Abstract
A biasing member assembled with a bearing and a crankshaft wherein the bearing is configured to receive the crankshaft. The crankshaft is assembled with an internal combustion engine. The biasing member biases the bearing in an axial direction relative to the crankshaft to reduce an endplay of the crankshaft while the engine is operable in a normal operating condition. The biasing member provides a resilient biasing force for biasing the bearing into engagement with a cylinder block when the crankshaft is operational to thereby eliminate or reduce the crankshaft endplay and improve the sealing performance of a crankshaft axial seal.
Claims20
An apparatus for a crankshaft of an internal combustion engine, the apparatus comprising:
- a bearing configured to receive the crankshaft;
- a biasing member positioned between the crankshaft and the bearing, wherein an axis of the biasing member is aligned with an axis of the bearing, the biasing member biases the bearing towards a cylinder block in an axial direction relative to the crankshaft to reduce an endplay of the crankshaft while the crankshaft is operational.
An apparatus for a bearing assembled with a crankshaft of an internal combustion engine, the apparatus comprising:
- a biasing member positioned between the crankshaft and the bearing, wherein an axis of the biasing member is aligned with an axis of the bearing, the biasing member configured to bias the bearing towards a cylinder block in an axial direction relative to the crankshaft to reduce an endplay of the crankshaft while the crankshaft is operational.
An apparatus for a bearing assembled with a crankshaft and a cylinder block of an internal combustion engine, the apparatus comprising:
- a biasing member positioned between the crankshaft and the bearing, wherein an axis of the biasing member is aligned with an axis of the bearing, the biasing member configured to bias the bearing into engagement with the cylinder block while the crankshaft is operational.
