Abstract

Systems, methods, and devices are provided for aligning a reference axis of an accelerometer with a measurement axis of a machinery component. An adaptor including a mounting plate, a plate stud integrated within the mounting plate, and a screw can be coupled to an accelerometer to ensure proper alignment of the reference axis of the accelerometer with the measurement axis of the machinery component. Aligning the reference axis and the measurement axis using the adaptor ensures that the axial orientation of the vibration data collected by the accelerometer properly corresponds to the intended axis of measurement of the machinery component and thus allows for consistent, repeatable installations of the accelerometer onto the machinery component without introducing alignment errors which can generate erroneous vibration data with respect to one or more axes of measurement.

Claims (33)

1. An adaptor comprising:

a mounting plate configured to couple an accelerometer to a machinery component, the mounting plate including a first surface and a second surface, the second surface opposite the first surface, and a plate stud integrated with the mounting plate at the second surface;

a collar arranged with respect to a periphery of the mounting plate and extending vertically away from the first surface of the mounting plate at which the accelerometer is coupled to the mounting plate so as to surround a portion of the accelerometer; and

a screw, including a screw head, the screw configured to couple the accelerometer to the mounting plate such that a reference axis indicator of the accelerometer is aligned with a measurement axis indicator applied to the mounting plate.

2. The adaptor of claim 1 , wherein the mounting plate is shaped as a circle, an oval, a rectangle, a square, a triangle, a polygon, or a parallelogram.

3. The adaptor of claim 1 , wherein the collar includes a plurality of vertical surfaces arranged around the periphery of the mounting plate.

4. The adaptor of claim 1 , wherein the plate stud includes a first screw thread configuration corresponding to a first outer diameter of the plate stud or a second screw thread configuration corresponding a second outer diameter of the plate stud.

5. The adaptor of claim 1 , wherein the plate stud extends away from the second surface of the mounting plate and includes a bore extending through the plate stud, the bore including a first opening in the first surface of the mounting plate and a second opening opposite the second surface of the mounting plate, the bore allowing the screw to pass through the plate stud and the mounting plate to couple the accelerometer to the mounting plate.

6. The adaptor of claim 5 , wherein the second opening of the bore is configured to receive the screw head within a recess formed within the second opening of the bore or to receive the screw head such that the screw head is directly interfaced with the second opening of the plate stud.

7. A system comprising:

an adaptor configured to couple an accelerometer to a machinery component, the adaptor including,

a mounting plate including a first surface and a second surface, the second surface opposite the first surface, and a plate stud integrated with the mounting plate at the second surface;

a collar arranged with respect to a periphery of the mounting plate and extending vertically away from the first surface of the mounting plate at which the accelerometer is coupled to the mounting plate so as to surround a portion of the accelerometer; and

a screw, including a screw head; and

an accelerometer coupled to the mounting plate via the screw such that a reference axis indicator of the accelerometer is aligned with a measurement axis indicator applied to the mounting plate, the accelerometer configured to measure vibration data associated with a machinery component.

8. The system of claim 7 , wherein the mounting plate is shaped as a circle, an oval, a rectangle, a square, a triangle, a polygon, or a parallelogram.

9. The system of claim 7 , wherein the collar includes a plurality of vertical surfaces arranged around the periphery of the mounting plate.

10. The system of claim 7 , wherein the plate stud includes a first screw thread configuration corresponding to a first outer diameter of the plate stud or a second screw thread configuration corresponding a second outer diameter of the plate stud.

11. The system of claim 7 , wherein the plate stud extends away from the second surface of the mounting plate and includes a bore extending through the plate stud, the bore including a first opening in the first surface of the mounting plate and a second opening opposite the second surface of the mounting plate, the bore allowing the screw to pass through the plate stud and the mounting plate to couple the accelerometer to the mounting plate.

12. The system of claim 11 , wherein the second opening of the bore is configured to receive the screw head within a recess formed within the second opening of the bore or to receive the screw head such that the screw head is directly interfaced with the second opening of the plate stud.

13. A method comprising:

positioning an adaptor with respect to a machine, the adaptor configured to couple an accelerometer to the machine, wherein the adaptor includes a mounting plate, a screw, and a collar arranged with respect to a periphery of the mounting plate and extending vertically away from the first surface of the mounting plate at which the accelerometer is coupled to the mounting plate so as to surround a portion of the accelerometer;

securing the adaptor with respect to the machine;

determining a measurement axis of a machinery component of the machine;

applying an indicator of the measurement axis on the mounting plate;

removing the adaptor from the machine;

coupling the accelerometer to the adaptor so as to align a reference axis indicator of the accelerometer with the measurement axis indicator on the mounting plate; and

securing the adaptor, including the coupled accelerometer, with respect to the machine.

14. The method of claim 13 , wherein securing the adaptor with respect to the machine includes applying a predetermined amount of torque to the mounting plate.

15. The method of claim 13 , wherein the accelerometer includes a single-axis accelerometer, a dual-axis accelerometer, a triaxial accelerometer, a velocity vibration transducer, or a displacement vibration transducer.

16. The method of claim 13 , wherein applying a measurement axis indicator includes applying the measurement axis indicator on the mounting plate with a marker or sharp object, the measurement axis indicator corresponding to the determined measurement axis of the machinery component.

17. The method of claim 13 , further comprising operating the machinery component and collecting vibration data via the accelerometer.

18. The method of claim 13 , wherein the accelerometer is coupled within the adaptor by inserting the screw through a plate stud integrated with the mounting plate and tightening the screw in the accelerometer with a predetermine amount of torque.
