    • A tensioning roller/winder device comprising at least one roller bearing including inner and outer rings and at least one row of rolling elements between the two rings; a pulley surmounting the outer ring; and a retaining screw comprising a body and head. An abutment is provided on the body external periphery. First and second abutments are provided on the inner ring bore. The axial length between the head and the abutment equals the axial length between an inner ring radial side edge and the inner ring bore first abutment is greater than the axial length between a inner ring radial side edge opposite the screw head and the inner ring bore second abutment. The screw abutment contacts the inner ring first abutment during the body insertion into the inner ring bore in the desired direction, but contacts the inner ring second abutment during the body insertion in the undesired direction.

    • A tensioning device for a traction member, such as a belt, for an internal combustion engine, the tension device comprising a pulley rotatably mounted on an eccentric hub also rotatably mounted on a shaft. One end of the shaft comprises a shoulder against which abuts a plate for attaching the device onto the internal combustion engine. The tensioning device further comprises a torsions spring mounted around a tubular portion of the hub extending along a longitudinal direction of the hub between the hub and the attachment plate. The tensioning device also comprising a spring holder interposed between the spring and the attachment plate. An end turn of the spring is attached around an axial portion of the spring holder.
    • 用于内燃机的牵引构件(例如带)的张紧装置,张紧装置包括可旋转地安装在偏心轮毂上的滑轮,其也可旋转地安装在轴上。 轴的一端包括肩部,肩部邻接板,用于将装置附接到内燃机上。 张紧装置还包括安装在轮毂的管状部分周围的扭转弹簧,其沿轮毂的长度方向延伸到毂和附接板之间。 张紧装置还包括插入在弹簧和附接板之间的弹簧夹。 弹簧的端部转动件围绕弹簧保持器的轴向部分附接。
