Integrated coupling type intelligent monitoring bearing

Abstract

The invention discloses an integrated coupling type intelligent monitoring bearing, which comprises a bearing (1) and an intelligent monitor (2) which is arranged on the bearing (1), the bearing (1) comprises an immovable outer ring (3) and a rotatable inner ring (4), a rolling ball (5) or a rolling post (5') is arranged between the immovable outer ring (3) and the rotatable inner ring (4), the intelligent monitor (2) comprises a shell body (6) and a rotational speed code disc (7) which is a round code disc which is arranged in the shell body (6) and has the same axial core as the shell body (6), the intelligent monitor (2) is arranged at one side of the bearing (1), and the intelligent monitoring bearing has the beneficial effects of detecting fault information of the bearing at short distance under the premise of not damaging the structure of the bearing and relatively actually obtaining the operating acceleration, rotational speed and temperature of the bearing without damaging the structure of the bearing and causing the problem of stress concentration of the bearing.

Description

technical field [0001] The invention belongs to bearings, in particular to a novel integrated coupling intelligent monitoring bearing applied to bearing state detection. Background technique [0002] The current integrated smart bearings have two structural forms: external and embedded. The external combination method does not destroy the structure of the bearing but changes the overall size of the traditional bearing. At the same time, the characteristics of this type of combination determine that there is a certain distance between the sensing component and the source of the fault, so that the acquired signal cannot truly reflect the bearing. This method cannot be used for early detection of bearing fault characteristics, because the bearing fault detection with this structure cannot guarantee the reliability of the signal; the embedded combination method is very close to the source of the measured signal, and the signal The intermediate interface of transmission is reduc...

Problems solved by technology

The external combination method does not destroy the structure of the bearing but changes the overall size of the traditional bearing. At the same time, the characteristics of this type of combination determine that there is a certain distance between the sensing component and the source of the fault, so that the acquired signal cannot truly reflect the bearing. This method cannot be used for early detection of bearing fault characteristics, because the bearing fault detection with this structure cannot guarantee the reliability of the signal; the embedded combination method is very close to the source of the measured signal, and the signal The intermediate interface of transmission is reduced, the collected signal can truly reflect the actual working condition of the bearing, and the signal-to-noise ratio is high, but this structure destroys the integrity of the bearing, and it is easy to cause problems such as stress concentration, so this structure is also important for bearing state detection. there are certain problems

[0003] The disadvantages of the existing technology are: there is a certain distance between the external structure sensing component and the fault source, the obtained signal cannot truly reflect the fault information of the bearing, and the embedded structure destroys the internal structure of the bearing, causing the stress of the bearing concentration problem
