    • An encoder device includes: an encoder base; a hub rotatably arranged in the encoder base and arranged to carry an encoder disk; and an alignment device arranged to urge the hub into a predetermined axial and radial position relative to a portion of the housing, the alignment device including a contact portion arranged to contact an axial surface of the encoder base, a locating structure arranged to maintain the alignment device in a predefined radial position, a flange structure arranged to contact an axial surface of the hub and a circumferential portion of the hub, and a spring structure arranged to urge the hub axially toward the flange element, where the alignment device urges the hub into a predetermined axial and radial position relative to a portion of the encoder base, and the spring structure contacts the hub so as to form a detent, the detent allowing the alignment device to be removed from the hub by pulling the alignment device axially away from the hub.
    • 编码器装置包括:编码器基座; 毂,可旋转地布置在编码器基座中,并布置成承载编码器盘; 以及对准装置,其布置成相对于所述壳体的一部分推动所述轮毂进入预定的轴向和径向位置,所述对准装置包括布置成接触所述编码器基座的轴向表面的接触部分,布置成保持所述对准 装置处于预定的径向位置,布置成接触轮毂的轴向表面和轮毂的周向部分的凸缘结构以及弹簧结构,其布置成朝向凸缘元件轴向推动轮毂,其中对准装置将轮毂推入 相对于编码器基座的一部分的预定的轴向和径向位置,并且弹簧结构接触轮毂以形成制动器,该制动器允许对准装置通过将对准装置从轴向远离 枢纽。
