Description
Technical field
The utility model is related to oil seal technique field, more particularly to a kind of installation knot of hydraulic oil pump rotary shaft oil sealing
Structure.
Background technology
Currently, the rotary shaft of hydraulic oil pump available on the market is with oil sealing characteristic：On the inside of oil pump, by shell
Internal side and bearing are clipped in the middle, and can effectively prevent hydraulic fluid leak, have many advantages, such as that applied widely, antifouling property is good；
Its deficiency is：Installation dimension has an impact axis and bearing size, and oil sealing is hidden in inside, it is difficult to find its behaviour in service, also not
It is easily installed and replaces, and there are certain difficulty of processing for seal mounting hole and bearing mounting hole.
Invention content
The purpose of this utility model is that it is in view of the drawbacks of the prior art and insufficient, a kind of hydraulic oil pump rotary shaft use is provided
The mounting structure of oil sealing, oil sealing are fixed with the bulge loop of circlip for hole A and oil pump case inner edge, can be from the outer of oil pump case
Oil sealing working condition is intuitively seen in side, and oil sealing and bearing are installed separately, and is not only convenient for design processing oil sealing installation
Hole and bearing mounting hole size are also convenient for installing and examine.
To achieve the above object, the utility model uses following technical scheme.
A kind of mounting structure of hydraulic oil pump rotary shaft oil sealing described in the utility model, including oil pump case and be set to
Pump shaft in oil pump case is additionally provided with internal circlip B, the axis being sheathed on successively from left to right on pump shaft in oil pump case
Hold, oil sealing and internal circlip A, the inner circumferential of oil pump case is equipped with bulge loop, bearing axially support be set to internal circlip B with it is convex
Between ring, oil sealing is axially supported and is set between bulge loop and internal circlip A.
Further, it is provided with axle elastic spring between internal circlip B and pump shaft.
Further, internal circlip B, bearing, oil sealing and internal circlip A are radially located in pump shaft and oil pump
Between shell.
Further, pump shaft is equipped with step, the outer ring of bearing be connected to internal circlip B, oil pump case inner wall and
Between bulge loop, the inner ring of bearing is connected between internal circlip B, pump shaft outer wall and step.
Further, bearing is rolling bearing.
The utility model has the beneficial effect that：Oil sealing circlip for hole A and oil pump case inner edge in the utility model
Bulge loop is fixed, and oil sealing working condition can be intuitively seen from the outside of oil pump case, and oil sealing and bearing are to be installed separately
, it is not only convenient for design processing seal mounting hole and bearing mounting hole size, is also convenient for installing and examine.The utility model structure
Setting is reasonable, easy for installation, can observe the working condition of oil sealing in real time.
