specific Embodiment approach 1

[0040] Specific implementation mode one: combine Figure 1 to Figure 10 Describe this embodiment, a high-precision rotating ring-shaped part of this embodiment supports an air-floating static balance device, which includes an air-floating cavity 1, an end cover 2, a support 3, a support column 4, and a disc seat 5 and two axial positioning devices 6, the interior of the air flotation chamber 1 is provided with a working air chamber 1-2 and a plurality of cylindrical air intake passages 1-3 communicated with the working air chamber 1-2, and the working air chamber 1-2 is located at one end of the air flotation cavity 1, the top of the air flotation cavity 1 is processed with a circular arc-shaped working surface 1-1, and the working surface 1-1 is processed with a plurality of cylindrical air intake channels 1-3 connected The air inlet hole 1-4, the curvature of the working surface 1-1 of the air flotation cavity 1 is the same as the curvature of the inner ring of the rotating ...

specific Embodiment approach 2

[0041] Specific implementation mode two: combination figure 1 and image 3 To describe this embodiment, the angle of the center of the circle corresponding to the arc of the cross section of the working surface 1 - 1 in this embodiment is 60° to 180°. Other compositions and connections are the same as in the first embodiment.

specific Embodiment approach 3

[0042] Specific implementation mode three: combination figure 1 and figure 2 To describe the present embodiment, the distribution positions of the plurality of cylindrical air intake passages 1-3 in the present embodiment are arranged in a gradually sparse manner from the middle to both ends along the circumferential direction. In this way, the number of air inlet holes 1-4 on the top of the working surface 1-1 of the air flotation chamber 1 is large, which can improve the bearing capacity of the present invention. Other compositions and connections are the same as those in Embodiment 1 or Embodiment 2.

Abstract

The invention discloses a high-precision rotary ring-shaped part inner supporting air floating type static balance device, and belongs to the field of rotary ring-shaped part static balance. The problems that an existing air floating type static balance device for the rotating ring-shaped parts is only suitable for occasions where the parts are short in width, and static balance cannot be conducted on the rotating ring-shaped parts long in width are solved. The bottom end of the end cover is rotatably connected with the top end of the support, the side, away from the working air cavity, of the air floatation cavity is connected with the round base plate through the supporting column, the levelness of the air floatation cavity can be adjusted through the supporting column, and the two axial positioning devices are installed on the two sides of the air floatation cavity in the axis direction correspondingly. External supplied air can enter the working air cavity through the air supply hole, cylindrical inlet air passes through the air inlet hole, an air film with bearing force is formed between the working surface and the inner surface of the rotating ring-shaped part, and the rotating ring-shaped part is floated to conduct static balance. The static balance device is suitable for static balance of the rotating ring-shaped parts, and static balance of the rotating ring-shaped parts with different widths can be achieved.

Description

technical field [0001] The invention relates to a static balancing device, in particular to a high-precision rotating ring-shaped internally supported air-floating static balancing device, which belongs to the field of static balancing of rotating ring-shaped parts. Background technique [0002] Rotating ring parts (such as ring gears, bushings, etc.) are widely used in manufacturing, navigation, aviation, aerospace and other fields. In the manufacturing process of rotating ring parts, due to the influence of factors such as material defects and design errors, static unbalanced mass will inevitably occur. During the rotation of the rotating ring-shaped parts with the main shaft, these static balance masses will cause abnormal vibration of the system, aggravate equipment wear, and even catastrophic damage to the system, seriously reducing the safety and reliability of the system. Static balancing technology can reduce the static unbalanced quality of rotating ring parts and ...
