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; in 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, showing 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 the replacement or rewinding of 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 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

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

[0010] A release component is arranged on the support seat. 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 seat and be located above the enameled wire.

Detailed Embodiments

[0022] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0023] In one embodiment, please refer to the attached drawings of the specification Figure 1-11 As shown, a starter rotor for effectively positioning an enameled wire according to the present invention includes a plurality of iron cores 1 attached together. A rotating shaft 2 penetrating through the interior thereof 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 an 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.

[0024] For facilitating the positioning and maintenance of the wound enameled wire 3, the installed enameled wire 3 is positioned by the provided limiting component 8 to prevent the problem of wire breakage of the enameled wire 3 when the commutator 4 and the iron core 1 rotate; the provided clamping component 6 can clamp the enameled wire 3 inside the wire groove 11 to position the enameled wire 3 inside the wire groove 11, so that during the process of maintenance and repair, the enameled wire 3 can be positioned more conveniently.

[0025] In another embodiment, please refer to the attached drawings of the specification Figure 1-8 As shown, further, an extrusion component 9 provided on the hook 5 is further included. 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.

[0026] In order to position the enameled wire 3 during the winding process; since the enameled wire 3 enters the hook 5 at an inclined angle, the enameled wire 3 presses on the extrusion component 9, the extrusion component 9 moves and pulls the limiting component 8 to move, and the limiting component 8 extends forward from the side wall of the hook 5 until the limiting component 8 just abuts above the enameled wire 3, so that the limiting component 8 positions the enameled wire 3; the pressure generated during the winding of the enameled wire 3 pushes the limiting component 8 to move and position the enameled wire 3; when it is necessary to disassemble the limiting component 8, the limiting component 8 is released through the release component 7. Subsequently, the limiting component 8 resets. After the limiting component 8 resets, the enameled wire 3 moves out from one side of the limiting component 8. Also, because the enameled wire 3 enters the hook 5 at an inclined angle, the reset process of the limiting component 8 does not interfere with the enameled wire 3; it is convenient to position and remove the enameled wire 3, making the winding and disassembly processes of the enameled wire 3 more convenient.

[0027] In one embodiment, please refer to the attached drawings of the specificationFigure 1 and 3 As shown in FIGS. 8, the limiting component 8 includes a support 82 provided on the hook 5, a limiting rod 81 provided on the support 82, a sliding rod 83 provided on the support 82. Both the limiting rod 81 and the sliding rod 83 slide on the support 82. The sliding rod 83 is rotatably connected to the limiting rod 81, and the sliding rod 83 and the limiting rod 81 are connected by a pin 84. A plurality of slots 87 are provided on the sliding rod 83, and the slots 87 are inserted into the release component 7. A second elastic member 85 is provided inside the support 82, and the second elastic member 85 is used to push the sliding rod 83 to reset. A pulling wire 86 is provided on the sliding rod 83, and the end of the pulling wire 86 is connected to the pressing component 9 and moves with the pressing component 9. A wire hole is provided inside the support 82, and the wire hole is used to guide the movement of the pulling wire 86.

[0028] A release component 7 is provided on the support 82. When the release component 7 slides and the end of the limiting rod 81 is exposed, the limiting rod 81 rotates around the pin 84, and the enameled wire 3 disengages from below the limiting rod 81. When the enameled wire 3 presses on the pressing component 9, the pressing component 9 drives the pulling wire 86 to move, driving the sliding rod 83 and the limiting rod 81 to extend outward from the inside of the support 82 and be located above the enameled wire 3.

[0029] When it is necessary to limit the limiting component 8, when the pressing component 9 is pressed by the enameled wire 3, the pressing component 9 pulls the pulling wire 86, and the pulling wire 86 slides inside the wire hole. Due to the existence of the wire hole, the pulling wire 86 during the movement can be in a taut state, and the pulling wire 86 is always guided by the wire hole during movement. The pulling wire 86 can pull the sliding rod 83 to move, and the movement of the sliding rod 83 drives the movement of the limiting rod 81. Until the pressing component 9 moves to the maximum position, the pin 84 moves out of the inside of the support 82 along with the limiting rod 81 and is located below the release component 7, and the limiting rod 81 just moves above the enameled wire 3. Refer to the attached drawings of the specification Figure 6 As shown, the ends of the limiting rod 81 and the sliding rod 83 are in contact with each other, and the limiting rod 81 is limited and cannot be turned downward, realizing the positioning of the enameled wire 3. When it is necessary to remove the enameled wire 3, the release component 7 is moved so that the pin 84 moves out from below the release component 7, releasing the limiting rod 81. When the enameled wire 3 moves upward, the enameled wire 3 will push the limiting rod 81 to rotate around the pin 84. The enameled wire 3 is no longer restricted by the limiting rod 81, and the enameled wire 3 moves out of the inside of the hook 5, making the disassembly process more convenient when disassembling the enameled wire 3.

[0030] In one embodiment, please continue to refer to the attached drawings of the specification Figure 3-8As shown, the extrusion assembly 9 includes an extrusion block 91 disposed 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 drawing 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 disposed inside the hook 5 for pushing the extrusion block 91 to reset; a guide rod 93 is disposed on the extrusion block 91 and slides inside the hook 5.

[0031] In order that when the enameled wire 3 contacts the extrusion block 91, the extrusion block 91 drives the opening groove 92 to move. During the movement of the opening groove 92, sufficient clearance space is provided for the wire drawing 86, so that the wire drawing 86 will not be damaged by extrusion during movement; the provided guide rod 93 guides the movement of the extrusion block 91, facilitating the extrusion block 91 to move along the direction of the guide 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 drawing 86 to pull the sliding rod 83 and the limiting rod 81 to move until the limiting rod 81 positions the enameled wire 3.

[0032] In one embodiment, please continue to refer to the attached drawings of the specification Figure 3-8 As shown, the release assembly 7 includes a stop rod 71 disposed on the support 82. The stop rod 71 slides on the support 82. A pull rod 72 is disposed on the stop rod 71. A plug rod 73 is disposed on the pull rod 72. The plug rod 73 is inserted into the jack; a tension spring is disposed inside the hook 5 for pulling the pull rod 72.

[0033] To provide a more convenient operation when disassembling the enameled wire 3, pull the pulling rod 72. The pulling rod 72 is separated from the blocking rod 71. The blocking rod 71 can slide on the support 82. When the blocking rod 71 contracts from the rotating pin 84, the blocking 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, so as to achieve the effect of quick disassembly. Further, through the insertion of the insertion rod 73 and the insertion hole, the moved sliding rod 83 will not move due to the acting force of the second elastic member 85, and thus the positions of the sliding rod 83 and the limiting rod 81 can be stabilized; after pulling the pulling rod 72, the blocking rod 71 moves and the limiting rod 81 is not limited. At this time, the enameled wire 3 presses on the extrusion block 91. The extrusion block 91 pulls the pull wire 86, and the pull wire 86 pulls the sliding rod 83. The sliding rod 83 will not move backward due to the acting force 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 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 into the interior of the support 82, which is convenient for the limiting rod 81 to slide out of the interior 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 process of winding the enameled wire 3.

[0034] In another embodiment, please continue to refer to the attached drawings of the specification Figure 1 and 9 -11 as shown, the engaging assembly 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 in the wire groove 11. The first elastic member 64 is used to push the clamping block 63 to move into the interior of the clamping hole.

[0035] The existing groove wedge 62 is generally of 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 the enameled wire 3 losing paint. The enameled wire 3 after maintenance will not be able to be used continuously.

[0036] During installation, first place the slot wedge 62 inside the wire 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 wire slot 11 above the slot wedge 62. Press firmly on the slot wedge 62 during the installation process. After the clamping block 63 is inserted into the wire 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 wire slot 11. When disassembling the slot wedge 62, simply pull the clamping plate 61 to separate it from the slot wedge 62, and the clamping block 63 will disengage from the inside of the clamping hole.

[0037] 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. 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 pivot 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 wire 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 wire slot 11 above the slot wedge 62. Press firmly on the slot wedge 62 during the installation process. After the clamping plate 61 is inserted into the wire 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 wire slot 11. When the enameled wire 3 needs to be removed, pull the pull rod 72, and the pull rod 72 is separated from the stop rod 71. The stop rod 71 can slide on the support 82. When the stop rod 71 retracts from the pivot 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 pivot pin 84. 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 sliding rod 83 to move, driving the limiting rod 81 to be received inside the support 82.
