Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bearing group torque measurement, in particular to a torque measuring device for fully lubricating a bearing group. Background Art
[0002] Bearings are important components in mechanical manufacturing. They support mechanical rotating bodies and reduce the friction coefficient during their movement, thereby ensuring their rotation accuracy. Therefore, bearing torque measurement is particularly critical. By measuring bearing torque, equipment utilization can be improved and maintenance costs can be reduced. When a fault occurs, combined with vibration, noise, and oil monitoring technologies, the specific location of the fault, the severity of the fault, and the cause of the fault can be further diagnosed, thereby reducing downtime and improving economic benefits.
[0003] The existing bearing group torque measurement method generally uses the torque tester's motor to drive the bearing to rotate, thereby monitoring the bearing's torque measurement data. However, when the bearing group is subjected to torque testing, it is easy for the internal grease of the tested bearing group to be insufficient or aged, resulting in errors in the test data. The general tester fixing device is a sealed test to prevent debris from adhering to the bearing group during the test. When insufficient lubrication occurs, the sealing device needs to be disassembled before continuing the monitoring operation, and the measurement efficiency is generally average.

The surface of the bottom end is fixedly connected with the inner ring upper pressure plate 11, and the bearing body 16 and the inner ring lower pressure plate 18 are arranged below the connecting column 4. The center of the bottom of the inner ring lower pressure plate 18 is fixedly connected with a connecting screw 17, and the top of the connecting screw 17 is threadedly connected to the bottom of the connecting column 4. The outer ring upper pressure plate 13 is arranged above the outer ring fixed bottom block 21. The top of the outer ring upper pressure plate 13 and the outer ring fixed bottom block 21 are both provided with threaded holes, and the inner wall of the threaded hole is threadedly connected with a fixing screw 12, which can better fix the bearing body 16.
[0023] Furthermore, the lubrication mechanism includes an oil storage barrel 6 and an oil pump 7. A pipe plug 5 is movably inserted at the top of the oil storage barrel 6. One end of the oil pump 7 is fixedly connected to one side of the oil storage barrel 6. The end of the oil pump 7 away from the oil storage barrel 6 is fixedly connected to an oil pipe 8. The end of the oil pipe 8 away from the oil pump 7 is fixedly connected to the top of the outer ring upper pressure plate 13. The end of the oil pipe 8 away from the oil pump 7 is located above the ball of the bearing body 16. The side of the oil storage barrel 6 away from the oil pump 7 is fixedly connected to a scale observation window 25. By adding grease to the bearing body 16 in real time, the impact of insufficient lubrication on the torque measurement data of the bearing group is reduced.
[0024] Furthermore, the bottom of the inner ring upper pressure plate 11 and the top of the inner ring lower pressure plate 18 are fixedly connected with the inner ring anti-slip pad 15, and the bottom side and top side of the two inner ring anti-slip pads 15 are movably fitted to the top and bottom of the inner ring of the bearing body 16 respectively. The bottom of the outer ring upper pressure plate 13 and the bottom of the inner side of the outer ring fixed bottom block 21 are fixedly connected with the outer ring anti-slip pad 20, and the bottom side and top side of the two outer ring anti-slip pads 20 are movably fitted to the top and bottom of the outer ring of the bearing body 16 respectively, which can greatly increase the stability of the bearing body 16 when it is fixed.
[0025] Furthermore, the top of the torque detector 10 is fixedly connected to a fixing rod 9, and the top of the fixing rod 9 is fixedly connected to a support ring 19 to prevent the oil pipeline 8 from being accidentally drawn into the connecting column 4 due to external force when the bearing body 16 is being tested.

[0028] Furthermore, a plug-in slot is provided on the top of the torque tester 10, and an oil absorption block 22 is movably inserted into the inner wall of the plug-in slot. The oil absorption block 22 is located below the ball of the bearing body 16, and can absorb excess grease, reduce grease leakage, and improve the fixing effect of the bearing body 16.
[0029] Working principle: First, pass the connecting screw 17 in the middle of the inner ring lower pressure plate 18 through the inside of the bearing body 16. At this time, the inner ring anti-slip pad 15 on the top of the inner ring lower pressure plate 18 fits with the bottom of the inner ring of the bearing body 16. Then use the connecting screw 17 to make the inner ring upper pressure plate 11 and the inner ring lower pressure plate 18 tightly clamp the inner ring of the bearing body 16. At this time, the inner ring anti-slip pad 15 at the bottom of the inner ring upper pressure plate 11 fits tightly with the top of the inner ring of the bearing body 16. Then drive the motor 14 through the electric push rod 1 , the connecting column 4 and the bearing body 16 move downward. When the sliding groove at the bottom of the inner ring lower pressure plate 18 fits the surface of the limit slip ring 23, the electric push rod 1 stops operating. At this time, the top of the outer ring anti-slip pad 20 inside the outer ring fixed bottom block 21 fits the bottom of the outer ring of the bearing body 16. Then, the bottom of the outer ring anti-slip pad 20 of the outer ring upper pressure plate 13 fits the top of the outer ring of the bearing body 16, and the outer ring upper pressure plate 13 and the outer ring fixed bottom block 21 are fixed by the fixing screws 12. At this time, the outer ring of the bearing body 16 is clamped by the outer ring upper pressure plate 13 and the outer ring fixed bottom block 21, and then the pipe plug 5 is pulled out from the top of the oil storage barrel 6, and oil-based grease is injected into the oil storage barrel 6. After the injection, the pipe plug 5 is reinserted, and the bent section of the oil pipe 8 is placed in the support ring 19 at the top of the fixed rod 9 to prevent it from being accidentally drawn into the connecting column 4. At this time, the motor 14 and the oil pump 7 are started respectively. The motor 14 drives the inner ring of the bearing body 16 to rotate through the connecting column 4, the inner ring upper pressure plate 11 and the inner ring lower pressure plate 18, so that the torque detector 10 records the torque data of the bearing body 16, and the grease in the oil storage barrel 6 is injected into the ball of the bearing body 16 through the oil pump 7 and the oil pipe 8 for lubrication, thereby preventing the bearing body 16 from being insufficiently lubricated during the detection process and causing incorrect detection data. The oil absorption block 22 at the bottom of the bearing body 16 can absorb excess grease, reduce grease leakage, and improve the fixing effect of the bearing body 16.
