TL;DR: In this article, the authors propose to reduce noise and prevent crack of chain rollers by supporting each bucket with any two of the link plates of a chain rotatably, and allowing the bucket to rotate freely when chain roller collides with sprocket.
Abstract: PURPOSE:To reduce noise and prevent crack of chain rollers by supporting each bucket with any two of the link plates of a chain rotatably, and allowing the bucket to rotate freely when chain roller collides with sprocket CONSTITUTION:A chain 1 consists of a plurality of link plates 3, whcih are coupled by rollers 5 and bushings endlessly Here each of the buckets 6 is furnished in such a manner as getting over two adjoining plates 3a, 3b over and below, and the upper and lower mounting parts 8, 9 of this bucket 6 are supported at the plates 3a, 3b rotatably through mounting pins 10, 11, respectively Accordingly if any roller 5 collides with sprocket, the bucket 6 rotates round the mounting pin 10 separately from the link plate 3a Thus the collision energy generated between the chain 1 and sprocket can be lessened to attain the intended purpose
