Description

Technical Field

[0001] This utility model belongs to the field of bearing processing technology, and more specifically, it relates to a self-aligning torque testing device for mounted spherical bearings. Background Technology

[0002] Mounted spherical roller bearings are used in the connection of mechanical equipment. During the production of mounted spherical roller bearings, the bearings are manufactured first, and then the bearings are installed in the bearing housing. During the production of the bearings, a self-aligning torque test is required. The self-aligning torque test requires a testing device. The staff installs the bearing inside the testing device, and the testing device tests and adjusts the bearing.

[0003] According to CN202320180806.8, this utility model relates to a self-aligning torque measuring device for a ball-mounted self-aligning bearing. This utility model includes a drive assembly comprising an output shaft, a torque sensor, a coupling, and a drive rod connected in sequence; a bearing assembly comprising a bearing housing connected to the drive rod, the bearing housing supporting the outer ring of the ball-mounted self-aligning bearing to be tested; and a loading assembly comprising a test mandrel, a locking element, a connecting rod, a load block connected to the connecting rod, and the drive assembly. The drive assembly drives the load block to move, allowing the test mandrel to pass through the ball-mounted self-aligning bearing to be tested and extend to the outside of the bearing housing, thus supporting the inner ring of the ball-mounted self-aligning bearing. The locking element locks the inner ring of the ball-mounted self-aligning bearing to the test mandrel. This utility model can simultaneously apply an axial load to the ball-mounted self-aligning bearing and detect the oscillation torque; it has a simple structure and is easy to operate.

[0004] Based on the above, existing testing devices generally place the bearing in a groove structure. After the bearing is placed inside the groove, bolts are used to install the bearing on the device for testing. After the bearing test is completed, the staff needs to remove the bolts and then take the bearing out of the groove, which is a rather cumbersome operation. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a self-aligning torque testing device for mounted spherical bearings. This solves the problem that existing testing devices generally place the bearing in a groove structure, and after the bearing is placed in the groove, bolts are used to install the bearing on the device for testing. After the bearing test is completed, the operator needs to remove the bolts and then take the bearing out of the groove, which is a cumbersome operation.

[0006] The purpose and effectiveness of this utility model's self-aligning torque testing device for mounted spherical bearings are achieved through the following specific technical means:

[0007] A self-aligning torque testing device for mounted spherical roller bearings includes a test base, a test mandrel, a support bracket, a placement base, a bearing groove, a test bearing, an installation limiting mechanism, and a bearing removal mechanism. The test mandrel is slidably connected to the left side of the upper end face of the test base. Multiple sets of support brackets are fixedly connected to the right side of the upper end face of the test base. The placement base is slidably connected to the left end face of the left support bracket, and the test mandrel slides on the inner end face of the placement base. The bearing groove is located in the middle of the upper end face of the placement base. The test bearing is placed inside the bearing groove. The installation limiting mechanism is located inside the test mandrel. The bearing removal mechanism is located inside the placement base.

[0008] Furthermore, the installation limiting mechanism includes: a power connecting rod, a power lever, and a test coupling; the power connecting rod is rotatably connected to multiple sets of support brackets, and the right end face of the base and the left end face of the power connecting rod are fixedly connected; the power lever is coaxially fixedly connected to the right end face of the power connecting rod; the test coupling is coaxially fixedly connected to the left side of the power connecting rod.

[0009] Furthermore, the installation limiting mechanism also includes: positioning slots and positioning blocks; there are two sets of positioning slots, which are respectively opened on the inner end face of the inner ring of the test bearing; there are two sets of positioning blocks, which are respectively slidably connected to the left and right sides inside the test mandrel, and the two sets of positioning blocks are respectively on the left and right end faces of the test mandrel, and the two sets of positioning blocks are respectively inserted into the two sets of positioning slots.

[0010] Furthermore, the installation limiting mechanism also includes: positioning connecting blocks and positioning springs; there are two sets of positioning connecting blocks, which are fixedly connected to the inner end faces of the two sets of positioning inserts, and the two sets of positioning connecting blocks slide inside the test mandrel; there are two sets of positioning springs, which are fixedly connected to the inside of the test mandrel, and the two sets of positioning springs are elastically connected to the inner end faces of the two sets of positioning connecting blocks.

[0011] Furthermore, the installation limiting mechanism also includes: a stabilizing connecting rod and a stabilizing torsion block; the stabilizing connecting rod is rotatably connected to the upper side inside the test mandrel; the stabilizing torsion block is coaxially fixedly connected to the middle position of the upper end face of the stabilizing connecting rod.

[0012] Furthermore, the installation limiting mechanism also includes: a positioning limiting block and a stabilizing block; there are two sets of positioning limiting blocks, and the two sets of positioning limiting blocks are respectively fixedly connected to the inner end faces of the two sets of positioning connecting blocks; the stabilizing block is coaxially fixedly connected to the middle position of the lower end face of the stabilizing connecting rod, and the stabilizing block rotates on the inner end faces of the two sets of positioning limiting blocks.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This invention employs an installation limiting mechanism. When the test bearing is placed inside the bearing groove, the test bearing moves the positioning slot to the positioning block. The positioning spring then causes the positioning block to slide into the positioning slot. The operator then twists the stabilizing block, which in turn rotates the stabilizing stop. The rotation of the stabilizing stop prevents the positioning block from sliding out of the positioning slot, ensuring that the test bearing is securely installed inside the bearing groove. This eliminates the need for the operator to use bolts to fix the test bearing to the test spindle, making it easier for the operator to install the test bearing on the device.

[0016] This utility model employs a bearing-handling mechanism, which allows staff to easily remove the bearing from its groove when needed. The staff simply twists the stabilizing block, and the spring force causes the handle slider to slide, which in turn causes the bearing to slide out of the groove, making it easy for staff to retrieve the bearing.

[0025] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0026] Example 1: As shown in the attached document Figure 1 To be continued Figure 5 As shown:

[0027] This utility model provides a self-aligning torque testing device for a mounted spherical bearing, including a test base 1, a test spindle 2, a support bracket 3, a placement base 4, a bearing groove 401, a test bearing 6, and an installation limiting mechanism. The test spindle 2 is slidably connected to the left side of the upper end face of the test base 1, and slides on the left side of the upper end face of the test base 1. Multiple sets of support brackets 3 are provided, and the multiple sets of support brackets 3 are respectively fixedly connected to the right side of the upper end face of the test base 1. The placement base 4 is slidably connected to the left end face of the left support bracket 3, and the test spindle 2 slides on the inner end face of the placement base 4. The bearing groove 401 is opened in the middle of the upper end face of the placement base 4. The test bearing 6 is placed inside the bearing groove 401. The installation limiting mechanism is set inside the test spindle 2.

[0028] The installation limiting mechanism includes: a power connecting rod 5, a power lever 501, and a test coupling 502. The power connecting rod 5 is rotatably connected to multiple sets of support brackets 3, and the right end face of the base 4 and the left end face of the power connecting rod 5 are fixedly connected. The power lever 501 is coaxially fixedly connected to the right end face of the power connecting rod 5. The test coupling 502 is coaxially fixedly connected to the left side of the power connecting rod 5. During use, the operator turns the power lever 501 to rotate, which drives the power connecting rod 5 to rotate. The rotation of the power connecting rod 5 drives the test coupling 502 to rotate. The rotation of the test coupling 502 drives the power connecting rod 5 to rotate. The rotation of the power connecting rod 5 drives the base 4 to swing. The swing of the base 4 drives the test bearing 6 to swing, and the test bearing 6 is adjusted for self-alignment.

[0029] The installation limiting mechanism also includes: positioning slots 601 and positioning blocks 7; there are two sets of positioning slots 601, which are respectively opened on the inner end face of the inner ring of the test bearing 6; there are two sets of positioning blocks 7, which are respectively slidably connected to the left and right sides inside the test spindle 2, and the two sets of positioning blocks 7 are respectively on the left and right end faces of the test spindle 2. The two sets of positioning blocks 7 are respectively inserted into the two sets of positioning slots 601. During use, the positioning blocks 7 slide on the outer end face of the test spindle 2, and the test bearing 6 is placed inside the bearing groove 401 of the placement base 4. The movement of the test bearing 6 drives the positioning slots 601 to move, and the movement of the positioning slots 601 drives the positioning blocks 7 to slide into the test spindle 2. When the positioning slots 601 move to the position of the positioning blocks 7.

[0030] The installation limiting mechanism also includes: positioning connecting blocks 8 and positioning springs 801; there are two sets of positioning connecting blocks 8, which are fixedly connected to the inner end faces of the two sets of positioning inserts 7 respectively, and the two sets of positioning connecting blocks 8 slide inside the test spindle 2 respectively; there are two sets of positioning springs 801, which are fixedly connected to the inside of the test spindle 2 respectively, and the two sets of positioning springs 801 are elastically connected to the inner end faces of the two sets of positioning connecting blocks 8 respectively. During use, the sliding of the positioning inserts 7 causes the positioning connecting blocks 8 to slide, and the sliding of the positioning connecting blocks 8 causes the positioning springs 801 to extend and retract. The elastic force of the positioning springs 801 causes the positioning inserts 7 to slide into the positioning slots 601.

[0031] The installation limiting mechanism also includes: a stabilizing connecting rod 9 and a stabilizing torsion block 901; the stabilizing connecting rod 9 is rotatably connected to the upper side inside the test spindle 2; the stabilizing torsion block 901 is coaxially fixedly connected to the middle position of the upper end face of the stabilizing connecting rod 9. During use, the operator twists the stabilizing torsion block 901 to rotate, thereby causing the stabilizing connecting rod 9 to rotate.

[0032] The installation limiting mechanism also includes: a positioning limiting block 802 and a stabilizing block 902; there are two sets of positioning limiting blocks 802, which are fixedly connected to the inner end faces of the two sets of positioning connecting blocks 8 respectively; the stabilizing block 902 is coaxially fixedly connected to the middle position of the lower end face of the stabilizing connecting rod 9. The stabilizing block 902 rotates within the inner end faces of the two sets of positioning limiting blocks 802. During use, the rotation of the stabilizing connecting rod 9 drives the stabilizing block 902 to rotate. When the stabilizing block 902 rotates to the horizontal position, it blocks the sliding of the positioning limiting block 802, so that the positioning insert 7 slides into the positioning slot 601 and cannot be separated. When the stabilizing block 902 rotates to the vertical position, the positioning insert 7 can be separated from the positioning slot 601, making it easy to remove the test bearing 6 from the bearing groove 401.

[0033] The specific usage and function of this first embodiment are as follows:

[0034] During use, the operator rotates the power lever 501, which in turn rotates the power connecting rod 5. The rotation of the power connecting rod 5 then rotates the test coupling 502, which in turn rotates the power connecting rod 5. This rotation of the power connecting rod 5 causes the placement base 4 to swing, which in turn causes the test bearing 6 to swing. Adjusting the test bearing 6 involves self-aligning the positioning block 7, which slides on the outer end face of the test spindle 2. The test bearing 6 is placed inside the bearing groove 401 of the placement base 4. The movement of the test bearing 6 causes the positioning slot 601 to move, which in turn causes the positioning block 7 to slide into the test spindle 2. When the positioning slot 601 reaches the position of the positioning block 7, the sliding of the positioning block 7 causes the positioning... The positioning connecting block 8 slides, which causes the positioning spring 801 to extend and retract. The elastic force of the positioning spring 801 causes the positioning insert 7 to slide into the positioning slot 601. The operator twists the stabilizing toggle block 901 to rotate, which causes the stabilizing connecting rod 9 to rotate. The stabilizing connecting rod 9 rotates, which causes the stabilizing stop block 902 to rotate. When the stabilizing stop block 902 rotates to the horizontal position, it blocks the positioning limiting block 802 from sliding, so that the positioning insert 7 cannot be separated from the positioning slot 601. When the stabilizing stop block 902 rotates to the vertical position, the positioning insert 7 can be separated from the positioning slot 601, making it easy to remove the test bearing 6 from the bearing groove 401 and install the test bearing 6 on the test device.

[0035] Example 2: Based on Example 1, as shown in the appendix Figure 6 As shown:

[0036] This utility model provides a self-aligning torque testing device for a mounted spherical bearing, and also includes a bearing handling mechanism disposed inside a base 4. The bearing handling mechanism includes a handling slider 10 and a handling spring 1001. The handling slider 10 is slidably connected to the lower side inside the base 4, slides inside the bearing groove 401, and slides under the test bearing 6. Multiple sets of handling springs 1001 are provided, and the multiple sets of handling springs 1001 are respectively fixedly connected inside the base 4. The lower end face of the 0 is elastically connected to the lower end face of multiple sets of portable springs 1001. During use, when the test bearing 6 is placed inside the bearing groove 401, the movement of the test bearing 6 causes the portable slider 10 to slide. The sliding of the portable slider 10 causes the portable springs 1001 to extend and retract. The elastic force of the portable springs 1001 causes the portable slider 10 to slide upward. The upward sliding of the portable slider 10 causes the test bearing 6 to slide upward, making it convenient for the test bearing 6 to slide upward to the upper side inside the bearing groove 401, making it easy for the staff to pick up the test bearing 6 inside the bearing groove 401.

[0037] The specific usage and function of this second embodiment are as follows:

[0038] During use, when the test bearing 6 is placed inside the bearing groove 401, the movement of the test bearing 6 causes the portable slider 10 to slide. The sliding of the portable slider 10 causes the portable spring 1001 to extend and retract. The elastic force of the portable spring 1001 causes the portable slider 10 to slide upward, which in turn causes the test bearing 6 to slide upward, making it easier for the test bearing 6 to slide upward to the upper side of the bearing groove 401, thus making it easier for staff to pick up the test bearing 6 inside the bearing groove 401.
