Title:
ROCKING AND INSCRIBING MESH TYPE PLANETARY GEAR DEVICE, AND METHOD FOR IMPROVING DURABILITY OF THE SAME
Document Type and Number:
Japanese Patent JP2004301235
Kind Code:
A
Abstract:
To provide a power transmission device using a trochoid-tooth gear and an arc-tooth gear capable of achieving a long service life and maintaining high efficiency even without using grease to which sodium nitrite is added.
In this rocking and inscribing mesh type planetary gear device, grease at least including base oil of a kinematic viscosity of 10mm2/s or more at 100°C, and thickening agent as lithium complex synthesized from adipic acid is filled between an external gear and an internal gear.
