(Summary description)Motor position
① The rolling bearing for rotor shaft is seriously worn or the bearing accuracy is low.
② The rotor shaft is bent and deformed.
③ The installation position of carbon brush is incorrect.
④ Safety cover of rotor shaft end blade wiper motor.
(2) V-belt drive part
① The V-belt pulley of plastic sheet machine is not fixed firmly on the transmission shaft or the fit clearance between the two parts is too large.
② The manufacturing accuracy of pulley is low, and the end face or outer circle swing is large.
③ The poor installation quality of the active and passive pulleys makes the high-speed motion track of V-belt not on the same plane, resulting in working noise.
(3) Working parts of gear transmission
① The gear manufacturing accuracy is low and the pitch error is large.
② The center distance error of the transmission shaft of a pair of meshing gears is large. When the center distance is smaller than the standard, the interference sound between the teeth of the meshing transmission is generated; When the center distance is greater than the standard value, the impact sound will be produced.
③ The rolling bearing on the transmission shaft is worn seriously or the precision is low.
④ The center lines of the two transmission shafts on the gears are not parallel, so that the two gears can not mesh correctly.
⑤ The lubrication condition of a pair of meshing gears is poor. There is not enough lubricating oil
(4) Screw part of plastic sheet machine barrel
① The screw is assembled in the barrel, and the concentricity accuracy of the two parts is low.
② The perpendicularity error between the end face of the barrel and the flange end face of the barrel base and the center line of the barrel is large.
③ The screw is bent and deformed. The straightness error of the axis center line is too large.
④ The assembly clearance between the screw and its transmission shaft is too large. The center line of the two shafts is different from each other during the working rotation, so the error is large.
