Abstract
The utility model discloses a throttle type bearing lubricating oil path which comprises a shaft supported by a bearing and a housing on which the shaft is mounted, wherein two clearance fit surfaces for throttling are arranged on the shaft and the housing; an annular groove is formed between the two clearance fit surfaces and is communicated with lubricating oil; an oil hole is formed in the housing and is used for supplying oil to the annular groove; an axial hole is formed in the shaft and is used for conveying the lubricating oil to another end. According to the throttle type bearing lubricating oil path, the external pressure lubricating oil is distributed to two bearings at the same time by a throttling effect of a clearance on liquid; compared with a traditional spray lubrication mode, oil supply points are reduced and the supplied lubricating oil can be completely used for lubrication.
Description
Technical field
The utility model relates to the design of Machine Design middle (center) bearing lubricating oil path, belongs to mechanical field.
Background technique
The bearing of the key position in machinery often needs pressure lubrication, and spray is the most frequently used mode.Traditional spray mode is, at each lubricated target proximity, a nozzle is set, and this makes lubricant oil access point and nozzle quantity relatively many; In addition, the lubricant oil spraying also may some be splashed to other places, completely lubricating for target.
For the problems referred to above, throttle type bearing lubricating oil circuit is proposed, reduced lubricant oil access point and removed nozzle; And, the lubricant oil that the supplies target bearing of can all flowing through.
Summary of the invention
The purpose of this utility model is to provide throttle type bearing lubricating oil circuit, reduces lubricant oil access point, and makes more effectively lubricating for target bearing of supplied lubricant oil.
For achieving the above object, the utility model has adopted following technological scheme: throttle type bearing lubricating oil circuit, comprise by the axle of bearings and the housing of this axle is installed, on axle and housing, there are two sections in order to the Spielpassung face of throttling, between two intersegmental gap fitting surfaces, be provided with annular groove, housing is provided with oilhole in order to annular groove fuel feeding, and axle is provided with axial bore in order to lubricant oil is transferred to the other end.
The oilhole of pressure lubrication oil on housing enters annular groove, through the gap of annular groove both sides, directly flows through the bearing adjacent with annular groove in throttling Hou， mono-tunnel respectively; Axial bore in another road warp beam flows to another bearing.
The utility model has reduced oil-feeding points with lubricated the comparing of traditional with spraying, and oil-feeding points is lubricated two bearings simultaneously, and, institute's lubricant oil that supply can be completely lubricated for two bearings, lubricated front nothing is splashed.
Accompanying drawing explanation
Fig. 1 is the structure diagram of the utility model throttle type bearing lubricating oil circuit.
In figure: housing (1), bearing (2), axle (3), bearing (4).
Embodiment
Relevant detailed description of the present utility model and technology contents, coordinate accompanying drawing to be described as follows, yet accompanying drawing only provides the use of reference with explanation, is not used for the utility model to be limited.
Shown in Fig. 1, throttle type bearing lubricating oil circuit, comprises housing (1), bearing (2), bearing (4), axle (3).Axle (3) and bearing (2) and bearing (4) are installed in housing (1).
On housing (1) and axle (3), there are two intersegmental gap fitting surfaces, between two intersegmental gap fitting surfaces, are provided with annular groove and are located on axle (3).
There is axial hole at axle (3) center.
Housing (1) is provided with oilhole and is communicated with the annular groove on axle (3).
Pressure lubrication oil enters annular groove Hou， mono-tunnel on axle (3) after the gap throttling of groove right side from the oilhole on housing (1), all flows through bearing (4); Another road is after the gap throttling in annular groove left side, and the through hole at the axle of flowing through (3) center, then will all flow through bearing (2).In actual design, the opening on housing (1) right side will be sealed by the transmission part (such as motor) being connected with axle (3).
The utility model is specially adapted to support the pressure lubrication of two bearings of same axle.
The foregoing is only preferred embodiment of the present utility model, non-in order to limit the scope of the claims of the present utility model, other use the equivalence of patent spirit of the present utility model to change, and all should all belong to the scope of the claims of the present utility model.
Claims (3)
1. throttle type bearing lubricating oil circuit, is characterized in that, comprises one by the axle of bearings and the housing of this axle is installed; On described axle and housing, there are two sections in order to the Spielpassung face of throttling, between two intersegmental gap fitting surfaces, are provided with annular groove in order to connect lubricant oil.
2. throttle type bearing lubricating oil circuit according to claim 1, is characterized in that, described housing is provided with oilhole in order to the annular groove fuel feeding to described.
3. throttle type bearing lubricating oil circuit according to claim 1 and 2, is characterized in that, described axle is provided with axial bore in order to lubricant oil is transferred to the other end.
