The plate chain consists only of the chain plates and the pins.
The chain plates are connected by pins to withstand the tension experienced by the chain plates.
The outer chain plate and the pin are an interference fit, and the pin is riveted.
The inner chain plate, the middle chain plate and the pin are sliding fits.
Through the chain plate, the pin is subjected to shearing force,and at the same time, the inner surface of the inner chain plate of the inner chain plate slides when the chain is bent.
Interference fit When the hole is assembled with the shaft, the tolerance of the hole is below the tolerance band of the shaft.(The algebraic difference obtained by subtracting the size of the hole from the size of the matching shaft. If the difference is negative, it is interference.)
Clearance fit When the hole is assembled with the shaft, there is a fit of the gap (including the minimum gap equal to zero).
At this point, the tolerance of the hole is above the tolerance band of the shaft.
