Technical field
The utility model relates to a kind of oil leakage preventing apparatus, particularly prevents the linkage structure of the planet wheel shaft of bulldozer transmission device leakage of oil.
Background technique
Present employed bulldozer is put the driving wheel height and the same central transmission of driving wheel, steering clutch, brake coupling and whole transmission is placed on the same axis.Crawler belt is around driving wheel and two front and back guide wheel shapes triangular in shape, the triangle crawler belt that namely is commonly called as.As shown in Figure 1, the transmission device of this bulldozer comprises bearing support 1, be socketed in the planet wheel shaft 2 in the bearing support 1, bearing 3, be socketed in planet wheel 4 and fixed plate 5 outside the bearing 3, planet wheel shaft 2 is comprised of upper tip 21 and lower axostylus axostyle 22, and upper tip 21 external diameters are greater than the external diameter of lower axostylus axostyle 22, upper tip 21 socket-connects with the upper end of bearing support 1, the upper end of lower axostylus axostyle 22 and bearing 3 socket-connect, the lower end of the lower end of lower axostylus axostyle 22 and bearing support 1 socket-connects, lower axostylus axostyle 22 middle parts of planet wheel shaft 2 also are provided with an O RunddichtringO 6, and this O RunddichtringO 6 is positioned at the lower end of bearing 3; Fixed plate 5 places bearing support 1 bottom, and is fixedly connected with by bolt 8 with lower axostylus axostyle 22.But the phenomenon of leakage of oil will appear in this bulldozer in use for some time, oil is to ooze out between the slit of planet axis bearing, and axle and bearing saddle bore have in relative rotation trend at work, this needs with regard to having caused planet axis and bearing saddle bore heavy wear to change, and has brought unnecessary trouble and greatly waste to the user.One O RunddichtringO is housed at the intermediate journal place of planet axis guarantees herein circumferential seal, because the O RunddichtringO is between planet axis and the bearing saddle bore, therefore also serious wear needs often to change.But in actual use, although repeatedly change O RunddichtringO herein, the not long leakage of oil of losing efficacy again of time.Simultaneously, because planet axis is outer little interior large Step Shaft, change herein the whole transmission of must disintegrating of O RunddichtringO, planet axis is extracted out in the other direction from leakage of oil, could change this O RunddichtringO, workload is large and effect is bad.
The model utility content
The purpose of this utility model is the linkage structure that provides a kind of planet axis to wear and tear little and the planet wheel shaft that prevents the leakage of oil of bulldozer transmission device that oil-leakage-prevention is effective in order to solve above-mentioned the deficiencies in the prior art.
To achieve these goals, the linkage structure of the planet wheel shaft that prevents the leakage of oil of bulldozer transmission device that the utility model is designed, comprise planet wheel shaft, the fixed plate that is socketed in the bearing support and the screw that is used for being connected and fixed plate and planet wheel shaft, described planet wheel shaft is comprised of upper tip and lower axostylus axostyle, and the upper end of upper tip and bearing support socket-connects, the lower axostylus axostyle and the fixed plate connecting part that it is characterized in that planet wheel shaft are provided with a concave station, and concave station is socketed with seal ring outward; Fixed plate is provided with a boss that matches with the concave station of lower axostylus axostyle with the bearing support connecting part.
For the enhanced leaktightness effect, reduce simultaneously the wearing and tearing of planet wheel shaft and bearing support center hole, the lower axostylus axostyle middle part of planet wheel shaft also is provided with an O RunddichtringO, and this O RunddichtringO is positioned at the lower end of bearing.
In order to prevent that oil from the sealing effect at screw omission and reinforcement fixed plate place, is provided with the copper packing for oil-leakage-prevention between screw and fixed plate.
The linkage structure of the planet wheel shaft that prevents the leakage of oil of bulldozer transmission device that the utility model obtains, not only effectively improved the leakage of oil situation at fixed plate place, and the wearing and tearing between planet wheel shaft and the bearing saddle bore also decrease, simultaneously, by the improvement to planet wheel shaft and fixed plate structure, so that it is convenient to change seal ring, reduced operator's difficulty, saved the time of changing seal ring.
