涡轮盘是发动机重要承力构件,在转速高、温度高的环境下工作,涡轮盘具有较高的抗疲劳、抗高温氧化及抗燃气腐蚀能力。涡轮盘沿圆周均布一般在60-102个榫槽,叶片用枞树形榫头插入盘的枞树形槽内,检测榫槽的尺寸、位置度技术条件要求,保证叶片传递载荷分布均匀,提高发动机的性能稳定性。
Turbine disk is an important engine bearing components, high speed, high temperature environment, the turbine disk has high resistance to fatigue, high temperature oxidation and resistance to gas corrosion. Turbine disk along the circumference of the general distribution in the 60-102 tenon slots, the blade with fir tenon inserted into the disk fir-shaped groove, the detection of tongue and groove size, location requirements of technical conditions to ensure that the blade transmission load distribution, improve Engine performance stability.
