Claims26
A balancing shaft for a combustion engine comprising:
- at least one unbalance portion and at least one bearing point, wherein the at least one unbalance portion is associated with the at least one bearing point, and
- wherein the balancing shaft on the bearing point defines a transverse passage opening which separates a first part bearing surface from a second part bearing surface, the second part bearing surface extending over a smaller circumferential angle than the first part bearing surface.
A combustion engine comprising:
- at least one balancing shaft having at least one unbalance portion and at least one bearing point, wherein the at least one unbalance portion is associated with the at least one bearing point, and
- wherein the balancing shaft on the bearing point defines a transverse passage opening which circumferentially separates a first part bearing surface from a second part bearing surface.
A balancing shaft for a combustion engine, comprising:
- at least one unbalance portion and at least one bearing point, wherein the at least one unbalance portion is associated with the at least one bearing point;
- and
- wherein the at least one bearing point defines a transverse passage opening separating a first part bearing surface extending partially over a circumference of the bearing point from a second part bearing surface extending partially over the circumference of the bearing point.
