Description

Technical Field

[0001] The invention relates to the technical field of insulating bearing testing, and in particular to a dynamic balancing testing device for an outer ring of an insulating bearing. Background Art

[0002] An insulated bearing is a specially designed bearing whose internal components are wrapped or treated with insulating materials to prevent current from flowing inside the bearing. This design is common in application scenarios where it is necessary to prevent current from being conducted through the bearing, such as in motor or generator systems. The main function of an insulated bearing is to isolate the metal components inside the bearing, prevent current from flowing through the bearing, and ensure the normal operation and safety of the equipment. During the production stage of insulated bearings, an outer ring dynamic balancing test is usually part of ensuring the quality of the bearing. By performing a dynamic balancing test on the outer ring of the insulated bearing to ensure that it meets the specified balancing requirements when leaving the factory, this helps to reduce manufacturing defects and ensure that the bearing meets standard performance before being put into use, avoiding unbalanced outer rings of insulated bearings that increase additional friction and wear. If the insulating paint on the outer ring of the insulated bearing is worn or damaged, its insulation performance may be affected, thereby increasing the risk of current flowing inside the bearing.

[0003] However, there are some problems in the actual working process of the existing bearing outer ring dynamic balancing test device. For example, a bearing dynamic balancing test auxiliary device with publication number CN116380342B can test the dynamic balance of the bearing outer ring during operation, but it can only test the dynamic balance of the insulating bearing outer ring in the horizontal direction, and cannot test the dynamic balance of the insulating bearing outer ring in the horizontal direction and the dynamic balance in the vertical direction at the same time, so it is not practical. In addition, it uses a marker pen and a sticker for testing, which will cause unnecessary resource consumption. Moreover, in the actual working process, it cannot automatically and efficiently clean the inner and outer rings of the insulating bearing in advance. Therefore, dust, impurities and oil stains on the inner and outer rings of the insulating bearing can easily lead to unstable subsequent fixation, and easily lead to deviations in subsequent test results. It is not practical. Therefore, it is necessary to provide an insulating bearing outer ring dynamic balancing test device to meet the needs of users. Summary of the invention

Therefore, after the insulating bearing is cleaned and degreased, it falls onto the second telescopic sleeve. The cooperation of the electric heating tube and the exhaust fan can efficiently dry the insulating bearing. Similarly, the insulating bearing continues to be unloaded after drying and can stably fall onto the fixed frame, ensuring the convenience and efficiency of its subsequent positioning and detection work. By repeatedly pressing the first positioning block, the cleaning, degreasing, drying and automatic loading of the inner and outer rings of the insulating bearing can be efficiently completed, thereby ensuring the accuracy and convenience of the subsequent testing of the insulating bearing.

When the insulating bearing is dynamically balanced, the outer ring of the insulating bearing can be driven to rotate stably by the rubber wheel. If the outer ring of the insulating bearing is unbalanced, the mass distribution of the outer ring of the bearing will be uneven, and the rotation of the outer ring of the bearing will deviate from the axis, thereby pushing the contact plate fitted to the side end face of the outer ring of the bearing and the measuring plate fitted to the upper and lower end faces of the outer ring of the bearing to automatically move.

It has a simple structure, low cost, and is easy to promote and use. Moreover, through the cooperation of the dynamic balancing detector and the photoelectric sensor, unqualified insulating bearings can be further accurately tested, thereby improving the testing efficiency of the bearings.

When the insulating bearing is dynamically balanced, the outer ring of the insulating bearing can be driven to rotate stably by the rubber wheel 21.

The first clamping rod 2208 and the first measuring groove 2205 can automatically engage the displaced contact plate 2203, thereby ensuring the convenience and accuracy of subsequent detection work.

[0055] In this embodiment, a second measuring groove 2209 is provided on the inner wall of the transparent mounting frame 2201, a measuring plate 2210 is slidably connected in a limited position in the transparent mounting frame 2201, a second connecting spring 2211 is fixedly connected in the measuring plate 2210, a second clamping rod 2212 is fixedly connected at the other end of the second connecting spring 2211, the second clamping rod 2212 is slidably connected in the measuring plate 2210, a traction rope 2213 is fixedly connected at the end of the second clamping rod 2212, the traction rope 2213 is slidably connected in the measuring plate 2210, a connecting ring 2214 is fixedly connected at the end of the traction rope 2213, the measuring plates 2210 are symmetrically distributed on the upper and lower sides of the measuring rod 2204, the second clamping rod 2212 is symmetrically distributed on both sides of the measuring plate 2210, the second measuring grooves 2209 are equidistantly distributed on both sides of the measuring plate 2210, a scale is provided on the transparent mounting frame 2201, and the second measuring grooves 2209 and the transparent mounting frame 2201 are symmetrically distributed on the upper and lower sides of the measuring rod 2204, the second clamping rod 2212 is symmetrically distributed on both sides of the measuring plate 2210, The second threaded rod 18 corresponds to the scale on the mounting frame 19, the bottom end surface of the mounting frame 19 is fitted with the top surface of the workbench 1, the horizontal center line of the rubber wheel 21 is on the same horizontal line as the horizontal center line of the contact plate 2203, and the center point between the two positioning plates 15 at the top of the guide rod 14 close to the rubber wheel 21 is on the horizontal center line of the rubber wheel 21. The second clamping rod 2212 and the second measuring groove 2209 can be used to automatically clamp the displaced measuring plate 2210. The staff only needs to observe the displacement of the first clamping rod 2208 and the second clamping rod 2212 before and after the test to simultaneously test the horizontal dynamic balance and vertical dynamic balance of the outer ring of the insulating bearing. At the same time, by observing and comparing the displacement of the first clamping rod 2208 and the second clamping rod 2212 before and after the test, the test result of the dynamic balance of the outer ring of the insulating bearing can be conveniently and accurately obtained.

[0056] It should be noted that the present invention is a dynamic balancing test device for the outer ring of an insulating bearing. First, the staff can rotate the first threaded rod 7 in the workbench 1. The rotation of the first threaded rod 7 can drive the threaded fixed frame 8 to move to the outermost side. At this time, the fixed frame 8 is located directly below the processing frame 319. Then, the staff can rotate the worm 9 in the fixed frame 8. At this time, the meshing drive of the worm 9 and the worm wheel 10 can be used to drive the turntable 12 to rotate through the connecting shaft 11 on the worm wheel 10. At this time, under the rotation of the turntable 12, the four first guide grooves 13 can be driven to perform synchronous circular motion, and under the circular motion of the first guide groove 13, the guide rod 14 can be moved. At this time, under the limiting guiding action of the second guide groove 17 on the fixed plate 16, the first guide groove 13 can move the guide rod 14 along the second guide groove 17. At this time, each guide rod 14 can move outward or inward at the same time. By moving each guide rod 14 inward at the same time, the bottom of the processing frame 319 can be conveniently and stably clamped and fixed;

[0057] Then the staff can drive the hydraulic rod 2, and use the hydraulic rod 2 to drive the liquid storage tank 301 to move upward. At this time, the liquid storage tank 301 can drive the first connecting plate 307 at the bottom to move synchronously, so that the second positioning groove 314 at the bottom of the support rod 313 can move away from the second positioning block 315. Similarly, the first positioning groove 310 at the bottom of the second connecting plate 309 can move away from the first positioning block 316. Then the staff can put the insulating bearing to be tested on the processing frame 319. At this time, the insulating bearing can be stably placed on each first telescopic sleeve frame 328. After being stably placed , the staff can drive the hydraulic rod 2 again, and use the hydraulic rod 2 to drive the liquid storage tank 301 to move downward and reset. At this time, the second positioning groove 314 at the bottom of the support rod 313 can be engaged with the second positioning block 315. Similarly, the first positioning groove 310 at the bottom of the second connecting plate 309 can be engaged with the first positioning block 316. Then the staff can drive the first motor 332 on the fixing frame 331. At this time, the first motor 332 can drive the driving shaft 318 to rotate stably, and then the support rod 313 can be rotated through the second positioning block 315 at the top, thereby driving the liquid storage tank 301 rotates, and under the action of the rotation of the liquid storage tank 301, the first connecting plate 307 can be driven to rotate on the second connecting plate 309, and can drive each conveying cylinder 303 at the bottom of the liquid storage tank 301 to perform a circular motion. During the circular motion of each conveying cylinder 303, the spiral rod 304 inside it can be driven to perform a synchronous motion. At this time, the second bevel gear 312 on the spiral rod 304 performs a circular motion on the first bevel gear 311. By utilizing the meshing of the first bevel gear 311 and the second bevel gear 312, the spiral rod 304 can be driven to perform a circular motion. The delivery tube 303 rotates automatically inside, and the cleaning liquid in the liquid storage tank 301 can be uniformly transported to the second liquid guide tube 305 through the first liquid guide tube 302, and the cleaning liquid can be uniformly sprayed on the inner and outer rings of the bearing by using each atomizing nozzle 306. At the same time, through the rotation of the first connecting plate 307, each flexible brush 308 can simultaneously automatically clean the inner and outer rings of the insulating bearing, thereby conveniently and efficiently removing dust and oil stains on the inner and outer rings of the insulating bearing, which helps to prevent these impurities from affecting the test results and ensure the accuracy of the test;

[0058] After the cleaning work is completed, the hydraulic rod 2 is used to drive the liquid storage tank 301 to move upward again, and then the staff can press the first positioning block 316 downward. Under the movement of the first positioning block 316, the fixing plate 322 can be driven downward by the active shaft 318, and under the guiding action of the inclined surface at the end of the push rod 324 and the inclined surface at the end of the sliding rod 321, the push rod 324 can automatically move into the fixing plate 322 until the fixing plate 322 drives the push rod 324 to move below the sliding rod 321, and then the staff can release the first positioning block 316. At this time, under the elastic action of the strong spring 317, the active shaft 318 can be driven to move upward automatically through the first positioning block 316, and then the fixing plate 322 can be driven upward. At this time, the push rod 324 can move the sliding rod 321 upward until it is in contact with the push rod 324. 24, the end inclined surface of the sliding rod 321 is used again to push the push rod 324 to move into the fixing plate 322 until the fixing plate 322 drives the push rod 324 to move above the fixing rod 320, and then the fixing plate 322 continues to move upward to the top of the processing frame 319. Under the movement of the fixing plate 322, the first piston 326 can be driven upward by the first plug rod 325, and the first rubber airbag 329 in the first telescopic sleeve 328 can be automatically evacuated through the first air guide pipe 330 at the bottom of the first air storage cylinder 327. At this time, the first rubber airbag 329 shrinks and recovers to its original state by its own elasticity. Therefore, the first telescopic sleeve 328 can shrink automatically, and the first telescopic sleeve 328 is completely shrunk into the processing frame 319. At this time, the bottom support of the insulating bearing disappears, and the insulating bearing automatically falls.

[0059] When the fixing plate 322 moves upward, the driving shaft 318 also drives the connecting mesh frame 340 to move upward on the limiting rod 339, and the fixing frame 331 also moves upward. Similarly, at this time, the fixing frame 331 can drive the second piston 334 to move upward through the second plug rod 333, and the second rubber airbag 337 can be automatically inflated through the second air guide pipe 338 on the top of the second air storage cylinder 335. The second rubber airbag 337 can be automatically extended by the expansion of the second rubber airbag 337. At this time, the falling bearing can automatically fall on each second telescopic sleeve 336. At this time, the first motor 332 is still used to drive the driving shaft 318 to rotate. Under the rotation of the driving shaft 318, the third bevel gear 342 can drive the driven shafts 344 on each fourth bevel gear 343 to rotate at the same time, and then the exhaust fans 345 on each driven shaft 344 can be driven to rotate, and the insulated bearings can be efficiently dried in cooperation with the electric heating tube 341 and the fixed mesh plate 346.

[0060] During the bearing treatment process, excess cleaning liquid can automatically fall onto the rubber plate 5, and under the guidance of the rubber plate 5, can be discharged through the drain pipe 6, and then the rubber plate 5 can be dried by the high-temperature air during the insulating bearing drying process. After the insulating bearing is dried, the first positioning block 316 can be pressed downward again. Under the movement of the first positioning block 316, the fixing plate 322 can be driven downward by the active shaft 318. Similarly, under the guidance of the inclined surface at the end of the fixing rod 320, the push rod 324 can be automatically pushed into the fixing plate 322 until the fixing plate 322 drives the push rod 324 to move below the fixing rod 320, and then the staff can loosen the fixing plate 322. Open the first positioning block 316. At this time, under the snapping action of the top of the fixing rod 320, the fixing plate 322 can be automatically snapped through the top rod 324. At this time, the fixing plate 322 returns to its original position. In combination with the above, it can be seen that the first telescopic sleeve 328 automatically extends outward, and the second telescopic sleeve 336 automatically contracts, completing the reset of the first telescopic sleeve 328 and the second telescopic sleeve 336. At this time, under the automatic contraction of the second telescopic sleeve 336, the insulating bearing loses support and automatically falls. At this time, the insulating bearing can move the rubber plate 5. At this time, the rubber plate 5 will not block the insulating bearing. The insulating bearing can automatically fall onto the fixing frame 8 under the action of its own gravity to complete the automatic feeding work;

[0061] Then the staff can rotate the worm 9 in the opposite direction, and then each guide rod 14 moves to the side at the same time. At this time, under the movement of each guide rod 14, the inner ring of the insulating bearing can be supported and fixed by using the inclined surface of the positioning plate 15, and the insulating bearing can be automatically positioned so that its horizontal center line is on the same horizontal line as the horizontal center line of the rubber wheel 21. When each guide rod 14 moves to the side at the same time, each guide rod 14 will be separated from the processing frame 319. At this time, the staff only needs to manually lift the processing frame 319 and rotate the first threaded rod 7 at the same time. The rotation of the first threaded rod 7 drives the fixed frame 8 to move toward the transparent installation frame 2201. Then the staff can release the processing frame 319, and the processing frame 319 will not affect the subsequent testing work.

[0062] When starting the test, the staff can rotate the second threaded rod 18 on the fixed frame 8, and use the thread rotation of the second threaded rod 18 to drive the rubber wheel 21 on the second motor 20 to squeeze and contact the bearing through the mounting frame 19, and use the rotation of the first threaded rod 7 to drive the insulating bearing to squeeze and fit the contact plate 2203 through the fixed frame 8. Before the insulating bearing and the contact plate 2203 fit, the staff can pull the traction rope 2213 on the connecting ring 2214 to use the traction rope 2213 to drive the second clamping rod 2212 to move out of the second measuring groove 2209, and at this time the upper measuring plate 2210 can move After the insulating bearing and the contact plate 2203 are pressed and fitted, the staff can pull the traction rope 2213 on the connecting ring 2214 again, and at this time, move the upper measuring plate 2210 downward, and move the lower measuring plate 2210 upward, until the measuring plates 2210 on the upper and lower sides are respectively fitted with the upper and lower end surfaces of the outer ring of the insulating bearing, and then the staff can loosen the traction rope 2213 on the connecting ring 2214. At this time, under the elastic action of the second connecting spring 2211, the second clamping rod 2212 can be driven to automatically engage in the second measuring groove 2209;

[0063] Then, the second motor 20 is used to drive the rubber wheel 21 to rotate, and the friction force can drive the outer ring of the insulating bearing to rotate. At this time, during the rotation of the outer ring of the insulating bearing, if the outer ring of the insulating bearing is unbalanced, it will cause the mass distribution of the outer ring of the bearing to be uneven, and the rotation of the outer ring of the bearing will deviate from the axis. At this time, the rotation trajectory of the outer ring of the bearing is irregular, which will cause the outer ring of the bearing to present an elliptical rotation trajectory in space. Therefore, under the rotation of the outer ring of the bearing, the contact plate 2203 that is in contact with the side end face of the outer ring of the bearing can be pushed to automatically move. Under the movement of the contact plate 2203, the measuring rod 2204 can be driven to automatically move into the transparent sleeve 2206. During the movement of the measuring rod 2204, the end inclined surface of the first clamping rod 2208 and the internal inclined surface of the first measuring groove 2205 can be used to push the first clamping rod 2208 on the transparent sleeve 2206 to automatically move outward and disengage from the first measuring groove 2205. The first connecting spring 2207 can drive the first clamping rod 2208 to automatically engage with the next first measuring groove 2205 to avoid the contact plate 2203 and the measuring rod 2204 from resetting. Similarly, under the rotation of the outer ring of the bearing, the measuring plate 2210 that fits the upper and lower end surfaces of the outer ring of the bearing can be pushed to automatically move. The first clamping rod 2208 and the first measuring groove 2205 can also automatically engage the displaced contact plate 2203 to avoid its movement resetting. The staff only needs to observe the displacement of the first clamping rod 2208 and the second clamping rod 2212 before and after the test to simultaneously test the horizontal dynamic balance and the vertical dynamic balance of the outer ring of the insulating bearing. By observing and comparing the displacement of the first clamping rod 2208 and the second clamping rod 2212 before and after the test, the test result of the dynamic balance of the outer ring of the insulating bearing can be obtained conveniently and accurately, and the staff can avoid detection errors by repeating the test multiple times.

[0064] When the test result is unqualified, the staff can reversely rotate the first threaded rod 7, and use the reverse rotation of the first threaded rod 7 to drive the insulating shaft to move away from the contact plate 2203 through the fixed frame 8, and then start the balance detector 2216 model VT700 and the photoelectric sensor 2215. The photoelectric sensor 2215 detects the movement of the outer ring of the insulating bearing through the principle of photoelectric effect. When light is irradiated to the surface of the outer ring of the insulating bearing, it will produce a certain degree of scattering or reflection of the light. This change in light can be captured and detected by the photoelectric sensor. When the outer ring rotates, the slight imbalance or deviation on its surface will cause changes in the reflection or scattering of light. These changes are detected by the photoelectric sensor and converted into electrical signals. By analyzing the changes in these electrical signals, the rotation speed, angle and degree of imbalance of the outer ring can be determined. If there is a dynamic balance problem with the outer ring, such as unbalanced mass distribution or axial offset, then during the rotation process, the photoelectric sensor 2215 will detect the light reflection or The scattering changes will display irregular signal patterns on the dynamic balancing detector 2216. According to these signal patterns, the dynamic balancing state of the outer ring can be evaluated. Since the operation required for the precise dynamic balancing test is relatively cumbersome, and in combination with the above, it can be seen that the present application does not need to perform precise dynamic balancing tests on each insulating bearing, but only needs to perform dynamic balancing tests on unqualified insulating bearings, thereby effectively improving the testing efficiency. When the test is completed, the staff can pull the traction rope 2213 on the connecting ring 2214 again, and use the traction rope 2213 to drive the second clamping rod 2212 to move out of the second measuring slot 2209. At this time, the measuring plate 2210 can be moved and reset, and the staff can pull the first clamping rod 2208 on the transparent sleeve 2206 outward to make it move out of the first measuring slot 2205 on the measuring rod 2204. Then the measuring rod 2204 and the contact plate 2203 can be moved and reset, ensuring the stability and convenience of subsequent repeated working states.

[0065] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
