Pengetatan torsi vs beban klem

Nilai Awal yang Disarankan

Perkiraan perhitungan torsi di bawah ini hanya ditawarkan sebagai panduan. Penggunaan kontennya oleh siapa pun adalah tanggung jawab orang tersebut dan mereka menanggung semua risiko.

 

Karena banyak variabel yang mempengaruhi hubungan torsi-ketegangan seperti kesalahan manusia, tekstur permukaan, dan pelumasan, satu-satunya cara untuk menentukan torsi yang benar adalah melalui eksperimen di bawah kondisi sambungan dan rakitan yang sebenarnya..
