With reference to attached drawing 2-5, a kind of high energy efficiency, low emission crankshaft rod assembly, including crank 1 and connecting rod 2；Crank 1 is
Discoid, one side is equipped with heavy platform, and heavy platform center is equipped with counterbore, and opposite side is coaxially arranged with multi-diameter shaft 3；Connecting rod 2, it is rotatable
Be set in outside axis pin 8, axis pin one end is fixed on crank 1, and axis pin is axial and the axis of crank 1 is arranged in parallel.
Bearing 4 is additionally provided between connecting rod 2 and axis pin.The both ends difference mirror symmetry setting of axis pin there are one crank 1 and its
Multi-diameter shaft 3.Counterweight plectane 5 is equipped with by bolt in counterbore, counterweight plectane 5 is arranged in heavy platform.It is laid on counterweight plectane 5
Multiple mounting holes 6 are equipped with, adjusting block 7 is fixed in mounting hole 6.
When specific implementation, counterweight plectane 5 and adjusting block 7 can detect state according to the dynamic balancing of 1 connecting rod 2 of crank
Be adjusted counterweight, need to increase with recanalization it is dynamically balanced when, first adjusting block 7 is installed on counterweight plectane 5, then will
Counterweight plectane 5 is installed in counterbore.
The above is only the preferred embodiment of the utility model, and the scope of protection of the utility model is not limited merely to
Above-described embodiment, all technical solutions belonged under the utility model thinking belong to the scope of protection of the utility model.It should refer to
Go out, for those skilled in the art, several improvement under the premise of the utility model principle is not departed from and
Retouching, these improvements and modifications also should be regarded as the scope of protection of the utility model.
