详解导致球磨机齿轮折断的原因

齿圈跳动引发折断

由于球磨机的大齿圈是用螺栓固定在简体上的，其端面跳动是靠分布在大齿圈圆周上的螺丝孔用顶丝调整。当大齿圈端面跳动量没达到要求，球磨机在长时间运转后，螺栓松动，齿圈变形，就容易造成齿圈振动。

机身振动导致

球磨机在运转时，出现频繁的振动，如果不及时处理，则坐导致延伸轴轴承座松动引起小齿轮振动，如果齿轮轴与延伸轴不对中，齿轮轴中心线与延伸轴倾斜偏差较大，引起正在运转齿轮发折断现象。

安装因素

球磨机小齿轮与大齿圈的啮合非常关键，合理的安装可以延长球磨机大小齿轮的使用寿命，但是当大小齿轮安装时，大齿圈已经随筒体固定，便需要我们调整小齿轮的位置，要求小齿轮与大齿圈轴向中心线平行，齿顶间隙与齿侧间隙合适，过小容易发生根切现象，过大齿轮易发生断齿现象。

未盘车或盘车时间不够

停机之前必须停止向磨机给矿，用水清空球磨机筒内的物料，不然粘稠的料浆干涸后会粘在球磨机简内，增加下次启动球磨机的负荷，即使这样，在下次启动球磨机之前仍然需先启动慢速驱动装置进行盘车，这样不仅会让球磨机主轴承与中空轴中间形成一层油膜，也使磨机内的钢球物料松散。这样在启动磨机时，可以大大减少启动负荷。如果球磨机在启动之前不进行盘车的话，球磨机一旦进行启动时会容易导致小齿轮断齿。

Vending Ice Cream Machine

Commercial ice cream vending machines can cash accept, |coin operated, credit and debit cards, membership cards and mobile wallets in conjunction with existing coin-operated machines. Customers can use a credit or debit card to draw a magnetic stripe card, click on a contactless RFID card, or use NFC or mobile wallets to pay, such as Apply Pay, Google Wallet, or Softcard. In addition to credit card payment through the app, you can also recharge cash through the charger installed by Termina. Of course, the cashless ice cream Vending Machine can make the cashless operation by scanning the QR code.

In order to adapt to our cashless society, we can use debit or credit cards instead of cash to increase the value of automata.

According to Reuters, banknotes are gradually withdrawn from circulation around the world to reduce the spread of the virus. Therefore, cashless ic
