2020년 6월 이후 헥사곤 WN5(Involute Splines ISO 4156 and ANSI B92.2M)을 구입 또는 버전업데이트한 고객은 아래처럼 버전 확인하여 V5.1 이면 V5.2 무료 버전업데이트를 당사에 요청하시기 바랍니다: ( WN5 실행 -> 상단에 버전 확인, 또는, Help -> WN5 에서 버전확인! )
WN5 V5.1 에서 다음과 같이 에러가 발견되어 헥사곤 정책에 따라 V5.2로 무료버전 업데이트를 진행합니다: (아래설명 참조!)
New in WN5 V5.1 was a Quick4 view in an A3 drawing frame.
Unfortunately, the table according to ANSI B92.2M has been displayed since then, even though ISO 4156 was selected.
And if ANSI B92.2M was selected, the dimension of the tooth thickness “Max effective” of the splined shaft was always displayed for H / h, although according to ANSI B92.2M there are also the pairings H / d, H / e, H / f.
Affected customers with WN5 V5.1 receive a free update.
In the latest ISO 4156: 2021 (also already in ISO 4156: 2005) there are also the transition fits H7 / js and H / k for a tight fit.
When calculating the dimensions of “js” and “k” for esv (fundamental deviation) not the ISO 286 dimensions according to the fit table, but the special cases “esv = (T + lambda) / 2” for “js” and “esv = (T + lambda)” for “k”.
In version 5.1 and older versions of WN5, the dimensions according to ISO 286 were used.
The new calculation method makes the joints H / js and H / k significantly tighter.
