Description

Technical Field

[0001] The present invention relates to the technical field of bearing performance testing, and more specifically, to a marine thrust bearing performance testing device and a testing method thereof. Background Art

[0002] A bearing is an important component in modern mechanical equipment. Its main function is to support a mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotational accuracy.

[0003] In the application field of electric ships, bearings are widely used. For example, a large number of bearing structures (such as deep groove ball bearings) are adopted between the propeller rotating shaft of a ship or other thrust components to provide thrust to the hull.

[0004] In a ship, some special bearings are also used. While providing rotational support to the shaft, they can also provide thrust to the shaft. And to improve the waterproof effect of the bearing, a small gap needs to be maintained between the inner ring and the outer ring of the bearing. In actual applications, for example, in some harsh environments, due to certain factors, the rotating shaft tilts, which in turn causes the axis of the inner ring to be inclined to a certain extent with respect to the axis of the outer ring, and as a result, contact may occur at the edge. Since the outer ring is fixed to the equipment and the inner ring rotates with the working shaft, fixed contact point friction will occur between the two ends of the inner ring and the outer ring. This fixed contact point friction continues. Therefore, for this type of thrust bearing, it is necessary to conduct friction tests on the fixed contact points between the two ends of the inner ring and the outer ring.

[0005] However, the existing marine thrust bearing performance testing devices do not consider the above situation. Therefore, there is a need for a device that can test the number of revolutions that the thrust bearing can operate when a fault occurs in the above-mentioned type of thrust bearing, resulting in fixed contact point friction between the inner ring and the outer ring. The purpose is to test whether the thrust bearing can continue to operate to meet the design requirements under the condition of fixed contact point friction between the inner ring and the outer ring.

Detailed implementation manners

[0038] The present application will be further described in detail below with reference to the accompanying drawings. It is necessary to point out here that the following detailed implementation manners are only used to further illustrate the present application and should not be construed as limiting the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0039] Refer to the accompanying drawings of the specification Figures 1 to 8 , a marine thrust bearing performance testing device, including a frame 1, an inspection table 2 is installed on the frame 1, a first bearing seat 21 and a second bearing seat 22 are installed on the inspection table 2, and both the first bearing seat 21 and the second bearing seat 22 are used for installing a bearing member 213. A first drive motor 23 is also installed on the first bearing seat 21. A universal joint member 234 is used to connect the working shaft 231 at the center of the bearing member 213 and the output end of the first drive motor 23. An alignment mechanism 25 is provided at one end of the working shaft 231 away from the first drive motor 23. An inclination detection assembly is provided between the first bearing seat 21 and the second bearing seat 22. When the alignment mechanism 25 drives the working shaft 231 to tilt in the horizontal direction, the inclination angle of the working shaft 231 between the first bearing seat 21 and the second bearing seat 22 is detected by the inclination detection assembly. The alignment mechanism 25 includes a first linear drive mechanism 253. A revolution counter 254 is provided at the output end of the first linear drive mechanism 253, and the revolution counter 254 is installed at one end of the working shaft 231 away from the first drive motor 23.

[0040] It should be noted that when the linear drive mechanism 253 moves in the extending direction, the inner ring 2132 is driven by the working shaft 231 to tilt to one side, so that contact points A1 and A2 are formed between the two ends of the inner wall of the outer ring 2131 and the outer side of the inner ring 2132, and the contact points A1 and A2 are arranged diagonally corresponding to each other. When the linear drive mechanism 253 moves in the contracting direction, the inner ring 2132 is driven by the working shaft 231 to tilt to the other side, so that contact points B1 and B2 are formed between the two ends of the inner wall of the outer ring 2131 and the outer side of the inner ring 2132, and the contact points B1 and B2 are arranged diagonally corresponding to each other. The contact points A1 and B1 are arranged axially corresponding to each other.

[0041] In this embodiment, the implementation scenario is specifically as follows: Two bearing members 213 are respectively installed on the first bearing seat 21 and the second bearing seat 22. The working shaft 231 is driven by the orientation adjustment mechanism 25 to tilt in the horizontal direction. The inclination angle of the working shaft 231 between the first bearing seat 21 and the second bearing seat 22 is detected by the inclination angle detection component. After reaching the required angle for testing, at this time, contact points A1 and A2 are formed between the outer ring 2131 and the inner ring 2132. The first drive motor 23 is started to drive the working shaft 231 to rotate continuously. The number of turns of the inner ring 2132 is obtained through the revolution counter 254. In order to obtain accurate data, the inclination direction of the inner ring 2132 is changed, and the other side of the outer ring 2131 is continued to be tested. The number of turns of this test is the same as that of the previous test. According to the required number of turns of the test, when the required number of operating turns is reached, it can be judged as a qualified product, otherwise it is unqualified. By tilting the inner ring 2132 to the limit state, fixed contact points A1 and A2 are manufactured between the outer ring 2131 and the inner ring 2132, and then fixed contact points B1 and B2 are manufactured by tilting in the reverse direction, so as to meet the test condition of whether the bearing member 213 can reach the design requirements when continuously operating under the condition of friction at the fixed contact points between the outer ring 2131 and the inner ring 2132.

[0042] Furthermore, the orientation adjustment mechanism 25 further includes an arc-shaped seat 251. An activity seat 252 is slidably arranged on the top of the arc-shaped seat 251. The revolution counter 254 is fixedly installed on the activity seat 252. The output end of the linear drive mechanism 253 is rotationally connected with the activity seat 252. A guiding component is installed on the activity seat 252. When the linear drive mechanism 253 pushes the activity seat 252 to move, the activity seat 252 swings in an arc-shaped path with the connection point of the universal joint member 234 as the center through the guiding component.

[0043] It should be noted that the arc-shaped seat 251 is an arc-shaped component, and its center coincides with the center of the universal joint member 234. The activity seat 252 slides along the top of the arc-shaped seat 251 in an arc-shaped path.

[0044] Further, the guiding assembly includes a guiding column 255, which is fixedly connected to the movable seat 252. The movable seat 252 penetrates through the inside of the arc-shaped seat 251. A limiting disk 256 is sleeved at the bottom end of the guiding column 255. A ball groove 2561 is formed at the top of the limiting disk 256. A ball 2562 is rotatably arranged inside the ball groove 2561. An elastic sleeve member 2563 is fixedly arranged between the outer side of the ball 2562 and the inner wall of the ball groove 2561. A limiting nut 257 is arranged at the bottom of the limiting disk 256, and the limiting nut 257 is in threaded connection with the guiding column 255. The limiting nut 257 is used to limit the limiting disk 256, so that the top of the limiting disk 256 is closely attached to the bottom of the arc-shaped seat 251.

[0045] It should be noted that by tightening the limiting nut 257 to make the ball 2562 at the top of the limiting disk 256 press against the bottom of the arc-shaped seat 251, the vertical positioning of the guiding column 255 can be realized, which is convenient for the movable seat 252 to accurately slide along the arc-shaped opening of the arc-shaped seat 251. At the same time, through the arrangement of the elastic sleeve member 2563 for elastic support, it is avoided that the connection between the revolution counter 254 and the working shaft 231 is disconnected when the movable seat 252 has a vertical offset during the working process.

[0046] Further, a linear guide rail 232 is installed at the bottom of the first driving motor 23, and the linear guide rail 232 is used to support the first driving motor 23 to slide axially along the working shaft 231. A second linear driving mechanism 26 is arranged at one end of the first driving motor 23 away from the working shaft 231, and the second linear driving mechanism 26 is used to push the first driving motor 23 to move. A pressure sensor 27 is arranged between the first driving motor 23 and the second linear driving mechanism 26, and the pressure sensor 27 is used to monitor the axial thrust of the second linear driving mechanism 26 on the first driving motor 23.

[0047] It should be noted that when the outer ring 2131 and the inner ring 2132 are parallel, an axial load is applied to the first driving motor 23 and the working shaft 231 through the second linear driving mechanism 26 to test the axial load performance of the bearing member 213.

[0048] Further, the inclination detection assembly includes an angle sensor transmitting end 242 and an angle sensor receiving end 243. The angle sensor receiving end 243 is inclined. The angle sensor transmitting end 242 emits monitoring light to the working shaft 231, and the monitoring light reflected by the working shaft 231 is received by the angle sensor receiving end 243.

[0049] It should be noted that two groups of the angle sensor receiving ends 243 are arranged on both sides of the angle sensor transmitting end 242. As an example, only one group is arranged in the attached drawings. When the angle sensor receiving end 243 receives the monitoring light signal of the angle sensor transmitting end 242, it indicates that the inclination angle of the working shaft 231 meets the requirements.

[0050] Further, a control box 233 is provided on one side of the first driving motor 23, and the control box 233 is used to control the rotation speed of the first driving motor 23. An installation base 24 is provided on one side of the first bearing seat 21. A temperature detector 241 is installed on the installation base 24, and the temperature detector 241 is used to monitor the temperature of the bearing members 213 on the first bearing seat 21 and the second bearing seat 22. The transmitting end 242 and the receiving end 243 of the angle sensor are both installed on the installation base 24.

[0051] Further, a master control box 3 is also installed on the frame 1. The master control box 3 is located above the detection table 2. The master control box 3 is used to provide power. A display screen is embedded on the master control box 3, and the display screen is used to display the data of the control box 233, the temperature detector 241, the revolution counter 254, the pressure sensor 27, and the inclination detection assembly.

[0052] Refer to the attached Figures 9 to 11 description. Through the above solution, a set of data of the fixed contact points of the first contact point A1 and the second contact point A2, as well as a set of data of the fixed contact points of the third contact point B1 and the fourth contact point B2 can be obtained. In order to obtain more data, more fixed contact points need to be tested.

[0053] To solve this problem, the present invention also provides the following technical solution: Both the first bearing seat 21 and the second bearing seat 22 include a base 211. A shaft seat 212 is installed on the base 211. A positioning bolt 214 is threadedly connected to the shaft seat 212, and the positioning bolt 214 is used to position the bearing member 213 within the shaft seat 212. A ring adjusting mechanism 4 is provided on one side of both the first bearing seat 21 and the second bearing seat 22, and the ring adjusting mechanism 4 is used to adjust the rotation angle of the outer ring 2131.

[0054] It should be noted that the positioning bolt 214 passes through the shaft seat 212 to position the bearing member 213.

[0055] Further, the ring adjusting mechanism 4 includes a motor box 40. A ring adjusting wheel 41 is installed on the motor box 40. A third linear driving mechanism 42 is installed at the bottom of the motor box 40. A second driving motor 401 is installed inside the motor box 40. The second driving motor 401 is drivingly connected to the ring adjusting wheel 41. The third linear driving mechanism 42 drives the motor box 40 to move upward, so that the ring adjusting wheel 41 abuts against the outer ring 2131. By rotating the ring adjusting wheel 41, the outer ring 2131 rotates synchronously.

[0056] It should be noted that the third linear driving mechanism 42 is a cylinder or a linear lead screw. The second driving motor 401 is drivingly connected to the ring adjusting wheel 41 through a belt or a gear.

[0057] Furthermore, a first transmission component 43 and a second transmission component 44 are installed on the base 211, and the first transmission component 43 and the second transmission component 44 are respectively located on both sides of the end of the shaft seat 212. The output ends of the first transmission component 43 and the second transmission component 44 are both rotatably connected with a guide wheel 45. When the motor box 40 moves downward, the corresponding guide wheel 45 is pressed against the outer side of the bearing member 213 through the first transmission component 43 and the second transmission component 44, and the guide wheel 45 slides along the outer surface of the bearing member 213.

[0058] It should be noted that the guide wheel 45 rolls along the axial direction of the bearing member 213 to prevent the bearing member 213 from rotating uncontrollably under external force, which affects the accuracy of the adjustment angle.

[0059] Furthermore, both the first transmission component 43 and the second transmission component 44 include a first transmission rod 431. One end of the first transmission rod 431 is rotatably connected with a second transmission rod 432 and a third transmission rod 433, and the second transmission rod 432 and the third transmission rod 433 are fixedly connected. The guide wheel 45 is rotatably installed on the second transmission rod 432. The end of the third transmission rod 433 away from the first transmission rod 431 is rotatably connected with a fourth transmission rod 434. Extension rods 402 are installed at both ends of the motor box 40, and the extension rods 402 are rotatably connected with the fourth transmission rod 434. When the motor box 40 moves upward, the guide wheel 45 is moved away from the outer side of the bearing member 213 through the extension rods 402 and the corresponding first transmission component 43 and second transmission component 44.

[0060] It should be noted that the second transmission rod 432 and the third transmission rod 433 are connected at a fixed angle. When one end of the second transmission rod 432 approaches the bearing member 213, one end of the third transmission rod 433 moves away from the bearing member 213.

[0061] Even further, an angle disk 46 is provided between the third transmission rod 433 and the fourth transmission rod 434. When the bearing member 213 is moved out of the shaft seat 212, the angle disk 46 is pressed against the outer side of the outer ring 2131, so that the angle disk 46 and the outer ring 2131 rotate synchronously. The end of the third transmission rod 433 is rotatably connected with a rotating shaft, the end of the fourth transmission rod 434 is fixed to the rotating shaft, and an indicating needle 461 is fixedly provided at one end of the rotating shaft. The indicating needle 461 is rotatably arranged on one side of the angle disk 46.

[0062] It should be noted that the angle disk 46 rotates synchronously with the bearing member 213. Angle lines are engraved on the side surface of the angle disk 46. The rotation adjustment angle of the bearing member 213 can be known through the cooperation of the indicating needle 461 and the angle lines. In order to ensure that both the adjusting ring wheel 41 and the angle disk 46 rotate synchronously with the bearing member 213, anti-slip sleeves are sleeved on the outer peripheries of the adjusting ring wheel 41 and the angle disk 46.

[0063] In this embodiment, the implementation scenario is as follows: First, unlock the positioning bolt 214 from the bearing member 213, then remove the revolution counter 254 from the working shaft 231. Push one-third of the bearing member 213 out of the shaft seat 212 by the linear drive mechanism two 26. At this time, the guide wheels 45 on both sides roll axially along the outer side of the bearing member 213 to play a guiding role. Start the linear drive mechanism three 42 to drive the ring adjusting mechanism 4 to rise, so that the ring adjusting wheel 41 contacts the outer side of the bearing member 213. At this time, the angle dial 46 also contacts the outer side of the bearing member 213, and the guide wheels 45 disengage from the outer side of the bearing member 213. Drive the ring adjusting wheel 41 to rotate by the drive motor two 401, so that the outer ring 2131 rotates, and the angle dial 46 rotates with the outer ring 2131. Observe the angle line indicated by the indicating needle 461 to determine the adjusted angle of the outer ring 2131. Pull down the motor box 40 to make the guide wheels 45 contact the outer side of the bearing member 213 again. Retract the bearing member 213 back into the shaft seat 212 by the linear drive mechanism two 26. Finally, install the revolution counter 254 to perform the test work. Overall, by accurately adjusting the rotation angle of the bearing member 213, the space between the outer ring 2131 and the inner ring 2132 is divided into several groups of fixed contact points, obtaining more representative fixed contact point data to ensure the accuracy of the test results.

[0064] The present invention also provides a method for testing the performance of a marine thrust bearing, which specifically includes the following steps:

[0065] S1. Fix and install two groups of bearing members 213 on the bearing seat one 21 and the bearing seat two 22 respectively, and pass the working shaft 231 through the inner rings 2132 of the two groups of bearing members 213. Then connect the working shaft 231 to the output end of the drive motor one 23 through a universal joint;

[0066] S2. Drive the working shaft 231 to deflect around the universal joint by the linear drive mechanism one 253, and deflect to the required test angle, and make the axis of the inner ring 2132 tilt relative to the axis of the outer ring 2131;

[0067] S3. Drive the working shaft 231 to rotate by the drive motor one 23, and calculate the number of rotations of the working shaft 231 by the revolution counter 254 to determine whether the working shaft 231 rotates normally within the specified number of rotations. If so, proceed to the next step. If not (phenomena such as the working shaft 231 cannot rotate, jitter occurs, or rotation is blocked), then determine that the bearing member 213 is unqualified;

[0068] S4. Drive the working shaft 231 to deflect reversely around the universal joint to another required test angle by the linear drive mechanism one 253, and repeat step S3;

[0069] S5. Remove and take out two sets of bearing parts 213 from the first bearing housing 21 and the second bearing housing 22. After rotating the outer ring 2131 of the bearing part 213 (the rotation angle can be any angle within 360° except 180° and 360°, and repeat steps S1 to S4), detect multiple sets of data until the detection is completed. In each detection of the bearing part 213, within the specified number of turns, the working shaft 231 can rotate normally, that is, it is determined that the bearing part 213 is qualified.

[0070] Working principle:

[0071] Install the two bearing parts 213 on the first bearing housing 21 and the second bearing housing 22 respectively, and detect the inclination angle of the working shaft 231 located between the first bearing housing 21 and the second bearing housing 22 through the inclination detection component.

[0072] Start the first driving motor 23 to drive the working shaft 231 to rotate continuously, and obtain the number of turns of the inner ring 2132 rotating through the revolution counter 254 in order to obtain accurate data.

[0073] Change the inclination direction of the inner ring 2132 and continue to test the other side of the outer ring 2131.

[0074] First release the locking of the bearing part 213 by the positioning bolt 214, then remove the revolution counter 254 from the working shaft 231, and push one-third of the bearing part 213 out of the shaft seat 212 through the push of the second linear drive mechanism 26.

[0075] Start the third linear drive mechanism 42 to drive the ring adjusting mechanism 4 to rise, so that the ring adjusting wheel 41 contacts the outer side of the bearing part 213, drive the ring adjusting wheel 41 to rotate through the second driving motor 401, so that the outer ring 2131 rotates, and the angle dial 46 rotates following the outer ring 2131.

[0076] Observe the angle line indicated by the indicating needle 461 to determine the angle adjusted by the outer ring 2131.

[0077] The above embodiments only represent several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
