Description

Technical Field

[0001] This utility model relates to the field of gearbox installation technology for new energy locomotives, and in particular to a vibration damping mounting base and a motor gearbox. Background Technology

[0002] In new energy locomotives, the motor gearbox is an assembly formed by combining the traction motor and the intermediate gearbox. The entire motor gearbox needs to be mounted onto the locomotive frame via the intermediate gearbox. During locomotive operation, the motor gearbox will rotate at high speed, and its stability directly affects the quality of the locomotive's overall power system.

[0003] In the existing technology, the intermediate gearbox is directly bolted to the locomotive frame, and the connection between the intermediate gearbox and the frame is a rigid connection. This will lead to the following technical problems or adverse effects:

[0004] 1. During locomotive operation, the vibration of the wheels is directly transmitted to the motor gearbox through the frame, which will have an adverse effect on the gear transmission inside the motor gearbox.

[0005] 2. The motor gearbox itself will also generate a certain amount of vibration during operation, and the existing rigid connection cannot play a buffering role.

[0006] 3. The frame is made of structural steel, and slight deformation is inevitable. The frame and motor gearbox are rigidly connected. When the frame is slightly deformed, it will cause compressive internal stress in the gearbox and the frame. Utility Model Content

[0036] The present invention will be further described in detail below through specific embodiments:

[0037] Example

[0038] See Figures 1-4 This embodiment provides a motor gearbox, including a traction motor 1, an intermediate gearbox 2, and a vibration damping mounting base 3 for connecting the vehicle frame and the motor gearbox.

[0039] The traction motor 1 is mounted on the intermediate gearbox 2 and is connected to the intermediate gearbox 2 for transmission. In this embodiment, the two traction motors 1 are arranged symmetrically with respect to the axis of the intermediate gearbox 2.

[0040] The intermediate gearbox 2 has connecting parts 21 for mounting vibration damping mounting bases 3. In this embodiment, the two connecting parts 21 are symmetrically arranged with respect to the axis of the intermediate gearbox 2, which facilitates the symmetrical mounting of two vibration damping mounting bases 3 on the intermediate gearbox 2.

[0041] The vibration damping mounting base 3 includes a base 31 and a buffer component.

[0042] The base 31 is used to connect the vehicle frame and the connecting component 21 to mount the motor gearbox into the vehicle frame. The base 31 is detachably connected to the vehicle frame. The base 31 is also detachably connected to the connecting component 21.

[0043] In a specific implementation scenario, the base 31 is plate-shaped; more specifically, the base 31 is a rectangular steel plate with a certain thickness.

[0044] Several buffer components are disposed between the connecting component 21 and the base 31. The number and unloading direction of the buffer components are unlimited, so as to buffer the motor gearbox in one or more directions, filter out the vibration and impact transmitted from the wheels to the frame, and buffer the vibration generated by the motor gearbox itself during operation, so as to protect the motor gearbox.

[0045] When in use, the base 31 of the vibration damping mounting seat 3 is installed on the connecting part 21 of the intermediate gearbox 2, and the buffer is positioned between the connecting part 21 and the base 31. Then the motor gearbox can be installed into the locomotive frame as a whole. The vibration damping mounting seat 3 has the advantages of convenient installation and strong operability.

[0046] In this embodiment, the base 31 is detachably connected to the vehicle frame by a first bolt, and the base 31 is detachably connected to the connecting component 21 by a second bolt 33. Specifically:

[0047] The connecting component 21 has a hole for threaded connection with the first bolt, and the base 31 has a plurality of mounting holes 311 through which the first bolt can pass. Preferably, the mounting holes 311 are through holes. One end of the first bolt passes through the mounting hole 311 and is threadedly connected to the frame.

[0048] The base 31 has several screw holes 312 that match the second bolt 33. The second bolt 33 is equipped with a flat washer 34 and an elastic washer 35. The flat washer 34 is located between the elastic washer 35 and the buffer element. The flat washer 34 and the elastic washer 35 provide anti-slip and anti-loosening protection for the second bolt 33. The first bolt can be configured in the same manner as the second bolt 33.

[0049] In this embodiment, the buffer includes a vibration damping pad 32 made of rubber, which can be clamped by the base 31 and the connecting component 21. In order to better fix the vibration damping pad 32, a plurality of through holes 321 matching the second bolt 33 are distributed on the vibration damping pad 32, and the second bolt 33 is disposed through the vibration damping pad 32.

[0050] Furthermore, the vibration damping mounting base 3 also includes a top cover 36, which is disposed between the buffer member and the connecting member 21. A first bolt and a second bolt 33 pass through the top cover 36. The top cover 36 provides better support for the connecting member 21 provided by the vibration damping mounting base 3.

[0051] In summary, this embodiment has at least the following beneficial effects:

[0052] 1. The buffer component provides a buffering effect on the motor gearbox in one or more directions, filtering out the vibration and impact of the vehicle body and buffering the vibration generated by the motor gearbox itself during operation, thereby protecting the motor gearbox.

[0053] II. The vibration damping mounting base 3 has the advantages of convenient installation and strong operability.

[0054] Third, two vibration damping mounting bases and two traction motors are symmetrically installed on the intermediate gearbox, which provides good stability.

[0055] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. For those skilled in the art, this utility model can have various modifications and variations. Without conflict, the embodiments and features described in this application can be arbitrarily combined with each other.
