What kinds of joint parts are there for roller chains
The types of joint parts for roller chains are half-mesh, double-pitch half-mesh, spring clamp type, and split pin type. The difference between the half-mesh joint and the ordinary joint is that the joint uses a chain link to connect the inner and outer rings. When the odd number of rings is used, this joint can be used to adjust, but it will affect its strength, so try not to use it. The double-pitch half-mesh joint is a joint with a single-pitch half-mesh joint and an inner ring, which belongs to a joint dedicated to the 25th chain.
Roller Chain spring clip type joints are easy to disassemble and apply to small roller chains. The split pin joint is referred to as a pin-type joint, which is used in the design of large chains.
