Two push rod guide pin bushings, the bottom of the push rod guide pin bushing is fixedly connected by screw rod with needle beam, and the inside of the push rod guide pin bushing is installed
Have and capacity eccentric bearing is equipped with the top of needle beam connecting rod, two needle beam connecting rods, the two ends of the main shaft are respectively placed in two partially
The inside of heart bearing, the main shaft of the capacity eccentric bearing side is provided with spindle bearing holder, one of them spindle bearing holder
Side is provided with synchronous pulley, and the side of another spindle bearing holder, which is provided with the middle part of flywheel, the main shaft, is provided with two
Counterweight is eccentric, and the eccentric outer wall of two counterweights is connected by the two ends of counterweight connecting rod and counterweight beam.
As a kind of optimal technical scheme of the present utility model, the capacity eccentric bearing, spindle bearing holder, synchronous pulley, match somebody with somebody
Weight bias, flywheel, capacity eccentric bearing and main shaft are on same axis.
It is used as a kind of optimal technical scheme of the present utility model, the outer wall fixed cover of the synchronous pulley and flywheel and main shaft
Connect.
It is used as a kind of optimal technical scheme of the present utility model, a diameter of 45mm at the main shaft two ends.
The beneficial effect that the utility model is reached is：The axle center eccentric structure of this kind of needing machine, as a result of axle center
Eccentric structure, substantially reduces the diameter of eccentric wheel external diameter, reduces 3 times than original structure, equally centrifugal force is reduced during operating
3 times, because the reduction power consumption of centrifugal force has equally dropped 50%, the vibration and idle consume 50% of complete machine are reduced, due to reduction
Centrifugal force, the speed of mainshaft its vibration degree in the case of 2 times of original structure type is also lower than original structure, 2000 turns of this arrangement works
When it is almost without friction, it is ensured that the stability and service life of complete machine, while all electrical equipment controls can be directly mounted in machine,
The globality and operation convenience of machine are ensure that, because the eccentric whole external diameter in axle center reduces, makes the connecting rod weight reduction of use
18kg, whole reactive loss is substantially reduced.
