It is cheap in cost, simple in process, long in durability, improved in changing efficiency, being able to change forming line on the in and out gas cam within two days, with high strength, good toughness, less wearing for the matching part, low in noise, applicable for volume production and batch production in modules.
Description
(1), affiliated technical field
The present invention relates to a kind of general gasoline engines accessory, particularly small-sized general purpose petrol engine cam axle.
(2), technical background
Original general purpose petrol engine cam axle is generally the full-metallic one-piece camshaft, and it has advantages such as intensity height, good toughness and inlet and outlet cam long service life.But there is the manufacture cycle long, manufacture cost is high, be unfavorable for the multiple batches of production of small lot, be subjected to machining error to influence shortcomings such as big, and driving gear is hard tooth, operating noise is big, moreover camshaft is enterprising, the shape line of exhaust cam, can need change along with the regular variation of design, this is for the full-metallic one-piece camshaft, and shape line of every change needs to spend 20 Working days usually at least, operational sequence is comparatively complicated, and it is very low to change efficient; In addition, a kind of all-plastic one-piece camshaft is arranged also, it has advantages such as stable drive, transmission noise are low, but its thermal distortion is big, conformity be cannot say for sure card, can cause power to descend and discharging exceeds standard because of thermal distortion during use, more and more causes the attention of industry.
(3), summary of the invention
Purpose of the present invention just provide a kind of with low cost, technology is easy and the general purpose petrol engine cam axle of long service life, it can improve the replacing efficient of camshaft overhead cam significantly.
The objective of the invention is to realize by such technological scheme, it includes axle, gear, intake cam and exhaust cam, it is characterized in that: by being integral by the cam locking mechanism is affixed each other between the inlet and outlet cam in the tape spool hole of powdered metal sintering or non-powdered metal extrusion moulding and the axle.
In the present invention, axle is the branch body structure with cam, is solidified as a whole each other by the cam locking mechanism, and constituting camshaft, its connects firm and assembling and dismantle very convenient.When shape line enterprising when camshaft, exhaust cam will change because of the demand that designs, the operator just can directly carry out operation to the inlet and outlet cam, process needed shape line, the operation of this process is simple, inlet and outlet cam on the camshaft just can be changed in two days, the quick and convenience of the ten minutes that operates.Simultaneously, the inlet and outlet cam that adopts the powdered metal sintering to form, not only process easy, intensity is high, and is and with low cost, greatly reduces the cost of camshaft.
Owing to adopted technique scheme, that the present invention has is with low cost, technology is easy and the advantage of long service life, it can improve the replacing efficient of camshaft overhead cam significantly, shape line on the inlet and outlet cam just can be changed in two days, while intensity height, good toughness, little to the wearing and tearing of counterpart, and noise is low, and the modular construction that it had is fit to small lot, multiple batches of production.
