Method for feeding grease composition for grease-feeding

摘要

Disclosed is a method for feeding a grease composition for grease-feeding to bearing units comprising 35 to 85 wt. % of fluorine-based grease and 65 to 15 wt. % of fluorine-based organic solvent; the method comprising jetting the grease composition into an inner portion of a bearing unit, such as a bearing for a conveyor chain having a grease-feeding hole, so as to feed the fluorine-based grease in an amount accounting for 10 to 45 volume % of the space volume in the bearing. According to the grease-feeding method, the grease composition for grease-feeding can be effectively applied to a bearing unit having a grease-feeding hole (nipple), thereby can be sufficiently supplied to a lubrication part, and allows grease-feeding without leakage from the bearing unit.

1. A method for feeding a grease composition comprising 35 to 85 wt. % of fluorine-based grease and 65 to 15 wt. % of fluorine-based organic solvent; the method comprising jetting the grease composition into an inner portion of a bearing unit having a grease nipple through a grease-feeding hole of the grease nipple so as to feed the grease in an amount accounting for 10 to 45 volume % of a space volume in the bearing and allowing the fluorine-based organic solvent to volatilize after said jetting so that the fluorine-based grease returns to an original hardness the fluorine-based grease had without the fluorine-based organic solvent.
