Weld part forms also through the end spinning to supporting part, to increase the fitting area of wheel disc and wheel hub, so as to ensure to weld
Intensity, improve the intensity and stability of whole thrust wheel.
The utility model has the advantages that：
1st, the good sealing effect of whole thrust wheel, stability are high.
2nd, rubber layer set by closure can effectively ensure that sealing effectiveness, while maintenance easy to disassemble.
3rd, the structure of closure is simple, convenient disassembly.
4th, wheel disc is manufactured using spinning, and cost is relatively low, and wearability is good.
5th, the spun portion of wheel disc is distributed in the both sides of supporting part so that the stress of wheel disc and whole thrust wheel is more balanced, keeps away
Exempt to deform, so as to increase the service life.
6th, the binding face of weld part is big, can effectively improve the intensity and resistance to overturning of welding.
