这样，在螺栓张力相同的情况下，缩小后的窄光滑面的压紧应力就会增大。
So, in the same bolt tension narrow narrow smooth after the pressure stress increases.
在这种场合，金属垫片也不适用，因为这时要求的压紧力过大，导致螺栓较大的变形，使法兰不易封严。
In such cases, a metal gasket also not applicable, because the requirements of the compaction force is too large, caused the bolts, make much deformation flange is not easy to seal.
当气缸垫装在气缸体上，然后装上气缸盖以后，气缸盖螺栓就压紧软金属垫，这样结合处就完全密封了。
When the gasket is placed on the block and the head installed, tightening of the head bolts squeezes the soft metal so that the joint is effectively sealed.
这样，在螺栓张力相同的情况下，缩小后的窄光滑面的压紧应力就会增大。
Thus, under the same bolt tension, reduce narrow smooth surface after the compressive stress will increase.
在这种场合，金属垫片也不适用，因为这时要求的压紧力过大，导致螺栓较大的变形，使法兰不易封严。
In such cases, the metal gasket does not apply, because then the pressing force required is too large, resulting in greater deformation of bolts, so difficult to seal flange.
本实用新型的连接为面接触，通过螺栓形成的压紧力大，防电晕，可靠性高。
The connection of the clamp is surface contact; and the clamp has large compaction force formed by bolts and high reliability, and is anti-corona.
检查所有基础上的螺母和压紧装置的螺栓是否松动。3.2安装规定每三月把齿轮箱的油更换一次。
1 check all the nuts and bolts compaction device on the basis of whether is loose. 3.2 installation regulations every march the gearbox oil replacement.
连接时本发明特殊结构，箱与箱的压紧力比原螺栓拧紧力增大2.5倍，因此连接强度很大，有利于运输的安全。
Comparing prior art, the invention increases packing force 2.5 times. Large bonding strength is in favor of safety of transportation.
螺栓预紧力的大小对垫片压紧应力的大小及分布有重要影响。
The bolt preloading also has important influence on the distributions of compressive stresses of the two gaskets.
内压加大时，刚度小的螺栓将加速垫片压紧应力的降低，对紧密性不利。
The bolt with lower stiffness accelerates the decrease of compressive stress in gasket during pressure loading, which is harmful to joint tightness.
内压加大时，刚度小的螺栓将加速垫片压紧应力的降低，对紧密性不利。
The bolt with lower stiffness accelerates the decrease of compressive stress in gasket during pressure loading, which is harmful to joint tightness.
