Detailed Description
The preferred embodiments of the present utility model will be described in detail below with reference to the attached drawings so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making clear and defining the scope of the present utility model.
Examples: 1-3, a Roots blower gas seal piston ring mounting tool comprises a mounting tool body 1, a gas seal ring fixer 2 and a piston ring 3, wherein the piston ring 3 is mounted on the gas seal ring fixer 2, and the gas seal ring fixer 2 is mounted on the mounting tool body 1.
The piston ring 3 is provided with four, the air seal ring fixer 2 is provided with a piston ring mounting groove, and the piston ring 3 is mounted on the piston ring mounting groove.
The installation tool body 1 has a cylindrical shape.
The installation tool body 1 is divided into a driving-side gas seal ring installation tool and a non-driving-side gas seal ring installation tool.
The outer diameter machining size of the driving side air seal ring mounting tool is 0.10mm smaller than the inner diameter of the bearing seat, and the inner diameter machining size is 0.10mm larger than the outer diameter of the air seal ring fixer.
The end face of the non-driving side air seal ring installation tool is provided with a step, and the depth is 8.24mm.
Working principle: when the air seal ring fixer 2 is assembled back, the piston rings are firstly arranged in the grooves of the air seal ring fixer, and the outer diameters of the four piston rings 3 become larger under the action of self tension, exceed the inner diameter of the ring seat, and cannot be assembled back into the ring seat smoothly; the piston rings 3 on the air seal ring fixer 2 are embedded into the manufactured installation tool body 1 one by one, taking the direction of openings into consideration; then the air seal ring fixer and the special tool are integrally assembled back, the end face of the special tool is tightly attached to the end face of the ring seat during the assembly back, and the air seal ring fixer on the inner side of the special tool is symmetrically and uniformly knocked by a tetrafluoro rod, so that the piston ring can smoothly transition, is in seamless butt joint and smoothly enters the mounting position of the ring seat;
