Technical Field

[0001] The utility model belongs to the technical field of engineering machinery inspection, and specifically relates to a special sealing installation tool for a rotary vane steering gear. Background Art

[0002] Currently, no additional tooling is required for the installation of special seals for rotary vane servos. However, during installation, the gap between the cylinder block and the rotor needs to be enlarged or reduced to meet installation requirements.

[0003] When the gap between the cylinder body and the rotor is enlarged to prevent damage to the seal during installation, it will lead to a decrease in sealing performance and efficiency. In addition, although the installation is easier after the gap between the rotor and the cylinder body is enlarged, the efficiency of the servo will be greatly reduced, the leakage will increase, and the service life of the servo will be shortened.

[0004] When the gap between the cylinder body and the rotor is adjusted to a smaller size, the installation becomes more difficult and requires repeated reinstallation, which can easily lead to damage to the dedicated seal and significantly increase the cost. Utility Model Content
