SHAFT SUPPORT MECHANISM AND THREE-WAY ROLLER

PURPOSE:To improve adjustment accuracy by disposing a tie rod pin having notched portions by means of a bolt in such a way as to be axially adjustable, and by adjustably supporting a shaft by means of the tie rod pin via inclined surfaces that have the same angle as that of the notched portions. CONSTITUTION:A tie rod pin 15 having V-shaped notches 17 is disposed at right angles to a shaft 11 with a clearance S formed between them to enable movement in the direction of the axis of the tie rod pin. Adjustment bolts 18 are inserted into pressure plates 13 and 14, and are screwed into the pin 15. The position of the tie rod pin can be adjusted in another direction by fastening either upper or lower bolts 18. Chocks 19 are provided with inclined surfaces that have the same angle as the notches 17, whereby the lateral fine adjustment of the shaft can be effected. A tie rod pin 16 having V-shaped notches 20 is disposed at right angles to the shaft with a clearance formed between them to enable movement in the direction of the axis of the tie rod pin. The adjustment bolts inserted into the plates 13 and 14 allows the positional adjustment of the tie rod pin. The chocks 19 are provided with the inclined surfaces that have the same angle as that of the notches 20, so that the lateral fine adjustment of the shaft can be effected.
