The structure of the combine chains(GETECHAIN) https://www.getechain.com/ : The combine chains are divided into chain product series according to the basic structure of the component chain, i.e. the shape of the components, the parts and parts engaged with the chain, the size proportion among the parts, etc. There are many kinds of chains, but their basic structures are only the following, and the others are all variations of these kinds. We can see from the above chain structures that most chains are composed of chain plates, chain pins, shaft sleeves, and other components. Combine chains usage: When drawing the steel pipe, the entire inner link plate enters the gap position between the two teeth of the pentagonal wheel. When the driving wheel rotates in the W direction, the A end of the inner link plate firstly meshes with one tooth of the five-angle wheel, and then the other tooth of the five-angle wheel meshes with the B end of the inner link plate, and the five-angle wheel pushes the B end of the inner link plate forward under heavy load. Since the rotation angle between the hole at the B end of the inner link plate and the pin shaft is larger than that at the A end when drawing the steel pipe, the hole wear at one end of the inner link plate is much faster than that at the other end under unidirectional gravity transmission. When a new inner link plate is put into use and the B end is broken, the hole wear at the A end is only about 5 mm to 8 mm .. If it continues to be used, fatigue fracture will occur soon in the B-end hole. If it is turned around at this time (the A and B ends are opposite to each other), the service life of the inner link plate can be prolonged. The results show that it is feasible to use the combine chains turning. Selection of lubricating materials for combine chains: In order to reduce friction and wear between friction pairs and reduce friction resistance, all wear-reducing substances can be used as lubricating materials. There are many kinds of lubricating oil, grease, solid lubricant, etc. When selecting a lubricant for chain transmission, the coordination among lubrication form, ambient temperature, and chain specifications must be considered. Generally, high-quality mineral oil with stable chemical properties is used, and the one with pure composition, no oxidation and no impurities is the best.
