Description
Technical field
This utility model is related to hydraulic loaded field, especially, is related to a kind of Thrust Bearing Test Rig hydraulic loading device.
Background technology
At present, Large-scale Thrust Bearings testing stand needs the loading force of stable and high thrust, therefore, the requirement to charger
Comparison is high.It is certain due to producing between bearing shell and runner plate when tested main pump bearing is loaded in conventional Thrust Bearing Test Rig design
Deformation, so as to produce axial gap, in this case charger just can not apply stable push away with accurate axial direction to main shaft
Power.Hydrostatic bearing cannot quickly flow out by main shaft side high temperature grease in prior art can cause hydrostatic bearing temperature too high,
So as to affect the performance of hydrostatic bearing.
The content of the invention
This utility model provides a kind of Thrust Bearing Test Rig hydraulic loading device, it is intended to compensate tested main pump shaft acknowledgement of consignment
The axial gap that produces during row and solve hydrostatic bearing flow into main shaft side high temperature grease cannot quickly flow out cause it is quiet
The problem of pressure Bearing Temperature.
For achieving the above object, embodiment of the present utility model is filled there is provided a kind of Thrust Bearing Test Rig hydraulic loaded
Put, including：Thrust disc, casing, the load cylinder in casing and slave cylinder, thrust disc is fixed with main shaft by flat key
Connection, load cylinder is bolted on casing, and slave cylinder can be enclosed within up or down in load cylinder, load cylinder
Closed loading oil pocket is cooperatively formed with slave cylinder, loading oil pocket is sealed by O-ring seal.
Further, slave cylinder bottom opens up annular oil cavity and cooperatively forms hydrostatic bearing with thrust disc.
Further, load cylinder passes through respectively load cylinder fuel feed hole with hydrostatic bearing fuel feed hole by two with hydrostatic bearing
The different oil pump feed of platform.
Further, pin is installed between slave cylinder and load cylinder, make slave cylinder can within the specific limits on move down
Move and can not circumferentially rotate.
Further, collection chamber is offered inside slave cylinder, collects the lubricating oil that hydrostatic bearing flows into main shaft side
Quickly flowed back in casing by spill port afterwards.

Specific embodiment
Fully to explain the technical solution of the utility model, it is described in detail below in conjunction with accompanying drawing.
Illustrate：The direction of arrow shown in Fig. 1 is the flow direction of hydraulic oil and lubricating oil.
As shown in figure 1, embodiment of the present utility model provides a kind of Thrust Bearing Test Rig hydraulic loading device, the dress
Put including：Casing（2）, installed in casing（2）Interior thrust disc（3）, load cylinder（5）And slave cylinder（4）, thrust disc（3）
With main shaft（1）It is fixedly connected by flat key, load cylinder（5）It is bolted on casing（2）On, slave cylinder（4）Can go up
Under be movably enclosed within load cylinder（5）It is interior, load cylinder（5）With slave cylinder（4）Cooperatively form closed loading oil pocket（8）,
Loading oil pocket（8）By O-ring seal（14）Sealing, slave cylinder（4）Bottom opens up annular oil cavity（13）With thrust disc（3）
Cooperatively form hydrostatic bearing（11）.
Load cylinder of the present utility model（5）With hydrostatic bearing（11）By two different oil pump feeds, load cylinder（5）
High pressure liquid press oil by load cylinder fuel feed hole（7）Stream enters to load oil pocket（8）, so that slave cylinder（4）To thrust disc（3）Produce
Raw axial thrust, hydrostatic bearing（11）Lubricating oil by hydrostatic bearing fuel feed hole（12）Stream enters annular oil cavity（13）, annular oil cavity
（13）In lubricating oil in slave cylinder（4）Bottom surface and thrust disc（3）Surface forms one layer of oil film.
In order to improve hydrostatic bearing（11）Radiating, in slave cylinder（4）Inside offers collection chamber（9）, hydrostatic bearing
（11）Main shaft is flowed into during operation（1）The high temperature grease of side comes together in collection chamber（9）Pass through spill port again（10）Flow rapidly into
Casing（2）In.
For the axial gap produced when compensating tested main pump shaft acknowledgement of consignment row, slave cylinder of the present utility model（4）Can be
Move up and down in certain limit.
When a kind of Thrust Bearing Test Rig hydraulic loading device of embodiment runs, hydrostatic bearing（11）In oil film pair
Slave cylinder（4）There is circumferential shearing force bottom surface, to prevent slave cylinder（4）Rotate under this shearing force, in slave cylinder（4）
With load cylinder（5）Between pin is installed（6）, pin（6）With slave cylinder（4）Perforate interference fit, with load cylinder（5）
Opening gaps coordinate so that slave cylinder（4）Can within the specific limits move up and down, but can not rotate.
