Abstract

In these days the great power is transmitted from one shaft to another by means of a number of V belts. Sometimes twenty or thirty belts are used to transmit the power. When we looked at them, we wondered if each belt transmits the equal amount of power or not.<br>This paper deals with this problem, Fig. 1 and 2 show the apparatus used. A is a motor, and by means of the two belts, power is transmitted from A to shaft E. B and C are sheaves on which the belts are mounted. The diameter of both sheaves is 4 inches. Shaft E can slide on guide shown by dotted line in Fig. 1. H is a pulley to which the load is applied by these ropes. The initial tension is applied to the belts. Prony brake is set on shaft F. By this brake, we can put the load to the belts. The amount of load is calibrated. Then we pasted two phosphoric bronze plates on each belt at a certain distance. Fig. 3 shows phosphoric bronze plate pasted on the belt.<br>When the belts are running, these plates come in contact with the terminal of electro magnetic oscillograph. The circuit of oscillograph is closed, and the peaks are marked on the paper of oscillograph as shown in Fig. 4. By calculating the times between peaks, we estimate the length between two phosphoric bronze plates. From the distance between the two bronze plates, we can find the ratio of power transmitted to one belt, in assuming that the elongation of belt is proportional to the power transmitted.<br>Through these experiments, we can find that, when we transmit the power by several belts from one shaft to another, each belt does not generally transmit the equal amount of power.
