Two eccentric parts two being located between two eccentric parts one；The eccentric direction of the eccentric part one and the eccentric part two
Eccentric direction is opposite；The top of the needle beam is connect using folding connecting rod one with the eccentric part one；The top of the counterweight beam
It is connect using folding connecting rod two with the eccentric part two.
In the technical scheme, crankshaft bears the power that needing machine power part transmits, and is transformed into torque and passes through song
Axis exports and needle beam and clump weight connected to it is driven to act；Two kinds of contrary eccentric parts being capable of balance crankshaft on crankshaft
Rotary centrifugal force and its torque, the reciprocal inertia force and its torque of needle beam and clump weight can also be balanced, when these power and power
When square itself reaches balance, the centrifugal force of the load reduction of crankshaft, crankshaft is reduced, and equipment operation is more stable.
In addition, above-mentioned interior centering type ultrahigh speed needing machine according to the present invention, can also have following optimal technical scheme：
As a preferred technical solution of the present invention, one He of eccentric part is formed to undercut slots on the ontology of the crankshaft
Eccentric part two；The side of the eccentric part one and the relatively described grooving of eccentric part two is concordant with the ontology of the crankshaft.
As a preferred technical solution of the present invention, bearing shell one, the folding connecting rod are installed in the eccentric part one
One connect with the outer circle of the bearing shell one.
As a preferred technical solution of the present invention, bearing shell two, the folding connecting rod are installed in the eccentric part two
Two connect with the outer circle of the bearing shell two.
It is each at corresponding two eccentric parts two in the top of the counterweight beam as a preferred technical solution of the present invention
It is provided with a connecting rod base；The bottom of the folding connecting rod two and the connecting rod base are connected.
As a preferred technical solution of the present invention, push rod is installed at the top of the needle beam；The top of the push rod
It is connected across the guide sleeve of needing machine, and with the bottom of the folding connecting rod one.
As a preferred technical solution of the present invention, the crank is between the eccentric part one and the eccentric part two
It is each provided with the bearing block connecting with needing machine.
The beneficial effects obtained by the present invention are as follows being：1. exactly the opposite with the bias outside traditional axis outer circle deviation, the present invention is public
The crankshaft opened is that axis outer circle is inwardly manufactured eccentric, greatly reduces the centrifugal force of operating, punch frequency is up to 1800 revs/min；
2. the stability that full symmetric crankshaft can greatly improve machine run；3. it is driven between crankshaft and folding connecting rod using bearing shell,
The load force of needing machine is improved, operation noise is considerably reduced；4. needing machine reduces two times of centrifugal force, at work
Current capacity also synchronize and reduce half；The service life of complete machine also promotes one third than original structure, has accomplished section completely
It can durable and efficient high-quality machine.
