The visual perception of space form is part of the theory of form vision. The form vision has a close relation to architecture, visual art, theory of picturial formation and so on. This discourse briefly introduces the visual perception to space form for its fundemental perception, characteristics, and effectal factors in physiology and psychology, and is emphatically analyzing the visual perceptive characteristics of architectural space comprising the figure and size. There is certain meaning in organisation...

The visual perception of space form is part of the theory of form vision. The form vision has a close relation to architecture, visual art, theory of picturial formation and so on. This discourse briefly introduces the visual perception to space form for its fundemental perception, characteristics, and effectal factors in physiology and psychology, and is emphatically analyzing the visual perceptive characteristics of architectural space comprising the figure and size. There is certain meaning in organisation of architectural space. Meanwhile it has some value for reference in the field of relative sciences.

视觉对空间全景形象的感知问题,是形体视觉理论的一部分。形体视觉作为一门边缘科学,它对于建筑、美术、图形理论等有较密切的关系。本文简要耦述视觉对空间全景形象感知的生理和心理的基本过程、特征和影响因素,并着重对建筑空间的形状和尺度的视感知特征进行了一些具体的分析讨论。这对于建筑具有一定的实践意义,对有关视觉的学科也有一些参考价值。

A theoretical analysis of the problem under investigation in this paper is made principally for the double—arc gears which are used in practice nowadays. It leads to the conclusion. A pair. of mating double—arc gears, when viewed from front to back, will be in meshion simultaneously at both points, of which one is before and the other is after the pitch point, in spite of errors in center—distance and cutting—depth on condition that the parameters of their basic tooth profile satisfy that △ρ(1)=△ρ(2)=△ρ and...

A theoretical analysis of the problem under investigation in this paper is made principally for the double—arc gears which are used in practice nowadays. It leads to the conclusion. A pair. of mating double—arc gears, when viewed from front to back, will be in meshion simultaneously at both points, of which one is before and the other is after the pitch point, in spite of errors in center—distance and cutting—depth on condition that the parameters of their basic tooth profile satisfy that △ρ(1)=△ρ(2)=△ρ and α_(no)~((1))=α_(no)~((2))=α_(no)(See § 3) In paragraph § 4 a formula, which gives quantitative relation between errors and pressure angle,is exactly and simply derivated with the help of a diagram(Fig. 2)consisting of mating profiles in the transverse section. In paragraph § 5 the problem concerning the conservation of axile distance between neighbouring mesh—points is investigated. The last paragraph (§ 6) is a critique on the Reference [3].

本文主要针对目前在生产上实际应用的双元弧齿轮就所研究的问题作了理论分析,并得出下列结论:只要其基准齿形的参数满足条件△ρ~(1)=△ρ~(2)=△ρ、α_(no)~(1)=α_(no)~(2)=α_(no)就足以保证在节点前后同时啮合而不受中心距和切深偏差影响(见§3) 本文还利用端面齿廓啮合图(见图2)精确而简易地导出偏差和啮合角之间的定量关系式(见§4)。在§5中探讨了相邻啮合点间轴向距离的恒定性问题。最后一节(§6)是对文献[3]的评论。

This paper Presents a new method for calculating the conjugation problems in space by means of the priciple of projection rack--Method of medium rack in space. For a given non-involute gear, it is capable of establishing the simple equations for the basic worm conjugating with it. Some important features relating the conjugation of the basic worm with the gear under normal conjugate conditions are noted. Hence it givea s theore- tical basis for the design of an-involute gear hob by means of the theory...

This paper Presents a new method for calculating the conjugation problems in space by means of the priciple of projection rack--Method of medium rack in space. For a given non-involute gear, it is capable of establishing the simple equations for the basic worm conjugating with it. Some important features relating the conjugation of the basic worm with the gear under normal conjugate conditions are noted. Hence it givea s theore- tical basis for the design of an-involute gear hob by means of the theory of conjugation in apace. The paper also gives the formulas and example for the design of gear hob with straight flute and rake angle.

本文运用投影齿条原理提出了计算空间啮合的新方法——空问媒介齿条法。找到了由给定的非渐开线齿轮,求与它相共轭的基本蜗杆形状之间的简单关系式,并进而发现在正常啮合情况下,基本蜗杆与齿轮啮合中的一些重要特点,因而为实际使用中采用空间啮合原理设计非渐开线齿轮滚刀齿形提供了理论基础。本文还附有前角直槽滚刀齿形的计算公式和实例。
