 meshing
 Effects of Boundary Condition and Helix Angle on Meshing Performance of TI Worm Gearing With helix angle chosen as parameter, the criterion for the existence of meshing boundary line on the surface of TI worm gearing is derived. Results show that there can be four situations for meshing boundary line on the tooth surface of gear, namely, inexistence of meshing boundary line, a unique line, two lines, and two coincident lines. If the helix angle is equal to or slightly smaller than the bigger angle, which makes two meshing boundary lines superpose, a preferable meshing performance is obtained. In the following sections, some problems are discussed, such as the assembly form, the construction characteristics, the correct meshing condition, the continuum transmission condition and so on. 更多
 engagement
 Predawn xanthophyll cycle engagement was significantly greater in waterlogged than control saplings, despite relatively mild temperatures. The ideology of engagement groups suggested by us is considered. This paper considers shows how a service value networks (SVNs) approach may be engaged to model, and deliver, understanding of the front-end business and its direct engagement with its immediate (or front-end) customers. These three business-customer engagement areas of influence are captured by a SVN SEM approach. Daraus leitet sich perspektivisch ein zunehmendes Engagement der pharmazeutischen Industrie auch für Kinderarzneimittel ab. 更多
 mesh
 Anewwavelet-based geometric mesh compression algorithm was developed recently in the area of computer graphics by Khodakovsky, Schr?der, and Sweldens in their interesting article [23]. This leads to a very efficient geometric mesh compression algorithm as proposed in [23]. As a result, the algorithm in [23] outperforms several available geometric mesh compression schemes used in the area of computer graphics. We confirm here that the shifts and dilations of the wavelets used in [23] for the regular mesh, as expected, do indeed form a Riesz basis of L2(?2) by applying the more general theory established in this article. Our main result is that the rate of convergence of the two proposed iterative schemes depends only on the mesh norm and the 更多
 intermeshing
 This roughness enables intermeshing of layers, which constitutes the observed crystallographic contact. An experimental study of dispersion in compounds of polypropylene and polystyrene with calcium carbonate by mixing variously on two roll mills, an internal mixer, and a modular intermeshing co-rotating twin screw extruder. Analysis of shear-thinning fluid flow in intermeshing twin-screw extruders Selected flow fields are visualized grafically illustrating the intermeshing screw operation principle and demonstrating certain symmetries connected with the kinematic reversibility of nonlinear viscous creeping flows. In contrast, the linear extent of these junctions was remarkably large due to the intermeshing of the narrow apices of the secretory cells to form the tubular lumen. 更多
 In the paper, two complemental formulae are derived for using the relations of relative motion of the contact point to analyse the motion of plane mechanism with high-pair. By applying these formulae combined with the theorem of resultant of velocities and the theorem of resultant of accelerations, the motion of the driven element can he determined directly. Moreover, the velocity and the acceleration of the contact point can he determined as well. 本文导出了用啮合点的关系解平面高付机构问题的两个补充关系式。这两个补充关系式与速度合成定理及加速度合成定理相联系,即可直接求解机构从动件与主动件之间的运动关系,并且可以确定啮合点的速度及加速度。 In this paper the problem of mutual engagement between two arbitrarycurves in plane is discussed, thus providing a rule for modifying thecontours of the formative gear on the cross section of screw rod The basic results are as follows: 1. When a given piecewisely smooth cure (1)and an indeterminate curve in a plane engage each other in motion, weobtain the relation between the parameter λ and the rotational angleφ at the engaging point of the curves as shown by (3.17) in §3. Andew further derive from the relation... In this paper the problem of mutual engagement between two arbitrarycurves in plane is discussed, thus providing a rule for modifying thecontours of the formative gear on the cross section of screw rod The basic results are as follows: 1. When a given piecewisely smooth cure (1)and an indeterminate curve in a plane engage each other in motion, weobtain the relation between the parameter λ and the rotational angleφ at the engaging point of the curves as shown by (3.17) in §3. Andew further derive from the relation the basic law of mutual engagementbesween two gears. 2. The sufficient condition which a curve of mutual engagement withthe curve (1) exists uniquely is one of two conditions in §3 ((3.36)or (3.37)) and we find that the parametric expression of the curve ofmutual engagement with the curve (1) is (3.18) in §3. 3. In particular, when the curve (1) cosists of an arc ae of the epi-cycloid and the radial line segment ef or the circular arc eD (see thesecond figure in this paper), its engagement curve is respectivly givenby (4.23) or (4.51) in §4. These particular cases coincide exactly withthe known results applying in the designs of screw rod pumps. 本文讨论平面上任意两条曲线彼此间的啮合问题,这就为修改螺杆横截面上的型线提供了理论依据。所获得的基本结果如下: The purpose of the present paper lies in how to find out the solution of the addendum modification coefficients x_1 and x_2 when an operating pressure angle α′ has been given and the calculating value of the trochoidal interference G_s can be successively approximated to any prescribed value. 本文内容是当啮合角α′已指定,要向齿廓重迭干涉的验算值G_s为任意予期值逼近时,如何求变位系数x_1及x_2。用切线法迭代次数少,可类推用于求任意限制曲线上的点在α′为某数值时的位置,可用此方法绘封闭图。 << 更多相关文摘
