Description
Technical field
This utility model belongs to bent axle technical field, especially relates to a kind of low noise single-cylinder air-cooled diesel engine bent axle.
Background technology
Bent axle on Diesel engine is the parts that convert reciprocating motion is circular motion of piston.At traditional diesel engine
On, bent axle often to drive distribution system by the vibroshock belt pulley of the flywheel He its front end that are arranged on its rear end and gear
System, fuel system, lubricating system etc..
In the course of the work, its side easily produces friction with connecting rod and makes noise bigger common crankshaft of diesel engine.?
In the middle of actually used process, if when electromotor runs into the loading of increasing suddenly, it may appear that the situation of crankshaft breakdown, easily pacify
Full accident, generation vibration is made noise increase by bent axle simultaneously.
Utility model content
In place of the purpose of this utility model is intended to solve the deficiencies in the prior art, and provide one can reduce Oscillation Amplitude,
Reduce the low noise single-cylinder air-cooled diesel engine bent axle of frictional force.
The purpose of this utility model is solved by following technical proposal:
A kind of low noise single-cylinder air-cooled diesel engine bent axle, including rod journal, is provided with left bent axle on the left of described rod journal
Arm, is provided with left trunnion on the left of left crank arm, be provided with right crank arm on the right side of described rod journal, is provided with right master on the right side of right crank arm
Axle journal, it is characterised in that: described rod journal left end and left crank arm junction have multiple first groove, and the plurality of first
Groove prolongs rod journal outer wall even circumferential and arranges；Described rod journal right-hand member and right crank arm junction have multiple second recessed
Groove, the plurality of second groove prolongs rod journal outer wall even circumferential and arranges, is all filled with in described first groove, the second groove
Cushion pad；
The right flank of described left crank arm, the left surface of right crank arm are equipped with nickel graphite composite bed.
Preferably, the material of cushion pad described in the utility model is nitrile rubber.
Preferably, the degree of depth of nickel graphite composite bed described in the utility model is 10～30 μm.
Compared to the prior art this utility model has the characteristics that and beneficial effect:
1, by offering groove at the link position of rod journal and left crank arm, right crank arm, and fill in groove
Cushion pad, effectively slows down bent axle impact force, it is to avoid bent axle ruptures, and reduces the vibration amplitude of bent axle simultaneously, reaches
Reduce the purpose of noise.
2, the right flank of crank arm, the left surface of right crank arm are equipped with nickel graphite composite bed, and graphite mechanical entrainment is in plating
In Ceng, antifriction effect is obvious, effectively reduces the frictional force between connecting rod and bent axle, reduces noise.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Fig. 2 is this utility model the first groove Longitudinal cross section schematic.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further details.
As it is shown in figure 1, a kind of low noise single-cylinder air-cooled diesel engine bent axle, including rod journal 1, described rod journal 1 is left
Side is provided with left crank arm 2, is provided with left trunnion 3 on the left of left crank arm 2, is provided with right crank arm 4 on the right side of described rod journal 1, right
Right trunnion 5 it is provided with on the right side of crank arm 4.
Described as shown in Figure 1, Figure 2, described rod journal 1 left end and left crank arm 2 junction have multiple first groove 6, institute
State multiple first groove 6 and prolong the setting of rod journal 1 outer wall even circumferential.Described rod journal 1 right-hand member and right crank arm 4 junction
Having multiple second groove 7, the plurality of second groove 7 prolongs rod journal 1 outer wall even circumferential and arranges, described first groove 6,
All being filled with cushion pad 8 in second groove 7, the material of described cushion pad 8 is nitrile rubber.By at rod journal 1 and left song
Armshaft 2, the link position of right crank arm 4 offer groove, and fill cushion pad 8 in groove, and that effectively slows down that bent axle is subject to rushes
Hit power, it is to avoid bent axle ruptures, reduce the vibration amplitude of bent axle simultaneously, reduce the purpose of noise.
The right flank of described left crank arm 2, the left surface of right crank arm 4 are equipped with nickel graphite composite bed 9, described nickel graphite
The degree of depth of composite bed 9 is 10～30 μm, and ink mechanical entrainment is in coating, and antifriction effect is obvious, effectively reduce connecting rod and bent axle it
Between frictional force, reduce noise.
Specific embodiment described herein is only to this utility model spirit explanation for example.This utility model institute
Belong to those skilled in the art described specific embodiment to make various amendment or supplement or use similar
Mode substitute, but without departing from spirit of the present utility model or surmount scope defined in appended claims.
