A split lower chamber oil guide mechanism for hydraulic steering gear housing

The invention discloses a split type lower cavity oil guide mechanism for a hydraulic steering gear housing, including a shell, a cone thread plug, a self sealing oil pipe and an upper cover. The rear of the shell is machined with an oil guide hole, interconnected with the shell of the shell, one end of the oil guide hole is machined into a cone thread, the hole is blocked by a cone thread and the other end is kept on the other end. The diameter is slightly larger than the step hole of the oil guide hole. It is used to install the self sealing oil pipe. There is a protruding platform on the edge edge of the upper cover. The bottom of the convex platform is processed out of the fixed base of the oil pipe, the center is processed out of the oil guide hole, the self sealing oil pipe is a thin-walled steel tube, and the rubber sealing material is injected into the end face of the steel pipe, and the self sealing oil pipe is loaded in the end of the pipe. In the body tail fixed seat, the other end is loaded with the upper cover and the oil guide hole fixed seat. Through the fastening of the upper cover and the shell, the oil pipe is firmly fixed in the two seat, and the interference deformation produced by the rubber sealing material at both ends of the oil pipe plays a sealing effect.
