Abstract

See full text

A gear reduction mechanism (1) includes a drive gear (10) having a rotation axis (L1), and a driven gear (20) driven in mesh with the drive gear (10) and having a rotation axis (L2) that is noncoplanar with the rotation axis (L1). The drive gear (10) is provided with spiral teeth, each having a tooth trace of a spiral curve having a spiral center on the rotation axis (L1) and a constant radial pitch, when viewed in the direction of the rotation axis (L1). Furthermore, the tooth profile of the driven gear (20) is set, considering a tangent angle that changes momentarily as the drive gear (10) rotates.
