Description
Technical field
The utility model relates to a kind of oil supply structure, particularly a kind of bearing lubrication oil supply structure.
Background technique
Bearing lubrication principle on an existing class cam opening device arm shaft is splash lubrication, when its cardinal principle is camshaft rotation, cam bit takes lubricant oil on the overhead cam rotor in the swing arm being meshed with it, then in overhead cam rotor rotation process, oil is splashed in the baffle plate diversion groove between swing arm, then through the plane bearing between swing arm, flow into and treat lubricating bearings place, thereby realize the lubricated of bearing.Yet this lubrication principle exists certain defect, the in the situation that of low speed, lubricant oil is difficult to get rid of to bearing place by cam bit, thereby causes bearing oil starvation, causes the damage of bearing and other correlated parts in the situation that of long time running.
Model utility content
The utility model provides a kind of bearing that solves to cause the oil supply structure damaging because of oil starvation.
The technological scheme that the utility model addresses the above problem is:
A kind of bearing lubrication oil supply structure, comprise arm shaft, eccentric spindle nose, bearing cap and swing arm bearing, described arm shaft bearing sleeve is contained on arm shaft, described eccentric spindle nose is arranged on the end of arm shaft, described bearing cap is arranged on the outer end of eccentric spindle nose by locating stud, described arm shaft inner shaft is to having fuel supply chamber, described arm shaft inner radial evenly has a minute oilhole, within described minute, oilhole one end communicates with fuel supply chamber, the other end leads to the rolling element position of described swing arm bearing, described eccentric spindle nose inner shaft is to also having fuel supply chamber, two described fuel supply chambers communicate, and locating stud is connected with the fuel supply chamber of eccentric spindle nose inside.
On the basis of technique scheme, the utility model can also be done following improvement,
Further, described locating stud has through hole, and described through hole communicates with the fuel supply chamber of eccentric spindle nose inside;
Further, two described fuel supply chambers, all in eccentric position, are convenient to processing like this;
Further, it also comprises lubricating cup, and described lubricating cup is arranged in the through hole of locating stud.
The beneficial effects of the utility model are:
1. the utility model utilizes the cooperation of fuel supply chamber and minute oilhole, can guarantee under any speed conditions, and bearing all can have oil to be lubricated;
2. the utility model is simple in structure and structural stability is reliable, can meet lubricated requirement, and only need on original structure, improve under any runnability, and manufacture cost is lower, can effectively overcome the shortcoming of original structure.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of a kind of bearing lubrication oil supply structure described in the utility model specific embodiment;
In accompanying drawing, the list of parts of each label representative is as follows:
1, arm shaft, 2, eccentric spindle nose, 3, bearing cap, 4, swing arm bearing, 5, locating stud, 6, fuel supply chamber, 7, minute oilhole, 8, rolling element, 9, fuel supply chamber, 10, through hole, 11, lubricating cup.
Embodiment
Below in conjunction with accompanying drawing, principle of the present utility model and feature are described, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
A kind of bearing lubrication oil supply structure as described in Figure 1, comprise arm shaft 1, eccentric spindle nose 2, bearing cap 3 and swing arm bearing 4, described swing arm bearing 4 is sleeved on arm shaft 1, described eccentric spindle nose 2 is arranged on the end of arm shaft 1, described bearing cap 3 is arranged on the outer end of eccentric spindle nose 2 by locating stud 5, described arm shaft 1 inner shaft is to having fuel supply chamber 6, described arm shaft 1 inner radial evenly has minute oilhole 7, within described minute, oilhole 7 one end communicate with fuel supply chamber 6, the other end leads to rolling element 8 positions of described swing arm bearing 4, described eccentric spindle nose 2 inner shafts are to having fuel supply chamber 9, described fuel supply chamber 9 one end communicate with fuel supply chamber 6, the other end is connected with described locating stud 5, described locating stud 5 has through hole 10, described through hole 10 communicates with fuel supply chamber 9, described fuel supply chamber 6 and fuel supply chamber 9 are in eccentric position, it also comprises lubricating cup 11, described lubricating cup 11 is arranged in the through hole 10 of locating stud 5.
The primary lubricant principle of this structure is: by increase the oil feeding line of pressure type on correlated parts, make each treat that lubricating bearings place has lubricant oil to arrive herein, thereby realize the lubricated of bearing, concrete fuel feeding route is: lubricating cup 11 → locating stud 5 → eccentric spindle nose 2 → arm shaft 1 → swing arm bearing 4.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
