AI Technical Summary

Problems solved by technology

This results in an impact of the bearing outer race against the crankcase causing energy to be transferred from the crankshaft assembly to the crankcase
Vibration of the crankshaft assembly inside the crankcase excites the crankcase in a certain way, causing engine noise (rough combustion)

Embodiment Construction

[0028] As shown in FIG. 1 , an engine 20 has a crankshaft assembly 1 supported by a bearing 10 and a bearing 11 , both of which are rolling bearings, such as ball bearings. Bearing 10 and bearing 11 are rigidly fixed on each side of crankshaft 22 . The crankshaft assembly 1 is connected to one end of the connecting rod 6 by a crank pin 8 . The other end of the connecting rod 6 is connected to a piston 7 housed in the cylinder block 5 . Crankshaft assembly 1 is contained in crankcase, and crankcase is made up of right crankcase 2 and left crankcase 3. The right crankcase 2 is provided with an oil passage 17 through which an oil pump (not shown) supplies pressurized oil to move parts of the engine 20 . The cast iron insert 12 and the cast iron insert 13 are integrally manufactured with the left crankcase 3 and the right crankcase 2 to accommodate the light aluminum alloy material of the left crankcase 3 and the right crankcase 2 . The bearing 10 and the bearing 11 are install...

Abstract

A dampened bearing assembly comprising a roller element bearing having a raceway confining at least one roller element and a race with a bearing surface for bearing against a bearing surface of an adjacent component; and means for supplying a pressurised fluid to said bearing surface of the race for dampening transmission of impact of the roller element bearing with the adjacent component in use. The dampened bearing assembly is suitable for internal combustion engine applications such as bearings for inclusion in crankshaft assemblies.

Description

technical field [0001] This invention relates to bearing assemblies for cushioning and noise reduction in various applications. The bearing assembly can be used in an internal combustion engine. Background technique [0002] Rolling bearings are commonly used in engines. This application involves the crankshaft of an engine. [0003] A crankshaft, connected with associated connecting rods, is used in internal combustion engines to convert the reciprocating motion of the engine pistons into unidirectional rotational motion about the axis of the crankshaft. The crankshaft assembly is housed in two structural elements called crankcases. The crankcase is usually divided into two elements, referred to in the following description as the left crankcase and the right crankcase, for the assembly of the crankshaft and other engine components to be housed in the crankcase. [0004] A piston assembly of an internal combustion engine reciprocates within cylinders and is connected to...
