In order to face the problem of controlling the throttle motor of automobile intake and exhaust and EGR (exhaust gas recirculation system) motor;
Because the lubricating grease can enter the conveying surface when the shear force is weak; Therefore, there is a large amount of grease on the ball and track surface The grease newly developed by Japan Seiko must have strong shear force when entering the transportation surface; Therefore, the amount of grease on the ball and track surface is enough
Reduce the running in rotation time by 70% than before; In addition, the safe torque ratio has been reduced by 30% (when used at 100 ℃); It has also completed the same or higher sintering life as the previous grease. General; To reduce torque; They are run in and rotated when the motor is assembled; To reduce the initial resistance of lubricating grease and reduce the viscosity of base oil components But; The key problem of this method is not only the running in rotation consumption time; And after reducing the viscosity of base oil; The service life will be shortened when used at high temperature
Therefore; Japan Seiko reduces grease resistance by adding nano particles in grease thus; Compare with the original; Not only can it stabilize the torque faster; And the bearing can last longer even at high temperature Adding ceramic particles in grease; Thus, the components in the base oil are connected like a chain; This makes the grease more functional Detailed material designation and particle size were not released
