    • A scroll compressor performing three-dimensional compressions, which can optimize a tip clearance in operation while considering a thermal expansion and a pressure deformation and which can reduce a compression leakage to improve a compression efficiency thereby to realize a high performance. The leading end faces (13c and 13d) and the bottom face of a spiral wrap (13b) have a step portion (13e), and the wrap height on the outer circumference side of the spiral wrap (13b) is made larger than that on the inner circumference side wrap height. The spiral wrap (13b) on the inner circumference side with respect to the step portion (13e) is stepwise or continuously made gradually lower toward the center side of the spiral wrap (13b), and the tip clearance (Δi) of the spiral wrap on the inner circumference side with respect to the step portion (13) is made gradually larger toward the center side of the spiral wrap (13b).
    • 一种执行三维压缩的涡旋压缩机,其可以在考虑热膨胀和压力变形的同时优化操作中的顶端间隙,并且可以减小压缩泄漏以提高压缩效率,从而实现高性能。 前端面(13c,13d)和螺旋形包裹物(13b)的底面具有阶梯部(13e),螺旋形卷(13b)的外周侧的卷绕高度大于 内周侧包裹高度。 相对于台阶部(13e)的内周侧的螺旋形包裹体(13b)朝向螺旋形卷(13b)的中心侧逐渐或连续地逐渐变小,并且顶端间隙(&Dgr; i) 相对于台阶部(13)的内周侧的螺旋状卷绕部朝向螺旋形卷(13b)的中心侧逐渐变大。

    • The present invention relates to a vibration-proofing device which supports an upper structure, such as a building, computers and other machines or a floor having such machines mounted thereon, on a lower structure, as a foundation, to allow the upper structure to swing, thereby isolating earthquakes, traffic vibrations and vibrations from the equipment installed in another room so as to protect the upper structure from vibrations. The invention is to provide a bearing type of vibration-proofing device which is simple in construction and capable of reliably absorbing not only horizontal but also vertical components of earthquakes, traffic vibrations and other vibrations, whether they are weak or strong, and which properly operates under low load and produces little vibration during operation. The invention provides an arrangement wherein interposed between upper and lower structures are rolling bodies for horizontally supporting the upper structure for swing movement. The rolling bodies are in the form of cylindrical rollers, elastomeric bodies are interposed between the cylindrical rollers and the upper and lower structures. It is desirable that the cylindrical rollers be stacked in n rows and that these rows of cylindrical rollers form an angle of 180.degree. /n. An air spring or coil spring device is disposed vertically of the cylindrical rollers and a plurality of taper rollers is radially arranged in a horizonial plane vertically of the cylindrical rollers.
    • 防震装置技术领域本发明涉及一种防震装置,其将诸如建筑物,计算机和其它机器的上部结构或其上安装有这种机器的地板支撑在下部结构上作为基础,以允许上部结构摆动 从而从安装在另一房间的设备隔离地震,交通振动和振动,以保护上部结构免受振动。 本发明是提供一种结构简单,能够可靠地吸收地震,交通振动和其他振动的水平而且垂直分量,无论它们是弱还是强的并且适当地操作的轴承类型的防振装置 在低负载下运行时几乎不产生振动。 本发明提供了一种布置,其中介于上下结构之间是滚动体,用于水平支撑上部结构以进行摆动运动。 滚动体是圆柱形滚轮的形式,弹性体置于圆柱滚子和上下结构之间。 期望圆柱滚子以n行堆叠,并且这些圆柱滚子列形成180°/ n的角度。 空气弹簧或螺旋弹簧装置设置在圆柱滚子的垂直方向上,并且多个圆锥滚子径向布置在圆柱滚子垂直的水平平面中。
