For those of ordinary skill in the art, without creative efforts, other drawings can be obtained based on these drawings, and other embodiments can also be obtained.
[0028] See Figure 1 , Figure 2 , Figure 3 and Figure 4 , in this embodiment, a conical roller bearing clearance adjustment tooling is disclosed, which includes a support shaft 1, a sleeve 2, and a locking ring 3. The sleeve 2 is sleeved around the periphery of the support shaft 1. A first tapered bearing 4 and a second tapered bearing 5 are sleeved on the support shaft 1 from top to bottom. At the same time, the first tapered bearing 4 and the second tapered bearing 5 are also located between the support shaft 1 and the sleeve 2. The locking ring 3 is locked at the top of the sleeve 2 and abuts against the upper surface of the outer ring of the first tapered bearing 4. An inner ring spacer 6, an outer ring spacer 7, a bearing adjustment pad 8, and a snap ring 9 are provided between the first tapered bearing 4 and the second tapered bearing 5.
[0029] The sleeve 2 includes a cylindrical part 21 and a support part 22 located at the bottom end of the cylindrical part 21. The support part 22 is an annular flange horizontally extending inward from the inner surface of the cylindrical part 21. The cylindrical part 21 includes a receiving section 211 for placing the bearing and a recessed section 212 located at the top of the receiving section 211. The inner surface of the recessed section 212 is provided with threads, and the support part 22 is arranged at the bottom of the receiving section 211.
[0030] The support shaft 1 includes a shaft body 11 and a base 12 located at the bottom of the shaft body 11. The locking ring 3 includes a connecting part 31 for threaded connection with the recessed section 212 and a boss part 32 radially extending outward from the connecting part 31. The boss part 32 is located above the connecting part 31. The bottom surface of the connecting part 31 presses against the upper surface of the outer ring of the first tapered bearing 4.
[0031] The inner ring spacer 6 is located above the inner ring of the second tapered bearing 5, and the bearing adjustment pad 8 is located between the inner ring spacer 6 and the inner ring of the first tapered bearing 4. The outer ring spacer 7 is located above the outer ring of the second tapered bearing 5, and the snap ring 9 is located between the outer ring spacer 7 and the outer ring of the first tapered bearing 4.
[0032] The bottom surface of the inner ring of the second tapered bearing 5 is supported on the base 12, and the lower surface of the outer ring of the second tapered bearing 5 is supported on the support part 22. A circular groove 2111 is provided in the middle of the inner wall of the receiving section 211, and the snap ring 9 is arranged in the circular groove 2111. The inner ring spacer 6 is radially provided with a plurality of oil through holes 61 for lubricating the shaft sleeved during installation.
[0033] During assembly, first place the support shaft 1 on the working platform, then slip the inner ring of the second tapered bearing 5 (with tapered rollers installed therein) onto the support shaft 1, and then successively slip the inner ring spacer 6 and the bearing adjusting pad 8 onto the support shaft 1. Place the outer ring of the second tapered bearing 5 into the sleeve 2, and then successively place the outer ring spacer 7, the snap ring 9, and the outer ring of the first tapered bearing 4. Finally, screw the locking ring 3 tightly onto the sleeve 2 and press the outer ring of the first tapered bearing 4. Among them, when the snap ring 9 falls into the annular groove 2111, it expands outward and snaps into the annular groove 2111. At this time, slip the assembled sleeve 2 onto the assembled support shaft 1, and then slip the inner ring of the first tapered bearing 4 (with tapered rollers installed therein) onto the support shaft 1. In this embodiment, the side of the shaft body 11 opposite to the base 12 is provided with threads. By screwing the locking nut 10 into the shaft body 11, pressure is applied to the inner ring of the first tapered bearing 4, so as to press the inner ring of the first tapered bearing 4 tightly against the bearing adjusting pad 8. Then align the dial indicator with the upper surface of the locking ring 3, axially move the sleeve 2 up and down, observe the dial indicator, and measure the actual bearing clearance. If the clearance does not meet the standard, unscrew the locking nut 10, remove the inner ring of the first tapered bearing 4 or lift the entire sleeve 2, replace the bearing adjusting pad 8 with a suitable thickness, then screw the locking nut 10 tightly and measure again until the clearance is within the specified value range. After the clearance meets the requirements, package the complete set of bearings, inner and outer spacers, adjusting pads, and the snap ring 9 in groups and transfer them as a complete set to the subsequent installation station.
[0034] In other embodiments, a press or additional tooling can be used to press the inner ring of the first tapered bearing 4 tightly, fix it on the horizontal working platform, and then use measuring tools such as a dial indicator to measure the movable distance of the sleeve 2 to obtain the actual bearing clearance.
[0035] The tapered bearing clearance adjustment tooling of this embodiment can pre-assemble a set of tapered roller bearing parts to be installed in the clearance adjustment tooling at the corresponding positions, simulate the conditions of each installation position, and then continuously adjust the thickness of the bearing adjusting pad 8, so as to ensure that the clearance of this set of parts is reasonable, and then use the whole set for subsequent component installation.
[0036] When using this clearance adjustment tooling, the greatest advantage is that it can ignore the previous measurement data, or ignore the cumulative error of the previous measurement data, and start the measurement with a bearing adjusting pad 8 with a roughly calculated thickness. After replacing the bearing adjusting pad 8 with a suitable thickness according to the measured actual clearance, verify it again. During the use process, since the cooperation between the support shaft 1 and the sleeve 2 of the clearance adjustment tooling and the first tapered bearing 4 and the second tapered bearing 5 can be appropriately set as a clearance fit, the loss of parts can be reduced as much as possible during disassembly and assembly. In addition, when replacing the bearing adjusting pad 8, there is no need to loosen the locking ring 3, and only the entire sleeve 2 needs to be lifted to directly replace it. The transfer of the whole set of parts to the subsequent station is also more suitable for the requirements of assembly line assembly.
[0037] It will be apparent to those skilled in the art that various modifications and variations can be made to the above-described exemplary embodiments of the present invention without departing from the spirit and scope of the present invention. Accordingly, it is intended that the present invention cover modifications and variations of the present invention falling within the scope of the appended claims and their equivalent technical solutions.
