Abstract
The invention relates to a device for improving oil leakage of a sliding bearing pedestal of a high-voltage motor. The device comprises a motor spindle and a shell, wherein the motor spindle is mounted in the shell; a sliding bearing sleeves the motor spindle; an oily ring is arranged on the sliding bearing; two oil seals are respectively arranged at two ends of the motor spindle and are positioned in the shell; and an oil separating plate is arranged between each oil seal and the sliding bearing and on the motor spindle. According to the device for improving oil leakage of the sliding bearing pedestal of the high-voltage motor, each oil separating plate is arranged between the sliding bearing and the corresponding oil seal, and overflowing of oil can be reduced greatly, so that oil leakage of the sliding bearing is improved.
Description
Technical field
The present invention relates to bearing support field, be specifically related to the device improving the leakage of oil of high-voltage motor plain bearing housing.
Background technique
When motor runs up, lubricant oil is adsorbed to the slip surface of electric machine main shaft by the band oil ring on sliding bearing from plain bearing housing, as in Fig. 1 and 2 without shown in the oil circuit 8 of oil separating plate, lubricant oil can splash in sliding bearing inside and overflow to bearing two ends in this case, a large amount of lubricant oil accumulates in for a long time in the cavity of oil sealing position and produces malleation, when malleation is greater than the sealing malleation value of oil sealing, oil sealing leakage of oil will be caused.
Summary of the invention
In sum, in order to solve existing technical problem, the invention provides the device improving the leakage of oil of high-voltage motor plain bearing housing.
The technological scheme that the present invention solves the problems of the technologies described above is as follows: the device improving the leakage of oil of high-voltage motor plain bearing housing, comprise electric machine main shaft and housing, described electric machine main shaft is arranged in described housing, and on described electric machine main shaft, cover has sliding bearing, and this sliding bearing is provided with band oil ring;
The two ends of described electric machine main shaft are respectively equipped with two oil sealings, and described oil sealing is in described housing, described electric machine main shaft corresponding between oil sealing with described sliding bearing described in each are equipped with one piece of oil separating plate.
Further, described housing comprises top bearing shell lid and lower shaft FE Tiler, described top bearing shell lid and described next week FE Tiler be mounted opposite up and down and form described housing.
Further, described oil separating plate is the circular plate be enclosed within described electric machine main shaft.
The invention has the beneficial effects as follows: the device improving the leakage of oil of high-voltage motor plain bearing housing provided by the invention, between sliding bearing and oil sealing, install oil separating plate additional, the spilling of oil can be reduced in a large number, thus improve the phenomenon of sliding bearing leakage of oil.

Fig. 3 is erection drawing of the present invention;
Fig. 4 is sectional view of the present invention;
Fig. 5 is the B-B enlarged view of Fig. 4.
In accompanying drawing, the list of parts representated by each label is as follows:
1, electric machine main shaft, 2, sliding bearing, 3, band oil ring, 4, oil separating plate, 5, oil sealing, 6, top bearing shell lid, 7, lower shaft FE Tiler, 8, oil circuit without oil separating plate, 9, have the oil circuit of oil separating plate.
Embodiment
Be described principle of the present invention and feature below in conjunction with accompanying drawing, example, only for explaining the present invention, is not intended to limit scope of the present invention.
As shown in Figure 2, improve the device of high-voltage motor plain bearing housing leakage of oil, comprise electric machine main shaft 1 and housing, described housing comprises top bearing shell lid 6 and lower shaft FE Tiler 7, described top bearing shell lid 6 and described next week FE Tiler about 7 be mounted opposite and form described housing.Described electric machine main shaft 1 is arranged in described housing, and on described electric machine main shaft 1, cover has sliding bearing 2, and this sliding bearing 2 is provided with band oil ring 3.The two ends of described electric machine main shaft 1 are respectively equipped with two oil sealings 5, and described oil sealing 5 is in described housing, described electric machine main shaft 1 corresponding between oil sealing 5 with described sliding bearing 2 described in each are equipped with one piece of oil separating plate 4.Described oil separating plate 4 is for being enclosed within the circular plate on described electric machine main shaft 1.
As in Figure 3-5, lubricant oil splashes to bearing two ends in sliding bearing 2 inside, the oil circuit 9 of oil separating plate is formed under oil separating plate 4 stops, major part lubricant oil can be stopped isolation by oil separating plate 4, prevent lubricant oil from accumulating in for a long time in oil sealing 5 cavitys and produce malleation, when malleation is greater than the sealing malleation value of oil sealing 5, cause oil sealing 5 leakage of oil.In sum, bearing support installs the spilling that oil separating plate 4 can reduce oil in a large number additional, improves sliding bearing oil leakage phenomenon
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
