Problems solved by technology

This makes the machining of the shaft more complex and costly
[0005] In addition, shafts made of steel are particularly noisy, especially if there are steel gears on them that mesh with other gears

Embodiment Construction

[0031] The following detailed description is exemplary only and is not intended to limit the invention or the application and uses of the invention. Furthermore, there is no intention to be bound by any theory presented in the preceding background of the invention or the following detailed description. Exemplary embodiments are described with reference to the figures, rather than limiting application and use.

[0032] Some embodiments may include automotive systems 100 such as figure 1 and 2 As shown, it includes an internal combustion engine (ICE) 110 having an engine block 120 defining at least one cylinder 125 having a piston 140 coupled to rotate a crankshaft 145 . Cylinder head 130 cooperates with piston 140 to define combustion chamber 150 . A fuel and air mixture (not shown) is disposed in combustion chamber 150 and ignited, the resulting thermally expanding exhaust causes reciprocating motion of piston 140 . Fuel is provided through at least one fuel injector 160 a...

Abstract

A shaft assembly for an internal combustion engine includes at least one bearing journaled shaft rotatably supported in at least one bearing, and at least one bushing constrained in rotation with the shaft. The bushing is provided with a journal surface for a bearing. The shaft is made of a material different from and typically softer than the material of which the bushing is made.

Description

technical field [0001] The present invention relates to bearing journaled shafts of internal combustion engines and in particular to the mounting of these shafts to internal combustion engines. Background technique [0002] An internal combustion engine is provided with a rotatable shaft. As an example, an internal combustion engine is provided with a crankshaft that converts reciprocating motion of a piston into rotational motion, a camshaft that controls operation of engine valves, and one or more balance shafts that reduce vibration of the internal combustion engine. [0003] The shaft may be mounted in the internal combustion engine by bearings, such as roller or ball bearings, which allow the shaft to be journalled, ie rotatably supported, in one or more bearings. In other words, the bearing supports the shaft at the journal surface and allows the shaft to rotate relative to the internal combustion engine. [0004] In order to reduce the vibration, noise and friction ...
