Balancing machines are widely used in modern machinery, and the choice of lubrication method is also very important. Traditional lubrication methods generally use oil lubrication, but during the unweighting process, chips are easily dropped and stuck in the bearings, which affects the accuracy of unweighting balance.
If the balancing machine bearings use micro-lubrication, this problem can be effectively solved, and many benefits can be obtained:
1. Using micro-lubrication can reduce oil consumption, saving energy and protecting the environment;
2. The operating cost of the micro-lubrication system is very low, it is powered by compressed air, and the energy consumption is low;
3. It can reduce problems such as damage caused by chips getting stuck between the bearings and the journal when oil lubrication is used;
4. It can provide good lubrication for the drill bit and improve the service life of the drill bit.
Compared with traditional lubrication methods, the advantages of micro-lubrication are numerous. To ensure the micro-lubrication effect, the following two points need special attention:
1. Dry and stable air source: The stability of the air source pressure is an important factor for the normal operation of the micro-lubrication device. The power source of the micro-lubrication device is compressed air, so the stability of the compressed air pressure is very important. The moisture in the compressed air will directly affect the atomization effect and thus the lubrication effect, so the stability of the air source pressure and the dryness of the air source are very important.
2. The design of the oil mist output channel size of the balancing machine bearing is very critical, and its rationality directly affects the lubrication effect of the bearing. For the design of the bearing, in practical applications, the design channel of the bearing does not need to be too large, and can generally be calculated according to the size of the journal. Micro-lubrication itself has a very small passage diameter at the lubrication terminal. If the channel is too large, it will lead to insufficient air supply and excessive oil mist output, leading to an impact on the operating environment. Therefore, it should also be fully considered during the design.
