    • A saw blade (1) is provided which includes an inner collar (2) separated from an outer collar (18) with a resilient isolated layer (14). The inner collar (2) fastens to the arbor shaft (10) of a driving motor, while the outer collar (18) is welded to the rim (20) containing hardened particles, such as diamond bits. The inner and outer collars form inner and outer collar flanges (12, 16) which receive the resilient isolating material (14) therebetween. In an alternative embodiment, the inner and outer collars are separated from one another with a plurality of plugs (30) formed of resilient isolating material. The plurality of plugs (30) are formed in a circular pattern about the arbor shaft (18) and are spaced apart from one another. In another embodiment, a vibration dampening coupler (36) is fastened to the arbor shaft and formed separate from the cutting blade (48). The isolating resilient layer may be formed as a solid layer, as a plurality of O-rings, or with a void therein.
    • 提供锯片(1),其包括与具有弹性隔离层(14)的外轴环(18)分离的内轴环(2)。 内轴环(2)紧固到驱动电动机的心轴(10)上,而外轴环(18)焊接到包含硬化颗粒(例如菱形钻头)的边缘(20)上。 内圈和外圈形成在其间容纳弹性隔离材料(14)的内圈和外圈凸缘(12,16)。 在替代实施例中,内和外套环彼此分离,并具有由弹性隔离材料形成的多个塞子(30)。 多个塞子(30)围绕心轴(18)形成为圆形图案并且彼此间隔开。 在另一个实施例中,减振联接器(36)紧固到心轴,并与切割刀片(48)分开形成。 隔离弹性层可以形成为固体层,多个O形环或其中的空隙。

    • The nature and the use of this innovative invention is to cover a market demand for technical maintenance or integration interventions through the execution of holes in cement pipes, irrigation channels, drainage wells (with particular Attention to the "siphoned" wells such as Padua, Milan and the like), junctions of piping and piping of all types. In fact, to date, the problem of the realization of holes from the inside of the outwardly manufactured artifacts, albeit of extreme relevance, has not yet been solved with similar machines, exclusively mechanical, easy to carry, position and use and with dimensions so Which allow the use in any type of product from the smallest of 250mmX250mm. The invention is intended for use mainly in the field of engineering and construction but can also be used in other areas requiring special calibrated punctures and can also be considered as rapid intervention machinery in emergencies such as discharges or wells shut down without having to Provide the desiccation of the wastewater still present.
    • 该创新发明的性质和用途是通过在水泥管,灌溉渠道,排水井执行钻孔来满足技术维护或整合干预的市场需求(尤其要注意“ ;虹吸“井,如帕多瓦,米兰等),所有类型的管道和管道的连接点。 实际上,迄今为止,尽管具有极其相关性,但是从外部制造的制品内部实现孔的问题还没有用类似的机器解决,只有机械,易于携带,定位和使用并且尺寸如此 它允许使用最小尺寸为250mmX250mm的任何类型的产品。 本发明主要用于工程和建筑领域,但也可以用于需要特殊校准穿孔的其他区域,并且也可以被认为是紧急情况下的快速干预机械,例如关闭排放口或井,而不必提供干燥 的废水仍然存在。
