Abstract
The utility model relates to a bearing cover of camshaft in a diesel engine, comprising a group of camshaft bearing cover faces, a group of bolt holes used for fixing a cylinder cover and a group of screw holes used for fixing valve chamber cover. The utility model is characterized in that the camshaft bearing cover is a frame type structure; the frame is provided with the bolt holes used for fixing a cylinder cover and the screw holes used for fixing valve chamber cover; the camshaft bearing cover faces are distributed at two sides of the frame so as to fix the camshaft along with a first camshaft bearing cover. In order to lubricate the camshaft of an oil vapor pump, a group of oil grooves are opened on the frame. For the aim of secondary positioning, the frame around the camshaft bearing cover is provided with a positioning pin hole for fixing the bearing cover on the cylinder cover. As combining a group of camshaft bearing cover faces on an integrated frame, the whole intensity of the bearing cover is strengthened. As blending a plurality of assembling functions, the accessories are reduced so as to make the structure more compact. Two positioning pins are used for positioning so that the secondary positioning is simpler and more correct.
Description
Technical field
The utility model relates to a kind of camshaft-bearing cap of motor, relates to the camshaft-bearing cap of a kind of Dual Over Head Camshaft (DOHC) diesel engine in particular.
Background technique
General camshaft-bearing cap is a split-type structural, each axle journal that is camshaft distributes single bearing cap to be used for fixing, and oil supply is set on the bearing cap, and whether oil groove is also arranged.For 4 cylinder Dual Over Head Camshaft (DOHC) motors in upright arrangement, 9 or 10 independent bearing caps just must be arranged, number of spare parts many (bearing cap, clamping bolt, locating studs etc.), assembling is complicated.And for the needs of arranging, motor itself needs layouts such as oil sprayer, Injection Pump, vacuum pump and valve chamber cover, and these parts all need special structure and fix for it.Will cause number of spare parts more like this, and the space of influence layout, processing is installed locatees cumbersome.And if the camshaft-bearing cap second positioning locatees badly, cylindricity increases, and will influence the performance of camshaft.
Therefore design a kind of camshaft-bearing cap rational in infrastructure to seem very important of whole motor.
Summary of the invention
The technical problems to be solved in the utility model is, in order to remedy the deficiency of existing camshaft-bearing cap, and provides a kind of rational in infrastructure, camshaft-bearing cap that second positioning is good.
The utility model is to solve the problems of the technologies described above to adopt following technological scheme, a kind of diesel engine cam axle bearing cover, comprise one group of camshaft bearing capping, have stationary cylinder to cover one group of bolt hole of usefulness and fixing one group of tapped hole using of valve chamber cover, it is characterized in that: described camshaft-bearing cap is configured to frame type; Have on the framework and be fixed on one group of bolt hole using on the cylinder cap and fixing one group of tapped hole using of valve chamber cover; Described one group of camshaft bearing capping is distributed in the both sides of frame, with first camshaft-bearing cap stationary cam axle together.
For the needs of camshaft lubrication and Injection Pump, also have one group of oil groove on the framework.
For second positioning, on the frame of camshaft-bearing cap periphery, in addition bearing cap is fixed on the positioning pin hole on the cylinder cap.
Front end at frame is first camshaft-bearing cap, and the rear end is the fixing attachment face of vacuum pump and the attachment face of oil sprayer.
Be provided with the through hole of oil sprayer in the centre of frame, and the mounting hole of fixed via.
Good effect of the present utility model is because one group of camshaft bearing capping is integrated on the all-in-one-piece framework, to increase the bulk strength of bearing cap.Merged the function of multinomial assembling, reduced part, so that structure is compact more.Only two locating studs are used for the location, make second positioning simpler and more accurate.
Further specify the utility model below in conjunction with embodiment and accompanying drawing.
