Qingdao chain factory

　　Qingdao motorcycle chain manufacturer of small make up to tell you the length of the chain

　　The number to link chain length. Even number off for best link, so that the chain stitch when ring is inside the outer chain plate and chain plate, can use spring clip or split pin lock joint. If the link with odd number, need to adopt the transition link. Link in the chain tension, transition must bear the additional bending load, usually should avoid to use.

　　Tooth shape chain composed of a lot of stamping of tooth shape chain board with hinge join together, in order to avoid when the mesh chain, the chain should guide plates (divided into afferent and efferent). Both sides of the tooth shape chain board is straight, chain plate while working side engages with sprocket tooth profile. Hinge but make it sliding vice or rolling roller type can reduce the friction and wear, good effect is shell. Compared with the roller chain, tooth shape chain smooth running, low noise, high ability to withstand the shock load; But the complex structure, more expensive and also heavier, so its roller chain did not widely applied. Chain of tooth shape chain more used in high speed (speed up to 40 m/s), or movement to demand higher transmission precision.

　　National standards only stipulated the roller chain sprocket tooth the tooth surface of arc radius, tooth groove arc radius and tooth groove Angle of maximum and minimum values (see GB1244-85). The actual tooth face of various sprockets shall be between the maximum and minimum tooth shape. Such processing make sprocket tooth profile curve design has a lot of flexibility. But tooth should guarantee the chain energy saving mesh smooth entry and exit freely, and to facilitate processing. Meet above requirement of end face a variety of tooth profile curve. The most commonly used tooth profile is "three circular arc line", which is to end tooth form by three circular arc () () and a straight line.
