<p>PROBLEM TO BE SOLVED: To provide a drive transmission mechanism of tubular roller table which has a simple annular chain mounting construction, prevents tooth jumping and is easy for chain tension adjustment. SOLUTION: Third drive transmission bodies 3 are arranged to both end rotary shaft of tubular rollers (p) arranged in series at a prescribed pitch, a comb teeth like fork has a depth dimension submerging in a tubular roller (p) surface, a pair of second drive transmission bodies 2 facing each other right under the third drive transmission body 3, a band like body 4 for connecting is annularly spread to the third/second drive transmission bodies 3, 2 positioned in a pair at the upper and lower side, further a first drive transmission body 1 is horizontally arranged with directly connecting in parallel to a rotary shaft 2a of the second drive transmission 2 positioned at the lower side to have a double rotary body construction, the drive band like body 5 in contact with an outer peripheral part of the first drive transmission body 1 is annularly circulated through the first drive transmission body 1 and a tension idling gear by a prime rotary body 7.</p> |
