Description

Technical Field

[0002] Chain drive is a transmission method that transmits the motion and power of a driving sprocket with a special tooth shape to a driven sprocket with a special tooth shape through a chain. Chain drive has many advantages. Compared with belt drive, it has no elastic sliding and slipping, accurate average transmission ratio, reliable operation and high efficiency; it has large power transmission, strong overload capacity and small transmission size under the same working conditions; it requires small tension and small pressure on the shaft; it can work in harsh environments such as high temperature, humidity, dust and pollution. In existing textile machines, the power transmission chain is generally equipped with a protective cover on the outside, while the protective cover currently used only covers the transmission chain and isolates the transmission chain from the outside world;

[0003] After long-term use of the chain and sprocket, the lubricating oil on them becomes dry. In order to reduce wear, lubrication needs to be added. The traditional oiling method requires removing the entire transmission chain cover and then slowly applying oil. This operation is obviously more troublesome.
