注意:只使用刀刃卡尺,以消除未测量完整节距造成错误读数的可能性。
Notes: only use “blade” calipers, in order to eliminate the likelihood of wrong readings resulting from the failure to
measure the complete pitch.
测量伸长(P
在链条的不同区域测量P值,即跨的11个链节的节距。
标准:
链条尺寸
d*t
4x11
5x14
7x20
dn
4
5
7
P max
[毫米]
(英寸)
123.42
(4.859)
157.08
(6.184)
224.4
(8.835)
*注意:根据 ISO 7592,伸长为 2%
Measure the elongation (P)
Measure the P value on different parts of chains, namely the
pitches across 11 chain elements.
Criteria:
Chain dimension:

*Notes: According to ISO 7592, the elongation shall be 2%.
注意:如果超出这些限制,必须立即更换链条。在这种情况下,还应检查链条和链轮的磨损,并且应在必要时
予以更换。
注意:既是只有一个链环存在任何方式的缺陷,必须更换该链条。
Notes: The chains shall be replaced immediately if they go beyond these limits. In this case, it is also necessary to check
the wear of chains and sprockets. The chains and sprockets must be replaced when necessary.
Notes: The chain with any defect in any chain link must be replaced.
注意
不要因为一根负载链条的测量值低于这里给出的更换点就认为它是
安全的。其他因素,如上面目视检查中提到的那些因素也可能导致
链条不安全而需要更换,即使它还远没有达到伸长率更换标准。
