The previous article introduced several coupling alignment methods, and there are several alignment methods for reference below:
1) Single table alignment method
Use a dial indicator on the table wall with a piece of equipment to separately measure the axial offset of the two sections of the coupling, and the adjustment can be calculated graphically based on the reading on the dial indicator.It is also possible to carry out the radial and axial error values based on the measured axial offset value.
When measuring, the table frame must have sufficient bending rigidity, and its rigidity must be checked by strength.This kind of method does not need to measure the radial offset and eliminates the harm of radial shaking to the measurement precision. The longer the distance between the inner holes of the coupling, the higher the measurement precision.This method is suitable for equipment centering of long universal joints.
2) Double table alignment method
Application of magnetic table base (or support frame) and2A dial indicator measures the axial and radial deviations of the two-section coupling, which is basically the same as the measurement method of the management center card-like feeler gauge. Two dial indicators are used to replace the measuring point screws. The equipment as the picture shows4Icon.When this method is used for testing, the axial and radial offset values of the coupling can be loaded together at a certain measuring point.
3)The key disadvantage is that for couplings with radial sloshing, the radial offset value of the inner hole during cranking will cause errors and omissions.Therefore, this type of measurement method is suitable for small and medium-sized equipment with the drive shaft supported by the roller bearing plate and the radial displacement angular momentum is relatively small, and the distance between the inner holes of the coupling is relatively short.In order to eliminate the errors and omissions of radial swaying, we also chose the three-meter measurement method and the five-meter measurement method to carry out coupling alignment.
Using a dial indicator to measure the centering, the operator requires a very complicated analysis and carry-over of the statistical data calculated by the measurement, to determine the adjustment amount of the transmission device, and the technical standard is high.The production equipment of the watch frame is different due to the different equipment.Therefore, it is relatively simple and wrong to use a dial indicator to center, and it is more difficult for the protection personnel of machinery and equipment to apply.
4)Laser alignment tool alignment
Laser alignment instrument application multi-function support frame will1A low-output laser transmitter device is on the side of the device coupling, which will1A signal receiver device is on the other side of the coupling. After two particle beam replacements, the frame and dial indicator measure the axial offset of the two sections of the coupling to determine the error condition.The carry-over machine uses the change in the direction of the particle beam on the controller and the distance from the coupling management center to the signal receiver to carry over the equipment alignment status.
Now in daily industrial productionCoupling alignment of machinery and equipment is for maintenance of machinery and equipmentimportantjobs.OnIn actual operation, a suitable alignment method should be selected according to the specific situation.Nowadays, laser alignment instruments get rid of some of the shortcomings of the traditional coupling method, and the application in the maintenance of machinery and equipment has become more and more common.
