Description
技术领域
本技术方案涉及机匣端面的密封，特别涉及一种包括金属密封垫的端面密封结构。
背景技术
在传统附件传动系统结构中，机匣壳体端面密封是常见的密封结构，机匣壳体端面密封性能至关重要。机匣壳体端面密封一般为耐油石棉橡胶垫上涂抹“乐泰587”密封胶后，装配于机匣壳体结合面上的方式，耐油石棉橡胶垫弹性差，压紧力不均匀，可能会导致附件机匣偏斜，从而引起齿轮偏斜等问题，而且石棉密封垫更换频繁，报废率高。因此密封可靠性稍差，使用成本高。
发明内容
本发明解决的技术问题：提供一种密封可靠性高、寿命长的机匣端面密封结构。
本发明的技术方案：一种机匣端面密封结构，所述的结构包括前壳体、后壳体和金属密封垫，金属密封垫被压紧在前壳体和后壳体的对接端面上；所述金属密封垫的两侧端面上开有凹槽；所述凹槽内开有贯通两侧凹槽的通孔；所述凹槽和通孔内硫化有橡胶。该设计，通过增加了金属密封垫提高了密封寿命和装配效率。同时优化的密封垫结构，结构形式简单，密封可靠性高。
优选地，金属密封垫上的结合面上全部设置有凹槽。该设计保证了所有端面接触部位都能实现密封。
优选地，所述的金属密封垫为铝合金材料，该设计便于加工，材料成本低。
优选地，所述的金属密封垫厚度为2-4mm。该设计一方面充分考虑了密封的可靠性，另一方面最大限度减低了结构的质量。
优选地，所述的橡胶材料为氟橡胶，该设计密封效果好，材料成本低。
附图说明
图1为机匣端面装配结构示意图；
图2为金属密封垫骨架结构示意图。
具体实施方式
如图1所示，所述的结构包括前壳体1、后壳体2和金属密封垫3，金属密封垫3被压紧在前壳体1和后壳体2的对接端面上。如图2所示，所述的金属密封垫3由金属骨架33和橡胶组成，该结构利用一种将橡胶硫化到金属骨架33胶圈槽31的设计方法。金属骨架33材料选择质量轻、易加工的铝合金2A12,骨架厚度为3mm，公差为±0.03，骨架正反两面分别为深度1mm的胶圈槽。同时金属骨架33的胶圈槽31上分布着59处φ1.8通孔32，硫化的橡胶通过这些孔，将正反两面的硫化胶圈固定到金属骨架上。橡胶材料为氟橡胶FX-4。与金属密封垫相配零件为前、后两个壳体，壳体材料均为铸镁(ZM6)，前、后壳体与金属密封垫接触的端面的表面粗糙度为1.6um。该金属密封垫工作密封介质为滑油4106；工作温度范围为-55℃～+120℃；工作压力为50kPa，密封检查压力0.1～0.15MPa。该结构不需要在机匣壳体上加工胶圈槽，提高机匣加工工艺性。
