Description

Technical Field

[0001] The utility model relates to the field of turbine heads, in particular to a turbine head which is convenient for oil injection. Background Art

[0002] The turbine head is a key component in the turbocharger. It is located in the exhaust duct. Its main function is to use the exhaust gas discharged by the engine as power to drive the turbine in the turbine chamber to rotate. In this process, the turbine and the impeller are coaxial. The impeller is located at the intake end. When the turbine rotates, it will drive the impeller to rotate together, thereby compressing the air at the intake end, increasing the engine's intake volume, and improving the engine's efficiency and power output.

[0003] After searching, the application number is "202220331879.8", which provides a turbine head that is easy to oil fill. When the device is in use, the grease in the outer casing is replaced. First, the oil filling hole is opened by the oil filling bolt, and the second handle is manually rotated to drive the threaded rod to rotate. The rotation of the threaded rod drives the threaded slider to slide upward in the limiting slide groove. When the threaded slider slides upward, the pressure in the outer casing increases, and the waste grease is accelerated to be discharged from the oil filling hole under the action of pressure. After the waste grease is discharged, the second handle is manually turned to drive the threaded rod to rotate in the opposite direction, and the threaded rod drives the threaded slider to slide downward in the limiting slide groove, and then new grease is added to the outer casing through the oil filling hole.

[0004] The above-mentioned rotation and threaded rod, under the action of air pressure, make the lubricating oil in the casing be quickly discharged. However, when this structure is in use, the pressure hole set is open. When the turbine is rotated, oil and metal debris (produced by turbine wear) in the turbine may enter the pressure hole, causing the pressure hole to be blocked, thereby reducing the smoothness of the lubricating oil discharge.
