US20080234150A1 GREASE COMPOSITION FOR CONSTANT VELOCITY JOINT AND CONSTANT VELOCITY JOINT 有权
用于恒定速度接头和恒定速度接头的润滑脂组合物

GREASE COMPOSITION FOR CONSTANT VELOCITY JOINT AND CONSTANT VELOCITY JOINT
摘要：
The invention provides a grease composition for constant velocity joint containing the components (a) to (g) below and a constant velocity joint containing said composition. (a) a diurea thickening agent having the following formula (1): R1NH—CO—NH—C6H4-p-CH2—C6H4-p-NH—CO—NHR2   (1) wherein R1 and R2 may be the same or different and represent C8-C20 alkyl groups, (b) an ester synthetic oil, (c) a mineral oil and/or a synthetic hydrocarbon oil, (d) a molybdenum dialkyldithiocarbamate, (e) molybdenum disulfide, (f) a polytetrafluoroethylene, and (g) a zinc dithiophosphate compound. The grease composition of the invention reduces variations in rotational resistance of the constant velocity joint at a low temperature.
摘要（中）：

本发明提供含有下述组分（a）至（g）的等速万向节润滑脂组合物和含有所述组合物的恒速接头。 （a）具有下式（1）的二脲增稠剂：<？in-line-formula description =“In-line formula”end =“lead”？> R 1 NH-CO- NH-C 6 H 4 -S-CH 2 -C 6 H 4 H / β-NH-CO-NHR 2（1）<？in-line-formula description =“In-line Formulas”end =“tail”？>其中R 1， O 2和R 2可以相同或不同，表示C 8 -C 20烷基，（b）酯合成油， （c）矿物油和/或合成烃油，（d）二烷基二硫代氨基甲酸钼，（e）二硫化钼，（f）聚四氟乙烯和（g）二硫代磷酸锌化合物。 本发明的润滑脂组合物减少了等速万向节在低温下的旋转阻力的变化。
