further, the intake air 9 communicates with an air storage chamber 12.
Further, the spherical structures of the base A and the base B and the universal ball 8 form 360-degree rotation.
The working principle is as follows: the air flow is injected into the gap between the hollow shaft and the shell through the static pressure exhaust hole of the hollow shaft 5, so that the shell is suspended and rotates at high speed, and the limit rotating speed can reach 20000 r/min. The air flow flows into the gasket through the gap between the hollow shaft and the shell, flows to the bottom cover and the top cover through the closure hole of the gasket, and is discharged through the air release holes of the bottom cover and the top cover.
The characteristics and the beneficial effects of the utility model
The length of the shell and the hollow shaft of the utility model is improved to 380mm-500mm, which can effectively improve 2 to 3 times of the original production capacity. As the number of the air bearings is increased, the on-machine experiment shows that the composite yarn production function can be completed when the station is reached. The top cover, the bottom cover, the gasket and the hollow shaft are precisely matched with the air flow through the angle and the aperture, so that the precision requirements of reducing the air compression amount and the dynamic balance and the static balance of the workpiece are met. Base A and base B are connected with universal ball, and with the hollow shaft cooperation, the branch silk roller of novel structure can require 360 degrees rotational positioning along with on-the-spot process angle.
