A rotor mounting assembly Technical Field

[0001] This utility model relates to the field of generator manufacturing technology, and in particular to a rotor mounting assembly. Background Technology

[0002] In the manufacturing and maintenance of equipment such as motors and generators, rotor installation is one of the core processes. Traditional rotor installation methods typically rely on large lifting equipment for direct hoisting, which presents the following problems: First, during hoisting, the rotor is prone to displacement or vibration due to uneven force or insufficient support, leading to damage to the stator windings or rotor components; second, installation accuracy depends on manual experience, resulting in low adjustment efficiency, especially difficult to operate in confined spaces; third, existing support structures are mostly fixed, making it difficult to adapt to the installation requirements of rotors of different sizes, resulting in poor reusability and increased costs. Furthermore, the lack of dedicated auxiliary devices for synchronous positioning of the lead-out and non-lead-out ends easily causes friction between the bearing retainer and the inner wall of the stator, affecting assembly quality.

[0003] In summary, a rotor mounting assembly is needed to address the shortcomings of the existing technology. Summary of the Invention

The jack is fixedly mounted on the top of the pad. Supports and a movable adjustment mechanism are respectively provided at the left and right ends of the stator. The pad and jack are fixedly installed between the supports and the stator. The supports are used to pull the rotor body, and the movable adjustment mechanism is used to support and assist in moving the rotor body. A pad, a sliding plate, and a journal bracket are detachably installed inside the stator. The sliding plate is located on the upper surface of the pad, and the journal bracket is movably mounted on the sliding plate. The journal bracket is used to adapt to and support the non-outgoing ends of the rotor body.

[0007] Furthermore, a support plate can be detachably installed inside the stator. The bottom of the support plate is movably connected to the slide plate, and the top wall of the support plate is used to fit and support the rotor body.

[0008] Furthermore, the rotor body is symmetrically provided with a retaining ring, blades and bearing stops at the output end and non-output end, and a slip ring is also provided on the output end of the rotor body.

[0009] Furthermore, the slip ring is mounted on a bearing stop on the output end side of the rotor body.

[0010] Furthermore, the movable adjustment mechanism also includes a cable tray, which is used to support the bearing stop on the side of the rotor body near the cable outlet.

[0011] The beneficial effects of this utility model are:

[0024] Example 1:

[0025] As shown in Figures 1-4, a rotor mounting assembly includes a stator 10, a rotor body 20, a pad 50, and a jack 60. The jack 60 is fixedly mounted on the top of the pad 50. The left and right ends of the stator 10 are respectively provided with a support 30 and a moving adjustment mechanism 40. The pad 50 and the jack 60 are fixedly installed between the support 30 and the stator 10. The support 30 is used to pull the rotor body 20, and the moving adjustment mechanism 40 is used to support and assist in moving the rotor body 20. The stator 10 has a detachable pad 11, a sliding plate 12, and a journal bracket 13. The sliding plate 12 is located on the upper surface of the pad 11, and the journal bracket 13 is movably mounted on the sliding plate 12. The journal bracket 13 is used to adapt and support the non-outgoing end of the rotor body 20.

[0026] In one implementation, a support plate 14 can also be detachably installed inside the stator 10. The bottom of the support plate 14 is movably connected to the slide plate 12, and the top wall of the support plate 14 is used to fit and support the rotor body 20.

[0027] In one embodiment, the rotor body 20 is symmetrically provided with a retaining ring 21, a blade 22 and a bearing stop 23 at the output end and the non-output end. The output end of the rotor body 20 is also provided with a collector ring 24. A lifting eye screw is fixed on the side wall of the bearing stop 23 away from the retaining ring 21. The lifting eye screw is connected to the support 30 by a traction rope.

[0028] In one embodiment, the slip ring 24 is mounted on the bearing stop 23 on the output end side of the rotor body 20.

[0029] In one embodiment, the movable adjustment mechanism 40 includes a ground rail 41, a trolley body 42, and a body bracket 43a. The trolley body 42 is movably connected to the ground rail 41, and the body bracket 43a is used to support the rotor body 20.

[0030] In one embodiment, the movable adjustment mechanism 40 also includes a cable tray 43b, which supports the bearing stop 23 on the side of the rotor body 20 near the cable outlet.

[0031] In one embodiment, a lifting rod 15, a hand-operated hoist 16, and a lower end cover 17 for the output terminal are installed on the upper side wall of the stator 10 near the output terminal. The lifting rod 15 is connected to the lower end cover 17 for the output terminal via the hand-operated hoist 16. The lower end cover 17 for the output terminal is used to assist in supporting and lifting the rotor body 20, thereby facilitating the replacement of the body bracket 43a with the output bracket 43b. The output bracket 43b supports the bearing stop 23 near the output terminal of the stator 10.

[0032] The working principle of this utility model is as follows: First, a journal bracket 13 is installed inside the stator 10, and a body bracket 43a is installed on the trolley body 42. The body bracket 43a supports the bottom outer wall of the rotor body 20. The bearing stop 23 at one end of the left side of the rotor body 20 is supported by the journal bracket 13. The bearing stop 23 on the side of the rotor body 20 closest to the journal bracket 13 is connected to the support 30 via a lifting eye screw and a traction rope. The traction rope slowly pulls the generator rotor forward by 1 / 3 of its position within the stator. At this point, an extension rod is installed at the end of the bearing stop 23 and fixed to the jack 60. Then, the journal bracket 13 can be removed. The rotor body 20 is then fitted into the support plate 14 and placed against the bottom wall of the rotor body 20. The inner circle of the stator core 10 is protected by the pad 11, the slide plate 12, and the support plate 14. After it is in place, the rotor body 20 is lifted by the hoist 15, the hand chain hoist 16, and the lower end cover 17 of the output terminal in conjunction with auxiliary support. The bearing stop 23 on the side of the output terminal of the rotor body 20 is then lifted, which makes it easier to replace the body bracket 43a on the trolley body 42 with the output bracket 43b. The output bracket 43b supports the bearing stop 23 on the side of the output terminal of the stator 10. The jack 60 is lowered, and the generator rotor is dragged to the installation position by the traction rope. Finally, the trolley body 42 can be removed, and the jack 60 can be used for local fine-tuning.

[0033] Example 2:

[0034] As shown in Figure 5, this embodiment is basically the same as embodiment 1, except that the trolley body 42 is provided with a hydraulic lifting mechanism for adjusting the height of the cable tray 421. The hydraulic lifting mechanism can be used to quickly detach the trolley body 42 after lowering the height of the body tray 43a, so that the cable tray 43b can be replaced and installed. Then the cable tray 43b can support the bearing stop 23 at the right end of the rotor.

[0035] It should be noted that while the preferred embodiments of this utility model are provided in the specification and accompanying drawings, this utility model can be implemented in many different forms and is not limited to the embodiments described in this specification. These embodiments are not intended to impose additional limitations on the content of this utility model; their purpose is to provide a more thorough and comprehensive understanding of the disclosure of this utility model. Furthermore, the above-mentioned technical features can be combined with each other to form various embodiments not listed above, all of which are considered to be within the scope of this utility model specification.
