Detailed Description

The magnet structure of the wheel-side speed reducer of the driving axle of the wheel-type excavator is further described in detail below with reference to the accompanying drawings and the specific embodiments.

The magnet structure of the wheel-side speed reducer of the driving axle of the wheel type excavator comprises a hub 1, a tapered roller bearing 2, a supporting shaft 3, an inner gear ring 4, a planet wheel 5, a planet wheel shaft 6, a planet wheel gasket 7, a round nut 8, a planet wheel carrier 9, a combined gasket 10, a plug 11, a bolt 12, a magnet 13 and a magnet rod 14, wherein the magnet structure is shown in the figure 1; the outer ring and the inner ring of the tapered roller bearing 2 are respectively assembled on the hub 1 and the support shaft 3, the inner gear ring 4 positioned at the left side of the tapered roller bearing 2 is assembled on the support shaft 3 and locked by a round nut 8, and the planet wheel 5 and the planet wheel gasket 7 are fixed on the planet wheel carrier 9 through a planet wheel shaft 6; the planet carrier 9 is locked on the hub 1 through bolts 12; the magnets 13 are provided with four magnets which are uniformly distributed and fixed on the magnet rod 14, one end of the magnet rod 14 is fixed on the plug 11, and the other end of the magnet rod extends into gear oil in the hub 1; the combined washer 10 and the plug 11 are locked on the planet carrier 9 to play a role in sealing the hub 1.
