圆锥破碎机的弹簧压力不足有什么影响?

可能很多人不知道圆锥破碎机的弹簧压力不足有什么影响,圆锥碎石机租赁厂家提示大家,一旦出现这种情况,很有可能会导致主轴断轴的!下面小编就给大家详细的普及一下!
Perhaps many people do not know what the impact of insufficient spring pressure cone crusher, cone crusher leasing manufacturer reminds you, once this situation occurs, it is likely to lead to spindle broken! The following edition will give you a detailed popularization!
超负荷作业:由于圆锥破碎机弹簧压力不足,超负荷时圆锥破碎机上部支撑套经常跳动,造成产品粒度过粗。所以操作人员常常采取再度压缩保险弹簧的办法增加破碎力,从而增大了主轴的受力,致使主轴承受过大的作用力;
Overload operation: Due to insufficient spring pressure of cone crusher, the upper support sleeve of cone crusher often jumps when overload occurs, resulting in coarse product size. Therefore, operators often take the method of re-compressing the safety spring to increase the breaking force, thereby increasing the force on the spindle, resulting in the main bearing being subjected to excessive force;
频繁的过铁和卡铁:碎矿车间为了获得合格的产品粒度,经常缩小拍矿口,造成破碎腔过铁或卡铁的次数增加,致使主轴危险断面内弯曲应力达到一定数值,导致圆锥式破碎机主轴断轴。
Frequent iron-crossing and iron-jamming: In order to obtain qualified product size, the crushing workshop often reduces the tapping mouth, resulting in an increase in the number of iron-crossing or iron-jamming in the crushing chamber, resulting in a certain value of bending stress in the dangerous section of the spindle, leading to a broken spindle of the conical crusher.

减少主轴静压合部分的过盈,减小主轴与圆锥躯体的配合过盈。为保证主轴与躯体在运转过程中不发生松动,则要求有一定的过盈。过盈量越大就越牢固,但是,应力集中亦随之增加,对主轴的疲劳强度降低就越严重;按新设计的弹簧压力,相应的设计了轴的嘶间,普遍加大了轴的直径;
The interference of the static pressing part of the spindle is reduced, and the fit interference between the spindle and the conical body is reduced. In order to ensure that the spindle and body do not loosen in the process of operation, a certain interference is required. The bigger the interference is, the firmer the shaft will be, but the stress concentration will also increase and the fatigue strength of the spindle will decrease more seriously.
增大主轴配合部分与锥体之间的过渡圈角,以减少应力集中系数;增加减载槽,将降低由压配合;将主轴与破碎圆锥躯体之间静压合部分的躯体下边缘处做成一圈减载槽;改善断轴部位的圆角形状,对主轴的静压合部分进行滚压加工,增加其表面光洁度和表面硬度。
Increase the transition circle angle between the spindle mating part and the cone to reduce the stress concentration factor; Increase the load-reducing groove to reduce the pressure matching; Make a circle of load-reducing groove at the lower edge of the body of the static pressing part between the spindle and the broken cone body; Improve the rounded shape of the broken part of the spindle and roll the static pressing part of the spindle. Press processing, increase its surface finish and surface hardness.
