By the scheme disclosed by the invention, the outboard engine is fully lubricated by combining pressure lubrication with splash lubrication, and the service life is effectively prolonged.
Description
Technical field
The present invention relates to a kind of outboard machine bent axle pressure splash lubrication device, belong to the technical field of structures of outboard machine.
Background technique
Present outboard machine is when being lubricated, and the mode of employing has two kinds: pressure lubrication and splash lubrication; The pressure lubrication mode is used the oil pump fuel feeding, each lubricating point of machine oil coercively fed, but pressure lubrication can both be adopted in the lubricated position of not all needs, each axle journal of bent axle, camshaft etc. are pressure lubrication, but connecting rod small end, cylinder, piston etc. then are the oil lubricatings that splashes behind the dependence crankshaft lubrication, and splash lubrication is without oil pump, simple structure but get rid of oil is difficult to oil is supplied with bearing from the outside, therefore need a kind of lubricating fitting that is lubricated in conjunction with dual mode.
Summary of the invention
Technical problem for above-mentioned existence the objective of the invention is: proposed a kind of outboard machine bent axle pressure splash lubrication device in conjunction with pressure lubrication and splash lubrication.
Technical solution of the present invention is achieved in that a kind of outboard machine bent axle pressure splash lubrication device, comprises casing, and oil pump, cam assembly, piston rod part, crankshaft group, bearing are installed in the casing; Be provided with casing oil groove, intercommunicating pore, bearing oil groove in the described casing; Described casing oil groove is connected with bearing oil groove by intercommunicating pore; Offer the camshaft oilhole on the described cam assembly; Described oil pump one end is installed in the casing, and the other end is connected with cam assembly; Described cam assembly one end is connected with oil pump, and the other end is installed in the casing oil groove; Described piston rod part matches with cam assembly; Described crankshaft group comprises bent axle, crank throw, bent axle fan plate, gear; On the described crankshaft group bearing is installed, and installs and fixes by casing; Offer crankshaft hole on the described bent axle; Described crank throw is connected with piston rod part; Described crank throw two ends are provided with bent axle fan plate; Described bent axle fan plate is arranged in the oil baffle.
Because the utilization of technique scheme, the present invention compared with prior art has following advantages:
A kind of outboard machine bent axle pressure splash lubrication device of the present invention by pressure lubrication is combined with splash lubrication, is realized pressure lubrication by oil pump, realizes splash lubrication by crankshaft group, oil baffle etc.; By dual mode outboard machine is lubricated fully like this, effectively raise working life.
Description of drawings
Below in conjunction with accompanying drawing technical solution of the present invention is described further:
Accompanying drawing 1 is the structural representation of outboard machine bent axle pressure splash lubrication device of the present invention;
