Description
Technical field
It the utility model is related to a kind of bent axle, the specifically bent axle easy to safeguard.
Background technology
Bent axle is the main rotation member of engine, and the up and down motion for accepting connecting rod becomes shuttling movement, bears connecting rod and transmits
Power and be transformed into torque and exported by bent axle and drive other annexes to work, be rotatablely connected between bent axle and connecting rod, it is bent
Acted on for a long time by frictional force between axis surface and bearing, connecting rod, the attrition of bent axle is very big, and existing crankshaft structure exists
Safeguard the shortcomings of inconvenient to use.
Utility model content
For above-mentioned deficiency, the purpose of this utility model is that, there is provided improve the lubrication of crankshaft surface, extension uses the longevity
Life, the bent axle easy to maintenance easy to maintain, cost is low.
To achieve the above object, the utility model provides following technical scheme：Easy to the bent axle of maintenance, including left connection
Axis, left crank arm, right connecting shaft, right crank arm and crank, left crank arm are set in left connecting shaft, left crank arm and left connection
Left positioning pin is connected between axis, right crank arm is set in right connecting shaft, and the right side is connected between right crank arm and right connecting shaft
Positioning pin, rotates the right side for being fixed with cylindrical crank, left connecting shaft left end and right connecting shaft between left crank arm and right crank arm
End is both provided with pouring orifice, and the oil supply gallery being connected with pouring orifice, oil supply gallery are both provided with left connecting shaft and right connecting shaft
It is connected with the oil outlet stretched out respectively outside left connecting shaft and right connecting shaft circumference.
The scheme further optimized, the crank both ends are rotated and are fixed on left crank arm respectively by shaft and bearing
On right crank arm.
The scheme further optimized, is provided with several oil grooves on the crank outer circumference surface.
The utility model has an advantageous effect in that compared with prior art：The utility model improves the profit of crankshaft surface
It is sliding, prolong the service life, it is easy to maintain, cost is low, it is easy to use.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model.
Figure label is：The left connecting shafts of 1-, the left crank arms of 2-, the right connecting shafts of 3-, the right crank arms of 4-, 5- cranks, 51- oil
The left positioning pin of groove, 6-, the right positioning pins of 7-, 8- pouring orifices, 9- oil supply galleries, 10- oil outlets, 11- shafts, 12- bearings.
Embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, is further elaborated the utility model.It should be appreciated that specific embodiment described herein is only explaining
The utility model, is not used to limit the utility model.
In the description of the utility model, it is to be understood that term " longitudinal direction ", " transverse direction ", " on ", " under ", " preceding ",
The orientation or position relationship of the instruction such as " rear ", "left", "right", " vertical ", " level ", " top ", " bottom ", " interior ", " outer " be based on
Orientation shown in the drawings or position relationship, are for only for ease of description the utility model, rather than instruction or the dress for implying meaning
Put or element there must be specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to the utility model
Limitation.
1 understand referring to the drawings, easy to the bent axle of maintenance, including left connecting shaft 1, left crank arm 2, right connecting shaft 3, right crank
Arm 4 and crank 5, left crank arm 2 are set in left connecting shaft 1, and left positioning pin is connected between left crank arm 2 and left connecting shaft 1
6, right crank arm 4 is set in right connecting shaft 3, and right positioning pin 7, left crank arm are connected between right crank arm 4 and right connecting shaft 3
Rotated between 2 and right crank arm 4 and be fixed with cylindrical crank 5, the right end of left 1 left end of connecting shaft and right connecting shaft 3 is both provided with
Pouring orifice 8, is both provided with the oil supply gallery 9 being connected with pouring orifice 8 in left connecting shaft 1 and right connecting shaft 3, oil supply gallery 9 connects
There is the oil outlet 10 stretched out respectively outside 3 circumference of left connecting shaft 1 and right connecting shaft；By the oiling into oil supply gallery 9 of pouring orifice 8,
Lubricating oil is flowed out through oil supply gallery 9 from oil outlet 10, enables crankshaft surface sufficient lubrication, strengthens the wear resistant corrosion resistant of bent axle
Property, fixation is attached by socket and left and right positioning pin 6,7 between left and right connecting shaft 1,3 and left and right crank arm 2,4, just
In demolition and maintenance and replacement.
Further, 5 both ends of crank rotated respectively by shaft 11 and bearing 12 be fixed on left crank arm 2 and
On right crank arm 4.
Further, several oil grooves 51 are provided with 5 outer circumference surface of crank；Improve between crank and connecting rod
Lubrication, prolong the service life.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
