A conventional gear device for a railway vehicle will be explained with reference to the drawings. FIG. 2 is a sectional view showing a conventional gear device for a railway vehicle. In the figure, 1 is an electric motor, and 2 is a connection between the motor shaft 1a of the motor 1 and a small gear shaft 7 that is integrally formed with a small gear of the gear device. It is a flexible joint.
3 indicates an axle, and 4 indicates a wheel. Reference numeral 5 denotes a gear box, one end of which is supported from the truck frame by a gear box hanging device (not shown). 6 is a large gear fitted to the axle 3, 8 and 9 are gear box support bearings, 10 is a small gear bearing on the motor side (hereinafter referred to as PM side bearing), and 11 is a small gear bearing on the wheel side (hereinafter referred to as (referred to as PW side bearing),
Reference numeral 12 indicates a bearing cover on the motor side, and reference numeral 13 indicates a bearing cover on the wheel side. Further, although not shown, lubricating oil is stored in the gear box 5, and each bearing is lubricated by the oil supply caused by the rotation of the large gear 6.
かくして電動機１の回転力は、可撓継手２を介

車６、車軸３を経て車輪４を回転させる構造とな
つている。 Thus, the rotational force of the electric motor 1 is transmitted to the pinion shaft 7 via the flexible joint 2, and further rotates the wheel 4 via the pinion, the large gear 6, and the axle 3.
ところで、上述したように従来の歯車装置にお

As described above, in the conventional gear device, the lubrication of each bearing is performed by splashing oil due to the rotation of the large gear 6. However, when starting up quickly from a low temperature, the temperature of the pinion bearings 10 and 11 increases.
The PW side bearing 11 always experiences a greater temperature rise than the PM side bearing 10, which can cause the PW side bearing 11 to seize.
このPW側軸受１１の温度が高くなる理由は、
PM側軸受１０の場合は小歯車軸７が動力伝達側
であるため軸受の発生熱は内輪から小歯車軸７を
介して可撓継手２側に伝達放熱されるのに対し
て、PW側軸受１１では車輪側軸受フタ１３が盲
フタであり、軸受内輪から小歯車軸７を伝わる熱
放散の経路がないためである。 The reason why the temperature of this PW side bearing 11 becomes high is as follows.
In the case of the PM side bearing 10, since the pinion shaft 7 is on the power transmission side, the heat generated in the bearing is transferred from the inner ring to the flexible joint 2 side via the pinion shaft 7 and is dissipated, whereas in the PW side bearing In No. 11, the wheel-side bearing lid 13 is a blind lid, and there is no path for heat dissipation from the bearing inner ring to the small gear shaft 7.
本考案はかかる点にかんがみなされたもので、
PW側軸受１１の発熱を放散して、温度上昇を低
下させ焼付きなどの事態の発生を防止する歯車装
置を提供することを目的とする。 The present invention was developed in consideration of these points.
It is an object of the present invention to provide a gear device that dissipates heat generated in a PW side bearing 11, reduces temperature rise, and prevents occurrence of situations such as seizure.
