[0002] During the gearbox production process, the running-in test is a key step in ensuring its quality and performance. During the traditional gearbox running-in process, the internal gears and housing will generate some impurities during operation. If these impurities are not purified in time, these pollutants will aggravate the wear of the internal parts of the gearbox, affect the accuracy of the test results, reduce the service life of the oil, and increase the testing cost.

[0003] On the other hand, existing running-in workbenches often lack precise measurement and control systems, and are unable to monitor the vibration of the gearbox during the running-in process in real time and accurately, making it difficult to detect potential problems with the gearbox in a timely manner, which is not conducive to improving production efficiency and product quality.

[0019] Preferably, the oil circulation mechanism includes a filter element, and an oil inlet pipe and an oil outlet pipe are fixedly connected to both sides of the filter element. The oil inlet pipe and the oil outlet pipe both pass through the workbench and extend to its outside. The oil inlet pipe and the oil outlet pipe are connected to the oil pool of the gearbox. An oil pump is fixedly installed on the oil outlet pipe. The oil inlet pipe introduces the oil in the gearbox oil pool into the filter element, and the oil outlet pipe returns the filtered oil to the gearbox oil pool to realize oil circulation. The oil pump provides power for the oil circulation to ensure that the oil can be continuously extracted, filtered and returned.

[0020] The filter element preferably includes an oil reservoir, wherein the inner wall of the oil reservoir is fixedly installed with a baffle, the baffle dividing the oil reservoir interior into an oil inlet chamber and an oil outlet chamber, and a filter is fixedly installed between the top of the baffle and the inner wall of the oil reservoir, the filter screen is arranged in the oil outlet chamber of the oil reservoir, and a chip groove is formed at the bottom of the oil outlet chamber of the oil reservoir, the oil reservoir stores oil, the baffle separates the oil inlet chamber and the oil outlet chamber, the filter screen filters the oil and removes impurities, and the chip groove is convenient for collecting the filtered impurities, and the oil flows into the oil inlet chamber of the oil reservoir tank of the filter element through the oil inlet pipe under the action of pressure.

[0021] The present invention provides a gearbox running-in workbench with circulating oil purification and measurement and control functions. It has the following beneficial effects:

[0022] 1. This gearbox running-in workbench, which has the effects of circulating oil purification and measurement and control, uses a drive mechanism. The motor output end drives the transmission shaft to rotate, and the transmission shaft provides power input to the gearbox, simulating the power output of the engine under actual working conditions. This enables the gearbox to be run-in tested on the workbench.

[0023] 2. The gearbox running-in workbench with circulating oil purification and measurement and control effects, through the setting of the shaft connection mechanism, during the power transmission process, the annular sleeve of the sleeve shaft part 2 is inserted into the docking groove of the sleeve shaft part 1, the ball and the arc groove are snap-fitted and adapted, and the positioning spring facilitates the positioning of the ball and the arc groove. The shaft connection mechanism realizes a stable connection between the drive mechanism and the gearbox, ensures efficient and reliable power transmission, and ensures that the gearbox running-in test is carried out smoothly.

[0024] 3. This gearbox running-in workbench, which has the effects of circulating oil purification and measurement and control, has a fixed vibration measuring mechanism. The rotating plate on the docking plate rotates via a rotating shaft. There is an elastic steel sheet between the rotating plates. The card strips on the rotating plate surface are snap-fitted with the card slots on both sides of the inner wall of the card box. There is a buffer spring between the end of the rotating plate away from the docking plate and the inner wall of the card box. When the buffer member approaches the gearbox, the buffer spring and the elastic steel sheet act as a buffer to prevent damage to the gearbox due to hard collision. When the clamping vibration measuring member approaches and contacts the gearbox, the rotating block rotates on the surface of the rotating rod, automatically adjusting its position to fit tightly with the gearbox. After clamping is completed, the bonding sheet fits tightly with the outer surface of the gearbox, and the vibration sensor is ready to monitor the vibration. This mechanism not only firmly fixes the gearbox to prevent it from displacement during the running-in process, but also accurately measures the gearbox vibration and evaluates the gearbox's operating status and performance by analyzing the vibration data.

[0025] Fourth, the transmission running-in workbench with circulating oil purification and measurement and control effects, through the setting of the oil circulation mechanism, turns on the oil pump, and the oil in the transmission oil pool flows into the oil inlet chamber of the oil storage tank of the filter element through the oil inlet pipe under pressure. Because the density of impurities is greater than the density of oil, they sink heavily to the bottom of the oil inlet chamber. The relatively clean oil is further filtered by the filter and enters the oil outlet chamber. Impurities are intercepted on the filter, and some smaller impurities settle in the chip trough and then fall into the oil inlet chamber. The filtered clean oil then flows back to the transmission oil pool through the oil outlet pipe, realizing oil circulation purification. During the transmission running-in process, the continuously circulating oil can provide good lubrication and heat dissipation for the internal components of the transmission, while purifying the oil and removing impurities such as metal debris generated by the running-in process, ensuring stable oil performance and extending the service life of the transmission.

A vibration spring 557 is fixedly installed in the middle of the interior. The vibration spring 557 is used to amplify the vibration of the gearbox 3. The other end of the vibration spring 557 is fixedly connected to a slide plate 555. A bonding sheet 556 is fixedly installed on the side of the slide plate 555 away from the vibration spring 557. The bonding sheet 556 is pressed and adapted to the outer surface of the gearbox 3. The slide plate 555 and the bonding sheet 556 ensure better contact between the device and the surface of the gearbox 3. A vibration sensor 558 is fixedly installed on the inner wall of the plate sleeve 554. The vibration sensor 558 is used to measure the vibration of the gearbox 3.

[0051] The second embodiment, based on the first embodiment, see Figures 3 to 7 As shown, the shaft connection mechanism 4 includes a sleeve shaft member 1 41 and a sleeve shaft member 2 42. The outer surfaces of the sleeve shaft member 1 41 and the sleeve shaft member 2 42 are sleeved with a locking sleeve 43. There are two locking sleeves 43, and the two locking sleeves 43 are fixedly connected by a fastening bolt 44. The locking sleeve 43 and the fastening bolt 44 fix the sleeve shaft member 1 41 and the sleeve shaft member 2 42 together to ensure the stability of power transmission.

[0052] The shaft sleeve 41 includes a sleeve 411, which is engaged with the output end of the transmission shaft 23. One end of the sleeve 411 is provided with a docking groove 412, and the interior of the docking groove 412 is provided with an arcuate groove 413. There are six arcuate grooves 413.

[0053] The second sleeve shaft member 42 includes a second sleeve 421, which is engaged with the end of the input shaft of the transmission case 3. An annular sleeve 422 is fixedly connected to the end of the second sleeve 421. A slip ring 423 is installed inside the annular sleeve 422. A ball sleeve 424 is fixedly installed at the end of the slip ring 423. Balls 425 are installed inside the ball sleeve 424. There are six balls 425.

[0054] A positioning spring 426 is fixedly connected between the slip ring 423 and the annular sleeve 422. The positioning spring 426 is arranged inside the annular sleeve 422. The annular sleeve 422 is snap-fitted with the docking groove 412, and the ball 425 is snap-fitted with the arc groove 413. When the annular sleeve 422 is snap-fitted with the docking groove 412, the annular sleeve 422 is rotated. At this time, the ball 425 rolls in the docking groove 412. When the ball 425 approaches the arc groove 413, under the elastic force of the positioning spring 426, the ball 425 is snap-fitted with the arc groove 413.

[0055] The third embodiment, based on the first and second embodiments, see Figures 12 to 13 As shown, the oil circulation mechanism 6 includes a filter element 61, and an oil inlet pipe 62 and an oil outlet pipe 63 are fixedly connected to both sides of the filter element 61. The oil inlet pipe 62 and the oil outlet pipe 63 both pass through the workbench 1 and extend to the outside thereof. The oil inlet pipe 62 and the oil outlet pipe 63 are connected to the oil pool of the gearbox 3. An oil pump 64 is fixedly installed on the oil outlet pipe 63. The oil inlet pipe 62 introduces the oil in the oil pool of the gearbox 3 into the filter element 61, and the oil outlet pipe 63 returns the filtered oil to the oil pool of the gearbox 3 to realize oil circulation. The oil pump 64 provides power for the oil circulation to ensure that the oil can be continuously extracted, filtered and returned.

[0056] The filter element 61 includes an oil storage tank 611, and a baffle 612 is fixedly installed on the inner wall of the oil storage tank 611. The baffle 612 divides the interior of the oil storage tank 611 into two parts: an oil inlet chamber and an oil outlet chamber. A filter screen 613 is fixedly installed between the top of the baffle 612 and the inner wall of the oil storage tank 611. The filter screen 613 is arranged in the oil outlet chamber of the oil storage tank 611, and a chip leakage groove 614 is provided at the bottom of the oil outlet chamber of the oil storage tank 611. The oil storage tank 611 stores oil, the baffle 612 separates the oil inlet chamber and the oil outlet chamber, and the filter screen 613 filters the oil to remove impurities. The chip groove 614 is convenient for collecting the filtered impurities. Under the action of pressure, the oil flows into the oil inlet chamber of the oil storage tank 611 of the filter element 61 through the oil inlet pipe 62. Since the density of impurities is greater than the density of oil, they are heavier and sink to the bottom of the oil inlet chamber. The relatively clean oil is further filtered by the filter screen 613 and enters the oil outlet chamber. The impurities are intercepted on the filter screen 613. Some impurities with smaller particles are deposited in the chip groove 614 and then fall into the oil inlet chamber. The clean oil after filtration flows back to the oil pool of the gearbox 3 through the oil outlet pipe 63, thereby realizing the circulation and purification of the oil.

[0057] When in use, the gearbox 3 is placed on the top of the mounting plate 9, the shaft connection mechanism 4 is assembled, the shaft sleeve 1 411 of the shaft sleeve 1 41 is clamped to the output end of the transmission shaft 23, the shaft sleeve 2 421 of the shaft sleeve 2 42 is clamped to the end of the input shaft of the gearbox 3, and then the two locking sleeves 43 are respectively sleeved on the outer surfaces of the shaft sleeve 1 41 and the shaft sleeve 2 42, and they are fixedly connected by fastening bolts 44 to complete the power connection between the drive mechanism 2 and the gearbox 3. At this time, the annular sleeve 422 of the shaft sleeve 2 42 is inserted into the docking groove 412 of the shaft sleeve 1 41, the ball 425 is clamped with the arc groove 413, and the positioning spring 426 between the slip ring 423 and the annular sleeve 422 can play a role in buffering and adapting to position deviation;

[0058] When the gearbox 3 is moved to the left, the spring 547 is engaged with the spring 548 and the spring 549 is engaged with the spring 551. When the gearbox 3 is moved to the right, the spring 547 is engaged with the spring 548 and the spring 549 is engaged with the spring 551. When the gearbox 3 is moved to the left, the spring 547 is engaged with the spring 548 and the spring 549 is engaged with the spring 551.

[0059] The motor 22 is started, and the power output by the motor 22 is transmitted to the shaft connection mechanism 4 through the transmission shaft 23, thereby driving the input shaft of the gearbox 3 to rotate, so that the gearbox 3 begins to enter the running-in test state;

[0060] During the running-in process of the gearbox 3, the oil circulation mechanism 6 starts to work, the oil pump 64 is started, and the oil in the gearbox 3 oil pool is pumped out and transported to the oil inlet chamber of the oil storage tank 611 of the filter element 61 through the oil inlet pipe 62. Since the density of impurities is greater than that of oil, they are heavier and sink to the bottom of the oil inlet chamber. The relatively clean oil is further filtered by the filter 613 and enters the oil outlet chamber. The impurities are intercepted on the filter 613, and some smaller impurities are deposited in the chip leakage groove 614 and then fall into the oil inlet chamber. The clean oil after filtering flows back to the gearbox 3 oil pool through the oil outlet pipe 63, thus realizing the circulation and purification of the oil.

[0061] Since the gearbox 3 generates vibration during the running-in process, the vibration is transmitted to the slide plate 555 through the bonding sheet 556. The slide plate 555 compresses the vibration spring 557, and the vibration spring 557 amplifies the vibration. The vibration sensor 558 installed on the inner wall of the plate sleeve 554 collects vibration data in real time and transmits the data to the control console 7 so that the operator can promptly understand the vibration status of the gearbox 3 and determine whether it is operating normally and whether there are any potential faults.

[0062] After the running-in test is completed, the motor 22 in the drive mechanism 2 is turned off, the operation of the gearbox 3 is stopped, and the oil pump 64 is turned off to stop the oil circulation;

[0063] The clamping cylinder 52 is operated to retract, thereby driving the telescopic rod 53, the buffer member 54 and the clamping vibration measuring member 55 away from the gearbox 3, releasing the clamping of the gearbox 3, and completing the operation.

[0064] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device.
