饲料粉碎机作为饲料加工机械的常用机械之一，在用户使用过程中常会出现轴承过热、轴承温升过高的现象，温升的高低在一定程度上反映了饲料粉碎机整机的装配质量和用户使用机器的科学合理性。轴承温升过高，会加快轴承磨损，导致主轴的损坏，严重影响整机的可靠性和安全性。影响饲料粉碎机轴承温升的主要因素有：轴承质量、主轴转速、装配质量、润滑以及使用情况。
1 轴承质量
饲料粉碎机用的一般为滚动轴承，轴承材质的优劣对轴承温升有非常重要的影响。劣质材料的轴承装配在饲料粉碎机上，当机器运转时，由于轴承的内圈受力变形，引起支架变形或游隙变化，会使轴承转动不灵活，轴承温升过高。所以，耍保证所购买的饲料粉碎机的轴承是合格产品，最好选择正规厂家生产的饲料粉碎机。
2 主轴转速
饲料粉碎机主轴的转速一股在4500r/min 以上，主轴将电动机的动力传送给转子盘上的锤片或齿爪，饲料粉碎机的工作原理是通过高速运转的锤片或齿爪来击碎饲料完成粉碎工作。轴承作为承载主轴高速运转的部件，其转速越快，轴承温升就越高。所以，在使用饲料粉碎机时，应该按照说明书要求选择配套动力。
3 装配质量
装配质量是影响饲料粉碎机轴承温升的重要因素。轴承盖与轴的配合过紧，或者轴承与主轴的配合过紧或过松都会引起轴承过热。在设备运转中，一旦轴承发出摩擦声响及明显的摆动，应停机拆下轴承，修整摩擦部位，然后按要求重新装配。装配时传动带的松紧程度、转子是否平衡都会影响轴承温升的高低。安装转子的两轴承不同心。即转子轴上安装轴承的两个轴颈位置同轴度不够，转子皮带轮V型槽与动力（电机）皮带轮V型槽未对正，都会使轴承受到不稳定负荷的冲击，从而引起轴承过热。所以，在装配前需要进行转子平衡实验，在饲料粉碎机使用前要检查各紧固螺钉是否松动、调整传送带松紧，特别是齿爪或锤片等高速运转件的紧固必须安全可靠，如开机出现异响，应该马上停机排除故障，以避免轴承和主轴的过早损坏，影响机器的使用寿命。
4 润滑
饲料粉碎机的轴承内润滑油脂过多、过少或老化都容易引起轴承温升过高。若轴承内的润滑油脂过多会产生涡流。出现摩擦增大、轴承散热不良的现象，造成轴承温度急剧升高；润滑油脂过少或使用价廉劣质的润滑油脂，容易造成轴承润滑效果差；轴承内进入杂物，没有及时清理干净会使摩擦增大轴承温升过高。所以在每次使用粉碎机前应检查轴承内的润滑油脂用量是否合适，是否老化变质，并适时添加或更换，粉碎机工作一段时间后应将轴承拆卸并清洗。
5 使用情况
用户使用中引起的轴承温升过高主要原因主要有：喂入饲料过多；喂入量不均匀，造成负荷不稳定；喂入湿度较大的饲料；开机立即进行作业等。所以，喂入饲料时不宜过多、过湿，且喂入量应均匀。饲料粉碎机用的一般为滚动轴承，轴承启动时初期温度相对较高，运转一段时间后，轴承温度逐渐降低并达到一个稳定值，这是因为滚动轴承开始运转时机器的负荷不稳定的缘故。所以，饲料粉碎机须开机空运转几分钟，才能进行粉碎作业。喂料结束后要让粉碎机继续运转几分钟，等到粉碎室内物料全部粉碎并排出后再停机。以上内容总结出了轴承质量、主轴转速、装配质量、润滑以及使用情况是影响饲料粉碎机轴承温升的主要因素，为用户判断轴承温升的异常提供参考。用户在使用饲料粉碎机的过程中应关注轴承温升的变化，出现异常时正确判断原因并及时处理。
