Drum dryer in the installation of the wheel belt, the wheel belt and the cylinder body is not installed correctly, that is, the coaxiality of the wheel belt and the cylinder body as well as the parallelism of the two wheel belts did not meet the design requirements of the error control requirements. Solution: pay attention to the installation quality of the wheel belt, strict control: wheel belt and cylinder coaxial deviation within 1mm; two wheel belt parallelism deviation within 1.5mm.
Seat installation, adjustment is not in place: because the bearing seat is not installed in place, will cause the wheel is not horizontal and four wheel height inconsistency. Solution: adjust the bearing seat, so that the wheel line should be installed parallel to the cylinder line, parallelism tolerance control in 0.1mm/m; the height of the same set of wheel bearing seat should be equal, the deviation shall not exceed 0.1mm.
