A camshaft seat assembly and bearing seat assembly group

Abstract

The invention relates to the technical field of engines, in particular to a camshaft seat assembly and a bearing seat assembly group, the first camshaft seat is used to be arranged on the cylinder head at intervals, and at least one upper There are two first lower half grooves at intervals on the first camshaft seat; it also includes the first camshaft cover, the lower part of which is provided with two first lower half grooves to form two first camshaft installations. The first upper half groove of the hole, the oil passage is connected with the first camshaft installation hole, the first fixed groove for installing the rocker shaft is arranged on both sides of the upper part of the first camshaft cover, and the first camshaft cover is provided with the second A threaded bottom hole, the oiling passage communicates with the first threaded bottom hole, a lubricating passage is provided in the first bolt matched with the first threaded bottom hole, and the lubricating passage communicates with the first fixing groove. The invention can solve the problems in the prior art that aluminum-based or copper-based cam bearing bushes are used as the carrier of friction and wear between the cam bearing seat and the camshaft, which easily causes accidents such as pull-outs.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to a camshaft seat assembly and a bearing seat assembly. Background technique [0002] The single cam bearing cover structure of the traditional engine can only play the role of fixing the camshaft except that there is a lubricating oil channel on the structure to lubricate the camshaft journal; therefore, the traditional cam bearing cover arrangement is difficult to be popular in modern times. It is applied to the double overhead camshaft and double rocker shaft structure engine. To this end, the rocker chamber designed with integrated cam bearing housing is introduced as a support for the valve train between the cylinder head and the cylinder head cover, and the double cam bearing cover is introduced to replace the single cam bearing cover, and the double cam bearing cover is given more Multiple functions; the valve mechanism lubricating oil passage and engine brake oil passage a...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the defects existing in the prior art, the purpose of the present invention is to provide a camshaft seat assembly and a bearing seat assembly, which can solve the problem of using aluminum-based or copper-based cam bearing bushes as cam bearing seats and camshafts in the prior art. The friction and wear between the carrier, the lubrication is not smooth or the hard abrasive particles such as impurities enter the inner layer of the cam bearing, which is easy to cause accidents such as pulling tiles
