Description

Technical Field

[0001] The utility model relates to the technical field of turbocharging equipment, and more specifically to a turbocharger output shaft connecting mechanism. Background Art

[0002] A turbocharger is actually an air compressor that increases the air intake by compressing air, thereby increasing the engine's air intake and output torque. The existing connection between the impeller and the drive shaft is generally fixed by welding, crimping, or bolting. This connection method is not convenient for quick disassembly when the impeller is damaged, which affects the convenience of subsequent inspection and maintenance.

[0003] The existing announcement number is CN220168027U, and its name is a turbocharger output shaft connection mechanism, which includes an axle and a drive shaft. Blades are arranged on the outside of the axle, an output pin is fixed on the side of the drive shaft close to the axle, and a locking sleeve is also connected to the end of the output pin away from the drive shaft, and locking bolts are arranged inside the locking sleeve and the output pin; a connecting through hole is opened through the inside of the axle, a docking groove is formed inside the connecting through hole, a limiting groove communicated with the docking groove is formed inside the connecting through hole, and a first locking groove is also formed on the inside of the connecting through hole, which has the characteristics of improving the stability of the connection while facilitating disassembly and reducing the replacement cost.

However, when the impeller is used at high speed for a long time, a large torque will be generated, which causes the locking bolt to wear and cause the locking bolt to loosen and fall off, thereby affecting the stability of the connection between the impeller and the drive shaft during long-term use.
