Condition monitoring for rollers

05 August 2019

Güdel has introduced condition monitoring for a set of industrial Internet of Things (IIoT) based products and tools, enabling customers to perform condition-based maintenance on smart Güdel products.

Güdel manufactures a wide range of products including linear guide-ways, racks, pinions and drives right through to linear axes and gantry robots.

Its components and modules are used within many industry segments, where high levels of efficiency and productivity are essential. A key element in attaining these objectives is the ability to reduce downtime.

Although only a small part of the linear tracks, robots, gantry systems and linear axes manufactured by the company, rollers play a significant part in the operation and reliability of these systems. Understanding the condition of the rollers is important if ongoing and trouble-free operation is to be achieved, and the new Condition Monitoring package from Güdel provides users with the data needed to predict potential component failure before it becomes a critical issue.

Güdel’s Condition Monitoring technology is based on the detection of vibration using accelerometers, a proven method to monitor the condition of ball bearings. The critical parts of a rolling bearing are those surfaces that run on each other. These are the rolling element surface, the running surface of the inner ring and the running surface of the outer ring. 

Should the running surfaces be damaged locally, a shock pulse occurs when the damaged area rolls over. This characteristic can be picked up by an accelerometer and the greater the damage, the stronger the shock pulse. In addition, as the speed of the roller is known, it is possible to determine whether the inner ring, outer ring or rolling element is defective.

The data collected from the sensors is stored on a local condition-monitoring computer, supplied as part of the package. No network connection is required and the Gu¨del Condition Manager software, installed on this local computer, allows users to manage the system. Options are available if required, should users wish to connect the system to a local network or the wider web and enable e-mail alerts etc. if the system detects a significant change in the pulses being picked up by the sensors.
