Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of multi-drive equipment, and in particular to a drive part of a multi-flange motor drive system. Background Art
[0002] In order to ensure that the load can work continuously, at least two sets of power drive motors are sometimes connected to the load to avoid the problem that the load stops working after a set of drive motors fails. However, the maintenance or replacement of the drive motor must be carried out when the load is shut down, so that the running motor has no backup motor, which poses a safety hazard and ultimately affects the continuous operation of the load. Some loads are driven by flange motors, and the motor is directly installed on the load through the flange. Summary of the invention
[0003] The purpose of the present invention is to solve the problem that the existing multi-drive equipment needs to be shut down for maintenance and replacement of the drive motor, and to provide a device with a simple structure and convenient replacement of flange drive motors.

[0006] It also includes flange B, pin B, and shell B, which have the same structure as flange A, pin A, and shell A and are installed on the load shaft B side of the load; the flange B is installed on the end face of shell B; one end of the pin B is fixed on shell B, and the other end passes through flange B and is parallel to the central axis of flange B; the flange B can be axially moved along the pin B to be separated or combined with shell B; the flange-type motor B is fixed on flange B, the motor shaft B passes through the central hole of flange B and extends into shell B, and a conductor rotor B is arranged on the motor shaft B; the shell B is fixed on the load, the load shaft B passes through the central hole of shell B and extends into shell B, and a permanent magnet rotor B is arranged on the load shaft B; the conductor rotor B is concentrically sleeved with the permanent magnet rotor B.
[0007] When in use, flange motor A drives conductor rotor A to rotate, conductor rotor A drives permanent magnet rotor A to rotate through magnetic field, and permanent magnet rotor A drives load to rotate; when flange motor A fails, flange motor B is started, flange motor B drives conductor rotor B to rotate, conductor rotor B drives permanent magnet rotor B to rotate through magnetic field, and permanent magnet rotor B drives load to rotate; while the load continues to run, flange A is moved away from housing A along pin shaft A, flange motor A and conductor rotor A are removed together, flange motor A is replaced or repaired, and after troubleshooting, flange motor A is fixed on flange A, conductor rotor A is fixed on motor shaft A of flange motor A, flange A is moved along pin shaft A to be recombined with housing A, and flange motor A is put back into operation; similarly, when flange motor B fails, operation can be switched to flange motor A, and flange motor B can be replaced or repaired without stopping the machine.
[0008] The number of the pins A and the number of the pins B are no less than 2.
[0009] A linear bearing A is arranged on the surface of the flange A in contact with the pin shaft A, and a linear bearing B is arranged on the surface of the flange B in contact with the pin shaft B.
[0010] The conductor rotor A, the permanent magnet rotor A, the conductor rotor B and the permanent magnet rotor B are all cylindrical structures.
[0011] The pin A can also have one end fixed on flange A and the other end passing through shell A, and flange A drives the pin A to move axially relative to shell A; the pin B can also have one end fixed on flange B and the other end passing through shell B, and flange B drives the pin B to move axially relative to shell B.
[0012] Compared with the prior art, the present invention has the following advantages:
[0013] The non-stop maintenance device for a system driven by multiple flange-type motors of the present invention utilizes the coupling of the magnetic field between the conductor rotor and the permanent magnet cylinder to transmit power, and at the same time utilizes the characteristic of no mechanical connection between the conductor rotors to disconnect the power transmission between the motor and the load, so that the motor can be repaired, replaced and installed without stopping the load. The flange and pin shaft structure is more suitable for the disassembly and assembly of flange-type motors. The installed drive motor can be used as a backup machine for the running motor to ensure the continuous operation of the load, reduce the number of drive motors, have a simple structure, and simplify the structure and investment cost of the system.
