Evaluation of Handle Rotational Feeling in Fishing Reel by Coordinate Measurement and Gear Transmission Error Measurement

This report discusses how a transmission error curve is derived by a coordinate measuring machine, and the result by a coordinate measuring machine is compared with the result by a transmission error measuring machine. A vibration based on a gear pair engagement in fishing reel occurs when a handle of the reel rotates. When this vibration is large, an angler feels uncomfortable. In author’s previous reports, it is known that a rotational feeling depends on the transmission error curve. The result indicates that the rotational feeling can be improved if the accuracy of a tooth flank is improved. In order to reduce the transmission error, the error should be measured in high accuracy. In this research, a measurement method for evaluating the rotational feeling was reported using a face gear pair via a coordinate measuring machine and a transmission error measuring machine. As a result, it was confirmed that the result of measurement by the coordinate measuring machine agrees very well with the result of measurement by the transmission error measuring machine.
