There are two series of A and B in the chain number. The A series is the size specification that conforms to the American chain standard: the B series is the size specification that meets the European (mainly the UK) chain standard. Except for the same pitch, they have their own characteristics in other aspects. The main differences are:
1) The thickness of the inner chain plate and the outer chain plate of the A series products is equal, and the equal strength effect of the static strength is obtained through different adjustments. The inner chain plate and the outer chain plate of the B series products are adjusted to be equal, and the equal strength effect of the static strength is obtained through different Baidu.
2) The main dimensions of each component of the A series have a certain ratio to the pitch. Such as: pin diameter = (5/16) P, roller diameter = (5/8) P, chain plate thickness = (1/8) P (P is the chain pitch), etc. However, there is no obvious ratio between the main size and pitch of the B series parts.
3) Comparing the breaking load value of the chains of the same grade, except that the 12B specification of the B series is lower than that of the A series, the rest of the specifications are the same as the A series products of the same grade.
The product standard is equivalent to the international standard ISO9606:1994, and its product specification, size and tensile load value are completely consistent with the international standard.
Structural features: The chain is composed of inner chain plates, rollers and sleeves, which are alternately hinged with outer chain links, which are composed of outer chain plates and pin shafts.
For product selection, the required chain specification can be selected according to the power curve. If selected according to calculation, the safety factor should be greater than 3.
