Abstract
The utility model discloses a lubrication structure for a gas distribution camshaft for an engine, comprising a cylinder head, a lubricating oil passage of the cylinder head, a camshaft, a sliding bearing, a rolling bearing and other parts; wherein, a spiral lubricating oil passage is added on the shaft journal surface that the camshaft is matched with the sliding bearing; an oil hole for the sliding bearing communicated with the lubricating oil passage of the cylinder head is added in the sliding bearing. The utility model has the advantages that; the structure can enable the lubricating oil flow through the oil hole of the sliding bearing from the lubricating oil passage of the cylinder head before flow into the spiral lubricating oil passage; the structure can make lubricating oil for the camshaft journal and the surface of the sliding bearing distributed evenly, lower the failures of the engine, avoid locking for the camshaft and improve the stability for movement and service life of wear.
Description
Technical field
The utility model relates to the spirality lubricating structure of a kind of lubricating structure, particularly a kind of engines distribution cam axle.
Background technique
In the prior art, the unlubricated oil groove of camshaft for motorcycle engine and sliding bearing cooperation place, this lubricating system is fairly simple, but it is many to break down, and occurs the engine cam locking phenomenon easily; And wearing and tearing are big, reduced working life.
The model utility content
The purpose of this utility model is to reduce engine failure, prevents the camshaft locking, realizes the good lubrication between camshaft and the sliding bearing.
The technological scheme that addresses the above problem is: in the system that is made up of cylinder head, cylinder head oil leab, camshaft, sliding bearing, the journal surface that matches with sliding bearing at camshaft has the spirality oil leab, is provided with oilhole in the sliding bearing.This oilhole can be connected with the cylinder head oil leab.
The beneficial effects of the utility model are, method is simple, owing to increased camshaft screw lubrication oil groove, lubricant film is evenly distributed between camshaft and the sliding bearing thereby reach, and realizes the good lubrication between camshaft and the sliding bearing, frictional force is reduced, wearing and tearing reduce, and have relaxed the vibratory impulse between camshaft and the sliding bearing, have improved the stationarity and the friction durability of motion, prevented the camshaft locking, and then improved the working life of whole motor.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is an assembling schematic representation of the present utility model.
Fig. 2 is that Fig. 1 is along A-A direction cutaway view Amplified image.
Among the figure, 1-camshaft, 2-sliding bearing, 3-spirality oil leab, 4-cylinder head, 5-cylinder head oil leab, 6-oilhole.
Embodiment
Among Fig. 1, Fig. 2, in the system that forms by cylinder head 4, cylinder head oil leab 5, camshaft 1, sliding bearing 2, be processed with spirality oil leab 3 on the surface of the camshaft bearing journal that camshaft 1 matches with sliding bearing 2, be processed with oilhole 6 on the sliding bearing 2, oilhole 6 is connected with cylinder head oil leab 5.This camshaft 1 rotates in the direction of arrows; sliding bearing 2 remains static; lubricant oil flows into from the cylinder head oil leab 5 of cylinder head 4 in the oilhole 6 in the sliding bearing 2; and then flow in the spirality oil leab 3 of camshaft; after engine start, camshaft 1 rotation drives lubricant oil simultaneously and flows along spirality oil leab 3; make that the axle journal and the sliding bearing 2 surface lubrication oil content cloth of camshaft 1 are even, thereby reach the effect of protection camshaft 1.
Claims (2)
1. the lubrication groove of an engines distribution cam axle, form by cylinder head, cylinder head oil leab, camshaft, sliding bearing, it is characterized in that: the journal surface that matches with sliding bearing (2) at camshaft (1) has spirality oil leab (3), and oilhole (6) is arranged in the sliding bearing (2).
2. lubrication groove according to claim 1 is characterized in that: described oilhole (6) communicates with cylinder head oil leab (5).
