<p>PURPOSE:To ensure driving of a large low-speed rotor regardless of the size of the rotor by progressing the mobile body of a reciprocating device, by push ing a pin by a hook piece so as to rotate the rotor by a predetermined angle, while making the mobile body to recede, and by repeating these operations. CONSTITUTION:When the mobile body 7 of a reciprocating device 3 is moved forward B by an air cylinder 8 along a parallel guide rail 6, since a pin 2 is pushed by a hook piece 4 in the direction A of rotation, a rotor 1 is rotated by a fixed angle. After the mobile body 7 is progressed by a fixed length of stroke, it is made to recede and returned to its initial position. In the returning, since the back of the hook piece 4 is pulled by a following pin 2 and rotated in the escaping direction C against the energization force of a spring 12, the following pin 2 is escaped. The inner end part of the hook piece 4 is hooked on the following pin 2, and these operations are repeated. A plurality of reciprocating devices 3 arranged on both sides of the rotor 1 are reciprocated so that the time phase of these devices are differentiated from each other.</p> |
