Technical Field
[0001] The utility model relates to the technical field of rolling bearing detection, in particular to a device for measuring the cone angle of a tapered roller with a modified rolling surface. Background Art
[0002] The cone angle of the tapered roller is closely related to the life and performance of the tapered roller bearing. At present, the cone angle measurement of the tapered roller is to compensate the cone angle of the tapered roller through the angle table, so that the cone angle deviation is converted into the difference between the indications of any two points on the generatrix of the tapered roller. During the measurement, the roller to be measured is placed on the angle table, and the indications of any two points on the generatrix of the measured roller are measured within the entire generatrix range except the chamfer. When the difference between the indications of any two points is less than the angular deviation of the measured bearing, the cone angle of the measured roller is considered to be qualified.
[0003] In order to reduce stress concentration during use, the rolling surface of tapered roller bearings is usually designed as a curved surface structure that is slightly convex outward. However, when the convexity of the roller rolling surface is large, the amount of modification of the rolling surface will be much greater than the required deviation of the taper angle. Therefore, the original measurement device and method are not suitable for measuring the taper angle of tapered rollers with modified rolling surfaces.
[0004] In view of this, this scheme proposes a new measuring device and method to solve the measurement problem of the cone angle of a tapered roller with a modified rolling surface. Utility Model Content

[0024] Embodiment 1
[0025] In order to more clearly describe the specific structure and measurement process of the measuring device, Figure 1-2 Describe this embodiment:
[0026] A measuring device for the cone angle of a tapered roller with a modified rolling surface, mainly composed of a platform 1, an operating table assembly 2, a guide rail bracket 3, a guide rail 4 and a measuring table assembly 5, wherein a measured roller 6 is a tapered roller with a modified rolling surface;
[0027] The operating table assembly 2 includes an angle adjustment table 201 and a displacement adjustment table 202 for placing the measured roller 6. A limit groove for installing the measured roller 6 is provided on the table surface of the angle adjustment table 201. The angle adjustment table 201 is installed on the platform 1 through the displacement adjustment table 202. The measured roller 6 and the angle adjustment table 201 move or rotate synchronously with the displacement adjustment table 202.
[0028] In this embodiment, the angle adjustment platform 201 is a standard angle platform, which is arranged above the displacement adjustment platform 202. The angle adjustment platform 201 can position the measured roller 6 and make the measured generatrix of the measured roller 6 horizontal, wherein the angle of the angle adjustment platform 201 is equal to the theoretical cone angle of the measured roller 6;
[0029] The displacement adjustment table 202 is installed above the platform 1 through a driving unit, and has the function of moving and rotating in the horizontal direction, and can adjust the position of the angle adjustment table 201 and the measured roller 6. It should be noted that: the driving unit used to control the movement of the displacement adjustment table is a prior art, and technicians in this field can make a reasonable choice according to actual conditions, and this solution will not be described in detail;
[0030] An operating table assembly 2 is arranged in the middle of the platform 1 , and guide rail brackets 3 are arranged on both sides of the platform. The guide rail brackets 3 are arranged on both sides of the platform 1 and are ordinary brackets for supporting the guide rails 4 .
[0031] The guide rail 4 is arranged above the guide rail brackets 3, and the guide rail 4 is a straight guide rail, which guides the measuring table component 5;
[0032] The measuring meter assembly 5 includes at least one measuring meter installed on the guide rail 4. In the present embodiment, three measuring meters are selected, namely, measuring meter a501, measuring meter b502 and measuring meter c503; wherein, measuring meter a501 is fixed in the middle of the guide rail, and the measuring meters b502 and measuring meters c503 are symmetrically distributed on both sides of measuring meter a501 and can move laterally along the guide rail 4. Measuring meters b502 and measuring meters c503 are respectively installed on the guide rail 4 through driving assemblies, and when measuring meter b502 moves a certain distance to one side, measuring meter c503 will simultaneously move the same distance in the opposite direction along the guide rail under the guidance of the driving assembly and the guide rail 4.
[0033] It should be noted that the driving component installed in the measuring meter component 5 is set for the purpose of realizing synchronous displacement adjustment of the measuring meter b502 and the measuring meter c503 in opposite directions and the same distance. From its setting purpose, it can be seen that the driving component is a relatively conventional prior art. Technicians in this field can make reasonable choices in the prior art, such as adopting the following structure: the driving component is composed of a dual-axis motor and two oppositely installed screws, and the measuring meter b502 and the measuring meter c503 are respectively installed on the two screws through nuts. The motor rotates, driving the two measuring meters to move synchronously in opposite directions for the same distance at the same time.
[0034] This scheme adopts an angle adjustment table to compensate the cone angle of the tapered roller to be measured. On the basis of realizing the measurement of cone angle deviation, a symmetrical point measurement method is proposed to measure the height deviation of two symmetrical points on the rolling surface generatrix of the measured roller, thereby realizing the measurement of the cone angle of the tapered roller with modified rolling surface;
[0035] The method for measuring the cone angle of a tapered roller with a modified rolling surface based on the measuring device is as follows:
[0036] 1) Place the roller 6 to be measured on the angle adjustment table 201, and adjust the displacement adjustment table 202 so that the measuring table a501, the measuring table b502 and the measuring table c503 are in contact with the roller 6 to be measured;
[0037] 2) Adjust the positions of the displacement adjustment table 202 and the angle adjustment table 201 so that the measuring tables a501, b502 and c503 are on the generatrix of the measured roller 6, wherein the measuring table a501 is at the highest point on the generatrix of the measured roller 6, and the measuring tables b502 and c503 are symmetrical with respect to the measuring table a501;
[0038] 3) Adjust the positions of the probes of the measuring gauges b502 and c503 so that the probes of the measuring gauges b502 and c503 are as close as possible to the probe of the measuring gauge a501, and prepare for measurement;
[0039] 4) Start the driving assembly to move the measuring table b502 to the left, and at the same time, the measuring table c503 moves to the right under the guidance of the guide rail 4, and the moving distance of the measuring table c503 and the measuring table b502 is always consistent;
[0040] 5) Record the difference between the indications of measuring scale b502 and measuring scale c503 during the movement. If the difference between the two is always smaller than the cone angle deviation, the cone angle of the measured roller 6 is qualified.
[0041] The parts not described in detail in this embodiment are prior art.
[0042] It should be noted that although the utility model is described through the above embodiments, the utility model can also have other multiple embodiments. Without departing from the spirit and scope of the utility model, it is obvious that those skilled in the art can make various corresponding changes and deformations to the utility model, but these changes and deformations should all fall within the scope of protection of the attached claims of the utility model and their equivalents.
