Description
Technical Field

[0002] Gear transmission mechanisms have the characteristics of compact structure, durability, reliable operation, relatively accurate transmission, high efficiency, etc., and are widely used in various mechanical equipment. However, since the existing gear mechanisms rely on direct contact and meshing between gears to work, they have high wear rates and loud noises, especially under high speed conditions, they are more easily worn out and scrapped. Therefore, existing gears cannot be used under high speed working conditions (especially above 20,000 rpm). Therefore, an air static pressure high-speed gear is needed to solve these problems.
[0003] In the prior art, when an air static pressure high-speed gear is in use, an air pump draws air from the outside and achieves the effect of air pressure when discharging. Since it has no structure to process the dust in the air, when there is too much dust in the air, it will affect the discharge efficiency in the gear body and cause greater wear to the gear body when discharging, and its practicality is poor.

The frame is located at one end outside the processing box and has a fixed handle. Through the setting of the inner cavity, the dust filtered and blocked will be blocked in the inner cavity. When the frame is taken out, it is convenient to uniformly process the dust collected in the inner cavity.
[0007] Preferably, a mounting block is fixed on the top of the frame, and the mounting block is fixed to the processing box by bolts. Through the arrangement of the mounting block and the bolts, the frame can be stably installed in the processing box, which, on the one hand, achieves a sealing effect to prevent it from accidentally slipping out, and on the other hand, facilitates unscrewing the bolts, thereby taking out the frame and processing the dust collected inside it.
[0008] Preferably, air flow channels are provided in the connecting pipe and the fixed plate, and the air flow channels are respectively connected to the air outlet pipe and the air outlet hole. Through the setting of the air flow channel, the gas discharged from the air pump can be guided by the air flow channel and discharged from the air outlet hole.
[0009] Preferably, the outlet ends of the air outlet holes are respectively arranged at the tooth angles of the gear body, so that the gas is discharged from various surfaces of the gear body, forming a static pressure air cushion layer between the meshing gears, so that power can be transmitted without direct contact between the two gear teeth, thereby achieving the purpose of avoiding wear and reducing noise.
