Inlet and exhaust control motor bearings

NSK for motor control of automobile exhaust throttle and EGR ( ExhaustGasRe - circulationSystem) Motors, developed a low torque of the sealed bearing grease. In general, in order to reduce the torque, rotate all is to get up to speed when the motor assembly, in order to reduce the initial resistance grease, reduce the viscosity of base oil composition. However, this issue is: not only in rotation time consuming, and reduce the viscosity of base oil, when used in high temperature will shorten the service life. Therefore, the company by adding the nano-scale particles within the grease to reduce grease resistance. As a result, compared with the original, can not only stable torque more quickly, and even at high temperatures can keep long life. Added in the grease is ceramic particles, 'which will be the base of oil composition is like a chain to connect, so that the performance of the grease stronger'. Specific material name, and particle size. Grease before due to the shear force is weak can also enter the transport, so the ball and more grease on the surface of the attachment. And the new development of grease in the transport must have strong shear force, so the ball and the amount of grease attached on the surface of the rail was just right. So you can make the initial torque stable in a short time, rotate the running-in time reduced by 70% than before. In addition, the constant torque 30% less than before, When used under 100 ℃) 。 But also to achieve the same as the previous grease or higher sintering life.
