Sealing gland room, is being provided with motor cooling wind air inlet, on the electric machine casing in the middle part of motor on the electric machine casing of drive end
Motor cooling wind air outlet is provided with, drive end barge board is provided with motor cavity, is provided with drive end barge board
Suction opeing, is provided with air outlet on the cavity of drive end sealing gland room, and one end of drive end ajutage is connected one with air outlet
Rise, the other end and the suction opeing of drive end ajutage are connected together.
Non-driven-end bearing is provided with high-speed electric expreess locomotive axle, the anti-drive end sealing gland room on the inside of non-driven-end bearing
Anti-drive end air outlet is provided with cavity, anti-drive end suction opeing is provided with anti-drive end barge board, in anti-drive end
Anti-drive end ajutage is provided between air outlet and anti-drive end suction opeing.
It is of the present utility model simple in construction, implement easy, the bearing oil that high-speed electric expreess locomotive is solved well is easily let out
The problem of dew.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is described in detail below in conjunction with the accompanying drawings：
