Patent number: 7634952Abstract: The rotating nut ball screw unit with lubricating arrangement has a lubricating device composed of a main body, a collar and a bearing. The main body is provided with several oil holes and is attached to the end surface of the nut. The main body is relatively rotatable with respect to the collar intercalating the bearing therebetween. An oil storage forces the lubricant into an oil reserving space surrounded by the main body, the collar and the bearing. The oil reserving space is in communication with the oil holes and allows the lubricant to be forced into the main body and then to reach the surface of the screw bolt via oil holes. The forced lubrication arrangement of the present invention ensures a better lubricating effect.Type: GrantFiled: November 26, 2007Date of Patent: December 22, 2009Assignee: HIWIN Technologies Corp.Inventors: Xin-He Chen, Chieh-Hung Tsai, Wu-Teng Hsieh
