一种应用于减速器密封修复的轴套加工工艺设计

Design of a Shaft Sleeve Processing Technology for Sealing Repair of Reducers

减速器普遍应用于机械传动系统中,其密封失效是导致在线使用寿命短、机械故障的主要原因。减速器输入、输出轴的密封结构通常采用骨架油封形式,由于输入输出轴的旋转运动造成骨架油封及轴径结合处的相对磨损,唇封与轴径配合部位接触压力降低,最终导致油品泄露损失。减速器的密封修复作业一般通过线下装配实现,设备拆装检修工作量大。为提高减速器装配密封效果及在线使用寿命,设计一种用于易于快速拆装的减速器密封修复用轴套制作工艺,应用于减速器的密封修复。

Reducers are widely used in mechanical transmission systems,and their sealing failure is the main cause of short on-line service life and mechanical failures.The sealing structure of the input and output shafts of the reducer usually adopts the form of a skeleton oil seal.Due to the rotational motion of the input and output shafts,the relative wear of the skeleton oil seal and the joint of the shaft diameter is caused,and the contact pressure between the lip seal and the joint of the shaft diameter is reduced,ultimately leading to oil leakage and loss.The sealing repair operation of reducers is generally achieved through of-fline assembly,and the workload of equipment disassembly and maintenance is large.To improve the sealing effect and online service life of reducer assembly,a shaft sleeve manufacturing process for easy and quick disassembly and repair of reducer seals is designed and applied to the sealing repair of reducers.
