Description
Technical field
The utility model is related to a kind of bearing oil feed pump, more particularly to a kind of box high-speed electric expreess locomotive bearing oil feed pump.
Background technology
Existing box high-speed electric expreess locomotive bearing generally uses external oil circuit forced-lubrication bearing, and the power-off of accident whole system occurs
When bearing can not fuel feeding, it will cause bearing bush to be damaged with shaft dry friction.Therefore it is directed to accident condition, for the guarantor of bearing
Shield generally uses two ways, and a kind of setting top petrol tank, lubricating oil enters bearing by gravity when power-off, another is to adopt
Bearing fuel feeding is given with the mode of UPS DC power supplies+straightway pump.Both modes are complicated, and configuration is more, and primary investment is also compared
It is larger.
Utility model content
In view of the above-mentioned problems, the utility model, which provides one kind, providing lubrication using motor self power for motor bearings
The bearing oil feed pump of oil.
In order to achieve the above objectives, using following technical scheme.
A kind of box high-speed electric expreess locomotive bearing fuel feeding pump configuration, including machine shaft, the cover board for covering on motor anti-drive end, confession
Oil pump, the cover board are equipped with mounting hole, and the oil feed pump includes shell, oil pump shaft, inlet port, oil-feed port, the oil suction
Mouth is connected with Lubricating oil tank, and the oil-feed port is connected with motor bearings oil passage, and the shell is fixedly connected on described
On cover board, pump means in one end and oil feed pump of the oil pump shaft is sequentially connected, the other end pass through the mounting hole with
Machine rotating shaft transmission connects.
The machine shaft is attached with oil pump shaft by small-sized shaft coupling.Small-sized shaft coupling is secured by bolts in
On machine shaft.Small-sized shaft coupling center offers keyway, and oil pump shaft is connect with small-sized coupling key.
The shell of the oil pump is equipped with mounting flange and is fixed on the cover board by the mounting flange.
It is equipped with oil suction flange at the inlet port, oil supply flange is equipped at the oil-feed port.
The bearing fuel feeding pump configuration in motor non-shaft stretching end by increasing an oil feed pump, by machine shaft itself
Rotation provides power, and driving oil feed pump carries out oil suction and fuel feeding, meets the fuel feeding needs of motor bearings, even if external circuit powers off,
Motor bearings fuel feeding is not also affected.
