Roller chain: Do not directly immerse the chain in strong acid and alkaline cleaners such as diesel, gasoline, kerosene, WD-40 and degreasing agent, because once washed, the inner ring bearing of the chain will be filled with high-viscosity oil , It is usually called butter falling off, the inner ring will become dry, no matter how much low-viscosity chain oil is added later, it is useless.
You can also use hot soapy water, hand sanitizer, disposable toothbrushes or slightly harder toothbrushes. Rinse directly with water. The cleaning effect is not good. Dry it after washing, otherwise it will rust. Special chain cleaners are generally imported products with very good cleaning effect and good lubrication effect. They are sold in professional stores, but the price is more expensive, and Taobao also sells them. Friends with a better economic foundation can consider them.
For metal powder, find a larger container, take a spoon, rinse with boiling water, take out the lifting chain, put it in the water, and then clean it with a harder brush.
Advantages: easy to clean the oil on the lifting chain. Usually, the butter in the inner ring is not clean, not irritating, and does not hurt your hands. The master used this substance when washing his hands during mechanical work. This is very good and can be purchased from a larger hardware store.
Disadvantages: Since the additive is water, the lifting chain needs to be cleaned or dried after a long period of cleaning.
Roller chain structure:
The outer chain plate and the pin shaft, the inner chain plate and the sleeve are respectively connected by interference fit. The gap between the sleeve and the pin, and the gap between the sleeve and the roller are matched. When the sprocket teeth are engaged with the chain, the friction between the rollers and the teeth is basically rolling friction. Sliding friction between sleeve and roller, pin and sleeve.
The roller link plate is usually formed in a figure eight shape, so that the strength of each part is close, and the inertia and weight during movement are reduced.
Compared with belt drive, roller chain drive has the characteristics of compact structure, small load acting on the shaft, large carrying capacity, high efficiency and accurate average transmission ratio.
