Excavators are inseparable during construction on any site. Construction workers will choose different models of excavators according to the site conditions. For example, in some small construction sites, small excavators are more convenient and maintenance of small excavators Matter, how to maintain its side drive and chain?
1. The side transmission gear is an external open transmission, and the speed is low and the load is large, and it is easy to be contaminated by dust and sludge. Before starting, use an oil can to pour lubricating oil on the gear, and ensure that the dust is removed once a week to extend its working life. Do not apply grease to the side drive gear, because the grease will stick to a large amount of sand and dust, which will accelerate the wear of the gear.
2. In addition, the large gear ring and the driving wheel are fixed by bolts, and need to be inspected and tightened once a week. The drive chain is also used as the final drive component of a small excavator. Its transmission load is very heavy, and it is subject to the impact of driving and braking, and requires careful maintenance.
3. The sleeve roller chain will stretch when working. This is caused by the gap caused by the wear between the sleeve and the roller. Therefore, it is necessary to fill the gap between the chain plates with a thinner lubricating oil. On the slack side of the chain, so that the oil can enter the gap between the chain plates, and then wipe the excess oil with cotton yarn. Do not use butter or high-viscosity oil to lubricate the chain. This will damage the chain and the chain due to the adhesion of sand and dust. Sprocket.
4. If the chain is heavily contaminated, it should be disassembled and cleaned with gasoline, soaked in lubricating oil for half an hour, then taken out to wipe off the excess oil, and continue to be used in the car.
