Articulated joint for machine part - consists of four connected parts of which two are at angle to other two

摘要

The articulated joint for a machine part comprises four elements, the first (1) with an axis (1.1), the second (2) fits on the first and rotates about its axis (1.1). The second part (2) has an upper flat surface (2.4) at an angle of forty five degrees to the axis (1.1) and the same angle to the seating (1.2) of the second part (2) on the first (1). A third part (3) sits on the upper surface (2.4) of the second (2) and has an axis (2.1) which intersects the axis (1.1) at a point (5). A fourth part (4) sits on the upper flat surface (3.3) of the third (3) and revolves on it. The first part (1) is fixed to a machine part and the second part (2) revolves on it, while the third part (3) revolves at twice the speed in the opposite direction. The fourth part (4) revolves in the opposite direction and at the same speed as the second part (2). ADVANTAGE - Can adapt to any angle of a related surface.
