The invention relates to a balancing shaft for a single-cylinder or multi-cylinder engine having at least one unbalanced weight portion (21, 22; 23, 24) and at least one bearing (16, 17), the at least one unbalanced weight portion (21, 22; 23, 24) being associated with the bearing (16, 17) and the bearing (16, 17) having a radial running face (18) which extends only partially over a periphery of the bearing (16, 17) and a centrifugal force which results during rotation of the balancing shaft (11) is situated within a region of the bearing (16, 17) that is formed by the running face (18) which extends partially over the periphery of the bearing (16, 17), wherein provision is made for at least one supporting surface (51) to extend partially over the periphery of the bearing (16, 17) and to be provided separate from the running surface (18).
A balancing shaft for a single-cylinder or multi-cylinder engine having at least one unbalanced weight portion and at least one bearing, the at least one unbalanced weight portion being associated with the bearing and the bearing having a radial running face which extends only partially over a periphery of the bearing and a centrifugal force which results during rotation of the balancing shaft is situated within a region of the bearing that is formed by the running face which extends partially over the periphery of the bearing wherein provision is made for at least one supporting surface to extend partially over the periphery of the bearing and to be provided separate from the running surface.
The balancing shaft as claimed in claimed 18, wherein the unbalanced weight portion is provided at an outer end of the basic element.
A balancing shaft for a single-cylinder or multi-cylinder engine having at least one unbalanced weight portion and at least one bearing, wherein the at least one unbalanced weight portion is associated with the bearing and the bearing has a radial running face which extends only partially over a periphery of the bearing, and a centrifugal force which results during rotation of the balancing shaft is situated within a region of the bearing that is formed by the running face which extends partially over the periphery of the bearing, wherein the partial running face of the bearing has a peripheral angle of less than 180°.
