Description
Technical field
The invention belongs to Motorcycle Engine Technology field, relate to a kind of engine for motorcycle bent axle needle roller lubrication knot
Structure.
Background technology
Motor tricycle has light and flexible, cheap, is suitable to the advantages such as load-carrying, thus is deeply liked by consumers in general
Like, also promote engine for motorcycle increasingly to develop toward huge discharge direction, additionally, due to thermic load is high, vehicle weight simultaneously
The reason such as load, road conditions is poor, dust storm is big, rigorous service condition so that engine for motorcycle fault rate is the highest, because of
How this, reduce motor tricycle car engine fault rate and become the key technical problem that Ge great electromotor producer is urgently to be resolved hurrily
One of.
In institute is faulty, engine crankshaft problem is stood in the breach, and the bent axle needle bearing clamping stagnation caused due to lubrication
Or abrasion is one of major reason causing engine crankshaft problem, being limited by existing structure, engine lubricating oil is from right crank
After central oil passage hole enters crank-pin, the oil hole of crank-pin it is directly entered needle roller, needle roller is lubricated, once lubricating oil
In there is fine particle, can directly cause the problems such as needle roller clamping stagnation, thus affect engine work.
Summary of the invention
In view of this, the present invention provides a kind of engine for motorcycle bent axle needle roller lubrication system, for motor tricycle
The lubrication of bent axle needle roller in car engine crank linkage.
Its technical scheme is as follows:
A kind of engine for motorcycle bent axle needle roller lubrication system, including left crank, right crank and connecting rod, left crank and
Connecting between right crank has crank-pin, described interlinking lever end to be set on this crank-pin, sets between this interlinking lever end and crank-pin
Having bent axle needle roller, described right crank to be provided with crank oil leab, crank-pin is provided with lubrication oil duct, and passes through fuel feeding
Hole connects with crank oil leab, and the opening end of described lubrication oil duct is sealed by the first oil channel plug, and this crank-pin moistens
Being provided with the oil hole to bent axle needle roller supply lubricating oil in grease way, it it is critical only that: is supplying in described lubrication oil duct
Second oil channel plug is installed, the type that described oil supplying hole is positioned at the first oil channel plug and the second oil channel plug surrounds between oilhole and oil hole
Intracavity, this second oil channel plug offers lubricating oil via.
Lubricating oil, after crank oil leab enters lubrication oil duct, initially enters the first oil channel plug and the second oil duct
In the die cavity that plug surrounds, without being supplied directly to bent axle needle roller position, during electromotor work, under centrifugal action, die cavity
Granule in interior lubricating oil can be deposited on die cavity outer surface, i.e. lubrication oil duct inwall, and clean lubricating oil is by profit
Lubricating oil via and oil hole enter bent axle needle roller, are lubricated needle roller, owing to lubricating oil has been carried out secondary filter, greatly change
It is apt to the lubricant environment of bent axle needle roller.
The second oil channel plug center is deviateed away from left crank and right crank rotation axis direction in described lubricating oil via edge, due to
During electromotor work, lubricating oil also can move to lubrication oil duct outer rim under centrifugal action, and this structure is able to ensure that
Lubricating oil flows into lubricating oil via smoothly, enters bent axle needle roller position through oil hole.
For ensureing the reliable installation of the second oil channel plug, described lubrication oil duct is provided with in the second oil channel plug installation site
Positive stop lug boss.
Described first oil channel plug and the second oil channel plug all with lubrication oil duct interference fit, with convenient for assembly and guarantee
Oil channel sealing performance.
Beneficial effect:
Use the engine for motorcycle bent axle needle roller lubrication system of above technical scheme, it is possible to entering bent axle needle roller
Front lubricating oil filters again, prevents the granule foreign in lubricating oil from flowing into bent axle needle roller, greatly improves bent axle needle roller
Lubricant environment, effectively reduce engine for motorcycle fault rate.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the structural representation of crank-pin in the present invention.
Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the invention will be further described.
Engine for motorcycle bent axle needle roller lubrication system as shown in Figure 1, including left crank 1, right crank 2, with even
Bar 3, connects between left crank 1 and right crank 2 and has crank-pin 4, connecting rod 3 end sleeve to be located on this crank-pin 4, this connecting rod 3 end
And it is provided with bent axle needle roller 5 between crank-pin 4.
Right crank 2, centrally along axially arranged crank oil leab 21, crankpin 4 is correspondingly provided with crankpin oil leab
41, in conjunction with Fig. 2 it can be seen that this crankpin oil leab 41 is through to crankpin 4 right-hand member end along crankpin 4 center, and lead to
Cross the first oil channel plug 6 to seal, crankpin oil leab 41 is communicated with to crank oil leab 21 oil supplying hole 42 and to
Bent axle needle roller 5 supplies the oil hole 43 of lubricating oil, is provided with the second oil channel plug 7 between oil supplying hole 42 and oil hole 43.
First oil channel plug 6 and the second oil channel plug 7 all use interference mode to be fitted in crankpin oil leab 41, this
Forming a die cavity between one oil channel plug 6 and the second oil channel plug 7, oil supplying hole 42 is positioned at this die cavity, and oil hole 43 is then positioned at this
Outside die cavity, the second oil channel plug 7 is provided with the lubricating oil via 71 that lubricating oil can be made to pass through, crank oil leab 21 enters
In the die cavity that lubricating oil in crankpin oil leab 41 first flows into the first oil channel plug 6 and the second oil channel plug 7 surrounds, then through lubrication
Oil via 71 flows into oil hole 43 side, enters bent axle needle roller 5 and is lubricated.
Lubrication oil duct 41 is provided with inwardly projecting positive stop lug boss 44 in the second oil channel plug 7 installation site, to ensure
The reliable installation of the second oil channel plug 7, the second oil channel plug 7 structure is roughly the same with the first oil channel plug 6 structure, all uses steel material
Making, the lubricating oil via 71 on the second oil channel plug 7 deviates second to the direction away from left crank 1 and right crank 2 rotation axis
Oil channel plug 7 center.
During engine work, lubricating oil flows into the first oil duct in lubrication oil duct 41 from crank oil leab 21
In the die cavity that plug 6 and the second oil channel plug 7 surround, under centrifugal action, granule foreign is stacked on die cavity outer wall, and clean
Lubrication have, flow into from lubricating oil via 71 and oil hole 43 and at bent axle needle roller 5, bent axle needle roller 5 be lubricated.
It is last it should be noted that foregoing description is only the preferred embodiments of the present invention, the ordinary skill people of this area
Member, under the enlightenment of the present invention, on the premise of present inventive concept and claim, can make table as multiple types
