Abstract
The utility model provides a front bearing cover of a cam shaft, which is applied to the technical field of engines. The front bearing cover comprises a front bearing cover body (1); the inner surfaces of two cam shaft covers (2) of the front bearing cover body (1) are respectively provided with more than one concave oil groove I (3); and the oil grooves I (3) on the two cam shaft covers (2) are respectively arranged into structures which guide lubricating oil flowing out of an OCV (oil control valve) to a lagging cavity of a cam-shaft phase regulator and an advancing cavity of the cam-shaft phase regulator. The front bearing cover provided by the utility model has the advantages that not only are the requirements on positioning and fixing intake and exhaust cam shafts met, but also the lubrication for the cam-shaft phase regulator and a cam-shaft journal can be realized by arrangement of the oil grooves I and an oil groove II, so that the requirement of the engine on the lubrication under severe working conditions is met.
Description
Technical field
The utility model belongs to technical field of engines, more particularly, relates to a kind of camshaft front bearing retainer.
Background technique
In the existing technology field; The main function of the camshaft front bearing retainer of motor is to satisfy the location of inlet and outlet camshaft and fixing for the camshaft front bearing retainer through motor; But existing camshaft function singleness, can not apply engine the requirement aspect lubricated under bad working environments.
The model utility content
The utility model technical problem to be solved is: to the deficiency of existing technology, provide a kind of simple in structure, the camshaft front bearing retainer of lubrication needs that can engine components.
Solve above-described technical problem, the technological scheme that the utility model is taked is:
The utility model is a kind of camshaft front bearing retainer; Comprise the front bearing retainer body; Above together recessed oil groove I is set respectively on two camshaft cover internal surfaces of described front bearing retainer body, and the oil groove I on described two camshaft covers is set to respectively the lubricant oil that flows out in the OCV valve is directed to the advance structure in chamber of camshaft phase controller lag chamber and camshaft phase regulator.
On described two camshaft covers the oil groove I that twice are arranged in parallel is set respectively.
Above together recessed oil groove II is set on the internal surface of the median surface of described front bearing retainer body, and described oil groove II is set to the lubricant oil that flows out from cylinder cap is directed to the structure at camshaft bearing journal position.
Adopt the technological scheme of the utility model, can obtain following beneficial effect:
The camshaft front bearing retainer of the utility model; Except satisfy to the location of inlet and outlet camshaft and fixing; Can also be through the setting of oil groove I and oil groove II; Realization is lubricated to camshaft phase regulator and camshaft bearing journal position, thus can apply engine the requirement aspect lubricated under bad working environments.
Description of drawings
The mark of facing down among expressed content of each accompanying drawing of this specification and the figure is made briefly bright:
Fig. 1 is the structural representation of facing of the described camshaft front bearing retainer of the utility model;
Fig. 2 is the structural representation of the internal surface of the described camshaft front bearing retainer of Fig. 1;
Be labeled as among the figure: 1, front bearing retainer body; 2, camshaft cover; 3, oil groove I; 4, median surface; 5, oil groove II.
Embodiment
Contrast accompanying drawing below; Through description, the effect of the mutual alignment between the shape of the embodiment of the utility model such as related each member, structure, the each several part and annexation, each several part and working principle etc. are done further to specify to embodiment:
Shown in accompanying drawing 1, accompanying drawing 2; The utility model is a kind of camshaft front bearing retainer; Comprise front bearing retainer body 1; Above together recessed oil groove I 3 is set respectively on two camshaft cover 2 internal surfaces of described front bearing retainer body 1, and the oil groove I 3 on described two camshaft covers 2 is set to respectively the lubricant oil that flows out in the OCV valve is directed to the advance structure in chamber of camshaft phase controller lag chamber and camshaft phase regulator.
On described two camshaft covers 2 the oil groove I 3 that twice are arranged in parallel is set respectively.
Above together recessed oil groove II 5 is set on the internal surface of the median surface 4 of described front bearing retainer body 1, and described oil groove II 5 is set to the lubricant oil that flows out from cylinder cap is directed to the structure at camshaft bearing journal position.
The camshaft front bearing retainer of the utility model, except satisfy to the location of inlet and outlet camshaft and fixing, can also be through the setting of oil groove I 3 and oil groove II 5; When current bearing cap was installed to motor, camshaft and front bearing retainer fitted, at this moment; Form poroid oil duct between the oil groove I 3 of groove-like and the camshaft; At this moment, can pass through this oil duct, the lubricant oil that just flows out in the OCV valve is directed to camshaft phase controller lag chamber and the camshaft phase regulator chamber of advancing respectively; And the oil groove II 5 on the median surface, when front bearing retainer was installed to motor, camshaft and front bearing retainer fitted; At this moment; Form poroid oil duct between the oil groove II 5 of groove-like and the camshaft bearing journal, at this moment, can pass through this oil duct; Realization is lubricated to the camshaft bearing journal position, thus can apply engine the requirement aspect lubricated under bad working environments.
Combine accompanying drawing that the utility model has been carried out exemplary description above; Obviously the concrete realization of the utility model does not receive the restriction of aforesaid way; As long as adopted method design of the utility model and the various improvement that technological scheme is carried out; Or the design of the utility model and technological scheme are directly applied to other occasions without improving, all in the protection domain of the utility model.
