Embodiment Construction

[0025] figure 1 There is a bearing housing 10 which is a continuously cast bearing covered with a metal plate 14 and equipped with a sensor module 12 according to the invention. The bore 16 of the housing 10 is configured to accommodate the outer ring of a continuously cast bearing which is monitored by a monitoring unit (not shown) according to the invention.

[0026] The sensor module 12 comprises an inner part 12a embedded in the main steel of the bearing housing 10 and an outer part 12b comprising an antenna 18 of a wireless transceiver 19 and a thermoelectric generator formed for harvesting energy from the local environment. Energy Harvesting Circuit 20.

[0027] figure 2 After removing the metal plate 14 figure 1 Detail drawing of the bearing housing. The groove 21 on the upper surface of the bearing housing 10 connects the hole 22 accommodating the cylindrical inner part 12a, the outer part 12b and the guide cable 24 connecting the parts 12a, 12b, wherein the cable...

Abstract

The invention relates to a sensor module for monitoring bearings in steel industry applications comprising an embedded portion (12a) for being fitted into a hole (22) in a bearing component (10) of the bearing to be monitored, wherein the embedded portion (12a) comprises at least one sensor (34a, 34b, 36, 38). It is proposed that the embedded portion (12a) further comprises a clamping mechanism (30) generating clamping force acting on at least two opposing lateral internal faces of the hole (22).

Description

technical field [0001] The present invention relates to sensor modules for use in continuous casting bearings, and to condition monitoring and / or process control systems for use in the steel industry. Background technique [0002] The environment in steel production facilities is extremely harsh, with high temperatures, large amounts of water and high shock loads. It has traditionally been difficult to monitor all aspects related to the bearing process where equipment is exposed to the environment. [0003] Since bearings are subject to damage and unpredictable failure, there is a need for condition monitoring of continuously cast bearings or other bearings in the steel industry. However, condition monitoring is rarely used in this application due to the difficulty of access and wiring in harsh operating environments. Human access is impossible while the equipment is in operation, and high temperatures and high radiant heat flux make wiring difficult. To further complicat...
