除了传输转子扭矩外,安装在破碎机中的锁定组件还会受到进一步的负载,例如弯矩和径向冲击。本文简要介绍了这些应用必须考虑的因素。还请观看视频,并了解现代影响破碎机的工作方式。
功能原理
影响破碎机根据撞击原理起作用。要粉碎的材料被配备有吹杆的旋转旋翼捕获,加速并扔向固定撞击壁(断路器板),从那里再次将其送入转子的压碎半径。
Fragmentation continues until the material being crushed is small enough to pass through the gap between the rotor and the breaker plates. The actual crushing process takes place when the material gets into contact with the blow bars and the breaker plates. In addition, the material is reduced in size by inter-particle collision.
要求
To reliably absorb the combined loads due to bending moments and radial impacts occurring in the impact crushers produced by KLEEMANN GmbH, the yield point of the individual rings of the locking assemblies had to be given particular attention, with the aim to exclude plastic deformation in the locking assembly itself. It must be ensured even in extreme cases, e.g. overload of the crusher, that no damage to the system can occur.
另一方面,在这种情况下不允许降低最小压力,因为这会导致所谓的“轴向转子徘徊”或由于拧紧腐蚀而导致的轴断裂。
解决方案
如果标准铃声设计无法满足要求,该公司与客户合作开发了量身定制的解决方案。对于Kleemann GmbH粉碎机,响脚架适应了系列RFN 7012和RFN 7015的锁定组件,以较高的屈服强度,较窄的锥度角度和较宽的推力环。多年来,这些解决方案已经在不同破碎机类型的严峻工作环境中成功运行。
Other application areas
Locking assemblies are also used in impact crushers for securing belt pulleys. The pulleys have to be fastened onto the crusher shaft in such a manner that the torques occurring at overload are safely transmitted until the pulley slips, or until the shear pin breaks.
As a provider of application-oriented solutions, Ringfeder fulfilled the specific requirements set forth by a customer by engineering an optimized design of one of their standard products. Optimum performance of the impact crusher is guaranteed.
