Abstract
Methods and systems are provided for balancer shaft assemblies featuring bearing caps. In one example, a system may include a bearing cap connected to a housing surrounding a balancer shaft. The bearing cap may have faces which contact components of the balancer shaft. This contact may prevent movement of the balancer shaft in a particular direction.
Claims20
A balancer shaft assembly for an internal combustion engine comprising:
- a bearing cap positioned on a single bearing seat;
- and
- a balancer shaft configured to rotate within a bearing comprising the bearing cap,
- the bearing cap comprising first and second thrust control faces on opposing sides of the bearing cap, and the first and second thrust control faces form terminal faces of the bearing cap in an axial direction and define a maximum width of the bearing cap,
- wherein the balancer shaft comprises first and second components, and the first and second components are arranged on opposing sides of the terminal faces of the bearing cap.

A balancer shaft assembly for an internal combustion engine comprising:
- a bearing including a bearing cap connected to a single bearing seat, wherein the bearing cap includes bearing control faces on opposing sides of the bearing cap forming a maximum bearing cap width, and the bearing cap extending perpendicular to a balancer shaft;
- and
- the balancer shaft configured to rotate within the bearing, wherein the balancer shaft comprises first and second components arranged on opposing sides of the bearing control faces at a width greater than the maximum bearing cap width.
A balancer shaft assembly for an internal combustion engine comprising:
- a bearing including a bearing cap connected to a single bearing seat, wherein the bearing cap includes bearing control faces on opposing sides of the bearing cap extending perpendicular to a balancer shaft defining a maximum width of the bearing cap in an axial direction of the balancer shaft;
- and
- the balancer shaft configured to rotate within the bearing, the balancer shaft including a component with a component control face extending perpendicular to the balancer shaft;
- wherein the component control face and the bearing control face come into contact when an axial force acts on the balancer shaft.
