| Zusammenfassung: | The utility model relates to a steering gear with an oil seal guide assembly sealing mechanism, which comprises a working cylinder (1), and two ends of the working cylinder (1) are respectively equipped with a piston valve assembly (2) and an oil seal guide assembly (3). The steering gear is characterized in that the end of the working cylinder (1) equipped with the oil seal guide assembly is equipped with a plurality of rolling grooves. The rolling grooves can guarantee the concentricity of the working cylinder and the oil seal guide assembly, the oil seal guide assembly can be directly pressed into the working cylinder, the oil seal guide assembly can be limited by the friction generated by interference fit between a limiting sealing ring and the working cylinder, and press fit is avoided after the oil seal guide assembly is located, thereby reducing process procedures, and increasing working efficiency. |
