Mechanical chain manufacturers introduce many types of chains, which can be divided into transmission chains, transport chains, decoration chains, cable-tightening chains and special chains according to their uses. According to the structure of the chain: it can be divided into roller chain, sleeve chain, plate chain, nylon roller chain, scraper chain, sleeve chain and so on.
Most chains are composed of chain plates, chain pins, shaft sleeves and other components. Other types of chains only make different changes to the chain plates according to different needs. Some are equipped with scrapers on the chain plates, some are equipped with guide bearings on the chain plates, and some are equipped with rollers on the chain plates. These are all intermittent modifications to be used in different applications.
For ordinary chains, the smooth parts are mainly the sprocket and the rollers of the chain, the chain shaft and the bushing. Due to the different structure of the chain, the smooth part of the chain may also be changed. However, in most chains, the smooth parts are still the sprocket and the rollers of the chain, the chain shaft and the bushing.
Since the cooperation gap between the shaft of the chain and the shaft sleeve is small, it is difficult to smooth. Regarding special chains: such as chains equipped with bearings, rollers, and other conflict pairs, consider the smooth parts of these friction pairs.
The primary failure method of the chain: A: pin cracking, B: pitch increase, C: sprocket tooth cracking, D: chain jamming
Smooth oil should be selected as much as possible. For special chains and special circumstances, smooth grease and dry film smoothing agent can be selected. In response to the maximum satisfaction of the chain's request for smoothing agent when working, and the requirements of equipment and consumption, choose suitable and economical smoothing agent.
