In addition, pressure release passage can pass through drive shaft, the discharge channel is by the subsequent discharge space of working space and works
Entrance space in front of space is connected, wherein there are two the channel sections radially extended for the channel tool.Particularly, channel part
The exit opening of section can be set in the bolt head of centre bolt or be arranged between bolt head and supporting-point.
Detailed description of the invention
According to other features of the retarder of the utility model and other advantages of the utility model by referring to the drawings
Description of preferred embodiments obtains.
The utility model will be explained in further detail with reference to the accompanying drawings.The section of retarder is shown in FIG. 1.
Specific embodiment
Main structure is identical as the structure of the retarder according to the prior art herein.Therefore, the shell of retarder is by turning
Sub- shell 4 and 9 two parts of stator case composition.Stator 3 and bearing cage 21 are inserted into stator case 9.
Drive shaft 5 is supported in rotor case 4 via bearing 7, and is supported via bearing 8, bearing cage 21 and stator 2
In stator case 9.It is driven via driving wheel 23, which is engaged in the speed changer of automobile.It can be with from Fig. 1
It can be clearly seen, have to comply with certain sequence during assembly to realize assembling.In order to realize the structure, 5 more than one piece of drive shaft
It constructs likes, is made of main shaft part 10, bearing block 12 and centre bolt 14.
Two bearings 7,8 are tapered roller bearings, and the tapered roller bearing is clamped against one another in the mounted state or positions
At there is no axial gaps.
In order to assemble, two units are assembled and measured in the first step.In this case, first unit consists essentially of
Rotor case 4, rotor 1, main shaft portion 10 and the bearing 7 and driving wheel being arranged between rotor case 4 and main shaft portion 10
23。
Second unit includes bearing cage 21, stator 2 and bearing block, and the bearing block, which has, is arranged in bearing cage 21 and bearing
Bearing 8 between seat 12.
It is finished if these units are assembled, they is measured, for determining the thickness of required intermediate ring 22
Degree.Therefore can by simple mode in the case where considering manufacturing tolerance, determine bearing clearance or the bearing of bearing 7,8
Pretightning force.
Rotor assembly, which assembles from the two units and passes through centre bolt 14, to be tightened, wherein intermediate ring 22 determines axis
The distance between hold.
Next rotor unit is embedded in stator case 3.In this configuration, center can easily be shifted by pumping 20 pump impeller
On the supporting-point 19 of bolt 14.Alternatively, pump can be already installed in stator case 3, and the supporting-point on bolt head 18
6 are inserted into pump impeller.
Assembly can obviously be simplified by saving the middleware used in the past.Pass through the pressure release passage 15 of drive shaft 5 now
The subsequent pressure releasing chamber 16 of working space 3 and the entrance space 17 of 3 front of working space are connected directly, wherein the channel has
There are two the channel sections 15.1,15.2 radially extended.
