Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment for being obtained, belongs to the scope of the utility model protection.
Fig. 1-5 are referred to, the utility model provides a kind of technical scheme：A kind of needle bearing hold-down support structure, including
Needle bearing body 1 and hold-down support 6, the outer ring of needle bearing body 1 are provided with outer collar 4, and the internal package of outer collar 4 has rolling
Kinetoplast 2, needle bearing body 1 is fixed on inside bearing lock chamber 14, and the correspondence of greasing hole 11 and roller holder 3 and overcoat
Gap between circle 4, while lower bearing protection structure 7 and hold-down support 6 are to be integrally cast, rolling element 2 is by rolling
Body retainer 3 is fixed, and rolling element 2 is internally provided with inside race 5, and rolling element 2, outer collar 4 and inside race 5 are high-carbon
