Title:
揺動内接噛合型遊星歯車装置及びその耐久性向上方法
Document Type and Number:
Japanese Patent JP4328120
Kind Code:
B2
Abstract:
In the oscillating internal-meshing planetary gear system of the present invention, a space formed between a external gear (52) and a internal gear (8) is filled up with a grease (14), which contains base oil whose kinetic viscosity is equal to or higher than 10 mm<2>/s at 100° C. and lithium complex thickener synthesized from adipic acid. Such construction of the oscillating internal-meshing planetary gear system of the present invention provides a power transmission system using a trochoidal tooth profile gear and a circular-arc tooth profile gear that enables to realize a long life and keeping a high efficiency, even without applying grease containing sodium nitrite.
