DongSheng is specialized in producing all kinds of standard and non-standard chains, e.g. A or B series chains, automobile chains, stainless steel chains, combine harvester chains, heavy-duty cranked link transmission chains, stereo garage chains and maintenance-free chains etc.
roller chain structure
>Plate
The plate bears the tension placed on the chain. Usually this is a repetitive load, but
sometimes it is accompanied by shock. Therefore, the plate must have not only great static
tensile strength, but also must hold up to the dynamic forces of load and shock.
>Connecting Pin
The pin is subject to shearing and bending forces transmitted by the plate. At the same time, it
forms a load-bearing part, together with the bush, when the chain flexes during sprocket
engagement. Therefore, the pin needs high tensile and shear strength, resistance to bending,
and sufficient endurance against shock and wear.
>Bush
The bush is subject to complex forces from all parts, especially from the repetition of shock
loads when the chain engages the sprocket. Therefore, the bush needs extremely high shock
resistance. In addition, the bush forms a load-bearing part together with the pin, and as such
requires great wear resistance.
>Roller
The roller is subject to impact load as it strikes the sprocket teeth during chain engagement
with the sprocket. After engagement, the roller changes its point of contact and balance. It is
held between the sprocket teeth and bush, and moves on the tooth face while receiving a
compression load. Therefore, it must be resistant to wear and still have strength against
shock, fatigue and compression.
