平地机出厂前,已调整好回转圈齿与蜗轮箱齿之间的间隙。但工作一段时间后,由于回转圈齿磨损等原因,回转圈与蜗轮箱的配合间隙就会变大,进而加剧回转圈的磨损,降低回转圈的使用寿命。此时必须将间隙调整到规定值。 Grader before leaving the factory, has been adjusted to revolve the ring gear and worm gear box between the gap. However, after working for a period of time, due to the wear of the rotating ring gear and other reasons, the cooperation gap between the rotating ring and the worm gear box becomes larger, which further aggravates the wear of the rotating ring and reduces the service life of the rotating ring. In this case, the clearance must be adjusted to the specified value.
