The linear drive comprises a housing, in which a first component (1) is displaceably mounted via a gear in rotation about an axis or the first component is flexibly rotated in the housing in rotation about a longitudinal axis. A second component (2) rotatably connected with the first ...
The standard way to compute a rotation about an arbitrary axis through the origin is to concatenate five rotation matrices. This note shows how vector algebra makes it easy to rotate about an arbitrary axis in a single step. Figure 1 shows a point P which we want to rotate an angle θ...
A rigid body has six degrees of freedom, three of translation and three of rotation. The most general motion of a rigid body can be separated into the translation of a body point and the rotation about an axis through this point (Chasles' theorem). In the general case the rotation axis ...

Each tooth has an upper surface (30) which is inclined to the rotary axis of the element by a greater angle than is the outer portion (26). Each tooth has side surfaces (32) which extend parallel to the rotary axis and have a maximum axial dimension (t) which is greater than 0.01,...
The invention is concerned with such turn indicators of the kind in which the rotor is journalled in a frame which is itself journailed for rotation about an axis perpendicular to that of the rotor, both axes being perpendicular...收藏 报错 分享 全部来源 求助全文 FreePatentsOnline ...
I. On uniform rotation about a fixed axis in some holonomic and anholonomic frames The principle of equivalence of general theory of relativity provides the possibility of studying rotation at uniform rates about a fixed axis with the hel... B Chakraborty,S Sarkar - 《Annals of Physics》 被...
1. the act of rotating as if on an axis e.g. the rotation of the dancer kept time with the music Synonym: rotary motion 2. a planned recurrent sequence (of crops or personnel etc.) e.g. crop rotation makes a balanced demand on the fertility of the soil ...
The torque, due to the weight of the arm, is balanced according to the angular position of the arm by a contrast spring acting perpendicular to the axis of rotation of the arm. The spring is controlled by a cam integral with the arm, is housed in a container closed by a wall acted ...
