Realize the driving to two pump impellers 1 via the live axle 6 correspondingly carrying two pump impellers 1, wherein, on output shaft 5 or on turbine 2, also can be provided with the relative support portion of the pump impeller 1 towards output shaft 5.
Two pump impellers 1 are surrounded by actionless housing 7 together with pump impeller shell 4 with turbine 2.Housing 7 has working medium inlet 8, and working medium is incorporated into fluid coupling via the working medium circulation loop 9 especially with storage container 10 of this working medium inlet from outside.In the embodiment shown, working medium directs in active chamber 3 via the nozzle 12 radially or along the extension of footpath axial direction after its percolation crosses rotation through-Penetration portion 11.
Live axle 6 is bearing in housing 7 via the first rolling bearing 13 and the second rolling bearing 14.As shown, the first rolling bearing 13 and the second rolling bearing Phase Proportion are as can be size determined much larger, and that is, this first rolling bearing has relatively large rolling element and larger-diameter bearing outer ring.First rolling bearing 13 is embodied as rigid bearing, and that is, it not only absorbs radial force but also ta-king up axial forces, and thus, live axle 6 remains in the position of the expectation of housing 7 inside.Second rolling bearing 14 is embodied as floating bearing, and that is, it can not ta-king up axial forces.
Output shaft 5 is located by the first rolling bearing 15 and the second rolling bearing 16 in housing 7.For live axle 6 two rolling bearings 13,14 described by content be also applicable to this two rolling bearings 15,16.
Each rolling bearing 13,14,15,16 has bearing inner race 17 and bearing outer ring 18.Bearing inner race 17 is positioned on live axle 6 or output shaft 5, and bearing outer ring 18 is positioned in housing 7.Be used for the bearing inner race 17 of supporting driving shaft 6 via live axle 6 is connected on the tensioning mutually of middle sleeve pipe 19, and therefore remain in their axial positions relative to each other.Be used for supporting the bearing inner race 17 of output shaft 5 by sleeve pipe 19 tensioning each other on output shaft 5, and therefore remain in their axial position on output shaft 5.Additionally, the side deviating from corresponding first rolling bearing 13,15 of corresponding second rolling bearing 14,16 is provided with inner sleeve 20, and corresponding bearing inner race 17 is relative to this inner sleeve 20 tensioning.
Inner sleeve 20 forms a part for shaft seal 21 simultaneously, and the inner chamber of fluid coupling in other words live axle 6 seals by the relative housing 7 of this shaft seal with output shaft 5.In the embodiment shown, inner sleeve forms the acting surface of the seal ring 22 being used for shaft seal 21.
Two shaft seals 21 are provided with so-called load shedding portion, this load shedding portion is connected with breather line 23, the working medium arriving shaft seal 21 inside exports from fluid coupling targetedly via this breather line.Breather line 23 extends in housing 7 inside.Corresponding to these breather line 23, shaft seal 24 is provided with breather line 25, makes live axle 6 or output shaft 5 in the first rolling bearing 13 and 15 outside relative housing seals by these shaft seals 24.
Second rolling bearing 14 with 16 bearing outer ring 18 respectively via one or more spring elements 26 relative housing 7 pretension.Correspondingly, in housing 7, be provided with breach or the axial bore of annular.On the side deviating from spring element 26, bearing outer ring 18 can be kept by the outer ring 27 of corresponding shaft seal 21.This outer ring 27 especially can be screwed on housing 7.
Now when the diagram with reference to the bearing in Fig. 1, illustrate in fig. 2 and how safeguard the first rolling bearing 13,15 and second rolling bearing 14,16 by lubricating fitting 28 again, its mode is: change with advantageously regular interval the grease being arranged in bearing 13 to 16.For this reason, in the region of each axial end portion of fluid coupling, respectively grease input part 29 is set for the first rolling bearing 13,15, and respectively grease input part 30 is set for the second rolling bearing 14,16.In addition, respectively common grease carry-out part 31 is set for the first rolling bearing 13,15 and second rolling bearing 14,16, that is, in the region of each axial end portion of fluid coupling, grease carry-out part 31 is set respectively for the rolling bearing 13 and 14 or 15 and 16 being separately positioned on there.
In the embodiment shown, each rolling bearing 13 to 16 is provided with two grease input parts 29.1 and 29.2 in other words 30.1 and 30.2, and this is not enforceable.But this tool has the following advantages, that is, two openings 32 of locating with peripherally offseting one from another can be provided with for each grease input part 29,30, grease input part 29,30 via these openings 32 at bearing 13 to 16 split shed.Therefore, advantageously can realize new grease better to distribute on the periphery of corresponding bearing 13 to 16.In addition, in the illustrated embodiment, for this reason also see Fig. 3, all rolling bearings 13 to 16 separately lubricate from fluid coupling both sides with new grease, and this is favourable, because be not to guarantee entering from both sides.
The opening of grease input part 29,30 on housing 7 outside marks with 33, and the opening of grease carry-out part 31 on housing 7 outside marks with 34.The opening of grease carry-out part 31 on bearing marks with 40.
On the opening 33 and 34 be positioned on housing 7, flexible pipe 35 is connected with respectively, the flange 36 of the corresponding bearing 13 to 16 (for this reason also see Fig. 1) of encirclement of this flexible pipe cross-over connection side and the free space had on housing 7 outside between opening 33 and the region of 34 for grease input part 29, grease input part 30 and grease carry-out part 31.In the embodiment shown, flexible pipe 35 is connected to housing 7 via the valve for forming opening 33 and 34 respectively.
The passage 37 of flange 36 inside shown in Figure 4, these passages form the decline of the decline of the grease input part 29.1 and 29.2 leading to the first rolling bearing 15 and the grease input part 30.1 and 30.2 towards the second rolling bearing 16.These passages 37 at corresponding rolling bearing 15,16 split shed, and are connected on the flexible pipe 35 shown in Fig. 2 and Fig. 3 at opposite side.In the embodiment shown, passage 37 is introduced by the hole in the flange 36 of housing 7, and seals with blind bolt or other closure members on outer end.Joint for flexible pipe 35 defines unique free entry port.
Corresponding passage 38 for common grease carry-out part 31 shown in Figure 5, this passage extends in flange 36 inside.In addition, breather line 23 is again seen.
In the hose coupling for passage 38, such as, can be provided with safety check 39, to avoid the less desirable spilling of grease.Additional or as an alternative, also can at grease carry-out part 31 or grease input part 29,30 outside opening on housing 7 region in this safety check is set.Refer again to Fig. 3, be the outer end of flexible pipe 35 for this reason there.
