Rubber spring element for bases of machines

摘要

The double T-shaped middle part consists of an upper (10) and a lower (7) middle part with intermediate spacer piece (11). A pre-tensioning arrangement (5) consisting of bolt and nut passes through the centre. To the left and right of the middle part is a triangular sectioned bracket (8,9) fixing the rubber spring element to the base (6). A rubber element (1,2) is vulcanised at an angle to the middle part centre line to each of the inward-pointing sloping side surfaces of the triangular brackets and to the parallel inner side of the upper middle part. A further spring element (3,4) is vulcanised, parallel to the middle part centre line, to the bottom part of the inward pointing base of each bracket. The other end of the spring element ends loosely in a cavity in the upward pointing part of the lower middle part.
