Abstract

The invention relates to a wireless passive temperature detection device for a bearing, a bearing assembly and a roller assembly. The invention provides a temperature detection device for a bearing, and the device comprises a detection head which comprises an inner surface and an outer surface which is in contact with the bearing; a temperature detection chip configured to be in contact with an inner surface of the detection head for detecting a temperature by the detection head; a cable; the antenna is detachably connected with the temperature detection chip through a cable, and the antenna is configured to be capable of wirelessly obtaining electric energy from the outside, transmitting the electric energy to the temperature detection chip through the cable and wirelessly sending a temperature signal received from the temperature detection chip through the cable to external equipment.

Description

technical field [0001] The present invention relates to the technical field of bearings. More specifically, the present invention relates to the technical field of bearing temperature detection. Background technique [0002] In the cold rolling production line of the iron and steel industry, in order to ensure the quality of the cold rolled steel coil, the backup rolls of some rolling mills are lubricated with oil and gas, so the working temperature of the bearings is very high. At the same time, in order to improve production efficiency, the backup rolls, intermediate rolls and work rolls of the rolling mill often run at high speed. At this time, the bearings used for each roll are at high temperature. The high temperature of the bearings may cause the bearings to lock up, resulting in serious losses. . For this reason, it is necessary to measure the bearing temperature of cold-rolled backup rolls. In addition, due to the harsh working environment and frequent replacemen...
