Description
Technical field
The utility model relates to thrust oil tray technical field, particularly relates to a kind of thrust oil tray structure of oil mist prevention.
Background technique
Unit is in high speed operation, the quiet oil of the viscous driven in thrust bearing oil sump moves by the outer wall of thrust collar runner plate, pasta is made to gush height or splashing to oil groove outer wall because of centrifugal action, oil simultaneously in oil groove is also formed and rotates torrent motion, but the oil of motion is subject to runner plate four joint hinge holes stops and agitaion causes pasta to be filled with and torrent.Moreover, in unit running process, along with oil temperature height, oil in thrust bearing oil sump and volume of air expand, under the air pressure imbalance of space inside thrust collar and between gear oil pipe on pasta in external pressure and oil groove, easily cause local negative pressure, the change of thrust bearing oil sump internal cause pressure and the motion of rotation torrent, the factors such as temperature cause the inner epicoele of oil groove to there is the mist of oil of gaseous state.
Therefore, a kind of thrust oil tray structure of oil mist prevention is needed badly.
Model utility content
The purpose of this utility model is to provide a kind of thrust oil tray structure of oil mist prevention.
To achieve these goals, the technological scheme that the utility model provides is: the thrust oil tray structure providing a kind of oil mist prevention, comprise: main shaft, thrust collar, runner plate, support device, oil blocking barrel, described thrust collar upper end is fixedly connected with described main shaft, lower end is connected with described runner plate upper surface, and form annular space between described thrust collar lower end and described main shaft, described oil blocking barrel is sheathed on described spindle outer wall place, and be positioned at described annular space, and be reserved with space between described oil blocking barrel and described spindle outer wall, described runner plate lower surface is carried on described support device, seal ring is provided with between described oil blocking barrel outer wall and described thrust collar inwall, described seal ring is fixed on described spindle outer wall, and the fixed block described main shaft is also provided with for supporting described seal ring, run through described thrust collar outer wall and described annular space is also provided with at least twice balancing orifice, also flinger ring is provided with below described fixed block, described flinger ring outer wall and described 8 ~ 10 millimeters, thrust collar inwall interval.
Also comprise rotor field spider, oil tray shell and oil tray protecgulum, described rotor field spider, oil tray shell and oil tray protecgulum form holding space jointly, and are also provided with cooler in described holding space.
Described thrust collar upper end and described main shaft are integrative-structure.
Described thrust collar lower end and described runner plate integrative-structure.
Described thrust collar upper end and described main shaft are integrative-structure, and described thrust collar lower end and described runner plate integrative-structure.
Compared with prior art, due in the thrust oil tray structure of the utility model oil mist prevention, be provided with seal ring between described oil blocking barrel outer wall and described thrust collar inwall, described seal ring is fixed on described spindle outer wall, and described main shaft is also provided with the fixed block for supporting described seal ring.Therefore, can effectively prevent mist of oil from entering slip ring room along the gap between described oil blocking barrel and described thrust collar.
By following description also by reference to the accompanying drawings, the utility model will become more clear, and these accompanying drawings are for explaining embodiment of the present utility model.
Accompanying drawing explanation
Fig. 1 is the cross-sectional view of an embodiment of the thrust oil tray structure of the utility model oil mist prevention.
Embodiment
