introduction:1)The cumulative transmission clearance of the reducer。Because the mold shaking table is connected with the eccentric shaft through the connecting rod,The weight of the mould and shaker is very human(Gross re-reduction16t),When the mold is near the upper and lower door points,The torque direction of the eccentric shaft is abrupt,The meshing teeth of the reducer change from one side of the teeth to the other。The transmission of the reducer accumulates clearance time,It will cause the mold to vibrate
