Publication number: 20180003492Abstract: The present invention resides in a sensorized roller of a roller bearing. The sensorized roller includes a roller bore that accommodates a measuring device for measuring deformation of the roller bore and electronics for processing a deformation signal from the measuring device and wirelessly transmitting the processed deformation signal to an external receiver. According to the invention, the measuring device and electronics are mounted in a rigid housing that is shaped to fit within the roller bore. A radially outer surface of the housing includes at least one aperture associated with the measuring device. Furthermore, the rigid housing is resiliently mounted to the roller bore via first and second sealing elements that enclose a radial gap between a radially inner surface of the roller bore and a radially outer surface of the housing.Type: ApplicationFiled: June 21, 2017Publication date: January 4, 2018Inventors: Andreas Clemens van der Ham, Nicolaas Simon Willem Den Haak, Gerrit-Jan Dop, Feng Qiu, Jeroen van Diermen

Patent number: 9851278Abstract: A bearing monitoring apparatus including at least one interface for receiving strain signals detected by at least one strain sensor mounted on a bearing and at least one data processing unit configured to monitor the bearing by detecting bearing defects based on the strain signals is provided. The data processing unit is configured to subject the strain signal to a high pass filtering. A limit frequency of the high pass filter is set higher than a typical ball pass frequency of the bearing to be monitored, to calculate a quantity representative of the amplitude of the envelope signal of the high-pass filtered strain signal, to compare the peak hold of the envelope signal with an envelope threshold value, to classify the bearing using the result of the envelope comparison and to issue at least one warning signal if the bearing is classified as defective.Type: GrantFiled: November 25, 2013Date of Patent: December 26, 2017Assignee: AKTIEBOLAGET SKFInventors: Andreas Clemens van der Ham, Nicolaas Simon Willem Den, Adam V. C. Reedman
