Furthermore, a dust guard is arranged above the lower bearing.
Furthermore, the dust guard is the ring board with dispersion axle complex, and the peripheral diameter of dust guard is not less than the peripheral diameter of lower bearing.
Furthermore, the upper bearing is a separable bearing, so that the dispersion shaft is convenient to disassemble.
Furthermore, the joint surface of the upper labyrinth sleeve and the lower labyrinth sleeve is provided with a plurality of concave-convex parts which are matched with each other.
Furthermore, the joint surface of the upper labyrinth sleeve and the lower labyrinth sleeve is provided with three concave-convex parts which are matched with each other.
The utility model has the advantages as follows:
1. the synchronous belt is positioned between the upper bearing and the lower bearing of the dispersion shaft, so that the bearing stress is uniformly dispersed, and the bearing is more durable.
2. The labyrinth sleeve is additionally arranged below the polytetrafluoroethylene oil seal of the lower bearing, so that slurry can be effectively prevented from climbing into the oil seal and the bearing, the dust guard is additionally arranged above the lower bearing, dust is prevented from falling into the bearing, and the bearing is prevented from being worn and lost due to slurry or dust.
