There is gap, it is ensured that gear rotor 18 rotates smooth.For existing assembly technology, if sealing gear pump cover plate 17
Using cold-pressing assembly on base 22, its cold pressing pressure is used as core parameter, if pressure is not enough, seal cover board 17
Become big with the axial gap between gear rotor 18, reveal increase, cause the gear efficiency of pump to reduce；If pressure is too big,
The pressure that seal cover board 17 is acted on base 22 is too big, causes base 22 to deform, and seal cover board 17 may be with
Gear rotor 18 is contacted, gear pump seizure；In addition, needing to ensure sealing in the cold pressure procedure of seal cover board 17
The good depth of parallelism between 22 mounting surface of cover plate 17 and base, if seal cover board 17 is inclined, seal cover board 17 is still
When not colding pressing in place, 17 bottom of seal cover board may be contacted with 18 upper surface of gear rotor, also result in gear
Pump seizure.For riveting process is equally also required to control riveting pressure, and there is the gear pump of feature of present invention, one
Aspect reduces the part of additional designs thrust structure by compressor shaft tying selection structure is moved on gear pump
Processing and assembly cost；Meanwhile, the lower thrust of shafting is converted into into the axial direction between seal cover board 17 and base 22
Sealing force, reduces the extra assembly technology of seal cover board 17.As shown in figure 4, the wearing layer of seal cover board 17
The lower thrust under shafting action of gravity is born on 171, will be seal cover board 17 tight in the presence of shafting lower thrust
Tightly it is fitted on base 22, the axial limiting of shaft is realized by base 22, while 17 lower end of seal cover board
The axial gap (oil film seal thickness) for designing is maintained between 18 upper surface of face and gear rotor, it is ensured that good axle
To sealing function.Compared to cold pressing pressure, the gravity of drive shaft shafting is less, and base 22 will not be deformed,
The quality of fit of gear rotor 18 and the installation site of Oil pump cylinder 26 is not interfered with.
Further, to prevent 17 rotation of seal cover board, arrange limited between base 22 and seal cover board 17
The position limiting structure that seal cover board processed 17 is rotated.For example, setting is radially protruded in the periphery of seal cover board 17
Have raised 173, the relevant position of base 22 is provided with groove 221, raised 173 are coordinated so as to realize with groove 221
Seal cover board 17 it is spacing.
The oil suction through hole 222 for axially extending is provided with base 22, gear pump is formed by oil suction through hole 222
Suction passage, the lubricating oil in oil sump 20 is sucked the oil suction intracavity of gear pump by oil suction through hole 222.Base
Oil scupper 223 is provided with 22 upper surface, oil scupper 223 can connect accommodating chamber 16 and main oil-hole 41, make
During proper gear pump oil extraction, lubricating oil Jing oil scuppers 223 enter main oil-hole 41.
Connection through hole 224 is provided with base 22, is along the circumferential direction uniform three in the present embodiment, even
The one end for connecting hole 224 is connected with groove structure 172, and the other end is connected with the oil sump 20 of compression motor spindle, is passed through
Lubricating oil is discharged by connection through hole 224 in time, formed at the supplementary bearing 19 and seal cover board 17 circulation fuel feeding and
Oil extraction is circulated, and prevents impact supplementary bearing in the space that lubricating oil is gathered between lower support base 6 and supplementary bearing 19 always
19 and the lubricant effect of 17 upper end surface of seal cover board.
