Embodiment 1

[0060] In a typical embodiment of the present invention, refer to figure 1 and figure 2 As shown, a protection device for replacing the oil deflector ring, including a first protection part, the first protection part can be connected with the gear box, and can limit the gear box bearing, so as to stabilize the gear box and avoid the gear box bearing Collision occurs; and the first protective component is provided with a size measuring groove capable of measuring the oil slinger mounting seat of the gearbox.

[0061] Further, the first protection 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 tapered roller bearing of the gearbox, and the first protection component It can be detachably connected with the gearbox case. When in use, the outer section 2 is connected with the gearbox case to prevent foreign ob...

Embodiment 2

[0071] In a typical implementation of the present invention, a protection device for replacing an oil slinger, on the basis of the first protection component in Embodiment 1, this embodiment also provides a second protection component, the second protection The component is used to be fixed with the first protection component, and is used to cover the size measuring groove of the first protection component, so as to prevent the magnetic particle flaw detection fluid from entering the inside of the gear box.

[0072] Further, refer to Figure 5 , Figure 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 inside of the base body 8 is bent toward the inner end surface of the base body to form a groove, the groove is used for installing a sealing ring 9 (such as an O-ring), and the sealing ring 9 protrudes from the The groove is set so that when the second protection part is matched with the firs...

Embodiment 3

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

[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 for setting the first protective component and the second protective component, so that the first protective component and the second Storage of protective parts.

[0082] Furthermore, the disassembly platform also places a heater, which can be installed on the gear shaft, and the heater is used to heat back the oil slinger of the gearbox; specifically, the heater can be an electromagnetic induction heater, and of course the heater can also be of other types heater.

Abstract

The invention discloses a protection device for replacing an oil retainer, a dismounting and mounting platform and an oil retainer replacing method. The problems that in the prior art, a gear box oil retainer is large in replacement difficulty and low in operation efficiency are solved, and the device has the beneficial effects that the operation efficiency can be improved, and the overhaul quality can be improved. According to the specific scheme, the protection device for replacing the oil retainer comprises a first protection part, and the first protection part can be connected with a gear box and can limit a gear box bearing so as to stabilize the gear box and prevent the gear box bearing from being collided; and the first protection part is provided with a size measuring groove capable of measuring a gear box oil retainer mounting seat.

Description

technical field [0001] The invention relates to the field of rail transportation, in particular to a protection device for replacing an oil deflector ring, a disassembly platform and a method for replacing the oil deflector ring. 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 return to the factory for advanced repairs after the set time of operation. During the advanced repair process of rail transit vehicles such as EMUs, the oil deflector ring needs to be updated due to excessive wear of the oil deflector ring or structural modification of the oil deflector ring. When the oil deflector ring needs to be replaced, the bearing cap on the corresponding side needs to be removed. Since the gearbox uses tapered roller bearings, after the bearing cap is removed, the gearbox will move, and moving the gearbox will ea...
