To provide an electric motor and/or a power generator especially for a railway vehicle, with which a revolution speed of a shaft is increased without increasing a frequency of maintenance work and lowering reliability of an electric motor.SOLUTION: An electric motor and/or power generator (1) especially for a railway vehicle according to the present invention, comprises: a housing (10); a movable shaft (16) revolving around an axis (X-X') with respect to the housing (10); and at least two tilted bearings (18, 20) connecting the shaft (16) and the housing (10) with each other. Each of the at least two tilted bearings (18, 20) includes; an outer ring (30) attached to the housing (10); an inner ring (32) attached to the shaft (16); and a plurality of balls (34). Each of the balls (34) defines an outer contact track of the outer ring (30) and an inner contact track of the inner ring (32), with the outer contact track being offset in an axial direction with respect to the inner contact track.SELECTED DRAWING: Figure 1

    【課題】保守作業の頻度を増やすことも電動機の信頼度を低下させることもなしにシャフトの回転速度を高めるための、特に鉄道車両用の電動機および/または発電機を提供すること。【解決手段】本発明は、ハウジング(10)と、ハウジング(10)に対して軸(X-X')の周りを自転する可動シャフト(16)と、シャフト(16)とハウジング(10)を連結する少なくとも2つの傾斜軸受(18、20)とを備える、特に鉄道車両用の電動機および/または発電機(1)であって、その2つの傾斜軸受(18、20)の各々が、ハウジング(10)に取り付けられた外輪(30)と、シャフト(16)に取り付けられた内輪(32)と、複数のボール(34)とを備え、ボール(34)の各々が、外輪(30)の外側接触軌道と内輪(32)の内側接触軌道とを画定し、外側接触軌道が、内側接触軌道に対して軸方向にオフセットされた、電動機および/または発電機(1)に関する。【選択図】図1
