Description

Technical Field

[0001] This invention relates to the field of bearing vibration detection, and in particular to a bearing vibration detection device. Background Technology

[0002] Bearings are important components in mechanical equipment. Their main function is to support rotating mechanical bodies, reduce the coefficient of friction during their movement, and ensure their rotational accuracy. During operation, bearing vibration refers to all movements that deviate from the ideal position other than some inherent movements between bearing parts that are required by the function. After the bearing is manufactured, an oscillating structure is needed to apply oscillation to the bearing ring surface.

[0003] Currently, most existing bearing vibration testing equipment only has one testing station, resulting in low testing efficiency. At the same time, its power source only drives the rotation of a single bearing mounting shaft to complete the testing, which causes a great deal of energy waste during testing. Therefore, there is a need for a bearing vibration testing device that can simultaneously support multiple testing stations with a single power source. Summary of the Invention

[0004] This invention provides a bearing vibration detection device with multiple detection stations powered by the same source, which improves detection efficiency and energy utilization.

[0005] The objective of this invention is achieved through the following technical solution: A bearing vibration detection device includes a polyhedral support and a platform plate fixed to the upper end of the polyhedral support. The platform plate is rotatably mounted with an inclined wheel at the center of the polyhedral support. Multiple installation and detection mechanisms are evenly installed on the platform plate in the circumferential direction, and each installation and detection mechanism can be controllably transmitted to the inclined wheel.

[0006] Preferably, each of the installation and testing mechanisms includes a mounting seat that is radially limited and slides on the platform plate. An adjusting screw is threaded through the mounting seat and rotatably connected to the polyhedral support. A mounting frame is threaded through the mounting seat. A transmission wheel that rotatably contacts and drives the inclined wheel is located at the lower end of the mounting frame. A rotating shaft for mounting bearings is rotatably located at the upper end of the mounting frame. The transmission wheel is connected to the rotating shaft.

[0007] Preferably, the mounting bracket includes two sliding rods that pass through the mounting base. The lower ends of the two sliding rods are fixed to a lower base, and the upper ends of the two sliding rods are fixed to an upper base. The transmission wheel rotates on the lower base, and the rotating shaft rotates on the upper base. A spring I is provided between the lower base and the mounting base.

[0008] Preferably, an electric telescopic rod is installed at the lower end of the upper seat, and the telescopic end of the electric telescopic rod corresponds to the mounting seat.

[0009] Preferably, the rotating shaft has a shoulder seat in the middle for mounting the bearing, and the rotating shaft has a threaded end at the end away from the center of the inclined wheel. A mounting nut is threaded onto the threaded end, and a tightening sleeve is provided at the end of the mounting nut near the shoulder seat.

[0010] Preferably, the upper seat is equipped with a mounting plate at the end away from the center of the inclined wheel. The mounting plate is coaxial with the rotating shaft and has multiple tightening mechanisms evenly installed around the circumference for tightening the outer ring of the bearing.

[0011] Preferably, the clamping mechanism includes a slider seat, a support arm fixed on the slider seat, a square slide rod passing through the support arm, a semi-circular block near the center end of the square slide rod near the center end of the mounting plate, a piezoelectric sensor near the center end of the support arm near the center end of the mounting plate, and a spring II between the semi-circular block and the piezoelectric sensor.

[0012] Preferably, an anti-slip rubber strip is provided axially at the top of the semi-circular block.

[0013] Preferably, the mounting plate is provided with a plurality of radial slides evenly distributed around the circumference, and the plurality of slider seats slide within the plurality of radial slides respectively.

[0014] Preferably, each mounting plate has a control plate rotating near the center of the inclined wheel. The control plate has multiple control holes evenly distributed around its circumference, and multiple slider seats slide in the multiple control holes respectively. A worm gear rotates at the upper end of the mounting plate for meshing and transmission with the worm wheel ring at the outer end of the control plate.

[0015] The beneficial effects of this invention are as follows: The inclined wheel 104 enables controllable transmission to each installation and testing mechanism, improving energy utilization. It also allows for simultaneous bearing vibration testing at each installation and testing mechanism, thus improving testing efficiency. Attached Figure Description

Detailed Implementation

[0018] like Figure 1-10 As shown, a bearing vibration detection device is described in detail: A bearing vibration detection device includes a polyhedral support 101 and a platform plate 102 fixed to the upper end of the polyhedral support 101. The platform plate 102 and the polyhedral support 101 have a sloping wheel 104 rotating at their center. The platform plate 102 is circumferentially equipped with a plurality of installation and detection mechanisms, each of which can be controllably connected to the sloping wheel 104.

[0019] In use, the bearing to be tested is installed on the mounting and testing mechanism, and the mounting and testing mechanism is controlled to contact the inclined wheel 104, forming a transmission between the inclined wheel 104 and the mounting and testing mechanism, thereby forming the test of the bearing; by corresponding multiple mounting and testing mechanisms with each side of multiple body brackets 101, multiple testing stations are formed, and the required mounting and testing mechanism is individually controlled to transmit the transmission between it and the inclined wheel 104 to complete the test, thereby improving the testing efficiency and energy utilization rate; It should be noted that a power motor is installed at the lower middle part of the polyhedral support 101 to drive the inclined wheel 104.

[0020] Further: Each of the aforementioned installation and testing mechanisms includes a mounting seat 103 that is radially limited and slides on the platform plate 102. An adjusting screw 105 is threaded through the mounting seat 103 and is rotatably connected to the polyhedral support 101. A mounting frame is threaded through the mounting seat 103. A transmission wheel 204 is rotatably connected to the lower end of the mounting frame and is in contact with the inclined wheel 104. A rotating shaft 301 for mounting bearings is rotatably connected to the upper end of the mounting frame. The transmission wheel 204 is rotatably connected to the rotating shaft 301.

[0021] Rotating the adjusting screw 105 allows the mounting base 103 to move axially along the adjusting screw 105 via the threaded engagement between the adjusting screw 105 and the mounting base 103. This causes the mounting bracket to move closer to or further away from the center of the inclined wheel 104, thereby changing the contact position between the transmission wheel 204 and the inclined wheel 104. With the rotational speed of the inclined wheel 104 remaining constant, the closer the contact position between the transmission wheel 204 and the inclined wheel 104 is to the center of the inclined wheel 104, the slower the rotational speed of the transmission wheel 204. Conversely, the further the contact position between the transmission wheel 204 and the inclined wheel 104 is to the center of the inclined wheel 104, the faster the rotational speed of the transmission wheel 204. This allows for adjustment of the speed at which the bearing of the mounting and testing mechanism is tested.

[0022] Further: The mounting bracket includes two sliding rods 201 that pass through the mounting base 103. The lower ends of the two sliding rods 201 are fixed to a lower base 202, and the upper ends of the two sliding rods 201 are fixed to an upper base 203. The transmission wheel 204 rotates on the lower base 202, and the rotating shaft 301 rotates on the upper base 203. A spring I 205 is provided between the lower base 202 and the mounting base 103.

[0023] The spring force of spring I205 can push the lower seat 202 downward, which in turn drives the transmission wheel 204 to press against the inclined surface of the inclined wheel 104, increasing the friction between the two and ensuring the efficiency of the transmission of the inclined wheel 104 to the transmission wheel 204.

[0024] Further: An electric telescopic rod 206 is installed at the lower end of the upper seat 203, and the telescopic end of the electric telescopic rod 206 corresponds to the mounting base 103.

[0025] With the electric telescopic rod 206 in place, when the testing mechanism needs to be stopped from rotating, the electric telescopic rod 206 is activated, causing its telescopic end to extend downwards until it presses against the mounting base 103. This, in turn, pushes the mounting frame upwards, thereby causing the transmission wheel 204 to separate from the inclined wheel 104, thus stopping the testing mechanism from rotating and facilitating the installation of the bearing to be tested.

[0026] like Figure 5-6 As shown: The rotating shaft 301 has a shoulder seat 302 in the middle for mounting bearings. The rotating shaft 301 has a threaded end 303 at the center end away from the inclined wheel 104. A mounting nut 304 is threaded onto the threaded end 303. A tightening sleeve 305 is provided at the end of the mounting nut 304 near the shoulder seat 302.

[0027] When installing the bearing to be tested, the bearing is fitted onto the rotating shaft 301 through the threaded end 303 until the inner ring of the bearing is fitted onto the shoulder seat 302. Then, the mounting nut 304 is screwed onto the threaded end 303 through the thread, which causes the clamping sleeve 305 to clamp the inner ring of the bearing. The inner ring of the bearing is then clamped and fixed by the shoulder seat 302 and the clamping sleeve 305, thus completing the installation of the bearing.

[0028] like Figure 7-10 As shown: The upper seat 203 is equipped with a mounting plate 401 at the center end away from the inclined wheel 104. The mounting plate 401 is coaxially arranged with the rotating shaft 301 and has multiple tightening mechanisms evenly installed around its circumference for tightening the outer ring of the bearing.

[0029] By setting up multiple clamping mechanisms, the outer ring surface of the bearing can be clamped evenly in the circumference, thus fixing the outer ring of the bearing.

[0030] Further: The clamping mechanism includes a slider seat 501, a support arm 502 fixed on the slider seat 501, a square slide rod 503 passing through the support arm 502, a semi-circular block 504 near the center end of the square slide rod 503 near the center end of the mounting plate 401, a piezoelectric sensor near the center end of the support arm 502 near the center end of the mounting plate 401, and a spring II 505 between the semi-circular block 504 and the piezoelectric sensor.

[0031] The spring force of spring II 505 pushes the semicircular block 504 towards the center of the bearing, thereby pressing the outer ring of the bearing. When the inclined wheel 104 drives the transmission wheel 204 to rotate through friction, the transmission shaft 301 rotates, thereby driving the inner ring of the bearing to rotate. Thus, when the bearing vibrates, the semicircular block 504 will vibrate accordingly. The pressure on the semicircular block 504 is transmitted to the piezoelectric sensor through spring II 505. The piezoelectric sensor converts it into an electrical signal that can be received and displayed, and transmits it to the display through the sensing line.

[0032] Further: The anti-slip rubber strip 504 is axially provided at the top of the semicircular block 504 to increase the friction between the semicircular block 504 and the outer ring of the bearing. At the same time, since the anti-slip rubber strip 504 is axially arranged, when it is pressed against the outer ring of the bearing, the anti-slip rubber strip 504 automatically undergoes elastic deformation, thereby causing both sides of the semicircular block 504 to press against the outer ring of the bearing simultaneously, ensuring rigid contact between the two and preventing the anti-slip rubber strip 504 from affecting the detection of bearing vibration.

[0033] Further: The mounting plate 401 is provided with a plurality of radial slides 402 evenly distributed in the circumferential direction, and a plurality of slider seats 501 slide in the plurality of radial slides 402 respectively.

[0034] By sliding the slider seat 501 within the radial slide rail 402, the semicircular block 504 can be moved closer to or further away from the bearing. This allows the clamping mechanism to be controlled to move away from the bearing during installation or disassembly, thereby improving the efficiency of bearing installation or disassembly.

[0035] Further: Each mounting plate 401 has a control plate 403 rotating near the center of the inclined wheel 104. The control plate 403 has multiple control holes 405 evenly arranged in the circumferential direction. Multiple slider seats 501 slide in the multiple control holes 405 respectively. A worm gear 404 rotates at the upper end of the mounting plate 401 for meshing and transmission with the worm wheel ring at the outer end of the control plate 403.

[0036] Rotating the worm gear 404 enables the control disk 403 to rotate relative to the mounting disk 401 through meshing and transmission with the worm wheel ring at the outer end of the control disk 403. This rotation, in turn, pushes multiple slider seats 501 to move synchronously closer to or further away from the bearings within multiple radial slides 402 via multiple control holes 405. Furthermore, it simultaneously controls multiple clamping mechanisms to move away from or closer to the bearings, thereby improving the efficiency of bearing installation or removal.
