[0025] An axially flexible gear oil pump according to an embodiment of the utility model will be described in detail below with reference to the accompanying drawings.

[0028] The axial flexible transmission component includes a first connecting seat 301, a second connecting seat 302, a plurality of fixed grooves 303, a plurality of flexible steel belts 304, a fixing frame 305 and a driving motor 306.

The flexible steel belt 304 is made of spring steel.

[0029] It should be noted that by setting up the first connecting seat 301 and the second connecting seat 302, and opening a fixing groove 303 at one end of the first connecting seat 301 and the second connecting seat 302, the flexible steel belt 304 set between the first connecting seat 301 and the second connecting seat 302 can be fixed more stably. During transmission, the rotating shaft of the driving motor 306 is flexibly connected to the gear shaft 2 of the gear inside the pump body 1 by using the first connecting seat 301, the second connecting seat 302 and the flexible steel belt 304.
