[0002] Compared with the subway, the monorail train has the advantages of small noise, comfortable ride, high running, strong climbing ability, small turning radius, less restriction on line conditions, etc., and is suitable for scenic spots and small and medium-sized traffic lines, and has a wide market prospect.
[0003] As an important component for stable operation of the monorail train, the bearing clearance of the horizontal wheel during assembly will have an important influence on the vehicle running stability, bearing service life, and running noise.
[0004] The bearing clearance refers to the movement amount of one of the inner ring or the outer ring of the bearing when the one is fixed and the other is moved radially or axially when the bearing is not installed on the shaft or the bearing box.

[0063] The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings. Figures 1-7 The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings.
[0064] In the description of the present application, it should be understood that the terms "upper", "lower", "top surface", "bottom surface" and the like indicate the orientation or positional relationship shown in the drawings, and are only used for the purpose of facilitating the description of the present application and simplifying the description, and do not indicate or imply that the position or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the present application. In addition, the terms "first", "second" are only used for the purpose of description, and cannot be understood as indicating or implying relative importance.
[0065] As Figures 1-6The horizontal wheel bearing clearance adjusting device disclosed by the present application is used for adjusting the bearing clearance of a horizontal wheel, which comprises a first bearing 100, a wheel hub 101, a spacer sleeve 102, a second bearing 103 and other components, and the horizontal wheel bearing clearance adjusting device comprises a base 200, a mounting shaft 300, a lifting tool 400, a locking nut 500, a dial gauge 600 and a magnetic dial gauge seat, wherein the base 200 is a cuboid structure, the mounting shaft 300 is arranged eccentrically on the base 200, the first bearing 100, the wheel hub 101, the spacer sleeve 102 and the second bearing 103 are arranged on the mounting shaft 300 in sequence from top to bottom, the locking nut 500 is arranged on the top of the mounting shaft 300 and used for locking the first bearing 100, the lifting tool 400 is connected with the wheel hub 101 and used for lifting the wheel hub 101, the magnetic dial gauge seat is connected with the dial gauge 600 and used for fixing the dial gauge 600 on the wheel hub 101, and the dial gauge 600 is used for recording the maximum circular runout value between the wheel hub 101 and the base 200.
[0066] Specifically, in order to make the circular runout measurement value of the dial gauge 600 more in line with the actual value, the base 200 needs to be lifted to simulate the load borne by the bearing during actual work of the horizontal wheel, and the wheel hub 101 needs to be rotated multiple times in the lifted state, because the bearing clearance value is finally fed back to the circular runout value of the wheel hub 101 relative to the shaft during operation of the horizontal wheel, so the maximum deviation value, i.e. the maximum circular runout measurement value, is measured by using the dial gauge 600, and after conversion, it can be confirmed whether the deviation value is within the evaluation standard value range of the bearing clearance value, so as to determine whether the actual clearance value after bearing assembly meets the use requirement.
[0067] In use, the first bearing 100, the wheel hub 101, the spacer sleeve 102 and the second bearing 103 are arranged in sequence from top to bottom on the mounting shaft 300, and the first bearing 100 is fixed by using the lock nut 500, then the hoist 400 hoists the mounting shaft 300 until the base 200 is in an inclined state, the dial gauge 600 is zeroed, the operator repeatedly rotates the wheel hub 101 and then reads the reading value of the dial gauge 600, the reading value is compared with the evaluation standard value, if the value is qualified, the first bearing 100, the wheel hub 101, the spacer sleeve 102 and the second bearing 103 are disassembled, if the value is greater than the evaluation standard value, the spacer sleeve 102 is replaced by a lengthened spacer sleeve and is re-measured, and if the value is less than the evaluation standard value, the spacer sleeve 102 is shortened and is re-measured. By making the base 200 in an inclined state and by matching the wheel hub 101, the spacer sleeve 102, the first bearing 100 and the second bearing 103 through the mounting shaft 300 and the lock nut 500, the actual installation environment of the horizontal wheel is simulated, so that the actual clearance value of the bearing assembly is measured, and the actual clearance value is adjusted by adjusting the length of the spacer sleeve 102. When the reading value meets the evaluation standard value, the first bearing 100, the wheel hub 101, the spacer sleeve 102 and the second bearing 103 are disassembled from the mounting shaft 300 and are marked for use on the same horizontal wheel, when the reading value is greater than the evaluation standard value, the spacer sleeve 102 is replaced by a lengthened spacer sleeve and is re-measured, and when the reading value is less than the evaluation standard value, the size of the spacer sleeve 102 is reduced by grinding and is re-measured. In summary, the actual clearance value of the bearing assembly can be measured, and it is judged whether the actual clearance value is within the evaluation standard value range of the bearing clearance value, so that whether the actual clearance value of the bearing assembly meets the use requirement is determined, and the actual clearance value of the bearing assembly is adjusted.
[0068] In order to optimize the above technical scheme, the base 200 comprises a workbench 201 and a nylon foot 202, wherein the mounting shaft 300 is arranged eccentrically on the workbench 201, and the nylon foot 202 is arranged at the bottom of the workbench 201 and used for protecting the workbench 201 and the ground on which the workbench 201 is located. Specifically, the material of the workbench 201 comprises but is not limited to steel, wood and the like, and in the present application, the workbench 201 is preferably made by welding a steel plate and a steel pipe, and the bottom of the steel pipe is connected with the nylon foot 202. Because the base 200 needs to fall on the ground for many times when the horizontal wheel bearing play adjusting device is working, the nylon foot 202 is arranged to avoid damage to the ground when the base 200 falls on the ground when the horizontal wheel bearing play adjusting device is working, and to protect the base 200 and improve the service life thereof. Because the workbench 201 has a rectangular structure and needs to be inclined and lifted when in use, the mounting shaft 300 is fixed eccentrically on the workbench 201. Specifically, the overall weight of the base 200 is designed according to the actual working load of the horizontal wheel. When the base 200 is lifted, only one side of the base 200 is in contact with the ground, that is, linear contact with the ground, and the whole is in an inclined state to simulate the actual working load of the horizontal wheel and expand the measurement, so as to ensure the measurement accuracy.
[0069] In order to optimize the above technical scheme, the mounting shaft 300 comprises a mounting disc 301, a shaft body 302 and a first flange plate 303, wherein the first bearing 100, the hub 101, the spacer sleeve 102 and the second bearing 103 are sequentially arranged on the shaft body 302 from top to bottom, the mounting disc 301 is arranged perpendicularly to the shaft body 302 and fixed eccentrically on the base 200, and the first flange plate 303 is arranged at one end of the mounting shaft 300 close to the second bearing 103 and used for limiting the second bearing 103. The size of the shaft body 302 above the first flange plate 303 is consistent with the size of the mounting shaft 300 of the horizontal wheel. Specifically, the mounting disc 301 is fixed to the workbench 201, and the fixing mode of the mounting disc 301 to the workbench 201 comprises but is not limited to bolt connection, welding and the like. The size of the shaft body 302 above the first flange plate 303 is consistent with the size of the mounting shaft 300 of the horizontal wheel, which can make the measured play values of the first bearing 100 and the second bearing 103 more consistent with the actual play values in working, so as to determine whether the actual play values of the bearings after assembly meet the use requirements.
[0070] In use, the mounting disc 301 is connected with the shaft body 302, the mounting disc 301 is fixed to the workbench 201, then the first flange plate 303 is arranged on the top of the shaft body 302, and the first bearing 100, the hub 101, the spacer sleeve 102 and the second bearing 103 are sequentially arranged on the shaft body 302 from top to bottom, and the first flange plate 303 limits the second bearing 103. Such arrangement can make the horizontal wheel bearing play adjusting device work closer to the actual working condition of the horizontal wheel, so as to measure a reading value closer to the actual play value.
[0071] In order to optimize the above technical solutions, the lifting appliance 400 comprises a hook 401, a second flange plate 402 and three lifting rods 403, wherein the hook 401 is arranged at the middle of the second flange plate 402, the second flange plate 402 can rotate relative to the hook 401, the first ends of the three lifting rods 403 are uniformly fixed to the edges of the second flange plate 402, and the second ends of the three lifting rods 403 are connected with the wheel hub 101, and the lifting rods 403 are used to lift the wheel hub 101. Specifically, the middle of the second flange plate 402 is arranged with a hook hole, after the bottom of the hook 401 is inserted into the hook hole, the bottom of the hook 401 is fixed by using a flat washer 4011 and a fixing nut 4012, the hook 401 can rotate relative to the second flange plate 402, and the material of the second flange plate 402 comprises but is not limited to steel and iron. In use, the second ends of the lifting rods 403 are connected with the wheel hub 101, then the hook 401 is hung on the lifting device, the lifting device simultaneously lifts the lifting appliance 400, the mounting shaft 300 and the base 200, until one side of the base 200 leaves the ground and the other side is still on the ground, the base 200 is in an inclined state as a whole, then the operator repeatedly rotates the wheel hub 101 multiple times, at this time only the wheel hub 101, the second flange plate 402 and the lifting rods 403 rotate, and the hook 401 is relatively static, then the reading value of the dial gauge 600 is read, after the measurement is completed, the lifting device simultaneously lowers the lifting appliance 400, the mounting shaft 300 and the base 200, and after the base 200 slowly falls to the ground, the operator unloads the lifting appliance 400 from the wheel hub 101.
[0072] Specifically, because the second flange plate 402 can rotate relative to the hook 401, the lifting rods 403 can be at any angle in the vertical direction, and when the base 200 is in the lifting state, the lifting rods 403 can rotate in the vertical direction at will, so that the operator can carry out measurement of the wheel hub 101 at any position. Such an arrangement can simulate the bearing clearance data of the horizontal wheel in various application states, and improve the use efficiency of the horizontal wheel bearing clearance adjusting device.

In use, according to the needs, the three lifting rods 403 can be arranged in the three mounting holes of the six mounting holes on the wheel hub 101 in a triangular shape.
[0074] Specifically, in actual application, different numbers of lifting rods 403 can be used according to the number of mounting holes of the wheel hub 101, and according to the actual use and matching of most existing wheel hubs 101, the number of lifting rods 403 in the present application is preferably three.
[0075] In use, the second end of the hanger 403 is fixed by a nut after passing through the mounting hole of the wheel hub 101, and the nut includes but is not limited to a hexagonal nut, a self-locking nut, a butterfly nut and the like, because the antler nut can realize the fixation of the second end of the hanger 403 and is easy to obtain, so the hexagonal nut is preferably used to fix the second end of the hanger 403.
[0076] In order to optimize the above technical solution, the first end of the hanger 403 is arranged with a thread, and the second flange plate 402 is arranged with a threaded hole matched with the first end of the hanger 403. In use, the operator rotates the first end of the hanger 403 into the threaded hole to realize the fixation of the hanger 403 and the second flange plate 402. Further, in order to ensure the use effect, after the first end of the hanger 403 is rotated into the threaded hole, a fixing nut can be arranged on the first end of the hanger 403 to further fix the hanger 403.
