Abstract
The utility model discloses a crank shaft with oil filling holes, which comprises a main shaft neck, a balancing weight, a connecting rod neck, a crank shaft big end, a crank shaft small end, an oil supply hole, and oil filling holes. The utility model is characterized in that more than one oil filling hole is added on the main shaft neck, and the oil filling holes are communicated with the oil supply holes. The utility model has the advantages of reasonable and simple structure, lubrication enhancement and high durability and that the burning losses of connecting rods bushings can be prevented efficiently and the service life of the complete machine is extended. The utility model is suitable for being used on crank shafts of various automobiles and motor vehicles.
Description
The utility model belongs to bent axle, particularly a kind of oilhole bent axle that helps.
Existing motor is in operation process, oilhole shortage of oil in the bent axle and produce a large amount of bubbles, thereby produced initial stage waste gas, cause the piston of internal body, cylinder sleeve generation qualitative change is worn and torn too early, because the oil supply system of bent axle is from middle past two fuel feeding, thereby two oil pressure deficiency, can not go up connecting rod position, cause easy burning connecting rod bearing shell.
The purpose of this utility model be to provide a kind of simple and reasonable, strengthen lubricated, durable, prevent connecting rod bearing shell scaling loss, prolongation complete machine working life effectively help the oilhole bent axle.
Technical solution of the present utility model is such.Comprise by main journal, equilibrium block, connecting rod neck, big small crankshaft head, upper oil hole, help oilhole.The overall structure of bent axle is not done big change with at present commercially available, is also keeping the upper oil hole of structure originally between main journal and the connecting rod neck, and the connection using method of crankshaft installed on diesel engine is constant.But help oilhole more than one in the main journal increase, help oilhole to communicate, help oilhole or mutually oblique connection perpendicular, help the corresponding size in oilhole aperture with the upper oil hole aperture with upper oil hole with upper oil hole.
The utility model has the advantages that simple and reasonable, strengthen lubricated, durable, prevent connecting rod bearing shell scaling loss, prolongation complete machine working life effectively.Be suitable for bent axle use on the various automobile Motor Vehicle.
Below in conjunction with drawings and Examples to the utility model further instruction.
Fig. 1 is an overall structure view of the present utility model.
Fig. 2 is that the A-A that presses among Fig. 1 of the present utility model is to sectional view.
Fig. 3 is that the B-B that presses among Fig. 1 of the present utility model is to sectional view.
Among Fig. 1～Fig. 3, bent axle microcephaly (1), help oilhole (2), upper oil hole (3), equilibrium block (4), connecting rod neck (5), main journal (6), bent axle major part (7).
Most preferred embodiment of the present utility model is such, and the integral body of bent axle is close with crankshaft of diesel engine structure commonly used, but increase helps oilhole to communicate with former upper oil hole on main journal.The main journal (6), equilibrium block (4), connecting rod neck (5), bent axle microcephaly (1), the bent axle major part (7) that specifically are bent axle are close with conventional bent axle, its from equilibrium block (4) to main journal (6), or upper oil hole (3) is arranged from main journal (6) to the bent axle microcephaly, between the major part (1,7) with commonly used close, be communicated with crankshaft two end in the same old way, help oilhole more than (2) one but increase is logical on main journal (6), help oilhole (2) φ more than 1 millimeter, this bent axle is selected 6 millimeters of φ for use, help oilhole (2) with upper oil hole (3) but vertically communicate also that oblique communicates.Hole (2) and the corresponding size in hole (3), the utility model helps the oilhole bent axle to be used for 6105QC and/or 6108Q crankshaft of diesel engine, also can be used for four-cylinder.
Claims (2)
1, a kind of oilhole bent axle that helps comprises by main journal, equilibrium block, connecting rod neck, big small crankshaft head, upper oil hole, it is characterized in that main journal (6) increase of crankshaft of diesel engine helps oilhole more than (2) one, helps oilhole (2) to communicate with upper oil hole (3).
2,, it is characterized in that helping oilhole (2) and vertical the communicating of upper oil hole (3), but also oblique communicates according to the described oilhole bent axle that helps of claim 1.
