A device for error diagnosis of low-speed bearings

摘要

A device for error diagnosis of low-speed rolling bearings consisting of the frame (5) which accommodates the shaft (1) on which there are arranged the diagnosed shaft bearings (2), which are located in the reference member (3) which is rotatably placed in the bearings (4) relative to the frame (5), while the reference member (3) is connected to the position sensor (6) coupled to the frame (5) by means of which the damage to bearings (2, 4) is signalized at an early stage. In an alternative embodiment, the reference member (3) is connected to the alternative drive (7) with higher, pre-defined revolutions than the revolutions of the shaft (1), when measuring the vibrations induced on the frame (5) in the vicinity of the bearings (2, 4) can detect the defined amplitude of the frequency spectrum indicating the state of damage to the bearings (2, 4).
