Tokyo, Japan, on January 22, 2013 - seiko corporation (NSK, headquarters: Tokyo, Japan, President and CEO: big mound age male) today announced that it has developed a micro * 1 resistance bearing motor used in the gas and gas used in the circulation system. NSK increase the product sales in the growing motor vehicle market in 2015, and in the global sales target 8 million yen. * 1 fretting wear occurs under the environment of the use of bearing is constantly micro fluctuation and vibration bearing, resulting in the ball raceway surface friction. Development background in recent years, it has become a pressing problem, in order to reduce harmful gas emissions, to improve the environment, improve the car fuel economy. As a result, in the car on the application of all kinds of motor have expanded, in order to achieve higher efficiency and control accuracy. In particular, the application of motor has been in the exhaust gas recirculation system and electronic throttle design, in order to reduce exhaust of nox increased. However, in such a position the use of bearing vibration from the engine and microfluctuations due to continuous forward and backward movement. For NSK, put forward a challenge, and to improve micro resistance performance opportunities. In response, NSK developed, restrain the micro through the application of a new development of grease and NSK design technology optimization of the internal design of the bearing. Product features 1. Through the inhibition of micro improved reliability. In the optimization of the grease properties, NSK makes it easier to enter the raceway surface grease flow. As a result, even when bearing the harsh conditions, resulting in continuous micro rotary fluctuation and vibration caused by oil are kept; so as to reduce the damage of bearing raceway surface by the current bearing half, provide improved reliability. 2. Keep the basic properties of the basic properties, such as friction loss and to detect the life, is equal to or greater than the current bearing. Product advantage of the products to improve the reliability of the motor used in the exhaust gas recirculation system and in automobile throttle.
