Embodiment
Hereby to illustrate following examples for summary of the invention Characteristic of the present utility model can be understood further, and coordinate accompanying drawing to be described in detail as follows, refer to Fig. 1-Fig. 3.
As shown in Fig. 1-Fig. 3: the shaft of oil hydraulic motor 1 is connected with axle 3 by coupling 2, coupling 2 is connected with key with axle 3, the other end of axle 3 is fixed with impeller 4, impeller 4 is by pressing plate A5 and bolt and axle 3 end winding support, the outside of axle 3 is fixed with housing A6, two bearings 7 are fixed at two ends in housing A6 respectively, two bearings 7 are supported in housing A6, and respectively by bearing gland A, B 8 and 8-1 compresses, bearings at both ends gland A, all with zero RunddichtringO A9 in the middle of B 8 and 8-1 and housing A6, bearing gland A, respectively with zero RunddichtringO G21 between B 8 and 8-1 and axle 3, with groove 10 on bearing gland B 8-1, bearing gland B 8-1 is fixed with the half of floating sealing ring 12 by zero RunddichtringO B 11, second half of floating sealing ring 12 is fixed on pressing plate B 14 by zero RunddichtringO C 13, the surface of contact of described two halves floating sealing ring 12 is facet, zero RunddichtringO D 15 is fixed with between pressing plate B 14 and axle, the side of pressing plate B 14 is fixed with axle 3 by the plate 16 be inserted in axial trough, housing A 6 and housing B 17 are welded together, housing B17 is connected middle with zero RunddichtringO E 19 with housing C 18 by flange with bolt, housing C 18 is middle with zero RunddichtringO F 20 with oil hydraulic motor 1, and housing C 18 is connected by flange bolt with oil hydraulic motor 1, when axle 3 rotates, bearing gland B 8-1 is because fixing with housing A 6, housing A 6 fixes with housing B 17 and housing C 18, therefore bearing gland B 8-1 is motionless, the zero RunddichtringO B 11 contacted with bearing gland B 8-1 and the half of floating sealing ring 12 do not turn under the effect of frictional force, rotate in groove 10 on bearing gland B 8-1 of the drive press table B 14 of axle 3, the zero RunddichtringO C 13 contacted with pressing plate B14 and the half of floating sealing ring 12 are rotated with pressing plate B14 under the effect of frictional force, the two halves phase mutual friction of floating sealing ring 12, axle 3 rotates impeller 4 and rotates.
During operation, connect the underwater hydraulic motor 1 be fixed on trenching machine, the shaft of oil hydraulic motor 1 is rotated together with axle 3 by coupling 2, housing A6, housing B17 and housing C18 are fixed together, housing A6 internal fixtion has two bearings 7, two bearing gland A, B 8 and 8-1 compress respectively, with groove 10 on bearing gland B 8-1, bearing gland B 8-1 is fixed with the half of floating sealing ring 12 by zero RunddichtringO B11, second half of floating sealing ring 12 is fixed on pressing plate B 14 by zero RunddichtringO C13, and the surface of contact of two halves floating sealing ring 12 is facet; Rotate in groove 10 on bearing gland B 8-1 of the drive press table B 14 of axle 3, the two halves phase mutual friction of floating sealing ring 12, axle 3 rotates impeller 4 and rotates; Because adding multiple zero RunddichtringO at key position, the possibility that seawater enters underwater hydraulic motor 1 and axle 3 is minimum.
