Secondly, the sun gear spline of the sun gear shaft can generate heat when working, the generated heat needs to be taken away through lubricating oil, and the lubricating structure can not take away the heat generated when the sun gear spline works due to insufficient entering of the lubricating oil, and can also cause the tooth surface of the sun gear spline to be glued seriously, thereby causing the reliability and the service life of the sun gear spline to be reduced, and the expected effect of design can not be achieved.
