Title: Composition for working, lubrication and fluid coupling
Inventor: KATO TOMOHIRO
IPC: C10M169/04
Filed: 1993-12-28
Abstract: PURPOSE:To obtain the subject composition which change little in its viscosity with changing shearing force and gives suitable torque transmissibility by adding suitably controlled amount of a silicon oxide powder to a base oil such as polyorganosiloxane. CONSTITUTION:Silicon oxide powder in an amount of 20 pts.wt. or below is added to 100 pts.wt. base oil. A representative example of the base oil is a polyorganosiloxane having a viscosity of 50-500000mm<2>/s at 25 deg.C, and another example is a mineral oil. Because of their good dispersion stability, amorphous silicon oxide powders such as white carbon and Aerosil are desirable as the silicon oxide powders used. These powders have a mean particle diameter of 50mum or below. The shear-viscosity characteristics can be changed by changing the amount of the silicon oxide added, and especially when this amount is 5 pts.wt. or below, the rate of change in viscosity in a high-shear region and a low-shear region can be decreased. Therefore, a fluid composition which is the most suitable for a fluid coupling which must develop low torque transmissibility in a low-shear region (in a region of a low differential rotation speed) can be given.
