Description

Technical Field

[0001] The utility model relates to the technical field of bearings, in particular to a machine tool spindle bearing with a temperature monitoring function. Background Art

[0002] The machine tool spindle bearing is the spindle bearing of precision machine tools and similar equipment. It is an important component in contemporary mechanical equipment to ensure the working accuracy and performance of precision machine tools. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. When the bearing is running at high speed, the friction will not only increase energy consumption, but also cause the temperature of the bearing surface to rise. What is more terrible is that it is easy to damage the bearing. Traditional bearings do not have temperature detection function and cannot determine the temperature change of the surface when the bearing rotates. For this reason, we designed a machine tool spindle bearing with temperature monitoring function to solve the above technical problems. Utility Model Content
