Description
Technical field
This utility model belongs to Motorcycle Engine Technology field, is related to a kind of motorcycle engine crankshaft needle roller lubrication knot
Structure.
Background technology
Motor tricycle has light and flexible, cheap, the advantages of be suitable to load-carrying, thus deep is liked by consumers in general
Love, also promotes engine for motorcycle increasingly to develop toward huge discharge direction simultaneously, further, since thermic load is high, vehicle weight
Carry, road conditions are poor, the reason such as dust storm is big, rigorous service condition so that engine for motorcycle fault rate is also very high, because
This, how to reduce motor tricycle car engine fault rate becomes Ge great electromotor producer key technical problem urgently to be resolved hurrily
One of.
In institute is faulty, engine crankshaft problem is stood in the breach, and due to lubricating the bent axle needle bearing clamping stagnation causing
Or abrasion is to lead to one of major reason of engine crankshaft problem, limited by existing structure, engine lubricating oil is from right crank
After central oil passage hole enters crank-pin, needle roller is directly entered by the oil hole of crank-pin, needle roller is lubricated, once lubricating oil
In there is fine particle, the problems such as can directly cause needle roller clamping stagnation, thus affecting engine work.
Utility model content
In view of this, this utility model provides a kind of motorcycle engine crankshaft 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 motorcycle engine crankshaft needle roller lubrication system, including left crank, right crank and connecting rod, left crank and right song
It is connected with crank-pin, described interlinking lever end is set on this crank-pin, is provided with song between this interlinking lever end and crank-pin between handle
Axle needle roller, described right crank is provided with crank oil leab, and crank-pin is provided with lubrication oil duct, and by oil supplying hole with
Crank oil leab connects, and the opening end of described lubrication oil duct passes through the first oil channel plug sealing, this lubrication oil
It is provided with the oil hole supplying lubricating oil to bent axle needle roller, it is critical only that in road：In oil supplying hole in described lubrication oil duct
Second oil channel plug is installed and oil hole between, described oil supplying hole is located at the die cavity that the first oil channel plug and the second oil channel plug surround
Interior, this second oil channel plug offers lubricating oil via.
Lubricating oil enters after lubrication oil duct through crank oil leab, initially enters the first oil channel plug and the second oil duct
Fill in the die cavity surrounding, without being supplied directly to bent axle needle roller position, during electromotor work, under the action of the centrifugal force, die cavity
Granule in interior lubricating oil can be deposited in die cavity outer surface, and that is, on lubrication oil duct inwall, clean lubricating oil passes through profit
Lubricating oil via and oil hole enter bent axle needle roller, needle roller is lubricated, due to having carried out secondary filter to lubricating oil, greatly changes
It has been apt to the lubricant environment of bent axle needle roller.
Described lubricating oil via deviates the second oil channel plug center along away from left crank and right crank rotation axiss direction, due to
During electromotor work, lubricating oil also can move to lubrication oil duct outer rim under the action of the centrifugal force, and this structure is able to ensure that
Lubricating oil smoothly flows into lubricating oil via, enters bent axle needle roller position through oil hole.
Reliability for ensureing the second oil channel plug is installed, and described lubrication oil duct is provided with 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：
Using the motorcycle engine crankshaft needle roller lubrication system of above technical scheme, can to enter bent axle needle roller before
Lubricating oil is filtered again, prevents the granule foreign in lubricating oil from flowing into bent axle needle roller, greatly improves the profit of bent axle needle roller
Slip ring border, effectively reduces engine for motorcycle fault rate.
Brief description
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of crank-pin in this utility model.
Specific embodiment
The utility model is described in further detail with accompanying drawing with reference to embodiments.
Motorcycle engine crankshaft needle roller lubrication system as shown in Figure 1, including left crank 1, right crank 2, and connecting rod 3,
Be connected with crank-pin 4 between left crank 1 and right crank 2, connecting rod 3 end is set on this crank-pin 4, this connecting rod 3 end with bent
It is provided with bent axle needle roller 5 between handle pin 4.
The axially disposed crank oil leab 21 in right crank 2 center, crankpin 4 is correspondingly provided with crankpin oil leab
41, in conjunction with Fig. 2 as 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 are all fitted in crankpin oil leab 41 using interference mode, this
Form a die cavity between one oil channel plug 6 and the second oil channel plug 7, oil supplying hole 42 is located in this die cavity, and oil hole 43 is then located at and is somebody's turn to do
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, is entered by crank oil leab 21
Lubricating oil in crankpin oil leab 41 first flows in the die cavity that the first oil channel plug 6 and the second oil channel plug 7 surround, then through lubrication
