AB型ROSTA振荡支座为免维护弹性摇杆,用于支撑或悬挂各种设计和驱动系统的自由振荡振动设备。它们在输送方向上辅助提供驱动力,并确保机器振荡部分的良好线性导向。振荡支座的受电弓结构允许在负载下产生较大的弹簧挠度,从而产生较低的固有频率(低至约2.2 Hz),因此对支撑结构具有极高的隔振效率。ROSTA振荡支座较高的横向稳定性可防止筛壳在通过共振频率时的摆动,这是螺旋弹簧装置的典型特征。
对于同样紧凑的设计,AB-D比AB具有更高的承载能力。荷载作用下的线性弹簧挠度仍然足以确保该振荡装置具有约3.2 Hz的相对较低的固有频率。在约16 Hz的振动器或波频率下,这足以使隔振效率达到约95%。与ROSTA的所有筛分机一样,AB-D的特性有助于筛分机的线性振荡运动。以控制方式通过共振时无需横向导向装置;支座横向稳定。这种低成本的振荡装置为所有未安装在“离地”较高的筛选平台或钢结构的设备提供了足够的隔振效果。
装置将通过直接用螺栓将钢支架安装到筛分机和支撑结构上。
尺寸AB-D 18至AB-D 45的双橡胶悬挂装置的外壳为铝型材,三种尺寸的AB 50则为球墨铸铁。

The oscillating mounting type AB-HD is the "Heavy Duty" version in the AB mount family of the ROSTA screen suspensions. For example the AB-HD type 50-2 offers 40 % more load capacity compared to the standard version AB 50-2 (14′000 instead of 10′000 N) by a slightly higher natural frequency (f = approx. 2,7 Hz instead of 2,3 Hz).
AB-HD筛分机支座是在可变装装载量下工作的矿筛和集料筛的理想悬挂,对可能发生的过载情况不太敏感。此外,由于承载能力高,这些支座也注定了筛分机承受冲击载荷的情况(例如,由前端装载机装载)。
所有AB-HD型振荡支座也可采用不锈钢制作(AISI 304),且与蓝色AB-HD型振荡支座互换!

The ABI-HD screen mount is the ideal suspension for mining- and aggregate screen working under variable charging capacities and are less sensitive on possibly occurring overload situations. Furthermore, due to the high load capacity, these mountings are also predestined for screens submitted to impact loading situations (e.g. charged by front-end loaders).
All ABI-HD oscillating mountings are in stainless steel (AISI 304) and interchangeable with the blue AB-HD oscillating mountings!
AB型ROSTA振荡支座因其高效的隔离效果、高水平的横向稳定性、过载安全性和较强的耐腐蚀性,在筛分技术中作为筛箱悬挂装置而享有盛名。

The new HSI suspensions (hanging screen) have a guide arm geometry that is designed for tensile loads. With ideal loading, the natural frequency of this suspension thereby sinks from its former 5.5 Hz to only approx. 3.5 Hz, which guarantees an isolating effect > 97 %.
