Pure electric vehicle low torque seal ball bearing

Pure electric vehicle low torque seal ball bearing 2019 - 05 - 14 jtekt gerth ( JTEKT） Early response trend, continuous efforts, the results are. Today to introduce you to pure electric vehicles ( EV) , petrol-electric hybrid vehicle ( HEV） Development of ball bearings with a low torque seal. The oems are trying to reduce the power consumption of the efforts, to extend the range of EV and HEV. Among them, the electric unit with bearing, lightweight, low torque is one of the topics worth to try. For EV and HEV electric unit reducer of deep groove ball bearings, oil in the environment after long time use, such as gear wear and tear drops into the bearing internal powder and lead to shorten the life of the bearing. Therefore, in the open bearing, in order to ensure the bearing life, bearing miniaturization become a difficult problem. In order to prevent wear powder into the bearing internal, generally to bearing additional sealing ring, but contact with inner ring sealing lips and sliding friction, it will make bearing of rotary torque increases, increase power consumption. Jtekt gerth ( JTEKT） The development of the product, through improved contact with the inner ring of the seal lip shape, reduce the sealing ring for shaft fastening force, a 30% reduction in both the rotation of the torque, and improved the sealing ring close to nature. And, in the sealing ring to ensure bearing foreign body resistance ability, extend the service life of the bearing based on miniaturization improved, compared with the ordinary open bearing, bearing weight loss of about 50%. These development efforts for EV and HEV has contributed to save power consumption. Anatomy of the product
