One can draining axle box end cap

Technical field

This utility model relates to the axle box end cap of locomotive, subway, motor train unit bogie, particularly one can draining axle box end Lid.

Background technology

Locomotive, subway, EMUs etc., during operation, have during axle box end cap and produce into water phenomenon, if can not send out in time Now intaking and carry out draining, on the one hand water can enter bearing, causes bearing failure, on the other hand easily causes being arranged on axle box end The damage of the shaft end equipments such as the velocity sensor of lid, grounding device.And traditional axle box end cap does not has drainage arrangement, can only pass through The way opening axle box end cap checks whether that, into water and draining, workload is bigger.

Utility model content

Technical problem to be solved in the utility model is, not enough for prior art, it is provided that a kind of inspection is intake and row What water was simple to operation can draining axle box end cap.

For solve above-mentioned technical problem, the technical scheme is that one of this utility model can draining axle box end cap, its It is provided with foremost and is easy to the circular locating ring that axle box bearing axially positions, and the aperture surface of the periphery of this locating ring and axle box Match and realize the radial direction location of axle box end cap；The rear end of this locating ring arranges the axle box matched with axle box one end and coordinates Face, this axle box cooperation face is equipped with multiple end cap installing hole；This axle box coordinates the outside in face to arrange lid, this lid Arranging shaft end equipment installing hole on outer face, and the bottom of this lid is provided with tank, this bottom of gullet arranges and blocks up with screw plug, pad The osculum lived.

Being improved to further of such scheme, described shaft end equipment installing hole is evenly distributed on lid outer face.

Being improved to further of such scheme, on described axle box cooperation face, average mark is furnished with multiple fabrication hole.

Being improved to further of such scheme, described shaft end equipment installing hole is multiple.

This utility model axle box end cap locating ring foremost is round boss, plays the axial positioning action of axle box bearing, Locating ring periphery plays and guides and the radial direction location of axle box end cap；Axle box cooperation face is bolted and can guarantee that axle box end Lid is closely joined together with axle box；Lid can guarantee that shaft end equipment and axle box by shaft end equipment installing hole, bolt connection End cap is closely joined together；When dismantling axle box end cap difficulty, axle box end cap is ejected by available fabrication hole, and dismounting is simple, Reduce dismounting difficulty；This utility model, can draining in time, at ordinary times osculum use by offering osculum bottom axle box end cap Screw plug is blocked, and can prevent osculum from intaking；During draining, open screw plug, the water within axle box can be discharged.By osculum it is No have water to discharge, and can quickly judge whether axle box intakes, simple to operate, workload is few, has ensured axle box bearing, shaft end equipment Safety, reliability.

This utility model is simple and compact for structure lightly, easily manufactured, it is easy to check whether that, into water, drainage is good, operation letter Single, improve the safety and reliability of axle box bearing, shaft end equipment, be suitable for larger range of user and the market demand, add Strong competitiveness, it is easy to popularization and application.
