Description
Technical field
The utility model is related to bent axle technical field more particularly to a kind of seperated bent axles.
Background technology
Bent axle, the gaseous-pressure that will act on piston top are changed into crankshaft torque and export to automotive transmission and drive hair
Other attachmentes work in motivation, and in order to reduce stress concentration, generated centrifugal force, bent when in order to reduce crankshaft quality and movement
Axis trunnion is often made hollow, and oilhole is provided in each journal surface, to introduce or draw machine oil, to moisten
Sliding journal surface, bent axle is severe because its operating condition, and crankshaft high-speed is needed to rotate, therefore, more next to the lubricating requirement of bent axle
It is higher.
In lubricating oil lubricant effect can be substantially reduced containing impurity；And due to the effect of centrifugal force, lubricating oil is out of bent axle
When being thrown on trunnion by oilhole, often along the Radial Flow of trunnion, lubricating oil covers main journal surface
Range is smaller, and lubricant effect is bad；Finally, existing bent axle is integrally formed substantially, seperated can not connect, not only cost
Height, and it is not easy to repair, and connection is insecure, and stability is relatively low.
Invention content
According to the above technical problem, the utility model provides a kind of seperated bent axle, it is characterised in that including the first connector,
Second connector, filtration, first connector include the first crank arm, trunnion, connecting rod, and the crank arm side is solid
There are connecting rod, the crank arm other side to be installed with trunnion, the trunnion is hollow structure, is opened on the trunnion surely
Equipped with diversion trench, oilhole is offered on the trunnion, the oilhole is communicated with diversion trench, and filtering knot is equipped in the oilhole
Structure, the filtration include small cylinder, screw rod, adsorbed film, and the small cylinder is mounted in oilhole, between the small cylinder and oilhole
It is threadedly coupled, the small cylinder inner wall is equipped with adsorbed film, is equipped with screw rod, the screw rod in the small cylinder in the axial direction
One end is connect by quarter butt with small cylinder inner wall, and described trunnion one end is equipped with the second connector, and second connector includes
Second crank arm, connecting rod, second crank arm side are equipped with annular groove, and described trunnion one end is mounted in annular groove, institute
It states the second crank arm other end and connecting rod is installed.
Through-hole is equipped in second crank arm, the through-hole is connected to trunnion.
It is interference fit between the annular groove and trunnion.
The beneficial effects of the utility model are：It is mounted with that filtration, lubricating oil pass through oilhole in the utility model oilhole
When outflow, the adsorbed film of small cylinder inner wall can be by the impurity absorption in lubricating oil, and when oilhole outflow, screw rod can be to lubrication
Oil plays the effect of turbulent flow so that lubricating oil is fully contacted with adsorbed film, enhances adsorption effect, spiral shell between filtration and oilhole
Line connects, therefore can remove filtration, is replaced to adsorbed film, lubricating oil can be along diversion trench when being flowed out from oilhole
It is flowed to the axial direction of trunnion, then under the influence of centrifugal force, lubricating oil is flowed out out of diversion trench, along the radial flow of trunnion
Dynamic, such lubricating oil can be covered with the surface of trunnion, enhance lubricant effect, finally, the first connector and the second connector
Between it is detachable, when there is deformation or damage, the first connector and the second connector can be dismantled and repair replacement, ring
Be interference fit between shape slot and trunnion, fit closely on the outside of the outer shroud side wall and trunnion of annular groove, annular groove it is interior
It is fitted closely on the inside of ring-side wall and trunnion, enhances the fastness of connection.

Specific implementation mode
Root according to the figure, is further described the utility model：
1 the utility model of embodiment is a kind of seperated bent axle, it is characterised in that including the first connector 1, the second connector
5, filtration 4, the first connector 1 include the first crank arm 1-1, trunnion 1-2, connecting rod 1-3, and connecting rod 1-3 is fixed on first
The sides crank arm 1-1, trunnion 1-2 are fixedly mounted on first other sides crank arm 1-1, and trunnion 1-2 is hollow structure, main shaft
Diversion trench 2 is offered on neck 1-2, oilhole 3 is offered on trunnion 1-2, and diversion trench 2 is communicated with oilhole 3, and filtration 4 is installed
In oilhole 3, filtration 4 includes small cylinder 4-1, screw rod 4-2, adsorbed film 4-3, and small cylinder 4-1 is threadably mounted in oilhole 3,
Adsorbed film 4-3 is mounted on small cylinder 4-1 inner walls, is equipped with screw rod 4-2 in small cylinder 4-1 in the axial direction, and the one end screw rod 4-2 is logical
