抄録

This paper deals with temperature rise of belts when they are running. The temperature rise of running belts considered to be caused by the following three reasons.<br>(1) repeated bending of belts caused by sheaves when they run into them.<br>(2) change of tension of belts when they come into tension side and sluck side alternatively.<br>(3) friction between belts and sheaves.<br>Fig. 1 and 2 show the apparatus used. A is a motor, and by means of two belts power is transmitted from A to shaft E. B and C are sheaves on which belts tested are mounted. The diameter of both sheaves is 4 inches. Shaft E can slide on guide shown by dotted line in Fig. 1. H are pulleys on which loads are mounted by these ropes. The initial tensions are applied on belts tested. Prony brake is set on shaft F. By this brake, we can put load on belts. The amount of load is calibrated.<br>We tested three kinds of B type V belts. They are 55 ins. and 72 ins. length with normal thickness, and 55 ins. length with thin thickness.<br>According to this experiment, we can find that repeated bending of belts (1) and change of tension of belts (2) have as much effects as friction between belts and sheaves on the temperature rise of belts.
