4.半年检查与维护 除包括月检查内容外还应有: (1)检查所有的减速器的齿轮啮合和磨损情况,齿面点蚀损坏不应超过啮合面的30%,且深度不超过原齿厚的10%(固定弦齿厚);齿轮的齿厚磨损量与原齿厚的百分比不得超过表9的规定值;检查轴承的状态;更换润滑油。 4. Six months of inspection and maintenance, in addition to including the monthly inspection should be: (1) check all gear meshing and wear, tooth pitting damage should not exceed 30% of the mating surface, and the depth of no more than the original Tooth thickness of 10% (fixed chord thickness); Gear tooth thickness wear and the percentage of the original tooth thickness shall not exceed the value specified in Table 9; Check the bearing status; Change the lubricating oil.
