The utility model discloses a multi-piece overlapped type lubricating pinion which comprises a plurality of gear pieces, and the gear pieces are overlapped to form a gear. When the two opposite gear pieces are attached and stacked, the two oil grooves form a closed oil channel, each gear tooth corresponds to two oil channels, and the two oil channels penetrate through different tooth surfaces of the gear tooth respectively. The gear sheet is provided with bulges at oil outlets of the oil channels; the outer wall of the shaft tube is in smooth fit and rotary fit with the circular through hole of the gear sheet; an oil cavity and an oil hole penetrating through the oil cavity are formed in the center of the shaft tube along the central axis, and when the shaft tube is sleeved with the gear piece, the oil hole corresponds to the oil channel oil inlet in position. The pinion composed of the gear pieces is not directly attached to the gear to be lubricated through the tooth surface, lubricating grease flows out through the protrusions and then is guided to flow towards the two sides of the gear to be lubricated in the thickness direction, and the lubricating gear is fully covered. When the difference is small, the gear gaskets are thin, and the thickness specification can be finely adjusted by adjusting the number of the gear gaskets.

The invention relates to a method (100) for operating a system (200) for converting energy. The proposed method (100) comprises: operating (101) an energy converter (205) of the system (200) by extracting liquid hydrogen from at least one hydrogen tank (203) of a hydrogen tank system (201) for storing hydrogen; determining (103) an expected shutdown point in time of the energy converter (205); starting from a switching point in time before the expected shutdown point in time, operating (105) the energy converter (205) by extracting gaseous hydrogen from the at least one hydrogen tank (203) in order to vaporize liquid hydrogen accumulated in an evaporator (217) of the hydrogen tank system.

The present invention relates to a urine collection device, in particular to a stackable liquid collector and a matching structure of the liquid collector and a test tube assembly. The matching structure of a liquid collector and a test tube assembly of the present invention, the lower part of the liquid collector matches with the opening of the test tube assembly; the annular side wall A of the liquid collector and the bottom plate enclose a liquid collecting portion with an opening facing upward, and the bottom plate is provided with a liquid guide hole; the side wall C located below the bottom plate and on the periphery of the liquid guide hole is inserted into the opening of the test tube assembly and matches with the test tube assembly; the side wall B is located on the inner side of the side wall C, and the side wall B, the side wall C and the bottom plate together form a groove. Another subject of the present invention is a liquid collector. The present invention has the advantages of being stackable, smooth liquid conduction, low cost, and high production efficiency and yield rate.
