Embodiment 1

[0032] Example 1: The following spherical sample is used as the friction pair material, and the friction and wear test is carried out with the pair of the German Evonik P84NT1 polyimide molded product pair, and the temperature of the friction pair material of the spherical sample is measured by the temperature measuring component 17 The change.

[0033] Such as Figure 1 to Figure 5 As shown, the present invention discloses a temperature measuring device, which includes a hollow base 12 , an extension rod 11 , a locking cap 13 , a snap spring 14 , a top post 15 , and a temperature measuring component 17 . The connection relationship is as follows: the locking cap 13 and the snap spring 14 are buckled and connected through the convex ring 131 and the annular slot 141, and the upper and lower ends of the hollow base 12 are respectively connected with the locking cap 13 and the extension rod 11 by bolts. The cap 13 locks the circlip 14 to clamp the material of the friction pair ...

Embodiment 2

[0044] Embodiment 2: Others are the same as in Embodiment 1, the difference is that the test object of this embodiment is a cylindrical friction pair 20, so this embodiment omits the concave hemispherical support column 19, and the cylindrical friction pair 20 is directly in contact with the top column 15 .

[0045] The temperature measuring device 1 of the present invention is not only capable of testing spherical geometric samples and cylinders, but also can test the temperature changes during the friction and wear process of cones, cubic friction pair materials and the like. According to different shapes of the friction pair, select the corresponding support column to contact the top column 15, and improve the thermal conductivity through the support column, so as to solve the problem of insufficient thermal conductivity of the material of the friction pair and the top column 15 in direct contact.

Description

technical field [0001] The invention belongs to the detection field of friction and wear testing machines, and relates to a temperature measurement technology for friction pair materials, in particular to a temperature measuring device and a temperature measurement method during the friction process of friction pair materials, which can non-destructively detect friction pair materials in the friction and wear process temperature change. Background technique [0002] The friction and wear testing machine mainly determines the anti-friction and anti-wear properties of the material application by detecting the friction coefficient and wear rate of the material. During the rotation or reciprocating motion of the friction pair material, based on the material, roughness, and mechanical properties of the counterpart material, as well as the environment in the friction process, frictional thermal effects will inevitably occur on the contact surface. The generation, accumulation and...
