Description

Technical Field

[0001] This application relates to the field of bogie coupling design technology, and particularly to a coupling turntable and a bogie. Background Technology

[0002] As is well known, couplings are widely used in rail vehicles. Gear couplings are commonly used in rail vehicles. The two half couplings on the motor side and the gearbox side are connected by bolts to transmit torque. To ensure structural strength, there are usually high requirements for the number of bolts and other fasteners and the preload.

[0003] In existing technologies, when a fault such as a stuck motor bearing occurs, the bogie of the train must be lifted, and a small roller cart must be used to lower the wheel corresponding to the faulty motor onto the cart before the vehicle can be towed back to the depot. This is extremely inconvenient for rescue operations, and the permissible speed for towing the train during rescue is very low. For trains driven by permanent magnet synchronous motors, under towing conditions, the motor is driven by the wheels, turning the motor into a generator. The generated current cannot be consumed in time, causing some components in the traction circuit to overheat, which necessitates limiting the train's rescue speed. In both of these situations, even if the fasteners of the two half-couplings are removed, the flanges of the two half-couplings will still contact each other because the internal gear rings of the two half-couplings are supported on the drum-shaped teeth. When the pinion shaft of the gearbox rotates, the flanges will rub against each other, which is unacceptable for vehicle operation. Therefore, even if the left and right half-couplings of this type of coupling are decoupled, it is still impossible to tow the vehicle directly or drive it back to the depot.

[0004] Therefore, how to avoid the difficulty of decoupling the two half-couplings and the incomplete decoupling is a problem that needs to be solved by those skilled in the art. Summary of the Invention

[0005] The purpose of this application is to provide a coupling rotary table that improves the ease of decoupling and enables complete decoupling. Another purpose of this application is to provide a bogie including the aforementioned coupling rotary table.

[0006] To achieve the above objectives, this application provides a coupling rotary table for connecting a motor-side half-coupling and a gearbox-side half-coupling, comprising:

[0007] A splined rotary component has a cylindrical structure and a first circular plate extending along a plane perpendicular to its axis. The outer circumferential surface of the first cylindrical part of the splined rotary component is provided with splines.

[0008] The toothed rotating component has a cylindrical structure and a second circular plate extending along a plane perpendicular to its axis. The second cylindrical part of the toothed rotating component is rotatably fitted inside the first cylindrical part of the splined rotating component. The second circular plate of the toothed rotating component has end face teeth on the side near the first cylindrical part.

[0009] The adjusting slip ring is detachably disposed on the outer circumferential surface of the second cylindrical part of the toothed rotating part and can slide along the spline. Both the splined rotating part and the toothed rotating part can be connected to the adjusting slip ring. The adjusting slip ring is provided with a toothed groove that mates with the end face teeth on the side near the toothed rotating part.

[0010] Preferably, the adjusting slip rings are arranged in a cross-shaped symmetrical arrangement on the outer circumferential surface of the second cylindrical part of the toothed rotating component.

[0011] Preferably, the adjusting slip ring is provided with an overload protection groove on the side near the toothed rotating part to prevent the transmitted torque from being overloaded.

[0012] Preferably, the splined rotating component and the toothed rotating component are rotatably connected by bearings.

[0013] Preferably, two bearings are provided between the splined rotating component and the toothed rotating component, and a spacer is installed between the two bearings.

[0014] Preferably, the holes inside both the splined rotating component and the toothed rotating component are stepped holes. The end of the inner circumferential surface of the first cylindrical portion of the splined rotating component has a first groove for installing a retaining ring for the outer ring hole. The end of the outer circumferential surface of the second cylindrical portion of the toothed rotating component has a second groove for installing a retaining ring for the inner ring shaft. The bearing near the splined rotating component is engaged with the stepped surface of the splined rotating component by a retaining ring for the inner ring shaft installed in the second groove. The bearing near the toothed rotating component is engaged with the stepped surface of the toothed rotating component by a retaining ring for the outer ring hole installed in the first groove.

[0015] Preferably, the first circular plate surface of the splined rotating component is chamfered at the connection between it and the first cylindrical portion, and the second circular plate surface of the toothed rotating component is chamfered at the connection between it and the second cylindrical portion.

[0016] Preferably, both the splined rotary component and the toothed rotary component are connected to the motor-side half-coupling and the gearbox-side half-coupling respectively by bolts.

[0017] Preferably, the adjusting slip ring is connected to a splined or toothed rotating part by bolts.

[0018] This application also provides a bogie including the coupling slewing table described above.

[0019] Compared to the aforementioned background technology, this application provides a coupling rotary table for connecting a motor-side half-coupling and a gearbox-side half-coupling, comprising: a splined rotary component, a toothed rotary component, and an adjusting slip ring; the splined rotary component has a cylindrical structure and a first circular plate extending along a plane perpendicular to its axis, and the outer circumferential surface of the first cylindrical portion of the splined rotary component is provided with splines; the toothed rotary component has a cylindrical structure and a second circular plate extending along a plane perpendicular to its axis, the second cylindrical portion of the toothed rotary component is rotatably fitted inside the first cylindrical portion of the splined rotary component, and the side of the second circular plate of the toothed rotary component near the first cylindrical portion is provided with end face teeth; the adjusting slip ring is detachably disposed on the outer circumferential surface of the second cylindrical portion of the toothed rotary component and can slide along the spline, both the splined rotary component and the toothed rotary component can be connected to the adjusting slip ring, and the side of the adjusting slip ring near the toothed rotary component is provided with a tooth groove that mates with the end face teeth.

[0020] Specifically, the splined rotary component is fixedly connected to the motor-side half-coupling, and the toothed rotary component is fixedly connected to the gearbox-side half-coupling. When the adjusting slip ring slides to the side close to the splined rotary component and is fixedly connected to it, the splined rotary component and the toothed rotary component can rotate freely and are connected to each other. When the adjusting slip ring slides to the side closest to the toothed rotating component and is fixedly connected to it, the end face teeth on the toothed rotating component will mesh with the toothed grooves on the adjusting slip ring. At this time, since the adjusting slip ring is connected to the splined rotating component via a spline, the adjusting slip ring will not be able to rotate relative to the splined rotating component. Therefore, the splined rotating component and the toothed rotating component will also not be able to rotate relative to each other. In this way, the torque transmitted from the motor side is transmitted to the adjusting slip ring through the splined rotating component, then to the toothed rotating component through the adjusting slip ring, and finally to the half-coupling on the gearbox side. When it is necessary to decouple, simply slide the adjusting slip ring to the side of the splined rotating component, and the torque transmitted from the motor side will no longer be able to be transmitted to the toothed rotating component through the adjusting slip ring, thus achieving complete decoupling.

[0021] In summary, the above setup can solve the problems of difficult and incomplete decoupling of the two half-couplings, and improve the convenience of decoupling. Attached Figure Description

[0037] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0038] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0039] It should be noted that the directional terms such as "upper end," "lower end," "left side," and "right side" mentioned below are defined based on the accompanying drawings in the instruction manual.

[0040] Please see Figures 1 to 5 This application provides a coupling rotary table 100 for connecting a motor-side half-coupling 200 and a gearbox-side half-coupling 300. It includes: a splined rotary component 110, a toothed rotary component 120, and an adjusting slip ring 130. The splined rotary component 110 has a cylindrical structure and a first circular plate surface 111 extending along a plane perpendicular to its axis. A spline 1121 is provided on the outer circumferential surface of the first cylindrical portion 112 of the splined rotary component 110. The toothed rotary component 120 has a cylindrical structure and a second circular plate surface 121 extending along a plane perpendicular to its axis. A spline 1121 is provided on the outer circumferential surface of the second cylindrical portion 112 of the toothed rotary component 120. 22 is rotatably sleeved inside the first cylindrical portion 112 of the splined rotating member 110. The second circular plate surface 121 of the toothed rotating member 120 is provided with end face teeth 1211 on the side near the first cylindrical portion 112. The adjusting slip ring 130 is detachably provided on the outer circumferential surface of the second cylindrical portion 122 of the toothed rotating member 120, and the adjusting slip ring 130 can slide along the spline 1121. Both the splined rotating member 110 and the toothed rotating member 120 can be connected to the adjusting slip ring 130. The adjusting slip ring 130 is provided with a tooth groove 132 that mates with the end face teeth 1211 on the side near the toothed rotating member 120.

[0041] Specifically, the coupling rotary table 100 is used to connect the motor-side half coupling 200 and the gearbox-side half coupling 300. The splined rotary component 110 is fixedly connected to the motor-side half coupling 200, and the toothed rotary component 120 is fixedly connected to the gearbox-side half coupling 300. The splined rotary component 110 and the toothed rotary component 120 are rotatably connected. By adjusting the left and right movement of the slip ring 130, the splined rotary component 110 and the toothed rotary component 120 can rotate freely or be fixed, so that they can rotate relative to each other or be constrained.

[0042] In other words, when the adjusting slip ring 130 slides to the side close to the splined rotating member 110 and is fixedly connected to the splined rotating member 110, the splined rotating member 110 and the toothed rotating member 120 can rotate freely and are connected to each other; when the adjusting slip ring 130 slides to the side close to the toothed rotating member 120 and is fixedly connected to the splined rotating member 110, the end face teeth 1211 provided on the toothed rotating member 120 will mesh with the tooth grooves 132 provided on the adjusting slip ring 130. The adjusting slip ring 130 is connected to the splined rotating member 110 through the spline 1121 to realize the transmission of torque. At this time, the adjusting slip ring 130 cannot rotate relative to the splined rotating member 110. Therefore, the splined rotating member 110 and the toothed rotating member 120 will also not be able to rotate relative to each other. As can be seen, under normal operating conditions, the adjusting slip ring 130 is fixed on the outer circumferential surface of the second cylindrical part 122 of the toothed rotating part 120, while under special operating conditions, the adjusting slip ring 130 is fixed on the outer circumferential surface of the first cylindrical part 112 of the splined rotating part 110.

[0043] In this embodiment, in order to enable the adjusting slip ring 130 to transmit torque more stably and prevent it from being damaged by excessive torque, the number of end face teeth 1211 provided on the toothed rotating part 120 can be determined according to actual needs. At the same time, the number of tooth grooves 132 provided on the adjusting slip ring 130 is the same as the number of end face teeth 1211.

[0044] In this way, the torque transmitted from the motor side is transmitted to the adjusting slip ring 130 through the splined rotating component 110, then to the toothed rotating component 120 through the adjusting slip ring 130, and finally to the gearbox-side half coupling 300. When it is necessary to decouple, simply slide the adjusting slip ring 130 to one side of the splined rotating component 110, and the torque transmitted from the motor side will no longer be able to be transmitted to the toothed rotating component 120 through the adjusting slip ring 130, thus achieving complete decoupling.

[0045] In summary, the above setup can solve the problems of difficult and incomplete decoupling of the two half-couplings, and improve the convenience of decoupling.

[0046] Preferably, the adjusting slip ring 130 is arranged in a cross-shaped symmetrical arrangement on the outer peripheral surface of the first cylindrical portion 112 of the splined rotating part 110.

[0047] Understandably, the adjusting slip ring 130 is mounted on the splined rotating component 110. When in the decoupled state, the splined rotating component 110 can rotate relative to the toothed rotating component 120, and the adjusting slip ring 130 and the splined rotating component 110 are in the same state.

[0048] Please see Figure 4 In this embodiment, the adjusting slip ring 130 is preferably arranged in a cross-shaped symmetrical manner on the outer peripheral surface of the first cylindrical portion 112 of the splined rotating part 110. Specifically, the adjusting slip ring 130 is arranged in a cross-shaped structure on the splined rotating part 110. This arrangement can reduce the weight of the adjusting slip ring 130 and reduce the number of bolts that need to be disassembled and tightened when the adjusting slip ring 130 switches between the left and right states. In addition, this arrangement can also reduce manufacturing costs.

[0049] Preferably, the adjusting slip ring 130 is provided with an overload protection groove 131 on the side near the toothed rotating part 120 to prevent the transmitted torque from being overloaded and to protect the main components, the splined rotating part 110 and the toothed rotating part 120, from damage.

[0050] Understandably, when the coupling rotary table 100 needs to transmit torque, the adjusting slip ring 130 will move to the right side to closely adhere to the toothed rotary component 120 and be fixedly connected to it. The torque will be transmitted to the adjusting slip ring 130 through the spline 1121 on the splined rotary component 110. Since the adjusting slip ring 130 is fixedly connected to the toothed rotary component 120, the torque will finally be transmitted to the toothed rotary component 120 through the adjusting slip ring 130. As a result, when the rotational resistance on one side of the toothed rotary component 120 is too high, it is easy to cause significant damage to the motor on the left side. Therefore, the overload protection groove 131 is provided.

[0051] Please see Figure 5 In this embodiment, an overload protection groove 131 is provided on the side of the adjusting slip ring 130 near the toothed rotating component 120. This overload protection groove 131 has the characteristics of high precision and good fatigue resistance. In this way, when the motor is overloaded, the adjusting slip ring 130 will break at the position of the overload protection groove 131, disconnecting the adjusting slip ring 130 from the toothed rotating component 120, causing the splined rotating component 110 to rotate relative to the toothed rotating component 120, thus protecting the motor from damage. Of course, the actual size of the overload protection groove 131 needs to be set according to the maximum torque that the motor and the adjusting slip ring 130 can withstand.

[0052] Preferably, the splined rotating part 110 and the toothed rotating part 120 are rotatably connected by a bearing 140.

[0053] Understandably, when the adjusting slip ring 130 moves to the left, that is, when it is connected to the splined rotary component 110, the splined rotary component 110 and the toothed rotary component 120 are in a decoupled state, and the splined rotary component 110 and the toothed rotary component 120 can rotate relative to each other. Therefore, the splined rotary component 110 and the toothed rotary component 120 can be connected by rotary parts.

[0054] In this embodiment, the connection is preferably made via a bearing 140. The bearing 140 has low frictional resistance, high mechanical efficiency, compact structure, and light weight. In addition, the bearing 140 is standardized in size, interchangeable, easy to install and disassemble, and convenient to maintain.

[0055] Of course, other rotating parts can be selected according to the actual situation, as long as they can achieve the rotational connection between the splined rotating part 110 and the toothed rotating part 120.

[0056] Preferably, two bearings 140 are provided between the splined rotating part 110 and the toothed rotating part 120, and a spacer 150 is installed between the two bearings 140.

[0057] Specifically, in this embodiment of the application, two bearings 140 are arranged side by side, and a spacer 150 is installed between the two bearings 140.

[0058] The purpose of setting two bearings 140 between the splined rotating component 110 and the toothed rotating component 120 is to resist bending moment, while increasing the load-bearing capacity and stability of the coupling rotary table 100, thereby improving its overall performance. In this application, the purpose of installing a spacer 150 between the two bearings 140 is firstly to fix the outer rings of the two bearings 140; secondly, to separate the two bearings 140, ensuring a reasonable clearance between them so that they can work without interfering with each other; and finally, to store grease, reducing friction during bearing rotation and extending their service life.

[0059] Preferably, the holes inside the spacer 150 installed between the two bearings 140 are all stepped holes. The end of the inner circumferential surface of the first cylindrical part 112 of the splined rotating part 110 is provided with a first groove 1122 for installing the outer ring hole retainer 160. The end of the outer circumferential surface of the second cylindrical part 122 of the toothed rotating part 120 is provided with a second groove 1221 for installing the inner ring shaft retainer 170. The side of the bearing 140 near the splined rotating part 110 is engaged with the stepped surface of the splined rotating part 110 by the inner ring shaft retainer 170 installed in the second groove 1221. The side of the bearing 140 near the toothed rotating part 120 is engaged with the stepped surface of the toothed rotating part 120 by the outer ring hole retainer 160 installed in the first groove 1122.

[0060] Specifically, the holes inside both the splined rotary component 110 and the toothed rotary component 120 are stepped holes, such as... Figure 2 and Figure 3 As shown, in the hole of the splined rotating component 110, a step is provided on the left side for engaging the left bearing 140, and in the hole of the toothed rotating component 120, a step is provided on the right side for engaging the right bearing 140; in addition, a second groove 1221 is provided on the toothed rotating component 120 corresponding to the position of the step of the splined rotating component 110, and a first groove 1122 is provided on the splined rotating component 110 corresponding to the position of the step of the toothed rotating component 120.

[0061] In this configuration, the outer ring of the left bearing 140 is fixed by the stepped surface of the splined rotating member 110, and the inner ring of the bearing 140 is fixed by the retaining ring 170 installed in the second groove 1221. The inner ring of the right bearing 140 is fixed by the stepped surface of the toothed rotating member 120, and the outer ring of the bearing 140 is fixed by the retaining ring 160 installed in the outer ring hole of the first groove 1122. Bearings 140 are separated and fixed from each other by spacers 150. This configuration facilitates the disassembly, installation, and maintenance of the coupling rotary table 100.

[0062] Preferably, the first circular plate surface 111 of the splined rotary component 110 is chamfered at the connection between the first circular plate surface 111 and the first cylindrical portion 112, and the second circular plate surface 121 of the toothed rotary component 120 is chamfered at the connection between the second circular plate surface 121 and the second cylindrical portion 122.

[0063] To prevent scratches to installers during the installation of the coupling rotary table 100, chamfers are provided at sharp locations. The first circular plate surface 111 of the splined rotary component 110 is perpendicularly connected to the first cylindrical portion 112, and the second circular plate surface 121 of the toothed rotary component 120 is perpendicularly connected to the second cylindrical portion 122. Therefore, chamfers are provided at these connections. This design not only improves safety but also avoids stress concentration between the splined rotary component 110 and the toothed rotary component 120.

[0064] Preferably, the splined rotary component 110 and the toothed rotary component 120 are both connected to the motor-side half coupling 200 and the gearbox-side half coupling 300 respectively by bolts.

[0065] In this embodiment, 12 bolt holes are evenly arranged in a circular sequence on the first circular plate surface 111 of the splined rotary component 110 and the second circular plate surface 121 of the toothed rotary component 120, for mounting bolts to connect the motor-side half coupling 200 and the gearbox-side half coupling 300.

[0066] Preferably, the adjusting slip ring 130 is connected to the splined rotating part 110 or the toothed rotating part 120 by bolts.

[0067] Understandably, the adjusting slip ring 130 needs to be connected to the splined rotating part 110 when decoupling, and to the toothed rotating part 120 when coupling. In this embodiment, it is connected by bolts for easy disassembly, maintenance and installation.

[0068] In addition, this application also provides a bogie, including the coupling turntable 100 described above.

[0069] In summary, when using the aforementioned coupling rotary table 100, in the coupled state when torque transmission is required, the adjusting slip ring 130 is moved to the right and connected to the toothed rotary component 120. In the decoupled state when torque transmission is not required, the adjusting slip ring 130 is moved to the left and connected to the splined rotary component 110. This makes decoupling the two half-couplings simpler and more convenient, and also ensures that the decoupling of the two half-couplings is complete.

[0070] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0071] This document uses specific examples to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are only for the purpose of helping to understand the solution and core ideas of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made to this application without departing from the principles of this application, and these improvements and modifications also fall within the protection scope of the claims of this application.
