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
Technical field
The present invention relates to a kind of motor, be specifically related to a kind of engine cam axle bearing framework.
Background technique
Motor mostly adopts to push away and very shakes the distribution device form when adopting the monomer cylinder head, and every cylinder adopts cyclinder head cover to realize the single cylinder sealing.The advantage of this combining form is that every cylinder forms independent seal oil system; There is not sealing influence each other to each other; Deficiency is to push away the high speed adaptability of very shaking distribution device to be not so good as double overhead mechanism; Bring up to a certain degree when the rotating speed of motor, pushing away very, the swing mechanism form will be difficult to guarantee reliability requirement.
Available engine camshaft bearing framework all is applied to overall cylinder cover, when being applied to the monomer cylinder head, and the seal oil existing problems.
Available engine camshaft bearing framework is divided into two-part up and down with the camshaft center, and two-part are overall structure, easy design casting and installation like this, but when certain independent bearing goes wrong, must integral body change.
Existing camshaft bearing framework is just realized the installation and the locating function of camshaft, does not have other functional structure to arrange above that.Function ratio is more single, does not make full use of design of part.
Summary of the invention
The purpose of this invention is to provide a kind of engine cam axle bearing framework; Can realize that Dual Over Head Camshaft uses on the monomer cylinder head; Satisfy the high-revolving usage requirement of motor; Can change bearing cap separately, and on the bearing framework, be designed with oil inlet hole and oil leab, make full use of design of part.
Technological scheme of the present invention is: engine cam axle bearing framework is made up of camshaft frame body 3 and camshaft bearing lid 4; Camshaft bearing lid 4 passes through bolton on camshaft frame body 3; Camshaft frame body 3 is provided with cyclinder head cover 5 and oil sprayer gland nut 2, and the camshaft bearing framework is installed on the cylinder head 1.
For realizing the sealing of single cylinder lubricant oil, camshaft frame body 3 is provided with sealing strip 6 with cylinder head 1 surface of contact.
Front end at camshaft frame body 3 and camshaft bearing lid 4 is provided with trapped fuel groove 7 and upper oil hole 8.
Rear end at camshaft frame body 3 and camshaft bearing lid 4 is provided with camshaft thrust surface 9.
On camshaft frame body 3 and camshaft bearing lid 4, at least one positioning pin hole 10 is set, guarantees the installation precision when camshaft bearing lid 4 repeats dismounting.
The present invention compared with prior art has following beneficial effect: can realize that Dual Over Head Camshaft uses on the monomer cylinder head; Satisfy the high-revolving usage requirement of motor; Can change bearing cap separately; And on the bearing framework, be designed with oil inlet hole and oil leab, made full use of design of part.
