[0031] This application discloses a high-speed oil seal structure for a transmission, such as... Figure 1 As shown, the device includes a frame body 1, with a through hole 11 in the middle. A groove 12 is formed on the wall of the through hole 11, with the opposite side walls of the groove 12 being parallel. A bidirectional oil return line is provided on the wall of the groove 12, and there are four sets of bidirectional oil return lines on the wall of the through hole 11, each set consisting of five symmetrical lines. The groove 12 can limit the oil flow, allowing it to accumulate within the groove 12. Furthermore, when the vehicle reverses, the oil in the groove 12 can flow back, reducing the possibility of leakage and improving the sealing performance of the oil seal.
