由于检修工艺不明确和修复设备不具备等原因,静液压马达主轴大量报废,造成检修成本大增。根据ZM732型静液压马达油封装配结构特点,采用一种简单可行的主轴拉伤再利用方案,既能解决了油封漏油问题,又能重复利用拉伤主轴,具有一定的推广应用价值。 As the maintenance process is not clear and repair equipment does not have other reasons, a large number of scrapped hydraulic motor spindle, resulting in significant increase in maintenance costs. According to ZM732 hydrostatic motor oil seal assembly structure characteristics, using a simple and feasible spindle strain re-use program can not only solve the problem of oil seal leakage, but also to recycle the spindle, has a certain value of promotion and application.
