ECCENTRIC SHAFT ASSEMBLY HAVING FIXED AND MOVABLE ECCENTRIC MASSES

摘要

An eccentric shaft for a compacting machine is rotatable about a rotational axis and includes a fixed and movable eccentric mass where the movable eccentric mass cooperates with the fixed eccentric mass in one of the directions of rotation of the eccentric shaft to partly balance the fixed eccentric mass in the other rotation direction of the eccentric shaft. At least one section of the fixed eccentric mass shows a maximal radial extension (UB) in relation to the rotational axis, limited by an arc-shaped curve, which extends to a circle shape, with the diameter (D) showing a distance (A), between the point (P) on the circle-shaped curve that is located closest to the point of intersection of the rotational axis and the section plane, and the point of intersection, from 0 up to 0.1(D).

主权项

1. An eccentric shaft assembly for a compacting machine, the eccentric shaft assembly comprising:
an eccentric shaft rotatable about a rotational axis in first and second rotational directions; said eccentric shaft including a fixed eccentric mass and a movable eccentric mass; said movable eccentric mass coacting with said fixed eccentric mass in said first rotational direction and partly balancing said fixed eccentric mass in said second rotational direction; said fixed eccentric mass having a section defining a maximal radial extension (UB) with respect to said rotational axis; said maximal radial extension (UB) being delimited by an imaginary arc-shaped curve having a diameter (D) and being defined by points and/or segments of the outer periphery of said fixed eccentric mass; said fixed eccentric mass defining a section plane perpendicular to said rotational axis and said section plane and said rotational axis conjointly defining an intersection point; and, said imaginary arc-shaped curve having a point (P) thereon coinciding with said intersection point or said point (P) being on said imaginary arc-shaped curve at a location closest to said intersection point at a distance A≦0.1(D) therefrom.
