Description

Technical Field

[0001] The present application relates to the technical field of bearing assembly, and particularly to an installation structure for a to-be-installed part. Background Art

[0002] A electric locomotive, also known as an electric train, refers to a train that obtains electrical energy from a power supply network (catenary) or a power supply rail and then drives the vehicle to run through an electric motor. The electric locomotive mainly includes a traction motor, axle box bearings, wheels, axles, and a driving gear box. The traction motor, as a power source, has its output end connected to the driving gear box, converting the rotational motion of the traction motor into a low-speed and high-torque output suitable for driving the wheels. The driving gear box meshes with the axle, and the axle is used to connect the wheels and the car body. Both ends of the axle are axially connected through axle box bearings, thereby driving the wheels to rotate. The driving gear bearing is arranged inside the driving gear box and is used to support the driving gear.

[0003] When the electric locomotive actually runs for more than a certain number of kilometers, the driving gear bearing needs to be replaced. Since the driving gear bearing is blocked by the wheels during installation, the operator needs to disassemble the traction motor, axle box bearings, axles, and wheels in sequence, and then disassemble the bearings on the driving gear box in sequence. After replacing the bearings, the wheels are press-fitted, and a reverse pressure test is performed on the wheels after a certain time interval.

[0042] Unless otherwise specified, the term "plurality" means two or more.

[0043] As described in the background art, an electric locomotive, also known as an electric train, refers to a train that obtains electrical energy from a power supply network (catenary) or a power supply rail and then drives the vehicle to run through an electric motor. An electric locomotive mainly includes a traction motor, axle box bearings, wheels, axles, and a driving gearbox. The traction motor, as a power source, has its output end connected to the driving gearbox, converting the rotational motion of the traction motor into a low-speed and high-torque output suitable for driving the wheels. The driving gearbox meshes with the axle, and the axle is used to connect the wheels and the vehicle body. Both ends of the axle are axially connected through axle box bearings, thereby driving the wheels to rotate.

[0044] When the electric multiple unit has run more than a certain number of kilometers in actual operation, the bearings of the driving gear need to be replaced. The operator needs to disassemble the traction motor, axle box bearings, axles, and wheels in sequence, and then disassemble the bearings on the driving gearbox in sequence. After replacing the bearings, press-fit the wheels, and conduct a reverse pressure test on the wheels after a certain period of time. After the reverse pressure test passes, assemble the axle box bearings and the traction motor.

[0045] However, when replacing the bearings of the driving gear of an electric locomotive, the operation process is complex. If the axle box bearings and the axles and wheels are not disassembled, when installing the bearings inside the driving gearbox, due to the obstruction of the wheels, the operating space is small, which is not convenient for installation and the replacement efficiency is low.

[0046] To solve the above problems, the embodiment of the present application provides an installation structure for a to-be-installed part, which is used to install the to-be-installed part into a target device. An installation hole is provided on the target device, and a part of the to-be-installed part is disposed inside the installation hole. The installation structure of the to-be-installed part includes a moving part, which is used to be disposed on the to-be-installed side of the target device and is used to abut against the to-be-installed part. At least one first through hole is provided on the moving part; a fixing part, which is used to abut against the other side of the target device. A second through hole is provided on the fixing part; at least one rotating part is sequentially inserted through the second through hole and the first through hole to connect the moving part and the fixing part. The rotating part is configured to rotate to drive the moving part to move along the axial direction of the rotating part, so as to push the to-be-installed part into the installation hole; at least one first limiting part is disposed on the rotating part and abuts against the fixing part. The first limiting part is configured to limit the axial displacement of the rotating part.

[0047] By rotating the rotating part, the installation of the to-be-installed part can be realized, avoiding the problem that it is not convenient for the operator to operate due to limited operating space when manually pushing the to-be-installed part into the installation hole, and improving the installation efficiency.

[0048] When the target device is a driving gearbox and the part to be installed is a bearing, when replacing the bearing, by adopting the installation structure of the part to be installed provided by the embodiment of the present application, it can adapt to the narrow installation space between the wheel and the driving gearbox, so there is no need to disassemble the axle box bearing, the axle and the wheel, nor is it necessary to conduct a back pressure test on the wheel, which reduces the operation difficulty, shortens the replacement cycle, and greatly improves the replacement efficiency.

[0049] The technical solution of the embodiment of the present application and how the technical solution of the embodiment of the present application solves the above technical problems will be described in detail below with specific embodiments. The following several specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below with reference to the drawings.

[0050] Please refer to Figure 1 、 Figure 2 and Figure 3 。This embodiment provides an installation structure for a part to be installed, which is used to install the part to be installed 20 into the target device 10. An installation hole 11 is provided on the target device 10, and a part of the part to be installed 20 is arranged in the installation hole 11. The installation structure of the part to be installed includes a moving member 100, which is used to be arranged on the side to be installed of the target device 10 and is used to abut against the part to be installed 20. At least one first through hole 110 is provided on the moving member 100; a fixing member 200, which is used to abut against the other side of the target device 10. At least one second through hole 210 is provided on the fixing member 200; at least one rotating member 300 is sequentially inserted into the second through hole 210 and the first through hole 110. The rotating member 300 is configured to rotate to drive the moving member 100 to move along the axial direction of the rotating member 300, so as to push the part to be installed 20 into the installation hole 11; at least one first limiting member 400 is arranged on the rotating member 300 and abuts against the fixing member 200. The first limiting member is configured to limit the axial displacement of the rotating member.

[0051] Specifically, when replacing the bearings in the driving gearbox of an electric multiple unit, the bearings need to be replaced and installed. When installing the bearings, the operator has to reach into the space between the wheel and the driving gearbox to push the bearings into the driving gearbox. Due to the obstruction of the wheel, it is inconvenient for the operator to apply force during installation, and it is difficult to install the bearings in place at one time. When the bearings are not installed in place, a hammer needs to be used to hammer them so that the bearings are fully embedded in the mounting hole 11 on the driving gearbox. However, due to the obstruction of the wheel, the operator has no space for hammering. Therefore, the axle box bearings, axles, and wheels need to be disassembled before the bearings can be pushed into the driving gearbox. After disassembling the axle box bearings, axles, and wheels, in order to ensure the connection reliability between the wheel and the axle, as well as the integrity and safety of the wheel, a reverse pressure test needs to be carried out on the wheel 24 hours later, which greatly increases the cycle time for replacing the driving gear bearings and results in extremely low replacement and installation efficiency.

[0052] In this embodiment, the part to be installed 20 is a bearing, and the target device 10 is a driving gearbox. Hereinafter, the installation of the bearing into the driving gearbox by using the installation structure of the part to be installed provided in this embodiment will be described.

[0053] Among them, a mounting hole 11 is provided on the driving gearbox. The mounting hole 11 is a through hole that runs through the entire driving gearbox. A stepped groove matching the size of the bearing is formed in the mounting hole 11. The bearing needs to be pushed into the mounting hole 11 from the right side, i.e., the side blocked by the wheel, after being frozen, so as to achieve the installation of the bearing. When the bearing returns to room temperature, due to thermal expansion and contraction, the outer diameter of the bearing will be slightly larger than the inner diameter of the mounting hole 11, thus achieving interference installation.

[0054] During actual installation, the operator can insert the bearing into the gap between the driving gearbox and the wheel, so that part of the bearing is located in the mounting hole 11. Then, the moving part 100 and the fixing part 200 are respectively abutted against both sides of the bearing, and the rotating part 300 is sequentially passed through the second through hole 210 on the fixing part 200 and the first through hole 110 on the moving part 100.

[0055] Among them, in this embodiment, the moving part 100 is arranged on the side of the bearing close to the wheel. The operator can insert the moving part 100 into the gap between the bearing and the wheel, and then fix the moving part 100 by passing the rotating part 300 through the first through hole 110 on the moving part 100. The fixing part 200 can be abutted against the side of the driving gearbox facing away from the vehicle, or can be arranged in the mounting hole 11 and abutted against the step in the mounting hole 11. It can be adaptively selected according to actual needs, and this embodiment does not impose any restrictions on this.

[0056] Specifically, in this embodiment, both the moving member 100 and the fixed member 200 are circular pressing plates. Among them, the size of the moving member 100 is slightly smaller than the size of the bearing, so that it can enter the mounting hole 11 together with the bearing, making the bearing installed in place.

[0057] During actual installation, the rotating member 300 is passed through the second through hole 210 and the first through hole 110, and the first limiting member 400 on the rotating member 300 is abutted against the fixed member 200. By rotating the rotating member 300, the moving member 100 can be driven to move along the axial direction of the rotating member 300, so as to push the bearing into the mounting hole 11. There is no need for the operator to repeatedly hammer the bearing for installation, so it can adapt to a narrow working space. Furthermore, there is no need to disassemble the axle box bearing, the axle, and the wheel, nor is there a need for a backpressure test. Thus, the replacement cycle of replacing the bearing of the driving gearbox is greatly shortened, and the replacement efficiency is greatly improved.

[0058] Among them, in this embodiment, the rotating member 300 can be a screw, and the moving member 100 is meshed with the screw. At this time, since the first limiting member 400 abuts against the fixed member 200, the operator only needs to apply pressure to the first limiting member 400 and rotate the first limiting member 400, which can drive the screw to rotate. At this time, due to the setting of the first limiting member 400, the screw can only perform rotational motion and will not have axial displacement. Furthermore, the moving member 100 meshed with the screw can be driven to move along the axial direction of the screw to push the bearing into the mounting hole 11.

[0059] Specifically, to prevent the moving member 100 from rotating synchronously with the screw, the operator can hold the moving member 100 by hand to limit the rotation of the moving member 100.

[0060] Among them, the number of the rotating members 300 can be one or more. The number of the first through holes 110, the second through holes 210, and the first limiting members 400 is the same as the number of the rotating members, and they are arranged in one-to-one correspondence.

[0061] When the number of the rotating members 300 is one, the rotating member 300 can be concentrically installed with the moving member 100, or the moving member 100 can be eccentrically installed, so as to limit the moving member 100 from rotating synchronously with the rotating member 300. There is no need for the operator to hold it by hand, which greatly reduces the installation difficulty.

[0062] In another exemplary embodiment, the rotating member 300 can also be a lead screw, and balls matching the lead screw are arranged on the moving member 100. In the form of a ball screw, the rotational motion of the rotating member 300 is converted into the linear motion of the moving member 100.

[0063] Meanwhile, it should be noted that this embodiment does not limit the specific cooperation mode between the rotating member 300 and the moving member 100. Any cooperation mode that can convert the rotational motion of the rotating member 300 into the linear motion of the moving member 100 is within the scope covered by this embodiment. The operator can make an adaptive selection according to actual needs.

[0064] In an alternative embodiment, a first internal thread is provided in the first through hole 110, and an external thread is provided on the rotating member 300, and the first internal thread and the external thread are arranged to match each other.

[0065] Specifically, in this embodiment, a first internal thread is provided in the first through hole 110, and an external thread matching the first internal thread is provided on the rotating member 300. The rotating member 300 and the moving member 100 are engaged through the first through hole 110. Since the first limiting member 400 abuts against the fixing member 200, the operator only needs to apply pressure to the first limiting member 400 and rotate the first limiting member 400, which can drive the rotating member 300 to rotate. At this time, due to the setting of the first limiting member 400, the rotating member 300 can only perform rotational motion and will not undergo axial displacement, and thus can drive the moving member 100 engaged with the rotating member 300 to move along the axial direction of the rotating member 300 to push the bearing into the mounting hole 11.

[0066] In an alternative embodiment, the mounting structure of the to-be-mounted member further includes a second limiting member 500, and the second limiting member 500 is provided on the rotating member 300, and the second limiting member 500 abuts against the side of the moving member 100 away from the to-be-mounted member 20.

[0067] Specifically, in this embodiment, the mounting structure of the to-be-mounted member further includes a second limiting member 500 provided on the rotating member 300. The second limiting member 500 can abut against the side of the moving member 100 away from the to-be-mounted member 20, that is, away from the bearing. By providing the second limiting member 500, the position of the moving member 100 provided on the rotating member 300 can be restricted, preventing the moving member 100 from shifting or falling off, which may affect the effect of pushing the bearing.

[0068] In an alternative embodiment, a third through hole is formed in the second limiting member 500, the rotating member 300 is inserted into the third through hole, a second internal thread is provided in the third through hole, and an external thread is provided on the rotating member 300, and the second internal thread and the external thread are arranged to match each other.

[0069] Specifically, in this embodiment, the second limiting member 500 and the rotating member 300 are engaged through the second internal thread in the third through hole and the external thread on the rotating member 300. At this time, the first through hole 110 on the moving member 100 may not be provided with a first internal thread. Thus, by rotating the rotating member 300, the second limiting member 500 is driven to move along the axial direction of the rotating member 300, and then the moving member 100 and the bearing are pushed into the mounting hole 11.

[0070] Specifically, since the moving member 100 is located between the bearing and the wheel, when the rotating member 300 is inserted into the first through hole 110 on the moving member 100, due to the shielding of the bearing and the driving gearbox, the operator cannot directly see the first through hole 110. If a first internal thread is provided in the first through hole 110 and the first through hole 110 is engaged with the rotating member 300, the diameter of the first through hole 110 needs to be matched with the diameter of the rotating member 300. The operator needs to spend a lot of time looking for the first through hole 110, and the work efficiency is relatively low.

[0071] To solve the above problems, in this embodiment, by providing a second limiting member 500 engaged with the rotating member 300, when the rotating member 300 is rotated, the moving member 100 and the bearing can be pushed into the mounting hole 11 by the movement of the second limiting member 500 along the axial direction of the rotating member 300. At this time, it is not necessary for the first through hole 110 to be engaged with the rotating member 300. Thus, the diameter of the first through hole 110 can be larger than the diameter of the rotating member 300, which is convenient for the insertion of the rotating member 300 and improves the work efficiency of the operator.

[0072] In addition, in this embodiment, to prevent the second limiting member 500 from rotating synchronously with the rotating member 300, the operator can hold the second limiting member 500 by hand to limit the rotation of the second limiting member 500. When the size of the second limiting member 500 is small and not convenient for the operator to hold, the second limiting member 500 can be bonded to the moving member 100, or matching clamping portions can be provided on the moving member 100 and the second limiting member 500 to clamp the second limiting member 500 and the moving member 100 together. Thus, the operator can avoid the rotation of the second limiting member 500 by directly holding the moving member 100.

[0073] At the same time, it should be noted that this embodiment does not impose any restrictions on the connection manner between the second limiting member 500 and the rotating member 300. The operator can adaptively select the connection manner between the second limiting member 500 and the rotating member 300 according to needs. In addition, the operator can also adopt other ways to limit the rotation of the second limiting member 500 or the moving member 100, and this embodiment does not impose any restrictions on this.

[0074] In an alternative embodiment, a fourth through-hole is formed in the first limiting member 400, and the rotating member 300 is inserted into the fourth through-hole. A third internal thread is provided on the fourth through-hole, and an external thread is provided on the rotating member 300. The third internal thread and the external thread are arranged to match each other.

[0075] Specifically, in this embodiment, the first limiting member 400 and the rotating member 300 are engaged with each other through the third internal thread on the fourth through-hole and the external thread on the rotating member 300. At this time, by screwing the first limiting member 400 onto the rotating member 300, the first limiting member 400 is abutted against the fixing member 200, so that the fixing of the first limiting member 400 and the fixing member 200 can be realized through the thread engagement between the first limiting member 400 and the rotating member 300.

[0076] In actual operation, when the first limiting member 400 abuts against the fixing member 200, at this time, if the first limiting member 400 is continuously screwed, due to the obstruction of the fixing member 200, the first limiting member 400 cannot continue to move along the axial direction of the rotating member 300. Therefore, by continuously screwing the first limiting member 400, the first limiting member 400 and the rotating member 300 can be driven to rotate synchronously, and then the moving member 100 can be driven to push the bearing into the mounting hole 11.

[0077] By making the first limiting member 400 and the rotating member 300 in threaded cooperation, when the operator rotates the rotating member 300, there is no need to continuously apply a force to the first limiting member 400 towards the fixing member 200, and the axial displacement of the rotating member 300 can be restricted through thread engagement, thereby reducing the installation difficulty of the operator and greatly improving the installation efficiency of the operator. At the same time, by adopting the installation method of threaded cooperation, the disassembly efficiency can also be improved when disassembling the installation structure of the part to be installed.

[0078] In an alternative embodiment, the installation structure of the part to be installed further includes a gasket, and the gasket is sleeved on the rotating member 300 and is located between the first limiting member 400 and the fixing member 200.

[0079] Specifically, in this embodiment, the gasket is arranged between the first limiting member 400 and the fixing member 200, so that the contact area between the first limiting member 400 and the fixing member 200 can be increased, the pressure received by the fixing member 200 can be dispersed, and the problem of excessive local pressure caused by too small contact area can be avoided.

[0080] Meanwhile, since the surfaces of the fixing member 200 and the first limiting member 400 are not completely flat, there may be a gap between the first limiting member 400 and the fixing member 200. When affected by vibrations or other external factors, the first limiting member 400 may become loose. By providing a gasket, the gap between the first limiting member 400 and the fixing member 200 can be compensated, ensuring the tightness and stability of the connection between the first limiting member 400 and the fixing member 200.

[0081] In an alternative embodiment, the moving member 100 has a positioning portion for mounting the member to be mounted 20.

[0082] Specifically, in this embodiment, a positioning portion is provided on the moving member 100. When the operator abuts the moving member 100 against the bearing, the moving member 100 can be positioned through the positioning portion, thereby ensuring that the moving member 100 can be located at the center of the bearing, applying a uniform driving force to the bearing, and ensuring the installation effect of the bearing.

[0083] Specifically, the positioning portion can be a convex structure, and the convex structure is correspondingly arranged with the inner ring of the bearing, so that the moving member 100 can be hooked on the bearing, eliminating the need for the operator to always hold the moving member 100. Furthermore, when installing the rotating member 300, the rotating member 300 can accurately find the first through hole 110.

[0084] In other embodiments, the positioning portion can also be other structures capable of achieving positioning. When the member to be mounted 20 is other structures that need to be installed, the positioning portion can be adaptively set to a structure matching the member to be mounted 20, and this embodiment does not impose any restrictions on this.

[0085] In an alternative embodiment, the number of rotating members 300 is at least two, and the first through hole 110, the second through hole 210, and the first limiting member 400 are all arranged in one-to-one correspondence with the rotating members 300.

[0086] Specifically, in this embodiment, the number of rotating members 300 is three. Correspondingly, the number of the first through holes 110, the second through holes 210, and the first limiting members 400 are all three. Among them, the three first through holes 110 are evenly and spacedly arranged on the circumferential side of the moving member 100, the three second through holes 210 are arranged in one-to-one correspondence with the three first through holes 110, and the three rotating members 300 respectively pass through the corresponding three groups of through holes.

[0087] Specifically, when the number of rotating members 300 is multiple, when one of the rotating members 300 is rotated, due to the limitation of the other rotating members 300, the moving member 100 will not rotate synchronously with the rotation of the rotating member 300, so that the operator does not need to always hold the moving member 100 by hand, and the axial displacement of the moving member 100 can be achieved.

[0088] Among them, it should be noted that when one of the rotating members 300 is rotated, due to the limitation of the other rotating members 300, the moving member 100 can only make a slight offset along the axial direction of the rotating member 300. At this time, in order to avoid excessive offset causing the rotating member 300 and the moving member 100 to break under force, the operator can adopt a triangular screwing method, rotating only one of the rotating members 300 one week or half a week each time, so as to realize the pushing and installation of the bearing.

[0089] In other embodiments, the number of the rotating members 300 can also be adaptively selected according to actual needs, and this embodiment does not impose any restrictions on this.

[0090] In an alternative embodiment, the installation structure of the to-be-installed part further includes a first protective member, which is arranged on the fixing member 200 and is used for abutting against the target device 10.

[0091] Specifically, since it is necessary to keep the first limiting member 400 always abutting against the fixing member 200 when rotating the rotating member 300, in order to avoid rigid collision between the fixing member 200 and the target device 10 or damage to the target device 10 due to excessive pressure during the rotation process, therefore, in this embodiment, the installation structure of the to-be-installed part further includes a first protective member, which is arranged on the fixing member 200 and abuts against the target device 10, that is, on the driving gearbox, so as to protect the fixing member 200 and the driving gearbox and avoid damage to the driving gearbox.

[0092] Among them, the first protective member can be a rubber layer, bonded to the fixing member 200, or other materials that can avoid rigid collision, and this embodiment does not impose any restrictions on this.

[0093] In an alternative embodiment, the installation structure of the to-be-installed part further includes a second protective member, which is arranged on the moving member 100 and is used for abutting against the to-be-installed part 20.

[0094] Specifically, since it is necessary to keep the moving member 100 abutting against the to-be-installed part 20 and pushing the to-be-installed part 20 when rotating the rotating member 300, in order to avoid damage to the to-be-installed part 20 due to excessive pressure between the moving member 100 and the to-be-installed part 20 during the rotation process, therefore, in this embodiment, the installation structure of the to-be-installed part further includes a second protective member, which is arranged on the moving member 100 and abuts against the to-be-installed part 20, that is, on the bearing, so as to protect the moving member 100 and the bearing and avoid damage to the bearing.

[0095] Among them, the second protective member can be a rubber layer, bonded to the moving member 100, or other materials that can avoid hard contact, and this embodiment does not impose any restrictions on this.
