Embodiment 1

[0034] The outer rotor motor bearing of the present invention is a commercially available outer rotor motor bearing. The outer rotor motor bearing includes a first end cover, a second end cover, a stator, a rotor, an inner circlip and an outer circlip, and the two ends of the stator are connected to the first end respectively. The cover is connected with the second end cover, the first end cover is provided with a bearing chamber, the rotor is placed in the stator, the rotor includes cables and bearings, the cables are placed in the bearings, the rotor at the cable end penetrates into the stator, the cables pass through the bearing chamber, and the bearings There is an oil protection cover in the room, and the inner and outer retaining springs fix the oil protection cover.

[0035] Such as Figures 1 to 4 As shown, a method for replacing bearings of an outer rotor motor includes disassembly, detection and assembly, wherein the disassembly steps include:

[0036] Marking: Mark...

Embodiment 2

[0053] The difference between this embodiment and embodiment 1 is that the detection step includes:

[0054] Measurement: use the end cap depth gauge to measure the depth from the notch plane of the end cap to the plane of the bearing chamber; correction, when the bearing chamber is worn, perform turning correction or replacement on the lathe, otherwise, turning correction is not required.

Embodiment 3

[0056] The difference between this embodiment and Embodiment 1 is that the assembling steps include: assembling the rotor, assembling the rotor into the first end cover; assembling the stator, assembling the stator outside the rotor; assembling the second end cover, aligning the second end cover The seam of the cover and the seam of the stator are pressed.

Abstract

The invention discloses a method and device for replacing an external rotor motor bearing. The method comprises steps of disassembly, detection and assembly, wherein the step of disassembly comprises steps of marking, first disassembly, device applying, judgment and secondary disassembly. By the method, the problems of easy damage of a part, time consumption and high cost during the replacement and adjustment processes of the motor bearing are solved. The method also comprises the step of replacing an end cover protection device during the replacement process, the problems of cable damage and end cover deformation during end cover disassembly are prevented, the motor bearing is rapidly replaced, the cable is prevented from being damaged by press, and the working time of the motor is prolonged; with the adoption of the device, the external rotor motor bearing part is more in contact, the bearing is difficult to damage and deform, and a guarantee is provided for easy replacement of the motor bearing.

Description

technical field [0001] The invention relates to the technical field of outer rotor motor bearings, in particular to a method and device for replacing outer rotor motor bearings. Background technique [0002] The paper threading belt motor is a very important transmission device in the paper industry. In the papermaking production process, the paper threading belt motor is used to guide the paper web from one section to the next section when the paper machine re-threads after a paper break, and continues to the next production process. When the paper threading belt motor is abnormal, the paper web cannot be transferred to the next section, and the paper machine cannot be produced directly. It can be said that the paper threading belt motor plays an important role in connecting the past and the future. [0003] The paper threading belt motor installed online in the paper machine workshop has been running for many years since the paper machine was started in 2016, and the abn...
