The beneficial effects of the utility model are：
Chain Wheel of Flight Bar Conveyor axle group left sprocket wheel, right sprocket wheel and rotary shaft provided by the utility model are the one of monoblock cast
Body structure, this structure reduce the cooperation and processing between sprocket wheel and rotary shaft, have saved processing and manufacturing cost；Axle sleeve and transparent cover
Between and bearing block and rotary shaft between be provided with the first sealing ring, the second sealing is provided between transparent cover and bearing block
Circle, compared with sprocket shaft group structure of the prior art, the utility model reduces the arrangement of sealing, so as to reduce lubricating oil
The probability of leakage；Rotating shaft terminal is projected with spline, and left axle bearing assembly is identical with right bearing modular construction and is symmetrical arranged, because
The protective cover of sprocket shaft group one end, when working face changes face, need to only be arranged on the other end of sprocket shaft group, so as to subtract by this
The labor intensity of dismounting is lacked.
