Description

Technical Field

[0001] The utility model relates to the technical field of bearing maintenance, in particular to an auxiliary disassembly device which does not damage the bearing. Background Art

[0002] Bearings are an important part of mechanical equipment. Their main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. Bearings can be divided into two categories: rolling bearings and sliding bearings. Generator bearings in dry and windy areas are high-speed ball bearings. Their grease is easy to dry and deteriorate. In addition, fine sand particles can penetrate everywhere, which increases mechanical wear and greatly reduces the maintenance and replacement cycle of bearings.

[0003] The maintenance and replacement of bearings both require disassembly procedures. In the prior art, bearing disassembly is mostly done by directly pulling the bearing with a puller. When disassembling the bearing, since the bearing and the rotor armature fit very tightly, the puller is too thick to cut in, and after the puller foot is thinned, the pulling force is insufficient to pull out the bearing without damaging the puller. At the same time, directly pulling the bearing with the puller is likely to damage the ball bearing. Therefore, a tool for assisting the disassembly of the bearing is urgently needed to achieve the effect of both protecting the bearing and assisting in the removal of the bearing. Utility Model Content

[0004] The purpose of the utility model is to overcome the defect that in the prior art, most of the bearings are disassembled directly by pulling the bearings with a puller. When disassembling the bearings, since the bearings and the rotor armature fit particularly tightly, the puller is too thick to cut in, and after the puller foot is thinned, the pulling force is insufficient to pull out the bearing without damaging the puller. At the same time, the bearing is easily damaged by pulling the bearing directly with the puller. An auxiliary disassembly device that does not damage the bearing is provided. By setting the device, when disassembling the bearing, the force of the puller will not act directly on the bearing, but on the semi-finished body, and then evenly distributed to the bearing through the bottom plate of the semi-finished body, so that the bearing can be avoided from being damaged due to local force.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

DETAILED DESCRIPTION

[0024] The following is combined with Figure 1 -Attached Figure 4 , further illustrating the specific implementation of the utility model of an auxiliary disassembly device that does not damage the bearing, which overcomes the problem in the prior art that most bearings are disassembled by directly pulling the bearing by a puller. When disassembling the bearing, the bearing and the rotor armature fit very tightly, and the puller is too thick to cut in. After the puller foot is thinned, its pulling force is not enough to pull out the bearing without damaging the puller. At the same time, directly pulling the bearing by a puller is prone to damage the ball bearing. By setting up this device, when disassembling the bearing, the force of the puller will not act directly on the bearing, but on the semi-finished body, and then evenly distributed to the bearing through the bottom plate of the semi-finished body, so as to avoid the situation where the bearing is damaged due to local force. The utility model of an auxiliary disassembly device that does not damage the bearing is not limited to the description of the following embodiments.

The bearing sleeve opening 109 can form a hollow structure in the middle of the bottom plate portion 103 after the two semi-finished bodies 1 are combined, so that the rotor armature can pass through.

[0027] By adopting the above technical solution:

[0028] When the device is in use, first, the two semi-completed bodies 1 are in a separated state, the bearing sleeves 109 in the two semi-completed bodies 1 are clamped on the rotor armature, and the semi-completed body 1 is slid so that the bottom plate portion 103 in the semi-completed body 1 slides to the bottom of the bearing, and then the two semi-completed bodies 1 are fixedly connected by connecting the studs 2, that is, the installation of the device is completed, and finally, the pulling tool is clamped on the outside of the arc sleeve portion 101, and the device is pulled until the bearing is disengaged, and the use of the device is completed. By setting up the device, when disassembling the bearing, the pulling force will not act directly on the bearing, but on the semi-completed body 1, and then evenly distributed to the bearing through the bottom plate portion 103 of the semi-completed body 1, so that the damage caused by local force on the bearing can be avoided.

A plurality of triangular reinforcement plates 106 are provided, and the plurality of triangular reinforcement plates 106 are distributed in a circular array. This can increase the strength of the eaves portion 102 on the semi-finished body 1 and improve its rigidity, so that the eaves portion 102 is not easily deformed during the process of removing the bearing of the pull code.

[0032] Furthermore, in order to improve the overall strength of the device, an eaves thickening portion 105 is welded or integrally formed at the structure of the triangular reinforcing plate 106 below the eaves portion 102 .

[0033] Furthermore, in order to improve the overall strength of the device, a bottom plate thickening portion 107 is welded or integrally formed below the edge of the bottom plate portion 103 .
