RunddichtringO at key position, the possibility that seawater enters underwater hydraulic motor 1 and axle 3 is minimum.
Advantage is: sealing simple in construction, easy for installation, good sealing effect, frictional resistance is little, and service life is long.Reduce
The maintenance of hydraulic motor and turnover rate, improve operating efficiency, reduce cost.
Embodiment described above is only to be described the preferred embodiment of the present invention, not to the scope of the present invention
Being defined, on the premise of designing spirit without departing from the present invention, those of ordinary skill in the art are to technical scheme
The various deformation made and improvement, all should fall in the protection domain that claims of the present invention determines.
