Working principle of vertical universal friction and wear tester

As an institution specializing in R & D and production of friction and wear testing machine, Ji'nan Heng Xu Testing Machine Technology Co., Ltd. has summed up the working principle of vertical universal friction and wear testing machine for many years.

The working principle of the friction and wear tester is the friction between the grind layer and the friction paper, which are rubbed at the prescribed speed under the action of the load friction body. The wear resistance of the ink layer (or coating) is judged by measuring the reduction in density before or after friction (or the reduction of coating thickness).

The vertical universal friction and wear tester can be used for different tests according to different uses and different friction pairs. Here are some brief examples.

1. ring friction: it is used to study the running in property of medium carbon steel under the lubrication condition of surface nanocrystallization. Principle: the ring specimen is installed with the lower end of the spindle through a special fixture. The disc specimen is installed in the tray and loaded through the force system under the tray. The spindle is driven by the DC motor to drive the pin sample to rotate.

2. pin friction: used to investigate the effect of nanoparticles on the friction and wear properties of materials in dry friction condition.

3. four ball friction:

1) friction and wear tests for trace lubricants used as vulcanized isobutene.

2) investigate the friction and wear properties of oils and additives.

3) the steel ball is rotated under test and the steel ball is fixed. The load is loaded on the 3 fixed steel by the sensor.

On the ball. The friction and wear properties of ultrafine manganese phosphate conversion coating were studied.

4. by fixing the steel plate at the lower end, the nylon ring is clamped and rotated by the test fixture to inspect nylon parts.

Friction and wear properties.

5. coating friction:

1) the wear characteristics of Al2O3 - 13wt.% TiO2 ceramic coating and WC cemented carbide friction pair under dry friction condition.

2) dry friction and wear properties of flame sprayed ETFE coatings.

The test machine should be checked every 1-2 years to ensure the correctness of the indicators. For unambiguous failures, customers should contact with our company in time for proper solution.
