Rotary clubs in Eastern Europe and communist nations were disbanded by 1945–46, but new Rotary clubs were organized in many other countries, and by the time of the national independence movements in Africa and Asia, the new nations already had Rotary clubs.
A sphere rotating (spinning) about an axis. Rotation or rotational motion is the circular movement of an object around a central line, known as an axis of rotation.A plane figure can rotate in either a clockwise or counterclockwise sense around a perpendicular axis intersecting anywhere inside or outside the figure at a center of rotation.
The cam can be seen as a device that converts rotational motion to reciprocating (or sometimes oscillating) motion. [clarification needed] [3] A common example is the camshaft of an automobile, which takes the rotary motion of the engine and converts it into the reciprocating motion necessary to operate the intake and exhaust valves of the cylinders.
A rotary actuator is an actuator that produces a rotary motion or torque. The simplest actuator is purely mechanical, where linear motion in one direction gives rise to rotation. The most common actuators are electrically powered; others may be powered pneumatically or hydraulically , or use energy stored in springs .
Rotary Watches' head office is now in the UK, and it is a wholly Chinese-owned company. Rotary offers a range of timepieces manufactured in Switzerland, together with a range of less expensive pieces made elsewhere, usually with movements from Japan which are then assembled in Japan or China.
The Geneva drive or Geneva mechanism is a gear mechanism that translates a continuous rotation movement into intermittent rotary motion. The rotating drive wheel is usually equipped with a pin that reaches into a slot located in the other wheel (driven wheel) that advances it by one step at a time. The drive wheel also has an elevated circular ...
Cartwheel animation. A cartwheel is a sideways rotary movement of the body. It is performed by bringing the hands to the floor one at a time while the body inverts. The legs travel over the body trunk while one or both hands are on the floor, and then the feet return to the floor one at a time, ending with the athlete standing upright.
The rotary incremental encoder is the most widely used of all rotary encoders due to its ability to provide real-time position information. The measurement resolution of an incremental encoder is not limited in any way by its two internal, incremental movement sensors; one can find in the market incremental encoders with up to 10,000 counts per ...
