Abstract
Description
Technical Field
[0001] This invention relates to the field of bearings, and in particular to a magnetic retaining ring removal device for locomotive wheel bearings. Background Technology
[0002] Locomotive wheel bearings are among the most important components ensuring the safe operation of locomotives. Their main function is to support the locomotive wheel axle, reduce the coefficient of friction during its movement, and ensure its rotational accuracy. During high-speed operation of a locomotive, the locomotive wheel bearings bear enormous loads and centrifugal forces, making their installation, lubrication, sealing, and clearance adjustment extremely critical.
[0003] When bearings are used in conjunction with locomotive wheel bearings, lubricating oil is usually added to the bearings to reduce resistance and extend their service life. During high-speed rotation of the shaft, the lubricating oil will be flung out by centrifugal force. Therefore, a special retaining ring needs to be fitted to the exposed side of the bearing to prevent further leakage.
[0004] When in use, the retaining ring needs to be coaxially installed on the locomotive wheel axle together with the bearing. In order to maintain stability, the retaining ring is usually interference-fitted with the locomotive wheel axle. When replacing or disassembling, it is necessary to use hard tools to remove it forcefully, which can easily cause damage and deformation to the retaining ring, or even damage the surface of the locomotive wheel axle, causing greater losses. Summary of the Invention
[0005] Therefore, it is necessary to provide a magnetic retaining ring removal device for locomotive wheel bearings that facilitates the replacement and removal of retaining rings on locomotive axles, in order to address the aforementioned technical problems.
[0006] A magnetic retaining ring removal device for locomotive wheel bearings includes a conductive ring, a conductive disk, a mounting base, and an adsorption assembly. The conductive ring and the mounting base are respectively fixed on both sides of the conductive disk. The conductive ring can be attached to the retaining ring. The adsorption assembly is installed in the mounting base and can rotate within the mounting base to adjust the orientation of the adsorption end of the adsorption assembly.
[0007] Furthermore, the adsorption assembly includes a magnetic suction element, a housing, connecting rods, and a rocker assembly; the housing is wrapped around the surface of the magnetic suction element, and a portion of the magnetic suction element is exposed to form an adsorption end; the two connecting rods are coaxially arranged with the housing and respectively fixed at both ends of the housing; the connecting rods are rotatably mounted on the mounting base, with one end located outside the mounting base, and the rocker assembly is mounted on that end.
[0008] Furthermore, the rocker assembly includes a sleeve, a fixing tube, and a pressing rod; the sleeve is movably sleeved on one end of the connecting rod located outside the mounting base, the fixing tube is fixed on the sleeve, and the two are internally connected, the pressing rod is snapped into the fixing tube, and the ends of the two are elastically connected by a spring, and one end of the pressing rod can be snapped into a groove on the connecting rod.
[0009] Furthermore, the rocker assembly also includes positioning rods, and multiple rocker rods are arranged circumferentially around the connecting rod and fixed on the mounting base. The pressing rod has a horizontal groove and a vertical groove on the side facing the positioning rod. When the pressing rod is pressed, the vertical groove and the positioning rod are engaged with each other, and one end of the pressing rod is engaged in the groove. At this time, rotating the fixing tube can drive the connecting rod to rotate, and the horizontal groove will pass over multiple positioning rods in sequence.
[0010] Furthermore, the outer shell is configured as a circular cylindrical structure, with a hollow interior for mounting the magnetic component. An opening is provided on the outer circumference of the outer shell, and the magnetic component has an adsorption end located at one of the openings.
[0011] Furthermore, the two ends of the opening are on the same plane as the two ends inside the outer shell, and the two sides of the opening form an opening between each other.
[0012] Furthermore, the opening is aligned with the central axis of the rocker arm. When the rocker arm is perpendicular to the transmission disk, the opening faces the transmission disk. When the rocker arm is parallel to the transmission disk, the opening and the transmission disk are separated by the outer shell.
[0013] Furthermore, the size of the opening is 1 / 4 of the outer shell.
[0014] Furthermore, the outer shell is made of a non-magnetic material.
[0015] Furthermore, the portion of the conductive ring and the conductive disk that is in contact with the conductive ring is made of a magnetically conductive material.
[0016] The aforementioned magnetic retaining ring removal device for locomotive wheel bearings installs a transmission ring and an adsorption assembly on opposite sides of a transmission disk, with the transmission ring fitting against the retaining ring. The adsorption end of the adsorption assembly can be rotated and adjusted to face the transmission disk, thus achieving the effect of adsorbing the device onto the retaining ring. When removing the retaining ring, only force needs to be applied to detach it from the bearing, eliminating the need for tools for disassembly and assembly, thereby avoiding damage to the retaining ring and making disassembly and assembly more convenient.

Detailed Implementation
[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0025] like Figure 1 and Figure 2 As shown, in one embodiment, a locomotive wheel bearing magnetic retaining ring removal device includes a conduction ring 100, a conduction disk 200, a mounting base 300, and an adsorption assembly 400; the conduction ring 100 and the mounting base 300 are respectively fixed on both sides of the conduction disk 200, the conduction ring 100 can fit against the retaining ring, the adsorption assembly 400 is installed in the mounting base 300, and the adsorption assembly 400 can rotate in the mounting base 300, thereby adjusting the orientation of the adsorption end of the adsorption assembly 400.
[0026] In use, the end of the conduction ring 100 is aligned with the outer retaining ring of the locomotive bearing to facilitate subsequent removal of the retaining ring. Initially, the adsorption end of the adsorption assembly 400 is not facing the conduction disk 200. When the conduction ring 100 is aligned with the corresponding position on the retaining ring, the adsorption assembly 400 is rotated so that the adsorption end of the adsorption assembly 400 faces the conduction disk 200. This adsorption end is then adsorbed onto the retaining ring through the conduction disk 200 and the conduction ring 100. Applying force allows the retaining ring to be removed without the need for disassembly tools.
[0027] The aforementioned magnetic retaining ring removal device for locomotive wheel bearings installs the conduction ring 100 and the adsorption component 400 on both sides of the conduction disk 200, with the conduction ring 100 attached to the retaining ring. The adsorption end of the adsorption component 400 can be rotated and adjusted to face the conduction disk 200, thus achieving the effect of adsorbing the device onto the retaining ring. When removing the retaining ring, only force needs to be applied to detach the retaining ring from the bearing, without the need for tools to assist in disassembly and assembly, thereby avoiding damage to the retaining ring and making disassembly and assembly more convenient.
[0028] like Figures 3 to 6 As shown, in this embodiment, the adsorption assembly 400 includes a magnetic suction element 410, a housing 420, a connecting rod 430, and a rocker assembly 440. The housing 420 wraps around the surface of the magnetic suction element 410, and the partial exposure of the magnetic suction element 410 forms the adsorption end. The two connecting rods 430 are coaxially arranged with the housing 420 and respectively fixed at both ends of the housing 420. The connecting rods 430 are rotatably mounted on the mounting base 300, and one end of the connecting rod is located outside the mounting base 300. The rocker assembly 440 is mounted on this end.
[0029] The connecting rod 430 and the rocker assembly 440 together form an L-shaped drive component. One end of the drive component is hinged to the mounting base 300 and fixedly connected to the housing 420, while the other end is located outside the mounting base 300 for the user to operate.
[0030] The aforementioned rocker assembly 440 includes a sleeve 441, a fixing tube 442, and a pressing rod 443. The sleeve 441 is movably sleeved on one end of the connecting rod 430 outside the mounting base 300. The fixing tube 442 is fixed to the sleeve 441, and the two are internally connected. The pressing rod 443 is snapped into the fixing tube 442, and the ends of the two are elastically connected by a spring 444. One end of the pressing rod 443 can be snapped into the slot 431 on the connecting rod 430. In use, the pressing rod 443 needs to be pressed so that its end is snapped into the slot 431 on the connecting rod 430. Then, the fixing tube 442 can be rotated to adjust the adsorption end of the magnetic attractor 410. After adjustment, the pressing rod 443 is stopped, and the end of the pressing rod 443 disengages from the slot 431. After this, even if the fixing tube 442 is accidentally touched, it will not affect the adsorption end of the magnetic attractor 410.
[0031] The aforementioned rocker assembly 440 also includes positioning rods 450, which are arranged circumferentially around the connecting rod 430 and fixed on the mounting base 300. The pressing rod 443 has a horizontal groove 445 and a vertical groove 446 on the side facing the positioning rod 450. When the pressing rod 443 is pressed, the vertical groove 446 and the positioning rod 450 are engaged with each other, and one end of the pressing rod 443 is engaged in the slot 431. At this time, rotating the fixing tube 442 can drive the connecting rod 430 to rotate, and the horizontal groove 445 will pass over the multiple positioning rods 450 in sequence. When the pressing rod 443 is pressed, the vertical groove 446 and a positioning rod 450 will move relative to each other. That is, the positioning rod 450 moves from one end of the vertical groove 446 into the horizontal groove 445. At this time, the end of the pressing rod 443 is also engaged in the slot 431. When the fixed tube 442 is rotated, the trajectory of the horizontal groove 445 forms an annular space. Multiple positioning rods 450 are located in this annular space. After the rotation is completed, the pressing rod 443 is stopped. Affected by the spring 444, the pressing rod 443 pops out of the slot 431, and the vertical groove 446 moves along a positioning rod 450 and finally fits on the positioning rod 450. On the one hand, it prevents the connecting rod 430 from rotating due to accidental contact, and on the other hand, it also prevents the fixed tube 442 from rotating.
[0032] In this embodiment, the outer shell 420 is a circular cylindrical structure with a hollow interior for mounting the magnetic component 410. An opening 421 is formed on the outer periphery of the outer shell 420, and the magnetic component 410 has an adsorption end located at one of the openings 421. The regular structure of the outer shell 420 reduces its space requirement during rotation and allows for a more compact arrangement of components within the mounting base 300. The two ends of the opening 421 are on the same plane as the two ends inside the outer shell 420, forming an open section between the two sides of the opening 421. Maximizing the size of the opening 421 increases the exposed area of the magnetic component 410, thereby increasing the magnetic adsorption force.
[0033] In this embodiment, the opening faces the same direction as the central axis of the rocker arm. When the rocker arm is perpendicular to the transmission disk 200, the opening faces the transmission disk 200. When the rocker arm is parallel to the transmission disk 200, the opening and the transmission disk 200 are separated by the outer shell 420. Alternatively, the opening can also be perpendicular to the central axis of the rocker arm. When the rocker arm is parallel to the transmission disk 200, the opening faces the transmission disk 200. When the rocker arm rotates to be perpendicular to the transmission disk 200, the opening faces the original position of the rocker arm, and at this time, the opening and the transmission disk 200 are separated by the outer shell 420. By aligning the opening with the central axis of the rocker arm, when the rocker arm is perpendicular to the transmission disk 200, regardless of which direction it rotates, the opening and the transmission disk 200 are separated by the outer shell 420, thus making the device more standardized and allowing normal use regardless of the installation direction.
[0034] The size of the opening is 1 / 4 of the outer shell 420. This effectively balances the opening's expansion range and the contact area with the conduction disk 200 during adsorption and non-adsorption. It should be noted that the size of the opening can be adjusted according to the actual structural size of each component within the device.
[0035] In this embodiment, the outer casing 420 is made of a material capable of isolating magnetism. This prevents the magnetic suction element 410 from releasing magnetic force in other directions, thus ensuring that the adsorption assembly 400 has an adsorption end. The portions of the conductive ring 100 and the conductive disk 200 that are in contact with the conductive ring 100 are made of a magnetically conductive material. A handle 500 is also installed on the aforementioned mounting base 300, making it more convenient to pick up and remove the device.
[0036] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
