[0023] like Figure 1-4 As shown, the present invention provides a technical solution: a turbine air motor, comprising a planetary gear assembly 1, a housing front cover assembly 14, an intake valve core assembly 29, a hub assembly 44, a drive assembly 4, a piston assembly 9, and an air guide wheel assembly 20;

[0024] The planetary gear assembly 1 includes a planetary gear carrier, planetary gear pins, a resilient cylindrical pin-straight groove heavy-duty bearing, planetary gear washers, planetary gears, a needle roller bearing with an inner ringless stamped outer ring, and a shaft elastic retaining ring. In the planetary gear assembly 1, the planetary gears are axially fixed by planetary gear washers and connected to the planetary gear pins by the needle roller bearings with an inner ringless stamped outer ring. The planetary gear pins are fixedly connected to the planetary gear carrier by the resilient cylindrical pin-straight groove heavy-duty bearing and axial displacement is ensured by the shaft elastic retaining ring.

[0025] The housing front cover assembly 14 includes an O-ring, a housing front cover, an inner exhaust screen, a bearing pressure plate, an external hexagonal screw, and a single-lip oil seal. The single-lip oil seal is located inside the housing front cover and is tightly connected to the long positioning ring 41 to ensure sealing. The inner exhaust screen and the bearing pressure plate are fixed together to one side of the housing front cover by the external hexagonal screw. The O-ring connects the housing front cover to the gear ring 13 and the housing front cover to the turbine housing 23. The housing front cover is connected to the turbine shaft 17 through a deep groove ball bearing 18.

[0026] The intake valve core assembly 29 includes an intake valve core, an O-ring, and an O-ring. The intake valve core of the intake valve core assembly 29 is sealed to the intake wheel 24 by means of the O-ring; the intake valve core assembly 29 is in cooperation with the intake valve spring 27 and the intake valve spring washer 30, preset the working atmospheric pressure, and form an automatic reset system.

[0027] The wheel hub assembly 44 includes a wheel hub, a wheel hub bushing, a single-lip spring-loaded oil seal, and an O-ring. The wheel hub assembly 44 is connected to the connector 8 via an internal hexagon head screw 43; the wheel hub assembly 44 forms an O-ring seal connection with the connector 8 via an O-ring 10; the wheel hub assembly 44 is axially fixed by an imperial heavy-duty axle retainer 46 and a flat washer 45; the wheel hub assembly 44 is connected to the piston assembly 9 via the O-ring 10.

[0028] The drive assembly 4 and the planetary gear assembly 1 are connected by a spline for transmission: the wheel drive assembly 4 is connected to the open ring 47 and is pushed forward by the piston assembly 9; the drive assembly 4 cooperates with the drive shaft spring 5 to provide the reset power.

[0029] The piston assembly 9 and the connecting piece 8 are sealed by the O-ring 10 to ensure airtightness; the piston assembly 9 cooperates with the open ring 47 to push the drive assembly 4 and prevent wear; the piston assembly 9 and the hub assembly 44 are sealed by the O-ring to ensure airtightness.

[0030] The air guide wheel assembly 20 is axially fixed in conjunction with the short positioning ring 37; the air guide wheel assembly 20 is in conjunction with the deep groove ball bearing 18 and rotates on the turbine shaft; the air guide wheel assembly 20 is connected to the bearing pressure plate 36 by the external hexagonal screw 35 to fix the deep groove ball bearing.

[0031] When the turbine motor is in use, gas enters through the inlet of the turbine housing 23, first passing through the intake wheel 24. At this time, the intake valve core assembly 29 ensures a sealed connection with the intake wheel 24 via an O-ring. The intake valve spring 27 and intake valve spring washer 30, in conjunction with a preset working atmospheric pressure and an automatic reset system, ensure stable gas delivery. Subsequently, the gas drives the primary turbine 21 and secondary turbine 19 to rotate, which in turn drives the turbine shaft 17 to rotate synchronously via the transmission action of the square key 22. The turbine shaft 17 is connected to the front cover of the housing front cover assembly 14 via a deep groove ball bearing 18. Simultaneously, the O-rings in the front cover assembly 14 seal the front cover and gear ring 13, and the front cover and turbine housing 23 respectively, ensuring no gas leakage and smooth rotation of the turbine shaft 17. The turbine shaft 17 then meshes with the planetary gears of the planetary gear assembly 1 for transmission. The planetary gear is axially fixed by planetary gear washers, and connected to the planetary gear pin by a stamped outer ring needle roller bearing without an inner ring. The planetary gear pin is fixed to the planetary gear carrier by a flexible cylindrical pin with a straight groove and a shaft elastic retaining ring to limit axial displacement, ensuring that power is transmitted to the planetary gear carrier without loss. The planetary gear carrier transmits power to the drive assembly 4, which is located inside the nose housing 3 and is connected to the needle roller bearing 2, through a spline. The drive assembly 4 runs under the push of the piston assembly 9, and at the same time, the drive assembly 4 obtains the reset power by means of the drive shaft spring 5. During this period, the hub assembly 44 is connected to the connector 8 by an internal hexagonal head screw 43, and is axially fixed by an imperial heavy-duty shaft retaining ring 46 and a flat washer 45. The air guide wheel assembly 20 is axially fixed by a short positioning ring 37, and rotates on the turbine shaft in cooperation with a deep groove ball bearing 18. The deep groove ball bearing 18 is fixed by an external hexagonal head screw 35 and a bearing pressure plate 36, ultimately achieving precise power transmission and stable motor operation.

Furthermore, it should be noted that the components of the present invention are not limited to the overall application described above. Each technical feature described in the specification can be used individually or in combination as needed. Therefore, the present invention naturally covers other combinations and specific applications related to the inventive points of this case.
