This study proposes a rotary encoder-less time synchronous average using a non-linear filter for vibration analysis of gears in operation. This non-linear filter has smaller phase lag than that of conventional linear filters and a property synchroniz

The present paper describes the tooth surface temperature and the power transmission efficiency of plastic sinecurve gears in the running condition. The plastic sine-curve and involute gears were manufactured by injection molding. The running tests f

The strength of plastic greatly varies with temperature; that is, the strength increases as the temperature decreases. Therefore, the lifetime of a plastic gear can be increased by reducing the meshing-teeth temperature of the gear. The meshing-teeth

Case-carburizing of helical gears with large helix angles may form too large hardened layers near the tooth width end on the acute angle side (ACUTE-END), and adversely affect the bending fatigue strength. We investigated the bending fatigue strength

This study proposes a modification of the Matsumoto equation using a directional parameter of tooth surfaces to adapt various gear finishing processes. The directional parameters of a contact surface, which affect oil film formations, have been discu

Case-carburizing enlarges the depth of the hardened layer at the tooth width end on the acute angle side of helical gears. For the helical gears with large helix angles (Exceeding 25°), this hardened layer may lower their bending fatigue strength. T

This study proposes a stylization method for gear tooth surface using slices of 2-dimensional spectrum. Focusing on a contour (or a slice in the z direction) of the curved surface generated by the 2-dimensinal spectrum, we could approximate the conto
