| 摘要 |
The present invention relates to a method for measuring waviness of surfaces, in particular waviness on bearing parts, such as balls, rollers and bearing rings using a control element being rotatably applicable against a surface of an object to be checked, whereby a loaded control element (6) having a contact area to the object and having a similar geometry around the contact as the object of the final bearing component is placed in a hydrostatic pocket (5), or kept in a bearing arrangement, allowing it to rotate and move freely; the element (6) is loaded with a substantially constant force; the element (6) is arranged to be moved rotatably across the surface (11) to be tested; at least one transducer (8, 13) is arranged to monitor the direct movement of the element (6) or the movement via the pocket (5); and a signal is created corresponding to the waviness occurred. The invention further relates to an apparatus for carrying out the method. <IMAGE> |
