Abstract
The utility model belongs to the field of mechanical technology, especially relates to a novel camshaft mechanism lubricating system used for a motorcycle engine. In the conventional lubricating system of gas distribution camshaft of motorcycle engine, the lubricating oil can not lubricate camshaft surface comprehensively and smoothly, thereby the wearing speed is high and the service lifetime of the motorcycle engine can be influenced. The novel cam mechanism lubricating system comprises a rocker arm support, a camshaft cooperated with the rocker arm, a rocker arm rotatably connected with the rocker arm support through a rocker arm shaft. The camshaft is connected with the rocker arm support through the bearing. A support oil channel is disposed in one side of the rocker arm support, and is communicated with the support screw hole oil channel disposed on the rocker arm support. An oil injection hole of the support oil channel points at an exhaust cam of the camshaft. The utility model has advantages of good lubrication, heat dissipation, cleaning, protection and sealing effect, ability of prolonging the service lifetime of all parts, and applicability in motorcycle engine industry.
Description
Technical field
The utility model belongs to field of mechanical technique, relates in particular to a kind of new type of cam mechanism lubrication system that is used for motorcycle engine.
Background technique
In the lubrication system of the valve cam of existing motorcycle engine, lubricant oil can not be comprehensively, lubricated cam face and cause the cam face inordinate wear smoothly, and the rate of wear is very fast, influences the working life of motorcycle engine.
The model utility content
The technical problems to be solved in the utility model is to overcome above-mentioned defective of the prior art; the spy provides a kind of reasonable segmentation oil circuit; accurately, the cam portion of camshaft lubrication swimmingly, make it to form oil film, the resistance of reducing friction; alleviate wearing and tearing; simultaneously, also take away the heat that the part friction is produced, the metal filings of flushing part surface; effectively reduce the oil turbine oil consumption, play the new type of cam mechanism lubrication system of lubricated, heat radiation, cleaning, protection and seal action.
For solving the problems of the technologies described above, this new type of cam mechanism lubrication system, the rocking arm that includes rocker arm support, the camshaft that matches with rocker arm support, is rotationally connected by pitman arm shaft and rocker arm support, above-mentioned camshaft is connected by bearing and rocker arm support, wherein, above-mentioned rocker arm support one side has the support oil duct, communicate with the support screw oil duct on being arranged on rocker arm support, above-mentioned rocker arm support inboard is provided with nozzle opening, its nozzle opening communicates with the support oil duct, and the exhaust cam of camshaft is pointed in the aperture of its nozzle opening.So design can be lubricated the direct alignment cam of lubricant oil surface, can not influence lubrication effect because of the swing of rocking arm.When cam is lubricated, make the surface of cam form oil film, the resistance of reducing friction alleviates wearing and tearing, simultaneously, also takes away the heat that the part friction is produced, and the metal filings of flushing part surface plays lubricated, heat radiation, cleaning, protection and seal action.
As optimization, the axis of above-mentioned support oil duct and the axis of the camshaft θ that has angle, wherein, 9 °≤θ≤11 °, the axis of above-mentioned nozzle opening becomes to intersect vertically with the axis of camshaft, and with the horizontal plane of the rocker arm support α that has angle, wherein, 14 °≤α≤16 °.So design makes rocker arm support still keep intensity preferably, simultaneously, makes that lubricant oil ejection position is more accurate.
As optimization, above-mentioned pitman arm shaft has the intake valve oil duct, the oil duct junction of its intake valve oil duct communicates with above-mentioned support screw oil duct, its pitman arm shaft outer wall has oil groove, is provided with the intake valve oil outlet in the oil groove, and above-mentioned intake valve oil outlet communicates with the intake valve oil duct, above-mentioned rocking arm and pitman arm shaft socket, above-mentioned oil groove is positioned at socket part, and the belled part of its rocking arm is provided with two oil outlets, and the aperture of its oil outlet is towards the cam of camshaft.So design, can have the effect of lubrication assistant to the cam of camshaft, its belled part by rocking arm is lubricated, and has intermittence, cooperates the rotation of cam, is lubricated targetedly.
The beneficial effects of the utility model are, can be accurate, be lubricated swimmingly, and form oil film in the lubricant housings, the resistance of reducing friction alleviates wearing and tearing.In lubrication system capable of circulation, lubricant oil has not only reduced friction and wear, but also the heat that is produced when having taken away the part friction, to playing the effect of heat radiation with part.Simultaneously, lubricant oil is also taken away the metal filings of part surface together, has guaranteed the bright and clean of part surface of contact, prolongs the working life of each part.
