Do you need to pay attention to the suspension of assembly of automobile power steering gear?
I wonder if you have noticed that there are many problems to pay attention to when you stop the assembly of the automobile power steering gear. Once you are a little careless, you will bury the problem of potential safety hazards. Therefore, our pneumatic ball valve company reminds you to be careful in assembly. The assembly steps and precautions are as follows:? Install the control valve. Install the torsion bar, stub column and rotor into the worm, install the seal ring and wear ring into the valve housing, install the worm and thrust ball bearing into the valve housing, and install the ball bearing, oil seal, dust cover, etc. on the adjusting nut; Adjust the axial clearance of worm shaft to 0.01~0.02mm, and then tighten the nut? Install the piston. Insert the worm into the piston, align it with the spiral groove and place it in parallel, insert the steel ball into the hole from the guide tube, and gradually rotate the screw until the first steel ball reaches the opposite steel ball guide tube hole. The remaining steel balls are arranged in the guide pipe. Fill the guide pipe groove with hydraulic oil, insert the steel ball guide pipe into the piston guide pipe bearing hole and fix it? Install the piston rings. After the wear ring and seal ring are installed on the piston, a little hydraulic oil can be coated on the inner wall of the cylinder housing and the piston, and then the piston can be installed into the cylinder housing. Put a seal ring on the valve housing and fix it on the cylinder housing. Pay attention to the installation direction so that the valve housing is opposite to the cylinder housing oil hole? Install the sector gear shaft. Turn the stub so that the piston rack is in the middle of the cylinder housing, insert the sector gear shaft, and assemble the sector gear shaft needle bearing seal ring, retaining ring and oil seal, and install the side cover and adjusting screw. Adjust the gap between the sector tooth and the piston to 0.10~0.45mm, and the axial gap between the sector tooth is not more than 0.35mm. Tighten the adjusting screw nut? Install the steering pitman arm according to the assembly mark, and the torque of the fixing nut is 300~400N · m; Discharge the air again. Loosen the steering wheel. The hydraulic pressure is 0.5MPa, and the pressure at the locking position of the steering wheel is 10.5MPa. Otherwise, it should be adjusted or repaired.
