NTN for the Institute to participate in the "World Solar Challenge" provides special bearing

 NTN Corporation (hereafter, NTN) will provide specially designed bearings for the Institute of the University to participate in the "World Solar Challenge" international solar car race was held in Australia in October this year. NTN interaction with the Institute of the University College of Engineering increased by Mechanical Engineering Tribology workshop, and the development of the motor shaft and angular contact ball bearing as a student, "Institute of the University of automatic" support for the activities section, will participate in the first challenge.

     World Solar Challenge "is one of the largest solar car race in the world, participants race over 3021 km, through the Australian desert between Darwin and Adelaide, using the sun as the only power source. Has 20 years of history, Since 1987 began, the race attracts participants from around the world, including many universities and businesses. Institute's goal is to win in the game the first time on the podium.

     Solar car electric car, the sun's energy into electrical energy drive motor and steering tires. With minimal power dissipation structure design requires long-distance driving using only electric power obtained from solar cells. Deep groove ball bearings NTN challenges provided by the JIS 5 magnitude, which is higher than the general JIS 0 级 two levels to help improve machining accuracy. Ceramic balls has changed ball rolling contact surface curvature is optimized to reduce the contact area and achieve a lower torque, while stirring resistance with minimal low-viscosity grease has been used. This helps to reduce 50% of the torque compared to conventional products. Gangdun has been changed to non-contact rubber seals to improve driving through the desert to prepare to resist the penetration of foreign substances.

     In addition to wheel motors, NTN bearings used in the drive wheel shaft rotational torque reduction. This helps to achieve high speed with minimum power consumption, but also contribute to long-distance driving.
