The utility model proposes a kind of mixing blade assemblies 11.

Fig. 1 to Fig. 3 is please referred to, in an embodiment of the utility model, mixing blade assembly 11 includes mounting base 111, described One end face of mounting base 111 is formed with installation cavity 1111, and offers mounting hole 1113, the mounting hole 1113 in other end It is connected to the installation cavity 1111；

First bearing 112, first bearing 112 are contained in the installation cavity 1111, and abut installation cavity 1111 in circumferential surface Cavity wall；

Cutter shaft 115, cutter shaft 115 are arranged in the bearing hole of first bearing 112, and are pierced by mounting hole 1113；

Collar 117, collar 117 is sheathed on cutter shaft 115, and abuts with the upper end of first bearing 112；And

Stirring blade 119, stirring blade 119 are installed on one end that cutter shaft 115 is pierced by mounting hole 1113；

The cutter shaft 115 also offers the first lockhole 1151 in its radial direction, and the collar 117 is in correspondence first lockhole 1151 position offers the second lockhole 1171, and a locking member connects the first lockhole 1151 and the second lockhole 1171.

In the present embodiment, the substantially umbrella of mounting base 111, the stirring cup assembly 10 of specific shape and food cooking machine 100 It matches, is installed on the bottom of stirring cup assembly 10.111 1 end face of mounting base offers installation cavity 1111, and other end is opened If mounting hole 1113, installation cavity 1111 is connected to for installing cutter shaft 115, and the axis of cutter shaft 115 and installation with mounting hole 1113 The axis of seat 111 coincides, and the rotation of stirring blade 119 can be made more stable, whipping performance is more safe and reliable.To realize cutter shaft 115 effective rotation, in installing first bearing 112 in installation cavity 1111, first bearing 112 is preferably rolling bearing, uses dimension Shield is convenient, and reliable operation, starting performance is good, and bearing capacity is higher under medium speed.The internal diameter and cutter shaft of the first bearing 112 115 outer diameter matches, and the outer diameter of first bearing 112 is matched with the diameter of installation cavity 1111, in order to which cutter shaft 115 can be with Installation is stablized, and installation first bearing 112 makes cutter shaft 115 that can improve the performance of mixing blade assembly 11 with stability of rotation.In addition, When 115 high speed rotation of stirring blade 119 and cutter shaft, the inner ring also high speed rotation of first bearing 112 is driven, outer ring is fixed, interior Lubricating oil is generally required between circle and outer ring to be lubricated, and frictional force is reduced, to enhance the service life of first bearing 112.

Collar 117 is the part being used alone, and is because directly needing larger-diameter original using the shaft shoulder using collar 117 Material, it is economical poor.117 internal diameter of collar is matched with the outer diameter of cutter shaft 115, and the cavity wall of outer diameter and installation cavity 1111 has one Fixed gap.
