Description
Technical field
The utility model is related to a kind of motorcycle engine, especially a kind of motorcycle engine crankshaft is assisted into oil machine
Structure.
Background technology
In existing motorcycle engine, the mode of oil is got rid of by bent axle mostly for the lubrication of the cylinder holes of its engine
Or it sets up the mode that Special oil nozzle sprays and carries out.It is lubricated if cylinder holes cannot obtain enough machine oil, starts rapidly resulting in
, which there is scuffing of cylinder bore even power failure, in machine to be run.
Currently, the mode for getting rid of oil by bent axle carries out the structure of cylinder holes lubrication, needed mostly by increasing oil duct in crank
Oil inlet ensures that oil mass is sufficient, and still, this oil inlet mode leads to complicated integral structure.
Utility model content
The purpose of this utility model is just to provide a kind of motorcycle engine crankshaft auxiliary simple in structure, high lubricating effect
Oil-inlet mechanism.
The purpose of this utility model is that technical solution in this way is realized, a kind of motorcycle engine crankshaft assist into
Oil machine structure includes the right case with fuel feed hole, and the song that one end is connect by bearing with right case is provided in the right case
Axis is provided with the oil sealing disk penetrated on bent axle, the oil sealing disk and axis between the bearing and bent axle and on bent axle
It holds and surrounds reserve chamber.
Wherein, uniformly distributed on the end face of the oil sealing disk corresponding shaft bearing side to be arranged and be used for and the right side there are three perpendicular end surface
The stud of babinet connection.
It further describes, the stud includes threaded cylindrical body, and one end of the cylindrical body is provided with square
Shape connector, the rectangle connector are connect with the rectangular opening being arranged on oil sealing disk.
In order to improve sealing effect, it is provided between the oil sealing disk and bearing and is connect respectively with right case and oil sealing disk
Sealing ring.
Wherein, the sealing ring is circular body, and the semicircle with circular body one is provided in the circular body
Arc, the fuel feed hole are located in the semi arch.
Wherein, the bearing is the deep groove ball bearing with one-sided metallic dustproof cover.
By adopting the above-described technical solution, the utility model is with simple in structure, ingenious in design, low-cost excellent
Point is not only able to be lubricated cylinder holes using it, and can also provide lubrication to big end needle bearing so that connecting rod,
Cylinder body, piston are stable, extend service life of aeroengine, scuffing of cylinder bore, piston ring mill caused by avoiding cylinder holes lack of lubrication
The generation of phenomena such as damage, gas blowby.
Description of the drawings
The description of the drawings of the utility model is as follows：
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the oil sealing disk and sealing ring structural scheme of mechanism of the utility model.
Specific implementation mode
Specific embodiment of the present utility model is described in further detail below in conjunction with the accompanying drawings, but the utility model
These embodiments are not limited to, any improvement or replacement on the present embodiment essence spirit still falls within the utility model
Claim range claimed.
Embodiment 1：As shown in Figure 1, a kind of motorcycle engine crankshaft assists oil-inlet mechanism, include the right side with fuel feed hole 1
Babinet 2 is provided with the bent axle 4 that one end is connect by bearing 3 with right case 2 in the right case 2, in the bearing 3 and song
The oil sealing disk 5 penetrated on bent axle 4 is provided between axis 4 and on bent axle 4, the oil sealing disk 5 surrounds reserve with bearing 3
Chamber.
Wherein, on the end face of 5 corresponding shaft bearing of oil sealing disk, 3 side it is uniformly distributed be arranged there are three perpendicular end surface and for
The stud 6 that right case 2 connects.
Further, the stud 6 includes threaded cylindrical body 7, and one end of the cylindrical body 7 is provided with rectangle
Connector 8, the rectangle connector 8 are connect with the rectangular opening being arranged on oil sealing disk 5.
In order to enable sealing effect is good, be provided between the oil sealing disk 5 and bearing 3 respectively with right case 2 and oil sealing
The sealing ring 9 that disk 5 connects.
Wherein, the sealing ring 9 is circular body, and the semicircle with circular body one is provided in the circular body
Arc 10, the fuel feed hole 1 are located in the semi arch 10.
Further, the bearing 3 is the deep groove ball bearing with one-sided metallic dustproof cover.
In the utility model, lubricating oil is entered by the fuel feed hole 1 on right case 2 by bearing 3, sealing ring 9 and oil sealing
The reserve intracavitary that disk 5 surrounds, then enters bent axle draw-off tray from shoe cream room, hence into lubrication big end and leads to
It crosses bent axle and gets rid of oil and achieve the purpose that lubrication to cylinder holes.
