Abstract:
1. A rotary bearing with current feed-through means for a sausage clipping machine, the rotary bearing comprising: a bearing casing and a bearing shaft rotatably accommodated therein, wherein the bearing casing and the bearing shaft are at least partially made from an electrically conducting material, at least one current path which is passed through the bearing casing and the bearing shaft and which is electrically insulated at least in relation to the electrically conducting portions of the bearing shaft and the bearing casing and which has at least one outer connecting terminal provided on the bearing casing and the bearing shaft respectively, and wherein the current path has a current path bolt of electrically conducting material which is fitted in a through bore in the bearing shaft, wherein at its one end the current path bolt projects from the bearing shaft and forms the outer connecting terminal of the bearing shaft and at its other end has a touching contact region which is in electrically conducting relationship with a touching contact region of the bearing casing to form the touching contact portion, of the current path, wherein the touching contact portion of the current path bolt is elastically prestressed by means of a spring element in the direction of the touching contact region of the bearing casing, and wherein the spring element is electrically insulatedly supported at the end of the bearing shaft which is fixed in its axial position in the direction of the touching contact region of the bearing casing.
