Description

Technical Field

[0001] The present invention relates to the field of rotors, and more specifically to a starter rotor for effectively positioning enameled wires. Background Art

[0002] In the operation system of large equipment, large starters play an indispensable role. In the field of large ships, the start of its engine relies on a large starter to provide strong power; on railway locomotives, the starter provides initial power for the engine or traction motor; in large mining machinery operations, the starter drives the mining machinery to start. Taking the ZQF-80G1 DC starter generator of railway locomotives as an example, its external dimensions reach 1033×670×690mm, which shows the huge size of such equipment.

[0003] However, when the starter rotor enters the maintenance and repair process, the L-shaped hooks on the rotor need to be pried open with tools during the repair process, especially when it comes to replacing or rewinding the enameled wires. This operation is extremely likely to cause deformation of the L-shaped hooks, resulting in poor positioning performance of the enameled wires after repair and easy occurrence of wire breakage during use. During repair, if the L-shaped hooks are re-fixed by welding, although the problem can be solved, the process is cumbersome and time-consuming; while directly replacing the entire commutator is not only costly but also complex in operation. Summary of the Invention

[0004] In view of the problems in the prior art, the present invention provides a starter rotor for effectively positioning enameled wires.

A second elastic member is arranged inside the support, and the second elastic member is used to push the sliding rod to reset. A pull wire is arranged on the sliding rod, and the end of the pull wire is connected to the extrusion component and moves along with the extrusion component.

[0009] Preferably, a wire hole is arranged inside the support, and the wire hole is used to guide the movement of the pull wire.

[0010] A release component is arranged on the support. When the release component slides and the end of the limiting rod is exposed, the limiting rod rotates around the rotating pin, and the enameled wire disengages from below the limiting rod.

[0011] Preferably, when the enameled wire is extruded on the extrusion component, the extrusion component drives the pull wire to move, driving the sliding rod and the limiting rod to extend outward from the inside of the support and be located above the enameled wire.

[0015] Preferably, a tension spring is arranged inside the hook, and the tension spring is used to pull the pulling rod.

[0016] The clamping component includes a groove wedge arranged inside the wire groove. The groove wedge is used to clamp the enameled wire.

Detailed implementation manners

[0032] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0033] In one embodiment, please refer to the attached Figure 1-11 As shown in the figure, a starter rotor for effectively positioning enameled wire according to the present invention includes a plurality of iron cores 1 attached together. A rotating shaft 2 penetrating through its interior is provided inside the iron core 1. A commutator 4 is provided on the rotating shaft 2, and the commutator 4 is located on one side of the iron core 1; a plurality of hooks 5 are provided on the commutator 4. A wire groove 11 is formed on the iron core 1, and enameled wire 3 is wound around the wire groove 11 and the hooks 5; a limiting component 8 is provided on the hook 5, and the limiting component 8 restricts the wound enameled wire 3 on the hook 5. A clamping component 6 is provided on the iron core 1, and the clamping component 6 positions the enameled wire 3 in the wire groove 11.

[0034] In order to facilitate the positioning and maintenance of the wound enameled wire 3, the installed enameled wire 3 is positioned through the provided limiting component 8 to prevent the enameled wire 3 from breaking when the commutator 4 and the iron core 1 rotate; through the provided clamping component 6, the enameled wire 3 can be clamped inside the wire groove 11 to position the enameled wire 3 inside the wire groove 11, so that during the maintenance and repair process, the enameled wire 3 can be positioned more conveniently.

[0035] In another embodiment, please refer to the attached Figure 1-8 As shown in the figure, further, an extrusion component 9 is further provided on the hook 5. When the enameled wire 3 is pressed against the extrusion component 9, the extrusion component 9 pulls the limiting component 8 to move until the limiting component 8 moves above the enameled wire 3 to limit the enameled wire 3; a release component 7 is provided on the limiting component 8, and the release component 7 is used to release the limit on the limiting component 8.

[0036] In order to position the enameled wire 3 during winding; since the enameled wire 3 enters the hook 5 at an inclined angle, the enameled wire 3 presses on the extrusion assembly 9, the extrusion assembly 9 moves and pulls the limit assembly 8 to move, and the limit assembly 8 extends forward from the side wall of the hook 5 until the limit assembly 8 just abuts above the enameled wire 3, so that the limit assembly 8 positions the enameled wire 3; the pressure generated during the winding of the enameled wire 3 pushes the limit assembly 8 to move and position the enameled wire 3; when it is necessary to disassemble the limit assembly 8, the limit assembly 8 is released by the release assembly 7. Subsequently, the limit assembly 8 resets. After the limit assembly 8 resets, the enameled wire 3 moves out from one side of the limit assembly 8. Also, because the enameled wire 3 enters the hook 5 at an inclined angle, the reset process of the limit assembly 8 will not interfere with the enameled wire 3; it is convenient to position and remove the enameled wire 3, making the winding and disassembly of the enameled wire 3 more convenient.

[0037] In one embodiment, please refer to the attached drawings of the specification Figure 1 and 3 -8, the limit assembly 8 includes a support 82 provided on the hook 5, a limit rod 81 is provided on the support 82, a slide rod 83 is provided on the support 82, both the limit rod 81 and the slide rod 83 slide on the support 82, the slide rod 83 is rotatably connected to the limit rod 81, and the slide rod 83 and the limit rod 81 are connected by a pivot pin 84; a plurality of slots 87 are provided on the slide rod 83, and the slots 87 are inserted into the release assembly 7; a second elastic member 85 is provided inside the support 82, and the second elastic member 85 is used to push the slide rod 83 to reset. A pull wire 86 is provided on the slide rod 83, and the end of the pull wire 86 is connected to the extrusion assembly 9 and moves with the extrusion assembly 9; a wire hole is provided inside the support 82, and the wire hole is used to guide the movement of the pull wire 86.

[0038] The release assembly 7 is provided on the support 82. When the release assembly 7 slides and the end of the limit rod 81 is exposed, the limit rod 81 rotates around the pivot pin 84, and the enameled wire 3 disengages from below the limit rod 81; when the enameled wire 3 presses on the extrusion assembly 9, the extrusion assembly 9 drives the pull wire 86 to move, driving the slide rod 83 and the limit rod 81 to extend outward from the inside of the support 82 and be located above the enameled wire 3.

[0039] When the limit component 8 needs to be limited, when the extrusion component 9 is extruded by the enameled wire 3, the extrusion component 9 pulls the wire 86. The wire 86 slides inside the wire hole. Due to the existence of the wire hole, the wire 86 during the movement can be in a taut state, and the wire 86 is always guided by the wire hole during movement. The wire 86 can pull the sliding rod 83 to move, and the movement of the sliding rod 83 drives the limit rod 81 to move. Until the extrusion component 9 moves to the maximum position, the rotating pin 84 moves out of the inside of the support 82 along with the limit rod 81 and is located below the release component 7. The limit rod 81 just moves above the enameled wire 3. Refer to the attached Figure 6 As shown in the figure, the ends of the limit rod 81 and the sliding rod 83 are in contact with each other, and the limit rod 81 is limited and cannot be turned downward, realizing the positioning of the enameled wire 3; when the enameled wire 3 needs to be removed, the release component 7 moves to make the rotating pin 84 move out from below the release component 7, releasing the limit rod 81. When the enameled wire 3 moves upward, the enameled wire 3 will push the limit rod 81 to rotate around the rotating pin 84; the enameled wire 3 is no longer restricted by the limit rod 81, and the enameled wire 3 moves out of the inside of the hook 5, making the disassembly process more convenient when the enameled wire 3 is disassembled.

[0040] In one embodiment, please continue to refer to the attached Figure 3-8 As shown in the figure, the extrusion component 9 includes an extrusion block 91 arranged on the hook 5. The extrusion block 91 is extruded by the enameled wire 3 and moves. An opening groove 92 is formed on the side wall of the extrusion block 91 for the wire 86 to move; a receiving groove 95 is formed on the hook 5 for receiving the extrusion block 91. A third elastic member 94 is arranged inside the hook 5 to push the extrusion block 91 to reset; a guiding rod 93 is arranged on the extrusion block 91 and slides inside the hook 5.

[0041] In order to make the extrusion block 91 drive the opening groove 92 to move when the enameled wire 3 contacts the extrusion block 91, the opening groove 92 provides enough space for the wire 86 during movement, so that the wire 86 will not be damaged by extrusion during movement; the guiding rod 93 is provided to guide the movement of the extrusion block 91, facilitating the extrusion block 91 to move along the direction of the guiding rod 93 when being extruded until the extrusion block 91 is pressed to the maximum position by the enameled wire 3; when the enameled wire 3 is wound, the extrusion block 91 drives the wire 86 to pull the sliding rod 83 and the limit rod 81 to move until the limit rod 81 positions the enameled wire 3.

[0042] In one embodiment, please continue to refer to the attached Figure 3-8As shown, the release component 7 includes a stop lever 71 disposed on the support 82. The stop lever 71 slides on the support 82. A pull lever 72 is disposed on the stop lever 71, and a plug lever 73 is disposed on the pull lever 72. The plug lever 73 is inserted into the jack; a tension spring is disposed inside the hook 5, and the tension spring is used to pull the pull lever 72.

[0043] To provide a more convenient operation when disassembling the enameled wire 3, pull the pull lever 72. The pull lever 72 is separated from the stop lever 71. The stop lever 71 can slide on the support 82. When the stop lever 71 contracts from the pivot pin 84, the stop lever 71 cannot limit the limit lever 81. When the enameled wire 3 moves upward, the limit lever 81 rotates around the pivot pin 84, so as to achieve the effect of rapid disassembly. Further, through the insertion of the plug lever 73 and the jack, the moved slide bar 83 will not move due to the action of the second elastic member 85, and thus the positions of the slide bar 83 and the limit lever 81 can be stabilized; after pulling the pull lever 72, the stop lever 71 moves and the limit lever 81 is not limited. At this time, the enameled wire 3 presses on the extrusion block 91, the extrusion block 91 pulls the wire 86, and the wire 86 pulls the slide bar 83. The slide bar 83 will not move backward due to the action of the second elastic member 85 at this time; when the enameled wire 3 is separated from the extrusion block 91, the extrusion block 91 is reset under the action of the third elastic member 94. At this time, the second elastic member 85 pulls the slide bar 83 to move and drives the limit lever 81 to be received inside the support 82, which is convenient for the limit lever 81 to slide out from the inside of the support 82 and move above the enameled wire 3 when winding the enameled wire 3, so as to position the enameled wire 3, so that the positioning of the enameled wire 3 can be completed during the winding process of the enameled wire 3.

[0044] In another embodiment, please continue to refer to the attached drawings of the specification Figure 1 and 9 -11, the engaging component 6 includes a groove wedge 62 disposed inside the wire groove 11. The groove wedge 62 is used to clamp the enameled wire 3. A clamping plate 61 is disposed above the groove wedge 62. The clamping plate 61 is used to limit the movement of the groove wedge 62. A movable clamping block 63 is disposed on the clamping plate 61, and a first elastic member 64 is disposed on the clamping plate 61. A clamping hole is formed on the wire groove 11. The first elastic member 64 is used to push the clamping block 63 to move into the clamping hole.

[0045] The existing groove wedge 62 is generally an integral structure. The groove wedge 62 is mainly used to limit the enameled wire 3, so that the enameled wire 3 is clamped inside the wire groove 11, and the enameled wire 3 inside the wire groove 11 is pressed tightly, so as to realize the fixation of the enameled wire 3; since the groove wedge 62 will squeeze the surface of the enameled wire 3 during the installation process and there will be sliding friction during the installation process, it is easy to wear the surface of the enameled wire 3, and it is easy to have the situation of paint peeling off the enameled wire 3. The enameled wire 3 after maintenance will not be able to be used continuously.

[0046] During installation, first place the slot wedge 62 inside the slot 11 without allowing the slot wedge 62 to contact the enameled wire 3 during the placement process. When the two ends of the slot wedge 62 are aligned with the two ends of the iron core 1, press down on the slot wedge 62 so that the slot wedge 62 fits against the enameled wire 3. Subsequently, insert the clamping block 63 from one end of the slot 11 above the slot wedge 62, and press firmly on the slot wedge 62 during the installation process. After the clamping block 63 is inserted into the slot 11, friction will occur between the slot wedge 62 and the clamping plate 61 at this time. When the installation of the clamping plate 61 is completed, the first elastic member 64 is used to push the clamping block 63 to move into the clamping hole. The clamping block 63 is engaged with the clamping hole, and the slot wedge 62 will not have sliding friction with the enameled wire 3 either, thus effectively protecting the enameled wire 3 and positioning the enameled wire 3 inside the slot 11. When disassembling the slot wedge 62, only need to pull the clamping plate 61 to separate from the slot wedge 62, and the clamping block 63 disengages from the inside of the clamping hole.

[0047] When the present invention is in use, when winding the enameled wire 3, the enameled wire 3 enters the inside of the hook 5 from the opening of the hook 5, and the enameled wire 3 presses on the extrusion block 91 at a certain inclination angle. The extrusion block 91 moves and pulls the pull wire 86, and the guide rod 93 moves along with the movement of the extrusion block 91 until the extrusion block 91 is pressed to the maximum position by the enameled wire 3. At this time, the pull wire 86 pulls the sliding rod 83 to move, and the movement of the sliding rod 83 drives the limiting rod 81 to move. When the extrusion block 91 moves to the maximum position, the rotating pin 84 moves out of the inside of the support 82 along with the limiting rod 81 and is located below the stop rod 71. The limiting rod 81 just moves above the enameled wire 3, and the ends of the limiting rod 81 and the sliding rod 83 abut against each other. The limiting rod 81 is limited and cannot be turned downward, realizing the positioning of the enameled wire 3. During the installation of the slot wedge 62, first place the slot wedge 62 inside the slot 11 without allowing the slot wedge 62 to contact the enameled wire 3 during the placement process. When the two ends of the slot wedge 62 are aligned with the two ends of the iron core 1, press down on the slot wedge 62 so that the slot wedge 62 fits against the enameled wire 3. Subsequently, insert the clamping plate 61 from one end of the slot 11 above the slot wedge 62, and press firmly on the slot wedge 62 during the installation process. After the clamping plate 61 is inserted into the slot 11, friction will occur between the slot wedge 62 and the clamping block 63 at this time. When the installation of the clamping block 63 is completed, the slot wedge 62 will not have sliding friction with the enameled wire 3 either, thus effectively protecting the enameled wire 3 and positioning the enameled wire 3 inside the slot 11. When it is necessary to remove the enameled wire 3, pull the pull rod 72, and the pull rod 72 separates from the stop rod 71. The stop rod 71 can slide on the support 82. When the stop rod 71 retracts from the rotating pin 84, the stop rod 71 cannot limit the limiting rod 81. When the enameled wire 3 moves upward, the limiting rod 81 rotates around the rotating pin 84. When the enameled wire 3 separates from the extrusion block 91, the extrusion block 91 resets under the action of the third elastic member 94. At this time, the second elastic member 85 pulls the sliding rod 83 to move and drives the limiting rod 81 to be received inside the support 82.

[0048] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments, and the above embodiments and the descriptions in the specification only illustrate the principles of the present invention.
