A spring 49 is provided on the outer wall of the drive shaft 48.

[0023] When this turbine air motor is in use, the initial movement of the gas input and drive shaft assembly is as follows: Compressed gas is introduced through the air inlet of the front housing, and the gas enters the drive shaft assembly area through the air inlet inside the connecting body. Under the action of gas pressure, the drive shaft moves forward, pushing the clutch sleeve to rotate along the thread direction of the helical shaft, while compressing the drive shaft spring. The splined shaft is linked to the helical shaft through a type B flat key, driving the clutch sleeve to engage with the drive shaft, forming initial transmission.

[0024] Precise positioning and engagement mechanism of the drive shaft: If the drive shaft does not reach the designated position, the elastic force of the drive shaft spring will push the drive shaft forward continuously, forcing the clutch sleeve to remain engaged with the drive shaft until the drive shaft is positioned to the limit position by the shaft elastic retaining ring. When the drive shaft is in place, the piston moves to the limit position of the drive shaft, triggering the exhaust port of the connecting body to open, and the gas flows into the subsequent components (such as the turbine shaft assembly).

[0025] Power transmission of planetary gear assembly: The drive shaft assembly transmits power through the planetary gear assembly. The transmission gear in the planetary gear assembly is fixed on the insert by a round nut and linked with the turbine shaft. The internal threaded cylindrical pin passes through the carbon steel deep groove ball bearing, transmitting the rotational motion of the planetary gear to the turbine shaft, driving the primary turbine and secondary turbine to rotate at high speed. The deep groove ball bearing reduces friction during the transmission process and ensures efficient power transmission.

[0026] Sealing and gas path control: The front and rear ends of the connecting body are sealed with O-rings to prevent intake leakage; the O-ring inside the piston ensures the airtightness of the drive shaft during reciprocating motion. The body enters the turbine housing through the gear ring of the intake housing, drives the turbine assembly to do work, and then the exhaust gas is discharged through the exhaust wheel and exhaust cover.

[0027] Safety and stability design: The reaction force of the spring ensures that the drive shaft and clutch sleeve are always engaged, avoiding transmission interruption caused by gas pressure fluctuations. The shaft is secured with elastic retaining rings and elastic retaining rings to prevent axial movement and improve structural stability.
