    Abstract: A buffer device for reducing the impact and noise of the coupling of a roller chain and sprocket. A groove is provided adjacent the teeth of a sprocket which receives a buffer ring. The buffer ring includes an outer resiliently compressible ring and an inner spring-like ring which is not compressible, but which is capable of resilient deformation. The buffer ring is sized to very loosely fit in the groove to avoid wear concentration. The outside diameter of the buffer ring is larger than the inscribed circle of the link plates of the roller chain engaged with the sprocket.

    Abstract: A cable car winch comprising a housing, a pulley, a main gear, a pinion and a primary gear reduction unit including a pinion for driving the main gear. The winch is characterized by the fact that a hub turns around a spindle which is rigidly affixed to the housing, and that the main gear is attached to the hub. The pinion and the primary reducer form a self-aligning block with relation to the main gear and are linked to the housing by means of connecting links and articulated swing bars.

    Abstract translation: 一种缆车绞盘，包括壳体，滑轮，主齿轮，小齿轮和主齿轮减速单元，其包括用于驱动主齿轮的小齿轮。 绞车的特征在于，轮毂绕着刚性地固定到壳体的主轴转动，并且主齿轮附接到轮毂。 小齿轮和主减速器相对于主齿轮形成自对准块，并且通过连接杆和铰接摆杆连接到壳体。
