I类隔爆型电气设备螺纹紧固件的设计

Design of Thread Fastener of I-style Flameproof Electrical Apparatus

通过对螺纹紧固件的受力、工作载荷、许用应力、刚性系数、预紧系数及预紧力等五方面的分析,为I类隔爆型电气设备螺纹紧固件的设计提供了依据。

Analyzing the 5 aspects of thread fastener： under stress,working load, permissible stress, factor of rigidity, factor of pretightening and pretightening force, to provide basis for design of thread fastener of Ⅰ type flameproof electrical apparatus.
