ある。Conventionally, most bearings for air spinning machines have been sealed with grease, and with this method, there is a large power loss due to the viscous resistance of the grease at the beginning of the startup of the air spinning machine.
The drawback is that production cannot begin unless a break-in operation is performed for about an hour.Also, in terms of cooling, the grease-sealed method does not provide sufficient cooling during high-speed operation, which can cause bearing seizure. was. Recently, one-stroke lubrication systems have been seen, but they require a separate pump to send the lubricating oil, piping to each bearing without oil leakage, and the lubricating oil must be collected and reused. The problem is that there is nothing to use, and a large amount of lubricating oil is consumed.

のである。The present invention solves the above-mentioned drawbacks, and is capable of efficiently cooling the bearings that support the spinning printer as air spinning machines increase in speed (as well as eliminating the need for a break-in operation at the initial stage of startup, and requiring a separate oil supply pump). The present invention provides a bearing device for an air spinning machine that efficiently uses lubricating oil and does not require any piping equipment.

In addition, a nozzle (2) that communicates with the oil storage chamber Qυ is installed in a protruding manner at the lower part of the internal sleeve located between the turbine and the bearing, and the outlet of the nozzle (2) is connected to the turbine (
2) A negative pressure is created by passing the airflow from the lubricating oil tank i10υ, and the lubricating oil is sucked out from the oil storage i10υ, and the sucked out lubricating oil forms a cest and is sprayed onto the ball of the bearing, which serves to lubricate the bearing. Furthermore, a shredding plate (t4tw-inserted and fixed on the evening shaft) close to both ends of the inner sleeve on the opposite side of the bearing facing the turbine, and shredded IFk
An oil condensation space 0 communicating with the air chamber (to) is carved in the upper part of 4 between the external sleeve and an oil condensation space 0 connected to the air chamber (to) is carved from both ends of the cylindrical lid rptt>tutor (1) in the vicinity of the shredded plate. A bearing device for an air spinning machine is constructed by inserting and screwing the crotch into both ends of the outer sleeve (7) into nine internal threads.

The airflow returns along the wall to the oil storage chamber under the action of gravity, and the airflow that has been transported together with the lubricating oil is sent to the air chamber in the oil condensation space ta. In this way, the lubricating oil and air are cooled in the oil storage chamber and the air chamber, respectively, and the lubricating process is completed.

のである。Since the present invention is configured as described above, the driving load is smaller than when using grease lubrication, which reduces power costs and has the advantage that production operation can be carried out from the time of startup. Because it is lubricant,
Compared to grease lubrication, the cooling efficiency is much better, allowing the air spinning machine to operate at higher speeds, and extending the life of the bearing device. Furthermore, it does not require special piping equipment or pumps for supplying lubricating oil, and has the advantage that existing air spinning machines can be used without modification.
