摘要： Vibratory device (1) for compacting machine comprising a shaft (3), at least one eccentric mass (4,5,6) rotatable arranged around the shaft (3) and at least one motor (8) arranged around the shaft (3). The motor (8) is arranged for rotating drive of at least one of the eccentric masses (4,5,6) around the shaft (3). The motor (8) comprise a winding unit (9) connected to, the shaft (3) and a rotor (10) rotatable arranged around the shaft (3) and connected to at least one of the eccentric masses (4,5,6). The rotor (10) is arranged to be actuated by at least one magnetic field to rotation around the shaft (3) and the winding unit (9) is arranged to generate the magnetic fields which actuates the rotor (10) to rotation.

摘要： An eccentric shaft (1) for a compaction machine comprising at least one pair of straight circular cylindrical bearing seats (2,3) arranged on either side of a center of gravity (TP) of the eccentric shaft (1). The bearing seats (2,3) are arranged such that cylinder axes (4, 5) thereof approximately intersect or cross each other at a concave angle (V), less than 179.8 degrees, towards the center of gravity (TP) when the eccentric shaft (1) is at rest.

摘要： The present invention relates to a compacting roller (1) comprising a roller drum arrangement (3) comprising a first roller drum (9) and a second roller drum (11) arranged next to each other, a drive arrangement (13) comprising a first drive unit (15) arranged to rotate said first roller drum (9) and a second drive unit arranged to rotate said second roller drum (11), and a power supply (39). The compacting roller by further comprises a frame (5) which is connected to said roller drum arrangement (3), wherein said power supply (39) is attached to said frame (5) outside each of the first roller drum (9) and the second roller drum (11), and an electronic balancing system (43) for maintaining the compacting roller (1) in an upright position during operation.

摘要： The present invention relates to a method of controlling operation of a vibratory roller (1) comprising a roller drum (3) and a vibratory mechanism (2) having at least two amplitude settings. The method comprises operating the vibratory mechanism (2) in one of said at least two amplitude settings; maintaining a predefined phase angle by controlling the vibration frequency of the vibratory mechanism (2); monitoring a bouncing indication value (BIV), said bouncing indication value being calculated based on an acceleration signal indicative of the vertical acceleration of the roller drum (3); and turning off the vibratory mechanism (2) upon detection of a resonance meter value (BIV) that exceeds a predetermined bouncing value (BV), thereby preventing the vibratory roller from operating in a bouncing mode of operation.

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).
