Description

Technical Field

[0001] This invention relates to the field of bearings, and more specifically to a tapered roller bearing processing apparatus and its processing technology. Background Technology

[0002] Tapered roller bearings, as separable bearings, consist of an inner ring, outer ring, cage, and multiple tapered rollers. Because they can simultaneously withstand combined radial and axial loads, they are widely used in mechanical transmission. In their manufacturing process, the assembly of multiple tapered rollers into the cage slots is a core step, directly affecting bearing assembly efficiency and product yield. Achieving ease of assembly and preventing detachment in this process has been a long-standing technical focus in the industry. The tapered structure of the rollers makes them prone to detachment during assembly due to unstable positioning. Traditional assembly methods lack dedicated roller limiting mechanisms, allowing rollers to slip out of the tooling or cage during loading due to external forces or their own weight. In summary, existing tapered roller bearing manufacturing technologies, in practical applications, struggle to simultaneously achieve both ease of assembly and anti-detachment stability for multiple tapered rollers. Summary of the Invention

Detailed Implementation

[0016] A tapered roller bearing processing apparatus, wherein the tapered roller bearing includes an outer ring 501, the inner circumference of the outer ring 501 is a tapered surface, the outer circumference of the inner ring 502 is a tapered surface, a tapered raceway 503 is provided on the tapered raceway 503, a plurality of tapered rollers 504 are evenly distributed on the tapered raceway 503, and a spacer 505 is provided between the outer ring 501 and the inner ring 502, the spacer 505 separates the plurality of tapered rollers 504, and the plurality of tapered rollers 504 are in contact with the tapered surface of the outer ring 501; The processing device includes a support ring 201 with an L-shaped cross-section. Multiple protrusions 202 are arranged annularly on the support ring 201. When processing the bearing, the support ring 201 is placed horizontally, the inner ring 502 is placed on the multiple protrusions 202, and the spacer 505 is fitted onto the inner ring 502. The support ring 201 then supports the spacer 505. Multiple tapered rollers 504 are then placed in the multiple through holes on the spacer 505 and inserted into the tapered raceway 503. The outer edge of the support ring 201 supports the multiple tapered rollers 504. Finally, the outer ring 501 is fastened to the outside of the multiple tapered rollers 504, facilitating the assembly and processing of the tapered roller bearing.

[0017] like Figure 4-5 As shown in Figures 10-17; The L-shaped support ring 201 provides horizontal support for the inner ring 502 through the annularly distributed protrusions 202. At the same time, it ensures that the through hole of the isolation frame 505 fitted on the inner ring 502 is precisely aligned with the tapered raceway 503 of the inner ring 502. After the tapered roller 504 is inserted into the through hole, the outer edge of the support ring 201 forms an annular support surface, supporting the tapered roller 504 from the bottom and preventing it from slipping due to gravity caused by the tapered structure. Subsequently, the outer ring 501 can be directly fastened to the outside of the tapered roller 504 to complete the assembly without the need for additional expansion and contraction processes, which greatly improves the convenience of assembling multiple tapered rollers 504.

[0018] The tapered roller bearing also includes an anti-slip ring 506, which is connected to one side of the outer ring 501 by screws. Multiple limiting strips 509 are evenly distributed on the inner circumference of the anti-slip ring 506. The multiple limiting strips 509 block one side of the isolation frame 505. Each limiting strip 509 is fixed with a threaded post 507. An annular cover 508 is inserted into the multiple threaded posts 507 and blocks one side of the multiple tapered rollers 504. Each threaded post 507 is connected with a nut by threads, and the nut presses against the outside of the annular cover 508.

[0019] like Figure 10-17 As shown; After the anti-detachment ring 506 is fixed to the outer ring 501 by screws, the limiting strip 509 on its inner side limits the position of the isolation frame 505 from the side, preventing the isolation frame 505, the inner ring 502 and the multiple tapered rollers 504 from falling off the outer ring 501; the annular cover 508 is locked to the nut by the threaded post 507. The annular cover 508 forms a shield for the multiple tapered rollers 504, and grease can be put between the outer ring 501 and the inner ring 502 to make the bearing run more lubricated. The annular cover 508 prevents grease from overflowing. After the annular cover 508 is removed, grease can be easily added between the outer ring 501 and the inner ring 502.

[0020] A translation column 203 is fixed on the support ring 201. The translation column 203 is slidably connected to the rotating column 405. A fastening screw is threadedly connected to the translation column 203 and presses against the rotating column 405.

[0021] like Figure 4-5 As shown in Figures 8-9; The translation column 203, which is fixed to the support ring 201, can slide along the rotating column 405 to adjust the relative position of the translation column 203 and the rotating column 405. The fastening screws are tightened by thread to achieve relative fixation between the translation column 203 and the rotating column 405. When assembling and machining the bearing, the rotating column 405 is adjusted to a vertical position to facilitate the assembly of the outer ring 501, inner ring 502, multiple tapered rollers 504 and the spacer 505 together in a horizontal position.

[0022] A support bar 104 is fixed to the end of the rotating column 405. The support bar 104 is perpendicular to the rotating column 405. A square column 101 is fixed to the upper end of the support bar 104. Slider blocks 103 are slidably connected to both ends of the square column 101. A motor 106 is fixed to each of the two sliders 103. A cylinder 108 is fixed to the output shaft of each of the two motors 106. A retaining ring 107 is fixed to each cylinder 108. The two cylinders 108 are supported on the inner circumference of the inner ring 502. One side of the inner ring 502 is in contact with the retaining ring 107.

[0023] like Figure 4-5 As shown in Figures 10-17; The two sliders 103 on the square column 101 can drive the cylinder 108 to move closer or further away synchronously. The inner ring 502 is centered and clamped by the contact between the cylinder 108 and the inner circumference of the inner ring 502. The retaining ring 107 on the cylinder 108 forms an axial limit from the end face of the inner ring 502 to prevent the inner ring 502 from moving axially during assembly. When the motor 106 drives the cylinder 108 to rotate, it can drive the inner ring 502 to rotate synchronously, which makes it easy to adjust the position of the horizontal inner ring 502 and the isolation frame 505. The tapered rollers 504 are manually installed on the isolation frame 505. The position of the isolation frame 505 without tapered rollers 504 is turned to the side facing the person, which makes it easy to install all the tapered rollers 504 on the isolation frame 505.

[0024] Both ends of the square column 101 are fixed with side plates 105. The two ends of the double threaded screw 102 are rotatably connected to the two side plates 105 respectively. The two ends of the double threaded screw 102 have opposite thread directions. The two ends of the double threaded screw 102 are respectively engaged with the two sliders 103 through threads.

[0025] like Figure 4-5 As shown; The threads at both ends of the double-threaded screw 102 turn in opposite directions. When the double-threaded screw 102 is rotated, it can drive the two sliders 103 on the square column 101 to slide synchronously in opposite directions, thereby driving the two cylinders 108 to move closer or further away precisely. This structure can quickly clamp the inner ring 502, realize the rapid centering and clamping of the inner ring 502, reduce the clamping and adjustment time, and improve the ease of assembly.

[0026] The end of the rotating column 405 is fixed with a short shaft 409. The front and rear sides of the L-shaped seat 410 are both fixed with bearing seats 402. The two ends of the short shaft 409 are rotatably connected to the two bearing seats 402 respectively. The lower side of the L-shaped seat 410 is fixed with a vertical column 411, which is fixed on the base 401.

[0027] like Figure 8-9 As shown; The rotating column 405 is rotatably connected to the bearing seat 402 of the L-shaped seat 410 via the short shaft 409, allowing the rotating column 405 to rotate around the short shaft 409, thereby driving the support ring 201 and the bearing assembly under assembly to adjust their posture; the L-shaped seat 410 is fixed to the base 401 via the vertical column 411, providing stable support for the entire device and ensuring the safety of the bearing assembly during the rotation process.

[0028] When assembling the outer ring 501, inner ring 502, multiple tapered rollers 504, and spacer 505, the rotating column 405 is rotated to a vertical position, at which point the support ring 201 is placed in a horizontal position. Then, the inner ring 502 is clamped and fixed in a horizontal position by two cylinders 108. Then, the translation column 203 and the support ring 201 are driven to move upward along the rotating column 405, so that the support ring 201 supports the inner ring 502, multiple tapered rollers 504, and spacer 505. After the multiple tapered rollers 504 are mounted on the spacer 505, the outer ring 501, which is pre-set above the inner ring 502, can be fastened to the outside of the multiple tapered rollers 504, completing the basic assembly of the tapered roller bearing. Then, when assembling the anti-slip ring 506 and the annular cover 508 onto the tapered roller bearing, rotate the rotating column 405 to a horizontal position and manually squeeze grease between the outer ring 501 and the inner ring 502. The grease, through its viscosity, binds the outer ring 501, inner ring 502, tapered roller 504, and spacer 505 together. At this point, the outer ring 501, inner ring 502, tapered roller 504, and spacer 505 will not fall off. Then, manually slide the support ring 201 to the right and the translation column 203 so that the support ring 201 leaves the tapered roller bearing. Then, manually connect the anti-slip ring 506 to one side of the outer ring 501 with screws. Multiple limit strips 509 block one side of the spacer 505. Then, insert the annular cover 508 onto multiple threaded columns 507 and screw a nut into each threaded column 507 so that the nut presses against the outside of the annular cover 508, completing the overall assembly of the tapered roller bearing.

[0029] A front bar 403 is fixed on the base 401. A pull post 406 is slidably connected to the upper part of the front bar 403 in the front-back direction. A pull tab 404 is fixed to the front part of the pull post 406. A connecting strip 407 is fixed to the rear part of the pull post 406. Two fixing forks 408 are fixed on the connecting strip 407. A compression spring is sleeved on the pull post 406. The compression spring is located between the front bar 403 and the connecting strip 407. When the two fixing forks 408 are inserted into the rotating post 405, they can fix the rotating post 405 in a horizontal and vertical state, respectively.

[0030] like Figure 8-9 As shown; The compression spring provides a continuous backward elastic force to the pull column 406, causing the fixing fork 408 on the connecting bar 407 to always be in contact with the rotating column 405. When the rotating column 405 is flipped to a horizontal or vertical position, the fixing fork 408 at the corresponding position will automatically insert into the positioning groove of the rotating column 405 under the action of the spring, realizing the quick locking of the rotating column 405 and avoiding accidental flipping during assembly. Pulling the pull tab 404 can drive the pull column 406 to slide forward, causing the fixing fork 408 to disengage from the positioning groove, unlocking the rotating column 405 to adjust its posture. The operation is convenient and the locking is stable.

[0031] The middle part of the horizontal column 301 is slidably connected to the rotating column 405. The middle part of the horizontal column 301 is connected to a fastening screw by a thread. The fastening screw presses on the rotating column 405. Both the front and rear ends of the horizontal column 301 are slidably connected to L-shaped frames 304. Each L-shaped frame 304 is fixed with a V-shaped clamp 305. A protrusion 306 is fixed on one side of the V-shaped clamp 305.

[0032] like Figure 6-9 As shown; The horizontal column 301 can slide along the rotating column 405 and be fixed by fastening screws. When the two L-shaped brackets 304 approach each other, they drive the two V-shaped clamps 305 to approach each other, and then the outer ring 501 is temporarily clamped and fixed by the two V-shaped clamps 305. When assembling the outer ring 501, inner ring 502, multiple tapered rollers 504 and spacer 505, the rotating column 405 is rotated to a vertical position. First, the outer ring 501 is temporarily fixed above the inner ring 502 by the two V-shaped clamps 305. After the inner ring 502, multiple tapered rollers 504 and spacer 505 are assembled, the horizontal column 301 is driven to slide down along the rotating column 405, and then the two V-shaped clamps 305 and two protrusions 306 press the outer ring 501 onto the multiple tapered rollers 504 on the inner ring 502. Rotating the threaded connection on the horizontal column 301 can fix the horizontal column 301 onto the rotating column 405, making it convenient to temporarily fix the two V-shaped clamps 305 and the outer ring 501 above the inner ring 502.

[0033] Both ends of the horizontal column 301 are fixed with stop pins 302. The two stop pins 302 are respectively blocked on the inner side of the two L-shaped frames 304. Both ends of the horizontal column 301 are fixed with spring seats 303. Each spring seat 303 is fixed with a compression spring. The other end of the compression spring is fixed on the corresponding L-shaped frame 304. The horizontal column 301 is located between the support bar 104 and the translation column 203. like Figure 4-7 As shown; The compression spring on the crossbar 301 provides a continuous opposing elastic force to the L-shaped frame 304, so that the two V-shaped clamps 305 can elastically clamp the outer ring 501, which not only ensures clamping stability, but also avoids excessive clamping force from damaging the surface of the outer ring 501; the stop pin 302 strictly limits the maximum sliding stroke of the L-shaped frame 304 to prevent the V-shaped clamps 305 from getting too close and causing structural interference, and ensures that the outer ring 501 is fastened and subsequent assembly processes are carried out in an orderly manner.

[0034] A tapered roller bearing processing apparatus, used for processing tapered roller bearings, includes the following steps: S1: Place the support ring 201 in a horizontal position and place the inner ring 502 on the multiple protrusions 202; S2: Place the isolation frame 505 onto the inner ring 502, at which point the support ring 201 supports the isolation frame 505; S3: Place multiple tapered rollers 504 into multiple through holes on the spacer 505, and insert multiple tapered rollers 504 into the tapered raceway 503; S4: Attach the outer ring 501 to the outside of the multiple tapered rollers 504; S5: Connect the anti-detachment ring 506 to one side of the outer ring 501 with screws, and install the annular cover 508 on the anti-detachment ring 506.

[0035] The orderly assembly of each component is achieved through a step-by-step process of "placing the inner ring horizontally → installing the isolation frame → placing the tapered roller → fastening the outer ring → installing the anti-detachment component".
