我厂立式手动千斤顶油缸成品件,如图1所示。由于其两端的螺纹、倒角及端面相对于油缸内孔的同轴度要求较高,加工时只能以内孔为基准装夹。以前我在普通卧式车床上设计和应用如图2所示的胀套胀紧心轴(以下简称普通心轴),它是由压紧螺母6带动锥套5运动,锥套5的 相似文献

正发动机制造技术缸盖主要用来封闭发动机气缸上部,构成燃烧室,并为凸轮轴和进、排气歧管提供支撑。发动机工作时,空气从进气歧管吸进燃烧室,火花塞把可燃混合气体点燃,带动活塞做功,并把废气从排气歧管排出。液压胀紧器作用在正时链条上,起着导向和涨紧的作用。如果缸盖的液压胀紧器孔(简称"胀紧器孔")存在缺陷,会造成发动机漏油,影响工作性能。缸盖胀紧器孔工废率高一直困扰着我公司,本文通过一个典型的QC小组(质量管理小组)的活动案例,介绍如何降低缸盖胀紧器孔工废率。 相似文献

In a recent paper, the Ritz method with simple algebraic polynomials as trial functions was used to obtain an eigenvalue equation for the free vibration of a class of homogeneous solids with cavities. The method presented is here extended to the study of a class of non-homogeneous solids, in which each solid is composed of a number of isotropic layers with different material properties. The Cartesian coordinate system is used to describe the geometry of the solid which is modelled by means of a segment bounded by the yz, zx and xy orthogonal coordinate planes and by two curved surfaces which are defined by fairly general polynomial expressions in the coordinates x, y and z. The surface representing the interface between two material layers in the solid is also described by a polynomial expression in the coordinates x, y and z. In order to demonstrate the accuracy of the approach, natural frequencies are given for both a two- and three-layered spherical shell and for a homogeneous hollow cylinder, as computed using the present approach, and are compared with those obtained using an exact solution. Results are then given for a number of two- and three-layered cylinders and, to demonstrate the versatility of the approach, natural frequencies are given for a five-layered cantilevered beam with a central circular hole as well as for a number of composite solids of more general shape. 相似文献

Specific features of operation of one- and two-capacitor microelectromechanical converters (MEMC) of energy of mechanical microscopic vibrations into electric energy with a modulated electrode-gap magnitude and with allowance for the mutual influence of electrical and elastic forces are analyzed, and the characteristics of these two devices are compared. The main factors restricting the increase in MEMC power are demonstrated to be the effects of “collapsing” and the condition of conservation of positive rigidity of the system. Expressions for estimating the limiting MEMC parameters are derived. The possibility of electrical energy generation in the presence of “real“ sources of wide-spectrum microscopic vibrations is considered. 相似文献
