Description

Technical Field

[0001] The invention relates to the technical field of gear clearance detection, and in particular to a gear clearance detection device for a reducer. Background Art

[0002] In mechanical transmission systems, gear meshing clearance is one of the important factors affecting transmission efficiency, stability and service life. In order to ensure the normal operation of the gear transmission system, accurate measurement and control of gear meshing clearance is essential. Traditional gear clearance detection methods mainly include the lead bite method and the plug gauge method, each of which has its own characteristics and application scenarios.

[0003] The lead bite method is a method of determining the gear clearance by placing a soft lead sheet in the gear gap, then rotating the gear to compress and deform the lead sheet, and finally measuring the thickness of the lead sheet. The deformed thickness of the lead sheet reflects the actual clearance value when the gears are meshing.

[0004] The plug gauge method is a method of measuring gear clearance by using a series of plug gauges (thickness gauges) of standard thickness. The plug gauge is composed of metal sheets of different thicknesses, each of which represents a standard thickness value.

[0005] The lead bite method and the plug gauge method are traditional gear clearance measurement methods, each with its own unique advantages and limitations. The lead bite method is simple to operate, intuitive, and suitable for rapid on-site detection, but the accuracy is low. The plug gauge method has high accuracy and a wide range of applications, but the operation is relatively cumbersome, requiring operators to inspect and record the gears one by one, both of which require manual operation, are highly complex, and are prone to human errors.

[0027] 1.

The two gears are meshed with each other. When in use, the operator can use the driving component to move the position of the bracket. When the bracket moves upward to a preset position, the provided positioning part can fix the gears on the positioning shaft and the detection shaft. When the driving component moves the bracket to the preset position, the moving bracket can be stopped and the detection shaft can be rotated. Because the two gears are fixed on the positioning shaft and the detection shaft by the positioning part, the positioning shaft does not rotate. When the detection shaft is rotated, the detection shaft can be reciprocated clockwise and counterclockwise. When the detection shaft rotates, the detection shaft can be positioned by the positioning part. The gears on the shaft rotate, with one gear being fixed and the other gear rotating back and forth clockwise and counterclockwise to detect the rotation angle and swing amplitude of the gears on the shaft, and the gap after the two gears are meshed can be determined.

At the same time, when the bracket moves upward to a preset position, the provided recording pen can contact the recording paper, and when the detection shaft rotates and swings, the recording pen can rotate with it. After the tip of the recording pen contacts the recording paper, as the recording pen swings, the ink of the recording pen can be used to record the rotation path of the detection shaft on the recording paper, thereby achieving the purpose of automatically recording the measurement value for subsequent tracing.

[0028] 2. The present invention resets the position of the bracket after the detection is completed so that the positioning part cancels the fixation of the gear, removes the gear, puts in two gears of the next batch, and continues to move the bracket upward through the driving part. When the bracket moves upward to the preset position, the position of the recording paper can also be moved. The first box body rolls up the recording paper and the second box body releases the recording paper, so that the recording paper can be moved a preset distance, so that the measurement value recorded last time is rolled up in the first box body, and the new end of the recording paper is used for recording the next time, thereby achieving the purpose of classified recording. Compared with the detection equipment in the prior art, the present application only requires the operator to take and put the gear and turn on or off the driving part. During the detection, the detection part set can intuitively display the value of this detection, and the recording part set can record the value of this detection for subsequent tracing, which solves the problem that the detection operation in the prior art is relatively cumbersome, and the operator needs to detect and record the gears one by one, which requires manual operation, is highly complex, and is prone to human errors.

[0050] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0051] refer to Figure 1-Figure 13 , a reducer gear clearance detection device, comprising:

[0052] Inspection tooling 100;

[0053] A positioning shaft 101 and a detection shaft 102 are provided on the detection fixture 100, and the gear to be detected is placed on the positioning shaft 101 and the detection shaft 102;

[0054] The positioning part 103 provided in the positioning shaft 101 and the detection shaft 102 is used to fix the gears on the positioning shaft 101 and the detection shaft 102;

[0055] A detection unit 104 and a recording unit 105 provided on the detection tool 100;

[0056] A bracket 106 is provided in the detection tool 100, and the bracket 106 can move up and down. When the bracket 106 moves upward to a preset position, the positioning portion 103 can fix the gear;

[0057] A driving component provided on the detection fixture 100, the driving component can move the position of the bracket 106, the driving component can stop the moving bracket 106 and rotate the detection shaft 102 when the bracket 106 is moved to a preset position, and the detection shaft 102 can reciprocate clockwise and counterclockwise;

[0058] The recording unit 105 includes a first box body 107 and a second box body 108 disposed on the detection tooling 100. A recording paper 109 is disposed in the first box body 107. The other end of the recording paper 109 is disposed in the second box body 108. A recording pen 110 is disposed at the bottom of the recording paper 109. The recording pen 110 can rotate with the detection axis 102 with the detection axis 102 as the center.

[0059] Wherein, the recording paper 109 can move a preset distance when the bracket 106 moves to a preset position;

[0060] By setting up the detection fixture 100, the operator can place the two gears that need to detect the gear gap on the fixed shaft and the detection shaft 102 on the detection fixture 100 respectively, and the two gears are meshed with each other. When in use, the operator can use the driving component to move the position of the bracket 106. When the bracket 106 moves upward to a preset position, the provided positioning portion 103 can fix the gears on the positioning shaft 101 and the detection shaft 102. When the driving component moves the bracket 106 to the preset position, the moving bracket 106 can be stopped and the detection shaft 102 can be rotated. Because the two gears are fixed to the positioning shaft 101 and the detection shaft 102 by the positioning portion 103, and the positioning shaft 101 does not rotate, when the detection shaft 102 is rotated, the positioning shaft 101 does not rotate. When the detection shaft 102 is rotated, the detection shaft 102 can be rotated clockwise and counterclockwise. When the detection shaft 102 rotates, the gear on the detection shaft 102 can be rotated through the positioning part 103. One of the gears is fixed and the other gear rotates clockwise and counterclockwise to detect the rotation angle and swing amplitude of the gear on the detection shaft 102. The gap after the two gears are meshed can be determined. The detection part 104 can intuitively observe the measured value of the gap when detecting it. At the same time, when the bracket 106 moves upward to the preset position, the recording pen 110 can contact the recording paper 109. When the detection shaft 102 rotates and swings, the recording pen 110 can follow its rotation to record. After the tip of the pen 110 contacts the recording paper 109, as the recording pen 110 swings, the path of the detection shaft 102 rotating can be recorded on the recording paper 109 by using the ink of the recording pen 110, thereby achieving the purpose of automatically recording the measured value for subsequent tracing. Furthermore, after the detection is completed, the position of the bracket 106 is reset to allow the positioning portion 103 to cancel the fixation of the gear, remove the gear, put in the next batch of two gears, and continue to move the bracket 106 upward through the driving component. When the bracket 106 moves upward to the preset position, the position of the recording paper 109 can also be moved. The first box body 107 reels the recording paper 109, and the second box body 108 releases the recording paper 109, allowing the recording paper 109 to be recorded. 9 moves a preset distance so that the last recorded measurement value can be rolled up in the first box body 107. The next recording is made on a new end of the recording paper 109, thereby achieving the purpose of classified recording. Compared with the detection equipment in the prior art, the present application only requires the operator to take and place the gears and turn on or off the driving components. During the detection, the detection unit 104 can intuitively display the value of this detection, and the recording unit 105 can record the value of this detection for subsequent tracing, thereby solving the problem that the detection operation in the prior art is relatively cumbersome, and the operator needs to detect and record the gears one by one, which requires manual operation, is highly complex, and is prone to human errors.

[0061] As a further solution of the present invention, the positioning portion 103 includes a fixing port 200 opened on the positioning shaft 101 and the detection shaft 102, a fixing block 201 is slidably connected in the fixing port 200, a connecting shaft 202 is provided in the positioning shaft 101 and the detection shaft 102, a connecting rod 203 is rotatably connected between the connecting shaft 202 and the fixing block 201, the connecting shaft 202 in the positioning shaft 101 is fixed to the bracket 106, the bottom of the connecting shaft 202 in the detection shaft 102 is rotatably connected to the support shaft 204, the support shaft 204 is fixed to the bracket 106, and the connecting shaft 202 in the detection shaft 102 is slidably connected to the detection shaft 102;

[0062] By setting the connecting shaft 202, when the bracket 106 moves upward, it can drive the connecting shaft 202 to move upward. The movement of the connecting shaft 202 can utilize the connecting rod 203 to displace the position of the fixed block 201. When the gear is sleeved on the fixed shaft and the detection shaft 102, the fixed block 201 contacts the inner wall of the gear, and the gear can be fixed by the force of the fixed block 201. Furthermore, the support shaft 204 can support the position of the connecting shaft 202 in the detection shaft 102 to ensure that when the detection shaft 102 rotates subsequently, it can drive the connecting shaft 202 to rotate together to avoid the problem of motion interference.

[0063] As a further solution of the present invention, the driving component includes a rotating shaft 300 rotatably connected to the detection tool 100, the rotating shaft 300 extends to the top of the bracket 106, and a screw 301 threadedly connected to the bracket 106 is provided on the rotating shaft 300, and a motor 302 is provided in the detection tool 100, and a driving shaft of the motor 302 and the rotating shaft 300 are respectively connected to mutually meshing transmission gears 303;

[0064] By setting the motor 302, when in use, the motor 302 can be started, and the rotation of the drive shaft of the motor 302 can rotate the shaft 300 through the transmission gear 303. The rotation of the shaft 300 can rotate the screw rod 301 to utilize the force of the thread to move the bracket 106 upward or downward.

[0065] As a further solution of the present invention, the driving component also includes a first driving disk 304 slidably connected to the top of the rotating shaft 300, the first driving disk 304 is rotatably connected to the bracket 106, a connecting opening 305 is opened on the detection tool 100, a first shaft 306 is rotatably connected in the connecting opening 305, a second shaft 307 is connected to one side of the positioning shaft 101, a support rod 308 is connected to the detection tool 100, and a third shaft 309 is connected to the support rod 308, a first bevel gear 310 is rotatably connected to the first shaft 306, and the second shaft 307 is rotatably connected to the first bevel gear 310. The third shaft 309 is rotatably connected with a third bevel gear 312 meshing with the second bevel gear 311, the first shaft 306 and the third shaft 309 are respectively connected with a first gear 313, a connecting frame 314 is provided on the detection shaft 102, and two second gears 315 meshing with the two first gears 313 are provided on the connecting frame 314, a second driving disk 316 is provided at the bottom of the third shaft 309, a driving rod 317 is provided on the first driving disk 304, a driving groove 318 is provided at the bottom of the second driving disk 316, and the first gear 313 is an incomplete gear;

[0066] By setting the first driving disk 304, when the rotating shaft 300 rotates to move the bracket 106 upward through the screw rod 301, the bracket 106 can drive the first driving disk 304 to move upward. When the first driving disk 304 moves linearly, it can also rotate with the rotating shaft 300. When the first driving disk 304 moves upward to a preset position, the set driving rod 317 can be sleeved in the driving groove 318. When the rotating shaft 300 continues to rotate, the first driving disk 304 can rotate the second driving disk 316 through the driving rod 317 and the driving groove 318. The rotation of the second driving disk 316 can be realized through the third shaft 309, the third bevel gear 312, the second shaft 307, the second bevel gear 311, the first bevel gear 312, the second shaft 307, the second bevel gear 312, the first bevel gear 313, the second bevel gear 314, the first bevel gear 315, the second bevel gear 316, the first bevel gear 317, the first bevel gear 318, the second bevel gear 319, the first bevel gear 319, the first bevel gear 311, the first bevel gear 312, the second bevel gear 313, the first bevel gear 314, the first bevel gear 315, the first bevel gear 316, the first bevel gear 316, the first bevel gear 317, the first bevel gear 318, the first bevel gear 319, the first bevel gear 319, the first bevel gear 319, the first bevel gear 319, the first bevel gear 31 A shaft 306 and a first bevel gear 310 rotate, and the first shaft 306 and the third shaft 309 have different rotation directions. The first gear 313 provided on the third shaft 309 and the first shaft 306 rotates accordingly. When the first gear 313 on the first shaft 306 is engaged with the second gear 315, the second gear 315 can be driven to rotate, and the detection shaft 102 can be rotated through the connecting frame 314. When the first gear 313 on the first shaft 306 is disengaged from the second gear 315, the first gear 313 on the third shaft 309 is engaged with the second gear 315, and the detection shaft 102 is rotated through the connecting frame 314, so that the purpose of allowing the detection shaft 102 to rotate clockwise and counterclockwise can be achieved.

[0067] As a further solution of the present invention, a connecting groove 400 is provided in the screw rod 301, the screw rod 301 is rotatably connected to the rotating shaft 300, the rotating shaft 300 is connected to a connecting ring 401 rotatably connected to the connecting groove 400, a plurality of first clamping grooves 402 are provided on the outer wall of the connecting ring 401, the first clamping groove 402 is a semi-spherical groove, a first connecting port 403 corresponding to the first clamping groove 402 is provided on the side wall of the connecting groove 400, a first push rod 404 adapted to the first clamping groove 402 is slidably connected in the first connecting port 403, and a first spring 405 is connected between the first push rod 404 and the first connecting port 403;

[0068] By setting the connecting ring 401, the screw rod 301 can be rotated through the friction between the first slot 402 and the first push rod 404 when the rotating shaft 300 rotates. When the bracket 106 moves upward to allow the connecting shaft 202 to move upward to the limit position, the movement of the bracket 106 is restricted. When the rotating shaft 300 continues to rotate, the first slot 402 can touch the first push rod 404, so that the first push rod 404 shrinks in the first connecting port 403, that is, the rotating shaft 300 and the connecting ring 401 idle in the screw rod 301. While ensuring that the bracket 106 can be moved, the rotating shaft 300 can continue to rotate after the bracket 106 moves to the limit position, so as to achieve the purpose of first fixing the gear and then rotating the detection shaft 102.

[0069] As a further solution of the present invention, the outer wall of the connecting frame 314 is provided with a plurality of second slots 406, the second gear 315 is rotatably connected to the connecting frame 314, the second slots 406 are semi-spherical slots, the inner wall of the second gear 315 is provided with a plurality of second connecting ports 407 corresponding to the second slots 406, a second push rod 408 is provided in the second connecting port 407, and a second spring 409 is connected between the second push rod 408 and the second connecting port 407;

[0070] By setting the second spring 409, in the initial state, the second spring 409 can press the position of the second push rod 408, and one end of the second push rod 408 can generate a certain friction force after being sleeved with the second slot 406. When the second gear 315 rotates, the friction force can be used to rotate the connecting frame 314, thereby driving the detection shaft 102 to rotate. After the detection shaft 102 drives the gear to rotate until the limit distance of the gap, the rotation of the detection shaft 102 is limited. When the first gear 313 is not yet disengaged from the second gear 315, the second gear 315 continues to rotate, and one end of the second top rod 408 is squeezed by the second top groove and shrinks into the second connecting port 407, that is, the second gear 315 idles on the connecting frame 314. While ensuring that the detection shaft 102 can rotate with the second gear 315, it can also avoid the problem of inconsistent rotation angles of the detection shaft 102 due to inconsistent gaps between different gears. When the first gear 313 and the second gear 315 are not completely disengaged, the second gear 315 is restricted and cannot rotate, causing motion conflict.
