1.
With a feeler and ruler to check when the equipment through the coupling and docking, should make two and a half day to achieve high alignment, namely axial line.
In addition, in order to prevent caused by a small amount of axial channeling move 'on top' two and a half day, should keep the docking two section plane 2 ~ 3 mm gap, precise, feeler available for testing.
Available, alignment is a ruler is straight or side plate, board to wait on the coupling side, on the top surface and two side for inspection, if the two and a half day and the ruler are closed, then coaxial degree meet the requirements, otherwise there is parallel to the axial axial parallel phenomenon, but not overlap or as shown in the figure below.
2.
With a dial indicator check half section of the alignment error in section two and a half without coupling, a dial indicator through magnetic table frame fixed on the side of the coupling.
Table measuring head pressure on the load side of the side of the coupling.
Will adjust after the dial indicator, dynamic coupling for a week, as shown in the figure below.
Record the variation of dial indicator indicating (
The difference between the maximum and minimum values)
。
The change in the two and a half section of the alignment error, commonly known as 'beat circle'.
According to the accuracy requirement of the equipment used (
If the requirements of the overall vibration)
And the type of coupling (
Rigid connection or flexible connection)
, its control within a proper range, such as 0.
05mm。
