1. The utility model provides an intelligent bearing with automatic protection and detection function which characterized in that:

  • the intelligent bearing with the automatic protection and detection functions comprises a bearing body (1), a magnetic ring assembly (2) and a magnetic sensing assembly (3);

    the bearing body (1) comprises an inner ring (11), a rolling element (12) and an outer ring (13);

    the magnetic ring assembly (2) is fixedly arranged on the left end face of the inner ring (11) in a matched manner;

    the magnetic sensing component (3) is matched and fixedly arranged on the left end face of the outer ring (13);

    the magnetic sensing assembly (3) comprises a positioning sleeve (31), a circuit board (32), a magnetic sensor (33) and a lead-out wire (34);

    the end face of the positioning sleeve (31) is provided with a stepped hole (311) which is small at the left and large at the right, the outer ring wall of the positioning sleeve (31) is radially provided with a lead hole (312) which penetrates through the stepped hole (311) to the inner ring wall of the positioning sleeve (31), the lead hole (312) is matched with the lead wire (34), and the lead hole (312) is in an open state at the right side of the positioning sleeve (31);

    the circuit board (32) and the magnetic sensor (33) are installed in the stepped hole (311) in a matching mode, the section of a small hole in the left side of the stepped hole (311) is matched with the section of the circuit board (32), and the section of the stepped hole (311) is perpendicular to the radial direction of the positioning sleeve;

    the magnetic sensor (33) is matched and arranged on one surface of the circuit board (32) opposite to the axis of the positioning sleeve (31), and the sensing surface (331) of the magnetic sensor (33) is opposite to the magnetized surface of the magnetic ring component (2) at intervals through the lead hole (312);

    the lead-out wire (34) penetrates through a lead hole (312) on the outer ring wall of the positioning sleeve (31) to be matched and connected with the circuit board (32);

    the positioning sleeve (31) is matched and bonded with the outer ring (13) through fixing glue, and the circuit board (32) is firmly bonded in the stepped hole (311) through filling insulating materials at the small hole at the left side of the stepped hole (311) of the positioning sleeve (31).
