Problems solved by technology

The advantage of this combination form is that each cylinder forms a separate lubricating oil sealing system, and there is no mutual sealing effect between each other. The disadvantage is that the high-speed adaptability of the thrust valve mechanism is not as good as that of the double overhead mechanism. When the engine speed increases to To a certain extent, it will be difficult to guarantee the reliability requirements in the form of push, lift and shake mechanism
The function is relatively single, and the part structure is not fully utilized

Embodiment Construction

[0019] The engine camshaft bearing frame is composed of a camshaft frame body 3 and a cam bearing cover 4. The cam bearing cover 3 is fastened to the camshaft frame body 4 by bolts. The camshaft frame body 3 is provided with a valve chamber cover 5 and an injector The screw sleeve 2 is compressed, and the camshaft bearing frame is installed on the cylinder head 1.

[0020] In order to realize the sealing of the lubricating oil of the single cylinder, a sealing band 6 is provided on the contact surface of the camshaft frame body 3 and the cylinder head 1. Glue can be applied to the sealing belt area to realize the direct contact and seal between the frame and the cylinder head, without the need for sealing gaskets and other structures to ensure the center position of the transmission after the camshaft is installed.

[0021] An oil reservoir 7 and an oil hole 8 are provided at the front ends of the camshaft frame body 3 and the cam bearing cover 4.

[0022] A camshaft thrust surface ...

Abstract

The invention relates to an engine and particularly relates to an engine cam shaft bearing frame. The device consists of a cam shaft frame body (3) and a cam bearing cover (4), wherein the cam bearing cover (4) is tightly fixed on the cam shaft frame body (3) through a bolt, a cylinder head cover (5) and a fuel injector compact bolt sleeve (2) are arranged on the cam shaft frame body (3), and the cam shaft bearing frame is installed on a cylinder cover (1). The engine cam shaft bearing frame provided by the invention has the advantages that a double overhead cam shaft can be applied to a single cylinder cover, the use requirement of high rotating speed of the engine can be satisfied, the bearing cover can be independently replaced, and an oil supply hole and a lubricating oil channel are designed on the bearing frame, thus the part structure can be fully utilized.

Description

[0001] Technical field [0002] The invention relates to an engine, in particular to an engine camshaft bearing frame. Background technique [0003] When the engine adopts a single cylinder head, most of it adopts the form of a push-up-and-sway valve mechanism, and each cylinder adopts a valve cover to realize single-cylinder sealing. The advantage of this combination is that each cylinder forms a separate lubricating oil sealing system without mutual sealing influence. The disadvantage is that the high-speed adaptability of the push-and-stagger valve mechanism is not as good as the double overhead mechanism. When the engine speed is increased to To a certain extent, it will be difficult to guarantee the reliability requirements by pushing and shaking the structure. [0004] The existing engine camshaft bearing frames are all applied to the integral cylinder head, and when applied to the single cylinder head, there is a problem with the lubricating oil seal. [0005] The existing en...
