Analysis of the causes of large noise in the work of plastic sheeting machines:
(1) Motor parts
1、Serious wear of rolling bearing for rotor shaft or low precision of bearing.
2、The rotor shaft is bent and deformed.
3, Carbon brush installation work position is incorrect.
4、The rotor shaft end wind blade scrapes the motor safety cover.
(2) V-belt transmission parts
1, plastic sheet machine V belt pulley in the transmission shaft is not firmly installed or two parts with large clearance.
2, low manufacturing accuracy of the belt pulley, end face or outer circle swing large.
3, poor installation quality of the main and passive pulleys, so that the V-belt high-speed trajectory is not in a? plane, producing working noise.
(3) Gear transmission working parts
1、Low manufacturing accuracy of gears, large tooth pitch error.
2, a pair of meshing gears drive shaft centre distance error, centre distance and standard regulations when small, resulting in gear meshing transmission inter-tooth interference sound; centre distance greater than the standard specified value, resulting in gear meshing transmission work impact sound.
3、Serious wear or low precision of rolling bearings on the transmission shaft.
4, gear on the two transmission shaft centerline is not parallel, so that the two gears can not be correctly meshed work.
5、Poor lubrication conditions of the teeth of a pair of meshing gears, insufficient lubricating oil.
(4) plastic sheet machine barrel screw parts
1, the screw assembly in the machine Jane, two parts of low concentricity precision screw rotation and barrel inner circle to produce friction.
2, the barrel end face and barrel seat connection flange end face and barrel centerline verticality error is large.
3, the screw is bent and deformed, the straightness of the axis centerline error is too large.
4, the screw and its drive shaft assembly gap is too large work rotation of the two axis centerline different axis, the error is large.
