中国经济的持续发展和民航机队的不断扩大使得中国航空维修业得到了空前的发展。国内航空维修企业已经开始从劳动资本密集型向技术资本密集型调整,标志之一是不断拓展发动机和辅助动力系统(APU)的深度维修能力。发动机和AP[U的主轴轴承及其配套的传动系统轴承是维修中的关键零部件,以往其检测、维修和更换都需依靠国外承修商和OEM制造商,严重影响了维修企业的成本和效率。在国内开展符合适航要求的轴承检测业务,可以大大提高轴承使用效率,减少维修企业轴承库存 The continuous development of China’s economy and the continuous expansion of civil aviation fleet have given China’s aviation maintenance industry unprecedented development. Domestic aviation maintenance companies have begun to shift from labor-intensive to technology-intensive capitalization, one of the hallmarks of which is the continuous expansion of the in-depth maintenance capabilities of engines and auxiliary power systems (APUs). Engine and AP [U’s spindle bearings and their drivetrain system bearings are the key components for maintenance. In the past, their testing, repair and replacement required reliance on foreign contractors and OEM manufacturers, which seriously affected the cost of repairing the enterprise. effectiveness. In the country to meet the requirements of airworthiness of the bearing testing business, can greatly improve the efficiency of the use of bearings and reduce maintenance of enterprise bearing inventory
