[0042] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the present embodiment provides a walking beam machine direct-drive motor, comprising a motor flange base 100, an inner stator 200, an outer rotor 300, a reduction shaft connecting seat 400 and a motor housing 500; a stator and rotor mounting seat 110 is arranged on the motor flange base 100, and the reduction shaft connecting seat 400 is adjustably arranged on the stator and rotor mounting seat 110; the inner stator 200 is arranged on the outer ring of the stator and rotor mounting seat 110, and the outer rotor 300 is connected to the reduction shaft connecting seat 400 through a rotor adapter plate 310, and the outer rotor 300 is located on the outer periphery of the inner stator 200; a sealing seat 120 for carrying the walking beam machine output shaft 600 is arranged on the motor flange base 100, and one end of the walking beam machine output shaft 600 can pass through the sealing seat 120 to be connected to the reduction shaft connecting seat 400; the motor housing 500 is arranged on the motor flange base 100.

[0043] Specifically, when using the walking beam machine direct-drive motor, the staff inserts the walking beam machine output shaft 600 into the motor flange base 100, and the walking beam machine output shaft 600 passes through the sealing seat 120 on the motor flange base 100, and then the walking beam machine output shaft 600 is fixed on the reduction shaft connecting seat 400.

Through such an arrangement, the walking beam machine direct-drive motor can be directly installed on the reducer of the walking beam machine without the need for a transmission structure, thereby improving the motor efficiency.

[0044] The sealing seat 120 is detachably arranged in the middle of the motor flange base 100 .

[0046] It should be pointed out that the sealing seat 120 is located at the outer end of the motor flange base 100 and is provided with a positioning ring 121 that can be connected to the walking beam machine reducer. The walking beam machine direct drive motor can be directly installed on the reduction box of the walking beam machine, and the positioning ring 121 and the positioning structure of the reduction box are used for centering installation.

[0052] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in an optional scheme of this embodiment, the stator and rotor mounting seat 110 also includes an adjustment ring seat 113 for mounting the reduction shaft connecting seat 400, the adjustment ring seat 113 is mounted on the inner ring of the stator mounting seat 112, a plurality of adjustment mounting blocks 114 are arranged on the adjustment ring seat 113, and the adjustment mounting blocks 114 are provided with adjustment bolts 115, and the adjustment bolts 115 abut against the reduction shaft connecting seat 400.

[0053] Specifically, before the beam machine direct drive motor provided in this embodiment is installed on the reduction box of the beam machine, the axis of the reduction shaft connecting seat 400 can be adjusted by adjusting the adjusting bolt 115 on the adjusting ring seat 113, so that the reduction shaft connecting seat 400 can be smoothly connected with the beam machine reduction shaft. After the beam machine direct drive motor provided in this embodiment is installed, the adjusting bolt 115 is loosened, so that the reduction shaft connecting seat 400 can rotate with the outer rotor 300, and the beam machine reduction shaft can support the outer rotor 300.

A spare bearing is provided on the spare bearing seat 130, and the spare bearing is clearance-matched with the reduction shaft connecting seat 400. The spare bearing does not rotate during normal operation. Therefore, there is no need to consider the life of the bearing when there is no fault. When a fault occurs, the spare bearing can support the reduction shaft connecting seat 400, thereby preventing the outer rotor 300 from falling and preventing the outer rotor 300 from sweeping the bore.
