Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings.

[0014] see figure 1 Shown is a situation where the engine camshaft bearing cap and the cylinder head that can prevent wrong installation are accurately matched. The camshaft bearing cap body 1 is provided with a first mounting hole 3 and a second mounting hole 7. The first mounting hole 3 Located on the left side of the upper part 5 of the camshaft mounting hole on the camshaft bearing cap body 1, the second mounting hole 7 is located on the right side of the upper half part 5 of the camshaft mounting hole on the camshaft bearing cap body 1 ; The distance between the centerline of the first mounting hole 3 and the centerline of the camshaft mounting hole is less than the distance between the centerline of the second mounting hole 7 and the centerline of the camshaft mounting hole;

[0015] The first mounting hole 3 and the second mounting hole 7 coincide corresponding...

Abstract

The invention discloses an engine camshaft bearing cover capable of preventing false mounting. The camshaft bearing cover is characterized in that a camshaft bearing cover body is provided with a first mounting hole and a second mounting hole; the first mounting hole is positioned at the left side of an upper semi-circular arc of a camshaft mounting hole on the camshaft bearing cover body; the second mounting hole is positioned at the right side of the upper semi-circular arc of the camshaft mounting hole on the camshaft bearing cover body; the distance between a circle center of the first mounting hole and the center of the upper semi-circular arc of the camshaft mounting hole is less than the distance between a circle center of the second mounting hole and the center of the upper semi-circular arc of the camshaft mounting hole; the distance between the circle center of the first mounting hole and the circle center of the second mounting hole is equal to the distance between two circle centers of two threaded holes arranged on a cylinder cover; and the two threaded holes are respectively positioned at the left side and the right side of the lower semi-circular arc of the camshaft mounting hole. The engine camshaft bearing cover provided by the invention has the advantages of simple structure, is easy to manufacture, and the occurrence of false mounting of the camshaft bearing cover can be prevented effectively.

Description

technical field [0001] The invention relates to automobile engine parts, in particular to an engine camshaft bearing cap capable of preventing wrong assembly. Background technique [0002] The camshaft bearing cap is mainly used for radially limiting the camshaft on the engine. The center of the mounting bolt hole of the camshaft bearing cap used by the general engine has a symmetrical structure relative to the center of the camshaft hole on the camshaft bearing cap. [0003] In the production workshop, due to the fast pace of production, insufficient light and other reasons, the camshaft bearing cap may appear reversed. If the camshaft bearing cap is reversed, it will easily cause the camshaft to lock or increase the friction loss of the camshaft, which will affect the performance of the engine. Contents of the invention [0004] The object of the present invention is to solve the problems existing in the prior art, and provide a camshaft bearing cover that can prevent ...
