DETAILED DESCRIPTION

[0026] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0027] Reference below Figure 1-Figure 5 The measuring device 100 for the reducer bearing gasket of the embodiment of the utility model is described, which automatically measures the height between the upper end face 311 of the bearing of the main housing 3 and the first connecting face 32 as the first height, and simultaneously automatically measures the height between the second connecting face 42 of the end cover 4 and the inner bottom wall 411 of the bearing chamber 41 as the second height, and selects a gasket of appropriate thickness by the difference between the two heights, with high accuracy and efficiency.

[0028] like Figure 1-5 As shown, a measuring device 100 for a reducer bearing gasket according to an embodiment of the utility model, the reducer comprises a main housing 3 and an end cover 4, the main housing 3 is provided with a first connecting surface 32 and the end cover 4 is provided with a second connecting surface 42, and the first connecting surface 32 and the second connecting surface 42 are connected.

[0029] The measuring device 100 comprises: a first measuring mechanism 1 and a second measuring mechanism 2, both of which comprise a lifting portion 11 and a sensing component 12, wherein the sensing component 12 is located at the end of the lifting portion 11, and the lifting portion 11 is suitable for driving the sensing component 12 to lift and lower; the first measuring mechanism 1 and the second measuring mechanism 2 are both in two groups, wherein the sensing component 12 of the first measuring mechanism 1 of one group is used to measure the position of the upper end surface 311 of the bearing of the reducer transmission shaft, and the sensing component 12 of the second measuring mechanism 2 is used to measure the position of the first connecting surface 32, and the sensing component 12 of the first measuring mechanism 1 of the other group is used to measure the position of the inner bottom wall 411 of the bearing chamber 41 of the end cover 4, and the sensing component 12 of the second measuring mechanism 2 is used to measure the position of the second connecting surface 42.

[0030] In practice, the measuring device 100 is electrically controlled, and the lifting part 11 of the first measuring mechanism 1 and the second measuring mechanism 2 of the measuring device 100 can be driven by a motor to lift and lower. For example, the motor directly drives the lifting part 11 to lift and lower, or a sleeve is provided on the outside of the lifting part 11, the sleeve is provided with an internal thread, and the lifting part 11 is provided with an external thread. The motor drives the sleeve to rotate to drive the lifting part 11 to lift and lower. Of course, a hydraulic cylinder can also be used to drive the lifting part 11 to lift and lower. The embodiment of the utility model adopts a motor-driven method to make the lifting part 11 drive the sensing component 12 to lift and lower, so that the sensing component 12 can detect the position that needs to be detected.

[0031] Specifically, the device to be tested is the main housing 3 of the reducer and the end cover 4 of the reducer, a transmission shaft and a first connecting surface 32 are provided in the main housing 3, a bearing 31 is provided at the end of the transmission shaft exposed outside the main housing 3, and the end cover 4 is provided with a bearing chamber 41 and a second connecting surface 42; during actual connection, the end cover 4 of the reducer is buckled on the main housing 3, and the second connecting surface 42 and the first connecting surface 32 are connected, and the position of the transmission shaft in the main housing 3 exposed outside the main housing 3 and the bearing 31 are both extended into the bearing chamber 41 of the end cover 4, and after the first connecting surface 32 and the second connecting surface 42 are connected, a large gap is provided between the bearing 31 and the inner bottom wall 411 of the bearing chamber 41, therefore, it is necessary to set a gasket of appropriate thickness to adjust the preload of the bearing 31 to prevent the bearing 31 from axial displacement.

[0032] When selecting the thickness of the gasket, refer to Figure 1 As shown, the main housing 3 of the reducer is placed on the ground or a measuring table with the first connecting surface 32 facing upward, and the end cover 4 is placed on the ground or a measuring table with the second connecting surface 42 facing upward, then the bearing 31 at the end of the transmission shaft in the main housing 3 is located at the upper end, and at the same time, the bearing chamber 41 of the end cover 4 is formed by a local depression of the end cover 4 along the second connecting surface 42 in a direction away from the second connecting surface 42.

[0033] Therefore, one group of first measuring mechanisms 1 is used to measure the position of the upper end face 311 of the bearing, and the second measuring mechanism 2 is used to measure the position of the first connecting surface 32, and it can be concluded that the distance between the upper end face 311 of the bearing and the first connecting surface 32 is the first height H1; another group of first measuring mechanisms 1 measures the position of the inner bottom wall 411 of the bearing chamber 41, and the second measuring mechanism 2 is used to measure the position of the second connecting surface 42, and it can be concluded that the distance between the second connecting surface 42 and the inner bottom wall 411 of the bearing chamber 41 is the second height H2, and the difference between the second height H2 and the first height H1 can be used to determine the thickness of the axially set gasket.

[0034] Further, each set of measuring mechanisms includes a first measuring mechanism 1 and a second measuring mechanism 2, wherein when the lifting portion 11 of the first measuring mechanism 1 of one set moves downward, the sensing component 12 of the first measuring mechanism 1 is used to sense the position of the upper end surface 311 of the bearing, and the lifting portion 11 of the second measuring mechanism 2 moves downward and is used to sense the position of the first connecting surface 32; thus, the first height H1 is obtained through the position of the upper end surface 311 of the bearing and the position of the first connecting surface 32, as shown in FIG. Figure 1 As shown in H1.

[0035] Similarly, when the lifting portion 11 of the first measuring mechanism 1 of another group moves downward, the sensing component 12 of the first measuring mechanism 1 is used to sense the position of the inner bottom wall 411 of the bearing chamber 41, and the sensing component 12 of the second measuring mechanism 2 is used to sense the position of the second connecting surface 42. The second height H2 can be obtained through these two positions. Then, when the end cover 4 is buckled on the main shell 3 and connected at their respective connecting surface positions, the difference between the first height and the second height is the gap left in the bearing chamber 41 after the transmission shaft and the bearing 31 extend into the bearing chamber 41. By measuring the gap, the thickness of the gasket used can be determined.

[0036] In the embodiment of the utility model, the first measuring mechanism 1 and the second measuring mechanism 2 of the measuring device 100 are divided into two groups. The first measuring mechanism 1 and the second measuring mechanism 2 of one group are used to measure the first height while the first measuring mechanism 1 and the second measuring mechanism 2 of the other group are used to measure the second height. Both of them are electrically controlled. The data measured by the sensing component 12 is stored and output, so as to measure the thickness of the required gasket, thereby improving the measurement efficiency and having a high accuracy.

[0037] In some embodiments, the sensing component 12 includes a connecting plate 121 and a sensor 122. The lifting portion 11 is connected to the connecting plate 121 and drives the connecting plate 121 to rise and fall when lifting. The sensor 122 is connected to the connecting plate 121; wherein the sensor 122 is in contact with the upper end surface 311 of the bearing, or the first connecting surface 32, or the inner bottom wall 411 of the bearing chamber 41, or the second connecting surface 42 for sensing.

[0038] In practice, the connecting plate 121 is connected to the end of the lifting part 11, and the sensor 122 is connected to the side of the connecting plate 121 facing the main housing 3 of the reducer or the end cover 4 of the reducer. The lifting part 11 is movably connected to the top of the entire measuring device 100. The lifting part 11 is lifted and lowered from the top of the measuring device 100 to make the sensor 122 more conveniently and efficiently contact the upper end surface 311 or the first connecting surface 32 of the bearing, or the inner bottom wall 411 or the second connecting surface 42 of the bearing chamber 41, and it can be lifted up when not in use, thereby saving space.

[0039] The sensor 122 is a position sensor 122 , and the sensor 122 of the first measuring mechanism 1 and the sensor 122 of the second measuring mechanism 2 of each group can be set to be the same, and the lifting principle of the lifting part 11 is the same, which can meet the need to measure the position to be measured.

[0040] Specifically, the sensor 122 of the first measuring mechanism 1 of one group is used to contact the upper end surface 311 of the bearing and measure the position of the upper end surface 311 of the bearing, and the sensor 122 of the second measuring mechanism 2 of the group is used to contact the first connecting surface 32 and measure the position of the first connecting surface 32, so that the first height is obtained based on these two positions; similarly, the sensor 122 of the first measuring mechanism 1 of another group is in contact with the inner bottom wall 411 of the bearing chamber 41 and is used to measure the position of the inner bottom wall 411 of the bearing chamber 41, and the sensor 122 of the second measuring mechanism 2 of the group is in contact with the second connecting surface 42 and is used to measure the position of the second connecting surface 42, and the second height is obtained through these two positions, and the position is measured by the sensor 122 contacting the position to be measured, and the measurement accuracy is high.

[0041] In some embodiments, there are multiple sensors 122 , and the multiple sensors 122 are distributed on the connecting plate 121 at intervals. The connecting plate 121 is parallel to the horizontal plane, and the multiple sensors 122 have the same height.

[0042] In practice, the measurement accuracy can be improved by providing multiple sensors 122. For example, when different positions of the upper end surface 311 of the bearing produce a small error or a small face difference, the position of the upper end surface 311 of the bearing is calculated by taking the average value of the measurement data of multiple sensors 122. Therefore, by connecting multiple sensors 122 to the connecting plate 121, the dispersed arrangement of multiple sensors 122 is facilitated, and the measurement accuracy is improved.

[0043] Furthermore, by setting the connecting plate 121 parallel to the horizontal plane, the heights of the multiple sensors 122 can be made consistent, and when the multiple sensors 122 are dispersedly connected to the connecting plate 121, the measurement position error caused by the installation height difference of the multiple sensors 122 can be prevented. For example, when the multiple sensors 122 are the same type of sensors 122 and the connecting plate 121 is parallel to the horizontal plane, the accuracy of the measurement position of the sensor 122 is improved.

[0044] In some embodiments, there are three sensors 122 , and the three sensors 122 are distributed on the connecting board 121 in a triangle shape.

[0045] Reference Figure 3As shown, three sensors 122 are arranged, and the three sensors 122 are distributed in a triangular shape, preferably an equilateral triangle shape. For example, when the three sensors 122 measure the position of the upper end surface 311 of the bearing, the three sensors 122 can be distributed in different directions of the center of the bearing 31 and contact the upper end surface 311 of the bearing, so that the position of the upper end surface 311 of the bearing can be basically determined. Therefore, by setting three sensors 122, the position of the upper end surface 311 of the bearing, or the position of the first connecting surface 32, or the position of the second connecting surface 42, or the position of the inner bottom wall 411 of the bearing chamber 41 can be measured more accurately. The number of sensors 122 is more reasonable and can make the measurement more accurate.

[0046] In some embodiments, an elastic member is disposed between the sensor 122 and the connecting plate 121 so that the sensor 122 is elastically pressed against the upper end surface 311 of the bearing, or the first connecting surface 32 , or the inner bottom wall 411 of the bearing chamber 41 , or the second connecting surface 42 .

[0047] In practice, when the measuring device 100 automatically detects the height from the upper end face 311 of the bearing to the first connecting face 32 of the reducer, the input shaft 7 is a ball bearing 31, and static measurement can be used; the intermediate shaft 6 and the output shaft 5 of the reducer are tapered bearings 31, and dynamic measurement can be used, such as the transmission shaft driving the bearing 31 to rotate to eliminate the clearance of the bearing 31, thereby ensuring the accuracy and consistency of the measurement, saving labor, and improving production efficiency.

[0048] Therefore, by setting an elastic member between the sensor 122 and the connecting plate 121, when the bearing 31 rotates, the sensor 122 can be brought into contact with the upper end surface 311 of the bearing to measure the position of the upper end surface 311 of the bearing, and the normal rotation of the bearing 31 can be ensured, while also having a certain protective effect on the sensor 122.

[0049] In some embodiments, the lifting portion 11 includes a first connecting shaft 111 and a second connecting shaft 112 that are detachably connected, and the second connecting shaft 112 and the first connecting shaft 111 are axially connected to each other, and the connecting plate 121 is detachably connected to the second connecting shaft 112 .

[0050] Reference Figure 2 As shown, the first connecting shaft 111 and the second connecting shaft 112 can be arranged to be connected by a connecting piece or by a threaded connection. One end of the first connecting shaft 111 is connected to the top of the measuring device 100, and the second connecting shaft 112 is connected to the other end of the first connecting shaft 111. The connecting plate 121 is detachably connected to the second connecting shaft 112. Then, when the second connecting shaft 112, the connecting plate 121 or the sensor 122 fails, it is convenient to replace them without replacing the entire lifting part 11. Only the second connecting shaft 112, the connecting plate 121 and the sensor 122 at the end need to be disassembled and replaced.

[0051] In some embodiments, the second connecting shaft 112 in a group of the first measuring mechanism 1 is also connected to the positioning shaft 13, and a positioning portion 14 is provided at the bottom of the positioning shaft 13. The positioning portion 14 is suitable for extending into the center hole of the bearing 31 for positioning when the sensor 122 contacts the upper end surface 311 of the bearing.

[0052] In practice, when the first measuring mechanism 1 measures the position of the upper end surface 311 of the bearing, the lifting part 11 drives the connecting plate 121 to descend, so that the sensor 122 on the connecting plate 121 contacts the upper end surface 311 of the bearing, and the positioning part 14 is located in the center hole of the bearing 31; that is, the height of the sensor 122 arranged on the connecting plate 121 in the height direction of the lifting part 11 is less than the height of the positioning part 14, so that the positioning part 14 is located in the center hole of the bearing 31 and the sensor 122 contacts the upper end surface of the bearing 31; this method is suitable for the situation that the bearing 31 is rotating or static, especially when the bearing 31 rotates, the positioning part 14 can ensure the accuracy of the sensor 122 measuring the upper end surface 311 of the bearing. In addition, as the bearing 31 rotates, the three sensors 122 can collect multiple position data of the upper end surface 311 of the bearing. By averaging the multiple position data of the upper end surface 311 of the bearing, the position of the upper end surface 311 of the bearing can be judged more accurately, thereby improving the required gasket thickness for the final measurement.

[0053] Specifically, when installing the positioning part 14, a mounting hole can be set on the connecting plate 121, one end of the positioning part 14 is connected to the mounting hole, and the other end is exposed from the connecting plate 121. Of course, the design of the positioning part 14 needs to be combined with the measured size of the center hole of the bearing 31. Therefore, the positioning part 14 is set to be detachable and installable, which is convenient for installing positioning parts 14 of different sizes according to actual conditions.

[0054] When installing the positioning part 14 in the embodiment of the utility model, the positioning shaft 13 is connected in the second connecting shaft 112, and a mounting groove is provided at the end of the positioning shaft 13. One end of the positioning shaft 13 with the mounting groove is inserted into the connecting plate 121, and one end of the positioning part 14 is connected to the mounting groove of the positioning shaft 13 and the other part is exposed on the connecting plate 121, so as to be positioned and matched with the bearing 31 to be measured.

[0055] When the first measuring mechanism 1 is used to measure the position of the inner bottom wall 411 of the bearing chamber 41, the positioning portion 14 is not required, and the sensor 122 at the bottom of the connecting plate 121 can be in contact with the inner bottom wall 411 of the bearing chamber 41. When the second measuring mechanism 2 has the same structure as the first measuring mechanism 1, the second measuring mechanism 2 also does not need to be provided with the positioning portion 14.

[0056] In some embodiments, a diameter of the first connecting shaft 111 is greater than a diameter of the second connecting shaft 112 , and an axial length of the first connecting shaft 111 is greater than an axial length of the second connecting shaft 111 .

[0057] In practice, by making the diameter of the first connecting shaft 111 larger than the diameter of the second connecting shaft 112 and setting the length of the first connecting shaft 111 to be longer, the first connecting shaft 111 can be used as the main body of the lifting part 11 to ensure the lifting height requirement of the lifting part 11; and the second connecting shaft 112 is mainly used to connect the connecting plate 121, and is detachably connected to the first connecting shaft 111. When the sensor 122 or the connecting plate 121 is worn, there is no need to replace the entire lifting part 11, but only the smaller first connecting shaft 111 and the connecting plate 121 need to be replaced, which reduces the replacement cost and makes replacement more convenient.

[0058] In some embodiments, a protective sleeve 15 is provided at the connection between the first connecting shaft 111 and the second connecting shaft 112, and a reinforcing sleeve 16 is provided at the connection between the connecting plate 121 and the second connecting shaft 112. The upper end of the reinforcing sleeve 16 passes through the protective sleeve 15 through a connecting piece and is connected to the first connecting shaft 111.

[0059] In practice, a protective cover 15 is provided at the connection between the first connecting shaft 111 and the second connecting shaft 112, and the diameter of the first connecting shaft 111 is greater than the diameter of the second connecting shaft 112. Then, the corresponding upper end diameter of the protective cover 15 is greater than the lower end diameter, thereby ensuring the integrity of the first connecting shaft 111 and the second connecting shaft 112 and improving the stability of the connection between the first connecting shaft 111 and the second connecting shaft 112.

[0060] In addition, the middle part of the side of the connecting plate 121 away from the sensor 122 protrudes to form a protruding structure 124, which is used to connect the second connecting shaft 112, thereby improving the connection strength between the connecting plate 121 and the second connecting shaft 112. A reinforcing sleeve 16 is arranged at the periphery of the connection between the connecting plate 121 and the second connecting shaft 112. The reinforcing sleeve 16 can be first clamped on the connecting plate 121, and then the reinforcing sleeve 16 can be reliably connected to the connecting plate 121 by screws passing through the connecting holes 123 of the connecting plate 121. The reinforcing sleeve 16 can further ensure the connection strength between the positioning shaft 13 and the connecting plate 121; and the upper end of the reinforcing sleeve 16 is connected with a connecting pin, which passes through the bottom of the protective sleeve 15 and the bottom edge of the first connecting shaft 111. The connecting pin is not shown in the figure, so that the reinforcing sleeve 16 is more fixed and reliable, and the stability of the reinforcing sleeve 16, the connecting plate 121, the first connecting shaft 111, etc. is increased, thereby improving the stability of the connecting plate 121 when the lifting part 11 drives the lifting.

[0061] In some embodiments, the measuring device 100 of the reducer bearing gasket also includes a plurality of stable support structures 17, which are spaced apart and connected to the connecting plate 121 around the lifting part 11, and the plurality of stable support structures 17 are also elastically connected to the top of the measuring device 100 so that the lifting part 11 drives the connecting plate 121 to rise and fall stably.

[0062] In practice, continue to refer to Figure 2 As shown, there are multiple stable support structures 17, and the multiple stable support structures 17 are evenly spaced around the lifting part 11; each stable support structure 17 includes a pull rod 172 and a support part 171, and the upper ends of the multiple support parts 171 can be connected as a whole through a fixing plate, and the lower end of the support part 171 is connected to the pull rod 172, and the lower part of each pull rod 172 is connected to the connecting plate 121, and the upper part is connected to the top of the measuring device 100; elastic material is partially set on the pull rod 172, so when the lifting part 11 drives the connecting plate 121 down, the pull rod 172 can be moved. When descending, the support part 171, the fixed plate, the lifting part 11 and the connecting plate 121 descend together, and the pull rod 172 can be stretched due to the local elastic material. That is, when the lifting part 11 drives the connecting plate 121 to descend, it is always pulled by the surrounding pull rods 172, and the upper ends of the surrounding multiple support parts 171 are connected by the fixed plate to ensure the force balance of the connecting plate 121, improve the stability of the connecting plate 121, and thus improve the stability of the sensor 122 connected to the connecting plate 121, so that the measurement result of the sensor 122 is more accurate.

[0063] It should be noted that the transmission shaft in the main housing 3 of the embodiment of the utility model includes an input shaft 7, an output shaft 5 and an intermediate shaft 6. The method used to measure the input shaft 7, the output shaft 5 and the intermediate shaft 6 is the same, that is, there are three transmission shafts at this time, so the corresponding first measuring mechanisms 1 can be set to three. The three first measuring mechanisms 1 correspond to measuring the position of the upper end surface 311 of one of the input shaft 7, the output shaft 5 and the intermediate shaft 6, thereby completing the simultaneous measurement of the input shaft 7, the output shaft 5 and the intermediate shaft 6.

[0064] In addition, the first connecting surface 32 of the actual reducer is provided with at least two positioning pins 33, which can position the main housing 3 of the reducer and the end cover 4 with the positioning hole 43 of the end cover 4 when the main housing 3 and the end cover 4 are connected; of course, a liftable positioning column can also be provided in the measuring equipment 100, so that the positioning column can be positioned with the positioning pin 33 after being lowered, thereby improving the stability of the main housing 3 of the reducer, thereby improving the accuracy of the measurement result. Similarly, the end cover 4 can also adopt the same method to increase stability.

[0065] In practice, the second measuring mechanism 2 may have the same overall structural setting as the first measuring mechanism 1, or the second measuring mechanism 2 may also be other structures, such as a sensor 122 is provided at the bottom of a lifting column, as long as the position of the first connecting surface 32 or the position of the second connecting surface 42 can be measured.
