Embodiment 1

[0060] In an exemplary embodiment of the present invention, reference is made to figure 1 and figure 2 As shown, a protective device for replacing an oil deflector includes a first protective component, the first protective component can be connected with the gearbox and can limit the bearing of the gearbox, so as to stabilize the gearbox and avoid the bearing of the gearbox A bump occurs; and the first protective component is provided with a dimension measuring groove capable of measuring the mounting seat of the oil deflector of the gearbox.

[0061] Further, the first protective component includes an outer section 2 and an inner section 3, the inner section 3 is arranged inside the outer section 2 and is fixedly connected with the outer section 2, the inner section is used to cooperate with the gear box tapered roller bearing, and the first protective component It can be detachably connected to the gearbox case. When in use, the outer section 2 is connected to the gearbox...

Embodiment 2

[0071] In a typical embodiment of the present invention, a protective device for replacing an oil slinger, on the basis of the first protective component in the first embodiment, this embodiment also provides a second protective component. The component is used to be fixed with the first protective component, and is used to cover the dimension measuring groove of the first protective component, so as to prevent the magnetic particle flaw detection liquid from entering the inside of the gear box.

[0072] Further, refer to Figure 5 , Image 6 and Figure 7 As shown, the second protective component includes a base body 8, the base body 8 is an annular structural member, the inner side of the base body 8 is bent toward the inner end surface of the base body to form a groove, and the groove is used to install a sealing ring 9 (such as an O-ring), and the sealing ring 9 protrudes from The groove is arranged so that when the second protective part is matched with the first protec...

Embodiment 3

[0080] In a typical embodiment of the present invention, a disassembly and assembly platform includes a platform body, and the first protective component described in Embodiment 1 and the second protective component described in Embodiment 2 are placed on the platform body.

[0081] It is easy to understand that the platform body can be provided with a first card slot and a second card slot, and the first card slot and the second card slot are respectively used to set the first protection part and the second protection part, so that the first protection part and the second Storage of protective parts.

[0082] Further, a heater is also placed on the disassembly and assembly platform, and the heater can be installed on the gear shaft, and the heater is used to thermally remove the oil baffle ring of the gear box; heater.

Abstract

The invention discloses a protection device, a disassembly platform and a method for replacing the oil deflecting ring, which solves the problems of high difficulty in replacing the oil deflecting ring of a gear box and low operating efficiency in the prior art, and has the advantages of improving operation efficiency. Efficiency, the beneficial effect of improving the quality of maintenance, the specific scheme is as follows: a protection device for replacing the oil deflector ring, including a first protection part, the first protection part can be connected with the gearbox, and can limit the bearing of the gearbox position, to stabilize the gearbox and prevent the gearbox bearing from colliding; and the first protective part is provided with a size measuring groove capable of measuring the oil deflector ring mounting seat of the gearbox.

Description

technical field [0001] The invention relates to the field of rail transportation, in particular to a protective device for replacing an oil slinger, a disassembly and assembly platform and a method for replacing the oil slinger. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] Rail transit vehicles need to be returned to the factory for advanced repair after running for a set time. In the process of advanced repair of rail transit vehicles such as EMUs, the oil baffles need to be updated due to excessive wear of the oil baffle ring or structural transformation of the oil baffle ring. When the oil deflector needs to be replaced, the bearing cover on the corresponding side needs to be removed. Since the gear box adopts tapered roller bearings, after the bearing cover is removed, the gear box will move, and moving the gear box will easily caus...
