specific Embodiment approach 1

[0035] Specific implementation mode one, the following combination figure 1 To illustrate this embodiment, since there is no optimal method to measure the R value of a small arc and a large radius, the present invention aims to solve the problem of measuring the radius of a discontinuous arc on the end face of a tapered roller.

[0036] To achieve the above object, the present invention provides a tapered roller end face radius measuring device, which includes a measuring platform 1, a sensor 2, a measuring needle 3 and a profiler 4, the top of the measuring platform 1 is provided with a pit 1-1, and the pit 1- 1 is used to place the tapered roller, and the profiler 4 is fixed next to the measuring platform 1 through a column. The profiler 1 is connected to the sensor 2, and the sensor 2 is connected to the stylus 3. The sensor 2 is used to receive the sensing data of the stylus 3. The profiler 4 is used to receive the data from the sensor 4, the stylus 3 is used to measure th...

specific Embodiment approach 2

[0038] Specific Embodiment 2. In the tapered roller end surface radius measuring device of the present invention, the said dimple 1-1 is in a concave shape, which is used to fix the tapered roller, and the upper surface of the dimple 1-1 is connected to the lower surface of the tapered roller. fit.

[0039] The pit 1-1 can fix the tapered roller to be detected.

specific Embodiment approach 3

[0040] Specific embodiment three, tapered roller end surface radius measuring device of the present invention, described profiler 4 is PGI830 type profiler and is produced by British Taylor Hobson Company, and sensor 2 also adopts the standard configuration sensor of PGI830 type profiler.

[0041] The measurement accuracy of the profiler 4 is high and the measurement is precise.

Abstract

The invention provides a tapered roller end face radius measuring device and method to solve the measuring problem of the radius of the discontinuous arc of the end face of a tapered roller. The tapered roller end face radius measuring device comprises a measuring table, a sensor, a measuring probe and a contourgraph. A pit is formed in the top end of the measuring table, the contourgraph is fixedbeside the measuring table, and the contourgraph and the measuring probe are both connected with the sensor. The measuring method comprises the steps that firstly, the tapered roller is placed on themeasuring table, the measuring probe makes contact with the edge of the end face pit and the measuring range is adjusted; secondly, a front-back knob of the measuring table is rotated, a contact number of the measuring probe is observed, and the knob is adjusted to the position with the maximum diameter of the end face of the tapered roller; and thirdly, the measuring probe is made to be in contact with the end face of the tapered roller in the whole process, the measuring probe carries out contact type measurement from one end of the tapered roller to the other end of the tapered roller, thejourney of the measuring probe is made to cover the contour section of the whole tapered roller, the sensor senses the journey track of the measuring probe, and the contourgraph receives data of thesensor and generates a contour curve at the position with the maximum diameter; and the first step to the third step are repeated to measure for many times, and an average value is obtained.

Description

technical field [0001] The invention relates to the technical field of mechanical measurement, in particular to the measurement technology of the end face radius of a tapered roller. Background technique [0002] The roller is the component that bears the load when the bearing is running, and it is the weakest part in the roller bearing. Its manufacturing quality has a great influence on the working performance of the bearing (such as rotation accuracy, vibration, noise and flexibility, etc.). The main factor of bearing service life. [0003] There are many types of rollers. According to the shape and size, there are tapered rollers, cylindrical rollers, spherical rollers, spiral rollers and various needle rollers. [0004] For tapered rollers, a lot of work needs to be done in product failure analysis, among which accurate and reliable measurement data is the foundation and guarantee. [0005] In the process of tapered roller fault analysis, it is necessary to measure the...
