Abstract: An electronic transmission range select actuator (ETRSA) includes a primary drive system that operates during normal operation. The ETRSA includes an output shaft that is connected to the system via a lock pin during normal operation. The ETRSA also includes a release mechanism having a secondary motor that operates during a power loss or failure of the system. The secondary motor drives a gear that rotates freely relative to the output shaft. Rotation of the gear results in axial movement of the gear toward the lock pin, which in turn causes disengagement of the lock pin from the output shaft, allowing the output shaft to rotate due to the biasing load of a torsion spring such that the output shaft is returned to the P-range position. Thus, the mechanism is configured to return the output shaft to the P-range during a power loss or failure of the first motor.

Abstract: A gear keeping the bending stress at the dedendum from becoming locally high at the time of power transmission and thereby raising the dedendum bending strength. The radius of curvature is maximum at a critical section position determined by the Hofer's 30° tangent method. Both radii of curvature from the critical section position to the first and second connecting points X1 and Y1 are constant or decreasing. In dedendum line segment 23, there are points A1 and B1 where radius of curvature is smaller than the critical section position. In the dedendum line segment 23, the maximum radius of curvature is 3 times or less the minimum radius of curvature. By a cross-sectional view, the critical section position is part of an arc, and the arc extends to the two sides of the critical section position. Thus, the maximum bending stress becomes smaller and dedendum bending strength is improved.

An improvement of the transmission efficiency is achieved due to the improved composite roughness of the gear pair. Accordingly, both of the improvement of the transmission efficiency of the gears and an improvement of the pitting fatigue life are achieved at low cost.
