Embodiment 2

[0052] 2. The present invention adopts two kinds of schemes in the friction test mode, one adopts the direct test scheme of the load cell, and the measurement is more accurate, such as figure 2 with Figure 8 Shown embodiment one and embodiment three; Another kind is to adopt the scheme that obtains friction force again after testing the friction pair torque, avoided the impact of vibration and heat on the test, such as Figure 7 Shown embodiment two;

[0053] 3, in the test equipment of the present invention, a vibrator has been applied as a vibration excitation device, and under the influence of vibration, the friction and wear test test work of the friction pair can be completed;

[0054] 4. In order to overcome the installation error and ensure that the contact of the friction pair is surface contact, the present invention avoids point contact or line contact in the design concept; a high-precision grinding wheel can be installed on the friction testing machine, so that...

Abstract

The invention discloses a vertical multifunctional friction-wear testing machine. The vertical multifunctional friction-wear testing machine comprises a testing machine body, wherein a main shaft tankis arranged at the upper part of the testing machine body, a rotating disc, a grinding wheel and a fixed disc are arranged on the main shaft tank, the rotating disc is detachably arranged, the main shaft is driven by a steering device in a bearing so as to rotationally arrange the rotating disc in the main shaft tank, and a detachable vibrator and a detachable heater are arranged on the rotatingdisc; the grinding wheel is detachably arranged; the fixed disc is fixed at the top end of the main shaft tank; and the friction block is arranged on the rotating disc or the fixed disc, and a detachable testing device is arranged on the friction block. According to the vertical multifunctional friction-wear testing machine by utilizing a new-form friction pair, namely that the rotating disc is mounted in the bearing, the rotating disc and the fixed disc have relatively high coaxial precisions, so that the coaxiality between the rotating disc and the fixed disc is well guaranteed, the rotatingdisc can smoothly rotate along the axial direction, and the situations that the contact among a suspending and rotary swing head at the shaft end of the rotating disc, the friction block and the friction disc (fixed disc or rotating disc) is poor, and the friction pair cannot work stably are avoided.

Description

technical field [0001] The invention relates to the technical field of metal friction tests, in particular to a vertical multifunctional friction and wear testing machine. Background technique [0002] At present, in the friction and wear test of metal materials, the pin-on-disk type friction and wear testing machine is more popular. Its function is to conduct friction and wear only for the properties of the metal material itself, regardless of the practical effect of the actual structure and movement form. Trial test. However, the processing, assembly and running precision of the equipment are all required to be relatively high. However, the structure of the common pin-on-disk friction testing machine and its actual use all show certain limitations, and cannot fully meet the above technical requirements, and there are still the following insurmountable defects: [0003] 1. The axial and radial runout of the rotating disc plane is relatively large, and the rotating disc pl...
